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.
Operation lid 4 is a long frame shape member, and it is installed on the insulating body 2 and can moves up and down to drive conducting terminal 3 with respect to insulating body 2.Operation lid 4 has an opening 41 that supplies chip module to insert from the top.The a pair of two ends of long sidewall 42 of operation lid 4 extend to form four reference columns 43 straight down, and the end of reference column 43 is provided with trip 431.Reference column 43 slides up and down in the guide channel 213 of insulating body 2, and trip 431 is used for cooperating with guide channel 213 interior projections 2130, can prevent to operate lid 4 and come off from insulating body 2.Another relative two shorter side walls 44 of operation lid 4 are provided with some holding tanks 45.
Extremely shown in Figure 5 like Fig. 3; Conducting terminal 3 is by the sheet metal punch forming; It comprises base portion 30, the fixed part 33 that is provided with to three welding foots 34 that extend below, by base portion 30 horizontal-extendings by base portion 30 and by base portion 30 upwardly extending first elastic arm 31 and second elastic arms 32.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 the center 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 like 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 location 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 through 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 accomplished, 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.Through the covering effect of cover plate 52, can prevent effectively that conducting terminal 3 especially is infected with by foreign matter such as scruff etc. near the part of circuit board surface, and further prevent the mutual short circuit between the conducting terminal 3.
