[embodiment]

Below in conjunction with accompanying drawing the utility model electric connector is made and to further describe.

Referring to figs. 1 through Fig. 7, the utility model electric connector, be used for electrically connecting the chip module (figure does not draw) and circuit board (not drawing among the figure) that are provided with some stitch, comprise pedestal 1, loam cake 2 and drive unit 3, wherein drive unit 3 comprises operating body 31 and push body 32.

Pedestal 1 comprises main part 11, which is provided with some accepting grooves 12, to accommodate conducting terminal (not drawing among the figure) respectively; Pedestal 1 one ends are provided with pivot connected slot 13, run through the both sides of pedestal 1, are provided with depressed part 14 in the peripheral region, pivot connected slot 13 about middle part of upper surface, and depressed part runs through pivot connected slot 13; Pedestal 1 other end upper surface 15 is roughly step-like, and from then on end stretches out and is provided with boss 16, which is provided with a protruding grain 17.

The main part 11 corresponding flat parts 21 that are provided with of loam cake 2 and pedestal 1, corresponding pedestal 1 accepting groove 12 is provided with some through holes 22 on it, inserts for the stitch of chip module; Loam cake 2 lower surfaces one end is provided with two projections 24, form first conduit 23 between the projection 24, and first conduit 23 is corresponding with the pivot connected slot 13 of pedestal 1; The other end of loam cake 2 is provided with second conduit 25 (also can establish a stop section).

Operating body 31, roughly be frame structure, one end of framework is provided with first articulated section 311, its adjacent dual-side is first connecting portion 314, one side relative with first articulated section 311 is provided with fixed part 313, which is provided with fixing hole 316, and this fixed part 313 outwards convexes with pulling part 317, wherein first articulated section, 311 about medium positions are provided with protuberance 312 inwardly, wherein are provided with two pivoted holes 315 relatively near first articulated section 311 on two first connecting portions.

Push body 32, roughly be " ㄇ " shape, second connecting portion 322 that it comprises pushing

part

321 and 321 two ends vertical extent form from the pushing part, wherein pushing part 321 is articulated in second conduit 25 of loam cake 1, vertically stretch out from the free terminal of two second connecting portions 322 and to be provided with pivot 323, can insert in the pivoted hole 315 of first connecting portion 314 of operating body 31, be articulated together.

When the assembling electric connector, at first the pivot on the push body 32 323 is inserted in the pivoted hole 315 of first connecting portion 314 on the operating body 31, first articulated section 311 of operating body 31 places in the pivot connected slot 13 of pedestal 1, and the pushing part 321 of push body 32 places 15 places of getting out of a predicament or an embarrassing situation, the end of pedestal 1, and second connecting portion 322 is positioned at the both sides of pedestal 1; Cover loam cake 2, make first conduit 23 of loam cake 2 accommodate first articulated section 311 of operating body 31, the through hole 22 of loam cake 2 is corresponding one by one mutually with the accepting groove 12 of pedestal 1, second conduit 25 of loam cake 2 is accommodated the pushing part 32 (if on to cover what establish be the stop section, then the stop section must be placed this outside, pushing part) of corresponding push body 32.

After chip module is installed, pull operating body 31 downwards, first articulated section 311 of operating body 31 rotates, and its protuberance 312 contacts with the projection 24 of loam cake 2 gradually, and it is produced pressure, and loam cake 2 is moved to an end that is provided with pivot connected slot 13 away from pedestal 1; Simultaneously, the pushing part of push body 32 321 pairs of loam cakes, 2 second conduits, 25 outer rims produce pressure, and first thrust direction that 31 pairs of loam cakes of second thrust direction and operating body 2 produce is identical, be equivalent to flat part 21 is produced a pulling force, like this, can prevent or reduce the loam cake warpage that makes progress, simultaneously, make when pressing down operating body, more laborsaving, convenient; When operating body reaches the fixed position, the displacement that the relative pedestal of loam cake produces equals the height of protuberance 312 of the articulated section 311 of operating body 31, fixed part 313 on the operating body 31 and the boss 16 on the pedestal 1 match, protruding grain on the boss 16 buckles in the fixing hole 316 of fixed part 313, thereby reaches the effect that chip module stitch and electric connector conducting terminal better are connected.

Certainly, also can on the fixed part of operating body buckling parts be set, an end of corresponding pedestal is provided with groove, and it is snapped together, and reaches the effect that chip module and electric connector are connected and fixed.

By implementing the utility model technological means, can prevent the loam cake warpage that makes progress, guarantee that the stitch of chip module better is connected with the electric connector conducting terminal, simultaneously, make when pressing down operating body, more laborsaving, make things convenient for.
