Description

The invention relates to a connector, in particular a high-current connector, with an inner conductor contact for current conduction, an outer conductor part and an inner conductor contact spaced from the outer conductor part holding insulator part, wherein an elastically compressible damping element is provided on the connector, that when inserting a complementary mating connector in the plug connector in an insertion direction is elastically compressible, according to the preamble of claim 1.

While the inner conductor contact is provided for current conduction, the outer conductor part may be in the form of a housing, such as an outer conductor housing, formed and / or grounded and thus shield the inner conductor. Such a coaxial connector is connectable to a coaxial cable, wherein the outer conductor of the coaxial cable is electrically contacted with the outer conductor portion of the connector, and an inner conductor of the coaxial cable is electrically contacted with the inner conductor contact of the connector.

Connectors generally serve to releasably connect electrical leads to carry power and / or electrical signals when connected. In this case, a first connector in the form of a socket part is verkuppelt with a second connector in the form of a plug part for forming a plug connection. High-current connectors are used to transmit high electrical currents, for example. With a current greater than 50 A or 100 A, and are the Example used in motor vehicles with electric drive or hybrid drive. In this case, the inner conductor contact of the mating connector having one or more in the insertion direction S projecting pins, which are inserted in the insertion direction in a receiving opening of the connector. In the receiving opening is the Innenleitkontakt the female part.

In order to prevent the inner conductor contact from coming into electrical contact with the outer conductor part, the inner conductor contact is regularly held by an insulator part made of a non-conductive material, such as plastic, the insulator part being arranged between the inner conductor contact and the outer conductor part. When assembling the connector, the insulator part is first attached to the inner conductor contact, for example. By means of a locking connection or other positive or non-positive connection, and then the assembly of insulator and inner conductor contact is attached to the outer conductor part, for example. Also by means of a locking connection or a other positive or non-positive connection.

However, it has been found that such a constructed connector tends to increase wear when it is exposed to high mechanical loads. For this reason, conventional high-current connectors must be regularly maintained, and components subject to wear, such as inner conductor contacts or insulating parts, must be replaced regularly.

From the DE 10 2011 004 347 A1 For example, an electrical connector for making a plug connection with a mating connector is known. The electrical connector includes a housing, a seal disposed on the housing, and a seal retainer disposed on the housing and associated with the seals. The seal holder is movably disposed on the housing to be moved in the direction of the seal and pressed against the seal in the manufacture of the connector with the mating connector. Due to the elastic stop a production-related movement space of the electrical connector can be reduced or eliminated at the mating connector, whereby the connector is less sensitive to mechanical influences, in particular vibrations. However, this only prevents a relative movement between the connector and the mating connector. Relative movements between an insulator part and an inner conductor contact or an outer conductor due to an existing axial play when inserting the mating connector can not be prevented hereby.

In view of the described problems, it is the object of the present invention to provide a connector suitable for transmitting high currents, which is subject to as little wear as possible under high mechanical loads, such as strong vibrations, and in this way to the durability of high current connectors increase.

This object is achieved by a connector of the above-mentioned. Art solved with the features indicated in claim 1 features 1. Advantageous developments of the invention are described in the dependent claims.

It is with a connector of o.g. Art according to the invention provided that the damping element during insertion of the mating connector directly or indirectly exerts pressure in the insertion on the inner conductor contact and / or pressure on the insulator part and thereby reduces mobility of the insulator member relative to the inner conductor contact and / or to the outer conductor part.

In other words, the damping element, for example. In the form of an elastically compressible soft component, provided on the connector so that it is compressed at a pressure acting on the plug-side end of the connector, while the inner conductor contact attenuated against the insulator part and / or the insulator part attenuated against the outer conductor part is pushed.

The invention is based on the knowledge that with conventional connectors manufacturing reasons regularly a considerable axial clearance between the inner conductor contact and the insulator part or between the insulator part and the outer conductor part is present. This axial play can lead to considerable relative movements of the insulator part with respect to the outer conductor part or with respect to the inner conductor contact under mechanical loads, such as vibrations, which causes the above-described increased wear of the connector.

