Detailed Description

Please refer to fig. 1 and fig. 2, which are a perspective view and an exploded perspective view of the present invention. Referring to fig. 3 and fig. 4, the structure of the waterproof glue dispensing range and the waterproof rubber ring of the present invention is schematically illustrated.

The utility model relates to a socket electric connector, the utility model discloses a socket electric connector is USB3.0 or USB3.1 connector, socket connector 1 mainly includes insulating main part 10, socket terminal 11, iron-clad 12, colloid shell 13, waterproof rubber ring 14, back stopper 16 and waterproof glue 17, wherein insulating main part 10 contains base 100 and tongue piece 102, base 100 forms a mounting groove 1002 in the bottom surface, each socket terminal 11 sets up in base 100 and tongue piece 102, back stopper 16 sets up in mounting groove 1002 and wears to establish each socket terminal 11, and form a clearance 104 between iron-clad 12 and the base 100, form a gap 106 between back stopper 16 and each socket terminal 11, waterproof glue 17 is located the point in back stopper 16 and is glued and fill in clearance 104 and gap 106 position.

The iron shell 12 defines a mounting space 120 for disposing the insulating body 10, the colloid shell 13 defines a sleeving space 130, an opening 132 at the front end of the sleeving space 130 and a mounting opening 134 at the rear end, wherein the sleeving space 130 is disposed for the iron shell 12, the iron shell 12 is disposed by inserting the mounting opening 134 to the opening 132, the iron shell 12 exposes an injection molding surface 126 at a position adjacent to the opening 132, a ring of annular groove 136 is formed on the outer wall surface of the colloid shell 13, the waterproof rubber ring 14 is disposed by sleeving the annular groove 136 and covers the injection molding surface 126 and a part of the colloid shell 13, and the waterproof rubber 17 is dispensed at the gap 104 and the gap 106 by dispensing, thereby achieving the waterproof effect.
