Description

Technical Field

[0001] The utility model relates to the field of electrical technology, in particular to a wall switch. Background Art

[0002] The existing wall switch includes a body, which is provided with a receiving cavity, in which the moving contact, the static contact and the spring are all received, and the handle partially extends into the receiving cavity, and the rest of the handle is exposed outside the body. The operator turns the handle to connect or disconnect the moving contact with the static contact, thereby achieving the opening and closing effect. The spring cooperates with the moving contact to achieve the effect of rapid resetting of the moving contact. When the force applied by the handle on the moving contact disappears, the spring releases energy to form a rapid disconnection.

[0003] However, during the actual assembly process, the spring is installed under the moving contact (one end of the spring is against the accommodating cavity, and the other end is against the moving contact). The spring will give the moving contact a reaction force (causing the moving contact to move upward), resulting in the moving contact being unable to be positioned and fixed. Since the handle and the accommodating cavity are rotationally connected, which is specifically a U-shaped groove and a rotating shaft to form a rotational connection (when the face cover has not been installed, the handle can slide vertically up and down relative to the accommodating cavity), the moving contact will also drive the handle to move in disguise, causing the handle to be in an uncertain state, seriously affecting the subsequent assembly. Utility Model Content

[0004] Therefore, the technical problem to be solved by the utility model is how to realize the installation and fixing of the handle. To this end, a wall switch comprises:

[0005] A body, wherein the body is provided with a receiving cavity;

[0006] A handle, wherein the handle is accommodated in the accommodating cavity, wherein one of the handle and the accommodating cavity is provided with a first rotating shaft hole, and the other of the handle and the accommodating cavity is provided with a rotating shaft cooperating with the first rotating shaft hole, wherein the first rotating shaft hole is provided with an opening and a necked portion, wherein the opening is connected with the necked portion, and the rotating shaft passes over the necked portion and enters into the lowermost end of the first rotating shaft hole.

[0007] The first rotating shaft hole is located in the accommodating cavity, and the accommodating cavity is further provided with a second rotating shaft hole matched with the rotating shaft, and the second rotating shaft hole and the first rotating shaft hole are in opposite directions and are staggered.

[0008] The body includes a surface cover, a middle cover and a base. The surface cover, the middle cover and the base cooperate to form the accommodating cavity. The second rotating shaft hole is located in the middle cover. The handle passes through the middle cover and extends to the outside.

[0009] The base is provided with a support member, and the first rotating shaft hole is located on the support member.

[0010] The handle is provided with a first plane portion, and the side surface of the support member is located on the rotation track of the first plane portion.

[0011] One of the handle and the support member is provided with a limiting column, and the other of the handle and the support member is provided with a limiting notch matched with the limiting column.

[0012] It also includes a moving contact, a static contact and a reset member accommodated in the accommodating cavity, the static contact is located on the movement trajectory of one end of the moving contact, one end of the reset member abuts against the accommodating cavity, and the other end of the reset member abuts against the end of the moving contact away from the static contact, and the handle drives the moving contact to move.

[0013] The handle is provided with a driving part, and the middle area is from the position where the reset member abuts against the moving contact member to the position where the moving contact member cooperates with the static contact member, and the driving part cooperates with the middle area.

[0014] The accommodating cavity is provided with a fixing groove, and one end of the resetting member is accommodated in the fixing groove.

[0015] The fixing groove is provided with a first fixing column, the movable contact member is provided with a first positioning protrusion, one end of the reset member is sleeved on the first fixing column, and the other end of the reset member is sleeved on the first positioning protrusion.

[0017] 1. The utility model provides a wall switch. After the reset member and the moving contact member are fixed, the handle is fixed by the cooperation between the rotating shaft and the first rotating shaft hole. Due to the limitation of the necking portion, the handle cannot move vertically up and down. At this time, the force of the reset member cannot drive the moving contact member and the handle to move, thereby achieving the assembly fixing effect of the handle, preventing the handle from moving, and facilitating subsequent assembly.

[0018] 2. The utility model provides a wall switch, in which the second rotating shaft hole and the first rotating shaft hole form a limiting and fixing effect, further improving the position limitation of the rotating shaft.

[0040] Example 1

[0041] This embodiment provides a wall switch, as shown in the attached Figure 1-7 As shown, including:

[0042] The body 10 is provided with a receiving chamber 100. The body 10 also includes an inlet and an outlet, which are connected through the receiving chamber 100. By rotating the handle 11, the connection or disconnection of the entire electrical circuit is realized.

