Utility model content

The purpose of this utility model is to provide a kind of FFC plate terminal adapter, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the utility model provides following technical scheme:

A kind of FFC plate terminal adapter, comprise plastic cement main body, plastic lid, contact terminal and earth terminal, described contact terminal and earth terminal are arranged in plastic cement main body respectively, and described plastic lid is movably arranged in the plastic cement main body above contact terminal; Be provided with iron-clad grounding elastic part above described earth terminal, iron-clad grounding elastic part lengthened and optimizes to increase its elasticity, be arranged between plastic lid with iron-clad grounding elastic part extrude and contact; Connector is provided with socket end, is provided with the identification guide plate of compatible FFC winding displacement at socket end place; Hollow-core construction is arranged to avoid being short-circuited between pcb board and iron-clad bottom iron-clad in plastic cement main body; The contact area of contact terminal is flattened, with effective contact area of the golden finger and contact terminal that increase FFC winding displacement.

As further program of the utility model: described socket end and contact terminal are positioned at the both sides of earth terminal.

Compared with prior art, the beneficial effects of the utility model are: the utility model is rational in infrastructure, solve the shortcoming that existing FFC connects machine existence, have ground connection excellent, insert smoothly, fail safe high, for the input of liquid crystal module display, effective transmission of signal guaranteed by safety and stable structure.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1, in the utility model embodiment, a kind of FFC plate terminal adapter, comprise plastic cement main body 1, plastic lid 2, contact terminal 3 and earth terminal 4, contact terminal 3 and earth terminal 4 are arranged in plastic cement main body 1 respectively, and plastic lid 2 is movably arranged in the plastic cement main body 1 above contact terminal 4.

As shown in Figure 2, iron-clad grounding elastic part 5 is provided with above earth terminal 4, iron-clad grounding elastic part 5 is lengthened and optimizes structure to increase its elasticity, be arranged between plastic lid 2 with iron-clad grounding elastic part 5 extrude contact, improving the anti-tired deformation of iron-clad grounding elastic part 5 self simultaneously, with plastic lid 2 extruding iron-clad grounding elastic part 5 downwards, ensure contact, even if iron-clad grounding elastic part 5 is out of shape, also effectively can prevent the phenomenon of loose contact, thus improve the undesirable problem of ground connection.And the iron-clad grounding elastic part head of traditional FFC plate terminal adapter is in vacant state, as shown in Figure 3, if connector is in swapping process, because misoperation causes iron-clad grounding elastic part to be out of shape, easily there is the problem of loose contact, cause earthing failure.

As shown in Figure 4, connector is provided with socket end, and socket end and contact terminal 3 are positioned at the both sides of earth terminal 4, is provided with the identification guide plate 8 of compatible FFC winding displacement at socket end place.And traditional FFC plate terminal adapter is when practical application, do not fix with the relative position direction of operating personnel, as shown in Figure 5, therefore when operating personnel can not look at the socket of connector straight, FFC winding displacement is inserted in connector, difficulty can be become, and easily cause misoperation, damage FFC winding displacement or connector.

As shown in Figure 6, being arranged to hollow-core construction bottom the iron-clad in plastic cement main body, when connector is welded on pcb board, is plastic cement bottom connector, because plastic cement is insulator, thus the risk that the iron-clad avoiding PCB mainboard and connector is short-circuited.As shown in Figure 7, because FFC plate terminal adapter adopts iron-clad as earthing conductor, also covered by iron-clad bottom traditional FFC plate terminal adapter, if pcb board just in time also has wiring at connector bottom section, so connector in the course of the work, bottom iron-clad easily punctures the insulating varnish of pcb board, causes short circuit.

As shown in Figure 8, the contact area of contact terminal is flattened, with effective contact area of the golden finger and contact terminal that increase FFC winding displacement, reduce the risk of poor flow.As shown in Figure 9, when traditional FFC winding displacement inserts connector, due to tolerance fit reason, there is the risk of poor flow.

To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.

In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technical scheme in each embodiment also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
