[0024] The mechanical optical switch body 1 is covered inside the lower protective shell 41 and the upper protective shell 42 arranged outside the mechanical optical switch body 1 from the upper and lower sides respectively, and the lower protective shell 41 and the upper protective shell 42 are connected by using the sealing card groove 45 to pass the locking bolt 44, and the sealing strip 46 in the sealing card groove 45 is squeezed and deformed to ensure the sealing and improve the waterproofness. At the same time, the inner sealing ring 47 arranged on the inner side of the lower protective shell 41 and the upper protective shell 42 cooperates with the heat dissipation plate 48 to ensure the sealing and provide heat dissipation for the mechanical optical switch body 1, thereby improving the waterproof protection effect of the mechanical optical switch body 1. At the same time, the support assembly 5 is arranged on both sides of the lower protective shell 41 and the upper protective shell 42. After the lower protective shell 41 and the upper protective shell 42 are installed, the support assembly 5 is clamped on the outer side of the connector 2 from the upper and lower sides, and the wire part of the connector 2 is clamped and supported by the support assembly 5, so as to avoid bending and breaking of the wire at the connection between the connector 2 and the mechanical optical switch body 1, and ensure stable use.
[0025] like Figure 5 As shown, the support assembly 5 includes a limit frame 51, which is fixedly connected to the left and right sides of the lower protective shell 41 and the upper protective shell 42 respectively. The limit frame 51 is provided with an outer sliding hole 52 inside, and a guide column 53 is movably connected inside the sliding hole 52. A support plate 54 is fixedly connected to the inner side of the guide column 53, and a support spring 55 located between the limit frame 51 and the support plate 54 is movably sleeved on the outside of the guide column 53.
[0026] When the lower protective shell 41 and the upper protective shell 42 are connected and fixed, the limit frame 51 is clamped on the outer side of the connector 2 from the upper and lower sides, and the inner protective pad 56 on the inner side of the support plate 54 is abutted against the outer wall of the wire of the connector 2. When the lower protective shell 41 and the upper protective shell 42 are tightened and fixed, the guide column 53 is pushed to slide outward along the sliding hole 52 to squeeze the support spring 55. After the lower protective shell 41 and the upper protective shell 42 are fixed, the elastic force of the support spring 55 pushes the support plate 54 inward, so that the support spring 55 clamps the connector 2 and provides support, thereby providing support for the connector 2 to reduce bending and ensure stable use.
[0027] like Figure 3 As shown, the inner sides of the lower protective shell 41 and the upper protective shell 42 are both provided with stepped openings, the inner sides of the stepped openings are movably connected with an inner sealing ring 47 and a heat sink 48 , and the heat sink 48 is movably connected to the inner side of the inner sealing ring 47 .

At the same time, the inner sealing ring 47 is pressed against the heat sink 48 of the mechanical optical switch body 1 and is tightly clamped on the inner side of the stepped passage to ensure sealing.
[0029] like Figure 2 and Figure 3 As shown, notches corresponding to the connection end 3 are provided inside the lower protective shell 41 and the upper protective shell 42, and a rubber ring corresponding to the notch is movably engaged on the outside of the connection end 3.
[0030] The rubber ring located in the notch is used to squeeze the rubber ring when the lower protective shell 41 and the upper protective shell 42 are connected to ensure sealing at the connection end 3.
[0031] like Figure 3 As shown, the outer side of the heat sink 48 is provided with fins extending outside the lower protective shell 41 and the upper protective shell 42 .
[0032] The fins arranged on the outer side of the heat sink 48 assist in improving the heat dissipation effect of the mechanical optical switch body 1 through heat conduction.
[0033] like Figure 1 As shown, the position of the limiting frame 51 corresponds to the position of the connecting head 2 and the connecting end 3 , and the limiting frame 51 is movably engaged with the outer side of the connecting head 2 .
[0034] The position of the limiting frame 51 corresponds to the position of the connector 2, so that the limiting frame 51 is clamped on the outer side of the connector 2 from the upper and lower sides to provide position limiting support for the connector 2.
[0035] like Figure 5 As shown, an inner protective pad 56 is fixedly connected to the interior of the support plate 54 , and the inner protective pad 56 is in contact with the outer wall of the connector 2 .
[0036] The inner protective pad 56 contacts the outer wall of the wire of the connector 2 , thereby reducing the wear on the wire of the connector 2 .
[0037] like Figure 5 As shown, the guide column 53 is arranged in a rectangular shape, and a limiting convex edge 57 is arranged on the outer side of the guide column 53.
[0038] The guide post 53 is limited by the limiting protrusion 57 to ensure that the guide post 53 is located in the sliding hole 52 and slides stably.
[0039] The working principle of the waterproof mechanical optical switch is described in detail below.
[0040] like Figures 1 to 5As shown, by inserting the connector 2 corresponding to the connection end 3 into the left and right sides of the mechanical optical switch body 1, and by inserting the mechanical optical switch body 1 into the lower protective shell 41 from the top, the bottom of the mechanical optical switch body 1 contacts the top of the inner sealing ring 47 that is clamped on the inner bottom surface of the lower protective shell 41, and then by clamping the upper protective shell 42 on the top of the mechanical optical switch body 1, by making the lower protective shell 41 and the upper protective shell 42 fit each other and by using the sealing card groove 45 to pass through the locking bolts 44 on the outside of the lower protective shell 41 and the upper protective shell 42 to connect and fix the lower protective shell 41 and the upper protective shell 42, by squeezing the sealing strip 46 located in the sealing card groove 45 on the inner side of the lower protective shell 41 and the upper protective shell 42 to provide sealing, and at the same time, by tightening the lower protective shell 41 and the upper protective shell 42, the heat sink 48 fits the outer wall of the mechanical optical switch body 1 and squeezes The inner sealing ring 47 pressed on the inner side of the lower protective shell 41 and the upper protective shell 42 provides sealing at the connection between the lower protective shell 41 and the upper protective shell 42 and the heat sink 48. The lower protective shell 41 and the upper protective shell 42 provide protection and sealing for the mechanical optical switch body 1, and cooperate with the heat sink 48 to ensure the heat dissipation of the mechanical optical switch body 1. When the lower protective shell 41 and the upper protective shell 42 are connected and fixed, the limit frame 51 is clamped on the outer side of the connector 2 from the upper and lower sides, and the inner protective pad 56 on the inner side of the support plate 54 is abutted against the outer wall of the wire of the connector 2. When the lower protective shell 41 and the upper protective shell 42 are tightened and fixed, the guide column 53 is pushed to slide outward along the sliding hole 52 to squeeze the support spring 55. After the lower protective shell 41 and the upper protective shell 42 are fixed, the elastic force of the support spring 55 pushes the support plate 54 inward so that the support spring 55 clamps the connector 2 to provide support.
[0041] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
