[embodiment]

Below in conjunction with the drawings and specific embodiments, the utility model electric connector is described further.

Please refer to Fig. 1, shown in Figure 2, the utility model electric connector is in order to connect chip module 2, comprise that insulating body 10, conducting terminal (not shown), metal reinforcement 12, metal cap body 13 reach in order to press solidly the rocking bar 14 of metal cap body 13 on metal reinforcement 12, insulating body 10 is arranged in the metal reinforcement 12.

But insulating body 10 is provided with the accepting area 101 of carries chips module 2, and accepting area 101 is provided with plurality of terminals accepting hole (not shown), to accommodate conducting terminal (not shown).

Metal reinforcement 12 is the square frame shape, insulating body 10 is arranged in the metal reinforcement 12, be provided with retaining wall 122 around the metal reinforcement 12, wherein a retaining wall 122 outwards bends and is provided with clamping part 124, in order to hold mutually with rocking bar 14, another adjacent with it retaining wall outwards bending is provided with holding section 125, in order to articulate rocking bar 14, another retaining wall relative with the retaining wall that is provided with holding section 125 is provided with two and articulates axis hole 126, to articulate metal cap body 13.

Rocking bar 14 comprises two articulated sections 141 that are articulated in metal reinforcement 12, is inwardly protruded out a pressing part 142 and extended to form operating portion 143 by an articulated section outside vertical by two articulated sections 141.

Metal cap body 13 is the middle frame shape structure that is provided with through hole, it comprises a square frame shape body 130, body 130 lower surfaces are equiped with the elasticity press body 16 in order to the compacting chip module, totally four of this elasticity press body, and being square is arranged on the body 130, extend internally between the two elasticity press body 16 on the same frame and be provided with protuberance 131, the intensity that is arranged so that reinforcement metal lid 13 of this protuberance 131 is able to further raising, bend extension downwards by body 130 1 ends and be provided with two pivot ends 132, pivot end 132 can be articulated in two of metal reinforcement 12 and articulate in the axis hole 126, make metal cap body 13 be movably connected on an end of metal reinforcement 12, stretch out again after the other end relative with pivot end 132 extends downwards on the body 130 and be provided with button hook 133, when metal cap body 13 closures, stir rocking bar 14 at this moment the pressing part 142 of rocking bar can suppress on button hook 133, at this moment, metal cap body 13 links together with metal reinforcement 12.

When metal cap body 13 and metal reinforcement 12 are in opening, chip module 2 is placed on the accepting area 101, conducting strip (not shown) on the chip module 2 is contacted with conducting terminal (not shown) in the insulating body 10, closed again metal cap body 13, metal cap body 13 is compressed on the chip module 2, stir rocking bar 14 at last and be about to chip module 2 firm being compressed on the electric connector, owing on the lower surface of the body 130 of metal cap body 13, be provided with four elasticity press body 16, directly be arranged at the lower surface of metal cap body because of this elasticity press body 16, its aspect ratio is easier to control, processing is simple, and this elasticity press body 16 is square arrangement on metal cap body, so chip module 2 is more even at metal cap body 13 closed back pressures, so can not influence normally electrically conducting of chip module and circuit board because the chip module discontinuity causes distortion.
