Description

Plug-in connector

Technical Field

The utility model relates to a according to a plug connector for with the pairing plug connector plug connection who corresponds.

Background

Such a plug connector comprises a housing and a contact insert which is accommodated in the housing and which forms a plug surface for a plug connection to a mating plug connector and has at least one electrical contact element for making electrical contact with at least one mating contact element of the mating plug connector.

In order to provide a heavy-duty plug connector which is particularly highly loaded and which is to be designed to be correspondingly stable and durable, use is made of a housing made of plastic or aluminum, which housing accommodates a contact insert which provides a configuration of the electrical contact elements in the form of socket contacts or pin contacts in order in this way to form a plug surface for plug connection with a corresponding mating plug connector. The housing and the contact inserts are configured in a modular manner and engage with one another in order to provide a plug connector, wherein different contact inserts having different configurations of the electrical contacts and correspondingly differently shaped housings having different structural sizes and mechanical designs are also used (for example for providing a locking with a mating plug connector) depending on the application of the compliance of the plug connector.

This results in significant variations across different housings. In conventional plug connectors, this change is further increased by the fact that the electrical cables are routed from the plug connector in different spatial directions depending on the application of the plug connector, which must be achieved by the housing and the cable outlet provided on the housing accordingly.

In a housing of the type known from DE 102014102930 a1, the housing is formed by a first housing part and a second housing part, which can be fitted to each other in different positions. The second housing part provides a cable outlet, wherein the cable outlet direction can be defined by the position of the second housing part relative to the first housing part.

DE 102007058159 a1 discloses a device for guiding and holding a cable harness, for example, of cables or hoses, for example, on a wall of a switchgear cabinet.

SUMMERY OF THE UTILITY MODEL

The object of the invention is to provide a plug connector with which the required changes in the housing provided for forming the modular plug connector can be reduced.

This object is achieved by a subject having the features of the present invention.

The plug-in connector accordingly has a flexibly deformable cable outlet element made of a soft material for guiding the cable, wherein the cable outlet element has a foot section to be fixed on the outlet wall of the housing and a plurality of step sections connected to one another in the cable outlet direction, the diameter of which step sections varies.

By means of such a cable outlet element, a cable outlet is provided on the housing. A cable exit element is connected to the housing and leads the cable out of the housing and away from the housing, wherein the cable exit element is flexibly deformable so that the cable can be routed away from the housing in a variable manner.

The housing may have an approximately square basic shape. In particular, the housing can be formed by side walls arranged opposite one another, which are connected to one another by end side walls. In this way, the housing can enclose a receiving space for receiving the contact insert, wherein the housing is open, for example, on the side of the contact insert forming the plug-in surface.

The outlet wall can be arranged on the side of the housing facing away from the plug surface. Preferably, the outlet wall extends at an angle to the plugging direction in such a way that the outlet wall has an angle of between 30 ° and 60 °, for example between 40 ° and 50 °, for example 45 °, relative to the plugging direction. Since the outlet wall extends obliquely to the plugging direction, a single cable outlet element can be used to provide different laying directions. The cable can thus be guided out of the plug connector parallel to the plugging direction by means of the flexibly deformable cable outlet element, in that the cable outlet element is correspondingly shaped with the cable received thereon. Likewise, the cable can be pulled off from the plug connector transversely to the plugging direction by deforming the cable pull-out element in the other direction. By arranging the outlet wall at an inclination, for example at an angle of 45 ° with respect to the plugging direction, cables can be laid along the plugging direction as well as transversely to the plugging direction without excessive deformation of the cable outlet element.

The cable outlet element is molded, for example, from a rubber material or from an elastomeric plastic. The soft material of the cable outlet element thus enables a flexible deformation of the cable outlet element, in particular for laying the cable out of the plug connector.

The flexible design of the cable outlet element furthermore enables a flexible adaptation of the cable outlet element, for example to cables of different cable diameters. Since the cable outlet element is formed from a soft material and can therefore be cut with a suitable tool, for example a blade, the user can adapt the cable outlet element for the intended use in such a way that it can receive the cable to be guided therein in a suitable manner.

For this purpose, the user can separate the cable outlet element, in particular at a stepped section, wherein the user cuts the cable outlet element at a stepped section whose diameter is suitable for accommodating the cable to be guided. Since the cable outlet elements have a plurality of interconnected stepped sections with different diameters, the cable outlet elements can be variably adapted to the cables to be guided.

The stepped sections may each have a cylindrical shape with a circumferential cylindrical side surface. Thus, each step section has a constant diameter within the respective step section. However, the diameters of adjacent stepped sections are different from each other.

In particular, the diameter of the stepped section can decrease from the foot section. The diameter of the stepped section is therefore reduced starting from the foot section, so that an approximately conical, but stepped shape of the cable outlet element is obtained. Thus, the step section furthest from the foot section has the smallest diameter. Towards the foot section, the diameter of the stepped section becomes larger. Thus, by separating the cable lead-out element at a suitable step section, the cable lead-out element can be adapted to receive wires having a specific cable diameter at the cable lead-out element.

