Embodiment

As Fig. 1 to shown in the accompanying drawing 7, the utility model includes protecgulum 1, plastic cement body 2, base 3 and most terminals 4, wherein, protecgulum 1 is the framework that is the rectangle of growing crosswise, its top root edge is provided with the horizontal lug 11 of symmetry, be provided with button hole 111 on lug 11, root edge then is provided with vertical inserting hook 12, and is respectively equipped with fixing hole 13 on the end face of both sides; Plastic body 2 is to be provided with numerical digit and

analogy terminal hole

21,22 in its surface, and the top root edge is provided with the button hole 111 of protecgulum 1 and is corresponding trip 23, and is respectively equipped with the fixing hole 13 of protecgulum 1 in its both sides and is corresponding grooving 24, for installing nut 25; The surface of base 3 is provided with stair-

stepping guide groove

31,32, and is provided with a vertical partition plate 33 between two

guide grooves

31,32, and the bottom then is provided with the open-work 34 that wears for terminal 4.

Combination by aforementioned components, these terminals 4 are set in its front end the

terminal hole

21,22 of plastic body 2, terminal then wear by the open-work 34 of base 3, again the trip 23 of plastic cement body 2 is sticked in the button hole 111 of protecgulum, and be locked on nut 25 after wearing by the fixing hole 13 of protecgulum 1 with a screw 5, make protecgulum 1, plastic cement body 2 and base 3 are fixing, to constitute an electric connector 100, in use, inserting hook 12 is inserted in circuit board, is welded, and can be by the signal of different terminals 4 transmission numerical digits and analogy.
