Abstract

The utility model relates to improved structure of flexible circuit board connectors, which comprises a main body seat, two shims, a plurality of terminals, a movable cover, etc., wherein arc-shaped pivoting guide blocks of a plurality of linking grooves of a linking board of the movable cover are small arc convex parts which respectively hook and clamp every terminal. Thus, when a flexible circuit board is inserted and the movable cover is pivoted and restores an original position, action is smooth, the deformation or the split of the movable cover can not occur, and the movable cover can be pivoted and restores the original position with force saving. In manufacturing process, both side walls of the main body seat can be tried to be correspondingly extended forward and are shorter than a lower wall surface, and the intensity of both of the two side walls of the main body seat is increased further. Pivoting grooves of the utility model can be enlarged during manufacture, the central position can be tried to be moved backwards for matching the movable cover which has a bigger pivoting diameter and a backward moved center, and the occurrence of the split of both of the two side walls or a pivoting shaft of the movable shaft can be reduced.

Description

Soft Circuit Board Union improves structure

Technical field

The utility model relates to a kind of Soft Circuit Board Union.

Background technology

General flexible circuit board weldering is established when being fixed in the circuit board top usually different and must adopt vertical connector or horizontal connector along with the superjacent air space form utilization of the circuit board of difference in functionality, and the removable cover of horizontal Soft Circuit Board Union when opening because angle is little, the operating space was little very inconvenient when therefore the flexible circuit board desire was inserted in the connector body, though this kind shortcoming can solve by this connector the place ahead of welding, circuit board top is vacated than large space, but taken the space of circuit board thus again, making every effort to product short and small very thin today, this kind solution also can't be widely adopted.

Moreover, please be in addition with reference to figure 1, connector shown in Figure 2, the direct contact tappet 811 of application of force extruding flexible circuit board 9 and the contact arm 81 of terminal 8 when flexible circuit board 9 inserts (with reference to figure 1) and removable cover 90 and returns to original position downwards, contacting between therefore operation painstaking (with reference to figure 2), and flexible circuit board 9 and the contact tappet 811 gets loose easily and causes the situation of loose contact.

Inferior looking into, the both sides pivot system of the removable cover of general Soft Circuit Board Union is hubbed on the pivot connected slot of noumenal seat two side, and the external diameter of the pivot of removable cover usually can not be too big, otherwise rupture easily in the two side of noumenal seat, and the center of pivot also can not be too to rear direction, otherwise the effect of urgent terminal can be influenced when removable cover was closed, therefore removable cover causes the pivot fracture easily or causes the two side fracture of noumenal seat and cause defective products when using when closure, and removable cover system leans all terminals of interlock by its interlock plate during aforementioned closed action, therefore need bigger strength operate, and the easier inconvenience that causes removable cover when pivoting, to produce distortion and cause the user to operate when numbers of terminals is a lot.

Summary of the invention

The purpose of this utility model is to provide a kind of improvement structure of Soft Circuit Board Union, and it has more firm electrical contact, and production cost is low, and can reduce the generation of the pivot fracture situation of two side or removable cover relatively.

For achieving the above object, a kind of Soft Circuit Board Union of the utility model improves structure, comprise: a noumenal seat, system is respectively equipped with some caulking grooves for being embedded plurality of terminals respectively, and noumenal seat also has an intercalation space that is communicated with aforementioned each caulking groove, the two side of this noumenal seat then can be for being pivoted a removable cover, and the in addition default draw-in groove in these noumenal seat both sides can supply the intercalation location of the inserting part of pad in addition; Two pads are respectively to have inserting part can go in two side bayonet slots of noumenal seat for intercalation, and inserting part and extend a fixed part can be for fixing with the predetermined position welding of circuit board; Plurality of terminals, be that its support arm of mat and contact arm are embedded in each caulking groove of the rear side of noumenal seat respectively, the inside front of its contact arm then has contact tappet, then have linking arm between contact arm and the support arm, the below side of this linking arm then has fixed arm can be for fixing with the circuit board welding; One removable cover, rear side is an interlock plate, be to be that both sides tool pivot can be for the pivot connected slot of the two side that is hubbed at noumenal seat, the intercalation space that flexible circuit board can insert noumenal seat when removable cover outwards pivots unlatching can electrically be contacted with the contact tappet of the contact arm of aforementioned each terminal by its interlock plate interlock flexible circuit board when the removable cover pivot returns to original position again; This plurality of terminals, side-lower is the tool breach and forms a little arc protuberance in its each support arm, makes the support arm inboard of each terminal can insert in each linked slot of interlock plate of removable cover, but and just make its little arc protuberance dogging in the last ora terminalis of each arc pivot guide block; This removable cover, side-line is offered some linked slots at a distance of suitable distance behind its interlock plate, and also respectively has arc pivot guide block in each movement slots, the both sides of its interlock plate then form highly slightly high blocks, the side of this blocks then has aforementioned pivot, and the big and center of the diameter of this pivot is also towards rear side, and the front end of the both sides of this interlock plate then respectively is provided with fixture block, and the two side ends of the front side of this removable cover respectively has the front side of short slot with the two side of avoiding interfering noumenal seat; This noumenal seat, its both sides are to be arranged with the horizontal line of rabbet joint and the vertical line of rabbet joint, make its two side have suitable elasticity, and its front side, two side is the guiding incline that symmetry has draw-in groove and is connected this draw-in groove, and guiding incline also extends a planar portions and is connected with pivot connected slot backward, the upper wall surface of noumenal seat system is shorter than its lower wall surface in addition and both sides form recess, and the length of the two side of this noumenal seat system is slightly less than the length of lower wall surface, can move more backward in the position of making the pivot connected slot of aforementioned two side when producing relatively with cooperate articulate removable cover than major diameter and the center pivot after partially;

Owing to adopted such scheme, the utility model removable cover can be inserted and be assembled with noumenal seat by horizontal direction, insert respectively by the pivot of the both sides arc piece of the interlock plate of removable cover noumenal seat the two side draw-in groove and import pivot connected slot along the work guiding incline to the Hou slippage, but and make arc pivot guide block dogging in each linked slot of its interlock plate against the little arc protuberance of the breach below of the support arm of each terminal, and the fixture block of the both sides of this interlock plate is with assembling the location in the draw-in groove that can snap in the noumenal seat two side; Be with when going into flexible circuit board, but opening, the firm pivot of arc piece of its both sides of removable cover mat and pivot is the big opening angle about 90 degree, with can easily flexible circuit board being inserted, the right Hou reversion original position that again removable cover oppositely pivoted can make the bottom face of interlock plate compress flexible circuit board and electrically contact with the contact tappet of the contact arm of terminal.
