Description

[Detailed Description of the Invention] This invention relates to a flexible printed circuit board used in communication equipment, electronic equipment, etc.

In recent years, printed circuit boards have been widely used in communication equipment and electronic equipment, and it is possible to connect and disconnect the ends of these boards and the terminals of operating parts or electronic parts provided in the equipment casing etc. using a connector method (plug-in connection). May be freely connected.

In this case, since the flexible printed circuit board itself is made of a film-like soft material that has no stiffness, when inserting this flexible printed circuit board into the plug-in connector, it is easy to bend, so it is difficult to insert it, and it is difficult to remove it. It was also difficult to pick and remove because it had no waist.

In view of such conventional optical transfer, the present invention involves attaching a hard insulating plate to one or both sides of the end of the flexible printed circuit board, and inserting holes for tools and jigs into this plate. A plurality of holes are formed in the connector so that the connector can be easily inserted into the connector, and the connector can be easily picked up using a tool such as tweezers or a jig so that handling such as removal can be easily performed.

To explain the present invention in detail with reference to the drawings, reference numeral 1 denotes a flexible substrate made of polyester resin or the like, and a printed wiring network 2 is formed on one or both sides of the flexible substrate.

Reference numeral 3 denotes a narrow splint plate attached to the end of the flexible substrate 1. The splice plate 3 is made of an insulating material like the substrate 1, and is made of a harder plate than the substrate 1.

As an example of the splice plate 3, a plurality of jig holes 4, 4 are bored at both ends thereof.

In the illustrated embodiment, the splice plate 3 is attached only to the front side of the substrate 1, but it may be attached to the back side.

Since the flexible printed circuit board of the present invention has the above-mentioned configuration, when connecting this board to operating parts or electronic parts provided in the casing of electronic equipment, etc., use a connector as shown in Figure 2. The board 1 with the splicing plate 3 attached in advance is inserted into the socket hole 5 provided at C.

In this way, the board itself is prevented from bending when the board 1 is inserted, and the end of the board can be inserted into the socket hole 5 extremely smoothly, improving workability.

Furthermore, since the base plate 1 is not easily bent due to the presence of the splicing plate 3, it is possible to maintain a sufficient contact area and contact force with the terminal, thereby improving the stability and reliability of the crimp contact portion.

Further, as shown in FIG. 3, according to the present invention, since a plurality of jig holes 4 are provided at appropriate locations on the splice plate 3, it is easy to pick the connector with a tool jig 6 such as tweezers. It can also be easily inserted and removed.

As described above, although the present invention has a simple structure, it has great practical effects.
