Description

The invention relates to a compressor, in particular a scroll compressor or reciprocating compressor, according to the preamble of claim 1. Furthermore, the invention relates to a vehicle air conditioning system with such a compressor and a manufacturing method. A compressor of the type mentioned is, for example DE 10 2012 204 703 A1 known.

DE 10 2012 204 703 A1 describes a compressor with an electric motor which is arranged in a pump chamber of a housing. The housing also has a receiving space for a control electronics, which is separated from the pump space by a bottom of the housing. For electrical connection of the control electronics with the electric motor, the bottom has an opening for the passage of electrical connection cable. In order to prevent coolant, which flows through the pump chamber, entering the receiving space for the control electronics, a sealing element is arranged in the opening of the bottom.

The guided in the pump chamber electrical cables are contacted by means of a connector with the cables of the electric motor, wherein the connector is laterally attached to a stator of the electric motor. In particular, the connector has a hook-like insertion piece, which engages in an L-shaped opening on the outer circumference of the stator. This arrangement is intended to help that coolant flowing through the pump chamber is also conducted along the bottom, so as to cool over the bottom the control electronics arranged in the opposite receiving space.

A disadvantage of the known compressor, however, is that a high production cost is required to form the L-shaped insertion opening in the laminated stator core. The individual sheets of the stator lamination stack have different punched holes for forming the L-shaped insertion opening and must be arranged one above the other in the correct sequence and orientation. This increases the assembly effort. When mounting the electric motor in the housing, the electrical contacting must first be made manually before the electric motor can be inserted into the housing. Also in terms of design, the arrangement of the connector on the circumference of the stator has disadvantages. Because the flowing through the pump chamber coolant must be guided along the stator to get into the compression section. The arranged at the periphery connector is so far a flow obstacle.

The object of the invention is to provide a compressor, in particular a scroll compressor or reciprocating compressor, which enables a simplified manufacture and assembly. It is another object of the invention to provide a vehicle air conditioning system with such a compressor and a manufacturing method.

According to the invention this object is achieved with regard to the compressor by the subject-matter of claim 1, with regard to the vehicle air conditioner by the subject-matter of claim 14 and with regard to the method by the subject-matter of claim 15.

Specifically, this object is achieved by a compressor, in particular scroll compressor or reciprocating compressor, having a housing which limits a pump space. The compressor further includes an electric motor with a stator and a connector for electrically connecting a control electronics with the electric motor. The electric motor and the connector are arranged in the pump room. The connector has a front side with at least one pin, which is insertable for mechanical connection with the stator in at least one front-side mounting opening of the stator. In particular, the pin can be arranged in the frontal mounting opening or inserted therein.

In the present invention, the connector is therefore arranged on an end face of the stator or of the electric motor. In this case, the end face of the stator is preferably aligned so that it faces a bottom of the housing in the installed state of the electric motor. The connector is arranged by the frontal arrangement outside the flow area of the pumping medium, in particular a coolant. In that regard, the connector hardly affects the flow of the coolant. The frontal arrangement also makes it possible for the electric motor, at least in any case the stator, and the plug connector to be preassembled as an assembly. The front-side connector can then engage directly in a passage opening of the bottom of the housing, so that a temporally upstream contacting of electrical cables within the pump chamber can be omitted during assembly of the electric motor.

The frontal mounting opening is, in particular compared to the L-shaped, lateral insertion opening from the prior art, easy to manufacture. For example, the attachment opening may be formed by a bore. In any case, it is sufficient if the frontal mounting opening is a straight, aligned parallel to the stator axis opening into which the pin can be inserted. In this respect, the compressor according to the invention is easy to manufacture and assemble.

In a preferred embodiment of the compressor according to the invention, the pin has a plug-in section and a support section. The support portion may have a larger cross-sectional area than the insertion portion. In the assembled state, the support section is preferably located on windings of the stator. By the support portion, the connector is supported radially or on the circumference of the electric motor. This gives the connector increased stability and serves for the radial alignment of the connector. This has advantages in mounting the electric motor in the housing. The support portion is disposed in the assembled state of the connector outside the front-side mounting opening of the stator and exposed to the flow of the coolant. The support portion can therefore be shaped so that the pin in the region of the support portion has a flow-influencing effect. For example, the support portion may substantially have an oval or flat cross-sectional contour, which is rounded at the narrow sides.

