Description

Technical Field

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

[0002] Rocker switches are commonly used as power switches for electronic devices. Generally, they are composed of a housing, a rocker button, and rocker contact pieces. The rocker button and the rocker contact pieces can be rotatably arranged in the accommodating cavity of the housing respectively. When the two ends of the rocker button are pressed down respectively, the bottom of the rocker button moves along the rocker contact piece, causing the rocker contact piece to swing back and forth around the supporting part to achieve the on or off function.

[0003] Indicator lights for indicating the on / off state are usually installed inside rocker switches. For example, Chinese Utility Model Patent CN214226800 U discloses a rocker switch. In this solution, the neutral terminal is electrically connected to the circuit board through a conductive elastic sheet. When the rocker button is pressed, the conductive elastic sheet contacts the contact point on the lower surface of the PCB board to light up the LED lamp, playing the role of power-on indication. However, in this solution, the fixed connection method between the neutral terminal and the conductive elastic sheet is spot welding or riveting, and the conductive elastic sheet cannot be replaced separately. If the conductive elastic sheet fails, the entire neutral terminal needs to be replaced, resulting in a relatively high use and maintenance cost. Utility Model Content

[0004] In view of this, the present utility model provides a rocker switch with a power-on indicator light to solve the problem in the prior art that when the conductive elastic sheet fails, the entire neutral terminal needs to be replaced, resulting in a relatively high use and maintenance cost.

[0005] The rocker switch with a power-on indicator light provided by the present utility model includes a base and a rocker button rotatably arranged with the base. The base has a live wire pin, a middle pin, and a neutral wire pin. One end of the live wire pin extending into the base is provided with a static contact. An indicator light is arranged inside the rocker button. A rocker contact piece is also arranged inside the base. A moving contact for contacting or disconnecting from the static contact is arranged on the rocker contact piece.

[0006] A pluggable and detachable conductive elastic sheet is arranged on the neutral wire pin. A conductive lamp socket is arranged on the bottom surface of the rocker button facing the neutral wire pin. The positive pole of the indicator light is electrically connected to the middle pin, and the negative pole of the indicator light is electrically connected to the conductive lamp socket. By operating the rocker contact piece through the rocker button, the moving contact is connected or disconnected from the static contact. At the same time, the conductive lamp socket contacts or separates from the conductive elastic sheet.

[0007] The upper end of the neutral pin is provided with a pin. The conductive elastic sheet has a back plate. The two 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 conductive lamp socket.

[0008] For the above rocker switch with a power-on indicator light, the conductive elastic sheet and the neutral 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 being easy to replace.

[0009] In the above technical solution, preferably, the rocker contact piece is U-shaped. The top of one side extends horizontally, and the moving contact is arranged at the end. The static contact is arranged opposite to the moving contact.

[0010] In the above technical solution, preferably, the intermediate 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.

[0011] In the above technical solution, preferably, a first boss is provided in the middle of the bottom surface of the rocker button, and a second boss is provided in the middle of the top surface of the rocker contact piece. One end of the spring is sleeved on the first boss, and the other end is sleeved on the second boss.

[0012] In the above technical solution, preferably, the first boss is cylindrical and the second boss is hemispherical.

[0013] In the above technical solution, preferably, the width of the pin is smaller than the width of the upper part of the neutral pin, and a chamfer is provided at the top of the pin.

[0014] In the above technical solution, preferably, a lamp window is provided on one side of the top surface of the rocker button for transmitting the light of the indicator light.

[0015] As can be seen from the above technical solution, the rocker switch with a power-on indicator light provided by the present invention solves the problem that in the prior art, the conductive elastic sheet and the neutral terminal adopt a fixed connection method of spot welding or riveting, and the conductive elastic sheet cannot be replaced separately, resulting in a relatively high use and maintenance cost. Compared with the prior art, the present invention has the following beneficial effects:

[0016] The conductive elastic sheet and the neutral pin adopt a pluggable and detachable connection method. Among them, the upper end of the neutral pin is provided with a pin. The conductive elastic sheet has a back plate. The two 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 conductive lamp socket. When the conductive elastic sheet fails, it can be conveniently replaced separately, reducing the maintenance cost and being easy to replace. Description of the Drawings

[0030] Next, in combination with the accompanying drawings of the embodiments of the present utility model, the technical solutions of the embodiments of the present utility model will be clearly and completely described. Obviously, the following described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present utility model.

[0031] 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.

