The invention relates to a contact connection, in particular for motor vehicle devices, in which a strip-shaped flat plug that consists of a plug part and a fastening part bent approximately at right angles thereto, with a device connection part is conductively connected, with flat plug and device connector isolated on the two different Sides of a load-bearing housing wall are attached.

There is a connector for a switch in motor vehicles known, which is in a base plate is attached from insulating material. The connector is designed with shoulders with which it is on the one hand Side presses against the insulating plate. On the other side of the metal strip are two side tabs peeled off, which lie firmly against the insulating plate. This connector plug connection is simple, however to be used only in fastening parts made of insulating material.

The invention is based on the object of a contact connection for. To create metal housing, in which an externally arranged connector with a device connector in the interior of the housing is conductively connected. When solving the problem, make sure that the contact connection is as simple and cheap to manufacture as possible.

According to the invention, this object is achieved with a contact connection of the type described at the beginning solved in that at least one tongue is punched out of the fastening part of the blade terminal and approximately at right angles to the outside parallel to the direction of the plug part is bent, the tongue leading through the supporting housing wall and serves as a fastening rivet for the device connector.

At. Use of the contact connection for connecting and securing an outside one Device housing lying flat plug with a device connection part arranged isolated in the housing it is proposed in an embodiment of the invention that the punched and bent at right angles First tongue is an insulating washer on the outside of the housing, which is covered with a square Approach engages in a square housing opening, as well as one lying on the inside of the housing Insulating washer and the device connecting part lying on this insulating washer, e.g. Legs Luminous contact spring, penetrated.

It is also proposed that the provided for the tongue in the round insulating washers Breakthroughs lie outside the center of the pane, so that the frame-shaped fastening part of the flat

Steckers with all frame legs on the round

^J 5 insulating washer is in contact.

An exemplary embodiment of the invention is shown in the drawing. With the aid of this exemplary embodiment, the invention will be repeated below explained in more detail.

The drawing shows a section through the contact connection and the individual components pulled apart in a perspective view.

A flat plug 1 formed from a sheet metal strip consists essentially of a protruding plug part 2 and a fitting fastening part 3 bent at right angles. A tongue 4 is punched out of the fastening part 3 and bent at right angles so that the root of the tongue 4 is close to the plug part 2 . The tongue 4 first penetrates a round insulating disk 5, which has a rectangular extension 6. This rectangular approach 6 engages in a rectangular opening 7 in the housing wall 8. On the inside of the housing wall 8, the tongue 4 penetrates an insulating disk 9 and a device connecting part 10, which is used as a lamp contact spring, and rivets the end of the tongue 4 below the contact connection is formed by pressing the individual parts together at the same time. So that the frame-shaped fastening part 3 of the blade terminal 1 rests with all legs on the underside of the insulating washer 5, the openings intended for the tongue 4 in the insulating washers 5 and 9 are arranged outside the center.
