So, be necessary to design a kind of novel electric connector, to overcome above-mentioned defective.

[summary of the invention]

The purpose of this utility model is to provide a kind of electric connector, and it can guarantee to have between chip module and circuit board preferably and electrically connect, and takies the less space of circuit board.

In order to reach above-mentioned creation purpose, the utility model electric connector, comprise electrical connector body and will dock the fixture that electronic component is fixed in the body and butt joint electronic component and electrical connector body are electrically conducted, wherein body comprises insulating body and conducting terminal, it is characterized in that: fixture comprises at least two pairs of fixed bodies that can cooperatively interact and mobile, and this mobile directly is pressed on the butt joint electronic component.

Compared with prior art, it is with fixture chip module and body to be fixed on the circuit board, realized the electric connection between chip module and circuit board, the distortion of body influences the electric connection between chip module and circuit board when having avoided the fixed chip module again.

[embodiment]

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

Shown in Fig. 1 to 4, the utility model electric connector 1 comprises electrical connector body 10 and fixture 11, be used to electrically connect chip module 2 and circuit board 3, body comprises insulating body 12 and conducting terminal 16, wherein conducting terminal is fixed in the insulating body 12, chip module 2 is put in the insulating body 12 and contacts with conducting terminal 16 compressions, and fixture 11 comprises bolt 13 and backboard 14.

Wherein insulating body 12 is made up of sidewall 120 all around and middle depressed part 121, and the inboard of sidewall 120 has the location division 122 of chip module, conducting terminal comprises a fixed part (not icon), be fixed in the accommodation hole (not drawing among the figure) of insulating body 12, the upper surface that protrudes in insulating body 12 recess 121 that one inclination elastic arm 161 turns forward, thus help contacting with the chip module compression.

Wherein circuit board 3 is provided with aperture 30, backboard 14 be provided with vertically upward extend double-screw bolt 15 and its in be provided with screwed hole 150, the upper surface that this double-screw bolt 15 stretches out in circuit board 3 by the aperture on the circuit board 3 30 is positioned on the position at four angles of body, the lower surface of the head 130 of bolt 13 directly is pressed in the upper surface of chip module 2, its main part 131 matches with screwed hole 150, thereby chip module is fixed in the body, realize the electric connection between chip module and circuit board, avoided the flexural deformation of insulating body and reduced taking up room of electric connector.
