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 the HDMI connector, and socket connector 1 mainly includes insulating main part 10, socket terminal 11, interior casing 12, shell body 13, first silica gel circle 14 and second silica gel circle 15, and wherein insulating main part 10 contains base 100 and tongue piece 102, and each socket terminal 11 sets up in base 100 and tongue piece 102, and wherein base 100 forms a fixed slot 104, is supplied first silica gel circle 14 cover to establish fixedly by fixed slot 104.

The inner housing 12 defines a mounting space 120 for disposing the insulating body 10, and a socket 122 at one side and a disposing opening 124 at the other side of the inner housing 12.

The outer shell 13 defines a sleeving space 130, an opening 132 at the front end of the sleeving space 130, and an installation opening 134 at the rear end, wherein the sleeving space 130 is provided for the inner shell 12, in addition, at least one fixing pin 131 is respectively disposed at two sides of the outer shell 13, the inner shell 12 is disposed by inserting the installation opening 134 into the opening 132, a section difference 16 (as shown in fig. 3) is defined between the opening 132 of the outer shell 13 and the insertion opening 122 of the inner shell 12, the inner shell 12 is located at the insertion opening 122 and is bent outward to form a bending positioning portion 123, the structural position of the bending positioning portion 123 on the inner shell 12 is mainly bent at a corresponding edge, and the second silicone ring 15 is sleeved at the section difference 16 and seals a structural gap 136 between the inner shell 12 and the outer shell 13 at the opening 132.

At least one wall of the inner housing 12 forms at least one protrusion 121 protruding toward the installation space 120, and the protrusion 121 is of a closed structure. In addition, the inner housing 12 is provided with a fastening structure 125 (dovetail groove), the outer wall surface of the inner housing 12 located on the fastening structure 125 is provided with a sheet 126, the inner housing 12 is mainly formed by bending an iron piece, and the abutting side edges are respectively fixed by the fastening structure 125, so that a gap is inevitably generated between the two, and the sheet 126 covers the gap to prevent the external moisture from entering.
