DE2054757B2 - ELECTRIC CLOCK WITH PLUG-IN CONTACTS FOR THE POWER SUPPLY - Google Patents

Description

45

The invention relates to an electric clock, which is located outside of the movement capsule Voltage source is fed, preferably car clock, with arranged on the movement capsule Plug contacts for the power supply.

In the case of the known electric car clocks, there are flat or round plugs on the back of the movement capsule provided, which can be connected to the terminals of the battery via corresponding sockets. In most designs, the connector connected to the battery's negative terminal is on the Factory capsule welded on, while the plug connected to the positive pole of the battery is connected to an am Clockwork attached insulating material is arranged and provided with an insulating plug opening of the watch case protrudes.

There are also known car clocks in which the movement capsule is not used as a ground connection. In In this case, both connectors are arranged on an insulating plate attached to the clockwork and protrude from the capsule by means of corresponding insulation. Here is the work capsule even with additional funds on the clockwork, e.g. B. on the motherboard attached.

The known designs require the lead out of the plug contacts for their attachment and for the additional fastening of the insulating material plate that accommodates the electric drive circuit as well as the work capsule a considerable effort.

The invention is based on the object of creating an electrical clock of the type mentioned above, in which the power supply to the electric drive circuit is particularly simple Way with little effort. This is achieved according to the invention in that the plug contacts with clockwork pillars are in electrically conductive connection, which in turn with the electrical Drive circuitry for the clock are electrically connected with at least one of the clockwork pillars against the movement is arranged electrically isolated.

The power supply pillars connected to the plug contacts can preferably be used as fastening elements for one containing the drive circuit Trajteil, for di; Work capsule and be designed for the plug contacts. The supporting part for the electrical drive circuit can be provided with conductor tracks, also electrical or electronic Be component receiving insulating plate. The plug contacts are useful provided with projections or depressions that correspond to the depressions or projections of the Movement capsule or a part connected to it are in engagement, with at least one of these depressions or one of these projections is isolated from the Werkkapstl.

Due to the formation according to the invention, a very simple attachment of various parts can be achieved Achieve, this attachment is also used as a power supply. There are different Operations that were previously required for attaching the plug contacts are superfluous.

The training according to the invention makes it possible to attach the work capsule and at the same time to use the fastening elements for the capsule as a power supply for the electric drive circuit, these fastening elements also hold the power supply connector. The inventive Clock can therefore be produced with particularly little effort.

The invention is explained in more detail with reference to the drawing. In the drawing shows
