[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-3 , an environmentally friendly circuit breaker, comprising a housing 1, see Figure 1-3A card slot 11 is provided on the surface of the shell 1, and a circuit breaker component is provided in the shell 1. The components are all standard components or components commonly used by technicians in this field, and their working principles are well known to technicians in this field or can be learned from technical manuals. The card slot 11 is used to clamp the protrusion set at the lower end of the protective cover 2. A card block 12 is provided in the card slot 11. The card block 12 is used to limit the moving position of the card rod 24, thereby limiting the opening and closing position of the protective cover 2. The upper end surface of the shell 1 is hinged with a protective cover 2, and the protective cover 2 is provided with a groove 21. A spring 22 is contacted and connected in the groove 21. When the spring 22 is squeezed by the control board 23, it has a compressive elastic force. The elastic force makes the card rod 24 have an automatic tightening effect, thereby quickly fixing the closed position of the protective cover 2. The lower end of the spring 22 is contacted and connected with the control board 23. The control board 23 The lower end of the housing 1 is fixedly connected with a clamping rod 24, and the lower end of the clamping rod 24 is an arc-shaped end. The lower end of the housing 1 is fixedly connected with an anti-slip head 3, which is used to prevent the wires connected to the circuit breaker from being accidentally pulled, resulting in separation from the connection with the circuit breaker, and has an anti-slip function. The anti-slip head 3 is provided with an anti-slip hole 31, and the inner wall of the anti-slip hole 31 is provided with a symmetrical inclined sliding groove 32, and the inclined sliding groove 32 is used to control the sliding trajectory of the slider 34, and the slider 34 is slidably connected in the inclined sliding groove 32. The side of the slider 34 is fixedly connected with a clamping block 33. When the clamping block 33 is squeezed by the squeezing rod 4, the clamping block 33 presses the wire under the action of the inclined sliding groove 32, and the anti-slip wire is pulled and falls off. The anti-slip hole 31 is threadedly connected with the squeezing rod 4, and the squeezing rod 4 is used to control the pressing position of the clamping block 33. The squeezing rod 4 is provided with a connecting hole 41, which is used to pass the connecting wire.

[0024] See also Figure 1 and 2 The shape of the card block 12 is a bar, and the card surface of the card block 12 is an arcuate surface. The card block 12 is in contact with a card rod 24. The arcuate card surface provided on the card block 12 is convenient for the user to quickly insert the card rod 24 into the card slot 11 to fix the position of the protective cover 2, thereby improving the convenience of using the protective cover 2. The shape of the protective cover 2 is square, and the material of the protective cover 2 is environmentally friendly engineering plastic. The protective cover 2 is colorless and transparent. The protective cover 2 is provided to prevent users or children from accidentally touching the circuit breaker, thereby causing incorrect operation, thereby improving the safety of using the circuit breaker.

[0025] See also Figure 2 and 3The shape of the control board 23 is L-shaped. The surface of the control board 23 is slidably connected to the protective cover 2. The lower end of the protective cover 2 is clamped with a card slot 11. The control board 23 is used to control the position of the card rod 24, which is convenient for opening the protective cover 2 and improves the safety of the use of the protective cover 2. The side of the card block 33 is fixedly connected with a protective pad 35. The material of the protective pad 35 is pressure-resistant rubber. The surface of the protective pad 35 is provided with anti-slip grooves. The protective pad 35 can prevent the card block 33 from contacting the wire, protect the skin of the wire from damage, and improve the safety of the use of the anti-slip head 3.

[0026] When installing the wires in the environmentally friendly circuit breaker, the wires can first pass through the connecting hole 41 from bottom to top, and then pass through the anti-drop hole 31 to reach the inside of the circuit breaker. When the wires pass through the anti-drop hole 31, the block 33 is not squeezed by the squeezing rod 4, and drives the slider 34 to slide to the lower end of the inclined slide groove 32 under the action of its own gravity, so the block 33 will not hinder the insertion of the wires. After the wires are connected to the circuit breaker, the squeezing rod 4 is turned clockwise and screwed into the anti-drop hole 31 through the thread, and the block 33 is squeezed upward under the action of the thread. The block 33 moves upward and squeezes the wire under the action of the slider 34 and the inclined slide groove 32, thereby fixing the position of the wire. The anti-dropping head 3 is provided with the function of preventing the wires from falling off, which can prevent the wires from being accidentally pulled and detached from the wiring part of the circuit breaker, thereby improving the connection safety of the circuit breaker. When it is necessary to open the protective cover 2, press the control panel 23 upward with your fingers, and the control panel 23 moves upward to squeeze the spring 22. The spring 22 forms a compressed elastic force. At the same time, the control panel 23 moves upward to drive the clamping rod 24 to move upward and disengage from the contact with the clamping block 12, and then the protective cover 2 is rotated upward. The upward-opening control panel 23 provided on the protective cover 2 can prevent children from accidentally opening the protective cover 2 and causing incorrect operation of the circuit breaker, thereby improving the safety of the use of the protective cover 2.

[0027] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
