Preferably, at least one fixing foot is respectively arranged on two sides of the outer shell.
Preferably, the socket electrical connector is a USB3.0 connector or a USB3.1 connector.
In summary, according to the above embodiments, after the inner and outer housings are assembled, the silica gel can prevent water or steam from flowing into the inside of the product through the assembly gap between the outer structure (product) and the connector housing and the assembly gap between the inner and outer housings, and the positioning protrusion of the housing can play a role in reinforcing the positioning of the silica gel after injection molding, so that the silica gel is not easy to fall off.
In addition, the closed convex part of the inner shell can ensure that water or steam can not flow into the product from the blanking clearance of the elastic sheet, and has better plugging hand feeling.
Furthermore, the inner shell is an iron sheet bent, so that a clamping structure (dovetail groove) is required, and a sheet (MYLAR) is attached to the clamping structure, so that water or steam can be effectively prevented from flowing into an assembly gap between the inner shell and the outer shell through the clamping structure of the inner iron shell and entering the inside of a product.
Furthermore, the UV glue arranged in the groove of the base can fill the assembly gap between the base and the inner shell because the contour of the UV glue is higher than that of the surface of the base, so that water or steam can be prevented from passing through the assembly gap, and the groove can be completely filled because the UV glue is in a glue dispensing mode.

Detailed Description
Please refer to fig. 1 and fig. 2, which are a perspective view and an exploded perspective view of the present invention. The utility model relates to a socket electric connector, the utility model discloses a socket electric connector is USB3.0 connector or USB3.1 connector, socket electric connector 1 major structure includes insulating main part 10, socket terminal 11, interior casing 12, shell body 13, silica gel 14 and UV glue 15, insulating main part 10 contains base 100 and tongue piece 102, each socket terminal 11 sets up in base 100 and tongue piece 102, interior casing 12 has defined installation space 120, interface 122 and has put into mouth 124, installation space 120 supplies to set up insulating main part 10, interface 122 is located interior casing 12 one side and communicates with installation space 120, and it then is located and puts into mouth 124 opposite side and communicates with installation space 120 to put into mouth 124. The outer housing 13 defines a sleeving space 130, an opening 132 and an installation opening 134, the sleeving space 130 is provided for the inner housing 12, the opening 132 is located at the front end of the sleeving space 130, the installation opening 134 is located at the rear end and is provided for the inner housing 12 to be inserted into the opening 132, a step 136 (refer to fig. 3) is defined between the opening 132 and the insertion opening 134, wherein the outer housing 13 is provided with a plurality of positioning protrusions 138 at the opening 132, and in addition, at least one fixing pin 139 is respectively disposed at two sides of the outer housing 13. Silica gel 14 sets up in the poor 136 position of section and covers part inner casing 12 and part shell body 13 with injection moulding, covers the location convex part simultaneously, can play the positioning action of reinforceing silica gel after injection moulding, enables the difficult drop of silica gel, and this silica gel lets more promotion on the whole preparation efficiency through injection moulding, and shows more the optimization to waterproof coefficient.
