An electrical connector in a specific design of the generic term described above falling variants is described in CH-PS 221 »7oS as a thermostat that has a plug part like with the "T-plugs" that were common in the past, at the top At the end of one of the sockets that were also common there, at the lower part a cable for the device to be connected and has a setting regulator for the actual thermostat on the front. The plug or alternatively for this purpose an incandescent lamp socket, the socket and the housing with the desire are structurally firmly united, whereby no part is interchangeable, ie. If necessary, different thermostat designs for different connection designs are needed «

In DE-PS 19 59 509 an electrical connector is described which has an electrical timer device between the connector and a Contains cable to the consumer device, with control rings with scales for the switching times embedded in the front panel are. Otherwise, the focus of this device or the cited document is in the special design and arrangement of the contact arms with the associated spring elements.

A timer according to DE-GM 18 94 373 has a plug part at one end and a socket part at the opposite end in a substantially cylindrical housing. In a further housing part penetrating this housing part at a right angle, a time switch controller with an adjusting knob is accommodated. This design leads, apart from the fact that it cannot be taken from the document, how a time switch or other more complicated electrical device with switching, display and setting devices could be installed, zn a construction that is to be connected by the

030033/0024

Consumption connection cable is too stressful tilting and can hardly maintain its position in the mains socket.

With the problem of the electrical connection via a time relay and equilateral adaptation to the terminal devices as they meet and in various An- wendaagsläadera the diesbzüglicheo national "provisions therefore be forcibly aisstauselÄar Müs =" sen _f when the plug-in device only minimal demands for rational Manufacture is to meet, see also DE-GM publication 76 11 675. There is a plug-in device with a built-in timer is described, on the rear wall of the Änsehlußvorrichttmg integrally connected to the housing wall and thus arranged interchangeably with this »Also on the rear wall a cable for connecting the brewer device is led out of the inside of the housing, although it is mentioned that several connection devices can be arranged on the back or on the side; however, exact details are not described, especially since the essential principle there of replacing the rear housing part together with the built-in plug or »socket part could not then be easily implemented«

The present invention is based on the object of a plug-in device of the type relevant here Art to improve the structure and the housing so that they can be adapted to the various without significant changes in production Regulations of the countries of application can be adapted, as well as for the installation of various switching and / / or display devices with suitable or necessary operating elements is suitable. In addition, the Arrangement of the front display and / or control panels and also the stick box attachment, the latter in there Usually down without affecting the bracket jellyfish ~