[0032] 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 benchmark object of the product's use state. Obviously, the use of the corresponding orientation words does not limit the protection scope of this solution.

[0033] As Figure 1 、 Figure 2 、 Figure 3 shown, a rocker switch with a power-on indicator provided by the present utility model includes a base 10 and a rocker button 20 rotatably arranged with the base 10. A rocker contact 30 is further provided in the base 10. The rocker contact 30 is U-shaped, and the top of one side extends horizontally and a moving contact 31 is provided at the end.

[0034] 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 a static contact 14 is provided at one end extending into the base 10. 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.

[0035] The middle pin 12 is used to connect the load. The middle pin 12 extends into the base 10 and is supported on the bottom surface of the U-shaped part 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.

[0036] An indicator 21 is provided in the rocker button 20. A lamp window 22 is provided on one side of the top surface of the rocker button 20 for transmitting the light of the indicator 21. A conductive lamp socket 23 is provided on the bottom surface of the rocker button 20 facing the neutral wire pin 13. The positive pole of the indicator 21 is electrically connected to the middle pin 12, and the negative pole of the indicator 21 is electrically connected to the conductive lamp socket 23 for forming a power supply loop. In the present utility model, the indicator 21 can adopt a neon lamp or an LED lamp.

[0037] In the middle of the bottom surface of the rocker button 20, there is a first boss 24. In the middle of the top surface of the bottom wall of the U-shaped groove of the rocker contact piece 30, there is a second boss 32. One end of the spring 50 is sleeved on the first boss 24, and the other end is sleeved on the second boss 32. By operating the rocker button 20, the rocker contact piece 30 can be actuated to connect or disconnect the moving contact 31 and the static contact 14. At the same time, the conductive elastic piece 40 is connected or disconnected from the conductive lamp socket 23.

[0038] In this embodiment, the first boss 24 is cylindrical, and the second boss is hemispherical to facilitate processing and manufacturing.

[0039] In the present utility model, the conductive elastic piece 40 and the neutral wire pin 13 adopt a pluggable and detachable connection method. When the conductive elastic piece 40 fails, it can be conveniently replaced separately, reducing the maintenance cost and being easy to replace.

[0040] As Figure 4 、 Figure 5 shown, at the upper end of the neutral wire pin 13, there is a pin 131. The width of the pin 131 is smaller than the width of the neutral wire pin 13. At the top of the pin 131, there is a chamfer to facilitate the insertion of the conductive elastic piece 40.

[0041] The conductive elastic piece 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 upward obliquely to form an elastic contact piece 43 for elastically contacting the conductive lamp socket 23.

[0042] In the solution of the present utility model, when the rocker button 20 is pressed towards the first end, through the spring 50, the moving contact 31 on the rocker contact piece 30 contacts the static contact 14, the rocker switch is turned on, and the load is powered on; at the same time, the conductive elastic piece 40 contacts the conductive lamp socket 23, the indicator lamp 21 is connected to the power supply, and the indicator lamp 21 lights up, indicating that the rocker switch is currently in the on state.

[0043] When the rocker button 20 is pressed towards the second end, through the spring 50, the moving contact 31 on the rocker contact piece 30 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 piece 40 is separated from the conductive lamp socket 23, the indicator lamp 21 is disconnected from the power supply, and the indicator lamp 21 is turned off, indicating that the rocker switch is currently in the off state.

[0044] Based on the description of the above specific embodiments, compared with the prior art, the rocker switch with a power-on indicator lamp provided by the present utility model has the following advantages:

[0045] First, 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. Moreover, the plug-in structure makes the replacement very convenient.

[0046] Second, in the solution of this application, a first boss is provided in the middle of the bottom surface of the rocker button, and a second boss is provided in the middle of the top surface of the rocker contact piece. One end of the spring is sleeved on the first boss, and the other end is sleeved on the second boss, which is equivalent to a flexible rod structure. The rocker button operating the rocker contact piece has a better feel and high operating reliability.

[0047] Third, in the solution of this application, the rocker contact piece is U-shaped. The top of one side extends horizontally and a moving contact is provided at the end. The middle pin extends into the base and is supported on the bottom surface of the U-shaped part of the rocker contact piece, forming a rocker structure for the rocker contact piece. Cooperating with the spring to operate the rocker contact piece, the operating reliability is high.

[0048] 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 more limitations, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0049] The utility model is not limited to the above best embodiment. Anyone should know that structural changes made under the inspiration of the utility model, as long as they have the same or similar technical solutions as the utility model, all fall within the protection scope of the utility model.
