[0009]

In the above-described electrical connector of the first invention,
By sandwiching the terminal of the FPC between the socket member and the lateral side of the plug member, the lateral side of the plug contact pin is pressed against the terminal of the FPC and the vertical side of the plug member is inserted into the socket member. By doing so, the vertical side of the plug contact pin is pressed against the socket contact pin, so that the connection work between the plug contact pin and the terminal portion of the FPC does not require any troublesome work such as soldering. It can be done simply and easily.

In the above-described electrical connector of the second invention, the plug cover is disposed to face the side of the plug member, and the terminal of the FPC is sandwiched between the plug cover and the side of the plug member. Therefore, the connection work between the plug contact pin and the terminal portion of the FPC can be performed at a place away from the socket member mounted on the printed wiring board. This can be performed very easily as compared with the case where it is applied to the socket member, and after the FPC connection operation is completed, if the vertical side of the plug member is inserted into the socket member, the entire connection operation is completed. Since the connector is assembled in this manner, a series of connection operations can be performed smoothly and rationally.

In the electrical connector according to the third aspect of the present invention, two FPCs are separately inserted into the left and right spaces formed between the plug member and the plug cover, respectively, so that they can be sandwiched simultaneously. Therefore, even when two FPCs are connected to the board, only the one electrical connector is sufficient, so that the space for mounting the electrical connector can be reduced as compared with the case where two electrical connectors are used. At the same time, labor and man-hours are reduced by half.
