Detailed Description

Fig. 1 and 2 show a perspective view and an exploded perspective view of the present utility model. Referring to fig. 3 and fig. 4, a schematic structural diagram of a dispensing range of the waterproof adhesive and a schematic structural diagram of the formed silica gel are shown.

The utility model relates to a socket electric connector, which is a USB3.0 or USB3.1 connector, wherein the socket electric connector 1 mainly comprises an insulating main body 10, a socket terminal 11, an iron shell 12, a colloid shell 13, silica gel 14, a rear plug 16 and waterproof glue 17, wherein the insulating main body 10 comprises a base 100 and a tongue piece 102, the base 100 is provided with a mounting groove 1002 on the bottom surface, each socket terminal 11 is arranged on the base 100 and the tongue piece 102, the iron shell 12 is defined with a mounting space 120 for arranging the insulating main body 10, a gap 104 is formed between the iron shell 12 and the base 100, the colloid shell 13 is defined with a sleeving space 130, an opening 132 positioned at the front end of the sleeving space 130 and a mounting opening 134 positioned at the rear end, wherein the sleeving space 130 is used for arranging the iron shell 12, the iron shell 12 is inserted into the opening 132, the iron shell 12 is positioned adjacent to the opening 132, an injection molding surface 126 is exposed, a ring-shaped groove 136 is formed on the outer side wall surface of the colloid shell 13, the silica gel 14 is formed on the ring-shaped groove 136 in an injection molding manner and covers the glue surface 126 and part of the injection molding surface 126, and a gap 104 is formed between the waterproof plug 16 and the socket electric connector, and the waterproof glue terminal is arranged at the gap 106, and the gap 106 is formed between the socket electric connector and the socket electric connector is filled with the waterproof plug 11.

In addition, at least one wall surface of the iron shell 12 is provided with at least one protruding part 122 protruding towards the installation space 120, the protruding part 122 is of a closed structure, not only has better inserting and pulling hand feeling, but also can prevent water from entering the product from the protruding part 122, and because the iron shell 12 is made of iron sheets which are bent, the iron shell is required to be provided with an engaging structure 128 (dovetail slot), and a sheet 18 (MYLAR) is attached to the engaging structure 128, so that water or water gas can be effectively prevented from flowing into an assembling gap of the inner and outer shells through the engaging structure 128 of the inner iron shell 12 to enter the product.
