Description

TECHNICAL FIELD

[0001] The utility model relates to circuit board technical field especially relates to a kind of FPC connectors of adjustable plugging force. BACKGROUND

[0002] FPC in use, since the gold finger on FPC connector is relatively fragile, it is easy to scratch and damage during plugging, therefore, FPC gold finger end is usually installed on FPC connector plugging piece. However, the FPC of the existing FPC connector is usually clamped and positioned on the FPC connector, and when the FPC is subjected to external force, the gold finger of the FPC can be directly stressed to the position of the gold finger, thereby there are problems of scratching and damaging the gold finger and easily loosening between the gold finger and the plastic main body. In addition, during use, the FPC connector that needs to be plugged in and out multiple times has the problem of not being easy to pull out. If the plugging gap between the FPC connector and the electronic device is set to be loose, the problem of not being easy to pull out can be solved. However, when applied in an environment with external forces such as vibration and jolt, the connector has the problem of easy loosening, and the practicability is poor. SUMMARY

[0003] Therefore, it is necessary to provide an FPC connector with adjustable plugging force in view of the deficiencies in the prior art.

[0004] An FPC connector with adjustable plugging force includes a connector and an FPC. The connector includes a main body, an inner contact terminal and an outer plug-in terminal arranged on the main body. The inner contact terminal is electrically connected with the outer plug-in terminal. The main body is provided with a plug-in part and a mounting part arranged oppositely. The outer plug-in terminal is arranged on the plug-in part. The mounting part is provided with a first limiting part and a second limiting part. The first limiting part is provided with a limiting hole and a positioning piece. The bottom outer end of the limiting hole is extended to be provided with a bottom plate. One end of the gold finger of the FPC is inserted into the limiting hole. The positioning piece penetrates from the top outer side of the limiting hole and abuts against the top surface of the FPC. The gold finger of the FPC contacts with the inner contact terminal. The second limiting part is arranged on the bottom plate, and the second limiting part presses the FPC.

[0005] Further, the positioning piece includes a bolt and an extension spring. The extension spring is sleeved outside the bolt. The bolt is arranged on the main body and extends into the limiting hole. The bottom end of the bolt and the extension spring abut against the top surface of the FPC.

[0006] Further, the top hole wall of the limiting hole is provided with a positioning hole, and the bolt is screwed into the positioning hole.

[0007] Further, the bottom end of the bolt is provided with a buffer pad. The outer diameter of the buffer pad is greater than the outer diameter of the bolt rod.

[0008] Furthermore, the telescopic spring is tapered, with a smaller top and a larger bottom, and the top of the telescopic spring is positioned on the bolt.

[0009] Furthermore, the second limiting part is disposed on the outer end of the base plate. The second limiting part includes a top plate and a limiting bottom plate. One end of the top plate is pivotally connected to one side of the limiting bottom plate, and the other end of the top plate is installed on the other side of the limiting bottom plate.

[0010] Furthermore, a soft pad, which is made of silicone material, is provided on the bottom surface of the top plate.

[0011] Furthermore, the main body is made of plastic.

[0012] In summary, the FPC connector of this utility model, by setting a first limiting part and a second limiting part, with the first limiting part limiting the gold finger end of the FPC and the second limiting part located outside the first limiting part, prevents external force from directly impacting the gold finger end when the FPC is subjected to external force, reducing the risk of the FPC becoming loose or the gold finger end being scratched or damaged. The movable limiting component allows for adjustable insertion and extraction force during use, broadening its applicability. This utility model is highly practical and has significant potential for widespread application. Attached Figure Description

[0021] The second limiting portion 115 is arranged on the outside end of the bottom plate 122, and the second limiting portion 115 includes top plate 121 and limiting bottom plate, one end of the top plate 121 is pivoted (similar to the hinge mode of opening door and window) on one side surface of the limiting bottom plate 122, and the other end of the top plate 121 is installed on the other side surface of the limiting bottom plate.The installation mode of the other end of the top plate 121 is the clamping mode of conventional clamping block clamped into clamping groove type, or hook limiting or other conventional mode, which can be fixed;for example, the clamping block extends downward on the top plate 121, and the clamping groove is arranged on the top of the side surface of the limiting bottom plate, and the clamping block is embedded in the clamping groove.In addition, the bottom surface of the top plate 121 is provided with soft pad, and the soft pad is made of silica gel material.
