[specific embodiment]

Fig. 1 to Fig. 6 is please referred to, the utility model electric connector 100 is for being electrically connected a chip module, the electrical connection Device 100 include with several terminal grooves 11 insulating body 10 and several be contained in the terminal in the terminal groove 11 20.The insulating body 10 has upper surface 12 and lower surface 13, and the terminal groove 11 runs through the insulating body upper and lower surfaces 12,13；The terminal 20 tilts the sub-arm 22 of extension including main part 21, from 21 upper limb of main part upwards, is connected to It the welding foot 23 of 21 lower edge of main part and is folded upward at from 21 lower edge of main part and extends to the sub-arm 22 The elastic arm 24 of top.

Please emphasis refering to Fig. 5, the elastic arm 24 includes from 21 lower edge of main part obliquely upward towards far from main part First bending part 241 of 21 direction bending extension is folded upward at the vertical portion extended vertically from first bending part 241 242, second bending for extending and being located above the sub-arm 22 is tilted from the vertical portion 242 towards 21 direction of main part Portion 243 continues the contact portion extended from the rake 244 of second bending part 243 bending extension and from the rake 244 245, the contact portion 245 is in arc-shaped and raises upward, and the contact portion 245 is electrically connected with the chip module.

Fig. 5 and Fig. 6 are please referred to, the main part 21 is retained in the terminal groove 11, and the two sides of the main part 21 are set There are bur and 11 interference engagement of terminal groove, the vertical portion 242 is housed in floating manner in the terminal groove 11, institute It states elastic arm 24 and the welding foot 23 to extend from the left and right ends of 21 lower edge of main part respectively, the sub-arm 22 is certainly 21 upper limb of main part is tilted towards the direction far from the elastic arm 24 to be extended.

Fig. 1 to Fig. 6 is please referred to, the upper surface 12 of the insulating body 10 has the boss 14 protruded upward, the elasticity Arm 24 stretches out the boss 14, second bending part 243, the part contact portion 245 and the sub-arm 22 upwards Between the upper surface 12 and the boss 14, the chip module is compressed downwards so that the elastic arm 24 is because of stress deformation And it is in electrical contact with the sub-arm 22, until the elastic arm 24 contacts with the boss 14 and stops deformation, it is arranged such Be conducive to the electric connector 100 to be come into full contact with the chip module to realize stable electrically conduct.
