Description

Technical Field

[0001] The utility model relates to the field of circuit breaker base equipment, in particular to a frame type circuit breaker base. Background Art

[0002] A frame circuit breaker is a mechanical switch that can connect, carry and disconnect current under normal circuit conditions, and can also connect, carry for a certain time and disconnect current under specified abnormal circuit conditions. Its main functions include distributing electrical energy, starting asynchronous motors infrequently, and protecting power lines and motors. When a circuit has a serious overload, short circuit or undervoltage fault, the frame circuit breaker can automatically cut off the circuit. With the increasing number of modern electrical equipment and the increase in circuit load, frame circuit breakers play an important role in households, industries, electric vehicle charging stations and medical equipment.

[0003] The circuit breaker base, also called the circuit breaker base or mounting plate, is an important component for fixing and installing the circuit breaker. It is mainly used to bear and support the circuit breaker body. During long-term use, dust, dirt and other impurities may accumulate on the surface of the circuit breaker and inside the circuit breaker base. These impurities may affect the normal operation of the circuit breaker, so it is necessary to regularly remove the circuit breaker base and the circuit breaker from the installation position and clean them.

[0004] At present, when installing the circuit breaker base, it is usually installed and fixed by a guide rail or multiple bolts. When installing by a guide rail, the circuit breaker base needs to be placed along the guide rail and adjusted according to the installation position. After the adjustment, additional parts are needed to fix the circuit breaker base, which increases the complexity of the operation. When installing or disassembling by using multiple bolts, the circuit breaker base needs to be fixed to the installation area by using multiple bolts in sequence, and when using bolts, it is usually necessary to use a wrench to assist in the installation, which results in a long disassembly and assembly time and increases the working time of the operator.

[0005] Therefore, it is necessary to provide a new frame type circuit breaker base to solve the above technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a frame type circuit breaker base.

[0007] The frame type circuit breaker base provided by the utility model comprises a plurality of stabilizing components for installing the circuit breaker base;

A slot for sliding the circuit breaker base is provided on one side of the limiting plate, and the top of the inner wall of the slot is inclined, and protective gaskets are provided on both sides of the inner wall of the slot.

[0009] Preferably, one side of the inner wall of the slot formed by the limiting plate is provided with a plurality of wiring ports for the circuits to pass through and a plurality of protruding blocks.

[0013] Preferably, a heat sink is provided on one side of the circuit breaker base, and the heat sink includes a connecting plate and a plurality of heat transfer plates, one side of the connecting plate is fixedly connected to one side of the circuit breaker base, and a plurality of through grooves are provided on the surface of the connecting plate, one end of the plurality of heat transfer plates are respectively located in the plurality of through grooves, and the other ends of the plurality of heat transfer plates penetrate one side of the inner wall of the through groove and extend to the outside of the connecting plate.

[0014] Preferably, one end of the heat transfer plate located inside the through slot is arranged in an arc shape and fits against one side of the circuit breaker base.

[0015] Compared with the related art, the frame type circuit breaker base provided by the utility model has the following beneficial effects:

[0016] 1. When the circuit breaker base needs to be removed from the installation position, pull the circuit breaker base upward to slide along the inner wall of the slot opened on one side of the limit plate, and take the circuit breaker base out from between the two limit plates, so as to facilitate cleaning. When pulling the circuit breaker base, the protective gaskets arranged on both sides of the inner wall of the slot provide a buffer between the circuit breaker base and the slot, thereby reducing the wear of the circuit breaker base and the slot. The above structure can quickly remove the circuit breaker base from the installation position, which reduces the disassembly and assembly time of the circuit breaker base to a certain extent, and shortens the working time of the operator.

