Abstract

The utility model discloses a soft circuit board connector which comprises an isolation body, a rotating cover and a pair of inserting posts, wherein the isolation body is provided with a side plate, a guiding groove is arranged in the side plate and the inserting posts are correspondingly inserted into the guiding groove. The rough middle part of each of the inserting posts upwards extends and forms a stopping part, a pivot groove is surrounded by the stopping part and the side plate of the isolation body and the upper end of the pivot groove is closed by the side plate. The bottom at both sides of the rotating cover is provided with cam rotating shafts which are accommodated in the pivot groove and are rotated in the pivot groove, thereby, the rotating cover which is correspondingly pivoted with the isolation body can be opened or closed with the isolation body. When the rotating cover and the isolation body are opened, the diagonal distance of the cam rotating shafts is greater than the vertical height of the pivot groove, thereby, the pre-used turnover of the rotating cover is prevented.

Description

Soft Circuit Board Union

Affiliated technical field

The utility model relates to a kind of Soft Circuit Board Union, relates in particular to a kind of cover-lifting type Soft Circuit Board Union.

Background technology

At present, flexible circuit board (Flexible Printed Circuit is called for short FPC) because of the flexural property of its height and frivolous design feature, is widely used in many electronic equipments.The common connector that is used to assemble flexible circuit board is divided into two kinds, drawer type and cover-lifting type.Compare, the latter uses more general.

Disclose No. 2002/0106924 in laid-open U.S. Patents application on August 8 in 2002 Christian era and disclosed a kind of existing cover-lifting type Soft Circuit Board Union, comprise insulating body, pivoting with a rotatable cover cooperates, and plurality of terminals is also accommodated in inside.Insulating body both sides front end is provided with first and fastens voussoir, and the rear end is provided with pivot connected slot.Rotatable cover both sides front end is provided with second and fastens voussoir, and the rear end is provided with rotating shaft, and rotating shaft is contained in the pivot connected slot of insulating body, and pivots in it.

Before the use, the rotatable cover of described existing Soft Circuit Board Union is in open mode.During use, outside flexible circuit board is inserted in the insulating body, then cover rotatable cover.At this moment, fasten fastening between the second fastening voussoir of voussoir and rotatable cover makes insulating body hold with the rotatable cover button to cooperate by first of insulating body, and then make rotatable cover replace flexible circuit board downwards, thereby the clamping flexible circuit board is in described existing Soft Circuit Board Union.

Yet, because the not sealing of the pivot connected slot of the insulating body of above-mentioned existing Soft Circuit Board Union upper end, so the rotating shaft of rotatable cover can freely pivot in pivot connected slot.Before using, when rotatable cover is in open mode, after the user inserts outside flexible circuit board in the insulating body, flexible circuit board is a touching rotatable cover slightly, rotatable cover promptly can overturn downwards, and at this moment, the user has to rotatable cover is opened, then can continue the insertion operation of flexible circuit board, this process has been brought inconvenience in many uses to the user.

The utility model content

The purpose of this utility model is to provide a kind of Soft Circuit Board Union, can prevent to rotate the upset that is placed on before using, thereby make things convenient for the user to use.

For achieving the above object, Soft Circuit Board Union provided by the utility model comprises: an insulating body, have the substrate of a horizontal expansion, and substrate bottom and both sides protrude out base plate and side plate respectively forward, offer some the first terminal grooves in the base plate, offer some second terminal grooves in the substrate; One rotatable cover, insulating body pivots and opens or fasten with insulating body relatively, and bottom, rotatable cover both sides is provided with cam shaft, and some grooves of replacing are offered at middle part, rotatable cover rear end; And plurality of terminals, each terminal includes underarm and upper arm, and correspondence is contained in first and second terminal groove of insulating body the convex contact jaw that stretches out of underarm front end respectively, the upper arm front end forms the support end, and the support end is stretched into replacing of rotatable cover and also replaced rotatable cover in the groove downwards.It is characterized in that: this Soft Circuit Board Union also comprises a pair of inserting column, offer guiding groove in the side plate of described insulating body, inserting column is corresponding to be inserted in this guiding groove, the approximate mid-section of inserting column upwards protrudes out and forms the stopper section, the side plate of stopper section and insulating body surrounds the pivot groove, pivot groove upper end is by the side plate sealing of insulating body, the cam shaft of described rotatable cover is contained in the pivot groove and pivots in it, when rotatable cover and insulating body were opened, the oblique distance of cam shaft was greater than the vertical height of pivot groove.

The beneficial effects of the utility model are: when inserting outside flexible circuit board, even it can touch rotatable cover in insertion process, yet because the oblique distance of cam shaft is greater than the vertical height of pivot groove, if desire to make rotatable cover to overturn downwards, then must apply enough rotation external force, make cam shaft push through the vertical plane of pivot groove by force, and usually flexible circuit board to the touching power of rotatable cover much smaller than described rotation external force, so, the utility model Soft Circuit Board Union can prevent to rotate the upset that is placed on before using, thereby makes things convenient for the user to use.
