There is provided a shielding casing 6 for third step.The collecting that the terminal module 200 is sheathed on into the shielding casing 6 is empty Between in 600.One is constituted between the hyoplastron 12 and the receiving space 600 and docks chamber 601.The shielding casing 6 is compared with pedestal 11 Protrude backward and form accommodating cavity 602 therebetween, and the internal face (non-label) of the accommodating cavity 602 is provided with guide ramp 604, the guide ramp 604 is enclosed around receiving space 600 1.The opening 631 of the rear end of shielding casing 6 is made to supply the pedestal 11 projection 113 is spacing to be supported.Making the front end face 111 of the pedestal 11, to be held in the holding piece 64 forward described to prevent Terminal module 200 is moved forward.

There is provided a metallic support 8 for four steps.By the main part 81 of the metallic support 8 and the both sides of the main part 81 Welding foot 83 outer surface of the shielding casing 6 is immobilizated in by welding.

There is provided liquid repellent glue for 5th step.Make in the liquid repellent glue is provided with along the accommodating cavity 602 The guide ramp 604 of wall (non-label), which is flowed into the accommodating cavity 602 and solidified, forms the water-proof slab 7, guide ramp 604 portion rear end is exposed to the rear of water-proof slab 7.The liquid repellent glue during filling liquid waterproof glue The accommodating cavity 602 is uniformly filled in flowing in the through slot 1413 of the first through slot 1313 and second.Make the waterproof Offset plate 7 blocks the gap between the pedestal 11 and the shielding casing 6, to prevent liquid from penetrating into electronic equipment (not shown) In.Because the shielding casing 6 itself does not form any gap, therefore the electric connector 100 is made to have with reference to the water-proof slab 7 There is more preferable water resistance.

Compared with prior art, the utility model has the advantages that：The utility model power supply terminal extends back Go out two weld parts being separated from each other, can further strengthen the welding effect that is soldered on circuit board and shunt high current.

Some embodiments of the present utility model are the foregoing is only, the embodiment being not all of, the common skill in this area Art personnel are by any equivalent change read the utility model specification and taken technical solutions of the utility model Claim of the present utility model is covered.
