Japanese Patent Laid-Open No. 9-312183 (pages 4-5, FIGS. 1-4, 9-11) JP 2007-258001 A (pages 4-6, FIGS. 1-4)

  Wiring plate-like member to make the member side wiring terminal portion provided on the wiring plate-like member such as the flexible printed wiring board as described above connected to the board-side wiring terminal portion provided on the main wiring board. In the case where the board connecting mechanism described in Patent Document 1 that is conventionally proposed for electrically connecting to the main wiring board by face-to-face close overlapping connection is used, the plate-like member side connector is attached. When the printed wiring board-like member is electrically connected to the main wiring board on which the board-side connector is erected by face-to-face close overlapping connection, the board-side connector and the board are placed on the main wiring board. The shape member side connector is overlapped. For this reason, the distance between the main wiring board and the wiring plate-like member is made relatively large, which hinders the overall thinning including the main wiring board, the wiring plate-like member, and the board connecting mechanism between them. Will be done.

  Furthermore, when the board connection mechanism described in Patent Document 1 is used, the main wiring in which the board-side connector is erected by the face-to-face proximity overlapping connection of the wiring board-like member to which the plate-like member side connector is attached. In the process of electrically connecting the board member to the main wiring board and electrically connecting to the board, the board member side connector and the board side connector are connected in the process of fitting and connecting the plate member side connector to the board side connector. All of them are covered with the wiring plate member and cannot be viewed from behind the wiring plate member. Therefore, workability in fitting and connecting the plate-like member side connector to the board-side connector is extremely poor, and the wiring board-like member to which the plate-like member-side connector is attached is connected to the main wiring board on which the board-side connector is erected. It becomes difficult to reliably perform the face-to-face close overlapping connection, and to confirm that the face-to-face close overlap connection to the main wiring board of the wiring plate member has been reliably performed.

  In addition, since the board connecting mechanism described in Patent Document 1 is not provided with means for maintaining the state in which the plate-like member side connector is fitted and connected to the board-side connector, the board-like member side There is also an inconvenience that it is difficult to stably maintain the state in which the wiring plate-like member to which the connector is attached is electrically connected to the main wiring board on which the board-side connector is erected by face-to-face close overlapping connection. .

  Similarly, the wiring plate-like member is opposed so that the member-side wiring terminal portion provided on the wiring plate-like member such as a flexible printed wiring board is connected to the board-side wiring terminal portion provided on the main wiring substrate.

When being connected to the board, the board-side connector and the plate-like member-side connector are not stacked on the main wiring board. As a result, it is possible to avoid a situation in which the overall thinning including the main wiring board, the wiring plate-like member, and the board connecting mechanism therebetween is hindered.

  However, even in the case where the board connecting mechanism described in Patent Document 2 is used, the wiring board-like member to which the plate-like member side connector is attached is connected to the main board to which the board-side connector is attached by face-to-face proximity overlapping connection. When electrically connecting to the wiring board, the wiring plate-like member is brought close to the main wiring board so that the hole provided in the connector on the plate-like member is fitted to the outer periphery of the board-side connector. Both the sheet-like member side connector and the board-side connector are covered with the wiring plate-like member and cannot be viewed from behind the wiring plate-like member. Therefore, workability when fitting the hole provided in the plate-like member side connector to the outer periphery of the board-side connector is extremely poor, and the board-side connector of the wiring plate-like member to which the plate-like member side connector is attached is attached. It is difficult to reliably perform face-to-face close overlapping connection to the main wiring board, and to confirm that the face-to-face close overlapping connection to the main wiring board of the wiring plate member has been reliably performed. The inconvenience is the same as in the case where the board connecting mechanism described in Patent Document 1 is used.

  Furthermore, since the board connecting mechanism described in Patent Document 2 is not provided with means for maintaining the state in which the hole provided in the plate-like member side connector is fitted to the outer periphery of the board side connector, It is said that it is difficult to stably maintain a state in which the wiring plate-like member to which the plate-like member side connector is attached is electrically connected to the main wiring board to which the board-side connector is attached by face-to-face close overlapping connection. The inconvenience is the same as in the case where the substrate connecting mechanism described in Patent Document 1 is used.

Insulation how The fitting hole formed by the engaging portion 17 provided in the wiring plate-like member 14 is fitted to the outer periphery of the insulating housing 15 provided in the board-side connector 13 while directly observing both with the connector 15. be able to. As a result, the facing proximity overlapping connection of the wiring plate member 14 to the main wiring substrate 11 can be reliably performed with good workability, and the facing proximity overlapping connection of the wiring plate member 14 to the main wiring substrate 11 is achieved. It is possible to easily confirm that the above has been performed reliably.

  Furthermore, according to the wiring terminal connection device 10, the insulating housing 15 provided in the board-side connector 13 in which the fitting hole formed by the engaging portion 17 provided in the wiring plate-like member 14 is fixed on the main wiring board 11. When fitted to the outer periphery, the locking portions 24A and 24B provided in the board-side connector 13 protrude from the fitting hole in the wiring plate-like member 14 fitted to the outer periphery of the insulating housing 15, and the wiring plate-like member 14, the wiring plate member 14 is elastically engaged with the engagement recesses 37 </ b> A and 37 </ b> B provided in the peripheral portion of the fitting hole to lock the wiring plate member 14. The state of being electrically connected by the connection is maintained firmly and stably.

  The wiring terminal connection device according to the present invention as described above should be in a state where the wiring terminal portion provided on the wiring plate-like member such as a flexible printed wiring board is connected to the wiring terminal portion provided on the main wiring board. , Forming a board connecting mechanism for electrically connecting the wiring plate-like member to the main wiring board by face-to-face close overlapping connection, and having a thin overall structure including the main wiring board and the wiring plate-like member In addition, the facing and overlapping connection of the wiring plate member to the main wiring board can be reliably performed with good workability, and the facing and overlapping of the wiring plate member to the main wiring board can be achieved. It can be easily confirmed that the mating and coupling are performed securely, and the state in which the wiring board member is electrically connected to the main wiring board by the face-to-face overlapping coupling is stably maintained. As also possible to be so, but it can be widely applied to various electronic devices.