It has already been attempted to limit this mobility of the insulator part in that the connection between the insulator part and the inner conductor contact and / or the outer conductor part is made more stable or stiffer. However, a very rigid and immovable connection between the insulator part and the inner conductor contact and / or the outer conductor part makes it difficult to quickly and easily mount the connector. In contrast, the insulator part of the connector according to the invention can have a predetermined axial mobility with respect to the outer conductor part and / or with respect to the inner conductor contact, so that a particularly simple and quick installation of the connector is possible. The observed wear causing mobility of the insulator part is inventively reduced only by the coupling of the mating connector with the connector and the associated axial pressure on the connector or completely eliminated. This is inventively achieved in that an elastic damping element is provided on the connector so that it is compressed during insertion of the mating connector due to the pressure exerted in the insertion direction, and thereby the insulator part, the inner conductor contact and / or the outer conductor part are compressed in the axial direction ,

The connector according to the invention can therefore be mounted quickly and easily and at the same time ensures a high stability and a good axial fixation of the insulator part between the inner conductor contact and the outer conductor part, so that vibrations originating from the outer conductor part can not lead to relative movements between the individual connector components.

In a preferred embodiment of the invention, the damping element exerts direct or indirect pressure in the insertion on the inner conductor contact and / or pressure on the insulator part when inserting the mating connector, so that the inner conductor part in the direction of the insulator part and / or the insulator part in the direction of the External conductor part is urged. Through the insertion of the mating connector of the connector is thus under damping by the elastic damping element compressed axially (in the insertion direction) and thereby restricted in its internal mobility.

Preferably, the connector with the mating connector cooperating positive and / or non-positive connection means such as screws, clamps or the like. on to sufficiently introduce the mating connector when plugging under compression of the damping element to the connector or to push sufficiently far into the connector can. In order to prevent excessive compression of the damping element by the connecting means, a corresponding stop may be provided on the connector.

It has proved to be expedient that the elastic damping element is not directly applied to a current-carrying element, such as the inner conductor contact. Rather, the damping element when inserting the mating connector should exert only indirectly pressure in the insertion direction on the inner conductor contact and thereby press axially against the insulator part. For this purpose, an axially movable intermediate element made of a rigid material may be provided between the damping element and the inner conductor contact. On the other hand, it has proved to be particularly advantageous that the damping element exerts immediate pressure in the insertion direction on the insulator part. In a particularly preferred embodiment of the invention, pressure is initially exerted indirectly on the inner conductor contact by the compression of the damping element in the plug-in direction, and pressure is additionally exerted indirectly and / or directly on the insulator part once a predetermined compression state of the damping element has been reached.

In order to enable such a stepped pressure application, it has proved expedient that an axial material thickness of the damping element is variably arranged, wherein a portion of high material thickness for applying pressure to the inner conductor contact and a portion of low material thickness provided for exerting pressure on the insulator part is. In this case, pressure is applied to the insulator part during the insertion process only when the damping element is already lower by the difference between the high-material-strength section and the section Material thickness is compressed. This leads to a particularly stable and rigid overall arrangement of connectors and associated mating connector. Preferably, the mating connector facing the front surface of the damping element has a convexly curved, in particular a rounded contour.

In the uncompressed state of the damping element, the connector according to the invention preferably has an axial clearance between the inner conductor contact and the insulator part and / or between the insulator part and the outer conductor part, wherein at least the clearance between the inner conductor contact and the insulator part, and preferably also the clearance between the insulator part and the outer conductor part can be reduced or eliminated by exerting pressure on the damping element in the insertion direction. A playful construction of the connector allows for easier and faster installation of the connector.

According to a particularly preferred embodiment of the invention, the damping element forms a counterpart connector when plugging facing front boundary surface of the connector. When inserting the mating connector then a counter-pressure surface of the mating connector can exert immediate pressure on the damping element.

A front mounted on the connector and preferably exposed to the environment damping element can still be attached to the connector after assembly of inner conductor contact and insulator part in the outer conductor housing. In particular, a subsequent retrofitting of conventional connectors by attaching the damping element is possibly still possible. Preferably, the damping element forms the leading during the insertion process interface of the connector.

With regard to a uniform and planar pressure exerted on the inner conductor contact and / or on the insulator part, it has proven to be advantageous for the damping element to rotate around an insertion opening of the connector for inserting a contact element of the mating connector. Preferably, the damping element is an annular soft rubber part or elastomer part.

