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: the socket comprises an insulation main body 10, socket terminals 11, an inner iron shell 12, an outer iron shell 13, a first waterproof adhesive 14 and a second waterproof adhesive 15, wherein the insulation main body 10 comprises a base 100 and a tongue piece 102, at least one adhesive dispensing groove 1000 and at least one adhesive overflowing groove 1002 adjacent to the adhesive dispensing groove 1000 are defined, each socket terminal 11 is arranged on the base 100 and the tongue piece 102, the inner iron shell 12 is defined with an installation space 120 for arranging the insulation main body 10, the outer iron shell 13 is defined with a sleeving space 130, an opening 132 located at the front end of the sleeving space 130 and an installation opening 134 located at the rear end of the sleeving space, the sleeving space 130 is provided for arranging the inner iron shell 12, in addition, two sides of the outer iron shell 13 are respectively provided with at least one fixing pin 131, the inner iron shell 12 is arranged in a mode of being inserted into the opening 132 from the installation opening 134, a plurality of protruding structures 136 are arranged on the outer side wall of the outer iron shell 13 adjacent to the opening 132, each protruding structure 136 is arranged on the outer side wall of the outer iron shell 13 in a mode of being annularly arranged on the outer iron shell 13, the waterproof adhesive dispensing groove 14 is arranged for accommodating the second waterproof adhesive 15, and the adhesive dispensing groove 1002 is arranged on the waterproof adhesive dispensing groove 15.

At least one wall of the inner iron shell 12 forms at least one protrusion 122 protruding toward the installation space 120, and the protrusion 122 is of a closed structure. The overflow slots 1002 are located on both sides of the dispensing slot 1000. In addition, the inner iron shell 12 is provided with a fastening structure 124 (dovetail groove), the outer wall surface of the inner iron shell 12 located at the fastening structure 124 is provided with a sheet 126, the inner iron shell 12 is mainly formed by bending an iron piece, and the abutting side edges are respectively fixed by the fastening structure 124, so that a gap is inevitably generated between the two, and the sheet 126 covers the gap to prevent the external moisture from entering.

Fig. 3 and fig. 4 are also shown, which are schematic structural diagrams of the section of the second waterproof adhesive formed by injecting glue and the first waterproof adhesive formed by injection molding according to the present invention. After the socket terminals 11 are arranged on the base 100 and the tongue piece 102, glue is injected into the second waterproof glue 15, the second waterproof glue 15 is mainly dispensed at the position of the glue dispensing groove 1000, and the second waterproof glue 15 is tightly contacted with the iron shell 12, so that the second waterproof glue 15 must exceed the surface of the base 100, and glue overflow is easy to occur, and the overflowed second waterproof glue 15 can be accommodated through the adjacent glue overflow groove 1002, so that the influence of the excessive second waterproof glue 15 on peripheral structural assembly is avoided, and a better waterproof effect can be achieved.
