Description

Technical Field

[0001] This application relates to the technical field of switches, and particularly to a round rocker switch with an indicator light. Background Art

[0002] Rocker switches usually have indicator lights built in for indicating the powered-on state. Although LED lights are small in size and long in service life, neon lights still have a wide range of applications because they do not require a circuit board for DC conversion.

[0003] Currently, the rocker switches using neon lights as indicator lights have the following problems:

[0004] First, the neon light is directly placed on the rocker button without reliable positioning, and the neon light is prone to movement, causing the wire to break.

[0005] Second, a conductive block is provided on the support frame of the rocker button. The negative lead of the neon light is connected to the conductive block. A conductive elastic sheet is fixedly provided at the upper end of the neutral wire pin on the base, and the conductive elastic sheet contacts or disconnects from the conductive block. Among them, on the one hand, using the conductive block as a connecting part makes the structure complex; on the other hand, the spot welding or riveting fixed connection method is adopted between the neutral wire terminal and the conductive elastic sheet, and the conductive elastic sheet cannot be replaced separately. If the conductive elastic sheet fails, the entire neutral wire terminal needs to be replaced, resulting in a relatively high use and maintenance cost. Summary of the Utility Model

[0006] In view of this, the present utility model provides a round rocker switch with an indicator light to solve the problems in the prior art that the neon light has no reliable positioning, the electrical connection structure of the neon light is complex, and if the conductive elastic sheet fails, the entire neutral wire terminal needs to be replaced, resulting in a relatively high use and maintenance cost.

[0007] The round rocker switch with an indicator light provided by the present utility model includes a base and a round rocker button rotatably arranged with the base. The base has a live wire pin, an intermediate pin, and a neutral wire pin. One end of the live wire pin extending into the base is provided with a static contact. A rocker contact piece is also provided in the base, and a moving contact for contacting or disconnecting from the static contact is provided on the rocker contact piece. The rocker button includes:

[0008] An upper cover, the side of which is provided with a rotating shaft for rotatably connecting with the base;

[0009] The support frame is installed in the upper cover from bottom to top. There is a strip-shaped concave pit in the support frame. One end of the strip-shaped concave pit is provided with a first through hole, and the other end of the strip-shaped concave pit is provided with a second through hole. A cross beam is arranged in the second through hole, and the bottom surface of the cross beam is flush with the bottom surface of the support frame; a first boss is arranged at the center of the bottom surface of the support frame. The first boss is provided with an inner hole, and a metal sliding sleeve is arranged in the inner hole. A spring is arranged between the metal sliding sleeve and the inner hole, so that the metal sliding sleeve elastically abuts against the top surface of the rocker contact piece;

[0010] The indicator light is arranged in the strip-shaped concave pit. The positive lead of the indicator light passes through the first through hole and is electrically connected to the spring, and is electrically connected to the rocker contact piece through the spring and the metal sliding sleeve. The negative lead of the indicator light is wound around the cross beam in series with a current-limiting resistor. The upper end of the zero-line pin is provided with a pin, and a conductive elastic piece is inserted on the pin. The conductive elastic piece can contact or disconnect from the negative lead wound around the cross beam to light up or extinguish the indicator light.

[0011] For the above-mentioned round rocker switch with an indicator light, the indicator light is arranged in the strip-shaped concave pit of the support frame to limit the indicator light, which can avoid the movement of the indicator light, thereby avoiding the disconnection of the lead of the indicator light due to pulling. Among them, one end of the strip-shaped concave pit is provided with a first through hole, the other end of the strip-shaped concave pit is provided with a second through hole, a cross beam is arranged in the second through hole, the positive lead of the indicator light passes through the first through hole and is electrically connected to the rocker contact piece, and the negative lead of the indicator light is wound around the cross beam in series with a current-limiting resistor. The conductive elastic piece can contact or disconnect from the negative lead wound around the cross beam to light up or extinguish the indicator light. The conductive connection structure of the indicator light no longer needs to be provided with a conductive block, and the structure is simple and the conduction is reliable.

[0012] In the above technical solution, preferably, the upper end of the zero-line pin is provided with a pin. The conductive elastic piece has a back plate, and both side edges of the back plate are bent to form a U-shaped slide rail. The pin is inserted into the U-shaped slide rail. The upper end of the back plate extends obliquely upward to form an elastic contact piece for elastically contacting the negative lead wound around the cross beam. The conductive elastic piece and the zero-line pin adopt a pluggable and detachable connection method. When the conductive elastic piece fails, it can be conveniently replaced separately, reducing the maintenance cost and being convenient for replacement.

