Description

Technical Field

[0001] The utility model belongs to the technical field of switch equipment, and in particular relates to a rotary switch for a lamp cap. Background Art

[0002] In the field of modern lighting, there are many types of lamps to meet different scenarios and functional requirements. However, the traditional mother-and-child lamp system, that is, multiple lamp heads are combined on a lamp body and controlled by a switch, has a series of inconveniences. The main problem is that the entire mother-and-child lamp system is controlled by a light switch, which brings inconvenience and limitations to users. For example, when one lamp is turned on, some of the lamps cannot be selectively turned off, resulting in limitations in function and control.

[0003] The main problem with traditional mother-and-child lamps is that they cannot achieve independent control of each lamp head. When the user wants to turn one of the lamp heads on or off, the entire mother-and-child lamp system can only be controlled by the overall switch. This is too rigid in some scenarios. For example, when the user only needs partial lighting, the traditional mother-and-child lamp system cannot meet the selective control needs of a single lamp head.

[0004] This is the main disadvantage of traditional technology. Utility Model Content

The operation is simple and the use is convenient.

[0023] During specific implementation, an arc-shaped first active position 111 is provided on the inner rear side of the mounting cavity 11, an arc-shaped second active position 112 is provided on the inner front side of the mounting cavity 11, a first contact end 21 is provided on one side of the rotating contact piece 20, the size of the first active position 111 is larger than the size of the first contact end 21, and the first contact end 21 can be movably set on the first active position 111, and a second contact end 22 is provided on the other side of the rotating contact piece 20, the size of the second active position 112 is larger than the size of the second contact end 22, and the second contact end 22 can be movably set on the second active position 112. During use, when the rotating contact piece 20 is rotated, the first contact end 21 can move along the first active position 111, and the second contact end 22 can move along the second active position 112.

[0024] During specific implementation, a first mounting position 113 is provided on the inner left side of the mounting cavity 11, and a second mounting position 114 is provided on the inner right side of the mounting cavity 11. The first conductive sheet 30 is arranged on the first mounting position 113, and the second conductive sheet 40 is arranged on the second mounting position 114. A first conductive end 31 is provided on the rear end of the first conductive sheet 30, and the first contact end 21 is arranged opposite to the first conductive end 31. A second conductive end 41 is provided on the side of the second conductive sheet 40, and the second contact end 22 is arranged opposite to the second conductive end 41. When in use, when the rotating contact sheet 20 is rotated, the first contact end 21 moves along the first active position 111 and contacts and conducts with the first conductive end 31, and the second contact end 22 moves along the second active position 112 and contacts and conducts with the second conductive end 41, thereby realizing contact and separation with the first conductive sheet 30 and the second conductive sheet 40, thereby controlling the on and off state of the power supply, which is convenient to use.

[0025] A connection point 115 communicating with the first installation position 113 is disposed on the left side of the installation cavity 11. The front end of the first conductive sheet 30 is disposed in the connection point 115. A wire clip 32 is provided at the front end of the first conductive sheet 30. When in use, the wire clip 32 is used to connect external wires.

[0026] A conductive position 116 connected to the second mounting position 114 is opened on the right side of the mounting cavity 11. A rivet interface 42 is provided at the front end of the second conductive sheet 40. The rivet interface 42 is arranged in the conductive position 116. When in use, the rivet interface 42 is used to connect the rivets, and then a conductive connection is established with the lamp holder through the rivets.

[0027] A rotating rod 50 is connected to the outer side of the rotating central axis 12, and rotating bayonet 51 is respectively recessed on the lower two sides of the rotating rod 50. The size of the rotating bayonet 51 is larger than the size of the first contact end 21 and the second contact end 22. The rotating bayonet 51 is respectively connected to the first contact end 21 and the second contact end 22. When in use, when it is necessary to rotate the rotating contact piece 20 for contact and conduction, the rotating contact piece 20 is driven to move in a circle by rotating the rotating rod 50, thereby achieving the effect of contact conduction or separation and power off, which is convenient to use.

[0028] The mounting bottom shell 10 is covered with a mounting cover 60, and a connecting column 61 is convexly provided at the lower end of the mounting cover 60.

The mounting cover 60 is used to prevent internal components from leaking out, which helps to protect the internal components of the switch and ensure that it remains safe and reliable during use.

[0029] Two positioning posts 63 are protruded from the lower end of the mounting cover 60 , and the two positioning posts 63 are respectively pressed on the first conductive sheet 30 and the second conductive sheet 40 , so that the mounting of the first conductive sheet 30 and the second conductive sheet 40 is more stable and firm.

[0030] When in use, the switch is electrically connected to the lamp holder. When turning on and off the power, the rotating rod 50 is rotated to drive the rotating contact piece 20 to move in a circle with the rotating central axis 12 as the center point, so that the two sides of the rotating contact piece 20 are respectively in contact with the first conductive piece 30 and the second conductive piece 40 for conductivity, thereby turning on the power; conversely, the rotating rod 50 is rotated in the opposite direction to drive the rotating contact piece 20 to separate from the first conductive piece 30 and the second conductive piece 40 respectively to cut off the power, thereby turning off the power. The operation is simple and easy to use. Moreover, the switch can be connected to the lamp holder separately, so that the switch of each lamp holder can be controlled separately, which solves the problem that the traditional mother-and-child lamp is composed of multiple lamp holders combined with a lamp body and the whole lamp switch is controlled by one switch, so that the user cannot control the switch of one lamp holder separately.

[0031] In summary, the bottom wall of the mounting base shell 10 is provided with a mounting cavity 11, a rotating central axis 12 is provided in the middle of the mounting cavity 11, a rotating contact piece 20 is provided on the outer bottom of the rotating central axis 12, and a first conductive piece 30 and a second conductive piece 40 are provided on both sides of the mounting cavity 11.

The rotary switch for the lamp holder of the utility model has a simple structure and is convenient for users to operate and use. It can be connected to each lamp holder separately to realize independent control of the switch of each lamp holder, thereby solving the limitations of traditional mother-and-child lamps.
