Device for fastening the housing of a refrigerant compressor

FIELD OF THE INVENTION

STATE OF THE ART

The invention relates to a device for fastening the housing of a refrigerant compressor to a container enclosing a cooling volume, wherein the housing can be fastened by means of any number of connecting elements on a container arranged on the carrier element, wherein the at least one Verbmdungselement or at least one receptacle optionally can be arranged on the housing or on the support element according to the preamble of claim 1.

Such refrigerant compressors have long been known and are mainly used in refrigerators and shelves private and commercial users.

In the course of the refrigerant process, a refrigerant m is known manner by absorbing energy from the to be cooled

Room heated in an evaporator and finally superheated and pumped by means of the refrigerant compressor to a higher pressure level, where it gives off heat through a condenser and via a throttle, in which a pressure reduction and cooling of the refrigerant takes place, back into the evaporator again.

For this purpose, the refrigerant compressor has a hermetically sealed housing in the interior of which a refrigerant-compressing piston-cylinder motor arrangement operates in the following context, for the sake of simplicity, be referred to as a unit of work. The housing housing housing the work unit is subsequently positioned on a support element provided for this purpose and connected to the cooling system or to evaporator and capacitor lines of a refrigerator or cooling appliance.

The support element is usually designed plate-shaped and provides a footprint for the housing of the refrigerant compressor. Usually, such support elements are arranged in the region of the bottom or the rear wall of a container enclosing a cooling volume or of the cooling device.

To fasten the housing to the support element, use is made of a connecting element, which is usually designed as a screw connection. For example, from the prior art arrangements are known in which welded to the housing angle profiles are screwed by means of bolts on the support member. The distances of the connecting elements or the distances of corresponding, provided on the support member recordings are defined by einschlagige standards.

However, the installation of such screw is time consuming and - due to special housing and Tragerelemente geometries - often associated with considerable difficulties. The case required use of various assembly tools and a variety of components requires a relatively high installation and cost. Also, disassembly of the refrigerant compressor housing from the cooling unit or from the support element can often only be done by damaging the Kuhlgerates or the refrigerant compressor housing, since the screw is rusted. In addition to screw and adhesive joints for attachment of the refrigerant compressor housing on Tragerelement are known. Again, a component-friendly disassembly is hardly possible.

Also clamp connection are known, for example from WO 2006/092387 Al. However, the preparation of the terminal connections is connected in known refrigerant compressor housings with high assembly costs, as well as the disassembly.

PRESENTATION OF THE INVENTION

It is therefore the object of the present invention to enable a simplified and reliable attachment of the refrigerant compressor housing on each support member.

In particular, a mounting of the Kältemittelverdichter- housing on the support element to be made possible with little installation, component and time.

Furthermore, the attachment of the Kältemittelverdichter- housing on the support element should be reversible and can be easily solved if necessary.

These objects are achieved by a device according to the characterizing features of claim 1.

According to claim 1, a device for fixing the housing of a refrigerant compressor on a container enclosing a cooling volume comprises any number of connecting elements, by means of which the housing can be fastened to a carrier element arranged on the container, wherein at least one connecting element is provided, which in at least one corresponding receptacle clamping or latching can be fixed, wherein the at least one connecting element or the at least one receptacle can be optionally arranged on the housing or on the support element.

Erf mdungsgemaß the housing is movable from a first mounting position in which the at least one connecting element is threaded in the at least one receptacle, in an operating position in which the connecting element in the receptacle is clamped or locked.

In this way, by using the clamping or Verrastungstechnik not only the use of screws obsolete and thereby the assembly costs compared to an attachment by means of screws much easier, but also, compared to conventional clamping and Verrasttechniken, a particularly simple attachment of the housing on Carrier element allows.

In a particularly preferred, because material-economical embodiment of the invention, the at least one receptacle on the support element is arranged, while the at least one connecting element is arranged on the housing.

An inventive attachment of the housing on the support element is reversible, so that in case of need a simple and quick disassembly of the housing can be done.