In order to be able to exert reliable pressure on the arranged inside the connector inner conductor contact when plugging, it has proven to be expedient to provide a slider on the opposite side of the mating connector plugging side of the damping element, which is arranged axially displaceable along a guide of the connector and the axially behind the rear end of the inner conductor contact. The damping element then exerts during insertion of the mating connector indirectly via the sliding element as an intermediate element pressure on the inner conductor contact and urges the inner conductor contact in the direction of a contact surface of the insulator part.

The sliding element is preferably formed as a rigid, preferably at least partially annular plastic body, on the front end of the damping element is sprayed from an elastomer or rubber material.

Preferably, the insulator part has on its front side an at least partially annular guide groove whose groove bottom is formed by the inner conductor contact. The guide groove has a substantially axial course, so that the sliding element is axially displaceable therein, wherein it abuts against the inner conductor contact. The guide groove may have a holding mechanism, so that the sliding element is held axially displaceable in the guide groove and can not fall out. The holding mechanism may be formed in the form of a latching mechanism, wherein the sliding element may have a latching projection and the guide groove may have a latching recess or vice versa.

In the following, a second preferred embodiment of the invention will be explained. In this second embodiment, the elastically compressible damping element between the insulator part and the outer conductor part is arranged. When inserting the mating connector, the insulator part is pressed in the direction of the outer conductor part, whereby the damping element is compressed in the insertion direction, and thereby the mobility between the insulator part and the outer conductor part is limited.

With regard to a uniform pressure effect, it has proved to be expedient that the damping element has a substantially planar shape and is arranged between a substantially planar contact surface of the outer conductor part and a counter-pressure surface of the insulator part. In a cutting plane extending transversely to the insertion direction, a substantially round contour of the damping element has proved to be particularly advantageous. A more than one inner conductor contact exhibiting connector may also have more than one damping element.

Damage to the insulator part due to excessive pressure can be effectively prevented by variably setting the dimension of the damping element in the insertion direction S, wherein a central region of the damping element is thicker than an edge region of the damping element. As a result, upon insertion of the mating connector, first the central region and only then also the edge region of the damping element is compressed, so that the counter-pressure effect exerted by the damping element increases in the course of the insertion process. This facilitates the metering of a force for connecting connecting means, such as screws, provided for establishing the connection between the connector and the complementary mating connector.

The connector according to the second embodiment is preferably an angle connector in which a main axis H of the inner conductor contact and / or the insulator part extends transversely, in particular approximately perpendicular to the insertion direction, so that the current-carrying inner conductor can be led away transversely to the insertion direction of the mating connector. The inner conductor contact preferably has, on the one hand, a contact element for contacting the mating contact element of the mating connector and, on the other hand, a rod-shaped conductor part extending from the contact element along the main axis H, which can be connected to the inner conductor of a coaxial cable.

The damping element preferably has such a large dimension in the uncompressed state in the plugging direction that the inner conductor contact and / or the insulator part at least in sections by the damping element with respect Main axis is deflected. Only by inserting the mating connector of the inner conductor contact and / or the insulator part is fed back under compression of the damping element in an undeflected position in which the mobility of the inner conductor contact and / or the insulator part with respect to. The outer conductor part is limited.

According to a further aspect, the invention relates to a connector assembly having a connector according to the invention and a mating connector formed complementary thereto, which is configured such that when inserted into the connector, the damping element of the connector elastically compresses and thereby a mobility of the insulator member relative to the inner conductor contact and / or the outer conductor part is reduced.

an intermediate step in assembling the in Fig. 5 shown connector.

In Fig. 1 a first embodiment of a connector 10 according to the invention is shown in a longitudinal sectional view. The connector 10 consists of an inner conductor contact 20, which is circulated by an insulator part 30 made of a non-conductor, such as plastic. The insulator part 30 prevents the inner conductor contact 20 from coming into electrical contact with an outer conductor part 40 of the connector 10.

The connector 10 is connected to a coaxial cable 70, wherein the shield 71 of the coaxial cable 70 is electrically coupled to the outer conductor portion 40 of the connector and the inner conductor 72 of the coaxial cable 70 is electrically coupled to the inner conductor contact 20 of the connector 10, for example by soldering or crimping ,

The inner conductor contact 20 is plug-shaped as a socket formed with a contact spring into which a contact element 101 of a mating connector 100 in the form of a contact pin for making an electrical contact can be inserted. In the FIGS. 2a and 2b is the entire connector of connector 10 and associated mating connector 100 shown.

