ようにした従来例である。FIG. 3 shows a conventional device in which an electronic device 1 such as a pager is placed in a recess 2a of a signal transmission device 2, and a conductive rod 3 extending from the bottom of the recess is attached to a connection hole 1a on the bottom of the electronic device 1. This is an example.

端部が接触して導通状態となるように構成されている。As such a connection structure between the electronic device 1 and the signal transmission device 2, the one shown in FIGS. 4 and 5, for example, is known. As shown in FIG. The tip of the conductive rod 3 is configured to come into contact with a conductive receiving plate 7 extending from the substrate 6, thereby creating a conductive state.

慮される。In this conventional example, since the metal receiving plate 7 is fixed to the periphery of the hole 1a via the packing 8, the printed circuit board 6 and the receiving plate 7 are always connected. Therefore, there is a concern that static electricity accumulated in the wearer's body may enter the receiving plate 7 through the fingers or the like, causing damage to the self-memory elements on the printed circuit board.

However, in order to increase the conductivity by applying pressure to the conductive rubber above a certain level using a conductive rod, it is necessary to press the opposite side of the conductive rubber with a receiving plate so that it cannot be elastically deformed. Become. Although the conductive rubber is constructed so that it cannot be elastically deformed, there are other ways to ensure electrical continuity between the conductive rubber and the receiving plate extending from the printed circuit board other than keeping them in constant contact. 64 If the receiving plate is kept in constant contact with the conductive rubber, even if the conductive rubber exhibits high resistance in a non-pressure state, static electricity from the wearer's body will directly invade the printed circuit board and cause memory damage. There remains a risk that the elements etc. will be destroyed.