[0027] In the specific implementation process, Figure 1-Figure 5As shown, the frame type circuit breaker base 1 includes a plurality of stabilizing components for installing the circuit breaker base 1, the stabilizing components include a mounting member and a limiting plate 2, one side of the mounting member is provided with an elastic member, and the other end of the elastic member is fixedly connected to one side of the limiting plate 2, one side of the limiting plate 2 is provided with a card slot 3 for the circuit breaker base 1 to slide, and the top of the inner wall of the card slot 3 is inclined, and protective gaskets 4 are provided on both sides of the inner wall of the card slot 3, and one side of the inner wall of the card slot 3 opened by the limiting plate 2 is provided with a plurality of wiring ports 5 for the line to pass through and a plurality of convex The elastic member is a spring 7, one end of the spring 7 is fixedly connected to one side of the mounting member, and the other end of the spring 7 is fixedly connected to one side of the limit plate 2. The mounting member includes a mounting plate 8 and a support plate 9. The bottom end of the support plate 9 is fixedly connected to the top of the mounting plate 8, and one end of the spring 7 is fixedly connected to one side of the support plate 9. The top of the mounting plate 8 is provided with a slide groove 10 for the limit plate 2 to slide. A heat sink 11 is provided on one side of the circuit breaker base 1. The heat sink 11 includes a connecting plate 12 and a plurality of heat transfer sheets 13. One side of the connecting plate 12 is connected to the circuit breaker. The circuit breaker base 1 is fixedly connected to one side, and a plurality of through grooves 14 are provided on the surface of the connecting plate 12. One end of a plurality of heat transfer sheets 13 is respectively located in the plurality of through grooves 14, and the other end of the plurality of heat transfer sheets 13 passes through one side of the inner wall of the through groove 14 and extends to the outside of the connecting plate 12. One end of the heat transfer sheet 13 located inside the through groove 14 is arranged in an arc shape and fits with one side of the circuit breaker base 1. When the circuit breaker base 1 is placed in the card slot 3 opened by the two limit plates 2, through the protective gasket 4 and the plurality of protruding blocks 6 provided on the inner wall of the card slot 3, The friction resistance between the circuit breaker base 1 can be increased, and the protective gasket 4 can fill the small gap between the circuit breaker base 1 and the slot 3, thereby improving the stability of the circuit breaker base 1 inside the slot 3. The multiple wiring ports 5 arranged on the inner wall of the slot 3 can better facilitate the staff to arrange the wires. The circuit breaker device 15 is a Schneider frame circuit breaker MT20H1MT25H. This type of frame circuit breaker has been well used in practical applications, so it will not be described in detail here.

[0028] The working principle provided by the utility model is as follows: when the circuit breaker base 1 needs to be removed from the installation position, the circuit breaker base 1 is pulled upward to slide along the inner wall of the slot 3 opened on one side of the limit plate 2, and the circuit breaker base 1 is taken out from between the two limit plates 2, so as to facilitate the cleaning of the circuit breaker base 1 and the circuit breaker device 15, and the protective gaskets 4 arranged on both sides of the inner wall of the slot 3 provide a buffer between the circuit breaker base 1 and the slot 3, thereby reducing the wear of the circuit breaker base 1 and the slot 3;

[0029] When the circuit breaker base 1 needs to be installed, the circuit breaker base 1 is placed along the card slot 3 opened by the two limit plates 2, and the top of the inner wall of the card slot 3 is squeezed through the bottom of the circuit breaker base 1. Because the top of the inner wall of the card slot 3 is inclined, the two limit plates 2 are pushed to move and the spring 7 is squeezed when it is squeezed. The limit plate 2 applies a certain squeezing force to the circuit breaker base 1 through the rebound force of the spring 7, thereby increasing the stability between the circuit breaker base 1 and the limit plate 2, and when the limit plate 2 moves, it moves along the slide groove 10 opened on the top of the installation plate 8, and the limit plate 2 is blocked and limited by the slide groove 10 to prevent the limit plate 2 from tilting, thereby improving the stability of the limit plate 2;

[0030] When the circuit breaker base 1 is placed in the slot 3 opened by the two limit plates 2, the friction resistance between the circuit breaker base 1 and the slot 3 can be increased by the protective gasket 4 and the multiple protrusions 6 arranged on the inner wall of the slot 3, and the protective gasket 4 can fill the small gap between the circuit breaker base 1 and the slot 3, thereby improving the stability of the circuit breaker base 1 in the slot 3. The multiple wiring ports 5 arranged on the inner wall of the slot 3 can better facilitate the staff to arrange the wires;

[0031] When the heat generated by the circuit breaker is transferred to the circuit breaker base 1, the heat on the surface of the circuit breaker base 1 can be transferred through the arrangement of multiple heat transfer sheets 13, so that the heat can be dissipated to the outside of the circuit breaker base 1. Because one end of the heat transfer sheet 13 located inside the through groove 14 is arranged in an arc shape, it can be more closely fitted with one side of the circuit breaker base 1, reducing the gap between the heat transfer sheet 13 and the circuit breaker base 1, thereby improving the heat transfer efficiency. The arc shape also helps to distribute the heat more evenly to the entire surface of the heat transfer sheet 13, thereby avoiding local accumulation of heat.
