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 primary structure includes insulating main part 10, socket terminal 11, interior casing 12, shell body 13, silica gel 14 and waterproof circle 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 is defined there is installation space 120, interface 122 and puts 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, it then is located to put into mouth 124 opposite side and communicates with installation space 120 to put into mouth 124. The outer shell 13 defines a sleeving space 130, an opening 132 and an installation opening 134, the sleeving space 130 is provided for the inner shell 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 shell 12 to be inserted into the opening 132, a step 136 is defined between the opening 132 and the insertion opening 134, wherein the outer shell 13 is located at the opening 132 and is provided with a plurality of positioning protrusions 138, and in addition, two sides of the outer shell 13 are respectively provided with at least one fixing pin 139. Silica gel 14 is arranged at the position of the segment difference 136 in an injection molding mode and covers part of the inner shell 12 and part of the outer shell 13, and the positioning convex part is covered, so that the positioning effect of the reinforced silica gel after injection molding can be achieved, the silica gel is not easy to fall off, the overall manufacturing efficiency of the silica gel is improved through the injection molding mode, and the waterproof coefficient is optimized.