When assembling the connector 10, the inner conductor contact 20 is first connected to the inner conductor 72 of the coaxial cable 70, for example by soldering. Subsequently, the inner conductor contact 20 is inserted into the insulator part 30 until a projection of the insulator part 30 engages in a recess 25 of the inner conductor contact 20. The axial dimension of the recess 25 is set up such that a relative movement between insulator part 30 and inner conductor contact 20 within the framework of a predetermined axial play 21 is possible. This facilitates the attachment of the insulator part 30 to the inner conductor contact 20. Subsequently, the outer conductor part 40 of the connector 10, for example, by pressing or crimping attached to this cable assembly, so that the outer conductor part 40, the outer conductor 71 of the cable 70 electrically contacted. As part of a predetermined axial clearance 22, the outer conductor part 40 is movable relative to the insulator part 30.

The axial games 21, 22 allow for conventional connectors even after pairing with the complementary mating connector still relative movements between the inner conductor contact 20, the insulator part 30 and the outer conductor part 40, which has an increased material wear result, especially if the connector high mechanical loads such is exposed to vibrations.

For this reason, an elastically compressible damping element 50 is provided on the connector 10 according to the invention. When pressure is exerted in the insertion direction S on the damping element 50, this is compressed, whereby the mobility of the inner conductor contact 20 with respect to. The insulator portion 30 and / or the mobility of the insulator part with respect to the outer conductor part 40 is reduced or eliminated altogether. The finished plug state with completely eliminated axial play 21, 22 is in Fig. 2b shown while in Fig. 2a a position in the course of insertion of the mating connector 100 is shown, in which the counter-pressure surface 105 of the mating connector 100 while already applied to the damping element 50, but this is not fully compressed.

At the in Fig. 1 In the illustrated embodiment, the damping element 50 is provided on the connector 10 in such a way that it indirectly transmits the pressure emitted by the mating connector 100 during insertion to the inner conductor contact 20 and directly to the insulator part 30. Thereby, the inner conductor contact 20, the insulator part 30 and the outer conductor part 40 are pushed together in the course of the insertion process, so that the axial Games 21 and 22 are eliminated and a rigid and immovable connection between the inner conductor contact 20, the insulator part 30 and the outer conductor contact is made.

How very clear in the FIGS. 3a and 3b is shown, the damping element 50 is substantially annular on the front end of a rigid Sprayed plastic body which forms a slidably received in a guide 32 of the insulator part 30 sliding member 60. When pressure is exerted on the damping element 50 in the insertion direction S, the sliding element 60 fastened thereto is pressed into the guide 32 and displaces the inner conductor contact 20 abutting thereto in the direction of a stop 33 of the insulator part 30.

The damping element 50 forms the leading during insertion of the mating connector front surface of the connector to which by the in the FIGS. 2a and 2b shown counter-pressure surface 105 of the mating connector 100 pressure is exercisable. In this case, the front surface of the damping element 50 is not flat, but arranged convexly curved, so that in the course of the insertion process first a portion 55 of high material density comes into contact with the counter-pressure surface 105 and the sliding member 50 urges in the direction of the inner conductor contact 20. Subsequently, a portion 56 of low material density which bears directly against the insulator part 30 comes into contact with the counter-pressure surface 105 and presses the insulator part in the direction of the outer conductor part 40. Alternatively or additionally, the insulator part 30 becomes indirectly via the inner conductor part 20 in the direction of a contact surface of the outer conductor part 40 pressed.

While at the beginning of Einsteckvorgangs still axial play 21 and 22 between the inner conductor contact 20, the insulator part 30 and the outer conductor part 40 are present (see Fig. 2a ), are radially extending contact surfaces of inner conductor contact 20, insulator part 30 and outer conductor part 40 after completion of the insertion closely and without play against each other (see Fig. 2b ).

In order to facilitate the insertion process and to allow a more stable coupling, the connector 10 and the Gegenteckverbinder 100 form-locking or non-positively acting connecting means, such as screws, brackets or clamps, by means of which the mating connector, starting from the position according to Fig. 2a in the position according to Fig. 2b can be pulled. The connecting means also prevent accidental release of the connector.

