Abstract

The connector has sliding sleeve (11) encompassing clamping sleeve in a work position and exerts force that is directed radially inwards in the position. Force induced from the sleeve (11) in the position to the clamping sleeve is redirected in axial force component which is introduced directly by the clamping sleeve into a clamping surface. A radial force component is introduced directly into a compensation surface of a mating plug.

Description

The invention relates to a coaxial connector and an associated mating connector according to the Obergebriff of claim 1.

Such a connector-mating connector combination is for example from EP 1 222 717 B1 known. In the known connector, a radial force is introduced by means of a biased in the radial direction of the clamping sleeve in the mating connector. This introduced radial force is diverted by an encircling and inclined to the longitudinal axis of the mating connector clamping surface in an axial force component. The known connector-mating connector combination therefore always requires an inclined to the longitudinal axis of the mating connector clamping surface to redirect the initially introduced radially force into an axial force component.

The invention has for its object to provide a connector of the type mentioned, with an outer conductor contact surface of the mating connector is axially clamped against an outer conductor contact surface of the connector, regardless of the formation of the clamping surface, ie even with a perpendicular to the longitudinal axis of the mating connector clamping surface.

This object is solved by the features of patent claim 1.

Advantageous embodiments of the invention are specified in the subclaims.

The invention is based on the idea, the Axialkraftkomponente directly from the clamping sleeve in the clamping surface of the mating connector to initiate and not first to initiate a radial force, which must then be redirected at the clamping surface in an axial force component.

Since the Axialkraftkomponente directly, that is, due to the shape of the clamping sleeve, is introduced by the clamping sleeve itself, in the clamping surface, a force redirection at the clamping surface, whereby the clamping surface can be perpendicular to the longitudinal axis of the mating connector is unnecessary. Due to the invention, it is no longer necessary to form the clamping surface inclined to the longitudinal axis of the mating connector.

In an embodiment of the invention is advantageously provided that of the clamping sleeve and a radial force component directly, that is directly initiated by the clamping sleeve in a compensation surface of the mating connector. As a result, all forces acting on the mating connector radial force components are compensated, so that even with an inclined formation of the clamping surface only an axial force component is introduced into this.

According to a preferred embodiment, the introduction of the Axialkraftkomponente of the clamping sleeve in the clamping surface takes place only by moving the sliding sleeve in the working position. This means that an axial force component is not automatically transmitted from the clamping sleeve to the clamping surface after the connector and the mating connector have been assembled. For this purpose, first the sliding sleeve must be moved to a working position, in which then a radial force is exerted on the clamping sleeve. As a result, the free end of the clamping sleeve is pressed axially in the direction of the clamping surface, whereby an axial force component is introduced directly from the clamping sleeve into the mating connector. It is according to an advantageous embodiment of the invention provided that the clamping sleeve is initially spaced from the clamping surface after merging of connectors and mating connector and moved only by moving the sliding sleeve in the working position in the direction clamping surface and clamped against the clamping surface in the axial direction.

In a further development of the invention is advantageously provided that the introduction of the radial force component in the compensation surface is carried out only by moving the sliding sleeve in the working position. In this case, the clamping sleeve is initially spaced from the compensation surface and is moved only by moving the sliding sleeve into the working position radially against the compensation surface.

Of course, it is also conceivable that the clamping sleeve is already biased in such a radial direction that a radial force component is already introduced directly into the compensation surface of the counterpart when the sliding sleeve is still in a standby position and has not been moved to the working position.

According to a preferred embodiment, the clamping surface is perpendicular to the longitudinal axis of the mating connector. In an embodiment of the invention is advantageously provided that the clamping surface is provided on an outside radially projecting rib of the mating connector and / or a radially inwardly facing recess of the mating connector. It is advantageous if the clamping surface and / or the compensation surface is formed circumferentially around the mating connector.

According to an advantageous embodiment of the invention, the clamping sleeve is formed such that it extends from the connector or extends from the frontal opening of the connector in the axial direction of the clamping surface of the mating connector over, wherein the end portion is angled in the direction of clamping surface or bent back. In this case, the end region of the clamping sleeve extends in particular at an acute angle to the longitudinal axis of the mating connector. In order to improve the clamping effect in the axial direction, it is advantageously provided that the clamping sleeve has a radially outwardly widening region, which is preferably arranged immediately adjacent to the bent end region.

In order to allow a radial movement of the clamping sleeve, the clamping sleeve is provided with axially extending slots, whereby locking tongues are formed. The locking tongues are connected together at one end by a circumferential ring section. Alternatively, the clamping sleeve consists of spaced apart, distributed over the circumference of the connector, extending in the axial direction, tension springs.

It is advantageously provided that the sliding sleeve engages around the clamping sleeve in a standby position in which the clamping sleeve does not introduce any axial force into the clamping surface. The sliding sleeve can therefore be moved axially between a ready position and a working position. Normally, the sliding sleeve is designed in such a way that, even in the ready position, one, albeit small, radial force is exerted on the clamping sleeve. However, the radial force introduced by the sliding sleeve into the clamping sleeve is sufficiently large only in the working position so that an axial force component is introduced into the clamping surface of the mating connector by the clamping sleeve.

Of course, the sliding sleeve can also be designed such that no force is exerted on the clamping sleeve of the sliding sleeve in the standby position.

It is advantageous if the clamping sleeve is received with its radially outermost, in particular end-side, region in a recess on the inner circumference of the sliding circumference. Advantageously, the recess has a radially tapered axial section, so that the sliding sleeve can be moved from the standby position axially into the working position.

An embodiment of the invention will be explained in more detail with reference to the drawings.

a schematic enlargement of a detail of Figure 3.

