Abstract
The utility model relates to a terminal for flexible circuit boards, which comprises long fingers and short fingers which are mutually staggered and arranged. The free end of the long finger is longer than the free end of the short finger; wherein, the free end of the short finger extends to the direction away from a flexible circuit board body and forms a short inducing plate. With the structure, the force bearing area of the flexible circuit board terminal in a bending place is enlarged; the bending place of the terminal is not easy to be fractured after the force being dispersed.
Description
Technical field
The utility model relates to a kind of flexible circuit board, especially relates to a kind of flexible circuit board terminal.
Background technology
Existing flexible circuit board (FPC) can be produced list, and is two, multiple-plate structure.Wherein more flexible circuit board all has the terminal of the finger-shaped shown in Fig. 1, and this terminal is used for contacting with other connector, thereby realizes the conducting of circuit.This terminal comprises that the long finger and the short hand of interlaced arrangement refer to that the free end of long finger grows the free end that short hand refers to.This terminal is that the emphasis of whole flexible circuit board is made part.To the existing general manufacture method flow process in this terminal place be: 1. earlier the whole etching of circuit is come out; 2. window at the PI of this terminal place, that is: be uncovered film herein and cover; 3. the terminal place is carried out surface treatment, one deck nickel gold is enclosed at the terminal place, the circuit of protection terminal is not oxidized; 4. at the back side of terminal corresponding position lamination reinforcement plate.
When this type of FPC and connector assembling, often need insert on the double flat ground, free end place that short hand refers in the connector, and when assembling may cause fracture through the circuit of terminal bending place, plug back repeatedly, causes not conducting of circuit, and connector is with on FPC can not be connected.
The utility model content
The circuit that the technical problems to be solved in the utility model provides a kind of bending place that is connected with connector is the flexible circuit board terminal of easy fracture not.
For solving the problems of the technologies described above, a kind of flexible circuit board terminal of the utility model, the long finger and the short hand that comprise interlaced arrangement refer to, the free end of this length finger grows the free end that this short hand refers to, wherein, the free end that refers to of described short hand is further to extending to form short leader away from flexible circuit board body direction.
As a kind of improvement of the present utility model, wherein, the free end of described short leader grows the free end of described long finger.
As a kind of improvement of the present utility model, wherein, the free end of described short leader is shorter than the free end of described long finger.
As a kind of improvement of the present utility model, wherein, the free end of described short leader is concordant with the free end of described long finger.
As a kind of improvement of the present utility model, wherein, the free end of described long finger is further to extending to form long leader away from flexible circuit board body direction.
As a kind of improvement of the present utility model, wherein, the free end of described long finger is further to extending to form long leader away from flexible circuit board body direction; The free end of described long leader is concordant with the free end of described short leader.
As a kind of improvement of the present utility model, wherein, the free end of described long finger is further to extending to form long leader away from flexible circuit board body direction; The free end of described long leader grows the free end of described short leader.
As a kind of improvement of the present utility model, wherein, the free end of described long finger is further to extending to form long leader away from flexible circuit board body direction; The free end of described long leader is shorter than the free end of described short leader.
The utility model compared with prior art, a kind of flexible circuit board terminal of the utility model, because the free end that refers at short hand is further to extending to form short leader away from flexible circuit board body direction, the lifting surface area of the bending place of flexible circuit board terminal increases, disperse stressed after, the bending place of terminal just be not easy the fracture.
