Description

Connector device for substrate connection

The present invention relates to a connector device for substrate connection for connecting a substrate and a substrate, a substrate, and a flexible printed substrate (FPC).

Conventionally, in the connection between a substrate and a substrate, or the connection between a substrate and a flexible printed circuit (FPC), a connector for substrate connection is used. The connector for substrate connection includes a plug and a socket, and the plug has a plurality of side portions. The plug-like plug portions of the plug-side signal terminals are provided with a plurality of socket-side signal terminals on the inner side faces of the plug insertion slots into which the plug portions are inserted.

In the board connecting connector, a female side guide portion having a concave hole-shaped guide hole is provided at each end portion of the socket, and a male side fitted to the guide hole is provided at both end portions of the plug to be guided. When the male side guide body is guided to the guide hole, the plug portion is fitted so that the plug portions are fitted at desired positions of the plug insertion grooves, and the two signal terminals are in contact with each other (for example, refer to Patent Document 1).

In such a board connection connector, in order to smoothly insert the male side guide body into the female side guide portion, the fitting tolerance of the guide hole and the male side guide body is set to a constant margin, and The upper opening edge portion of the female side guide portion is formed into a tapered guide portion, and a tapered guide portion is formed on the lower peripheral edge portion of the male side guide body. When the socket and the plug are connected, the two guide portions are in contact with each other. By sliding from this state, the guided body is guided to the female side guide portion, and the positional deviation in the longitudinal direction and the short direction of the socket and the plug can be absorbed.

The size of the connector for substrate connection is, for example, 2.3 mm in width × 4 mm in length, which is very small compared to the size of the substrate or the FPC. Therefore, there is a problem that alignment between the plug and the socket is extremely difficult. Moreover, the fitting portion of the plug and the socket is hidden by the substrate, the FPC, or the like. Since it cannot be visually confirmed, it is a problem that a fitting operation becomes a blind work, and it takes time to insert, and a plug or a socket is damaged.

In order to solve such a problem, it is possible to improve the alignment accuracy by causing the end portion of the plug to protrude from the end surface of the substrate or the FPC to form a visible position. However, the position protruding from the end surface of the substrate or the FPC is often penetrated to The socket is fitted to the side, and therefore, it is feared that the end of the plug is broken.
