[embodiment]

See also Fig. 1 to Fig. 8, the utility model electric connector comprises insulating body 1 and conducting terminal and is installed in the upper cover body 7 of insulating body 1 one ends in order to compacting chip module 4, the other end at insulating body is equiped with one in order to upper cover body 7 is suppressed the rocking bar 8 on insulating body, be provided with around the insulating body electric connector is connected to syndeton 9 and location structure 6 on the circuit board, and location structure 6 can be welded on the circuit board 5.Wherein conducting terminal comprises first conducting terminal 2 and second conducting terminal 3.

Insulating body 1 is provided with plurality of terminals accommodation hole 10, wherein each accommodation hole 10 is provided with interconnective first conducting terminal 2 and second conducting terminal 3, each accommodation hole 10 is surrounded by first higher retaining wall 11 and the second lower retaining wall 12 respectively, be concaved with location division 111 on first retaining wall 11, this location division can hold and locate first conducting terminal 2, second retaining wall 12 is provided with limiting section 121, this limiting section 121 moves in order to limit the excessive of second conducting terminal 3, and on the terminal inclined-plane 122 that forms of second retaining wall.

The material difference of described first, second conducting terminal 2,3, but be all the metal of sheet, wherein the thickness of first conducting terminal 2 is greater than the thickness of second conducting terminal 3.First conducting terminal 2 is a fine copper, its conductance is higher, one distal process goes out first retaining wall 11 and forms and can (be chip module 4 in the present embodiment with external electronic component, certainly, also can be other electronic component) first junction 20 that electrically connects, forming pressure section 21 near an end of second conducting terminal 3, and pressure section 21 is provided with two down first inclined planes 23, is concaved with groove 24 on the pressure section 21 in addition.This second conducting terminal 3 is an alloyed copper, its elasticity is better, it can (be circuit board (not shown) in the present embodiment with external electronic component that one end forms, certainly, also can be other electronic component) second junction 31 that electrically connects, be overlapped with scolder 5 on second junction 31, the other end relative with second junction 31 forms the two elastic portion 32 that can flexibly support above-mentioned pressure section 21, two elastic portion 32 extends upward a relative stop section 33, these elastic portion 32 ends also comprise two up second inclined planes 34, wherein said first inclined plane 23 can connect with second inclined plane 34, can match with groove 24 in stop section 33, make first, second conducting terminal 2,3 hold fixing by concavo-convex cooperation formation.