[0043] The handle 11 is accommodated in the accommodating chamber 100. The handle 11 partially extends into the accommodating chamber 100, and is used to cooperate with the moving contact 12 to drive the cooperation between the moving contact 12 and the static contact 13. Here, the moving contact 12 and the static contact 13 are connected in series in the entire electrical circuit. Here, the moving contact 12 and the static contact 13 can be located on the side close to the incoming line end, or on the side close to the outgoing line end. Those skilled in the art can adjust according to actual needs. One of the handle 11 and the accommodating chamber 100 is provided with a first rotating shaft hole 14, and the other of the handle 11 and the accommodating chamber 100 is provided with a rotating shaft 15 that cooperates with the first rotating shaft hole 14. When the handle 11 is provided with the first rotating shaft hole 14, the accommodating chamber 100 is provided with the rotating shaft 15; conversely, when the handle 11 is provided with the rotating shaft 15, the accommodating chamber 100 is provided with the first rotating shaft hole 14. The first rotating shaft hole 14 is provided with an opening and a constricted portion 141, and the opening is connected to the constricted portion 141. When the rotating shaft 15 is matched with the first rotating shaft hole 14, the rotating shaft 15 enters the first rotating shaft hole 14 through the opening, and then passes over the constricted portion 141 to enter the lowest end of the first rotating shaft hole 14. At this time, the constricted portion 141 restricts the rotating shaft 15 from moving toward the opening side, that is, the rotating shaft 15 can only rotate relative to the first rotating shaft hole 14, and the rotating shaft 15 cannot move vertically up and down, forming a fixing effect of the rotating shaft 15. The size of the constricted portion 141 here is smaller than the size of other positions, forming a narrow mouth effect, and the rotating shaft 15 and the constricted portion 141 are interference fit, and the rotating shaft 15 needs to be punched or squeezed or knocked to make the rotating shaft 15 enter the lowest end of the first rotating shaft hole 14. The lowest end of the first rotating shaft hole 14 is adapted to the rotating shaft 15, and the lowest end of the first rotating shaft hole 14 will not restrict the rotation of the rotating shaft 15. The size of the constricted portion 141 is smaller than the size of the lowermost end of the first shaft hole 14, and the size of the constricted portion 141 is also smaller than the size of the opening position of the first shaft hole 14. The area from the opening of the first shaft hole 14 to the constricted portion 141 can be of equal size or can be gradually reduced. When the reset member and the movable contact member 12 are fixed, the handle 11 is fixed by the cooperation between the shaft 15 and the first shaft hole 14. Due to the limitation of the constricted portion 141, the handle 11 cannot move vertically up and down. At this time, the force of the reset member 17 cannot drive the movable contact member 12 and the handle 11 to move, thereby achieving the assembly fixing effect of the handle 11, preventing the handle 11 from moving, and facilitating subsequent assembly.

[0044] Specifically, as attached Figure 3-5As shown, the first rotating shaft hole 14 is located in the accommodating cavity 100, and the opening of the first rotating shaft hole 14 is facing upward, that is, facing the side of the handle 11. The accommodating cavity 100 is also provided with a second rotating shaft hole 16 that cooperates with the rotating shaft 15. The second rotating shaft hole 16 and the first rotating shaft hole 14 are facing oppositely, that is, the second rotating shaft hole 16 is facing downward. The first rotating shaft hole 14 and the second rotating shaft hole 16 are staggered. The staggered distribution here specifically means that the position where the first rotating shaft hole 14 cooperates with the rotating shaft 15 and the position where the second rotating shaft hole 16 cooperates with the rotating shaft 15 are different. The second rotating shaft hole 16 and the first rotating shaft hole 14 form a limiting fixing effect, further improving the position limitation of the rotating shaft 15. In addition to this embodiment, the second rotating shaft hole 16 may be omitted, and the fixing of the rotating shaft 15 may be achieved only by the constricted portion 141. In addition, the plug structure may be inserted into the first rotating shaft hole 14 to form a limiting fit with the rotating shaft 15.

[0045] Specifically, the number of the first rotating shaft hole 14 and the number of the second rotating shaft hole 16 are both two, and the two first rotating shaft holes 14 are symmetrically arranged, and the two second rotating shaft holes 16 are symmetrically arranged, so as to achieve the limiting effect of the rotating shaft 15, so that the rotating shaft 15 can only rotate radially and cannot move vertically up and down.

[0046] Specifically, as attached Figure 1-6 As shown, the body 10 includes a cover 18, a middle cover 19 and a base 20. The cover 18, the middle cover 19 and the base 20 cooperate to form a receiving chamber 100. Here, the middle cover 19 cooperates with the base 20, and the cover 18 also cooperates with the base 20. A through hole is provided in the middle of the cover 18, and the middle cover 19 passes through the through hole to form an assembly and fixing effect. The cover 18 and the base 20 can be connected by bolts or snaps, etc., and the middle cover 19 and the base 20 can be connected by bolts or snaps. In this embodiment, the middle cover 19 is located on the side close to the input end. The second shaft hole 16 is located on the side of the middle cover 19 facing the base 20. When the handle 11 cooperates with the base 20 to form a positioning and fixing of the shaft 15, the middle cover 19 cooperates with the base 20, so that the second shaft hole 16 cooperates with the shaft 15, and the middle cover 19 and the base 20 jointly form a limit fixation for the handle 11 to prevent it from moving vertically up and down. The handle 11 extends to the outside through the middle cover 19. The part of the handle 11 extending to the outside can be used by the operator. Here, the handle 11 can rotate relative to the middle cover 19. The middle cover 19 is provided with a hole for the handle 11 to rotate, and the two sides of the hole also form the rotation limit of the handle 11.

