[embodiment]
Please refer to shown in Fig. 1 to Fig. 4, the present invention relates to a kind of for being electrically connected the electric connector of chip module (not shown) and circuit board (not shown), described electric connector has some electrical connector elements 100 that are assembled to together, and described electrical connector element 100 comprises body unit 1, is contained in terminal unit 2 and some tin balls 3 in body unit 1.
Please refer to shown in Fig. 2 to Fig. 3, described terminal unit 2 comprises that row's conducting terminal 20 and insert molding have the insulating body 21 of described conducting terminal 20.Described conducting terminal 20 comprises holding parts 201, from holding parts 201, extends upward the elastic arm 202 of setting and the weld part 203 arranging to downward-extension from holding parts 201.Described insulating body 21 is immobilizated in the holding parts 201 of described conducting terminal 20.Described body unit 1 comprises the metallic plate 11 that forms some grids along longitudinally, and described metallic plate 11 has upside and the downside relative with upside.Described metallic plate 11 comprise the first metallic plate 111 of extend arranging along longitudinally and with the first metallic plate 111 the second metallic plate 112 arranged in a crossed manner.In the present embodiment, described the second metallic plate 112 is to be assembled on the first metallic plate 111, and certainly, the second metallic plate 112 also can form with the first metallic plate 111 integrated punchings.Described the second metallic plate 112 has some recesses 110 between upside and downside, and some recesses 110 are arranged in a row along longitudinally, and some grids are interconnected.
Described body unit 1 has the insulation upper cover 12 that is covered in metallic plate 11 upsides, and described insulation upper cover 12 has accepting groove 120.Described body unit 1 also has the insulator foot 14 that is covered in metallic plate 11 downsides, and described insulator foot 14 has ball groove 140.Described metallic plate 11 is insert moldings with described insulation upper cover 12 and described insulator foot 14.Between described insulation upper cover 12 and insulator foot 14, be not insulated filling plastic full, it has clearance space 15.In the present embodiment, between insulation upper cover 12 and insulator foot 14, there is not ambroin to be connected.Described clearance space 15 is to be surrounded by insulation upper cover 12, insulator foot 14 and metallic plate 11.