Due to the step sections connected to each other with different diameters, a stepped shape of the cable outlet element is obtained. In this case, a base section can be formed between two adjacent step sections, which base section extends along a plane extending transversely to the cable exit direction and projects radially outward on the adjoining step section, for example with a circumferential web.

In one embodiment, the foot section of the cable outlet element is inserted into an opening of an outlet wall of the housing in order to fix the cable outlet element on the outlet wall. The cable outlet element can be fixed to the outlet wall by means of the foot section, for example, in a form-fitting or material-fitting manner, wherein the foot section can be fixed to the outlet wall of the housing during the manufacture of the housing and therefore before the delivery of the housing, or the housing and the cable outlet element can be delivered separately from one another, in order to mount the cable outlet element on the housing only when the plug connector is assembled (i.e. when the contact insert connected to the cable is engaged with the housing by a user).

The material-to-material connection can be established, for example, by adhesive bonding. However, it is also conceivable, for example, to manufacture the cable outlet element integrally and integrally with the housing when the housing is manufactured from plastic, for example using a two-component injection molding method.

If the cable outlet element is connected to the outlet wall of the housing in a form-fitting manner, the foot section of the cable outlet element can, for example, have a first engagement means which engages with a second engagement means of the outlet wall in order to fix the foot section on the outlet wall. One of the engagement means can be formed, for example, by an engagement tab, while the other engagement means is formed by a complementary engagement groove. In the interconnected position, the engagement means engage with each other in a form-fitting manner and in this way establish a form-fitting connection between the cable outlet element and the housing.

If the foot section of the cable outlet element is inserted into the opening of the outlet wall, the first engagement means of the foot section can be formed, for example, as a groove which runs circumferentially around the foot section, while the second engagement means of the outlet wall are formed as a web which circumferentially surrounds the opening.

In one embodiment, the foot section can be releasably fixed to the outlet wall. In particular, in the case of a form-fitting connection of the cable outlet element to the housing, the connection between the cable outlet element and the housing can be released again, for example, in order to arrange the cable outlet element on the cable when the plug connector is assembled and to cut the cable outlet element on a stepped section in order to adapt the cable outlet element to the cable diameter of the cable. However, the cable outlet element can also be released in particular when the plug connector is plugged with a mating plug connector, in order in this way, for example, to gain access to the receiving space of the housing, for example, in order to subject the components in the receiving space of the housing to a visual inspection or, if appropriate measuring equipment is used, to an electrical inspection.

For example, with the cable outlet element being realized completely or partially from a transparent material, it is possible to allow a view of the interior of the housing of the plug connector or to make a display of the interior of the housing visible. For example, the functional elements or electrical interfaces in the interior of the housing can be checked by cable outlet elements which are completely or partially made of transparent material, or an internal display, for example in the form of a display or a diode, can be made visible from the outside in order to display optical signals, for example color signals.

In one embodiment, the cable outlet element has an inner cavity through which the cable is guided. The inner cavity may for example be defined by an inner wall, which preferably has a conical shape. The interior is thereby constricted in the cable outlet direction away from the foot section and is therefore narrower at its end remote from the foot section than at its end facing the foot section. For cables connected to the plug connector, the cable extends in an interior, wherein the cable outlet element preferably bears sealingly against the cable in order to prevent moisture and dirt from entering the housing interior.

In one embodiment, the cable outlet element can be fastened to the cable guided on the cable outlet element by means of a fastening device, for example in the form of a cable tie, wherein such a fastening device is placed around the cable outlet element and tensioned.

Detailed Description

Fig. 1 to 6 show an embodiment of a plug connector 1 which can be plug-connected to a corresponding mating plug connector 2 in a plugging direction E (see fig. 2 and 6) in order to establish an electrical connection between the plug connector 1 and the mating plug connector 2.

The plug connector 1 has a housing 10 which is formed by side walls 101 which face one another, an end side wall 102 which connects the side walls 101 to one another, and an upper wall 103 and encloses an accommodation space in which the contact insert 13 can be accommodated (see the sectional view according to fig. 6). The contact insert 13 has the form of electrical contact elements 130 which form the plug surface 11 of the plug connector 1 on the open side of the housing 10 facing away from the upper wall 103 and which engage when the plug connector 1 is plugged into connection with corresponding mating contact elements 200 of the plug surface 20 of the mating plug connector 2 and in this way establish an electrical connection between the plug connector 1 and the mating plug connector 2.

An electrical cable 14 is arranged on the plug connector 1, said cable having a conductor core 140 guided therein. The conductor cores 140 are connected to the contact elements 130 of the contact inserts 13, so that the cable 14 is connected to the mating plug connector 2 via the plug connector 1 and can thus be connected to corresponding electrical components, for example, in a switchgear cabinet.

In order to guide the cable 14 out of the housing 10, a cable outlet element 12 is provided, which in the exemplary embodiment shown has a conical basic shape and is made of a soft material, in particular a rubber material or an elastomeric plastic material.

