Description

Technical Field

[0001] The utility model relates to the technical field of travel switches, in particular to a travel switch with a waterproof function. Background Art

[0002] A travel switch is a commonly used low-current main control electrical appliance. The collision of mechanical moving parts is used to cause the contacts to move, thereby connecting or disconnecting the control circuit and achieving a certain control purpose. The travel switch is generally in a vertical state when in use. The connection terminal and the trigger terminal of the travel switch in the vertical state are both perpendicular to the ground. When moisture comes into contact with the travel switch, the water will flow into the interior of the travel switch through the connection terminal and the trigger terminal, which can easily cause a short circuit. At present, in order to make the travel switch waterproof, waterproof covers are put on the connection terminal and the trigger terminal. However, there are gaps between the waterproof covers and the trigger terminal and the connection terminal, and a tight fit cannot be achieved, and the problem of poor waterproof effect still exists. Therefore, the utility model provides a travel switch with a waterproof function to solve the above-mentioned problems. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1 to 4 In the embodiment of the present invention, a travel switch with a waterproof function includes a housing 1, an installation cavity 2 is provided inside the housing 1, a wiring core 3 for wiring is fixedly connected inside the installation cavity 2, a shell cover 4 is buckled on the upper end of the housing 1, a trigger switch 5 is inserted at the left end of the housing 1, a waterproof head is provided at the end of the trigger switch 5 away from the housing 1, and the end of the waterproof head away from the housing 1 is set into a rounded shape, and a waterproof cover 6 is provided on the outside of the trigger switch 5, the outer diameter of the waterproof head is larger than the inner diameter of the waterproof cover 6, and specifically, the waterproof cover 6 is set in a truncated cone shape. The small-diameter end of the waterproof cover 6 contacts the waterproof head, and the large-diameter end of the waterproof cover 6 contacts the outer wall of the housing 1. The waterproof cover 6 can prevent water from flowing from the outer wall of the trigger switch 5 into the housing 1 (specifically, when the utility model is normally used, the housing 1 is placed vertically, that is, the trigger switch 5 is facing upward, and the waterproof head is set to a rounded shape to prevent water from flowing into the waterproof cover 6). A release switch 7 for releasing the trigger switch 5 is also provided on the outer wall of the housing 1. The release switch 7 and the trigger switch 5 are both existing technologies and will not be described in detail here.

[0023] A waterproof tube 8 is fixedly connected to the end of the housing 1 away from the trigger switch 5. A plurality of clamping heads 9 are fixedly connected to the end of the waterproof tube 8 away from the housing 1, and the plurality of clamping heads 9 do not contact each other. A rubber sleeve 10 for waterproofing is fixedly connected to the interior of the waterproof tube 8. A rotating cap 11 is threadedly connected to the exterior of the waterproof tube 8. A clamping sleeve 12 is fixedly connected to the end of the rotating cap 11 away from the housing 1. The inner wall of the rotating clamping sleeve 12 is arranged in an inclined shape. The clamping sleeve 12 can be squeezed by rotating it toward the housing 1, thereby clamping the cable using the clamping sleeve 12.

[0024] Example 2: Please refer to Figure 3 and Figure 4Based on Example 1, the rubber sleeve 10 is set to a funnel shape, and the diameter of the end with the smallest diameter of the rubber sleeve 10 is smaller than the outer diameter of the cable. The end with the small diameter of the rubber sleeve 10 is set to a retracted end 16, and the retracted end 16 is folded inwardly in the rubber sleeve 10, which is convenient for wiring. The end of the clamping sleeve 12 away from the rotating cap 11 is fixedly connected to the threaded sleeve 13, and the external thread of the threaded sleeve 13 is connected to the rotating head 14. The internal movably connected to the rotating head 14 is a tensioning wire 15. The end of the tensioning wire 15 away from the rotating head 14 is fixedly connected to the retracted end 16 of the rubber sleeve 10. Specifically, the internal rotatable connection of the rotating head 14 is a rotating ring, and the tensioning wire 15 is fixedly connected to the rotating ring. More specifically, the tensioning wire 15 is in the gap between the plurality of clamping heads 9.

[0025] The working principle of this utility model is:

[0026] When the utility model is used, the wiring end of the cable is inserted into the housing 1 from the end of the waterproof tube 8, and then the cable is connected to the wiring core 3. After the connection is completed, the shell cover 4 is covered, and then the rotating cap 11 is rotated in the direction of the housing 1. The cable is clamped and fixed by the mutual cooperation of the rotating cap 11 and the clamping head 9, thereby preventing the cable from being pulled and affecting the connection between the cable and the wiring core 3. At the same time, it can also prevent water from flowing into the housing 1 from the outer wall of the cable.

[0027] When the cable is clamped, the rotating head 14 is rotated to move it away from the housing 1. At this time, the tightening wire 15 will pull the retracted end 16 in the rubber sleeve 10, causing the retracted end 16 to move outward. At this time, the rubber sleeve 10 will be fully expanded. At this time, the rubber sleeve 10 will form a complete funnel shape. At this time, the end with a smaller diameter of the rubber sleeve 10 will be close to the rotating cap 11. This can increase the waterproof effect of the rubber sleeve 10, and then water will flow into the housing 1 along the outer wall of the cable.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
