Description

  The invention described in the claims of the present application includes a substrate provided with operation elements such as a plurality of light emitting elements and a plurality of connection terminal portions electrically connected thereto, and driving for the plurality of operation elements. The present invention relates to a board connecting device for bringing another circuit board provided with a plurality of contact members electrically connected to a control circuit unit that performs control into an electrically interconnected state.

  When information communication is performed using an optical signal, an optical communication cable is used to transmit the optical signal. Various connections such as connection between optical communication cables, connection between an optical communication cable and a communication device, and the like are performed on the optical communication cable in accordance with the purpose of use and usage.

  When connecting the optical communication cable, a plug connector attached to the end of the optical communication cable and a socket connector into which the plug connector is inserted are used. In other words, the plug connector that forms the end of the optical communication cable by being attached to the end of the optical communication cable is inserted into a separately provided socket connector, thereby connecting the optical communication cable.

  Under such circumstances, when an optical communication cable is used for telephone line exchange, a situation in which concentrated connection of a plurality of optical communication cables is required occurs. In such a case, a cable connection adapter having a plurality of socket connectors each of which is inserted with a plug connector forming an end portion of the optical communication cable is prepared, and a plurality of optical communication cables are provided via the adapter. Intensive connection is made.

  At that time, in order to reduce the work burden required for connecting the optical communication cable using the cable connection adapter, the cable connection adapter may be provided with a light emitter in the vicinity of each socket connector. Has been proposed in the past. In the cable connection adapter provided with such a light emitter, when the optical communication cable to be connected is specified, the light emitter arranged in the vicinity of the socket connector corresponding to the optical communication cable is turned on. The corresponding socket connector is clearly identified. As a result, the operation of inserting the plug connector constituting the end of the specified optical communication cable into the corresponding socket connector can be performed quickly and definitely.

  When the cable connection adapter is provided with a light emitter in the vicinity of each socket connector, it is desired that the occupied space of the entire cable connection adapter provided with the light emitter is made as small as possible. And as a specific configuration that meets such a demand, for example, a thin light emitting element in which an outer surface portion of an adapter body provided with a plurality of socket connectors into which a plug connector forming a cable end is provided is electrically connected to a wiring portion It is conceivable to attach a plurality of printed wiring boards to which a plurality of thin light emitting elements are attached to each of a plurality of thin light emitting elements in a state in which they are positioned close to any one of a plurality of socket connectors. And when such a structure is taken, the connection terminal electrically connected with the control circuit part which drives and controls each of a some thin light emitting element for the printed wiring board to which the some thin light emitting element was fixed It is necessary to be electrically connected to another printed wiring board provided with the.

  Conventionally, in order to electrically connect a certain printed wiring board to another printed wiring board, a pair of board connecting connectors (for example, a male connector and a female connector) are provided on both printed wiring boards, respectively. It has been proposed to interconnect connection connectors (see, for example, Patent Document 1).

  For example, one of the two printed wiring boards is a main board under the above-described conventional method in which two printed wiring boards are electrically connected using a pair of board connecting connectors. The other is a sub-board. A female connector is fixed to the main board, and a guide portion for guiding the sub board is provided. On the other hand, a male connector is fixed to the sub-board, and an engaging portion that engages with a guide portion provided on the main board is provided. Then, the sub board is moved with respect to the main board in a state in which the engaging portion provided on the main board is engaged with the guide portion provided on the main board, and the male connector fixed to the sub board is moved to the main board. Connect to the fixed female connector. Thereby, the main board and the sub board are electrically connected to each other.
