[embodiment]

Consult Fig. 1 to shown in Figure 2, the utility model electric connector 100 is used to electrically connect chip module (not shown) to printed circuit board (PCB) (not shown).This electric connector 100 comprises pedestal 7, be mounted on plurality of conductive terminals 9 in the pedestal 7, be mounted on sliding panel 5 on the pedestal 7, be located at top board 4 and snap close piece 3 on the sliding panel 5, be mounted on lid 1, fixed head 6 and the baffle 8 on the pedestal 2 and be mounted on lid 1 and pedestal 7 between elastic component 2, lid 1 pedestal 7 relatively moves up and down.

Pedestal 7 is roughly rectangular, and it comprises main part 71 and autonomous body 71 upwardly extending sidewall 70 all around.Main part 71 is enclosed to form in order to accommodate the host cavity 73 of sliding panel 5 and top board 4 with sidewall 70.Main part 71, sliding panel 5 and fixed head 6 correspondences are provided with the accepting hole (not label) of accommodating conducting terminal 9, and conducting terminal 9 is fixed on the pedestal 7 by fixed head 6.Four corners of main part 71 are provided with location hole 702.Sidewall 70 is provided with some first grooves 703 that cooperate with lid 1 and some second grooves 704 that can cooperate with baffle 8.Four corners of sidewall 70 are provided with accepting hole 701, with the elastic force of assembling elastic component 2 and providing lid 1 to move up and down with respect to pedestal 7.

Sliding panel 5 roughly is plate-like structure, they can be with respect to pedestal 7 horizontal slips, and this sliding panel 5 comprises that roughly rectangular matrix 52, being used to of being provided with in the relative both sides of matrix 52 assemble the holding tank 522 of snap close piece 3 and the trip 53 that extends to form respectively from four corners of matrix 52 downwards.Matrix 52 is provided with the accepting groove 421 that wears for conducting terminal 9.Trip 53 is positioned in the location hole 702 of pedestal 7 so that sliding panel 5 and pedestal 7 are fitted together.

Top board 4 is roughly rectangular, and it is fixed in sliding panel 5 and can slides with respect to pedestal 7 with sliding panel 5.Top board 4 comprises the resettlement section 41 in the middle of being positioned at and is positioned at resettlement section 41 edge part 42 on every side.Described resettlement section 41 is provided with the accommodation hole (not indicating) that passes for conducting terminal 9.Please consult shown in Figure 2ly simultaneously, the upper surface 411 of resettlement section 41 is higher than the upper surface 421 of edge part 42.
