Description

Connector device for substrate connection

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

Conventionally, in the connection between a substrate and a substrate, or the connection between a substrate and a flexible printed circuit board (FPC), a substrate connection connector has been used, which includes a plug and a socket. Each of the plug-side signal terminals has a convex-shaped plug portion, and the socket is provided with a plurality of socket-side signal terminals on opposite inner side surfaces of the plug insertion grooves inserted into the respective plug portions.

In this board connection connector, female-side guides having recessed guide holes are provided at both ends of the socket, and male sides fitted into the guide holes are guided at both ends of the plug. The male body is guided while being guided to the guide hole, and is inserted, so that each plug portion is fitted at a desired position of each plug insertion groove so that the two signal terminals come into contact with each other (for example, refer to Patent Document 1).

In such a board connection connector, in order to smoothly fit 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 certain margin. The upper opening edge portion of the female-side guide portion forms a tapered guide portion, and at the same time, a tapered guide portion is formed on the lower peripheral edge portion of the male-side guided body. When the socket and the plug are connected, the two guide portions contact each other. From this state, by being slid with each other, the guided body is guided to the female-side guide portion, and it is possible to absorb the positional displacement of the socket and the plug in the long and short directions.
