[embodiment]
Fig. 1 to Fig. 6 is first better embodiment of the utility model electric connector 100, in the present embodiment, electric connector 100 is in order to electrically connecting chip module (not shown) to circuit board (not shown), and it comprises insulating body 10 and is arranged on plurality of conductive terminals 20 on the insulating body 10.Insulating body 10 is the tabular structure, which is provided with and somely be arranged and run through the upper surface 101 of insulating body 10 and the terminal hole 11 of lower surface 102, conducting terminal 20 is housed in respectively in the terminal hole 11, and each conducting terminal 20 all has the last contact site 21 that extends insulating body 10 and reaches contact site 22 down.Last contact site 21 is used to connect the chip module, and following contact site 22 is used for the connecting circuit plate.
Please join Fig. 2 to shown in Figure 4, the diagonal L of insulating body 10 is provided with two variform first location holes 12 and second location hole 13, and first location hole 12 and second location hole 13 lay respectively on the diagonally opposing corner of insulating body 10.First location hole 12 has along a pair of vertical plane 121 of the diagonal L extension of insulating body 10 and connects this a pair of curved surface 122 to vertical plane 121.First location hole 12 is that first size D1 is second dimension D 2 greater than first location hole 12 along the overall dimension perpendicular to the diagonal L direction along the overall dimension of the diagonal L direction of insulating body 10.Second location hole 13 is a circular hole, is provided with in it somely evenly to distribute along its periphery and be the first cantilever-shaped flexure strip 131.Be provided with in first location hole 12 from its vertical plane 121 upper limbs and extend downwards and be cantilever-shaped a pair of second flexure strip 123.