On the left side of Figure 1, a connector 1 is shown. The coaxial connector 1 has a housing 2 which is open at its front side and is penetrated by a channel 3. An inner conductor contact 4 is arranged in channel 3 and insulated by means of a sleeve-shaped insulator 5 relative to the plug housing 2. The plug housing 2 forms an outer conductor and has an annular circumferential outer conductor contact surface 6 in the opening on the front side. The insulating sleeve 5 is flush with this outer side contact surface 6 frontally.

Within the frontal opening of the connector 1, a projecting in the axial direction of the clamping sleeve 8 is fixed, which is pressed radially into the opening 7. The clamping sleeve 8 is provided with axial slots 10, whereby a plurality of resilient locking tongues 9 are formed.

Around the clamping sleeve 8 around a sliding sleeve 11 is arranged, which is limited axially displaceable in the axial direction. In Figures 1 and 2, the sliding sleeve 11 is in a standby position in which it exerts no force on the locking tongues 9.

The latching tongues 9 run starting from a circumferentially closed region axially and parallel to the longitudinal axis A of the connector 1. This is followed by an obliquely, radially outwardly widening region 12 connects. As can be seen in Figure 2, the locking tongues 9 are guided past with the widening portion 12 on a clamping surface 13 of a mating connector 14 in the axial direction. Immediately to the radially outwardly widening region 12 of the locking tongues 9, an angled in the direction of the end opening 7 area 15 of the locking tongues 9 connects. With this angled area 15, the locking tongues 9 are again returned axially in the direction of clamping surface 13 and radially in the direction of the longitudinal axis A of the mating connector 14. As can be seen, the last end piece of the latching tongues 9 is again bent over and runs radially outwards in order to form an enlarged contact surface on the clamping surface 13.

The mating connector 14 has an outer conductor in the form of a substantially cylindrical housing 16. At the front, the housing 16 has an annular peripheral outer conductor contact surface 17. In a continuous channel 18 of this housing 16 is an insulator 20, in which a conductor 19 is arranged. On the front side in the conductor 19, a socket 21 for receiving the axially opposite mating connector protruding inner conductor contact 4 of the connector 1 is provided.

In the embodiment shown, the clamping surface 13 is arranged on an outside radially projecting rib 22 of the mating connector 14, wherein the clamping surface 13 is orthogonal to the longitudinal axis A of the mating connector 14.

In Figure 2, the mating connector 14 is attached to the connector 1. For this purpose, the mating connector 14 has been inserted with its front end in the clamping sleeve 8 in the axial direction until the two contact surfaces 6 and 17 touch. The clamping sleeve 8 is stretched during the Aufsteckvorgang in the embodiment shown briefly resiliently in the radial direction. However, this is not necessarily the case. The distance of the detents 9 to each other can be dimensioned such that the mating connector 14 can be moved into the position shown in Figure 2, without the locking tongues 9 must be radially expanded. As mentioned, the sliding sleeve 11 in Figure 2 is in the ready position, in she surrounds all locking tongues 9. The locking tongues 9 are received with their radially outermost, end-side areas in a circumferential recess 24 on the inner circumference 25 of the sliding sleeve 11. The recess 24 is dimensioned such that no radial force is exerted on the clamping sleeve 8 by the sliding sleeve 11. The recess 24 has a narrowing axial section 26 in the radial direction. In the ready position shown in FIG. 2, the latching tongues 9 abut neither on the clamping surface 13 nor on a compensation surface 27 of the mating plug 14 extending parallel to the longitudinal axis A of the mating plug 14. There is therefore no force exerted by the locking tongues 9 on the mating connector 14.

In Figure 3, the sliding sleeve 11 is shown in a working position. For this purpose, the sliding sleeve 11 has been displaced axially from the position shown in Figure 2, retracted ready position in the direction mating connector 14. The axial movement is limited by an end provided on the sliding sleeve 11, circumferential and inwardly facing edge 28 which comes to a radially outwardly opposed surface 29 of the plug housing 2 to the plant.

During the axial movement of the sliding sleeve, the axial section 26 is displaced along the radially propagating axial section 12 of the latching tongues 9 until the radially outermost region of the latching tongues 9 comes to rest on the inner circumference 25 of the sliding sleeve running parallel to the longitudinal axis A. As a result, a radial force F _{R is} applied by the locking tongues 9, which generates an axial force component F _a in the spring tongues 9, which is introduced directly, ie directly, into the clamping surface 13 of the mating connector 14. As can be seen in Figure 3, the locking tongues 9 deform in the working position of Sliding sleeve 11 such that the originally creased course of the locking tongues is almost smoothed.

In Figure 4, the force profile of the working position shown in Figure 3 is shown schematically with reference to a latching tongue 9. As explained, a radial force F _{R is introduced} into the locking tongues 9 by the sliding sleeve 11 in the working position. As a result, an axial force component F _a and a radial force component F _r are already produced in the latching tongues 9. The Axialkraftkomponente F _a is introduced directly from the free ends of the locking tongues 9 in the perpendicular to the longitudinal axis A of the mating connector 14 extending clamping surface 13 and generates there a counterforce F _{a '} . The radial force component F _r is introduced directly from the free ends of the locking tongues 9 into a, around the mating connector 14 and parallel to the longitudinal axis A of the mating connector extending compensation surface 27 and generates there a counterforce or compensation force F _{r '} . In contrast to the embodiment shown schematically in Figure 4, the free ends of the locking tongues 9 of course also rest flat against the clamping surface and / or the compensation surface 27.

Because all radial force components F _{r are} compensated for on the compensation surface 27, only an axial force component F _{a is} introduced into the clamping surface 13, even if the clamping surface 13 should be inclined relative to the longitudinal axis A of the mating connector 14.