[0013] In the above technical solution, preferably, the rocker contact piece is an arc-shaped sheet structure, which is convenient for operating the rocker contact piece.

[0014] In the above technical solution, preferably, the middle pin extends into the base and supports on the bottom surface of the U-shaped part of the rocker contact piece, so that the rocker contact piece forms a rocker structure. The structure is simple and the operation is reliable.

[0015] In the above technical solution, preferably, the upper cover is made of a translucent material.

[0016] In the above technical solution, preferably, the second through hole communicates with the side wall of the support frame to form a notch, so as to facilitate coiling the negative lead of the indicator light.

[0017] As can be seen from the above technical solution, the circular rocker switch with an indicator light provided by the present utility model solves the problems in the prior art that the neon lamp has no reliable positioning and the electrical connection of the neon lamp requires the setting of a conductive block, resulting in a complex structure. Compared with the prior art, the present utility model has the following beneficial effects:

[0018] A strip-shaped concave pit is provided inside the support frame. One end of the strip-shaped concave pit is provided with a first through hole, and the other end of the strip-shaped concave pit is provided with a second through hole. A cross beam is provided in the second through hole. The indicator light is arranged in the strip-shaped concave pit. The positive lead of the indicator light passes through the first through hole and is electrically connected to the spring, and is electrically connected to the rocker contact through the spring and the metal sliding sleeve. The negative lead of the indicator light is coiled around the cross beam after being connected in series with a current-limiting resistor. There is no need to set a conductive block, which simplifies the conductive connection structure and improves reliability. Description of the Drawings

[0038] In order to more clearly explain and illustrate the technical solutions and implementation manners of the present utility model, several preferred specific embodiments for implementing the technical solutions of the present utility model are introduced below.

[0039] It should be noted that the orientation words such as "inside, outside", "front, back" and "left, right" in this article are expressed based on the product in the use state. Obviously, the use of the corresponding orientation words does not constitute a limitation to the protection scope of this solution.

[0040] Such as Figure 1 , Figure 2 ,Figure 3 , Figure 4 As shown, a circular rocker switch with an indicator light provided by the present utility model includes a base 10 and a circular rocker button 20 rotatably arranged on the side wall of the base 10. A rocker contact 30 is further provided in the base 10. The rocker contact 30 is an arc-shaped sheet structure, and one end is provided with a moving contact 31.

[0041] The base 10 has a live wire pin 11, a middle pin 12 and a neutral wire pin 13. The live wire pin 11 is used to connect the live wire, and one end extending into the base 10 is provided with a static contact 14. The static contact 14 is arranged opposite to the moving contact 31. The rocker contact 30 can be operated by the rocker button 20 to connect or disconnect the moving contact 31 and the static contact 14.

[0042] The middle pin 12 is used to connect the load. The middle pin 12 extends into the base 10 and supports on the bottom surface of the rocker contact 30, so that the rocker contact 30 forms a rocker structure. The neutral wire pin 13 is used to connect the neutral wire, and a conductive elastic sheet 40 is inserted and connected to the upper end of the neutral wire pin 13.

[0043] The rocker button 20 includes a support frame 21 and an upper cover 22. The support frame 21 is embedded in the upper cover 22 from bottom to top. The upper cover 22 is made of a translucent material. Rotating shafts are respectively provided on both side surfaces of the upper cover 22 for rotatably connecting with the side wall of the base 10 to form a rocker button structure.

[0044] As Figure 5 , Figure 6 shown, a strip-shaped concave pit 211 is provided in the support frame 21. A first through hole 212 is provided at one end of the strip-shaped concave pit 211, and a second through hole 213 is provided at the other end of the strip-shaped concave pit 211. A cross beam 214 is provided in the second through hole 213. The bottom surface of the cross beam 214 is flush with the bottom surface of the support frame 21. A first boss 215 is provided at the center of the bottom surface of the support frame 21. In this embodiment, the first through hole 212 and the second through hole 213 are rectangular holes.

[0045] The first boss 215 is provided with an inner hole, and a metal sliding sleeve 216 is provided in the inner hole. The lower end of the metal sliding sleeve 216 is hemispherical. A spring 217 is provided between the metal sliding sleeve 216 and the inner hole, so that the metal sliding sleeve 216 elastically abuts against the top surface of the rocker contact 30 for operating the rocker contact 30 to connect or disconnect with the static contact 14.

