DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention, wherein the same components are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0023] Reference Figure 1-7 As shown, a waterproof rocker switch includes a housing 1 with a concave cavity 11, and a toggle member 2 and a conductive component 3 arranged in the housing 1. A gland 4 is rotatably connected to the opening of the concave cavity 11 of the housing 1. Figure 1 , 3 As shown, rotating shafts are coaxially arranged on both sides of the gland 4 , and shaft holes for rotating shafts are provided on the housing 1 , so that the gland 4 can effectively rotate on the housing 1 .
[0024] The swing arm 21 of the toggle member 2 extends outward from the opening of the cavity 11 and is connected to the pressure cover 4. The pressure cover 4 can drive the toggle member 2 to swing in the cavity 11 during the rotation of the shell 1. The conductive component 3 includes a moving contact 31 arranged on the toggle member 2 and a static contact 32 arranged in the cavity 11. The moving contact 31 is arranged in a rod-shaped structure made of conductive metal, and the static contact 32 is arranged in a sheet-shaped structure made of conductive metal. The static contact 32 is provided with an abutment surface 323 for the moving contact 31 to abut. The toggle member 2 is provided with a pressure spring 22 that allows the moving contact 31 to elastically press against the abutment surface 323; the moving contact 31 is movably connected to the toggle member 2, and the static contact 32 is fixedly installed at the bottom of the cavity 11. When the toggle member 2 swings to the point where the moving contact 31 corresponds to the static contact 32, the pressure spring 22 can press the moving contact 31 against the abutment surface 323 of the static contact 32.
[0025] The static contact 32 is provided with three pieces and includes a power contact 321 and two device contacts 322. It is a well-known technology and adopts a common design. In actual use, the power contact 321 can be electrically connected to the power supply, and the device contact 322 can be electrically connected to the device. One power contact 321 is located on one side of the toggle member 2, and the two device contacts 322 are located on the other side of the toggle member 2. Two abutting surfaces 323 are provided on one power contact 321, and one abutting surface 323 is provided on each of the two device contacts 322. The moving contact 31 and the pressure spring 22 are provided in two groups and are respectively provided corresponding to the two device contacts 322. During the swinging process of the toggle member 2, one moving contact 31 abuts against the power contact 321 and one device contact 322, and the other The moving contact 31 also abuts against the power contact 321 and the other device contact 322 in a first state, one moving contact 31 abuts against the power contact 321 and the one device contact 322 and the other moving contact 31 is separated from the power contact 321 and the other device contact 322 in a second state, and one moving contact 31 is separated from the power contact 321 and the one device contact 322 and the other moving contact 31 is also separated from the power contact 321 and the other device contact 322 in a third state.
[0026] The rocker switch in the present application is electrically connected through the rod-shaped moving contact 31 and the abutment surface 323 on the sheet-shaped static contact 32. When the two are in contact, they are in at least line contact, which is beneficial to increase the contact area, thereby helping to improve the stability of the rocker switch. At the same time, it is also convenient to drive the moving contact 31 and the static contact 32 to abut or separate through the swing of the toggle member 2, thereby realizing the switching operation of the rocker switch, and allowing the abutment surface 323 to be arranged in an arc-shaped structure, which can further increase the contact area between the moving contact 31 and the static contact 32, thereby further helping to improve the stability of the rocker switch.
[0027] A sliding groove 23 for the moving contact 31 to slide is provided on the toggle member 2. The direction in which the moving contact 31 slides in the sliding groove 23 is close to or away from the static contact 32. The pressure spring 22 is located on the side of the moving contact 31 away from the static contact 32. The pressure spring 22 elastically abuts between the moving contact 31 and the toggle member 2. When the toggle member 2 swings to the state where the moving contact 31 and the static contact 32 are separated, the moving contact 31 can be abutted against the end of the sliding groove 23. The setting of the slide groove 23 can not only enable the moving contact 31 to slide on the toggle member 2, but also limit the moving contact 31 from slipping off the toggle member 2. When the toggle member 2 swings to the state where the moving contact 31 and the static contact 32 are separated, the moving contact 31 is pressed against the lower end of the slide groove 23 by the pressure spring 22. At this time, the height of the moving contact 31 should be slightly lower than the height of the abutment surface 323. When the toggle member 2 swings to the state where the moving contact 31 and the static contact 32 are connected, the abutment surface 323 will push the moving contact 31 to slide upward for a certain distance, so that the pressure spring 22 can always press the moving contact 31 against the static contact 32 in this state, thereby improving the stability of the conductive component 3 in the electrically connected state.
