Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wiring board connecting connector for directly connecting the wiring of one printed wiring board to the wiring of another printed wiring board.

Conventionally, electrical connections between multiple wiring boards have been made through connectors provided on each wiring board and connected to the wiring of the board, so the connection part can be made smaller than the wiring board part. First, there is a drawback that the connector cannot be miniaturized as a whole, and the connector has the disadvantage that an expensive conductive material must be used to improve the electrical contact, resulting in high material costs.

The purpose of the present invention is to provide a wiring board connector that is free from such drawbacks and has high workability and reliability. A substantially U-shaped pressure piece 3 is fitted into the groove 2 to press the overlapping ends of a plurality of wiring boards together.

On the front side of the elongated insulating material 1 shown in FIGS. 1 to 4,
A groove 4 extending in the longitudinal direction is formed, and a hole 6 connected to the groove 2 formed on the inner surfaces of both side walls 5, 5 of the groove 4 is formed on the back surface thereof.

The approximately U-shaped pressure piece 3 that fits into the groove 2 has one end on the opening side longer than the other end, the other end is curved inward, and the tip is connected to the wiring board pressing part. And so.

Therefore, the pressure piece 3 is inserted into the hole 6 of the insulating material 1 with its opening side facing down as shown in the fourth figure, and fitted into the grooves 2, 2.
Next, a T-shaped locking piece 7 having a forked portion at the tip is inserted from one end of the insulating material 1 between the bottom of the groove 4 and the upright portion of the approximately U-shaped pressure piece 3, and The protrusion 8 of the part is connected to the both side walls 5,
The pressurizing piece 3 was fitted into the groove 2 of the insulating material 1 by being engaged with the end face of the insulating material 1.

One of the wiring boards shown in FIG. 5 is a flexible printed circuit board 10 in which an insulating film 9 is applied to the wiring parts except for the connection parts, and the other one is a printed circuit board 11 that does not deform. is provided with a protrusion 12 for position regulation, and a reinforcing member 13 for reinforcing the end portion is attached to the flexible printed circuit board 10, and a hole 14 that fits into the protrusion 12 is provided on the flexible printed circuit board 10.
Furthermore, both printed circuit boards 10 and 11 are provided with a notch 15 for regulating the position of the connector at the same position.

Next, the function of the connector of the present invention will be explained.

The printed circuit board 11 and the flexible printed circuit board 10
In order to connect each wiring to each other, a flexible printed circuit board 10 is stacked on the printed circuit board 11, and its hole 14 is fitted into the projection 12 to align the wiring connection parts of both boards 10 and 11 and temporarily fixed. .

Next, with the groove 4 of the connector facing the printed circuit board 10.11 side, the notch 15 of the Phnont board 10.11 is fitted into the partition wall 16 provided at the center of the insulating material 1, and the Phnont board 1
The lower surface of the printed circuit board 10.11 is placed on the lower horizontal side of the pressure piece 3, and the printed circuit board 10.11 is pushed into the opening of the pressure piece 3.

When the pressure piece 3 engages with the printed circuit board 10.11, it is installed in the groove 2 of the insulating material 1 so as to be located above the wiring connection part of the printed circuit board 10.11, so that both printed circuit boards 10
．． The connection portions 11 are pressed together by the lower horizontal side of the pressure piece 3 and the wiring board pressing portion at the tip of the upper horizontal side. A good electrical connection can be obtained evenly at the connection part.

In place of the pressure piece 3 shown in the figure, a pressure piece with various modifications may be used, such as having the entire upper horizontal side inclined downward and its tip serving as a wiring board pressing portion.

According to the present invention, the overlapping ends of a plurality of wiring boards are pressed against each other in a plurality of grooves 2 arranged in parallel along the longitudinal direction of a long insulating material 1 in a substantially U-shape. Since the pieces 3 are fitted together, the connecting part can be made smaller than the conventional wiring board connector, and there is no need to use expensive conductive materials to connect the wiring.
Material costs are low, and work such as soldering is not required, so workability is good and reliability is high.
