Description of the symbols

The socket connector 1, the insulating body 10, the base 100, the groove 1000, the tongue piece 102, the socket terminal 11, the inner iron shell 12, the mounting space 120, the protrusion 122, the engaging structure 124, the sheet 126, the outer iron shell 13, the sheathing space 130, the fixing leg 131, the opening 132, the mounting opening 134, the protruding structure 136, the waterproof glue 14, and the waterproof ring 15.

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, socket connector 1 mainly includes insulating main part 10, socket terminal 11, interior shell 12, outer shell 13, waterproof glue 14 and waterproof circle 15, wherein insulating main part 10 contains base 100 and tongue piece 102, base 100 defines a recess 1000, each socket terminal 11 sets up in base 100 and tongue piece 102, interior shell 12 is defined to have installation space 120 for setting up insulating main part 10, outer shell 13 is defined to overlap and is established space 130 and be located the cover and establish opening 132 of space 130 front end department and the installing port 134 of rear end department, wherein the cover is established space 130 and is supplied interior shell 12 to set up, in addition, outer shell 13 both sides set up an at least fixed foot 131 respectively, interior shell 12 sets up the mode and is inserted to opening 132 position by installing port 134, and set up plural number protrusion structure 136 in the neighbouring opening 132 department of outer shell 13 outer wall, and each protrusion structure sets up in the outer shell 13 outside wall with the mode of establishing the conflict with the ring mode, waterproof glue 14 then forms the mode and sets up in outer shell 13 and the fixed groove structure 136 is interfered with waterproof glue 15 the recess 1000 and waterproof circle 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. 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 4 are also shown, which are schematic views of the cross-sectional structure of the waterproof ring and the structure of the waterproof glue. As can be seen from fig. 3 and fig. 2, after the socket terminals 11 are disposed on the base 100 and the tongue piece 102, the waterproof ring 15 is sleeved, the waterproof ring 15 is mainly sleeved on the groove 1000, and after the insulating main body 10 is inserted into the iron shell 12, the waterproof ring 15 on the base 100 is tightly contacted with the inner surface, and the waterproof ring 15 is squeezed and deformed to form a sealing and waterproof effect, so as to achieve a better waterproof effect.

It can be known from fig. 4 that, after the above operations are completed, the waterproof glue 14 is mainly formed on the outer iron shell 13 and near the opening 132 by injection molding, and the protruding structure 136 disposed on the outer side wall of the outer iron shell 13 near the opening 132 can make the waterproof glue 14 be fixed by structural interference after injection molding, so as to avoid sliding, and therefore, the waterproof glue blocks the moisture from outside to inside, thereby achieving the waterproof effect.

Through the above, by utilizing the convex structure 136 arranged on the outer side wall surface of the outer iron shell 13 adjacent to the opening 132, since the waterproof glue 14 is liquid silica gel, the waterproof glue 14 can be interfered and fixed by the convex structures 136 when being formed on the outer iron shell 13 by injection molding, so that the waterproof effect can be achieved, and the waterproof glue is installed in an injection molding mode, so that the technical problem of adopting liquid resin does not exist, and the waterproof effect problem of assembling and connecting devices cannot be influenced.