The connecting element can be fixed both by means of a linear movement, that is to say on a linear path or else by means of a rotational movement, that is to say on a rotational or circular path in the receptacle. The selection as to whether a linear or translatory or rotationally carried out definition of the / the connecting elements (s) should take place in its / its end position, can be made depending on the existing geometry of the housing and the carrier element or the cooling device.

In particular, a rotational fixing of the connecting element (s) in the corresponding receptacle (s) ensures a stable and vibration-resistant hold of the housing on the support element. By the housing is convertible by means of a rotational movement from the mounting position to the operating position, a short and effective mounting movement is made possible.

In a particularly preferred embodiment of the invention, the receptacle has a first receiving portion, in which a threading of the connecting element into the receptacle is possible and a second receiving portion, in which the latching or clamping of the connecting element takes place. The clear width of the first receiving portion is preferably made larger than the clear width of the second receiving portion. In this way, an exact attachment and precise guidance of the connecting element in the receptacle is made possible.

In a special embodiment of the invention, the clear width of the receptacle between the first receiving section and the second receiving section is reduced linearly. In this way, a suitable for clamping the connecting element recording is made.

In a further specific embodiment variant of the invention, it is provided that the clear width of the receptacle first decreases during the transition from the first receiving section to the second receiving section and then extended. In this way, a suitable for locking the connecting element recording is made.

In a manufacturing technology advantageous embodiment of the invention, each recording consists of two overlapping circular openings.

In a particularly preferred embodiment variant, the connecting element has a shaft section which can be received by the receiving sections of the receptacle and a foot section adjacent thereto. The foot portion is further located to the housing than the shaft portion. Here, the clear width of the first receiving portion is greater than the largest cross-sectional width of the foot portion (and thus easy insertion or a Hindurchstecken the foot portion through the first receiving portion allows), while the clear width of the second receiving portion is smaller than the largest cross-sectional width of the foot portion.

Such an embodiment of the connecting device allows for easy insertion of the connecting element in the first receiving portion of the receptacle, wherein the

Connecting element subsequently by means of a linear or rotary movement in one of the operating position of the

Housing corresponding end position in the second receiving portion is conveyed. Because the biggest

Section width of the foot section is greater than the clear

Width of the second receiving portion, on reaching this end position no lifting of the housing from the support element is more possible and the housing is fixed to the support element.

With regard to a dimensioning of the receptacle passing through the shaft portion, there are several possibilities. In a first embodiment, it is provided that the largest cross-sectional width of the shaft portion is dimensioned smaller than the clear width of the second receiving portion. In such a case of execution, there is thus a play between the jacket of the shaft section and the boundary of the second receiving section and the shaft section or the connecting element can easily be moved within the receptacle.

Alternatively, the largest cross-sectional width of the shaft portion may be made smaller than the clear width of the first receiving portion (in which the shaft portion and the connecting element is used in the first mounting position of the housing), but the largest cross-sectional width of the shaft portion is greater than a first fit dimension the clear width of the second receiving portion. Thus, if the connecting element according to this configuration is conveyed to its end position in the second receiving section, then a pressing takes place between the second receiving section and the shaft section of the connecting element. In this way, an unintentional return of the connecting element is prevented against the mounting direction to its original position. In particular, can be prevented in this way that the connecting element dissolves due to operational vibration of the refrigerant compressor from its predetermined end position.

A particularly reliable fixing of the connecting element in its end position is made possible by at least the shaft portion of the connecting element is made in a preferred embodiment of an elastically or plastically deformable material. A

Compression of the elastically or plastically deformable shaft portion during its transport to the final position secures the connecting element against being returned to its starting position.

A further improvement of the erf indungsgemaßen connection device is made possible by the recording has a disposed between the first receiving portion and the second receiving portion third receiving portion, the clear width is smaller than the clear width of the second receiving portion and wherein the clear width of the third receiving portion of the other order a second fitting dimension is smaller than the largest cross-sectional width of the shaft portion. Thus, by providing a waisted passage in the form of the third receiving portion between the first and second receiving portion, which the shaft portion must pass during its transport into the end position, the connecting element can be securely locked in its end position or in the operating position of the housing.

