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 HDMI connector, socket connector 1 mainly includes insulating main part 10, socket terminal 11, iron-clad 12, colloid shell 13 and first waterproof glue 14, wherein insulating main part 10 contains base 100 and tongue 102, each socket terminal 11 sets up in base 100 and tongue 102, iron-clad 12 defines installation space 120 for setting up insulating main part 10, colloid shell 13 defines the cover and establishes space 130 and is located the opening 132 of cover establishment space 130 front end department and the installing port 134 of rear end department, wherein the cover establishes space 130 and supplies iron-clad 12 to set up, iron-clad 12 sets up the mode and inserts to opening 132 position by installing port 134, and form round annular groove 136 at colloid shell 13 outside wall, form at least one convex part 1360 in annular groove 136, and convex part 1360 sets up with the ring mode, first waterproof glue 14 is formed at annular groove 136 and cladding convex part 1360.

The protrusion 1360 is annularly formed in the annular groove 136. In addition, at least one wall of the iron shell 12 forms at least one protrusion 122 protruding toward the installation space 120, and the protrusion 122 is of a closed structure. Furthermore, a gap 15 is formed between the mounting opening 134 and the rear end of the iron shell 12 of the colloid shell 13 and the base 100, the colloid shell 13 and the base 100 are in the same plane at the mounting opening 134 and the rear end of the iron shell 12, and the second waterproof glue 16 fills and shields the gap 15 in the plane to prevent water and air from passing through. Furthermore, a plurality of fixing legs 124 extend from the rear end of the iron shell 12, each fixing leg 124 forms an opening 1240, when each fixing leg 124 is soldered on the circuit board, the solder can flow through the openings 1240 to increase the firmness of the overall soldering fixation, and the length of the colloid shell 13 is the same as that of the iron shell 12.

Fig. 3 and 4 are also shown, which are a schematic view of the combination of the first waterproof glue and the second waterproof glue. As can be seen from fig. 3, the first waterproof glue 14 is mainly liquid silica gel, and therefore the glue injection manner is to inject the glue into the mold first, and then the glue shell 13 is formed on the mold, and at this time, the first waterproof glue 14 can be completely formed in the annular groove 136 and covers the convex portion 1360, and the first waterproof glue 14 can block external moisture from entering between the socket connector 1 and the assembled product, thereby blocking the moisture from the outside to the inside, so that the waterproof effect can be achieved, and the technical problem of adopting liquid resin does not exist due to the formation manner of the first waterproof glue, and therefore the waterproof effect problem of the assembly and the connector cannot be affected.

As can be seen from fig. 4, the colloid shell 13 forms a gap 15 between the mounting opening 134 and the rear end of the iron shell 12 and the base 100, the colloid shell 13 is coplanar with the base 100 at the mounting opening 134 and the rear end of the iron shell 12, and the waterproof glue 16 fills and shields the gap 15 on the plane to seal the gap, thereby preventing external moisture from passing through the gap.

Moreover, the socket connector 1 of the present invention is vertical, so the plural fixing pins 124 extend from the rear end of the iron shell 12, and can be directly disposed on the circuit board in a vertical manner, and the openings 1240 on the fixing pins 124 can increase the stability of the fixing with the circuit board (as shown in fig. 3), and further, the lengths of the colloid shell 13 and the iron shell 12 are the same, so the colloid shell 13 can completely cover the iron shell 12, and the waterproof effect is further improved.

Through the above, the first waterproof glue 14 is formed in the annular groove 136 and covers the protrusion 1360, the second waterproof glue 16 is filled in the gap 15, and the glue shell 13 and the iron shell 12 have the same length, so that the glue shell 13 can not only achieve waterproof performance by completely covering the iron shell 12, but also achieve waterproof performance through the formation of the first waterproof glue 14 and the second waterproof glue 16, and more effectively solve the technical problem of liquid resin, and thus the waterproof performance of the assembly and the connector is not affected.
