[embodiment]
Refer to shown in Fig. 1 to Fig. 4, electric connector 100 of the present invention is used for being electrically connected chip module (not shown) and circuit board (not shown), and this electric connector 100 comprises insulating body 1, is somely housed in conducting terminal (not shown) in insulating body 1 and earth terminal 2 and some tin balls 400 earth terminal 2 being welded to circuit board.
Please consult shown in Fig. 3 to Fig. 4 by emphasis, insulating body 1 be made up of insulating material, and it comprises the interface 11 and installed surface 12 that are oppositely arranged.The holding slot 10 that insulating body 1 also comprises accepting hole (not shown), run through interface 11 and the accepting groove 13 of installed surface 12 and be connected with accepting groove 13.Accepting hole is used for accommodating conducting terminal, and accepting groove 13 and holding slot 10 are used for accommodating earth terminal 2.Accepting groove 13 is roughly trapezoidal shape and the roughly rectangular shape of holding slot 10.Insulating body 1 also comprises the tin ball holding tank (not shown) upwards caved in from installed surface 12, is used for being installed with tin ball 400.The interface 11 of insulating body 1 is coated with metal level 4, and holding slot 10 has inwall (non-label), and this inwall is also coated with metal level 4.Holding slot 10 has the guide portion 17 tilted to holding slot 10 from interface 11, and holding slot 10 bootstrap portion 17, to having junction 18, this guide portion 17 and junction 18 is all coated with metal level 4.The interface 11 of insulating body 1 upwards protrudes out the projection 15 being provided with contiguous accepting groove 13, and this projection 15 can prevent chip module from excessively pressing down in the process pressed down, and causes the distortion of conducting terminal or earth terminal 2.
Please consult shown in Fig. 2 by emphasis, earth terminal 2 comprises main part 20, main body 20 and upwards extends and protrude from the contact site 21 of interface 11, main body 20 to the weld part 22 of downward-extension and main body 20 to side and the holding parts 23 extended straight up.Holding parts 23 upwards bends extension and is provided with kink 24, and kink 24 extends straight up and is provided with extension 25.Extension 25 be convergent setting to the width of holding parts 23, and namely the width of kink 24 is greater than the width of holding parts 23 and the width of extension 25 is greater than the width of kink 24.Extension 25 and holding parts 23 in the vertical direction be arranged in parallel.Holding parts 23 is provided with one and protrudes out the tongue piece 27 of holding parts 23 and the opening 26 corresponding with tongue piece 27, tongue piece 27 is formed from holding parts 23 punching press and peels off on opening 26, the lower end 270 of tongue piece 27 is connected to the bottom of holding parts 23, tongue piece 27 protrudes from the plane at holding parts 23 place and the rightabout bending that protrudes out along tongue piece 27 of kink 24, that is, tongue piece 27 and kink 24 lay respectively at the not homonymy of holding parts 23.
Refer to shown in Fig. 1 and Fig. 4, time in the accepting groove 13 that the earth terminal 2 of electric connector 100 of the present invention is assembled into insulating body 1 and holding slot 10, accepting groove 13 and holding slot 10 accommodate earth terminal 2 jointly, the kink 24 of holding parts 23 to be resisted against in guide portion 17 and with plate the metal level 4 be located in guide portion 17 and contact.Tongue piece 27 protrudes out the plane at holding parts 23 place and tongue piece 27 contacts with the plating metal level 4 be located on junction 18, meanwhile, has when flexible tongue piece 27 can contact with the junction 18 it being coated with metal level 4 and does interference engagement.By like this, when earth terminal 2 is housed in holding slot 10, not only tongue piece 27 contacts with metal level 4, kink 24 also contacts with metal level 4, and kink 24 is when being assembled in holding slot 10, junction 18 can make holding parts 23 have the compression stress of a motion in holding slot 10, and makes tongue piece 27 inwardly do elastic compression, the multiaspect that can be grounded between terminal 2 and insulating body 1 is interfered, and then reaches stable in electrical contact.
Should be understood that, the foregoing is only preferred forms of the present invention, be not whole execution modes, the change of those of ordinary skill in the art by reading specification of the present invention to any equivalence that technical solution of the present invention is taked, is claim of the present invention and contains.
