As preferably, described a plurality of contact pin are the two rows that are arranged in order into yi word pattern from left to right with a plurality of breach of stepping down.

As preferably, described a plurality of reference columns are in respectively the both sides of winding displacement groove.

As preferably, described winding displacement groove also is provided with the switch breach of stepping down, and described lancing device is provided with and switch assembling switch corresponding to breach of stepping down.

Adopted the Flat cable connection structure of technique scheme, this Flat cable connection structure comprises the support shell, lancing device and winding displacement, the support shell is provided with a plurality of reference columns and the winding displacement groove corresponding with the winding displacement width, lancing device is fitted in winding displacement groove top by the location hole correspondence, winding displacement is between lancing device and the winding displacement groove, namely winding displacement need only be placed on the winding displacement groove, by reference column and location hole location, again lancing device is pressed on the winding displacement, puncture and fixing winding displacement, this syndeton is novel and rationally, need not weld, the installation winding displacement is very convenient, so that the production efficient of electronic component assembling is high.This Flat cable connection structure is applied in the IC-card slot and produces, and improves at least 500% than traditional welding procedure efficient.Contact pin contact jaw on the above-mentioned lancing device is the oblique breach of fining away in both sides, the contact pin contact jaw punctures winding displacement, oblique breach on the contact pin contact jaw snaps in the winding displacement and the wire in the winding displacement is connected, this connected mode is passed through the physical property architecture advances, need not weld just to reach good contact effect.In a word, the advantage of this Flat cable connection structure is: the winding displacement that can be applied in all kinds of electronic devices and components assemblings connects, and novelty rational in infrastructure connects fast, need not weld, and joint efficiency is high and effective.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

As Fig. 1, Fig. 2 and shown in Figure 3 be Flat cable connection structure on the IC-card socket, comprise support shell 1, lancing device 2 and winding displacement 3, support shell 1 wherein is exactly the housing parts of IC-card slot, all the other syndetons have versatility, and the winding displacement that need only conversion support shell 1 just this Flat cable connection structure can be applied in all kinds of electronic devices and components assemblings connects.Above-mentioned support shell 1 is provided with a plurality of reference columns 12 and the winding displacement groove 11 corresponding with the winding displacement width, and winding displacement groove 11 is provided with a plurality of contact breach 11a and switch breach 11b that step down that step down that puncture.A plurality of contact breach 11a that step down that puncture are in respectively winding displacement groove 11 upper and lowers and are arranged in two rows of yi word pattern, and two rows puncture contact step down breach 11a direction and winding displacement groove 11 perpendicular directions.Two rows puncture the contact breach 11a that steps down and repeat to connect when puncturing, and are connected firmly, and reduce again simultaneously the probability that loose contact occurs, good connecting effect.Above-mentioned reference column 12 is in respectively the both sides of winding displacement groove 11, and the orientation of reference column 12 is consistent with winding displacement groove 11 directions.

Lancing device 2 is provided with a plurality of contact pin 23, a plurality of contact 22 and a plurality of location hole 21; contact 22 is the elastic metallic contacts that are distributed in lancing device 2 tops and protrude end face; contact pin 23 is the bending shape sheet metals that are in below, lancing device 2 bottom surfaces; contact pin 23 is connected with contact 22; be that the elastic metallic contact of above-mentioned protrusion end face extends to below, lancing device 2 bottom surfaces and bending just forms this contact pin 23; in fact, to be sheet metals of being connected as a single entity consist of through bending and pressing mold arcwall face contact pin 23 and contact 22.Therefore, the upper end of contact pin 23 and above-mentioned elastic metallic contact are connected as a single entity, and the lower end of contact pin 23 is contact jaws.The contact jaw of contact pin 23 is the oblique breach 23b that fine away in both sides, and namely contact jaw is by the bur 23a of two sharpenings of bilateral symmetry, and the inboard inclination of bur 23a consists of oblique breach 23b.A plurality of contact pin 23 are in respectively lancing device, and about in the of 2 both sides, with contact 22 quantity Matching and link to each other and corresponding with a plurality of breach 11a quantity Matching and positions of stepping down.A plurality of location holes 21 and a plurality of reference column 12 quantity Matching and position are corresponding.Lancing device 2 is fitted in winding displacement groove 11 tops by location hole 21 correspondences, winding displacement is between lancing device 2 and the winding displacement groove 11, contact pin 23 contact jaws puncture winding displacement 3, and the oblique breach 23b that contact pin connects on 23 contraventions snaps in the winding displacement 3 and the connection of the wire in the winding displacement 3.

The above-mentioned contact point pin 23 that punctures has very sharp oblique breach 23b, upper large middle little, this structure very easily punctures lead-in wire, realize being communicated with winding displacement 3 inner copper wires, adopt the structure of lancing device 2, be conducive to solve the low problem of production efficiency that traditional welding technique has, good connecting effect has also promoted product quality simultaneously.

When puncturing contact point pin 23 and puncture winding displacement 3, puncturing contact point pin 23 will introduce the wire in the winding displacement 3 among the oblique breach 23b, in order to prevent the loose contact of wire and contact pin 23, tiltedly the middle place of breach 23b also designs a narrow and small slit, such structure is so that the winding displacement contact stabilization, and the contact effect is very good.