Fig. 4 shows a slightly modified embodiment of a connector 10 'according to the invention, in which the sliding member 60', on the front end of which Damping element 50 is sprayed, is not held axially displaceable in a guide groove of the insulator member 30, but in a radial guide 32 ', which rests radially outward on the sliding member 60'. Again, the rear end 61 of the sliding member 60 'abuts the inner conductor contact 20, while the damping element 50 formed as a soft component can not come into direct electrical contact with a current-carrying part.

Fig. 5 shows a second embodiment of a connector 10 "according to the invention. This connector is designed as an angle plug or an angle bushing, in which the main axis H of the inner conductor contact 120 or the insulator part 130 transversely, in particular perpendicular to the insertion direction S. In this way, the inner conductor perpendicular to the insertion direction S. The inner conductor contact 120 of the second embodiment has, on the one hand, a contact element 122 with contact spring for contacting one or more contact pins 101 'of the mating connector 100' and, on the other hand, a rod-shaped extending along the main axis H starting from the contact element 122 Ladder part 121 which is connectable to the inner conductor 72 of the coaxial cable 70.

The contact element 122 of the inner conductor contact 120 is held by an insulator part 130 made of a non-conductive material. The arrangement of inner conductor contact 120 and insulator part 130 is accommodated in an outer conductor housing 140, which forms a shield.

As in Fig. 8 1, the inner conductor contact 120 is first connected to the inner conductor 72 of the coaxial cable to produce the connector 10 ", then the insulator part 130 is attached to the inner conductor contact 120. The arrangement of insulator part 130 and inner conductor contact 120 is along the main axis H perpendicular to the Plug-in direction S extends, inserted into a pipe section 141 of the outer conductor part 140 (see Fig. 8 ). At a substantially flat rear wall of the outer conductor part 140, a damping element 51 is arranged in the form of an elastically compressible soft component. As in Fig. 7 is shown, the connector may also have more than one, for example. Two or three damping elements 51. The damping element 51 is substantially disc-shaped and has a central portion with a larger dimension in the insertion direction S as the edge portions of the damping element 51. In other words, a curvature of the damping element 51 projects into a mounting space of the outer conductor part 140 for receiving the insulator part 130.

If the arrangement of inner conductor contact 120 and insulator part 130 of the in Fig. 8 shown position in the in Fig. 5 is pushed shown position, the front end of the insulator portion 130 and the front end of the inner conductor contact 120 is deflected by the projecting into the mounting space damping element 51 opposite to the insertion direction S. The damping element is then arranged between a planar contact surface 142 of the outer conductor part 140 and a counterpressure surface 131 of the insulator part on the side of the insulator part 130 facing away from the inner conductor contact 120. In this position, the front ends of the inner conductor contact 120 and insulator part 130 are movable relative to the outer conductor part 140 in the insertion direction S.

When inserting the complementary mating connector 100 'in the insertion direction S, this mobility is limited by the fact that the insulator part 130 is pressed under the mating connector 100' acting pressure against the bias of the damping element 51 attenuated in the direction of the contact surface 142 of the outer conductor part. First, the damping element 51 is only slightly compressed (see Fig. 6a ). Only in the last part of the insertion process, namely when screwing the outer conductor part 140 of the connector with the mating connector 100 ', the damping element 51 is strongly compressed, thereby reversing the deflection of the inner conductor contact 120 and the insulator portion 130 with respect to the main axis H reversed. In the in Fig. 6b shown connection position, the insulator part 130 is substantially immovable with respect to. The outer conductor part 140 is arranged. Strong vibrations are damped in this connection position by the damping element 51, whereby wear of insulator part 130 and outer conductor part 140 is reliably minimized.

The two explicitly explained embodiments of the present invention are merely exemplary. Thus, the damping element 50, 51 is not necessarily annular or disc-shaped. Also, a connector, depending on the size and number of inner conductor contacts, have more than one damping element. According to the invention it is important that the damping element is provided on the connector so that it is compressed elastically only when mating with the mating connector, and a wear-promoting mobility between the insulator part, the inner conductor contact and the outer conductor part is thus eliminated only during manufacture of the finished connector.
