Description

Technical Field

[0001] The utility model belongs to the technical field of circuit breakers, in particular to a circuit breaker for preventing electric shock. Background Art

[0002] A circuit breaker is a switching device that can close, carry and interrupt current under normal circuit conditions and can close, carry and interrupt current under abnormal circuit conditions within a specified time.

[0003] However, when the existing circuit breaker is used, if there is no anti-electric shock mechanism at the contact point between the circuit breaker and the wire, once the body part comes into contact with the connected wire during use, it may cause a safety accident to a certain extent, affecting the safety performance of its use. Therefore, an anti-electric shock circuit breaker is needed. Although the traditional anti-electric shock circuit breaker has anti-electric shock protection, the wire is still in the same vertical upward direction as the force direction, and it is easy to be broken when subjected to external force.

[0004] After searching, the Chinese patent document (authorization announcement number CN218887093U) is a circuit breaker that prevents electric shock. Under the action of the cap, it achieves an insulation protection effect when the connecting groove and the connecting wire are in contact. Through the connection of the protective plate and the cap, under the action of the protective plate, the protection range of the connecting wire against electric shock is improved. Under the connection of the slider and the tension spring, the elastic adjustment of the position of the pressure plate in the control frame is achieved, and the pressure plate is fixed to the position of the connecting belt in the control frame, thereby achieving the control of the effective length of the connecting belt on the protective plate, and achieving the restraining effect of the position of the wire on the protective plate. This patent has the function of preventing electric shock of the circuit breaker, but the wire is still in the same vertical upward direction as the force direction, and it is easy to be broken when subjected to external force. Utility Model Content

[0005] The utility model aims to provide a circuit breaker for preventing electric shock, so as to solve the problems raised in the background technology.

[0006] To achieve the above object, the utility model provides the following technical solutions: an anti-electric shock circuit breaker, comprising a housing for constituting the circuit breaker, the bottom end of the housing is configured with a wire hole for placing wires, the side of the housing is configured with a threaded hole connected to the wire hole, the threaded hole is threadedly connected with a bolt for fixing the wire, and the side of the housing is rotatably connected with a protective shell for blocking the bolt and playing an anti-electric shock function;

[0007] The bottom end of the shell is connected with a limit frame corresponding to the position of the wire hole, which plays the role of preventing electric shock and protecting the wires. The inner cavity of the limit frame is provided with a limit plate for fixing the wires. The inner wall of the limit frame and the side of the limit plate are bonded with rubber pads with elastic and insulating functions. The bottom end of the limit frame is welded with a connecting plate, which is rotatably connected to an L-shaped steering plate for steering the wires.

[0008] As a preferred embodiment, a threaded rod is rotatably connected to the side surface of the limiting plate via a bearing, and a threaded hole adapted to the threaded rod is provided on the side surface of the limiting frame.

[0009] As a preferred embodiment, the side surface of the limit frame is also connected to an inverted U-shaped protection plate corresponding to the position of the steering plate.

[0010] As a preferred embodiment, the inner wall of the protection plate and the outer side of the deflection plate are also bonded with rubber pads.

[0011] As a preferred embodiment, the side surfaces of the protective shell and the side surfaces of the steering plate are both connected with lock buckles for fixing.

[0012] As a preferred embodiment, the material of the protective shell is set to be transparent plastic.

[0013] As a preferred embodiment, a sealing gasket made of rubber material is bonded to the side of the protective shell.

[0014] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0015] The circuit breaker for preventing electric shock benefits from the design of the limit plate and the steering plate. The rotation of the threaded rod drives the limit plate to move, thereby fixing the wires and further improving the stability of the wires. The design of the steering plate changes the vertical laying of the wires in the prior art to a flipped Z-shaped laying, so that the movement of the wires is limited when they are subjected to force, thereby improving the stability of the wires.

[0016] Thanks to the design of the protective shell and the limit frame, the protective shell can protect the bolts and threaded holes from above to avoid direct contact with people and prevent electric shock. The limit frame protects and blocks the wire holes from below. The two work together to achieve comprehensive protection.

[0017] This anti-electric shock circuit breaker can not only improve the stability of the wires, but also provide comprehensive protection. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example

[0028] In order to change the orientation and direction of the wire, such as Figures 1 to 3The circuit breaker for preventing electric shock shown in the figure comprises a shell 1 for constituting the circuit breaker. The shape and size of the shell 1 are selected according to actual needs and are not subject to the figure. The bottom end of the shell 1 is configured with a wire hole for placing the wire. The side of the shell 1 is configured with a threaded hole connected to the wire hole. The threaded hole is threadedly connected with a bolt 2 for fixing the wire. The shell 1 is installed at a specified position. When the instrument is closed, the wire is passed through a limit frame 4 and placed in the wire hole. Then, the bolt 2 is rotated to fix the wire. The side of the shell 1 is rotatably connected with a protective shell 3 for blocking the bolt 2 and having an anti-electric shock function. The bottom end of the shell 1 is connected with a limit frame corresponding to the position of the wire hole and having the functions of preventing electric shock and protecting the wire. 4. The inner cavity of the limit frame 4 is provided with a limit plate 5 for fixing the wires. The inner wall of the limit frame 4 and the side of the limit plate 5 are bonded with rubber pads with elastic and insulating functions. A connecting plate 6 is welded at the bottom end of the limit frame 4. The connecting plate 6 is rotatably connected with an L-shaped steering plate 7 for steering the wires. The threaded rod 8 is rotated to drive the limit plate 5 to move, so that the limit plate 5 cooperates with the limit frame 4 to fix the wires, and the steering plate 7 is rotated. The protective plate 9 and the steering plate 7 are fixed by a lock, and the internal rubber pad is used to clamp the wires. The design of the L-shaped steering plate 7 changes the vertical laying of the wires in the prior art to a flipped Z-shaped one, so that the movement of the wires is restricted when they are subjected to force, thereby improving the stability of the wires.

[0029] In order to fix the wires and adapt to wires of different sizes, the side of the limiting plate 5 is rotatably connected to a threaded rod 8 through a bearing, and the side of the limiting frame 4 is provided with a threaded hole adapted to the threaded rod 8. Rotating the threaded rod 8 drives the limiting plate 5 to move, so that the limiting plate 5 cooperates with the limiting frame 4 to fix the wires.

[0030] For protection, the side of the limit frame 4 is also connected to an inverted U-shaped protection plate 9 corresponding to the position of the steering plate 7. The inner wall of the protection plate 9 and the outer side of the steering plate 7 are also bonded with rubber pads, and the internal rubber pads are used to clamp the wires.

[0031] The side surfaces of the protective shell 3 and the side surfaces of the steering plate 7 are both connected with lock buckles for fixing. The protective shell 3 is covered and the lock buckles are closed for fixing.

[0032] The material of the protective shell 3 is set to transparent plastic, and the visible design is convenient for staff to observe from the outside. A rubber sealing gasket is bonded to the side of the protective shell 3 to improve the sealing between the protective shell 3 and the outer shell 1 and prevent external factors such as water vapor from affecting the bolt 2.

[0033] How it works

[0034] The circuit breaker for preventing electric shock has the shell 1 installed at a specified position. When the instrument is turned off, the wires are passed through the limit frame 4 and placed in the wire hole, and then the bolts 2 are turned to fix the wires. Then the protective shell 3 is covered, and then the threaded rod 8 is turned to drive the limit plate 5 to move, so that the limit plate 5 cooperates with the limit frame 4 to fix the wires, and the steering plate 7 is turned, the protective plate 9 and the steering plate 7 are fixed by the lock, and the wires are clamped by the internal rubber pad.