In a particularly preferred embodiment of the invention, the first receiving portion and the second receiving portion in the form of two keyhole-shaped merging, i. formed in the region of a peripheral segment merging through holes in the carrier element. A receptacle designed in this way is easy to manufacture in terms of production technology and enables exact fixing of the connecting element on the support element.

In a further manufacturing technology advantageous embodiment of the invention, the shaft portion and the foot portion of the connecting element are made as separate components, wherein the shaft portion has a passage opening through which a on the housing fastened, preferably bolt-shaped adapter portion of the foot portion is passed.

In a further preferred embodiment of the invention, the shaft portion has a spacer portion which is arranged in the operating position of the housing between the housing and the support member, wherein the largest cross-sectional width of the spacer portion both greater than the clear width of the first receiving portion and larger than the clear width of the second receiving section. In particular, if this spacer portion is made of a vibration-damping material, a vibration transfer from the housing to the support member can be prevented or at least steamed.

In order to achieve a further protection of the erf mdungsgemaßen connection device against unwanted loosening, it is provided in a preferred embodiment that measured between the spacer portion and the foot portion distance is smaller by a third Maßungsmaß the thickness of the receiving portions having portion of the support member.

As already mentioned, the connecting element can be both by means of a linear movement, so also by means of a

Rotational motion, are set in the recording. In the latter case, the trajectory of the

Connecting element not necessarily have a circular arc shape, but can also be an arbitrarily curved, e.g. parabolic shape, which depending on

Use case simpler or more flexible assembly can allow.

In a further preferred embodiment of the invention are at least two, preferably three shots provided with corresponding connecting elements. The provision of at least two receptacles or Verbmdungselementen allows a very stable attachment of the housing to the support element. In particular, under Providence of three shots or fasteners is offered in terms of their static certainty particularly balanced mounting option.

In a special embodiment variant of the invention, the receptacles are offset along a partial circle, preferably offset from one another equidistant from one another, arranged on the support element. This allows easy installation and a balanced weight distribution of the housing on the support element.

As a preferred embodiment of a determination of the connecting element in the corresponding receptacle along a linear path, it is provided that the support element has a retaining portion forming the second receiving portion, which is increased relative to a housing assigning top of the support element, wherein the foot portion of the connecting element with a from the Housing remote end face (during the carriage of the connecting element in its end position) on the upper side of the carrier element slidably and can be converted into the retaining lip.

Here, it is provided in a development of the invention that the support member has a suspension portion which is verdrangbar during a transfer of the fastener foot portion in the retaining lip from an unloaded position to a holding position in which the connecting element is fixed in the receptacle. By Providence of such a suspension section is an undesirable loosening of the connecting element of his End position (in which the housing is fixed in operating position) safely prevented.

In a particularly preferred embodiment, it is provided that the suspension section rises in its unloaded position on the top of the support element and contacted in its holding position, the end face of the connecting element foot section at least in sections. As a result of the pressure effect of the suspension section on the foot section-which is thus held in a clamping manner between the retaining lip and the suspension section-unwanted release of the connection element from its end position (in which the housing is fixed in the operating position) can be prevented.

In a production technology particularly easy to implement embodiment of the suspension portion is formed in the form of a piece integral with the support member web, which is preferably bent in the direction of the housing to be fastened to the support member housing.

WAYS OF IMPLEMENTING THE INVENTION

Fig.l shows a refrigerant compressor with a hermetically sealed housing 2, which is set in erf indungsgemaßer manner on a support element 1.

The carrier element 1 which is plate-shaped in the present exemplary embodiment is part of a refrigerator or a container enclosing a cooling volume, and e.g. arranged in the bottom or the rear wall area. The

Carrier element 1 has a housing 2 zuweisende

Top 17 and a repellent from the housing 2 bottom 18.

