Anti-theft device for an automobile audio set
First Claim
1. An anti-theft device for an audio set slidably insertable into an installation recess of a motor vehicle and which has an actuatable module means controlled by a change-over switch means which is actuated to prevent operation of the audio set when the audio set is pulled out of the installation recess, comprising:
- a change-over switch means which, in at least one switching position, is electrically connected through a first plug connection element means at the rear wall of the audio set with a theft module means of the audio set, which change-over switch means is moved to a second position upon an unauthorized pulling out of the audio set to cause actuation of the theft module means as a result of a change of electrical potential, as a result of which the audio set is rendered inoperative;
the audio set, at its rear wall, having at least a second plug connection element means connectable to a power supply from the wiring system of the motor vehicle;
a housing contains the change-over switch means, as well as plug connection element means which match the plug connection element means at the rear wall of the audio set and which are connectable therewith;

Abstract
An anti-theft device for a car radio having a theft module, which renders the car radio inoperative when the radio is slid out of its installation recess in the vehicle, is provided by a joint housing for a power supply and anti-theft protection plug connection elements, as well as for a change-over switch controlling the theft module. The housing is fastened via the plug connection elements at the rear wall of the car radio such that the change-over switch is inevitably actuated by the frame of the installation recess during the sliding-out of the radio.
