Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

As shown in fig. 1 to 6, the electrical connector 100 of the present embodiment has a flat cable terminal 200, and the flat cable terminal 200 is disposed in the FPC electrical connector 100 to serve as a grounding terminal, and is connected to the bottom line on the back of the FPC, so as to achieve a shielding effect.

As shown in fig. 2, the flat cable terminal 200 is disposed at the left and right sides of the electrical connector 100 and fixed by using a plastic body, and the flat cable terminal 200, specifically, the flat cable terminal 200 includes a terminal body 210, a cantilever 220 and a flanging force arm 230, the terminal body 210 is substantially a pin structure and is disposed along the plugging direction of the electrical connector 100, the cantilever 220 is formed by bending the upper side of the terminal body 210, and obtains a certain height in the electrical connector 100, the flanging force arm 230 extends from the cantilever 220 and is disposed along the direction perpendicular to the terminal body 210, and forms a contact point 231 at a position lower than the height of the cantilever 220 by its own torsion, and the torsion angle of the flanging force arm 230 is smaller than 90 degrees.

In the process of twisting the flanging force arm 230, the twisting degree of the flanging force arm 230 is gradually increased along the length direction, and finally the lowest point is obtained at the end part of the flanging force arm 230 and is used as a conduction point with the flat cable, when the flat cable is inserted, the pressure of the flat cable acting on the contact point 231 is offset by the deformation elastic force generated by the bent cantilever 220, the elastic force caused by the height difference of the two ends of the flanging force arm 230 and the torsion of the flanging force arm 230. Therefore, the force acting on the burring force arm 230 is dispersed, which brings about the advantage that the burring force arm 230 is not easily deformed beyond its limit, and the structural strength is enhanced.

On the other hand, the elastic arm formed by the torsion of the flanging arm 230 can be regarded as reinforcing the thickness of the material compared with the elastic arm obtained by the traditional bending deformation, so that higher structural strength can be obtained.

As a further improvement, in this embodiment, the flanging arm 230 has a double-arm structure, and the prototype thereof is a U-shaped sheet integrally connected to the cantilever 220, and a torsion structure with a V-shaped or U-shaped cross section is formed by punching and flanging the center line of the stamping die, so as to obtain a height difference and achieve the purpose of elastic contact.

The flanging force arm 230 obtained by the method comprises a pair of side force arms 232 which extend out from the cantilever 220 and are twisted, the front ends of the side force arms 232 are combined into a whole, and the side force arms 232 are symmetrically arranged to resist the pulling and inserting acting force of the flat cable together.

The outer side surface of the flanging force arm 230 with the V-shaped cross section forms a guide inclined surface 233 facing the plugging direction, when the flat cable is plugged into the connector, the head of the FPC is contacted with the V-shaped (or U-shaped) side surface of the flanging force arm 230, and the flanging force arm 230 floats upwards after being stressed until the grounding surface of the flat cable is contacted with the contact point 231 and is in conductive connection with the FPC flat cable.

The V-shaped structure connects the double-force-arm structure into a whole, so that the anti-jacking force capability is improved.

In the flanging force arm 230 with the double-force-arm structure, the two side force arms 232 are arranged oppositely, when the external force from the flat cable is received, the two side force arms are twisted towards the middle, but the two side force arms are limited by the end parts of the two side force arms which are combined into a whole, the external force received by the two side force arms can be mutually offset, and the structural strength of the flanging force arm 230 is further enhanced.

From the angle of production, form two power arm structures through punching press is tensile, turn-ups, and its self resilience stress can offset by oneself, and the shaping degree is better, reduces the punching press complexity, increases terminal structural stability.

In this embodiment, the flanging force arm 230 is perpendicular to the plugging direction, i.e. disposed along the length direction of the finished product of the electrical connector 100, so as to save space resources in the width direction of the finished product, which is beneficial to the miniaturization of the device.

More specifically, the flanging force arm 230 is arranged along the insertion direction of the flat cable, and the edge of the side force arm 232 naturally forms a smooth guiding bevel 234 by the torsion of the side force arm 232, so as to be used for guiding the flat cable in an inserting manner.