The support portion may form a stop that limits the insertion portion. Preferably, the stop is formed by the larger cross-sectional area of the support portion. The support portion thus forms substantially a spacer, which defines the distance between the front of the connector and the end face of the stator. At the same time causes the stop which rests against the end face of the stator that a power transmission from the stator to the connector can be made to introduce the connector into a corresponding receiving opening of the bottom of the housing can.

With regard to the aim of enabling a simplified assembly of the compressor, it is preferably provided that the plug connector has a rear side, on which fastening elements are provided. The fasteners may cooperate with complementary receptacles for connection to the housing. In other words, the housing may comprise receiving elements which are connectable to the fastening elements of the connector. The design of the fasteners and the receiving elements is essentially arbitrary. For example, may be provided as fasteners on the connector threaded bolt or threadless bolt. The threaded bolts and the non-threaded bolts may cooperate with receiving elements of the housing, which are formed as through-holes in a bottom of the housing. The fixation of the threaded bolts or the threadless bolts is then done by nuts, split pins or Seeger rings. Alternatively, the fasteners of the connector may be formed by threaded holes in the connector. The threaded holes each have an internal thread. The bottom of the housing may also have through holes in this design, can be passed through the screws as receiving elements. The screws are then inserted into the fasteners or tapped holes of the connector so that the connector can be firmly connected to the housing.

To ensure that the connector in the compressor according to the invention affects the flow of the pumping medium or coolant as little as possible, it is preferably provided that the front and the back of the connector are arranged substantially parallel to each other.

The housing may have a through opening that connects the pumping space to an electronics area. The connector may include a holding portion received in the through hole. The holding section allows in this respect a prefixing of the connector in the housing. This simplifies the installation of the compressor considerably. The connector and the stator or the entire electric motor can be pre-assembled as a unitary motor assembly. Thus, the electric motor equipped with the connector can be inserted as a unitary motor assembly in the housing, wherein the connector is inserted with its holding portion in the through hole of the housing. Thus, a prefixing and pre-positioning of the electric motor is achieved in the housing. Finally, the connector is then firmly fixed in the housing by means of the fastening elements and the receiving elements.

It is particularly preferred in this context if the holding portion forms a unitary component with the connector. In particular, the holding portion may be formed integrally with the connector.

In a further preferred embodiment of the compressor according to the invention it is provided that at least two, preferably three, electrically conductive connecting bolts are embedded in the connector, in particular in the holding section. The electrically conductive connecting bolts can protrude at least over the front side and / or over the rear side. The connector thus not only serves to mechanically pre-fix the electric motor in the housing, but also allows the electrical connection between the pump chamber and the electronics area. An additional passage of cables through a bottom of the housing is avoided in this way. This leads to a further simplification of the assembly of the compressor.

The connecting bolts may each have, at least on the front side of the connector, a crimping section with a longitudinal axial insertion opening for receiving electrical connection wires of the electric motor. Alternatively, the electrical contacting of the connecting wires to the connecting bolt can be done by ultrasonic welding, soldering, screw terminals or spring terminals. In any case, it is provided that the connecting bolts protrude in the assembled state on the one hand in the pump chamber and are electrically connected to the electrical connection wires of the electric motor. This connection may be made prior to assembly of the electric motor in the housing to form a unitary motor assembly. On the other hand, the connecting bolts in the electronics area can be electrically connected to connecting wires of control electronics. This connection can be made after mounting the electric motor in the housing.

For simplified positioning and insertion of the holding portion in the through hole of the housing is advantageously provided that the holding portion protrudes beyond the back of the connector and tapers with increasing distance from the back. In other words, the holding portion may be cone-shaped, frusto-conical or truncated pyramidal. The passage opening may have a correspondingly complementary shape.

In a further preferred embodiment of the compressor is provided that the holding portion of the connector has a rubberized surface which seals against the passage opening. At the same time, the connector assumes the function of a sealing element in order to seal the pump chamber from the electronics area. An outlet of the pumping medium or the coolant from the pump chamber is thus avoided.

