Abstract

The utility model discloses an electric connector which is used for electrically connecting a chip module to a printed circuit board. The utility model comprises a base which is fixedly connected with a circuit board, a cover body which is arranged in the base and can directionally slide along the base, and a drive device which is arranged between the base and the cover body and can drive the cover body to slide, wherein, opposite two side walls are arranged on the base in the direction which is parallel to the sliding direction of the cover body and are provided with a plurality of first buckling and clamping devices; the position of the side wall of the cover body corresponding to the base is provided with a lateral plate which is provided with a plurality of second buckling and clamping devices corresponding to the first buckling and clamping devices. The first and the second clamping and buckling devices are mutually clamped and buckled, which causes the cover body to be not easy to fall off the base and the lateral plate of the cover body is provided with a plurality of bosses staggering the second clamping and buckling devices. The bosses are butted with the side wall of the base; in this way, the match between the cover body and the base is tighter; moreover, because the contact area between the both is reduced, friction noise is decreased in the sliding process of the cover body.

Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector that chip module is electrically connected to printed circuit board (PCB).

[background technology]

Existing electric connection chip module to the socket connector of circuit board mostly is the zero insertion force design, generally comprise in order to electrically connect and reach and the affixed pedestal of circuit board with chip module, movably be installed on pedestal to reach by the lid of zero insertion force state to the effect that well electrically conducts, relevant patent sees also United States Patent (USP) the 5th, 722, No. 848, the 5th, 833, No. 483, the 5th, 947, No. 778, the 6th, 042, No. 413 and the 6th, 231, No. 367 disclose, the correlation technique document sees also Development of ZIF BGA Socket (Connector Specifier, May 2000).But big gap is arranged between the lid of the existing electric connector that these documents disclosed and pedestal, cause the instability that cooperates between pedestal and lid, owing to have the gap between pedestal and lid, make and be offset to both sides in the lid slipping, and then the stitch deflection slippage that can cause docking chip module, the generation not smooth drawback that electrically conducts, and, when the electric connector heating is soldered to circuit board, through the process of heating cooling,, can cause the lid contraction and make the gap reduce owing to have the gap between lid and pedestal, the terminal hole that is provided with on the lid also shrinks and diminishes, and more influences the function of the zero insertion force of electric connector.In addition, even no gap exists between lid and pedestal,, in the lid slipping, easily produce friction noise because lid is that face contacts with the sidewall of pedestal.

[utility model content]

The purpose of this utility model is to provide a kind of electric connector more closely that cooperates that makes between pedestal and lid.

The purpose of this utility model be achieved in that the utility model electric connector comprise the pedestal that is fixed in circuit board, be installed in this pedestal and can along the lid of the directed slippage of pedestal and be installed in pedestal and lid between and can drive the drive unit of lid slippage.Wherein, be parallel to the lid glide direction in pedestal and be provided with relative two side, which is provided with a plurality of first bayonet units, and be provided with side plate corresponding to the sidewall locations of pedestal in lid, this side plate is provided with a plurality of second bayonet units that correspond to first bayonet unit, the mutual buckle of these first, second bayonet units makes that lid is difficult for coming off from pedestal, and second bayonet unit that staggers on the side plate of lid is provided with a plurality of boss, and these boss are connected on the sidewall of pedestal.

Compared with prior art, the utlity model has following advantage: utilize the boss be located on the lid, can strengthen the degree of interference fit between pedestal and lid, make between pedestal and lid cooperate tightr, and reduce the contact area of pedestal and lid, reduce the noise of lid slippage on pedestal.

[embodiment]

See also Fig. 1 to Fig. 3, the utility model electric connector 1 is in order to accepting chip module (not shown) and it is electrically connected to printed circuit board (PCB) (not shown), it comprises the pedestal 10 that butts up against printed circuit board (PCB), be installed in this pedestal 10 and can along the lid 11 of pedestal 10 directed slippages and be installed in pedestal 10 with lid 11 between also can drive the drive unit 13 of lid 11 slippages.

Pedestal 10 is provided with the interface 101 that docks with lid 11, this interface 101 is provided with a plurality of terminal holes 1010 that are arranged, be installed with a conducting terminal 12 in each terminal hole 1010, be provided with a pair ofly perpendicular to interface 101 and the sidewall 102 that is parallel to each other along pedestal 10 thickness directions, the appropriate location is provided with spaced a plurality of first bayonet unit 1021 on sidewall 102.

Lid 11 is provided with the side plate 111 corresponding to the sidewall 102 of pedestal 10, be provided with perpendicular to this side plate 111 and dock with the interface 101 of pedestal 10 and the loading end 112 of carries chips module (not shown), which is provided with and a plurality ofly be matrix distribution and corresponding to the through hole 1121 of the terminal hole 1010 of pedestal 10, wherein first bayonet unit 1021 that is provided with on the sidewall 102 of corresponding pedestal 10 on the side plate 111 is provided with second bayonet unit 1111, first bayonet unit 1021 and second bayonet unit, 1111 mutual buckles make lid 11 be difficult for coming off from pedestal 10 whereby.

On the side plate 111 of lid 11 and with second bayonet unit 1111, keep at a certain distance away and be provided with a plurality of boss 1112, these boss 1112 are connected on the sidewall of pedestal 10, utilize these boss 1112 to make that pedestal 10 and cooperating of lid 11 are more tight and prevent to be offset in lid 11 slippings, and, because boss 1112 is arranged so that the contact area of 11 of pedestal 10 and lids and reduces, can avoid producing noise in lid 11 slippings.

See also Fig. 4, this figure has disclosed second execution mode of the present utility model, the pedestal 10 that this electric connector 1 ' comprise butts up against printed circuit board (PCB) ', be installed in this pedestal 10 ' and can along the lid 11 of pedestal 10 ' directed slippage ' and be installed in pedestal 10 ' with the drive unit 13 of lid 11 ' also can drive lid 11 ' slippage ', wherein pedestal 10 ' be provided with sidewall 102 ', lid 11 ' be provided with side plate 111 ', in pedestal 10 ' a plurality of boss 1112 of sidewall 102 ' be provided with ', boss 1112 ' be connected to lid 11 ' side plate 111 ' on.All the other structures and the effect of reaching are described consistent with first execution mode, at this repeated description no longer.
