Description

Socket connector

[technical field]

The utility model is about a kind of electric connector, especially a kind of zero-force connector for socket that is used to electrically connect central processing unit (CPU) and printed circuit board (PCB) (PCB).

[background technology]

Zero-force connector for socket is widely used in computer realm, is used for central processing unit is electrically connected to printed circuit board (PCB) (PCB), to realize the exchanging of data and signal between the two.This connector generally comprises a pedestal that is fixed in circuit board surface, one and movably is installed on the lid on the pedestal and drives the drive unit of lid with respect to base motion.This drive unit at first drives lid to the enable possition, and this moment, central processing unit was mounted on the electric connector with zero insertion force, drives lid then and moves to make position, and realize electrically connecting between central processing unit and the circuit board this moment.

Prior art has disclosed the multiple drive unit that is used for this Zero insertion connector, as on August 28th, 1996 disclosed Chinese patent ZL95223360.6 number and on January 30th, 2002 disclosed Chinese patent all disclosed a kind of design that utilizes rotating driving lever to drive lid for ZL01221158.3 number, as shown in Figure 1, this driving lever 60 comprise the operating portion that is arranged at connector 6 one sides and be arranged at pedestal and lid between axial region, when wherein driving lever 60 rotates to vertical position, central processing unit 4 is mounted on the electric connector 6 with zero insertion force, when operating portion rotates to horizontal level, realize between central processing unit 4 and the circuit board (not icon) electrically connecting.This drive unit operates easily, but need on connector 6, installation driving lever 60 be set extra slot milling, increase the volume of whole connector 6 virtually, and the rotary manipulation of this driving lever needs bigger solid space, so this connector 6 is difficult to be applied on the smaller notebook of integral thickness.

Prior art has also disclosed the design of another kind of drive unit, as on May 10th, 2000 disclosed Chinese patent ZL99226538.X number, in No. the 5730615th, the United States Patent (USP) of bulletin on March 24th, 1998, in the electric connector structure that disclosed for No. 6059596 of United States Patent (USP) of bulletin on May 9th, 2000.As Fig. 2, shown in Figure 3, the pedestal 70 of this connector 7 is provided with a groove 700, and corresponding to these groove 700 places groove 720 is arranged on the lid 72, one independently shifting part 5 can be by these groove 720 these grooves 700 of insertion, and drive lids 72 and move with respect to pedestal 70 by rotating this shifting part 5, this design can reduce the volume of whole connector 7 and can save the space, but, direct butt and push the side of lid 72 when shifting part 5 drives lids 72, because lid 72 is to be made by the insulating material such as plastics, so plastic deformation takes place even breaks in lid 72 easily under the extruding of shifting part 5, and because the thickness of lid 72 is generally thinner, shifting part 5 is easy to and can causes damage to the central processing unit 4 that is installed on the lid 72 and to it by butt during operation.

Because the existence of above drawback is necessary to design a kind of new-type socket connector.

[summary of the invention]

The purpose of this utility model is to provide a kind of socket connector with drive unit, and its unitary construction is less relatively, and can guarantee that the safe and effective realization of drive unit drives function.

For achieving the above object, the utility model socket connector comprises pedestal and the lid that is installed on the pedestal, wherein lid can move on unlatching and make position relative to pedestal, have the plurality of rows terminal accommodation holes on the pedestal and accommodate conducting terminal respectively in wherein, one end of pedestal also is provided with groove, groove corresponding to pedestal on the lid is provided with groove, contiguous groove place is convexly equipped with the projection that a metal material is installed, when lid is positioned at the enable possition, groove and groove part stagger, and be installed in central processing unit on the lid this moment.Insert in this groove and the groove driven tool and rotary drive tool, make driven tool be resisted against on the metal coupling and drive lid to move to make position, realize the function that electrically conducts of central processing unit from the enable possition.

Compared with prior art; advantage of the present utility model is to allow metal coupling and the driven tool on the lid connect; rather than allow lid directly contact with driven tool, and so both can finish the driving process, can form protection to lid and central processing unit again.

[embodiment]

See also Fig. 4 and Fig. 5, the utility model socket connector 1 comprises pedestal 10, lid 20 and plurality of conductive terminals 30.Wherein pedestal 10 is all made by insulating material with lid 20, have the terminal accommodation holes 12 suitable on the pedestal 10 to hold these conducting terminals 30 in wherein with conducting terminal 30 quantity, 20 of lids movably are installed on the pedestal 10 and can move on unlatching and make position with respect to pedestal 10, when it is in the enable possition, central processing unit 4 is installed on the lid 20 with zero insertion force, when being in the close position, central processing unit 4 electrically conducts with conducting terminal 30.Outstanding on two sidewalls of pedestal 10 by several rib 13 locating pieces 14, and can match with the corresponding depression breach (not icon) on the lid 20, so that pedestal 10 and lid 20 are linked together.

Please cooperate with reference to figure 6 and Fig. 7, an end of pedestal 10 is not provided with the recessed strip groove 16 that a longitudinal extension is arranged in terminal accommodation holes 12 places, and the part of a sidewall of this groove 16 is processed to skewed inclined-plane 160; One end of lid 20 also offers a groove 22 corresponding to groove 16 places of pedestal 10, the size basically identical of the size of this groove 22 and groove 16, two sidewalls of groove 22 all have part to be processed to inclined plane 220,222, and these two inclined planes 220,222 are parallel substantially.When lid 20 was in the enable possition, groove 22 partly staggered in vertical direction each other with groove 16, and this moment, inclined-plane 160 and inclined-plane 220 were in its incline direction is in a plane.When lid 20 was in the close position, groove 22 aligned in vertical direction substantially with groove 16.

Contiguous groove 22 places are convexly equipped with a projection 24 are installed on lid 20 upper surfaces, this projection 24 is to be made by the metal material that is different from lid 20, it includes the retainer portion 242 that edge is embedded in the body portion 240 in the lid 20 and protrudes in lid 20, and the thickness of the height of this retainer portion 242 and central processing unit 4 is suitable substantially.

Refer again to Fig. 6 and Fig. 8, lid 20 shown in Figure 7 is in the enable possition with pedestal 10, this moment an auxiliary driven tool, be that a poke rod 5 inserts in this groove 22 and the groove 16 at a slant along the inclined surface 220,160 of groove 22 with groove 16 shown in the figure, and to terminating on the inclined plane 222; Lid 20 shown in Figure 8 is in the close position with pedestal 10, and this moment, poke rod 5 rotated to upright position substantially.In this rotary course; poke rod 5 is resisted against that to be driven lid 20 on the projection 24 moving to the make position slippage by the enable possition; the existence of projection 24 simultaneously can prevent that poke rod 5 directly is resisted against on the central processing unit 4, thereby protection central processing unit 4 avoids being damaged.

It is pointed out that the groove on the lid 20 22 is optional in the utility model, also can construct and realize its function by other.Fig. 9 is the diagram of another execution mode of the utility model, wherein pedestal 10 ' is provided with groove 16 ', and lid 20 ' outer peripheral edges do not exceed this groove 16 ' and groove 16 ' are exposed, to allow process auxiliary drive instrument 5 can insert in the groove 16 ' and to drive lid 20 ' relative pedestal 10 ' motion, this design equally can realize the purpose of this utility model.
