Preferably, at least one wall surface of the iron shell is formed with at least one protruding portion protruding toward the installation space.

Preferably, the convex portion is a closed structure.

Preferably, the rear end of the iron shell extends a plurality of fixing feet.

Preferably, each receptacle terminal defines a DIP solder foot.

Preferably, the iron shell is provided with a clamping structure, and the outer wall surface of the iron shell is provided with a sheet at the clamping structure.

Preferably, the receptacle electrical connector is a stand-up connector.

Preferably, the socket electrical connector is a USB3.0 or USB3.1 connector

In summary, the glue dispensing surface of the iron shell exposed near the opening is mainly provided with the UV glue in a glue dispensing and light curing manner, and the assembly gap defined by the glue shell and the iron shell is sealed by the UV glue, so that not only can the waterproof effect be achieved, but also the technical problem of liquid resin is not existed due to the formation manner of the UV glue, so that the waterproof effect problem of assembly and connector is not affected, and furthermore, the gap and the gap are sealed by the waterproof glue point, thereby improving the overall waterproof effect again by a waterproof stage number.

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 glue and a schematic structural diagram of the formed UV glue of the present utility model are shown.

The utility model relates to a socket electric connector, which is a USB3.0 or USB3.1 connector, and the socket electric connector 1 mainly comprises an insulating main body 10, a socket terminal 11, an iron shell 12, a colloid shell 13, UV glue 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 forms a mounting groove 1002 at the bottom surface, each socket terminal 11 is arranged on the base 100 and the tongue piece 102, the iron shell 12 defines 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 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 used for arranging the iron shell 12, the iron shell 12 is inserted into the opening 132 by the mounting opening 134, the iron shell 12 is arranged at a position adjacent to the opening 132 to expose a point glue surface 126, the colloid shell 13 and the iron shell 12 define an assembly gap 136, in addition, the rear plug 16 is arranged in the mounting groove 1002 and penetrates each socket terminal 11, a gap 104 is formed between the rear plug 16 and the socket terminal 11, and the waterproof glue gap 106 can be filled in the gap 106.
