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 the HDMI connector, and socket connector 1 mainly includes insulating main part 10, socket terminal 11, interior casing 12, shell body 13 and first waterproof glue 14, 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, supplies a waterproof 3 (rubber ring) 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 leg 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 step 15 (as shown in fig. 3) is defined between the opening 132 of the outer shell 132 and the insertion opening 122 of the inner shell 12, and the first waterproof adhesive 14 is formed at the step 15 and seals a structural gap 136 between the inner shell 12 and the outer shell 13 at the opening 132. Wherein the first waterproof glue 14 is coplanar with the front end of the inner shell 12.

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 127 (dovetail groove), the outer wall surface of the inner housing 12 located on the fastening structure 127 is provided with a sheet 128, the inner housing 12 is mainly formed by bending an iron piece, and the abutting side edges are respectively fixed by the fastening structure 127, so that a gap is inevitably generated between the two, and the sheet 128 covers the gap to prevent the external moisture from entering.

Furthermore, a gap 129 is formed between the rear end of the inner housing 12 and the base 100, and the gap 129 is filled with a second waterproof glue 2 (see fig. 4), so that the gap 129 is sealed by the second waterproof glue 2 to prevent moisture from passing through.

Fig. 3, 4 and 5 are combined to form a first waterproof adhesive, a cross-sectional structure of the socket connector, and a structure of filling a second waterproof adhesive according to the present invention. As can be seen from fig. 3, the first waterproof glue 14 is mainly formed at the position of the step 15 by dispensing the first waterproof glue 14, and after the outer shell 13 is sleeved outside the inner shell 12, a structural gap 136 is formed between the outer shell 13 and the inner shell 12, so that the first waterproof glue 14 is formed at the position of the step 15, which can effectively seal the structural gap 136 between the inner shell 12 and the outer shell 13 at the position of the opening 132, and after dispensing the first waterproof glue 14, the position thereof is coplanar with the front end of the inner shell 12. Therefore, the technical problem of adopting liquid resin does not exist, and the problems of assembly and the waterproof effect of the connector cannot be influenced.
