Electrical plug connector
First Claim
1. An electrical plug connector for connection of an electrical cable to an apparatus, including a sensor or an actuator, or for detachable connection of two electrical cables to one another, the electrical plug comprising:
- a housing, having a contact mount that holds a plurality of contacts, and including an electronics circuit arranged in the housing and with the electronics circuit having at least one light-emitting element, including an LED and being electrically connected to the contacts,wherein the housing is composed of a thermoplastic material, at least in an area of the light-emitting element, the thermoplastic material having an additive that influences transparency and color, and that reduces the transparency of the thermoplastic material, andwherein the additive is a color concentrate with at least one of an organic and an inorganic colorant, and having a dark color, so that when the LED is illuminated, the LED is seen from outside the housing, and when the LED is not illuminated, the LED and the electronics circuit are not seen or are seen only poorly, and a clear increase in contrast is achieved, and so that a status of the LED is easily seen when the plug connector is subject to strong external incident light.

Abstract
An electrical plug connector for connection of an electrical cable (2) to an apparatus, such as a sensor or an actuator, includes a housing (3) having a contact mount (5) holding a variety of contacts (4), and an electronics circuit (6) having at least one light-emitting element, LED (7) and being electrically connected to the contacts (4). The status of whether the LED (7) is illuminated or not can be identified particularly well, even in the presence of strong external incident light, by the housing (3) being composed of a thermoplastic material, at least in the area of the LEDs (7), and including an additive (8) that influences transparency and color for reducing the transparency of the thermoplastic material.
