[0023] For reference Figures 1-6 One embodiment of this utility model provides a waterproof connection structure, which includes a camera 10 and a connecting cable 20. The connecting cable 20 is plugged into the camera 10 to form an electrical connection. (See reference...) Figure 2 and Figure 5 The camera 10 has a mounting slot 11, which can be located on the back of the camera 10. The bottom surface 111 of the mounting slot 11 has an insertion hole 12 and a connection hole 13. (See reference...) Figure 3 and Figure 6 The connecting cable 20 includes a cable body 21, a plug 22, and a mounting plate 23. The plug 22 of the connecting cable 20 is inserted into the socket 12 of the camera 10 to form an electrical connection. The mounting plate 23 connects the cable body 20 and the plug 22. The mounting plate 23 has a through hole 231 for further assembly. Figure 1 Fastener 30 passes through through hole 231 and extends into connection hole 13 to fix mounting plate 23 in mounting groove 11, wherein fastener 30 is preferably screw. To prevent water or gas from entering the camera 10 from the gap between the camera 10 and the connecting cable 20, the waterproof connection structure also includes a first waterproof ring 40. When mounting plate 23 is fixed in mounting groove 11, the first waterproof ring 40 is located on the outer periphery of plug 22, and one side of the first waterproof ring 40 abuts against the side of mounting plate 23 facing away from cable 21, and the other side of the first waterproof ring 40 abuts against the bottom surface 111 of mounting groove 11.

[0024] In this embodiment, the fastener 30 can firmly fix the mounting plate 23 in the mounting groove 11 and press the first waterproof ring 40 to fully seal the mounting plate 23 and the bottom surface 111 of the mounting groove 11, so as to prevent external water or gas from entering the interior of the camera 10 through the gap between the camera 10 and the connecting line 20.

[0025] In one specific embodiment, refer to Figure 5 and Figure 6 The first waterproof ring 40 is fixed to the side of the mounting plate 23 facing away from the body 21. The first waterproof ring 40 is located on the outer periphery of the plug 22 and is spaced apart from the plug 22.

[0026] Furthermore, the mounting plate 23 has a first annular groove (not shown) on the side facing away from the body 21. The first annular groove is used to install the first waterproof ring 40. The through hole 231 is located on the outer periphery of the first annular groove and the first waterproof ring 40, and a portion of the first waterproof ring 40 extends out of the first annular groove. In this embodiment, the first waterproof ring 40 does not cover the through hole 231, which can reduce the size of the first waterproof ring 40 and the amount of materials needed. In this case, the first waterproof ring 40 can prevent external water or gas from entering the interior of the camera 10 through the gap between the plug 22 and the socket 12.

[0027] Preferably, there are two through holes 231 and two connecting holes 13, with the two through holes 231 arranged opposite each other on both sides of the first annular groove.

[0028] In yet another specific embodiment, the first waterproof ring 40 is not disposed on the mounting plate 23 of the connecting cable 20, but is disposed in the mounting slot 11 of the camera 10, as can be seen from [reference needed]. Figure 2 and Figure 3 The first waterproof ring 40 is disposed on the bottom surface 111 of the mounting groove 11. The first waterproof ring 40 is located on the outer periphery of the socket 12 and is spaced apart from the socket 12.

[0029] Furthermore, the bottom surface 111 of the mounting groove 11 is provided with a second annular groove (not shown in the figure). The second annular groove is used to install the first waterproof ring 40. The connecting hole 13 is located on the outer periphery of the second annular groove and the first waterproof ring 40, and a part of the first waterproof ring 40 extends out of the second annular groove.

[0030] In this embodiment, the first waterproof ring 40 does not cover the connection hole 13, which can reduce the size of the first waterproof ring 40 and the amount of materials needed. At this time, the first waterproof ring 40 can prevent external water or gas from entering the interior of the camera 10 through the gap between the plug 22 and the socket 12.

[0031] Preferably, there are two through holes 231 and two connecting holes 13, with the two connecting holes 13 arranged opposite each other on both sides of the second annular groove.

[0032] In a preferred embodiment, to prevent external air and water from entering the camera 10 through the gap between the mounting groove 11 and the mounting plate 23, a second waterproof ring 24 is provided on the outer periphery of the mounting plate 23. When the mounting plate 23 is fixed in the mounting groove 11, the outer periphery of the second waterproof ring 24 abuts against the side wall of the mounting groove 11, which can further improve the waterproof effect.

[0033] In a preferred embodiment, to prevent external air and water from entering the camera 10 through the gap between the fastener 30 and the through hole 231, the waterproof connection structure also includes a third waterproof ring 50. One end of the third waterproof ring 50 abuts against the mounting plate 23, and the other end of the third waterproof ring 50 abuts against the head of the fastener 30, which can further improve the waterproof effect.

[0034] In a preferred embodiment, reference may be made to Figure 4 , Figure 4 The diagram shows the structure of the plug 22. The plug 22 has a protrusion 221 at the end connected to the mounting plate 23. The width of the protrusion 221 gradually decreases along the insertion direction of the plug 22. In this embodiment, the gradually decreasing width of the protrusion 221 ensures that the fit between the plug 22 and the socket 12 becomes increasingly tight during insertion, until the plug 22 can no longer be inserted. On one hand, the protrusion 221 can cover the opening of the socket 12 to further enhance the waterproof effect. On the other hand, if the plug 22 is pressed down excessively or the fastener 30 is installed too tightly during insertion, the presence of the protrusion 221 can prevent damage to the structure inside the socket 12.

[0035] In a preferred embodiment, reference may continue to be made to... Figure 4 The plug 22 has a foolproof groove 222 on its side, and the socket 12 has a foolproof protrusion 121 on its side wall. When the plug 22 is inserted into the socket 12, the foolproof protrusion 121 is received in the foolproof groove 222. In this embodiment, the foolproof groove 222 and the foolproof protrusion 121 can prevent the plug 22 from being inserted backwards; when the plug 22 is inserted backwards, the plug 22 cannot be inserted into the socket 12. Preferably, see reference. Figure 4 The plug 22 has a cuboid structure, and the anti-fooling groove 222 is formed by recessing in the middle of the larger side of the plug 22 along the width direction of the plug 22.

[0036] In a preferred embodiment, since it is necessary to fix the mounting plate 23 in the mounting groove 11, and the gap between the mounting plate 23 and the mounting groove 11 is small, the connecting cable 20 further includes a connecting shell 25 to facilitate the placement of the mounting plate 23 into the mounting groove 11. One end of the connecting shell 25 is fixed to the side of the mounting plate 23 away from the plug 22, and the other end of the connecting shell 25 is fixed to the outer periphery of the cable body 21. In this embodiment, the mounting plate 23 can be conveniently placed into the mounting groove 11 by holding the connecting shell 25.

[0037] Preferably, the connecting shell 25 and the mounting plate 23 are integrally formed, and the connection between the connecting shell 25 and the wire 21 is coated with UV glue. Alternatively, the connecting shell 25 and the mounting plate 23 are not integrally formed, but the connection between the two is also coated with UV glue, which can prevent external air or water from entering the connecting wire 20.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