A further sealing of the pump chamber can be achieved in that the connector, in particular the back, has a circumferential groove in which a seal is received. The circumferential groove preferably surrounds the holding portion. If the holding portion has a rubberized surface, the seal serves as a second barrier, whereby the sealing function of the connector is ensured with increased security. In this respect, it is preferably provided that the seal between the connector, in particular the back, and the housing is arranged and completely encloses the passage opening of the housing.

In the context of the present application also discloses a vehicle air conditioning system, in particular CO ₂ air conditioning, disclosed and claimed with a compressor mentioned above.

• – Einführen des Zapfens des Steckverbinders in die stirnseitige Befestigungsöffnung des Stators, wobei der Steckverbinder mit dem Stator zu einer einheitlich handhabbaren Motorbaugruppe verbunden wird, und Einsetzen der Motorbaugruppe in das Gehäuse.

A subsidiary aspect of the invention relates to a method for assembling a previously described compressor or a previously described vehicle air conditioning system, the method comprising the following steps:

• - Inserting the pin of the connector in the front-side mounting opening of the stator, wherein the connector is connected to the stator to a uniformly manageable motor assembly, and inserting the motor assembly into the housing.

The assembly method described here facilitates the production of the compressor, as can be dispensed with a complex electrical contacting within the pump chamber before the onset of the electric motor. Rather, the electrical contacts, in particular the connecting bolts, are guided directly through the through-opening of the housing by the plug connector, so that the electrical connection with the control electronics can subsequently be made from the outside or from the electronics area.

It is preferably provided that the holding section of the connector acts as a centering aid when the motor assembly is inserted into the housing. This eliminates a complex, positionally accurate alignment of the electric motor when inserted into the housing. Due to the self-centering of the section, therefore, the assembly is faster feasible.

The embodiment of a compressor described in the accompanying drawings relates in particular to a compressor used in vehicle air conditioners. The compressor is preferably configured such that CO ₂ can be used as the cooling medium of the vehicle air conditioner. Accordingly, the compressor is designed as a high pressure compressor. The illustrated embodiment particularly shows a scroll compressor in which the compression space is formed by two eccentrically rotating spirals. Alternatively, it is also possible to form the compressor described here as a reciprocating compressor.

Anyway, the compressor is powered by an electric motor 20 operated in a pump room 11 a housing 10 is arranged. The electric motor 20 has a stator 21 on. Inside the stator 21 a rotor is provided which, for reasons of clarity, is not shown in the attached drawings.

In general, the electric motor 20 preferably designed as a brushless DC motor. The stator 21 can be formed by a laminated core, with stator windings 22 is wrapped. The windings 22 are controlled separately from each other, the control is controlled by means of Hall sensors.

For controlling the electric motor 20 , in particular the individual windings 22 , serves a control electronics, outside the case 10 is arranged. In particular, the control electronics in an electronics field 12 arranged. The electronics area 12 is through a floor 13 of the housing 10 from the pump room 11 separated. Preferably, the control electronics is directly on the ground 13 arranged so that a heat coupling between the ground 13 and the control electronics consists. The electronics can thus indirectly over the ground 13 be cooled.

The connection between the electric motor 20 and the control electronics is preferably carried out by a connector 30 , The connector 30 It is designed to pre-position and pre-fix the motor assembly that is made from the electric motor 20 and the connector 30 is formed in the housing 10 serves. The connector 30 has two pins 33 on, in corresponding mounting holes 23 of the connector 30 intervention. The mounting holes 23 are on a front side 24 of the stator 21 arranged. In this respect, the connector 30 frontally on the stator 21 arranged.

As in 1 clearly recognizable, the connector points 30 a front side 31 on, from which the cones 33 out. The front 31 is the stator 21 facing. The connector 30 also has a back 32 in the mounted state of the motor assembly in the housing 10 on the ground 13 is applied. The cones 33 lie on an outer circumference of the windings 22 on. In other words, the connector 30 through the cones 33 on the windings 22 supported. Concretely, each pin comprises 33 a plug-in section 33a in the mounting holes 23 of the stator 21 is introduced. Furthermore, each pin has 33 a support section 33b on, on the windings 22 rests. For details on the design of the connector 30 will be discussed below in connection with 6 and 7 discussed in more detail.

