[execution mode]

For ease of describing enforcement structure of the present utility model in detail, now by reference to the accompanying drawings the utility model is described as follows in detail:

As shown in Figure 1, 2, a kind of power connector 7 comprises: insulating body 1, be fixed in first, second, third conducting terminal 2 in the insulating body, 3,4 and be coated on the metal shell 6 of insulating body outer surface.This embodiment also has a bonnet 5.

This insulating body 1 forms a center column 14 to front end face along the bottom projection, thereby forms annular groove 13.Extend in insulating body 1 rear end face and to be provided with first slot 15 that runs through in the column of center, in the peripheral U-shaped slot 16 that forms of this slot, and in the peripheral ring-type slot 17 that forms of U-shaped slot 16, and form in order plural number on U-shaped slot 16 and the ring-type slot 17 and merges the conduit 161,171 that communicates with insulating body groove 13, be stretched in the groove for terminal

elastic contact part

33,43 wears the inwall 13 of groove 13 and outer wall 12.Form a breach 18 in these insulating body 1 one sidewalls, this breach 18 connects with ring-type slot 17.

The first terminal 2 is provided with tabular fixed part 21, extends to form harpoon shape contact site 23 along fixed part 21 1 ends, and the other end forms welding foot 22.Second terminal 3 is provided with U-shaped fixed part 31, extends to form elastic contact part 33 in a lateral buckling, and opposite side forms welding foot 32.The 3rd terminal 4 is provided with ring-type fixed part 41, and fixed part one lateral buckling extends to form plural elastic contact part 43, and opposite side forms welding foot 44, and this fixed part forms a flat board 45, and forms a shell fragment 44 on dull and stereotyped 45.