The housing 2 is made in two parts in the present embodiment and comprises a lower half Gehausehalfte 2a and a Gehachenehalfte 2b. Inside 7 of the housing 2 is a working unit in the form of a by means of an electric motor arranged driven piston-cylinder unit which compresses a transported via inlets and outlets refrigerant in a known manner. To accommodate the supply and discharge lines, the housing 2 has various openings 9. Since the components arranged in the interior 7 of the housing 2 and their connection to the inlets and outlets leading to an evaporator and a condenser of the cooling appliance are not relevant for the understanding of the present invention, their illustration has been omitted.

The housing 2 can be fastened by means of a erf mdungsgemaßen connection device 10 on the support element 1, which comprises at least one arranged on the housing 2 connecting element 3, which is at least one corresponding, provided on the support element 1 receptacle 4 by clamping or latching fixed.

Alternatively, it would also be possible to arrange the at least one connecting element 3 on the support element 1 of the cooling device and the at least one receptacle 4 on the housing 2, e.g. in that a plate 4 having the receptacles 4 is attached to the housing 2 (not shown).

According to the present exemplary embodiment, the support element 1 has at least three receptacles 4, while the housing 2 is provided with three corresponding connecting elements 3 which can be inserted into the receptacles 4.

However, it would also be possible to provide a different number of receptacles 4 or connecting elements 3, e.g. two or four

Admissions 4 / connecting elements 3. The provision of only one receptacle 4 and, for example, a centrally arranged at the bottom of the lower housing part 2a connecting element 3 would be conceivable. As can be seen in a single representation of the erf indungsgemaßen carrier element 1 according to Figure 2, the receptacles 4 along a pitch circle 11 are arranged offset. The receptacles 4 are each offset by 120 ° to each other, so that an equidistant arrangement of the images 4 results to each other.

Corresponding to the position of the receptacles 4 on the carrier element 1, the connecting elements 3 are arranged on the housing 2. The connecting elements 3 are arranged along a (not shown) pitch circle equidistant from each other.

In Figure 3 is a detailed representation of a recording 4 can be seen, which in the form of two different sizes

Through holes 15, 16 are formed by the support member 1. The centers of the holes 15, 16 are each arranged on the pitch circle 11, wherein the two

Drill holes 15, 16 in the region of a bore peripheral segment merge together, so that the recording 4 a in

Has substantially keyhole-shaped boundary.

The first bore 15 corresponds to a first receiving portion 4 a of the receptacle 4, while the second bore 16 corresponds to a second receiving portion 4 a of the receptacle 4.

In other words, the cross sections of the first receiving portion 4a and the second receiving portion 4b are formed in the form of two overlapping circular shapes or openings.

The receiving portions 4a, 4b of the receptacle 4 may of course also have a different geometric shape than shown in the present embodiment, only essential is that receptacle 4 has a first portion which is suitable for receiving or for passing the arranged on the housing 2 connecting element 3, and a narrowing with respect to this first section second section.

According to Figure 3, the clear width 4a 'of the first receiving portion 4a is greater than the clear width 4b' of the second receiving portion 4b.

The manner of attachment of the connecting element 3 on the support element 1 is understood in consideration of Figure 5, which shows a detail of a side view of the refrigerant compressor according to Figure 4, understood. The lower housing half 2a has a plurality of - in the present embodiment, three bulges 8, on which the already mentioned Verbmdungselemente 3 arranged, for. welded or screwed. Also, a one-piece design of the connecting elements 3 with the housing 2 is possible.

The connecting element 3 has a shaft section 5 adjoining the housing 2 and a foot section 6 arranged in an end region of the shaft section 5 facing away from the housing 2, the shaft section 5 and the foot section 6 having a cylindrical shape or disk shape.

The first receiving portion 4a has a drawn in Figure 3 clear width 4a '(which in the present

Embodiment corresponds to the diameter of the first bore 15), which is greater than the largest

Cross-sectional width 6 'and the diameter of the drawn in Figure 5 foot section 6. In this way, a problem-free recording or a bottom even closer described Passing the foot portion 6 through the first receiving portion 4a allows.

A clear width 4b 'of the second receiving portion 4b and the diameter of the second

Bore 16, in contrast, is smaller than the cross-sectional width 6 'or the diameter of the foot section 6.

