Description

Technical Field

[0001] The utility model relates to the technical field of power equipment, and particularly relates to a quick wiring device for a primary-secondary integrated pole-mounted circuit breaker. Background Art

[0002] In modern power systems, the primary-secondary integrated pole-mounted circuit breaker, as an important distribution equipment, is widely used in the automatic control and protection of outdoor power grids. This type of circuit breaker integrates functions such as high-voltage switching, measurement, protection, and communication, and can realize remote monitoring and intelligent management of the power grid. Before the circuit breaker is put into formal use, it needs to pass performance tests first. The tests usually include multiple aspects such as measurement of electrical parameters, verification of operating characteristics, and inspection of tolerance capabilities. Among them, quickly and accurately connecting the test circuit is an indispensable link in the test process. However, the traditional test wiring method has many limitations. For example, using bolt connection is time-consuming and inefficient, and cannot meet the requirements of large-scale tests. Therefore, we propose a quick wiring device for a primary-secondary integrated pole-mounted circuit breaker. Content of the Utility Model

[0003] The purpose of the utility model is to provide a quick wiring device for a primary-secondary integrated pole-mounted circuit breaker, which has the advantages of simple operation, firm and rapid connection, and solves the problems in the prior art.

A first clamping plate is arranged directly above the second clamping plate. The size of the first clamping plate is larger than that of the second clamping plate. Four corners of the bottom surface of the first clamping plate are respectively connected to the bottom plate through a compression spring. Press rods are symmetrically arranged on both sides of the second clamping plate. A groove for placing a cable connection piece is arranged at the center of the top surface of the second clamping plate.

[0006] Preferably, a lifting block is arranged at one end of the press rod facing the second clamping plate. The press rod and the lifting block are of an integral structure and are in an "L" shape. The lifting block is located in the gap between the first clamping plate and the second clamping plate, and the top of the lifting block abuts against the bottom of the first clamping plate.

[0007] Preferably, a pivoting part is arranged at the connection between the press rod and the lifting block. The press rod and the lifting block are rotatably connected to the bottom plate through the pivoting part.

[0008] Preferably, the longitudinal section of the groove is an isosceles trapezoid with a wider top and a narrower bottom. The bottom size of the groove is the same as the bottom size of the cable connection piece.

[0010] Preferably, a wiring board is provided on one side of the second clamping plate. The wiring board penetrates into the second clamping plate, and the bottom surface of the groove is the upper surface of the wiring board.

[0011] Preferably, an arc-shaped groove for accommodating the cable wire body is formed on the side of the second clamping plate opposite to the wiring board, and the arc-shaped groove communicates with the groove.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the present utility model, when the pressing rods on both sides are pressed simultaneously, the pressing rods rotate around the pivot joint, the pressing rods drive the lifting blocks to rotate upward, the lifting blocks jack up the first clamping plate. At this time, the compression spring is stretched. The cable connection terminal is inserted into the gap between the first clamping plate and the second clamping plate, so that the cable connection terminal is placed at the bottom of the groove in contact with the wiring board. After the placement is completed, the pressing rods are released, and the first clamping plate presses the cable connection terminal under the pulling of the compression spring, thereby completing the rapid connection between the cable connection terminal and the wiring board.

[0024] In order to solve the problems of complex wiring and inconvenient operation existing in the prior art, the following technical solutions are given. Please refer to Figure 1-8 ;

[0025] A quick wiring device for a primary-secondary integrated pole-mounted circuit breaker, including a bottom plate 3, a second clamping plate 2 is fixed on the bottom plate 3, a first clamping plate 1 is arranged directly above the second clamping plate 2, the size of the first clamping plate 1 is larger than that of the second clamping plate 2, and the four corners of the bottom surface of the first clamping plate 1 are respectively connected to the bottom plate 3 through a compression spring 4. Pressing rods 5 are symmetrically arranged on both sides of the second clamping plate 2, and a groove 7 for placing a cable connection piece 6 is arranged at the center of the top surface of the second clamping plate 2.

[0026] A lifting block 8 is arranged at one end of the pressing rod 5 facing the second clamping plate 2. The pressing rod 5 and the lifting block 8 are of an integral structure and are in an "L" shape. The lifting block 8 is located in the gap between the first clamping plate 1 and the second clamping plate 2, and the top of the lifting block 8 abuts against the bottom of the first clamping plate 1. A pivoting portion 9 is arranged at the connection between the pressing rod 5 and the lifting block 8, and the pressing rod 5 and the lifting block 8 are rotatably connected to the bottom plate 3 through the pivoting portion 9. When it is necessary to lift the first clamping plate 1, press the pressing rods 5 on both sides simultaneously with the hand. The pressing rod 5 rotates around the pivoting portion 9, and the pressing rod 5 drives the lifting block 8 to rotate upward. The lifting block 8 jacks up the first clamping plate 1 to form a gap for the cable connection piece 6 to pass through between it and the second clamping plate 2.

[0027] The longitudinal section of the groove 7 is an isosceles trapezoid with a wider top and a narrower bottom. The bottom size of the groove 7 is the same as the bottom size of the cable connection piece 6. One side of the second clamping plate 2 is connected to a wiring board 10 on the circuit breaker body 13. The wiring board 10 penetrates into the second clamping plate 2, and the bottom surface of the groove 7 is the upper surface of the wiring board 10. When the cable connection piece 6 is placed on the second clamping plate 2, the shape of the groove 7 can make the cable connection piece 6 automatically return to the bottom of the groove 7 and contact the wiring board 10. The thickness of the cable connection piece 6 is greater than the depth of the groove 7. After the cable connection piece 6 is placed in the groove 7, the first clamping plate 1 presses and fixes the cable connection piece 6 under the action of the compression spring 4; an arc-shaped groove 12 for accommodating the cable wire body 11 is opened on the side of the second clamping plate 2 opposite to the wiring board 10, and the arc-shaped groove 12 communicates with the groove 7.

[0028] Working principle: Before placing the cable terminal 6, press the pressing rods 5 on both sides simultaneously. The pressing rods 5 rotate around the pivot portion 9, and the pressing rods 5 drive the lifting block 8 to rotate upward. The lifting block 8 jacks up the first clamping plate 1. At this time, the compression spring 4 is stretched. Insert the cable terminal 6 into the gap between the first clamping plate 1 and the second clamping plate 2, so that the cable terminal 6 is placed at the bottom of the groove 7 and contacts the wiring board 10. After the placement is completed, release the pressing rods 5. The first clamping plate 1 presses the cable terminal 6 under the pulling force of the compression spring 4, thus completing the quick connection.