[0046] The indicator light 23 is arranged in the strip-shaped concave pit 211 to limit the indicator light 23 and prevent it from moving, thereby avoiding the disconnection of the lead wire of the indicator light 23 due to pulling. The positive lead wire 231 of the indicator light 23 passes through the first through hole 212 and is electrically connected to the spring 217, and is electrically connected to the rocker contact 30 through the spring 217 and the metal sliding sleeve 216. The negative lead wire 232 of the indicator light 23 is wound around the cross beam 214 after being in series with a current-limiting resistor. The conductive elastic sheet 40 can contact or disconnect from the negative lead wire wound around the cross beam 214 to turn on or off the indicator light 23.

[0047] The second through hole 213 communicates with the side wall of the support frame 21 to form a notch, so as to facilitate the winding of the negative lead wire 232 of the indicator light 23.

[0048] In the present utility model, the conductive elastic sheet 40 and the zero-line pin 13 adopt a pluggable and detachable connection method. When the conductive elastic sheet 40 fails, it can be conveniently replaced separately, reducing the maintenance cost and being easy to replace.

[0049] As Figure 7 、 Figure 8 shown, the upper end of the zero-line pin 13 is provided with a pin 131. The width of the pin 131 is smaller than the width of the zero-line pin 13, and the top of the pin 131 is provided with a chamfer to facilitate the insertion of the conductive elastic sheet 40.

[0050] The conductive elastic sheet 40 has a back plate 41. The two side edges of the back plate 41 are bent to form a U-shaped slide rail 42. The pin 131 is inserted into the U-shaped slide rail 42. The upper end of the back plate 41 extends obliquely upward to form an elastic contact piece 43 for elastically contacting the negative lead wire wound around the cross beam 214.

[0051] As Figure 3 shown, in the solution of the present utility model, when the rocker button 20 is pressed towards the first end, the rocker contact 30 is pressed through the metal sliding sleeve 216, so that the moving contact 31 contacts the static contact 14, the rocker switch is turned on, and the load is powered on; at the same time, the conductive elastic sheet 40 contacts the negative lead wire wound around the cross beam 214, the indicator light 23 is connected to the power supply, and the indicator light 23 is turned on to indicate that the rocker switch is currently in the powered-on state.

[0052] As Figure 4 shown, when the rocker button 20 is pressed towards the second end, the rocker contact 30 is pressed through the metal sliding sleeve 216, the moving contact 31 is separated from the static contact 14, the rocker switch is turned off, and the load is powered off; at the same time, the conductive elastic sheet 40 is separated from the negative lead wire wound around the cross beam 214, the indicator light 23 is disconnected from the power supply, and the indicator light 23 is turned off to indicate that the rocker switch is currently in the off state.

[0053] Based on the descriptions of the above specific embodiments, the round rocker switch with an indicator light provided by the present utility model has the following advantages compared with the prior art:

[0054] First, a strip-shaped concave pit is provided inside the support frame. One end of the strip-shaped concave pit is provided with a first through hole, and the other end of the strip-shaped concave pit is provided with a second through hole. A cross beam is provided inside the second through hole. The indicator light is arranged inside the strip-shaped concave pit to limit the indicator light and prevent the indicator light from moving, thereby avoiding the disconnection of the lead wire of the indicator light due to pulling.

[0055] Second, the positive lead wire of the indicator light passes through the first through hole and is electrically connected to the rocker contact. The negative lead wire of the indicator light is wound around the cross beam after being connected in series with a current-limiting resistor. The conductive elastic sheet can contact or disconnect from the negative lead wire wound around the cross beam to light up or extinguish the indicator light. The conductive connection structure of the indicator light does not require the setting of a conductive block, has a simple structure, and is electrically conductive and reliable.

[0056] Third, different from the fixed connection between the conductive elastic sheet and the zero-line pin in the traditional design, in this application, the conductive elastic sheet and the zero-line pin adopt a pluggable and detachable connection method. When the conductive elastic sheet fails, it can be conveniently replaced separately, reducing the maintenance cost, and the plug-in structure is very convenient to replace.

[0057] Finally, it should also be noted that the terms "including", "comprising" or any other variant thereof used in this text are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitations, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0058] The present utility model is not limited to the above best implementation manner. Anyone should know that structural changes made under the inspiration of the present utility model, as long as they have the same or similar technical solutions as the present utility model, all fall within the protection scope of the present utility model.