The largest cross-sectional width 5 'of the shank portion 5 drawn in FIG. 5 is selected such that the shank portion 5 can be moved under manual application of force without difficulty both in the first receiving portion 4a and in the second receiving portion 4b.

Regardless of the specific geometric configuration of the receptacle 4, the first receiving portion 4 a each allow threading of the Verbmdungselementes 3 in the receptacle 4.

An assembly of the housing 2 on the support element 1 is carried out in the following manner:

First, the housing 2 is brought into a position in which the connecting elements 3 above the first

Receiving section 4a are located (in the present

Embodiment here is aligned with the longitudinal axis 20 of the

Connecting element 3 with the axis of the first

Bore 15). Then threading of the foot section 6 takes place in the receptacle 4 in a first mounting direction 14 (first mounting movement) shown in FIG. 1 and FIG. The first

Mounting direction 14 extends in the axial direction of the

Verbmdungselemente 3 or substantially normal to

Top 17 of the carrier element. 1 Once the connecting elements 3 are threaded into the corresponding first receiving portions 4a of the receptacles 4, the housing 2 is in a first mounting position.

As a result, the housing 2, together with the connecting elements 3, following a second mounting direction 19, is rotated into an operating position (second assembly movement - see also FIG. 2). The second mounting direction 19 extends substantially normal to the first mounting direction 14 and substantially parallel to the top 17 of the carrier element 1 (which is arranged horizontally in the present embodiment). The second assembly direction 19 further extends substantially normal to the longitudinal axis 20 of the connecting element 3. Looking from a bird's eye view of the arrangement shown in Fig.l, so a rotation of the housing 2 is completed in a clockwise direction.

During this second assembly movement, the connecting elements 3 are conveyed from a starting position in which the longitudinal axes 20 of the connecting elements 3 are located within the first receiving section 4a to an end position in which the longitudinal axes 20 of the connecting elements 3 are located within the second receiving section 4b. When the connecting elements 3 have been conveyed to their final position, the housing 2 is also in its operating position and is fixed therein on the support element 1 (see also FIG. 6).

Since the clear width 4b 'of the second receiving section 4b or the diameter of the second bore 16 is made smaller than the largest cross-sectional width 6' or the diameter of the foot section 6, the foot section 6 ensures that during the second assembly movement is moved to its final position, the housing 2 against lifting from the support element. 1

As can be seen in Figure 3, the receptacle 4 has a arranged between the first receiving portion 4 and the second receiving portion 4b third receiving portion 4c, the clear width 4c 'is smaller than the clear width 4b' of the second receiving portion 4b, wherein the clear width 4c 'of this third receiving portion 4c is further smaller than the cross-sectional width 5' of the shaft portion 5, as shown in Fig. 3. As shown in Fig. 3, those portions are where the two receiving portions 4a and 4b merge and in which the third receiving portion 4c is located is provided with curves 12 to allow an ideal conveying the shaft portion 5 in its final position.

During its transport from the starting position to its end position, therefore, the shaft section 5 of the connecting element 3 must pass through a waisted passage in the form of the third receiving section 4c. After one of the second mounting direction 19 subsequent passing of the third receiving portion 4c of the shaft portion 5 of the connecting element 3 and thus the entire housing 3 is prevented from moving back against the second mounting direction 19. Since the Verbmdungselement 3 is now securely clamped in its final position or locked, a particularly effective protection against turning back of the housing 3 is achieved in its first mounting position.

If the connecting element 3 is required to return to its starting position or the housing 3 is released from its operating position in the course of disassembly, then it must be Movement cycle against the previously described second and first mounting direction 19 and 14 done.

The cross-sectional width 5 'of the shaft portion 5 can be configured in different ways.

Thus, it is provided in a first embodiment that the (largest) cross-sectional width 5 'of the shaft portion 5 is dimensioned smaller than the clear width 4b' of the second receiving portion 4b. In such a case of execution, there is thus a play between the jacket of the shaft section 5 and the boundary of the second receiving section 4b, and the shaft section 5 or the connecting element 3 can be moved with ease within the entire receptacle 4 (unless the clear width 4c 'of the third Receiving portion 4c is selected smaller than the largest cross-sectional width 5 'of the shaft portion 5).