[0047] Specifically, the base 20 is provided with a support member 201, which is a U-shaped structure, and the first shaft hole 14 is located in the support member 201. The arrangement of the support member 201 enables the base 20 to better cooperate with the handle 11 to form a relative rotation effect. Here, the support member 201 can be integrally formed with the base 20, or the support member 201 can be separated from the base 20, and the support member 201 forms a fixing effect with the base 20 through a buckle or other connection method.

[0048] Specifically, as attached Figure 7 As shown, the handle 11 is provided with a first plane portion 111, and the side surface of the support member 201 is located on the rotation track of the first plane portion 111, that is, when the handle 11 rotates, the first plane portion 111 will abut against the side surface of the support member 201, forming a limiting and fixing effect, further improving the limiting position of the handle 11, and facilitating subsequent assembly. In this embodiment, the first plane portion 111 cooperates with the support member 201 to form a dead point limiting position, so that the product moving contact 12 can remain parallel to the product base 20 when the handle 11 is closed, so that some parts can be installed smoothly.

[0049] Specifically, one of the handle 11 and the support member 201 is provided with a limiting column 21, and the other of the handle 11 and the support member 201 is provided with a limiting notch 22 that cooperates with the limiting column 21. The cooperation between the limiting column 21 and the limiting notch 22 also plays a role in limiting and fixing. When the handle 11 is provided with a limiting column 21, the support member 201 is provided with a limiting notch 22; conversely, when the handle 11 is provided with a limiting notch 22, the support member 201 is provided with a limiting column 21. In this embodiment, the handle 11 is provided with a limiting notch 22, the support member 201 is provided with a limiting column 21, and an extension column is provided in the middle position of the first planar portion 111, and the limiting notch 22 is located at the extension column. The limiting column 21 is located in the middle position of the U-shape.

[0050] Specifically, as attached Figure 2As shown, it also includes a moving contact 12, a static contact 13 and a reset member 17 accommodated in the accommodating cavity 100. The moving contact 12 and the static contact 13 are connected in series in the electrical circuit and can be located near the input end or near the output end. The number of groups of the moving contacts 12 and the static contacts 13 is consistent with the number of phase lines of the input end and the output end, that is, the two-phase electricity is two groups of moving contacts 12 and static contacts 13, forming the same opening and closing effect. In this embodiment, the moving contact 12 cooperates with the static contact 13 at the input end, and the other end of the moving contact 12 is electrically connected to the output end through a flexible conductive material such as soft copper wire or copper braided wire or wire. The static contact 13 is located on the motion trajectory of one end of the moving contact 12. When the handle 11 rotates, it will drive the moving contact 12 to move toward the static contact 13, thereby achieving the effect of connection. One end of the reset member 17 abuts against the accommodating cavity 100, and the other end of the reset member 17 abuts against the end of the moving contact 12 away from the static contact 13. The reset member 17 plays the role of energy storage and reset. When the handle 11 applies force to the moving contact 12, the reset member 17 compresses and stores energy. When the force disappears, the reset member 17 releases energy, so that the moving contact 12 is separated from the static contact 13, forming a disconnection effect. The handle 11 drives the moving contact 12 to move.

[0051] Specifically, the handle 11 is provided with a driving part 112, and the middle area is from the position where the reset member 17 abuts against the moving contact member 12 to the position where the moving contact member 12 and the static contact member 13 cooperate. The driving part 112 is provided to better achieve the driving effect of the moving contact member 12. Here, the driving part 112 can be a cam structure.

[0052] Specifically, the accommodating cavity 100 is provided with a fixing groove 101, and one end of the resetting member 17 is accommodated in the fixing groove 101. The provision of the fixing groove 101 makes it more convenient to install the resetting member 17.

[0053] Specifically, the fixing groove 101 is provided with a first fixing column 102, the movable contact member 12 is provided with a first positioning protrusion 121, one end of the reset member 17 is sleeved on the first fixing column 102, and the other end of the reset member 17 is sleeved on the first positioning protrusion 121. The cooperation between the first fixing column 102 and the first positioning protrusion 121 enables the reset member 17 to form a better fixing effect.

[0054] Specifically, the wiring holes at the input end are arranged downward, and the wiring holes at the output end are arranged forward. Those skilled in the art may also distribute the directions of the wiring holes according to actual needs.

[0055] Specifically, the moving contact 12, the stationary contact 13, the reset member 17, and the handle 11 are all located below the middle cover 19. The output end is located below the surface cover 18, so that the external wiring will not interfere with the relative positional relationship of the moving contact 12 and the reset member 17, and the wiring is more convenient.

[0056] Specifically, the installation steps are as follows: after the handle 11 , the moving contact 12 , the stationary contact 13 , the reset member 17 and the base 20 are matched to form a fixation, the middle cover 19 is then installed to achieve fixation, and finally the surface cover 18 is assembled.

[0057] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