In 2 is in detail a sectional view through the compressor according to 1 shown. It can be seen in the cross-section of the winding 22 on which the pad section 33b of the pin 33 rests. It can also be seen that the connector 30 at its front 31 connecting bolts 36 having. The connecting bolts 36 extend completely through the connector 30 and allow the electrical contact between the electric motor 20 and a control electronics. It can also be seen that the case 10 for receiving the connector 30 a corresponding housing bulge 17 having. The connector 30 engages in the housing bulge 17 essentially positively, so that by means of the connector 30 also a positionally accurate alignment of the motor assembly with the electric motor 20 and the connector 30 is possible.

Furthermore, the cross-sectional view according to FIG 2 that between the electric motor 20 , in particular the winding 22 and the housing 10 , an annular gap 18 is provided. The annular gap 18 is flowed through by coolant, so that the coolant from the bottom region of the housing 10 can flow in the direction of a compressor area. The coolant supply 16 discharges laterally into the annular gap 18 ,

The motor assembly with the electric motor 20 and the connector 30 can be provided pre-assembled. Such a preassembled motor assembly is exemplary in the 3 and 4 shown, was omitted for reasons of clarity on the representation of the rotor. Shown is the stator 21 who is at his forehead 24 two mounting holes 23 having. In the mounting holes 23 are cones 33 of the connector 30 introduced. The cones 33 include a plug-in section 33a that is completely in the mounting holes 23 is included. A support section 33b of the respective pin 33 is outside the mounting hole 23 arranged and lies on the winding 22 of the electric motor 20 on. The connector 30 is so radial with respect to the electric motor 20 supported.

In 3 is the back 32 of the connector 30 good to see. On the back side 32 is a holding section 34 educated. The holding section 34 is preferably integral with the connector 30 shaped. The holding section 34 sheathed three connecting bolts 36 for the electrical connection of the electric motor 20 serve with a control electronics. The connecting bolts 36 can each have a longitudinal axial insertion 36a have, in which connection wires or connecting wires can be inserted. For fixing the connecting wires or connecting wires in the insertion opening 36a has the connecting bolt 36 preferably a crimping section, in which the insertion opening 36a is trained. By means of a crimping tool, the respective connecting wire or connecting wire can then be inserted in the insertion opening 36a be fixed positively or non-positively.

The holding section 34 preferably carries three connecting bolts 36 extending completely through the connector 30 extend. This raises the holding section 34 starting from the back 32 of the connector 30 , wherein the holding section 34 preferably has a longitudinally tapered course. In particular, the holding section tapers 34 starting from the back 32 , The holding section 34 thus also serves as a centering aid for prefixing the connector 30 in the case 10 , Accordingly, the housing comprises 10 a passage opening 14 corresponding to the holding section 34 is formed tapering. The holding section 34 may have a rubberized surface against the passage opening 14 seal.

The connector 30 indicates on its back 32 also two threaded bolts 35 on, which serve as fasteners. The threaded bolts 35 are in corresponding receiving openings in the ground 13 of the housing 10 arranged. In particular, the threaded bolts pass through 35 the ground 13 of the housing 10 in the assembled state, leaving the threaded bolts 35 in the electronics sector 12 over the ground 13 protrude. So can the threaded bolts 35 from outside the pump room 11 be provided with nuts to the connector 30 or the entire motor assembly in the housing 10 to fix.

As in 3 Also clearly visible is the connector 30 overall kidney-shaped. The design of the connector 30 is specifically chosen so that the connector 30 the least possible influence on the flow of the coolant in the pump chamber 11 exercises. In this respect, at least the support sections 33b the pin 33 be designed flow optimizing. In particular, the support sections 33b formed substantially flat with rounded side surfaces. The support sections 33b have substantially an oval cross-sectional profile.