Alternatively, the cross-sectional width 5 'of the shaft portion 5 may be made smaller in a second embodiment than the clear width 4a' of the first receiving portion 4a, but the cross-sectional width 5 'of the shaft portion 5 is made larger by a first fit dimension than the clear width 4b 'of the second receiving portion 4b. If, therefore, the connecting element 3 according to the second embodiment is conveyed to its end position in the second receiving section 4b, then a pressing takes place between the second receiving section 4b and the shaft section of the connecting element or a clear resistance is opposed to the second mounting movement in the mounting direction 19. Connecting element 3 According to the second embodiment variant of the connecting element shaft section 5, an unintentional or vibration-related return movement of the connecting element 3 prevented in its initial position against the second mounting direction 19.

It should be noted that the widths 4a ', 4b', 4c 'and 5' of the receptacle 4 and of the connecting element 3 are always measured orthogonal to the path along which the connecting element 3 is guided during the second assembly movement. Also in the event that the erfmdungsgemaße recording 4 not as

Bore or is made of circular sections, but has a different geometry, so are always those orthogonal to the second mounting direction 19 measured

Opening dimensions of the intake 4 relevant.

Since the receiving sections 4a, 4b can each have any desired geometric shape or can have a continuous or discontinuous width course along the respective movement path of the connecting element 3, the clear width 4a 'of the first receiving section 4a is understood to mean that width of the first receiving section 4a the connecting element 3 can be positioned in its initial position (and the housing 3 in its first mounting position), while the clear width 4b 'of the second receiving section 4b is understood to be that width of the second receiving section 4b on which the connecting element 3 is in its end position (and the housing 3 in its operating position) is positionable. Of course, in this context, the cross-sectional widths of the connecting element 3 or of the shaft section 5, the foot section 6 and the spacer section 5a are to be understood as the largest cross-sectional widths of these component sections which are guided in the receiving sections 4a, 4b during the assembly movements. The shank portion 5 of the connecting element 3 is made in a preferred embodiment of the invention of an elastically or plastically deformable material. In particular, when the connecting element shaft portion 5 is designed according to the described second embodiment and is therefore compressed during its transport into its end position in the receptacle 4 and in the second receiving portion 4b, a reliable fixing of the connecting element 3 in its end position and thus of the housing 2 are enabled in its operating position. A secure fixing of the connecting element 3 is ensured, in particular, if the shaft section 6 is made of an elastically deformable material, since such an elastic shaft section 6 is briefly compressed during the passage of the third receiving section 4c and then completely in its end position in the second receiving section 4b or partially relax to its original size.

Of course, the entire connecting element 3 together with the foot section 6 may be made of an elastically or plastically deformable material.

The shank portion 5 may be made in one piece with the foot portion 6 of the connecting element 3. In a preferred embodiment according to Figure 5, however, are the

Shank portion 5 and the foot portion 6 of

Connecting element 3 manufactured as separate components, wherein the shaft portion 5 has a through hole 13 through which a fastened to the housing 2, bolt-shaped

Adapter portion 6a of the foot section 6 is passed.

In a further preferred embodiment variant of

Invention, the shaft portion 5 of the connecting element 3 is provided with a spacer portion 5a. The example cylindrical formed distance portion 5a contacted with a first end faces the top 17 of the support element 1, while he arranged with a second end face the bulges 8 of the so between the housing 2 and the support member 1 and these distanced from each other. Here, the largest cross-sectional width of the spacer portion 5a and its diameter is both greater than the clear width 4a 'of the first receiving portion 4a and larger than the clear width 4b' of the second receiving portion 4b configured.

The spacer portion 5a is preferably made of a vibration damping material, e.g. made of rubber or other plastic to prevent vibration transfer from the housing 2 to the support member 1.

