[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides Figure 1-4 A waterproof structure shown, a mounting frame 2, the cross section of the mounting frame 2 is in the shape of a square, a plurality of countersunk holes are equidistantly provided at the top and bottom of the optical terminal, a fixing pin 1 is slidably inserted and connected in the inner cavity of the countersunk hole, a plurality of mounting holes are equidistantly provided at the top and bottom of the mounting frame 2, the fixing pin 1 passes through the countersunk hole and is threadedly inserted and connected in the inner cavity of the mounting hole, the mounting frame 2 can be inserted into the side of the optical terminal with the interface, and is installed on the optical terminal through the fixing pin 1, thereby extending the cavity with the connector socket, which is convenient for waterproofing the side of the optical terminal with the cable connector;

[0029] Furthermore, a waterproof mechanism 3 is provided inside the mounting frame 2, and the waterproof mechanism 3 includes: a sleeve plate 31, a telescopic plate 32, a rubber pad 33, a compression spring 34 and a linkage assembly 35, wherein the plurality of sleeve plates 31 are respectively fixedly connected to the top and bottom ends of the inner wall of the mounting frame 2; the plurality of telescopic plates 32 are respectively slidably and interlacedly connected with the inner cavities of the plurality of sleeve plates 31; the plurality of rubber pads 33 are respectively fixedly connected to the opposite sides of the plurality of telescopic plates 32; the plurality of compression springs 34 are equidistantly arranged inside the sleeve plate 31, one end of the plurality of compression springs 34 are all fixedly connected to the telescopic plate 32, and the other ends of the plurality of compression springs 34 are all fixedly connected to the inner wall of the sleeve plate 31, and the plurality of compression springs 34 are always in a compressed state, so that a stable elastic force can be provided to the rubber pad 33 through the telescopic plate 32, so that the two opposite rubber pads 33 can be tightly squeezed together, and the external cable must be connected to the connector of the optical terminal. When making a connection, the two telescopic plates 32 can be pulled to open the rubber pads 33 so that the connection can be made, and the telescopic plates 32 can be loosened after the connection. At this time, the two rubber pads 33 can squeeze the cables inserted into the interface. Since the rubber pads 33 are elastic, during the squeezing process, these cables will sink into the rubber pads 33, and at the same time, the rubber pads 33 will also fit tightly against the outer wall of the cable, thereby forming a complete closed space, which effectively protects the functional interface of the optical terminal and realizes the waterproof function of the optical terminal interface. At the same time, the cable can be clamped, which can effectively prevent the cable from falling off during use; the linkage component 35 is arranged between the multiple telescopic plates 32, which is used to synchronize the multiple telescopic plates 32. The re-plugging of the connecting cable only requires pulling one of the telescopic plates 32 by the pull plate 4 to drive the other telescopic plate to synchronize in the opposite direction, thereby opening the cavity for easy use.

[0030] Specifically, the linkage assembly 35 includes: a limit rod 351, a pulley 352 and a connecting rope 353. The multiple limit rods 351 are respectively fixedly connected to the two sides of the multiple telescopic plates 32. The two sides of the inner wall of the mounting frame 2 are provided with limit grooves. The limit rods 351 are slidably connected with the inner cavity of the limit grooves. The limit rods 351 play a role in limiting the movement of the telescopic plates 32, so that the telescopic plates 32 can only be displaced in the vertical direction along the limit grooves under the elastic force of the compression springs 34; the multiple limit grooves are provided with adjustment grooves on the opposite sides. The pulleys 352 are rotatably arranged inside the adjustment grooves through the rotating shaft. The setting of the pulleys 352 can change the linkage. The movement direction of the connecting rope 353; the connecting rope 353 is located inside the adjusting groove, and the two ends of the connecting rope 353 are fixedly connected to multiple limit rods 351 respectively. The connecting rope 353 cooperates with the pulley 352. When it is necessary to plug or unplug the connecting cable, one of the telescopic plates 32 can be pulled up by the pull plate 4, and then the other telescopic plate 32 can be pulled down by the connecting rope 353, so that the two rubber pads 33 in the middle can be opened for plugging and unplugging. After the plugging and unplugging work is completed, the pull plate 4 is released, so that under the elastic force of the compression spring 34, they can be squeezed against each other again to achieve sealing and anti-detachment of the connecting cable. The operation is simple and convenient.

[0031] Furthermore, a pull plate 4 is fixedly connected to the outer wall of one of the telescopic plates 32, and a slope is provided on the top of the pull plate 4. The pull plate 4 can not only pull the telescopic plate 32 to move, but also cover the gap of the rubber pad 33. The opening of the slope makes it easy to guide water away from the optical terminal, so that the overall waterproof performance is better.

[0032] Furthermore, through grooves are provided on both sides of the optical terminal, and a heat sink is fixedly installed inside the through grooves by bolts. A plurality of heat sinks are equidistantly provided on the outer wall of the heat sink, and the plurality of heat sinks are inclined. The inclined heat sinks prevent water from directly flowing into the interior of the optical terminal through the heat sink, thereby ensuring heat dissipation while having a certain waterproof effect, which is convenient for use.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