On the back side 32 of the connector 30 is a groove 37 formed the holding section 34 and the threaded bolts 35 or fasteners surrounds. In the groove 37 is a seal, in particular a rubber seal arranged. As in 1 well recognizable seals the seal 38 completely against the ground 13 of the housing 10 off, leaving the passage opening 14 of the housing 10 completely from the fluid flow in the pump room 11 disconnected.

In 4 is the front side 31 of the connector 30 recognizable. It can be seen that the connecting bolts 36 through the connector 30 extend through. The connecting bolts 36 are between the pins 33 arranged. In addition, from the synopsis of 3 and 4 recognizable that the connector 30 has a comparatively small thickness, in particular the front side 31 and the back 32 parallel, in particular plane-parallel, aligned with each other.

For fixing the connector 30 at the stator 21 of the electric motor 20 points the electric motor 20 the mounting holes 23 on. The mounting holes 23 are in 5 recognizable. The location of the mounting holes 23 decides on the correct positioning of the electric motor 20 in the case 10 , In this respect, the connector offers 30 in conjunction with the mounting holes 23 in the electric motor 20 the possibility of positioning the electric motor 20 or its correct orientation. This also serves to facilitate assembly of the motor assembly in the housing 10 ,

The details of the connector 30 are in the 6 and 7 good to see. 6 shows the back side 32 of the connector 30 , The backside 32 includes the holding section 34 and the threaded bolts 35 , which serve as fasteners. Furthermore, the back is 32 with the groove 37 provided the seal 38 wearing.

The front 31 , in the 7 is shown also includes the connecting bolt 36 , which completely through the connector 30 , Especially by the holding section 34 , pass through. Furthermore, at the front 31 the cones 33 arranged for connecting the connector 30 with the stator 21 of the electric motor 20 serve. The cones 33 each have a plug-in section 33a on, which is formed in the present embodiment as a round bolt. To the insertion section 33a closes a support section 33b on, which has a larger cross-sectional area than the insertion portion 33a having. The support section 33b is formed in particular flat oval, wherein the insertion portion 33a eccentric to the support section 33b is aligned. In 7 is also recognizable that the support sections 33b both cones 33 are angled at an angle to each other. The support sections 33b so follow the curvature of the winding 22 of the electric motor 20 ,

The support section 33b makes a stop 33c , in the assembled state of the connector 30 at the front 24 of the stator 21 is applied. The support section 33b acts in this respect because of the attack 33c as a spacer, the distance of the connector 30 or the front 31 of the connector 30 from the front side 24 of the stator 21 sets.

In the assembled state of the motor assembly with the electric motor 20 and the connector 30 in the case 10 as exemplified in 1 is shown, the connecting bolts protrude 36 and the threaded bolts 35 through the ground 13 through into the electronics area 12 , On the threaded bolts 35 then nuts can be screwed to the connector 30 and thus also the electric motor 20 in the case 10 to fix. By the screw fixation of the threaded bolt 35 also becomes the connector 30 against the ground 13 pressed so that the seal 38 the passage opening 14 can seal efficiently. Another seal is made via the holding section 34 passing through the screw connection of the connector 30 on the ground 13 also in the passage opening 14 is urged and so against the inner wall of the passage opening 14 seals. The connecting bolt 36 that's over the ground 13 in the electronics sector 12 projecting, can be easily achieved with a tool, so that an electrical connection between a control electronics and the connecting bolt 36 easy to produce.

An additional security for the sealing of the passage opening 14 is determined by the arrangement of the connector 30 in the pump room 11 reached. In the pump room 11 There is a comparatively high pressure during operation of the compressor, which also affects the connector 30 , especially its front 31 acts. This will make the connector 30 by the pressure of the coolant against the ground 13 pressed, reducing the effect of the seal 38 is increased. The coolant pressure in the pump room 11 causes in this respect an independent sealing of the connector 30 against the case 10 ,

The connector 30 may preferably be made in one piece from a plastic. In particular, the holding section 34 with the connector 30 integrally formed. The connecting bolts 36 or pins can be in the plastic of the connector 30 be poured directly. It is alternatively possible that the connecting bolts 36 an insulator, for example of glass or ceramic, have, in turn, directly into the connector 30 is poured.
