Specific embodiment

As shown in Fig. 1 to 7, this utility model provides the component of a kind of automotive wire bundle terminal and interface arrangment, automotive wire bundle (not shown) is located inside terminal 1, and the terminal 1 is located in interface arrangment 2, wherein, the terminal 1 includes：It is square Closing head 3 and U-shaped afterbody 4,3 both side surfaces of the head have the boss 5 for extending, the upper following table of the head 3 There is on the outside of face square hole 6, the inner side of the upper surface has the projection 7 that cross section is circular arc, and the inner side of the lower surface has Elastic cantilever 8；The interface arrangment 2 includes datum hole 9, and the datum hole 9 has：The groove 10 coordinated with the boss 5, with institute State the shell fragment 11 that upper surface and the lower surface coordinate, and the free end of the shell fragment 11 has and is contained in the square hole 6 Projection 12.

In this utility model, wire harness is fixed by raised 7 and elastic cantilever 8 on the inside of the head 3 of terminal 1, The outside of head 3 passes through boss 5 and the datum hole of square hole 6 and interface arrangment 2 coordinates the external stability for realizing terminal 1 simultaneously, improves The reliability that is connected of inside and outside.

In this utility model, terminal 1 designs the groove 10 of two boss 12 (preferably rectangular) link structure of limited location It is interior, play and guiding, spacing, fixed effect are installed.

The design of the projection 7 of circular arc can obtain bigger thrust, and compression property more preferably, is not susceptible to loose contact.