[0028] It should also be noted here that since the movable contact 31 can be set in a round rod-shaped structure, when the toggle member 2 swings to the state where the movable contact 31 is connected to the static contact 32, the round movable contact 31 can also roll onto the abutment surface 323, which is beneficial to improve the swinging flexibility of the toggle member 2 and facilitate the user to control the swing of the toggle member 2 through the pressure cover 4.
[0029] The bottom of the toggle member 2 is slidably connected with a sleeve 24, and the sliding direction of the sleeve 24 on the toggle member 2 is close to or away from the bottom of the cavity 11. The bottom of the sleeve 24 is movably connected with a positioning ball 25. A positioning spring 26 that can press the positioning ball 25 against the bottom of the cavity 11 is arranged between the toggle member 2 and the sleeve 24. A positioning rib 12 is convexly provided on the inner wall of the bottom of the cavity 11. Two positioning ribs 12 are arranged, and a positioning groove 13 that can limit the positioning ball 25 is formed between the two positioning ribs 12. The setting of the sliding sleeve 24 can prevent the positioning spring 26 from directly contacting the positioning ball 25, thereby affecting the flexibility of the rotation of the positioning ball 25. The positioning ball 25 is movably connected to the bottom of the sliding sleeve 24, which can effectively improve the flexibility of the rotation of the toggle member 2 when it swings. The positioning spring 26 is pressed against the upper end of the sliding sleeve 24, and the positioning ball 25 is pressed to the bottom of the cavity 11 through the sliding sleeve 24. In combination with the positioning convex ridges 12 and the positioning grooves 13, it is convenient to limit the active stroke of the toggle member 2.
[0030] The toggle member 2 is provided with a sliding groove 27 for the sliding sleeve 24 to partially sink into and slide. The outer wall of the sliding sleeve 24 is slidably arranged with the inner wall of the sliding groove 27. The upper end of the sliding sleeve 24 is provided with a plug-in groove 241 for partially inserting the positioning spring 26. The outer diameter of the sliding sleeve 24 is matched with the inner diameter of the sliding groove 27, which is conducive to improving the stability of the sliding sleeve 24 sliding in the sliding groove 27, and further to improving the positioning stability of the toggle member 2. The provision of the plug-in groove 241 can be limited by the positioning spring 26, which is conducive to the positioning spring 26 stably driving the sliding sleeve 24 to slide, thereby facilitating improving the positioning stability of the toggle member 2.
[0031] A wedge block 242 is convexly disposed on the outer wall of the sliding sleeve 24, and an escape notch 28 is provided on the toggle member 2 for the sliding movement of the wedge block 242. The provision of the wedge block 242 can facilitate the sliding sleeve 24 to be embedded in the sliding groove 27, and prevent the sliding sleeve 24 from sliding out of the sliding groove 27, which makes it easier to disassemble and assemble the rocker switch.
[0032] The bottom of the sliding sleeve 24 is provided with an embedding hole 243 for active connection of the positioning ball 25, the inner diameter of the embedding hole 243 is slightly larger than the outer diameter of the positioning ball 25, and a limiting rib 244 for limiting the slipping of the positioning ball 25 is provided at the opening of the embedding hole 243. The inner diameter of the limiting rib 244 should be slightly smaller than the outer diameter of the positioning ball 25, so that the positioning ball 25 can be embedded in the embedding hole 243 conveniently, and the positioning ball 25 can also be easily rotated in the embedding hole 243, which is conducive to improving the swing flexibility of the toggle member 2.
[0033] The opening of the concave cavity 11 of the housing 1 is embedded with a waterproof member 5, and a sealing hole 51 is provided in the middle of the waterproof member 5 for the swing arm 21 to pass through. The opening of the concave cavity 11 of the housing 1 is detachably connected with a mounting frame 6 for mounting the waterproof member 5. The waterproof member 5 can be made of flexible silicone and embedded in the opening of the concave cavity 11 to play a waterproof role. The inner diameter of the sealing hole 51 should be slightly smaller than the outer diameter of the swing arm 21, so as to improve the waterproof effect. The mounting frame 6 can be made of hard plastic, which can be referred to Figure 3 , 4 , the housing 1 can be easily disassembled and assembled through the snap-fit structure.
[0034] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
