Description

Flexible circuit board connection structure

Technical Field

The utility model relates to the technical field of circuit board pressing, in particular to a flexible circuit board connecting structure.

Background

The flexible printed circuit board is characterized by light weight, thin thickness, flexibility and flexibility, and is mainly used in electronic products such as mobile phones, notebook computers, PDAs, digital cameras, liquid crystal display screens and the like. The average stress of the connecting edge of the existing golden finger is large when the golden finger is plugged and pulled out, the product is scrapped due to the fact that the contact position of the product is inaccurate due to the fact that the golden finger is bent and broken or the insertion depth is insufficient due to the fact that the inserting depth is not clear and the force is excessive during inserting, and therefore the contact is poor, the user is wasted greatly, especially under the condition that the flexible circuit board is required to be pulled out frequently, at present, the FPC flexible circuit board needs to be replaced wholly after being damaged, resources are wasted, and the flexible circuit board is troublesome to disassemble.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned drawbacks of the prior art, the present invention provides a flexible printed circuit board connection structure.

The technical scheme adopted by the utility model is as follows: the utility model provides a flexible line way board connection structure, the key lies in: including the FPC main part and setting up the golden finger of FPC main part tip, the FPC main part with the junction cover of golden finger is equipped with the joint cover, just about the joint cover interior anchor ring face just to seting up flutedly, two all the activity is equipped with horizontal butt joint board in the recess, the tank bottom of recess with correspond horizontal butt joint board passes through the elastic component and connects, the both sides of FPC main part are equipped with the limiting plate respectively. The effect of this scheme is that can realize the quick assembly disassembly of golden finger and FPC main part through the joint cover, avoids damaging because of the golden finger and leads to whole circuit board to the joint cover can restrict golden finger male degree of depth when golden finger is pegged graft with external power source, avoids leading to the fact the cracked condition of golden finger because of inserting the improper dynamics.

Preferably, the connecting edge of the FPC main body and the golden finger is a wavy line. The effect of this scheme has increased the length of connecting the limit, has reduced the average atress of golden finger on the limit department when the plug for the connecting edge of golden finger has higher intensity when being in the plug.

Preferably, the horizontal abutting plate is made of a rubber material. The effect of this scheme is the fastening degree of being connected of improvement joint cover and FPC main part.

Preferably, the elastic part is a plurality of springs arranged in parallel, and two ends of each spring are respectively and fixedly connected with the inner surface of the horizontal abutting plate and the groove bottom of the groove. The effect of this scheme is the connection tightness of further improvement golden finger and FPC main part.

Preferably, the limiting plate is made of an insulating material.

Has the advantages that: compared with the prior art, the flexible circuit board connecting structure provided by the utility model changes the traditional circuit board mounting mode, can realize the quick disassembly and assembly of the circuit board and the golden finger as required, can be accurately inserted according to the required depth without careful identification in the plugging process, can not cause the replacement of the whole circuit board due to poor contact of the golden finger, saves resources and has wide market prospect.

Detailed Description

In order to make the technical solutions of the present invention better understood, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Example 1

As shown in fig. 1, a flexible line way board connection structure, be in including FPC main part 1 and setting the golden finger 2 of 1 tip of FPC main part, FPC main part 1 with the junction cover of golden finger 2 is equipped with

joint sleeve

3, 3 internal planes of joint sleeve are just to offering groove 4, two from top to bottom all the activity is equipped with horizontal butt joint board 5 in the recess 4, the tank bottom of recess 4 with correspond horizontal butt joint board 5 passes through elastic component 6 and connects, the both sides of golden finger 2 are equipped with limiting plate 7 respectively, limiting plate 7 is made by insulating material.

Example 2

As shown in fig. 1-3, a flexible printed circuit board connection structure comprises an FPC main body 1 and a gold finger 2 disposed at the end of the FPC main body 1, the connecting edge of the FPC main body 1 and the gold finger 2 is a wavy line, a joint sleeve 3 is sleeved at the joint of the FPC main body 1 and the gold finger 2, the inner annular surface of the joint sleeve 3 is attached to the surface of the FPC main body 1, grooves 4 are formed in the inner annular surface of the joint sleeve 3, horizontal abutting plates 5 are movably disposed in the two grooves 4, the horizontal abutting plates 5 are made of rubber materials, the groove bottom of each groove 4 is connected with the corresponding horizontal abutting plate 5 through elastic members 6, each elastic member 6 is a plurality of springs arranged in parallel, the two ends of each spring are fixedly connected with the inner surface of the horizontal abutting plate 5 and the groove bottom of the groove 4, and limiting plates 7 are disposed on the two sides of the gold finger 2, the limiting plate 7 is made of an insulating material.

The working principle is as follows: during the use, the wavy line connection limit of golden finger is pasted tightly with the terminal surface of FPC main part, then embolias the joint cover from the golden finger, until limiting plate and joint cover butt, under the effect of spring, horizontal butt joint board and FPC main part and golden finger surface fastening joint realize the quick erection joint of golden finger and FPC main part.

Finally, it should be noted that the above-mentioned description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and scope of the present invention.
