It below is terminal structure one preferred embodiment of the present utility model.
Fig. 1 and Fig. 2 are the schematic perspective view of terminal structure of the present utility model in a preferred embodiment, as depicted in figs. 1 and 2, terminal 1 of the present utility model is by integrally formed the making of metallic plate processing, and its structure is divided into wire rod fixed part 10, connecting portion 20 and between aforementioned the two transition region 30.
As depicted in figs. 1 and 2, flexible flat cable 4 one ends with flat structure can be connected on the wire rod fixed part 10, the common formation one of terminal 1 and flexible flat cable 4 one ends be connected use joint; Connecting portion 20 possesses itself can plug function, can form the electric connection state with a subtend jockey arbitrarily; Transition region 30 front and back have different in width, and wire rod fixed part 10 one sides less by width are amplified to connecting portion 20 1 sides gradually.
Wire rod fixed part 10 comprises a base portion 11, a plurality of conduction button arm 12 and a plurality of clip arm 13.Base portion 11 comprises a leading edge 111, two lateral margins 112 and end face 113, and end face 113 is plane structure, is conducive to the flexible flat cable 4 of flat stably is placed on the end face 113, as shown in Figure 3; A plurality of conduction button arms 12 are that one group kenel is respectively formed on two lateral margins 112 with two, after each conduction button arm 12 is extended upward by lateral margin 112, extend to invagination and to the end face 113 of base portion 11 again, make the segment distance of between the cusp 121 on conduction button arm 12 ends and end face 113, being separated by, as shown in Figure 4, and be can be relative mutually between one group the conduction button arm 12 with two, or slightly be dislocation mutually; In present embodiment, be provided with a pair of clip arm 13 in addition, this is arranged at the position of contiguous leading edge 111 with relative kenel to clip arm 13, by two lateral margins 112 extend upward respectively, inside reflexed and extend towards the end face 113 of base portion 11 again, and and end face 113 between the segment distance of being separated by.
Connecting portion 20 is positioned at the other end of terminal 1, and its kenel does not limit, and the structure of looking closely the subtend jockey that is mated decides, and only is an example shown in this preferred embodiment.Connecting portion 20 comprises a base 21 and is positioned at the baffle plate 22 of base 21 both sides to have a shell fragment 23 of giving prominence on the base 21 up, and thus, the subtend jockey can be by flexible fastening between baffle plate 22 and shell fragment 23.Transition region 30 which is provided with a stopper section 31 for adjusting the formed zone of change width between wire rod fixed part 10 and the connecting portion 20, is used for limiting the placed-depth of flexible flat cable 2.
Flexible flat cable 4 has the flat structure, and it is made of insulating barrier 42 coating conductors 41, is provided with the conductor 41 that exposes and the stiffening plate 43 that installs additional in flexible flat cable 4 one ends, and stiffening plate 43 is for increasing the intensity of flexible flat cable 4 one ends; Flexible flat cable 4 only has plain conductor 41, but also can be a spot of many strip conductors 41.
As shown in Figure 4, before flexible flat cable 4 is assembled in wire rod fixed part 10, keeps certain distance between conduction button arm 12 and clip arm 13 and the end face 113, and constitute an opening 114 jointly by clip arm 13 and 113 of end faces, insert for flexible flat cable 4.As shown in Figure 5, when flexible flat cable 4 is presented to certain distance, its leading edge contacts stopper section 31 and forms the location, the button arm 12 of processing conduction then and clip arm 13 make its compacting flexible flat cable 4 downwards, wherein the cusp 121 on conduction button arm 12 ends directly thrusts the conductor 41 on the flexible flat cable 4, make terminal 1 and flexible flat cable 4 form conduction state, 13 on clip arm is to avoid conductor 41 to be compressed on the insulating barrier 42.Because no matter flexible flat cable 4 itself has or not and installs stiffening plate 43 additional and be all the flat structure, so it can be smooth on the end face 113 of base portion 11, as shown in Figure 6 and Figure 7.
In the present embodiment, total a pair of clip arm 13 is arranged on the position of contiguous leading edge 111, and four conduction button arms 12; In fact, as long as bottom line has a conduction button arm 12 to contact with the conductor 41 of flexible flat cable 4, if adjust at the quantity of clip arm 13 and conduction button arm 12, should belong to the category of this patent.
In addition, as shown in Figure 3, a plurality of protuberances 115 can be set more on end face 113, these protuberances 115 are arranged along the length direction of base portion 11, can increase the chucking power to flexible flat cable 4, avoid flexible flat cable 4 to be pulled out easily.In the design, the quantity of protuberance 115, position and shape can cooperate the position of conduction button arm 12 to adjust, and for example the position that may be anchored to when the cusp 121 of button arm 12 presses down should be avoided conducting electricity in the position of protuberance 115; Protuberance 114 can certainly be set, be the whole plane state and keep end face 113.And in Fig. 3, draw out bigger protuberance 115 so that know expression, wherein, protuberance 115 actual sizes should be principle not hinder flexible flat cable 4 to put.
In sum, terminal structure of the present utility model can be connected in conjunction with formation one with a flexible flat cable 4 with flat structure easily and use joint by changing 10 designs of wire rod fixed part, and clamping flexible flat cable 4 that can be stable.
Above-described embodiment just lists expressivity principle of the present utility model and effect is described, but not is used for restriction the utility model.Any personnel that are familiar with this technology all can make amendment to above-described embodiment under spirit of the present utility model and scope.Therefore, rights protection scope of the present utility model should be listed as claims.