The cable outlet element 12 forms a cavity 127 which is delimited by the conical inner wall 123 and is intended to receive the cable 14. The cable 14 extends through the lumen 124 such that the cable 14 exits the housing 10 in a cable exit direction K.

The cable outlet element 12 has a foot section 124, via which the cable outlet element 12 is arranged in an opening 105 on the outlet wall 104 in the region of the upper wall 103 of the housing 10. A plurality of stepped sections 120, each having a cylindrical shape and being connected to one another along the cable exit direction K, are arranged on the foot section 124, so that the cable exit element 12 tapers in a stepped manner from the foot section 124 in the cable exit direction K.

In particular, the step sections 120 have different diameters D1, D2 (see fig. 2), wherein the diameter D1 of the step section 120 closer to the foot section 124 is respectively greater than the diameter D2 of the step section 120 adjacent thereto in the cable exit direction K.

Between the two stepped sections 120, a bottom section 126 is formed, which extends circumferentially along a plane extending transversely to the cable exit direction K, as can be seen for example from fig. 1 and in connection with fig. 6. Radially projecting on each base section 126 is a web 121 which projects radially with respect to the stepped section 120 adjoining opposite the cable exit direction K, as can be seen, for example, from fig. 6.

At the end remote from the foot portion 124, the cable outlet element 12 is delimited in the initial state by an end face 122, by which a conical interior 127 is delimited in the cable outlet direction K. In order to adapt the cable outlet element 12 to the arrangement of the cable 14 on the plug connector 1, the cable outlet element 12 can be cut at the stepped section 120 (along a section S extending transversely to the cable outlet direction K, as is shown by way of example in fig. 6) in such a way that the interior 127 is opened and the cable 14 to be guided can be led out of the cable outlet element 12. The axial position of the cross section S is to be selected such that at the outlet of the cable outlet element 12 a clear width of the interior 127 is obtained, which is adapted to the cable diameter of the cable 14, so that the cable outlet element 12 can rest on the cable 14 in a sealing manner (with slight elastic elongation) in the circumferential direction at its outlet.

To complete the plug connector 1, the cable 14 to be used is connected to the contact insert 13, the contact insert 13 is engaged with the housing 10, and the cable 14 passes through the cable outlet element 12. By using suitable fixing means, for example in the form of cable ties, the cable 14 can be fixed to the cable lead-out element 12 by placing and tensioning the fixing means around the cable lead-out element 12.

In the exemplary embodiment shown, the foot portion 124 is connected in a form-fitting manner to the outlet wall 104 of the housing 10. For this purpose, an engagement groove 125, which runs around the cable outlet direction K and which, in the connected position, engages in a form-fitting manner with an engagement tab 106 running around the opening 105 of the outlet wall 104, as can be seen from fig. 6, is formed on the foot portion 124. The cable outlet element 12 is thus fixed to the housing 10 by the foot section 124 and its positive engagement with the housing 10.

Additionally or alternatively, a material-fit connection can be produced between the cable outlet element 12 and the housing 10, for example by means of adhesive bonding.

If the cable outlet element 12 is connected to the housing 10 by its foot section 124 in a form-fitting manner, the connection between the cable outlet element 12 and the housing 10 is preferably releasable. This makes it possible in particular to deliver the housing 10 with the cable outlet element 12 arranged thereon, wherein the cable outlet element 12 can be released from the housing 10 by a user in order to adapt the cable element 12 to the cable 14 to be guided and arranged on the cable 14. Furthermore, such a releasable connection enables the elements in the housing 10 to be checked visually or with regard to measurement techniques when the plug connector 1 is connected to the mating plug connector 2 in a plug-in manner that the cable outlet element 12 is released and thus the opening 105 in the outlet wall 104 is partially released and thus the interior of the housing 10 can be accessed.

Since the cable lead-out element 12 is made of a flexible soft material, the cable 14 can be routed out of the housing 10 in a flexible manner. In particular, by deforming the cable outlet element 12, the cable 14 can be led away from the housing 10 in a direction transverse to the plugging direction E or also counter to the plugging direction E.

The cable outlet element 122 can be made of a transparent material, for example, in order to be able to see into the housing 10.

In the embodiment shown, the outlet wall 104 has an angle α (e.g. 45 °) to the plugging direction E and is thus arranged obliquely to the plugging direction E. This enables the cable 14 to be laid out of the housing 10 in a direction transverse to the plugging direction E or also in a direction opposite to the plugging direction E with the cable outlet element 12 deformed, without the cable outlet element 12 having to be excessively deformed here. Since the outlet wall 104 is arranged obliquely to the plugging direction E, the cable 14 needs to be bent by an angle of, for example, only 45 ° for the purpose of laying from the housing 10, and accordingly the cable outlet element 12 does not have to be excessively deformed.

The idea on which the invention is based is not limited to the embodiments described above, but can also be implemented in a completely different way.

Plug connectors of the type described here can be used in completely different ways. A plug connector of the type described here makes it possible in particular to implement a so-called heavy-duty plug connector which is to withstand high loads and is accordingly designed to be durable.

The cable outlet element is not limited to the form shown, but can also be embodied in a completely different manner.
