Detailed Description
Fig. 1, fig. 2 and fig. 3 show a schematic perspective view, a schematic exploded perspective view and a schematic sectional structure of a waterproof ring according to the present utility model. Referring to fig. 4 and fig. 5, a schematic structural diagram of a dispensing range of the waterproof adhesive and a schematic structural diagram of the 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, socket terminals 11, an iron shell 12, a colloid shell 13, silica gel 14, a waterproof ring 15, 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 forms a circle of grooves 1000 on the peripheral wall surface and a mounting groove 1002 on the bottom surface, each socket terminal 11 is arranged on the base 100 and the tongue piece 102, the rear plug 16 is arranged in the mounting groove 1002 and penetrates through each socket terminal 11, and a gap 104 is formed between the rear plug 16 and each socket terminal 11. The iron shell 12 defines a mounting space 120 for mounting the insulating main body 10, the rubber shell 13 defines a housing space 130, an opening 132 at the front end of the housing space 130 and a mounting opening 134 at the rear end, wherein the housing space 130 is used for mounting the iron shell 12, the iron shell 12 is arranged in a manner that the mounting opening 134 is inserted into the opening 132, the iron shell 12 is positioned adjacent to the opening 132 to expose an injection molding surface 126, a circle of annular groove 136 is formed on the outer side wall surface of the rubber shell 13, the silica gel 14 is formed in the annular groove 136 in an injection molding manner and covers the injection molding surface 126 and part of the rubber shell 13, in addition, the waterproof ring 15 is made of rubber material, is sleeved on the groove 1000 through the elastic effect of the waterproof ring and is abutted against the inner surface of the iron shell 12, and the waterproof ring 17 is dotted in the gap 104 in a glue dispensing manner, so that the waterproof effect can be achieved.
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.
