Description

[Detailed Description of the Invention] The present invention relates to a timepiece structure that ensures electrical connection when a module body and other functional units are added to an electronic timepiece.

Conventionally, insulated lead wires were used to connect the module body and the unit part, but since the unit was attached separately from the main body, the reliability of the joint part decreased as well as the number of man-hours increased. there were.

As a countermeasure to this problem, a part of an insulating sheet with a conductive pattern on which electronic components are fixed is protruded to serve as a connection lead, but even in this structure, the connection lead is routed from the top of the module to another part while it is being assembled. It has the disadvantage that it may come into contact with the case and cause a short circuit.

In order to improve the various drawbacks mentioned above, this invention protects the outside of the connection lead with an insulating inner frame that connects the module and case, preventing direct contact with the case and improving reliability. .

To explain the present invention with reference to the drawings, as shown in FIG. 1, an insulating sheet 5 having a conductive pattern on which electronic components 6 are arranged is provided on a substrate 4 positioned on a module 1 to form a unit. The portion protrudes as a connection lead 7.

Reference numeral 8 denotes a part of a connecting component or an electronic component provided to the connection lead for the module.

An insulating inner frame 3 that integrates the shell 2 and the module is provided with a groove 3a on its inner periphery at a portion through which the connection lead 7 passes, as shown in FIG.

In the above configuration, to assemble the module, first combine the module 1 and the insulating inner frame 3, then pass the connecting lead 7 of the unit through the groove 3a of the insulating inner frame 3, and then attach the module to the body 2. Incorporate 1.

At this time, the connection lead 7 has a large radius to prevent breakage due to bending.

For this reason, a bulge is created at the corner of the connection lead 7,
This contacts the shell 2 and tries to cause a short circuit, but is regulated by the insulating middle frame 3 and the contact with the shell 2 is cut off.

Figure 3 shows an electronic component 6 attached to the tip or middle part of the connection lead 7.
This is an insulating inner frame 3 that can be used when a part of the module 1 or a connecting part 8 is provided. 3b and grooves having different depths are provided in multiple stages.

As a result, a relatively large portion fixed to the connection lead portion is passed through the deep groove, and the expansion of the connection lead is then controlled by the shallow groove to prevent short circuits.

As described above, in the present invention, when adding another functional unit, the radial bulge of the connection lead that is connected to the module is restricted by the groove provided in the insulating inner frame, so that the radial bulge is restricted during or after installation. No short circuits occur.

In addition, the insulating inner frame has a multi-stage section that restricts the connection lead and a section that allows parts fixed to the connection lead to pass through, allowing for easy assembly and highly reliable electrical connection. It is.
