At present, industry generally adopts electric coupler component to remove to electrically connect chip module to circuit board.Introduced a kind of existing electric coupler component as shown in figure 10, it is by forming as the lower part: upper iron shell 100, following iron-clad 200, rocking bar 400 and the inner insulating body 300 that accommodates a plurality of terminals, following iron-clad 200 in the common this electric connector combination is a square box body structure, insulating body 300 is contained in wherein, after insulating body 300 was installed on the circuit board 600 by the terminal in it in the mode of bottom welding, following iron-clad 2 also was locked between insulating body 300 and the circuit board 600.As Figure 11, shown in Figure 12, central processing unit chip 500 is installed on the insulating body 300, and upper iron shell 100 and following iron-clad 200 are fastened.Attaching part on the upper iron shell 100 has a downward active force that the central processing unit chip is fixed.By stress analysis as can be known, the upper iron shell attaching part is subjected to reaction force upwards.Cause links together at the iron-clad two ends up and down, upwards warpage is understood at the two ends of following iron-clad 200 under the effect of power F1, F2, and then drive insulating body 300 two ends are bent upwards, the solder joint 3100 at insulating body 300 two ends places can be because solder crack and breaking circuit plate, make that this electric connector can't operate as normal, have a strong impact on the electric connection between chip and the circuit board.

Therefore, be necessary to design a kind of novel electric coupler component, to overcome above-mentioned defective.

[summary of the invention]

The purpose of this utility model is to provide a kind of electric coupler component, to guarantee that excellent electrical property is connected between chip and the circuit board.

In order to reach above-mentioned creation purpose, the utility model electric coupler component, can be installed on the circuit board, include electric connector, electric connector be provided with main body and can be connected with subject activity be fixed on fixture in the main body in order to will dock electronic building brick, this fixture is two rocking bars that are oppositely arranged, suppress the both sides of chip module respectively, this electric coupler component also comprises movable part that main body can be fixed on the circuit board and the backboard that can match with movable part, and this backboard is positioned at the opposite side that electric connector is set on the circuit board.

Compared with prior art, the utility model electric coupler component has solved the problem that causes the pad solder crack of insulating body two ends because internal stress destroys, thereby eliminated a big hidden danger, strengthened the reliability that this connector uses greatly, guaranteed that excellent electrical property is connected between chip and the circuit board.
