PLUG

Abstract

Provided is a plug having a first plug piece and a second plug piece. The plug pieces are designed to enter in contact with each other, a male end of plug piece being accommodated in a first female end of plug piece. When the first plug piece is in contact with the second plug piece, electric contact elements accommodated in the plug pieces are in contact with each other. An insert accommodated in the female end of the first plug piece prevents inadvertent contacts by foreign bodies in the female end.

DETAILED DESCRIPTION OF THE INVENTION

[0031] FIG. 1 shows a plug-in connector in a perspective representation. The plug-in connector consists of a first connector part 10 and a second connector part 20. In this exemplary embodiment, the connector parts 10, 20 plug-in connector modules, designed for use in a modular plug-in connector.

[0032] The first connector part 10 has, at its end that is located in the plug-in direction, a first plug-in side 10.1. The first plug-in side 10.1 is realized such that a second plug-in side 20.1 of the second connector part 20 is accommodated therein.

[0033] The first connector part 10 is shown in FIG. 2. A first contact element 11 is accommodated centrally in the first connector part 10. The first contact element 11 projects, by a plug-in end, into the first plug-in side 10.1 of the connector part 10.

[0034] The first plug-in side 10.1 of the connector part 10 is constituted by a first formed-on portion 10.2. The first formed-on portion 10.2 in this case constitutes a full-perimeter, first collar 10.3. At the same time, in this case the first formed-on portion 10.2 constitutes the housing of the connector part 10.

[0035] The first contact element 11 is visible inside the first collar 10.3. An insert 30 is provided in the intermediate region between the first collar 10.3 and the first contact element 11. The insert 30 prevents foreign bodies such as small parts, or also a finger of a person, from being able to enter the gap and cause an electrical short circuit.

[0036] The first connector part 10 From FIGS. 1 and 2 is shown again, in separated form, in FIG. 3. It can be seen here that the first formed-on portion 10.2 constitutes the first collar 10.3. The first collar 10.3 in this case surrounds a first free space 10.4 in the plug-in side 10.1 of the connector part 10. The first free space 10.4 serves to accommodate the first contact element 11 and the insert 30.

[0037] Such an insert 30 is represented in separated form in FIG. 4. The insert 30 consists substantially of a multiplicity of—here seven—third formed-on portions 30.2. The third formed-on portions 30.2 are disposed around an opening 30.1. The opening 30.1 serves subsequently to lead through the first contact element 11.

[0038] The third formed-on portions 30.2 are formed onto a base of the insert 30. The base serves at the same time for latching the insert 30 in the first free space 10.4 of the first connector part 10.

[0039] A second connector part 20 of the plug-in connector is shown in FIG. 5. The perspective representation provides a view of the plug-in side of the connector part 20 that constitutes a second plug-in side 20.1. According to the invention, the second plug-in side 20.1 consists of second formed-on portions 20.2 The latter extend in the plug-in direction.

[0040] The second formed-on portions 20.2 are disposed such that they constitute a plurality of second collars 20.3. The second collars 20.3 are disposed in the second plug-in side 20.1 such that they surround a plurality of—here five—second free spaces 20.4. The second free spaces 20.4 serve, in the case of contacting the first connector part 10 with the second connector part 20, to accommodate the third formed-on portions 30.2 of the insert 30.

[0041] The middle second free space 20.4 is designed to accommodate a second contact element 21 in the second connector part 20. In the contacted state, the contact region of the first contact element 11 is additionally accommodated in the second free space 20.4.

[0042] The interaction, according to the invention, between the first collar 10.3, the second collar 20.3 and the third formed-on portions 30.2 is represented in FIG. 6. This shows a cross section through the first plug-in side 10.1 and the second plug-in side 20.1 of two contacted connector parts 10, 20.

[0043] The contours of the first collar 10.3 that encompasses all other parts, in the outer region, can be seen. The contour of the second collar 20.3 adjoins the inside of the first collar 10.3 in a positive-locking manner. The free spaces 20.4 between the second collar 20.3 are again filled, in a positive-locking manner, with the third formed-on portions 30.2.

[0044] The contours of the formed-on portion 10.2, the second formed-on portion 20.2 and the third formed-on portion 30.2 are represented again, in separated form, in FIGS. 7, 8 and 9.