Of course, the spacer portion 5a does not need to be integrally formed with the shank portion of the connecting member 3, as shown in the present embodiment, but may be made as a separate member.

In order to achieve a further protection of the connecting device 10 against unwanted loosening, it can be provided that the underside of the spacer section 5a facing one of the top side 17 of the carrier element 1 and a top side of the foot section 6 facing the underside 18 of the carrier element 1 measured distance 22 The thickness of the region of the carrier element 1 which has the receiving portions 4a, 4b is smaller by a third measure of fit.

From the previously described geometry of the erf mdungsgemaßen recordings 4 shows that it is in the second assembly movement of the connecting elements 3 along the second mounting direction 19 is a rotational movement (see Figures 2 and 3). The center of this rotational movement or arcuate path would be to think in a center of the pitch circle 11. The rotational path along which each of the connecting elements 3 is moved thus extends from the center of the first bore 15 or the first receiving section 4a to the center of the second bore 16 and the second receiving section 4b, respectively.

Instead of a circular arc-shaped path, which performs the connecting element 3 during the second assembly movement, it would of course also be conceivable to use an arbitrarily curved, e.g. parabolic course or recording 4 provide.

Alternatively, however, it is also possible, the receptacles 4 on the carrier element 1 and the connecting elements 3 on the housing 2 to be arranged so that a linear path for fixing the

Connecting elements 3 is realized in the receptacles 4 or that the Verbmdungselemente 3 by means of a linear

Mounting movement in the receptacles 4 can be fixed (see Fig.7-11).

7 shows a preferred embodiment of a support element 1 with three receptacles 4, in which the connecting elements 3, following a linear movement path, can be fixed. Here, the support element 1 in the region of each receptacle 4 on the second receiving portion 4b forming retaining lip 23.

This retaining lip 23, which is embodied essentially in the form of an open half-shell in the present exemplary embodiment, is raised in relation to the upper side 17 of the support element 1 facing the housing 2. The retaining lip 23 is emstuckig executed in the present embodiment with the support member 1, wherein the increase in Retaining lip 23 is made over the top 17 of the carrier element 1, for example, by a deep drawing method.

The illustration according to FIG. 7 will be better understood if a sectional illustration shown in FIG. 9 is considered.

Fig. 9 shows a vertically through the invention

Connecting device 10 extending section according to

Section A-A in Figure 8, wherein the

Connecting element 3 is already in its fixed end position in the receptacle 4.

The foot portion 6 of the Verbmdungselementes 3 is slidable with a facing away from the housing 2 end face 25 on the upper side 17 of the support member 1 and is first (together with the housing 2) positioned in the region of the drawn in Figure 7 first receiving portion 4a. This positioning can be carried out in the course of a first assembly movement of the connecting element 3 taking place in a first mounting direction 14. In contrast to the recordings 4 described with reference to FIG. 2, the receptacles 4 according to FIG. 7 are open or have no closed circumferential contour. Although formed by the retaining lip 23 second receiving portion 4b in the embodiment of Figure 7 again designed as a bore, but this hole or the second receiving portion 4b is open.

Two end faces 23a, 23b pointing in the direction of the first receiving section 4a are provided on the retaining lip 23, which are first contacted by the shaft section 5 of the connecting element 3 moved along the linear second mounting direction 19 during a second assembly movement and then passed before the shaft section 5 or the connecting element 3 is conveyed to its end position in the second receiving portion 4b. The foot section 6 of the connecting element 3 slides with an end face 25 facing away from the housing during the entire second assembly movement along the second mounting direction 19 on the upper side 17 of the support element 1.

Specifically, the first receiving portion 4a of the receptacle 4 in this embodiment is defined only by the two end portions 23a, 23b of the holding lip 23, while the first receiving portion 4a is otherwise open. It should be noted that, of course, also in the embodiment according to the figures 1-6, an open receptacle 4 may be provided or this does not necessarily have to have a circumferentially closed on all sides.

