[embodiment]
Fig. 1 to Fig. 5 is the preferred embodiment of electric connector of the present invention, electric connector 1 of the present invention is used to connect chip module 8 to printed circuit board (PCB) 6, and it comprises that mainly insulating body 2, two rows arrange and are placed in conducting terminal 3 (only indicating a conducting terminal in the accompanying drawing) in the insulating body 2 relatively, are installed on the insulating body 2 and operation lid 4 that can move up and down with respect to insulating body 2 and the dust guard 5 that is arranged at insulating body 2 bottoms.
As shown in Figure 2, insulating body 2 is a rectangular configuration, and it comprises flat body 21, and the middle part of body 21 is provided with a button that runs through up and down and holds hole 211.An opposite end of body 21 respectively is provided with row's terminal containing slot 212 and is assembled in wherein for conducting terminal 3.A support slot 214 is respectively offered in the both sides of each row's terminal containing slot 212 on insulating body 2.In addition, four corners of insulating body 2 respectively are provided with a guide channel 213, and the top in the guide channel 213 is provided with projection 2130.
Extremely shown in Figure 5 as Fig. 3, conducting terminal 3 is by the sheet metal punch forming, it comprises base portion 30, is reached by base portion 30 upwardly extending first elastic arm 31 and second elastic arms 32 by three weld parts 34 of base portion 30 extension downwards, the fixed part 33 that is provided with by base portion 30 horizontal-extendings.Fixed part 33 is used for conducting terminal 3 is fixed on the terminal containing slot 212 of insulating body 2.First elastic arm 31 wriggles from base portion 30 and extends, and its middle part is provided with an elastic portion 311, thus elastic portion 311 upper end bifurcateds extension formation first contact site 313 and press sections 312.First contact site 313 contacts with the top of the conductive feet 80 of chip module 8 both sides.Second elastic arm 32 tilts to extend upward, and it is terminal to form second contact site, 321, the second contact sites 321 and can contact with the bottom of the conductive feet 80 of chip module 8.
Extremely shown in Figure 5 as Fig. 4, the rectangular box-like structure that dust guard 5 is formed in one, it comprises the substrate 51 that is positioned at relative both sides, respectively is provided with a pair of through hole 511 on the substrate 51.Thereby the upwards vertical respectively bending in the relative both sides of another of dust guard 5 forms a rectangle dust cap 52.
During assembling electric connector 1, at first with conducting terminal 3 from the terminal containing slot 212 of the horizontally mounted insulating body 2 of side, to operate lid 4 then is added on the insulating body 2, make the reference column 43 of operating lid 4 be arranged in the guide channel 213 of insulating body 2, the press section 312 of conducting terminal 3 is inserted in the holding tank 45 of operation lid 4 simultaneously.In addition, between operation lid 4 and the insulating body 2 spring 7 is housed, spring 7 can impel operation lid 4 to return to initial position in the elastic force that operation lid 4 presses down the back generation.Place insulating body 2 belows also together to place on the circuit board dust guard 5, the welding foot 34 of conducting terminal 3 inserts and also is soldered to circuit board 6.In addition, upwards pack into from circuit board 6 bottoms by screw (not shown), it passes the location hole 511 of dust guard 5 and is locked in the insulating body 2.After electric connector 1 assembling was finished, the substrate 51 of dust guard 5 was positioned at the bottom of insulating body 2, and dust cap 52 is positioned at insulating body 2 two ends and hides in the side of the base portion 30 of conducting terminal 3, and the two ends of dust cap 52 are arranged in the support slot 214 on the insulating body 2.By the covering effect of cover plate 52, can prevent effectively that the part of the especially close circuit board surface of conducting terminal 3 is infected with by foreign matter such as scruff etc., and further prevent the mutual short circuit between the conducting terminal 3.
In addition, the dust cap of electric connector of the present invention also can be arranged to other structure, as adopt two independently dust cap also can realize the effect of roughly the same protection terminal this moment to be assembled in the side of two row's terminals respectively.
