[embodiment]
Please specifically consult Fig. 1 and shown in Figure 6, the utility model electric connector comprises the insulating body 1 that is provided with plurality of terminals accepting hole 10, be contained in the plurality of conductive terminals 2 in the terminal accommodation holes 10 and be immobilizated in the tin ball 3 of conducting terminal 2 bottoms.Wherein, shown in the drawing in the plurality of terminals accepting hole 10 of insulating body 1 and only accommodated a conducting terminal 2 and a tin ball 3 that is immobilizated in conducting terminal 2 bottoms, but do not influenced enforcement of the present utility model.
Please specifically consult shown in Figure 4, the utility model conducting terminal 2 is by the metal material punch forming, and it comprises: roughly the base portion 20 of rectangular platy structure, extend to form first contact site 21 that roughly is undaform from the middle part of base portion 20 bottoms downwards, the holding parts 22 that extends in the lower lip side direction bending of base portion 20, extend to form second contact site 23 from the middle part of holding parts 22 bottoms downwards, extend upward elastic portion 24 that formation roughly is " S " from the middle part at holding parts 22 tops, the end of own elasticity portion 24 extends and be bent to form cantilever 25.Wherein, first contact site 21 comprises and is tilted to down the last convex extension part 211 of extending, goes up following convex extension part 212, the salient point between last convex extension part 211 and following convex extension part 212 213 that convex extension part 211 reversed dips extend downwards certainly and reach the hook part 214 that upwards is bent to form in the end of following convex extension part 212.Because the structure of first contact site 21 and second contact site 23 is identical and be positioned at same horizontal plane, so herein the structure of second contact site 23 is just repeated no more.The hook part 214 of first contact site 21 and second contact site 23 is from 2 fixing tin balls 3 of the lateral margin of tin ball 3.
Please specifically consult Fig. 2 and Fig. 3 and in conjunction with shown in Figure 6, the upper top of the terminal accommodation holes 10 of insulating body 1 comprises the last cambered surface 101 that roughly is convex structure, the intrados 102 relative with last cambered surface 101 and is used to connect an opposite side 103 of cambered surface 101 and intrados 102.The bottom of terminal accommodation holes 10 is provided with to cave inward and is used to hold the groove 104 of tin ball 3, and described groove 104 comprises lower camber side 105 and the right-angle side 106 relative with lower camber side 105.After conducting terminal 2 inserts terminal accommodation holes 10, the lateral surface of its base portion 20 and holding parts 22 fits in the inboard of the last cambered surface 101 of terminal accommodation holes 10, first contact site 21 of conducting terminal 2 and second contact site 23 are positioned at the inboard of the right-angle side 106 of groove 104, and first contact site 21 and second contact site 23 push the inner edge that tin ball 3 is resisted against lower camber side 105, thereby conducting terminal 2 stably is immobilizated in the terminal accommodation holes 10 of insulating body 1, conducting terminal 2 cooperatively interacts from multiple spot fixing tin ball 3 with terminal accommodation holes 10, and this multiple spot constitutes three-legged structure.
When being assembled in conducting terminal 2 and tin ball 3 in the terminal accommodation holes 10, earlier the upper set of conducting terminal 2 by terminal accommodation holes 10 is loaded in the terminal accommodation holes 10 by tool, at this moment, though conducting terminal 2 is arranged in terminal accommodation holes 10, first contact site 21 and second contact site 23 of the lower bottom part of conducting terminal 2 are not positioned at the optimum position; Then tin ball 3 is assembled in the groove 104 of terminal accommodation holes 10 by the below of terminal accommodation holes 10 and is positioned at the hook part 214 of first contact site 21 and second contact site 23; By tool first contact site 21 and second contact site 23 are pushed downwards again and pushed tin ball 3 and be resisted against lower camber side 105 places, to reach the optimum position.The top of tin ball 3 is resisted against the inner surface of the groove 104 of terminal accommodation holes 10, the part surface at the middle part of tin ball 3 is resisted against the inner edge of the lower camber side 105 of groove 104, another part is resisted against the medial surface of the salient point 213 of first contact site 21 and second contact site 23, the latter half of tin ball 3 is immobilizated in the inboard of the hook part 214 of first contact site 21 and second contact site 23, fixing tin ball 3 when described hook part 214 upwards holds up tin ball 3.First contact site 21 of conducting terminal 2 and the salient point 213 of second contact site 23 and hook part 214 form multi-point support with the inner edge fixing tin ball of the lower camber side 105 of the groove 104 of terminal accommodation holes 10, reach the poised state of best retain strength, first contact site 21 of conducting terminal 2 and second contact site, 23 effective fixing tin balls 3 are to reach preferable stability, tin ball 3 can be immobilizated in the optimum position of terminal accommodation holes 10, to promote the quality of welding.