The dimensioning possibilities of the receptacle 4 and the connecting element 3 already described with reference to FIGS. 1-6, in particular the dimensioning of the widths 4b ', 4c' and 5 'of the receptacle 4 or the shaft portion 5 shown in FIG. 7, are also in the embodiment according to FIG Figures 7-11 applicable.

In the embodiment according to FIGS. 7-11, the latching-enabling third receiving section 4c results in that region of the receptacle 4 in which the end sections 23a, 23b of the holding lip 23 open into the second receiving section 4b (see FIG Width of the second receiving portion 4b, in turn, the diameter of the second receiving portion 4b forming hole is measured.

To the foot portion 6 of the connecting element 3 and thus the

Set housing 2 securely on the support element 1, that is

Carrier element further provided with a suspension portion 24 (see plan view of Figure 7). Of the Suspension portion 24 is verdrangbar during a transfer of the fastener foot portion 6 in the retaining lip 23 from an unloaded position to a holding position in which the connecting element 3 is fixed in the receptacle 4.

Preferably, this suspension portion 24 rises in an unloaded position 26, as shown in a side view of Figure 12, over the top 17 of the support member 1 and is during attachment of the housing 2 on the support member 1 in the mounting direction 19 according to an engagement of the fastener foot section 6 displaceable in the retaining lip 23 in a cocked position 27 (the cocked position 27 corresponds in this case the holding position of the suspension portion 24). If the connecting element foot section 6 has been transferred into the retaining lip 23, then the end face 25 of the connecting element foot section 6 is contacted in sections by an end section of the suspension section 24 facing the receptacle 4 under tension and the connecting element foot section 6 between the retaining lip 23 and the suspension section 24 clamped. This has the consequence that the connecting element 3 is fixed in its end position in the receptacle 4 and thus the housing 2 in its operating position on the support element 1.

In the unloaded state 26, the suspension portion 24 can by a first angle OC of up to 45 ° relative to the

Top 17 of the support member 1 raise, while the suspension portion 24 m of its holding position or in the cocked position 27 by a second angle ß of up to 45 ° with respect to the top 17 in a direction away from the housing 2 bend (Fig.12) , The second angle β can also be approximately zero, so that the suspension section 24 in its cocked position 27 is substantially in a plane with the support member.

In a preferred embodiment, the suspension portion 24 is formed in the form of a web integral with the carrier element 1. This web can be bent in the direction of the housing 2 to be fastened to the carrier element 1 (as shown in FIG. 12, unloaded state 26). Of course, the suspension section 24 can also be a separate component that can be attached to the carrier element 1.

As an alternative to a clamping contact of the end face 25 of the connecting element foot section 6 by the suspension section 24 located in its holding position, it is also possible for the foot section 6 to come to lie in its holding position next to the foot section 6 or next to the shaft section 5, wherein preferably a peripheral region the foot portion 6 or the shaft portion 5 of the connecting member 3 is contacted by an end portion of the suspension portion 24 (as shown in Fig.9). Again, the suspension portion 24, before it reaches its holding position, first of the foot portion 6 of the connecting element 3 from an unloaded position - in which the suspension portion 24 above or below, but preferably at the same height with the support element 1 is (the angle α and β in the latter case are thus approximately zero) - displaced into a tensioned position 27 (FIG. 12). However, the elastic portion 24 snaps back after completion of conveying the connecting element 3 in its final position from the tensioned position 27 due to elasticity back into a holding position in which the suspension section 24 again above or below, but preferably at the same height is located with the carrier element 1 (the angle OC and ß are in the latter case again almost zero).

It is understood that the retaining lip 23 overlaps the foot portion 6 of the connecting element 3 in each case so far that a reliable hold of the connecting element 3 in the receptacle 4 is ensured.

Instead of a described with reference to the present figures, latching fixing the connecting elements 3 in the receptacles 4 and a clamping fixing the Verbmdungselemente 3 in the receptacles 4 is possible by the receptacle 4, for example. along the second mounting direction 19 is linearly tapered and the shaft portions 5 of the connecting elements 3 during transport from its initial position to its end position successively in the receptacle 4 and in the second receiving portion 4b are clamped.
