technical field

The utility model relates to a sensor module for a plug-in connector and a system composed of the plug-in connector and the sensor module for the plug-in connector.

detailed description

The sensor module 1 shown in FIG. 1 has a substantially square design. A metal structure 3 is applied to the end face 2 of the sensor module 1 , which metal structure forms an electrical component 4 . Electrical component 4 is here a plurality of capacitors connected in parallel.

The sensor module 1 is made of a metallizable plastic which can be provided with the aforementioned metal structures by means of MID technology. A suitable MID process is described, for example, in EP 1 898 682 B1. It can also be advantageous if the sensor module is only partially made of metallizable plastic and the remainder is made of normal plastic. Only the part forming the end face 2 has to be metallizable. Material costs can thus be saved.

The sensor module has so-called holding tabs 5 on both sides, by means of which the sensor module 1 can be fixed in an articulated frame (not shown). The sensor module 1 has two openings 6 into which contact elements (not shown) can be inserted. The sensor module 1 can thus assume the tasks of hitherto known modules and at the same time fulfill sensor functions. As a result, the design of the sensor module shown here can be used in a particularly space-saving manner.

The side surfaces of the sensor module 1 are provided with two connection surfaces 7 , which are provided with the electrical structure 3 electrically conductively connected to the electrical components 4 . The electrical component 4 can be electrically contacted via the connection surface 7 and integrated into a sensor circuit (not shown) and/or connected to an evaluation electronics (not shown).

The core of the utility model is briefly summarized again below: the utility model relates to a sensor module 1 for a plug-in connector, wherein the sensor module 1 is basically constructed in a square shape, wherein the end side 2 of the sensor module 1 is provided with a metal structure 3, The metal structure forms an electrical component 4 , wherein the electrical component 4 forms at least one capacitor.
