Electrical plug for car sockets and / or car cigar lighter

The innovation relates to an electrical plug, in particular for car sockets and / or car cigar lighter according to the features of the preamble of the protection claim 1.

Such electrical car plugs usually consist of two composable Housing halves made of insulating material into which a pin-shaped Center contact and an external contact piece are stored. Around such a plug into a car socket with a small diameter or a car cigar lighter with a larger one, as required Use diameter su can, it is known that the plug-in part of the plug for use in a car socket accordingly to train small. For use in a car cigar lighter, a plug is then simply inserted via the plug-in part of the plug appropriate adapter pushed, which corresponds to the diameter of the cigar lighter is equivalent to.

With such compatible plugs with adaption part for different Socket diameter, unintentional short circuits can easily occur. The protection of the car sockets and cigar lighters are often protected together with other consumers in the car, so that in the event of a short circuit, they will also fail. A fuse exchange may be necessary immediately, depending on the accompanying circumstances - failure of the headlights, Taillights etc. - can be more than unpleasant for the driver in bad weather and traffic conditions.

The object of the innovation is therefore to create a plug for different car socket diameters that does not cause any such consequences.

This task is carried out in the characterizing part of the claim 1 specified measure solved. Further refinements of the innovation can be found in the subclaims.

An embodiment of the innovation is shown in the drawing and is described in more detail below. Show it:

- Fig. 1 - a plan view of the inside of the housing half of an electrical car plug,

- FIG. 2 - a section along the line A-B according to FIG. 1.

According to the embodiment according to Figures 1 and 2, the car connector consists essentially of two composite housing halves 1, in which a plug pin 2, an electrical center contact 3 and an external contact piece 4 are mounted. According to the innovation an electrical fuse 5 is arranged between the plug pin 2 and the electrical center contact 3. The backup has cone tips at the ends, with which they fit into corresponding notches 6 on the connector pin 2 and the resilient center contact 3 is held under clamping action ^ The external contact piece 4 is made in one piece and shaped so that an electrically conductive contact is provided for the respective socket diameter is. In order to better guide the plug in cigar lighters with different inside diameters, am Connector housing resilient tongues 7 formed on the opposite of the outer contact piece 4 are arranged offset by 90 °.
