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, socket connector 1 (be the HDMI connector of vertical type) mainly includes insulating main part 10, socket terminal 11, iron-clad 12, colloid 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, iron-clad 12 is defined and is had installation space 120 for setting up insulating main part 10, and a bayonet 121 that is located iron-clad 12 one side and the entrance 122 of putting of opposite side, the iron-clad is by putting entry 122 department and extending plural fixed foot 123, colloid shell 13 defines the cover and establishes space 130 and is located the cover and establishes opening 132 of 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, defines a segment difference 124 (refer to figure 4) between opening 132 of colloid shell 13 and the bayonet 121 of iron-clad 12, waterproof glue 14 forms in the segment difference 124 position and seals iron-clad 12 with the colloid shell 12 the opening 12 is located the same plane of waterproof glue structure 15 and waterproof circle 15 in the recess front end and waterproof circle 15.

Wherein at least one wall of the iron shell 12 forms at least one protrusion 125 protruding toward the installation space 120, and the protrusion 125 is of a closed structure. The fixing legs 123 form an opening 1230, when the fixing legs 124 are soldered on the circuit board, the solder can flow through the opening 1240 to increase the overall solder fixing firmness, and the length of the rubber housing 13 is shorter than that of the iron housing 12.

Fig. 3 and 4 are also shown, which are a schematic view of the cross-sectional structure of the waterproof ring and a schematic view of 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.

As can be seen from fig. 4, after the above operations are completed, the insulating main body 10, the iron shell 12 and the colloid shell 13 are assembled, and after the operations are completed, since the colloid shell 13 is shorter than the iron shell 12, a step 124 is generated between the opening 132 of the colloid shell 13 and the socket 121 of the iron shell 12, and at this time, the waterproof glue 14 (UV glue) is injected into the step 124, and at this time, the waterproof glue 14 is coplanar with the front end of the iron shell 12, so that the waterproof glue 14 can block external moisture from entering between the socket connector 1 and the assembled product, thereby blocking moisture from outside to inside, and not only reaching the waterproof effect, but also because the waterproof glue 14 is formed, there is no technical problem of using liquid resin, and therefore, the waterproof effect of the assembly and the connector cannot be affected.

Furthermore, the socket connector 1 of the present invention is vertical, so the rear end of the iron shell 12 extends to form a plurality of fixing pins 123, which can be directly vertically disposed on the circuit board, and the openings 1230 on the fixing pins 123 can increase the stability of the fixing between the fixing pins and the circuit board.

Through the above, the waterproof adhesive 14 is formed at the position of the step 124 through the step 124 defined between the opening 132 of the adhesive shell 13 and the socket 121 of the iron shell 12, and the waterproof ring 15 is sleeved in the groove 1000 to abut against the inner surface of the iron shell 12, so as to achieve the waterproof effect. In addition, the iron shell 12 is coated by the colloid shell 13, so the design of the common double-iron shell is better in waterproof coefficient.
