Detailed ways

The detailed description and technical content of the present utility model are as follows with accompanying drawings. However, the accompanying drawings are only provided for reference and illustration, and are not used to limit the present utility model.

Referring to Fig. 1 and Fig. 2, a preferred embodiment of the present invention provides a waterproof connector socket, which preferably complies with the micro USB specification. In this embodiment, the waterproof connector socket of the present invention at least includes an insulating seat 100 and a metal shell 200 , the structure of which is described in detail below.

Referring to FIG. 2 and FIG. 3 , the insulating base 100 is made of plastic injection molding, which includes a body 110 and a tongue 120 , and the body 110 is in the shape of a rectangular block. The tongue piece 120 extends vertically from one side of the body, and is in the shape of a rectangular piece.

The metal casing 200 is in the shape of a cylinder with two ends open, which is formed by bending and surrounding a metal sheet. The two ends of the metal shell 200 are respectively a sleeve end 210 and a plug end 220, and the sleeve end 210 is sealed and sleeved on the outer edge of the body 110 (for example, a A gasket 101 made of silica gel or rubber is used to seal the body 100 and the metal casing 200 ). The insertion end 220 is disposed around the tongue piece 120 . A water-retaining engagement groove 221 is recessed on the inner side of the insertion end 220 , and the water-retaining engagement groove 221 can preferably be made by stamping. A pair of positioning feet 230 extend in the same direction on opposite sides of the metal casing 200 .

In this embodiment, the waterproof connector of the present invention further includes a plurality of metal terminals 300 embedded in the insulating seat 100 . Each metal terminal 300 is formed by bending a strip-shaped metal sheet, and two ends of each metal terminal 300 are a welding end 310 and a lapping end 320 respectively. The welding end 310 of each metal terminal 300 is embedded in the body 110 , and its end passes through the body 110 . In this embodiment, the welding end 310 passes through the body 110 along the direction perpendicular to the tongue 120 and then bends to extend opposite to the tongue 120 along the direction parallel to the tongue 120 , but the utility model does not limit the welding end 310 The form passing through the main body 110 and the extended form after passing through the main body 110 . The overlapping end 320 of each metal terminal 300 extends from the welding end 310, extends from the inside of the body 110 to the inside of the tongue 120, and part of it protrudes from the surface of the tongue 120, and the exposed parts of the overlapping ends 320 are One row is arranged on the surface of the tongue 120 .

In this embodiment, the waterproof connector of the present invention may further include a waterproof ring 400 . The waterproof ring 400 is preferably made of silica gel or rubber, and is sleeved on the outer side of the insertion end 220 of the aforementioned metal shell 200 .

Referring to FIG. 4 and FIG. 5 , in this embodiment, the waterproof connector socket of the present invention is used to be disposed on a circuit board 20 in an electronic device 10 . The insertion end 220 of the metal shell 200 is exposed on the surface of the electronic device 10, and the positioning pin 230 extended by the metal shell 200 is used for welding on the circuit board 20, thereby fixing the waterproof connector socket of the present invention on the circuit board 20 . The welding end 310 of the metal terminal 300 is welded on the circuit board 20 and electrically connected to the circuit board 20 . The waterproof ring 400 is clamped between the metal casing 200 and the electronic device 10 to seal the gap between the outside of the metal casing 200 and the electronic device 10 .
