Description

Technical Field

[0001] The utility model relates to the technical field of socket switch control, in particular to a rotary socket switch and a socket. Background Art

[0002] Socket, also known as power socket, switch socket. Socket refers to a seat that has one or more circuit wirings that can be inserted, through which various wiring can be inserted.

[0003] This makes it easier to connect to other circuits. By connecting and disconnecting the line and the copper parts, the connection and disconnection of this part of the circuit can be achieved.

[0004] At present, the switch control of the socket module is basically a separate type, that is, the switch and the socket are separated, and the switch controls the socket through internal wiring. For example, the Chinese patent "Switch Socket" with application number CN202110221843.4 discloses: the switch assembly (1) includes a switch housing (11), a button (12) and a conductive element (13), a part of the button (12) is located inside the switch housing (11), and the other part is located outside the switch housing (11), and the conductive element (13) is located inside the switch housing (11) and contacts a part of the button (12). By additionally setting a switch button to control the power input of the socket, there are problems such as high cost, large size, and poor consumer experience.

[0005] To address this issue, a rotary switch socket has been developed. Chinese Patent Application No. CN202110221843.4, titled "A Rotary Switch Socket," discloses that the rotating live and neutral copper plates rotate to separate from or contact the fixed live and neutral copper plates, respectively, creating two power-on and power-off switching modes. This switch control method, relying on the rotation of the live and neutral copper plates, is prone to sparking during rotation control, and the copper plate wiring connections can easily loosen due to rotation, posing a significant safety hazard. Utility Model Content

[0011] This solution uses the pendulum spring as the power core to continuously provide a pressing force to the conductive component, so that the conductive component always maintains a stable contact relationship with the receiving component; at the same time, a spring cap is added as a positioning and installation structure, and a first limit block and a second limit block that cooperate with each other are designed. Combined with a through-type installation method, the pendulum spring can be quickly installed and work stably, effectively reducing the difficulty of product assembly and improving production efficiency.

[0012] In a further embodiment, the front end of the spring cap is recessed inward to form a cylindrical spring fixing position, and an upwardly protruding fixing column is provided in the middle of the spring fixing position, and the pendulum spring is nested on the fixing column.

[0013] This solution sets a cocentric spring fixing position and a fixing column on the front end surface of the spring cap, and uses the upward protruding fixing column to sleeve the pendulum spring; combined with the cylindrical spring fixing position to surround the pendulum spring, the stability of the pendulum spring connection is ensured.

[0014] In a further embodiment, the first limiting block is configured as an outwardly protruding ear structure, and the second limiting block is configured as an outwardly protruding brim structure.

[0020] After the mounting buckle is embedded in the power receiving component, the inclined surface abuts against the surface of the power receiving component under the action of the swing leaf spring.

[0021] The switch pendulum of this solution has two sides of the front end that shrink toward the middle to form an inclined surface that abuts the power receiving part. The inclined surface can better adapt to the swinging movement with the conductive end as the center, thereby optimizing the switch rotation experience; an outward-protruding mounting buckle is added to the inclined surface, and the mounting buckle is engaged with the power receiving part to form a rotating axis, so that the switch pendulum always rotates along this axis, and the conductive connection part is stable and reliable. By achieving stable circuit connection of the conductive part of the switch, the safety and reliability of the socket are achieved.

One side wall of the housing serves as a mounting wall 41, and a through-mounting hole 42 is provided on the mounting wall 41.
