Detailed Description

Please refer to fig. 1 and fig. 2, which are a perspective view and an exploded 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 and first waterproof glue 14 (UV glues), 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 used for the inner shell 12 to be inserted into the opening 132, a section difference 136 is defined between the opening 132 and the insertion opening 122, wherein the outer shell 13 is located at the periphery of the opening 132 and is bent outwards to form a limiting structure 138, the limiting structure 138 and the inner shell 12 together define a filling space 16, and the first waterproof glue 14 is filled in the filling space 16 to shield a first gap between the inner shell 12 and the outer shell 13. In addition, the second waterproof glue 18 (UV glue) is filled in a position of a second gap 106 formed between the rear end of the inner housing 12 and the base 100 (refer to fig. 4).

At least one fixing pin 139 is disposed on each of two sides of the outer housing 13, and at least one closed protrusion 126 protruding toward the installation space 120 is formed on at least one wall of the inner housing 12. The closed protrusion 126 of the inner housing 12 can not only ensure that water or moisture does not flow into the product from the blanking gap of the elastic sheet, but also have a good insertion and extraction feeling. The inner housing 12 is provided with a fastening structure 128, the outer wall surface of the inner housing 12 is located at the fastening structure 128 and is provided with a sheet 2, the inner housing 12 is formed by bending an iron piece, so the fastening structure 128 is formed at the joint of the bottom, which is also called a dovetail groove, and since the fastening structure 128 is a structural pair, a first gap is inevitably generated, so that water or moisture can be effectively prevented from flowing into an assembly gap of the inner and outer housings through the fastening structure 128 of the inner housing 12 and entering the inside of a product by attaching a sheet (MYLAR) to the fastening structure 128.
