The relevant a kind of zero-force connector for socket of the utility model, especially a kind of zero-force connector for socket that prevents the conducting terminal distortion.

Along with development of computer, computer has the more and more higher speed of service and more and more stable performance, and in order to be suitable for this trend, computer needs close mating relationship with connector.Relevant prior art please refer to United States Patent (USP) the 5th, 947, and No. 778 cases please refer to shown in Figure 1ly, and existing zero-force connector for socket 5 comprises insulating body 50 and is housed in plurality of conductive terminals 51 in the insulating body 50.Insulating body 50 have upper surface 501 and with upper surface 501 opposing lower surface 502.Insulating body 50 also is provided with and runs through some accepting holes 503 that are used for accommodating corresponding conducting terminal 51 of upper and lower surperficial 501,502.Conducting terminal 51 comprises fixed part 512, by fixed part 512 upwardly extending contact sites 511 and the afterbodys 513 that extend downwards by fixed part 512, wherein fixed part 512 comprises by the outward extending two pairs of projections 514 of lateral margin.

When conducting terminal 51 was installed in the accepting hole 503, the sidewall interference of projection 514 and accepting hole 503 was with conducting terminal 51 stable being retained in the insulating body 50.When conducting terminal 51 and corresponding central processing unit and circuit board butt joint, contact site 511 and afterbody 513 electrically connect with central processing unit and circuit board respectively.But perpendicular to conducting terminal 51 will make conducting terminal 51 produce distortion to relay, thereby influence the electric connection between itself and central processing unit and the circuit board.Therefore, this kind zero-force connector for socket still has further improved necessity.

The purpose of this utility model is to provide a kind of zero-force connector for socket, and its conducting terminal can be stablized and is retained in the insulating body, is connected thereby can carry out excellent electrical property with butt joint central processing unit and circuit board.

The purpose of this utility model is achieved in that a kind of zero-force connector for socket that connects central processing unit and circuit board comprises an insulating body and is housed in plurality of conductive terminals in the above-mentioned insulating body, wherein insulating body some accepting holes of having upper and lower surface and running through upper and lower surface.This accepting hole comprises two relative the first side wall and second sidewalls adjacent with the first side wall.Conducting terminal is housed in the above-mentioned accepting hole, and each conducting terminal has fixed part, reached the afterbody that is extended by fixed part by the upwardly extending contact site of fixed part downwards.Fixed part comprises by the outward extending boss of lateral margin and some projectioies of outwards being protruded by the surface between lateral margin, above-mentioned boss and projection respectively with first, second sidewall interference of accepting hole.

Because the utility model zero-force connector for socket is provided with on the fixed part of conducting terminal respectively and the first side wall of accepting hole and the boss and the projection of the second sidewall interference, so conducting terminal of the present utility model can be stablized in the accepting hole that is retained on insulating body, so its electric conductivity is stable

Below in conjunction with drawings and Examples the utility model is further described.

Please refer to shown in Figure 2ly, the utility model zero-force connector for socket 1 comprises an insulating body 2 and is housed in plurality of conductive terminals 3 in the insulating body 2.

Insulating body 2 has a upper surface 21 and and upper surface 21 opposing lower surface 22 towards corresponding central processing unit (not shown).Insulating body 2 also is provided with and runs through upper and lower surperficial 21,22 accepting holes 23 that are used for accommodating corresponding conducting terminal 3.Above-mentioned accepting hole 23 is provided with two relative the first side walls 24 and second sidewall 25 adjacent with the first side wall 24.

Please refer to shown in Figure 3, conducting terminal 3 has fixed part 32, by fixed part 32 upwardly extending contact sites 31 and the afterbodys 33 that extend downwards by fixed part 32, wherein fixed part 32 comprises by the outward extending boss 34 of both side edges and is located near the above-mentioned boss 34 four semi-cylindrical hills 33.

Please refer to Fig. 4 and shown in Figure 5, when conducting terminal 3 is assembled in the above-mentioned accepting hole 23, boss 34 and projection 35 respectively with the first side wall 24 and 25 interferences of second sidewall, with conducting terminal 3 stable being retained in the insulating body 2.When this zero-force connector for socket 1 docks with related circuit plate and central processing unit, the joint of contact site 31 and central processing unit plug (not shown) and afterbody 33 and circuit board spliced eye (not shown) applies an active force to conducting terminal 3, this active force makes conducting terminal 3 produce distortion, and cooperates the above-mentioned distortion of prevention conducting terminal 3 generations between boss 34 and the first side wall 24 and projection 35 and second sidewall 25, therefore, conducting terminal 3 stable being retained in the insulating body 2.
