It has a groove 18, and parallel to the groove 18 is a flat cable and a connector body 13 in FIG.
In order to stabilize the pressure contact with the U-shaped connector part 11 located on the back side, it has a wall 19 with a height equal to the thickness of the flat cable, and also has a wall 19 with a height equal to the thickness of the flat cable. It has an escape hole 20 for the connection terminal 9 to prevent contact with the connection terminal 14.

Further, the upper lid 12 has the same shape as the lower lid 14.

In the upper cover 12 and lower cover 14, the flat cable and the U
It is installed so that the grooves 18 for ensuring pressure contact with the letter-shaped connector part 10.
The guide pins 15 of the upper cover 12 and the holding holes 17 of the lower cover 14 fit together, two each, and the holding holes 17 of the upper cover 12 and the holding holes 17 of the lower cover 1 are fitted.
It is press-fitted so that it fits with the guide pin 15 of No. 4.

In this way, the flat cable branch connector 6 is formed.

From FIG. 5 to FIG. 9, application examples of the flat cable branching connector will be explained by way of example, and all of these application examples use the connection terminals shown in FIG. 3a.

FIG. 5 shows a connection form between a main flat cable 7 and a branching flat cable 8 to which the flat cable branching connector 6 of the present invention is applied.

That is, the core wire 7a of the basic flat cable 7 is connected to the connection terminal 9.
The core wire 8a of the branching flat cable 8 is press-contacted to one of the U-shaped connector parts 11a to be electrically connected.

Therefore, the signal of the core wire γa of the main flat cable 7 is transmitted via the connecting terminal 9a to the core wire 8a of the branch flat cable 8.
