Detailed Description

Please refer to fig. 1, fig. 2 and fig. 3, which are schematic perspective views, schematic exploded perspective views and schematic sectional structure views of the waterproof ring according to the present invention. Referring to fig. 4 and 5, the structural schematic diagram of the waterproof glue dispensing range and the structural schematic diagram of the waterproof rubber ring of the present invention are shown.

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, waterproof ring 15, back stopper 16 and waterproof glue 17, wherein insulating main part 10 contains base 100 and tongue piece 102, base 100 forms round recess 1000 and forms a mounting groove 1002 in the bottom surface in the perisporium face shape, 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 back stopper 16 and each socket terminal 11. The iron shell 12 defines a mounting space 120 for disposing the insulating main 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, the waterproof rubber ring 14 and the waterproof ring 15 are both made of rubber, and are sleeved on the groove 1000 by the elastic effect of the waterproof rubber ring 14 and abut against the inner surface of the iron shell 12, and the waterproof rubber 17 is disposed at the gap 104 by dispensing, thereby achieving the waterproof effect.
