Description

Steek part of a coupling plug for_Nähungsscha] .te E_oder_dgJL.i

The innovation relates to a Steckerteii a coupling connector for proximity switches or the like. In which the Plug contacts are enclosed in a plastic housing block and in which the outgoing cable of a Plastic support sleeve is enclosed.

The innovation is based on the task of having at least one of its two corresponding ones in the case of a coupling plug To train connector parts so that the connector can be seen from the outside ^ whether at their electrical Voltage is applied to the contact parts.

Kierzu -is provided according to the innovation that between the Housing block and the support sleeve inserted a ring piece is, which consists of color-transparent material and that has a cavity which is open towards the housing block and in which a light-emitting diode is arranged. The transparency of the Kingstückes lets the inserted light-emitting diode all around ha-urr. become visible, the electrical connection parts of the According to the innovation, are embedded in the housing block.

According to a preferred embodiment of the invention is provide the ring piece with channels running past the side of the cavity for the passage of the individual wires of the cable, these channels advantageously being equidistant are distributed over the circumference of the ring piece, so that the light-emitting diode in spite of the electrical running past it Lines all around remains almost evenly visible. According to further features of the innovation it can be provided that the ring piece at each end with at least |

having a circumferential groove provided end portion and that

1 each has an end section in the sprayed-on housing block and the other end section in the molded support sleeve is firmly embedded.

The subject of the innovation is explained in more detail below with reference to the drawing, which shows:

Fig. 2 is an end view of the coupling socket and Fig. 3 dis K'jppl'jngsdcse in an exial longitudinal section.

In the plug part shown, the plug contacts are here especially the sockets 1 and the socket inserts 2, injected in a plastic housing block 3, which is of a union nut 4 is enclosed, which on a assigned threaded connector of the corresponding Plug part of the coupling plug in a known manner is unscrewed. In the housing block 3 are also the j Einzelader.n 5..ein outgoing cable 6 injected. Furthermore, in the housing block 3, the connecting parts 7, a Printed circuit board 8 and a resistor 9 embedded, via the • frine light-emitting diode 10 is supplied, which is at the rear end of the housing block 3 is arranged.

The outgoing cable 6 is from a plastic support socket 11 enclosed, which is provided with a plurality of circumferential ribs 12 is and also encloses the line area on which the individual lines 13 emerge from the dumbbell of the cable 6.

A ring piece 14 is inserted between the housing block 3 and the support sleeve 11, which is made of color-transparent material and has a cavity 15 which is open towards the housing block 3 and into which the light-emitting diode 10 is inserted. The ring piece 14 is also provided with channels 16 running laterally on the hchlrsiim 15 - through which the individual wires 5 of the cable are passed. The channels 16, like the socket inserts 2 (cf. FIG. 2), are equidistant Distributed over the circumference of the ring piece 14, so that between adjacent individual wires 5 there always remain wide, transparent material areas through which the light-emitting diode 10 can be observed.

The ring piece 14 has an end section provided with a circumferential groove 17, 18 at each end. The one in Fig. 3 lower end section having the groove 18 is firmly embedded in the sprayed-on housing block 3, while the upper, the end section having the groove 17 in the injection-molded support sleeve "; 11 is firmly embedded.
