The lug 621 gone out.
Described main board 61 is coated and fixed on hyoplastron 11 lower end, and fixed part 62 is fixed with insulator 1.Tool
For body, described main board 61 outer rim is folded upward at forming some bound edges 611, this main board 61 mid portion
It is formed with the convex closure 612 raised up；Described hyoplastron 11 lower end is provided with for engaging for described main board 61
Installation position, described main board 61 is fastened in this installation position.
Described metal reinforcing plates 6 can effectively strengthen firmness degree and the stability of hyoplastron 11, though repeatedly with
After circumscribed USB plug is to inserting, hyoplastron 11 also will not be damaged, improves the service life of the present invention, equally can
Ensure and the stability being connected between circumscribed USB plug.It addition, described metal reinforcing plates 6 does not increase hyoplastron
The thickness of 11 and width, metal reinforcing plates 6 assemble with hyoplastron 11 after integral thickness and width and USB association
Thickness and the width of specification hyoplastron are corresponding, say, that the structure of hyoplastron 11 does not interferes with circumscribed USB and inserts
The normal use of head.
In sum, the present invention is after metal shell 3 is coated and fixed on insulator 1, in described insulator 1
Marine glue is filled with sealing, formation the first weight waterproof construction between rear perpheral and metal shell 3 inwall；Described
Plastic jacket 5 be to be taken shape in by jetting formation process that metal shell 3 is peripheral and rear end, salable for making
The gap produced in place of the head end of the metallic plate of one-tenth metal shell 3 and joining distal ends, forms the second weight waterproof construction；
After being taken shape on metal shell 3 by jetting formation process due to plastic jacket 5, plastic jacket 5 and insulator
1 rear end face one is fixing, and the formation peripheral with metal shell 3 of plastic jacket 5 inwall is seamless applying fixing, with
Form comprehensive sealing, and as triple waterproof constructions；In the present invention when being assemblied in electronic product, can
Form sealing by sealing ring 52 with electronic product to be connected, as quadruple waterproof construction.So, the present invention
There is quadruple waterproof construction so that having highly desirable waterproof efficacy, it addition, the present invention also to have structure steady
Fixed, the advantage of high life, so that being greatly improved the market competitiveness of the present invention.
