Abstract

An apparatus of electric connection installed on the circuit board comprises a socket and a tightening-up device, wherein, a conductive region with a plurality of via holes on both sides are restricted on the circuit board. The tightening-up device comprises a frame, a lid connected with the frame that can be lifted up or down and an adapting piece for fixing the lid on the frame. The frame is arranged surround the apparatus of electric connection from the top down and equipped with a plurality of convex columns which is weld through the via holes on the circuit board. The socket and the tightening-up device can be assembled on the circuit board separately utilizing the convex columns. Thereby the hot deformation of the socket caused by prior method that the socket and the tightening-up device weld on the circuit board simultaneously is avoided.

Embodiment

About aforementioned and other technology contents, characteristics and effect of the present utility model, in the detailed description of a following cooperation preferred embodiment with reference to the accompanying drawings, can clearly present.

Consult Fig. 3 and Fig. 4, first preferred embodiment of the utility model electric connector can be installed on the circuit board 8, circuit board 8 is limited with conduction region 82, the two opposite sides of conduction region 82 are respectively equipped with a plurality of through holes 81, and in order to be electrically connected chip module 7 (for example CPU) and circuit board 8, electric connector 1 comprises socket connector 2 and withholds device 3.Withhold device 3 and make, comprise framework 31, lid 32 and locating part 33 by metal material.Framework 31 from top to bottom frame places socket connector 2 all sides, and the perisporium 312 that has hollow diapire 311, up extended by diapire 311 outer peripheral edges, and a plurality of projection 313 that is down extended and be arranged in the described through hole 81 of circuit board 8 by diapire 311 inner peripherals.Lid 32 can lift and be hubbed at perisporium 312 with closing, and has two pivot parts 321, the limiting section 322 between two pivot parts 321, and the pressing portion 323 that is positioned at described pivot part 321 opposition sides.Locating part 33 is for the bending body of rod and be hubbed at perisporium 312, have pivot joint section 331 that two and perisporium 312 articulate, be connected in two sections of pushing 332 that articulate between the section 331 and arch upward toward central authorities, and by the section of pulling 333 of the basic at right angles bending of the free end that articulates section 331 extension.The overbending direction of the section of pulling 333 is identical with the direction that arches upward of the section of pushing 332, make the section of pulling 333 at stowed position when (as shown in Figure 4), the section of pushing 332 can press on the pressing portion 323 of lid 32 and lid 32 is fixed, simultaneously lid 32 applies pressure to chip module 7, it is electrically connected in the crimping mode with socket connector 2, and the perisporium 312 of framework 31 is formed with trip 314, makes the section of pulling 333 be fastened on trip 314 separatably.Will the section of pulling 333 break away from up to pull to removing position (as shown in Figure 3) behind the trips 314 and can discharge lid 32 so that chip module 7 is taken out or inserts, in addition, the limiting section 322 of lid 32 be in order to avoid excessively rotation and break away from framework 31 of lid 32.Though the locating part 33 of present embodiment is the body of rod, also can be screw or slide block etc., modes such as available spiral locking or fastening are fixing with framework 31 with lid 32, and therefore, lid 32 does not exceed with present embodiment with the fixed form of framework 31.

Consult Fig. 3, when electric connector 1 is assembled with circuit board 8, earlier socket connector 2 and circuit board 8 are utilized the higher reflow stove welding of process temperatures fixing, to reach the preferable effect that connects.Consult Fig. 5 and Fig. 6, then will withhold device 3 (framework 31, lid 32 and locating part 33 have been combined in advance) frame places on the socket connector 2, and make described projection 313 be arranged in corresponding described through hole 81, utilize the lower tin stove of process temperatures that described projection 313 is welded on the circuit board 8 again, make and withhold device 3 and be fixed in circuit board 8 (referring to Fig. 4).Because the process temperatures when welding with the tin stove is lower, the heat energy of withholding device 3 absorptions is less, can not cause the plastic material distortion in the socket connector 2.

Generally speaking, electric connector 1 of the present utility model can make socket connector 2 and withhold device 3 and utilize 8 welding of different welding processing procedures and circuit board fixing respectively, can effectively avoid in existing processing procedure, withhold device 3 and absorb a large amount of heat energy of storage because enter high temperature reflow stove with socket connector 2, and after leaving the reflow stove, discharge stored heat energy, and cause the distortion of socket connector 2, so can realize the purpose of this utility model really.

The above only is preferred embodiment of the present utility model, therefore can not limit the scope that the utility model is implemented with this, promptly, all belong in the scope that the utility model patent covers so long as the simple equivalent of being done according to the utility model claim and utility model description changes and modifies.
