Abstract

PURPOSE:To insert a connector without interference with a printed board by providing a contact part composed by peeling one side end part of an insulating film and a stiffening plate being stuck to the insulating film on the opposite side surface to the contact while having projections on both sides. CONSTITUTION:In an FPC holding both sides of a conductor 6 between the insulating films 4, 5, one side end is peeled to provide a contact 1. Since the FPC 8 is structutally apt to be bent while being short of strength at the part of a contact 1 and unable to be inserted into a connector, a contact reinforcing plate 7 is attached in the sense of reinforcement. Then, the insertion auxiliary holes 2, 3 are provided on both sides of this contact reinforcing plate 7. The FPC connector 10 is the connector to join the FPC 8 with the printed board 9. The FPC 8 can be inserted into the FPC connector 10 straight, with applying no unreasonable force.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a flexible printed circuit board (hereinafter abbreviated as FPC).

Conventional technology In recent years, the demand for RPC has been increasing as electronic devices have become smaller.Especially in small VTRs, the configuration of the contact section that connects the FPC and other boards has made it easier to assemble the device. It is becoming important from this point of view.

In the conventional RPC, as shown in Fig. 4, the insulating film 4 at the end of the YPC, which has insulating films 4 and 5 on both sides, is peeled off to serve as a contact point, and a rectangular reinforcing plate 7 is attached to the opposite side. there were.

FIG. 5 is a diagram showing a state in which the conventional FPCB configured as described above is inserted into the connector 1o and attached to the printed circuit board 9.

Problems to be Solved by the Invention However, in the conventional RPC configured as described above, when inserting the connector 10KFPCB, points A and B in Fig. 5 are operated by sandwiching them between the fingers. Since it hit the lower printed circuit board 9, it was not possible to insert one into the FPC connector 10 immediately, and it had to be inserted while bending a little like 0, which caused extra force to be applied to the FPC 8, making it difficult to insert. .

In view of this point, the present invention aims to provide a flexible printed circuit board that can be easily inserted straight into a connector.

Means for Solving the Problems The present invention provides a flexible printed circuit board in which a conductor is sandwiched between insulating films on both sides. It is characterized by comprising a reinforcing plate attached to an insulating film and having protrusions formed on both sides.

Function: With the above-described structure, the present invention utilizes the protrusion to insert the connector straight into the connector without applying excessive force.

Embodiment FIG. 1 shows an embodiment of the RPC of the present invention. 1st
In the figure, reference numeral 1 indicates a contact, which is obtained by peeling off the end of one side (the insulating film 4 in FIG. 1) of an FPC in which both sides of a conductor 6 are sandwiched between insulating films 4.5. Because the FPC 8 is easily bent due to its structure and the strength of the contact 1 portion is insufficient, it cannot be inserted into the connector, so a contact reinforcing plate 7 is attached for reinforcement. Further, insertion auxiliary holes 2.3 are provided on both sides of this contact reinforcing plate.

Insertion of the ypcs of this embodiment configured as described above into the connector will be explained using FIG. 2.

Figure 2 is a connector insertion diagram, and the FPC described in Figure 1
8'i is a diagram showing how it is attached to a printed circuit board 9. 1o is an FPC connector, which is a connector for connecting the FPC 8 and the printed circuit board 9. 11 is a bottle set, insert both sides into the auxiliary insertion hole 2.3 and insert the FP.
I use it as a tool to insert it into the C connector 1°.

As shown in FIG.
PCi8 easily FPs straight and without applying excessive force.
This means that it can be inserted into the C connector 1o.

In the first embodiment, two insertion auxiliary holes were made in the contact reinforcing plate, but it is also possible to simply provide protrusions on both sides as shown in FIG.

As described above, according to this embodiment, it is possible to easily insert the FPC straight into the connector using the protrusions of the contact reinforcing plate.

Effects of the Invention As described above, according to the present invention, the connector can be inserted without being obstructed by the printed circuit board, and its practical effects are extremely large.
