[0002] A circuit breaker refers to a switching device that can close, carry, and break the current under normal circuit conditions and can also close, carry, and break the current under abnormal circuit conditions within a specified time. Existing circuit breakers usually obtain power by connecting the control mechanism to the live terminal and the neutral terminal through wires. However, connecting through wires requires a set of processes such as wire cutting, wire stripping, and soldering during production, which takes a relatively long time. Content of the Utility Model

Detailed implementation manners
[0014] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the accompanying drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.
[0015] As Figure 1As shown in the figure, a structure for obtaining power from a circuit breaker includes a control board, a socket strip, a live wire power-taking component, a live wire connecting component, a neutral wire power-taking component, and a neutral wire connecting component. The socket strip is arranged on the control board. The first end of the live wire power-taking component is arranged at the live wire port of the socket strip. The second end of the live wire power-taking component abuts against the first end of the live wire connecting component. The second end of the live wire connecting component is arranged in the live wire terminal and is used to cooperate with the live wire terminal to clamp the live wire. The first end of the neutral wire power-taking component is arranged at the neutral wire port of the socket strip. The second end of the neutral wire power-taking component abuts against the first end of the neutral wire connecting component. The second end of the neutral wire connecting component is arranged in the neutral wire terminal and is used to cooperate with the neutral wire terminal to clamp the neutral wire. The structure of this application is mainly applied to 1P+N circuit breakers. 1P+N circuit breakers are usually used to disconnect the live wire. The tripping mechanism and the control board are also arranged on the live wire side. The neutral wire circuit usually will not be disconnected. The live wire of the power supply of the control board takes power at the live wire terminal through the live wire power-taking component and the live wire connecting component, and the neutral wire takes power at the neutral wire terminal through the neutral wire power-taking component and the neutral wire connecting component. Its power-taking structure replaces the original wire connection method through structural design. Such a power-taking structure can save the production cost and assembly time at the production end, and at the same time make the power-taking of the circuit breaker more reliable.
[0016] The neutral wire power-taking component includes a neutral wire insertion section, a neutral wire connection section, and a neutral wire elastic section connected in sequence. The neutral wire connecting component includes a neutral wire clamping section and a neutral wire abutting section connected to each other. The neutral wire terminal includes a bolt and a loop. A bolt hole for connecting the bolt is opened above the loop. The neutral wire insertion section is arranged at the neutral wire port of the socket strip. The neutral wire elastic section abuts against the neutral wire abutting section. The neutral wire clamping section is arranged in the loop. The bolt is used to drive the loop to move upward, so that the loop and the neutral wire clamping section cooperate to clamp the neutral wire. The bolt and the loop of the neutral wire terminal are designed as existing designs. The bolt is usually fixed in the shell and cannot move. The bolt rotates to drive the loop to move up and down, so as to clamp the live wire or the neutral wire. The socket strip is an existing design. The neutral wire insertion end is designed to be a column shape that can be inserted into the socket strip. The neutral wire connection section is used to connect the neutral wire elastic section, and its length depends on the distance between the socket strip and the live wire terminal.
[0017] The neutral wire elastic section is spiral. When the spiral neutral wire elastic section abuts against the neutral wire abutting section, it can generate a certain elastic force, so as to keep the neutral wire elastic section and the neutral wire abutting section always in contact.
[0018] The neutral wire abutting section can be designed into the following two structures. The two embodiments can be jointly arranged in a circuit breaker.
[0019] Embodiment 1: As Figure 2 shown, the surface of the neutral wire abutting section facing the neutral wire elastic section is a plane, and the plane of the neutral wire elastic section abuts against the neutral wire abutting section. The neutral wire elastic section abuts against the plane of the neutral wire abutting section, so as to prevent the neutral wire elastic section from slipping, so that the neutral wire power-taking component and the neutral wire connecting component can always maintain a good connection relationship and ensure power supply.
[0020] Embodiment 2: As Figure 3 shown, a protrusion extends from the side of the neutral wire contact section facing the neutral wire elastic section, and the spiral center of the neutral wire elastic section is sleeved on the protrusion. The spiral center of the neutral wire elastic section is hollow, and a protrusion that is stuck inside the spiral center extends from the side of the neutral wire contact section facing the neutral wire elastic section, which can prevent the displacement of the neutral wire elastic section, so that the neutral wire power-taking component and the neutral wire connecting component can always maintain a good connection relationship to ensure power supply.
[0021] As Figure 4 and 5 shown, the live wire power-taking component includes a live wire insertion section, a live wire connection section, and a live wire elastic section that are connected in sequence. The live wire connecting component includes a live wire clamping section and a live wire contact section that are connected to each other. The live wire terminal includes a bolt and a loop. A bolt hole for connecting the bolt is opened above the loop. The live wire insertion section is arranged at the live wire port of the socket. The live wire elastic section and the live wire contact section are in contact with each other. The live wire clamping section is arranged inside the loop. The bolt is used to drive the loop to move upward, so that the loop and the live wire clamping section cooperate to clamp the live wire.
[0022] The live wire elastic section is flat, and the included angle between the live wire elastic section and the live wire connection section is an obtuse angle. The side of the live wire contact section facing the live wire elastic section is a plane, which is used to contact the live wire elastic section, so that the included angle between the live wire elastic section and the live wire connection section is smaller than the included angle when the live wire elastic section and the live wire connection section are static. Both the live wire power-taking component and the live wire connecting component are made of electrically conductive materials, such as metal materials such as copper, tin, or alloys. The live wire power-taking component has a certain elastic recovery performance. After the live wire elastic section and the live wire contact section are in contact, the included angle becomes smaller, so that the live wire elastic section generates a certain elastic contact with the live wire connection section to ensure the connection between the live wire power-taking component and the live wire connecting component.
[0023] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
