Description

  The invention described in the claims of the present application is a state in which the two wiring boards are electrically connected to the wiring terminal portions provided on the respective wiring boards in a state where the two wiring boards are superimposed in close proximity to each other. The present invention relates to a wiring board coupling device that couples both wiring boards.

  A relatively small electronic device such as a cellular phone also includes a large number of various electronic components. Many of these electronic components are mounted on a plurality of wiring boards and perform their functions. A plurality of wiring boards on which various electronic components are mounted, for example, when viewing two of them, the occupied volume should be as small as possible when accommodated in a limited space inside a relatively small electronic device. Therefore, it is inevitable that one is superposed in close proximity to the other and is interconnected. Hereinafter, a connection mode in which one of the two wiring boards is superimposed on the other in close proximity to each other will be referred to as facing close overlapping connection.

  In general, interconnection of a plurality of wiring boards, each of which is a flexible printed wiring board (FPC) or a solid wiring board, is performed by attaching a connector to each wiring board and interconnecting the connectors. In many cases, it is conceivable to use a connector attached to each wiring board even when two-sided wiring boards are connected in close proximity. Conventionally, several board connection apparatuses including connectors for performing face-to-face close overlapping connection of two wiring boards have been proposed (see, for example, Patent Document 1).

  The board connecting device disclosed in Patent Document 1 is based on the fact that the first wiring board (printed circuit board (6)) and the second wiring board (printed circuit board (16)) are subjected to face-to-face close overlapping connection. The first connector (receptacle connector (1)) attached to the first wiring board and the second connector (plug connector (11)) attached to the second wiring board are configured. The first connector includes a housing (insulator (2)) and a plurality of first contacts (contacts (3)) arranged in the housing, and the second connector includes a housing (insulator (12)). ) And a plurality of second contacts (contacts (13)) arranged in the arrangement. In addition to the plurality of first contacts, the first connector housing is attached with a reinforcing bracket (fitting lock and fixing holddown (4)) provided with an elastic lock (4B). In addition, the housing of the second connector includes a plurality of second contacts, in addition to a plurality of second contacts, a lock fitting (14A1) provided with a reinforcing bracket (fitted and locked holddown (14 )) Is installed.

  Under such circumstances, the surface of the second wiring board to which the second connector is attached is opposed to the surface of the first wiring board to which the first connector is attached. A state is obtained in which the board is superposed on the first wiring board in close proximity to each other, whereby the housing of the first connector and the housing of the second connector are interfitted, and the second connector The plurality of second contacts disposed in the housing are disposed in the housing of the first connector and are in press contact with the plurality of first contacts, respectively. As a result, the plurality of first contacts included in the first connector and the plurality of second contacts included in the second connector are interconnected so that the first wiring board and the second wiring board face each other. Proximity overlay connection is performed.

  In this case, when the housing of the first connector and the housing of the second connector are fitted to each other, the lock portion (4B) in the reinforcing bracket attached to the housing of the first connector is temporarily in the second position. After receiving deformation due to the contact pressure of the connector housing, it tries to return to its original state by its own elastic restoring force, so that the lock receiving portion in the reinforcing metal fitting attached to the housing of the second connector ( 14A1) is engaged while applying an elastic pressing force. In this way, the lock portion (4B) in the housing of the first connector is engaged with the locked receiving portion (14A1) in the housing of the second connector while applying an elastic pressing force, whereby the second connector. Therefore, it is expected that undesired detachment of the second connector housing from the first connector housing is prevented.

  In the board connecting device disclosed in Patent Document 1, the lock portion (4B) in the housing of the first connector is formed with the housing of the first connector and the housing of the second connector being fitted to each other. By engaging the lock receiving portion (14A1) in the housing of the second connector while applying an elastic pressing force, the lock portion (4B) is engaged with the housing of the second connector. The locking of the second connector to the housing by using the elastic restoring force by the lock portion (4B) is adversely affected by the temporal change of the lock portion (4B). The lock portion (4B) constitutes a part of a reinforcing metal fitting attached to the housing of the second connector, and the reinforcing metal fitting is formed, for example, by processing an elastic metal plate. Therefore, the lock portion (4B) forming a part of the reinforcing metal fitting causes a decrease in elastic restoring force due to its secular change as a so-called “sagging”, and the engagement with the housing of the second connector. There is a risk of causing inconvenience in stopping.

  Under such circumstances, when the lock portion (4B) forming a part of the reinforcing metal fitting causes a “sag” that reduces the elastic restoring force with the passage of time, the housing of the first connector and the second connector When the housing (4B) is interfitted with the housing, the lock portion (4B) is once deformed by receiving the contact pressure from the housing of the second connector and then returning to its original state by its own elastic restoring force. When this occurs, the elastic restoring force is reduced, so that a sufficient restoration state cannot be obtained, and the lock receiving part (14A1) in the reinforcing bracket attached to the housing of the second connector is secured to the lock part (4B). It is not possible to properly obtain the state of engaging while applying an elastic pressing force. As a result, the locking of the second connector to the housing by the lock portion (4B) is not properly performed.
