Description

Soft Circuit Board Union

Technical field

A kind of Soft Circuit Board Union refers to that especially a kind of insulation colloid is provided with fastener, to support actuator and to grab the Soft Circuit Board Union that engages with the actuator hook.

Technical background

Most of flexible circuit board (FPC, Flexible Printed Circuit) employed connector, usually by an actuator, one insulation colloid and a plurality of contact terminal of being located in the insulation colloid are formed, this actuator and this contact terminal are usually designed to bearing and axostylus axostyle each other, make actuator to rotate by the formed fulcrum in both contact positions, the colloid that insulate simultaneously is provided with insertion groove, flexible circuit board is inserted this insertion groove, by actuator flexible circuit board is gripped simultaneously, circuit junction on the flexible circuit board can be contacted with contact terminal, reach the effect of electric connection.

The structure of similar above-mentioned Soft Circuit Board Union and improvement thereof, revealed in considerable technological document, as No. the 91208035th, the novel patent application of TaiWan, China, Japan patent of invention Te Kaipingdi 9-82427 number, ask in the TaiWan, China patent of invention No. 89116345 etc., all are patents about above-mentioned Soft Circuit Board Union, wherein:

Japan patent of invention Te Kaipingdi is for 9-82427 number the connector that is used for flexible circuit board about a kind of, its actuator is provided with a protruding axle at two ends, can be placed in the recess of insulation colloid upper end, make actuator when contact terminal rotates, can be supported by insulation colloid two side, the actuator both sides are provided with salient point simultaneously, when actuator cuts out, this salient point can snap into the draw-in groove of insulation inboard, colloid two side, makes actuator can not unclamp because of the flexible circuit board pulling.

The TaiWan, China application for a patent for invention then is the connector that another kind is used for flexible circuit board No. 89116345, the actuator of this connector is provided with a lock part and an operation part, the insulation colloid then is provided with one and accepts part, be engaged in by the lock part and accept part, make actuator flexible circuit board can be gripped, with the operation part pulling, then actuator can be opened.

In the above-mentioned patent, when connector is seized fixedly flexible circuit board on both sides by the arms, all be to grab the mode that engages with insulation colloid hook by actuator, make actuator can be fixed in closed condition, the reason flexible circuit board does not spur and opens, but because the insulation colloid is usually by resin, rubber or synthetic plastic are made, therefore interfere retain strength relatively poor, also be easier to simultaneously produce distortion because of using for a long time, make fixed effect produce unsettled situation, in addition, also because the material characteristic of insulation colloid is easy because design temperature on making, pressure, the factor that demould time etc. are extra, cause insulation colloid deviation and below standard standard to some extent on Form Factor, and then influenced actuator and grab the intensity that engages with the accuracy and the hook of the contraposition between the colloid of insulating.

The novel patent application of TaiWan, China then is for No. 91208035 to disclose the another kind of technology that fastens by actuator and insulation colloid, the connector of this patent vertically respectively has location notch on insulation both sides, colloid the place ahead, actuator (being referred to as with cover plate in this patent specification) both sides, the place ahead vertical plane inner edge has locating piece, by this, when locating piece snaps into location notch, make actuator can positioning and fixing in the insulation colloid, in addition, this patent has one simultaneously and is inserted in back to front in the fastener of insulation colloid location division, this fastener one side has a hook portion, side direction elastic force can be provided, after making the protruding axle of actuator both sides be placed in the location division along the hook portion of compression, hook portion is the effect that reinstatement forms the location.

Though above-mentioned patent is located at location notch and locating piece on the place ahead vertical plane of insulation colloid, but still be to grab with the actuator hook with the insulation colloid to engage, therefore still have because of making shortcoming bad or that service failure causes actuator closely to fix, and the fastener of both sides only has the convenience that elasticity is installed actuator, there is no other effect.

The utility model promptly is to research and develop the resulting utility model of design at above-mentioned shortcoming, after utility model content and execution mode will be specified in.

The utility model content

Main purpose of the present utility model is to provide a kind of Soft Circuit Board Union, and the strength that its increase engages when closing actuator makes flexible circuit board can be in a good stationary state and stable electric connection state.

Another purpose of the present utility model is to provide a kind of Soft Circuit Board Union, and the bearing intensity that it improves the protruding axle in actuator both sides makes actuator after use repeatedly, still can keep accurate position.

A purpose more of the present utility model is to provide a kind of Soft Circuit Board Union, the bond strength that it increases insulation colloid and substrate, make connector can be because of not pullling of flexible circuit board loses stability.

Above-mentioned purpose and effect are to realize by following technology and structure:

The utility model Soft Circuit Board Union, comprise an insulation colloid, an actuator, at least two fasteners and a plurality of terminal, this insulation colloid is provided with a plurality of spaced flutings, in order to ccontaining this terminal, the left and right sides is provided with accommodation space in order to ccontaining this fastener, this accommodation space forms opening in this insulator top, makes fastener can be arranged at the accommodation space of this insulation colloid left and right sides from top to bottom; This actuator left and right sides wall is provided with projection and protruding axle.

Wherein, this fastener is provided with catch in this actuator projection place relatively, makes the actuator projection can be fastened on this catch; The protruding axle of this actuator place then is provided with a recess relatively, support as the protruding axle rotation of this actuator, after flexible circuit board inserts between actuator and the insulation colloid, actuator is fixed to this catch place up to the actuator projection along the formed axle center rotation of both sides recess, actuator cuts out, reach fixedly flexible circuit board and make flexible circuit board and this termination contact forms and electrically connects.

In addition, design runs through this insulation colloid with accommodation space, and formation is cracked bottom this insulation colloid, and this fastener bottom is provided with at least one transverse concave groove, making this at least one transverse concave groove be exposed to this cracks, this transverse concave groove can increase the welding contact area, makes this connector when being fixedly welded on substrate, can strengthen the welding strength of fixation.

Because this connector is when cutting out actuator, its engaging strength depends on the relative position of actuator projection and fastener catch, adjust by the position or the length of catch easily, assembling has motor-driven characteristic easily, and fastener can use sheet metal manufacturing, has hard high-strength, reduce because of the concentrated deformed damaged that is caused of the permanent stress that uses or engage strength and reduce, it is same because fastener is to make with sheet metal, the protruding axle at actuator two ends can have more supportive in rotation, add the upper fastener bottom and be provided with at least one transverse concave groove, make the weld strength of connector and substrate to increase, therefore can significantly reduce the situation that loose contact is arranged because of pullling of flexible circuit board.

For making audit crew can understand the spirit and the technical characterictic of the utility model more, after being specified in for embodiment now.
