DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1-6 As shown, a circuit breaker convenient for wiring comprises a circuit breaker body 1, a wiring port 2 and a conductive plate 3. A fixing column 4 is slidably mounted at the top of the wiring port 2 in the circuit breaker body 1, and a wiring structure 5 is arranged between the fixing column 4 and the circuit breaker body 1;

[0027] The wiring structure 5 includes a slide groove 501, which is opened at a side position on the top of the circuit breaker body 1, and a driven clamping plate 503 is slidably installed in the slide groove 501. Three springs 502 are fixedly connected between a side surface of the driven clamping plate 503 and the inner surface of the slide groove 501. A connecting plate 505 is fixedly connected to the top of one side of the surface of the fixed column 4, and an active clamping plate 504 is fixedly connected to one end of the connecting plate 505. A baffle 506 is fixedly connected to one side of the driven clamping plate 503 at a top position.

[0028] In this embodiment, the active clamping plate 504 is meshed with the driven clamping plate 503 , and the bottom end of the baffle 506 is in close contact with the top surface of the circuit breaker body 1 .

[0029] The driven clamping plate 503 serves as a unidirectional limit, and the active clamping plate 504 can move downward freely, but will be limited if it moves upward. The baffle plate 506 serves as a shield to prevent dust from falling into the slide groove 501.

[0030] In this embodiment, a trapezoidal groove is provided in the middle of the conductive plate 3, a trapezoidal block is provided at the bottom end of the fixing column 4, and the trapezoidal groove and the trapezoidal block are adaptively matched.

[0031] The trapezoidal groove and the trapezoidal block can better fix the wire placed between the conductive plate 3 and the fixing column 4, and effectively prevent the wire from falling off.

[0032] In this embodiment, a pressing structure 6 is provided between the fixed column 4 and the circuit breaker body 1, and the pressing structure 6 includes a movable groove 601, and the movable groove 601 is opened at the top of the circuit breaker body 1. A fixing seat 602 is fixedly installed on the top of the fixed column 4 and the connecting plate 505, and a connecting rod 1 603 is rotatably installed in the fixing seat 602. The tops of the two connecting rods 1 603 are respectively rotatably installed with connecting rods 2 604 and adjusting rods 605, and the bottom end of the adjusting rod 605 is fixedly connected with a pressing rod 606, and the tops of the connecting rod 2 604 and the adjusting rod 605 are fixedly installed with an incomplete gear 607, and a pressing seat 609 is fixedly installed at a position near the movable groove 601 at the top of the circuit breaker body 1, and a connecting column 608 is fixedly installed inside the pressing seat 609 near the top.

[0033] The pressing structure 6 can change the manual pressing and pulling of the fixing column 4 into indirect control by pulling and pressing the pressure rod 606, which is more convenient and labor-saving, and the operation is more flexible and convenient.

[0034] In this embodiment, the two incomplete gears 607 are meshed and connected with each other, and the incomplete gears 607 are rotatably mounted on the surface of the connecting column 608 .

[0035] Through the mutual meshing of the incomplete gears 607, the two connecting rods 603 can be controlled at the same time, and the connecting column 608 makes the rotation of the incomplete gears 607 more stable.

[0036] In this embodiment, both sides of the pressing seat 609 are open structures, and the bottom end of the pressing seat 609 is also an open structure.

[0037] The openings on both sides of the pressing seat 609 will not hinder the work of the connecting rod 1 603, the connecting rod 2 604 and the adjusting rod 605, and the opening at the bottom will not affect the lifting of the fixing column 4.

[0038] In this embodiment, the pressure rod 606 is composed of a round rod and a round ball, and the round ball is located at the bottom end of the pressure rod 606 .

[0039] The round ball and round rod of the pressing rod 606 make it easier for the operator to exert force when manually pressing and pulling the pressing rod 606 .

[0040] It should be noted that the utility model is a circuit breaker that is convenient for wiring. When in use, after removing the outer skin of one end of the wire, the other end of the wire is placed between the conductive plate 3 and the fixed column 4 in the wiring port 2. By pressing the pressure rod 606, the pressure rod 606 moves downward to drive the adjustment rod 605 and the incomplete gear 607 to rotate along the connecting column 608. Through the mutual engagement of the two incomplete gears 607, the connecting rod 2 604 is driven to rotate in the opposite direction. The connecting rod 2 604 and the adjusting rod 605 will drive the connecting rod 1 603 to rotate and move downward. The connecting rod 1 603 drives the fixed seat 602 to move downward, thereby driving the fixed column 4 to move downward, so that the wire is pressed tightly on the conductive plate 3. The pressing seat 609 plays a role in preventing dust, and the movable groove 601 ensures that the pressing structure 6 will not be hindered when working.

[0041] When the fixed column 4 moves downward, the active card plate 504 is driven to move downward through the connecting plate 505. When the active card plate 504 moves downward, it will squeeze the driven card plate 503. Under the joint action of the elastic force of the spring 502, the driven card plate 503 will reciprocate along the slide groove 501. When the wire is pressed tightly, the driven card plate 503 plays a limiting role, so that the position of the active card plate 504 is fixed and cannot move upward, thereby fixing the wire, and the baffle 506 plays a role in preventing dust from falling into the slide groove 501;

[0042] When a line change operation is required, the driven card plate 503 is pushed to squeeze the spring 502 so that the driven card plate 503 is separated from the active card plate 504, and then the pressure rod 606 is pulled upward to move the fixed column 4 upward so that the wire can be separated.

[0043] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
