The present invention relates to an electronic clock module, in which a clock module which incorporates all the elements for maintaining the time of the digital display and the digital display in a case made of plastic material and at the same time includes a necessary battery, is already known. . Since the battery is actually a tablet type, the module uses a disc type battery and is contained in a wrist watch case of a general structure.

A wrist watch having several modules for operating a display element, a power supply, and an electronic circuit is also known from German Patent Application No. 2,501,234.

The object of the present invention is to provide a watch module that is freely constrained by the shape of the watch and not by the battery, but by a structure having a commodity value, so that it can be suitably used as ornaments as ornaments or as a present or daily necessities. have.

The present invention has an electronic circuit consisting of a digital display, a time-keeping oscillator, an integrated circuit for the operation of the indicator, and a contactor for indicator adjustment. Is assembled in a layered structure on a plate, and the contactor is connected to a digital display on its longitudinal side and to an external power source on its narrow side or its cross-section. Is arranged so that the control terminal for the digital display is arranged on its longitudinal side or other narrow side or section.

Embodiments of the present invention are set forth by way of example in the accompanying drawings. In FIG. 1, in a clock module having a cylindrical (preferably metal) case 1, there is a digital indicator 3 displaying the hour and minute on the back of glass plate 2 therein. The display point 4 of the indicator indicates the movement of the clock by light of the rhythm of the seconds. The battery connecting terminal 5 insulated from the case is disposed on the narrow side or the end face of the case. However, in the present invention, particularly in the case of using a case of plastic material, two contact terminals 5 with respect to the battery anode may be arranged on the end face side of the case. In principle, this terminal can also be arranged on the longitudinal side of the case, for example, away from the indicator.

Making the case into a rod and a more desirable cylinder allows for a great deal of flexibility in the structural unit. That is, since one or several batteries are not installed in the module case itself, the shape of the module need not be limited according to the size of the battery. Therefore, when designing a wristwatch or a small alarm clock, the designer can place the battery where it is most suitable for the design and eliminate the need for placing the battery directly near the module. Therefore, it is possible to make a clock with a design very different from the previous one. In addition, the module can be decorated with ornaments by making the case from expensive materials or by using an appropriate artistic design. In this case, the power supply can be installed in a second module that is artistically suitable for the clock module. The watch module can also be installed in a lighter electronic calculator that contains batteries.

The structure of the electrical subassembly of the clock module shown in FIG. 1 can be seen in FIGS. 2-4. The electrically acting partial assembly is arranged on the intermediate plate 6, on which the first conductive plate 7 and the second conductive plate 8 are placed. The conductive plate 7 has an integrated circuit for evaluating the impulse of the time holding element and a driving circuit for the indicator, and includes a crystal 12 and a crystal adjusting trimmer 9 as time holding elements. Other electronic timekeeping components, such as RC-oscillators, may be used instead of crystal oscillators. The conductive plate 8 has a digital display of the LEO display type. Although not shown in the figure, the intermediate plate 6 has several pins connected to the conductive plate 7 and the conductive plate 8 to electrically connect both of them. The pins also connect the two conductive plates mechanically to the intermediate plate.

The structure of the layered electronic partial assembly described above is particularly advantageous in designing a clock module in the form of a rod. If necessary, a digital display can be used as an LCD display.

At one end of the two conductive plates 7 and 8, there is a battery connection terminal 5 described above, and at the other end, there is a control terminal for digital display adjustment, which is placed in opposite directions. In the second drawing, it can be seen that the leaf spring 11 is located on the narrow side of the electronic partial assembly, which serves as a second battery connection terminal and makes direct contact with the case 1.

The figure 4 in cross section shows the contour of the case 1 and the fixing state of the intermediate plate 6 therein.

The adjustment terminal 10 can be placed on the long side of the case if necessary.

Since the function of the electronic clock module according to the present invention is the same as that of the electronic clock module controlled by a general crystal oscillator, as shown in FIG. 5, in the structure of the clock module of the present invention, the trimmer capacitor 9 is integrated. A crystal oscillator with a circuit, in particular a divider for the crystal oscillator pulses), and a drive circuit (with the amplifier and decoding means for display 3) are mounted on the conducting plate 7.
