Description

Technical Field

[0001] The utility model relates to the technical field of electrical switches, in particular to an electrical switch. Background Art

[0002] An electrical switch (also known as a circuit breaker) is an electrical appliance used to control and protect a circuit. Its main function is to disconnect the circuit when a short circuit or overload occurs in the circuit, thereby preventing damage to the appliance. It can quickly cut off the current and ensure circuit safety. Electrical switches have a strong power-off capability and can be used in high-voltage, high-current circuits and have a long service life. However, traditional electrical switches have the following shortcomings when used:

[0003] 1. The switch of the electrical switch is not waterproof, and water vapor can easily enter during the rainy season, causing damage to internal components.

[0004] 2. The electrical switches assembled side by side are close to each other and have small gaps, which is not conducive to heat dissipation.

[0005] We therefore propose an electrical switch. Utility Model Content

[0010] A protective cover, the protective cover is sleeved on one side of the switch body, one side of the protective cover is provided with two grooves, the two grooves are integrally formed with buckles, the buckles and the clamping blocks cooperate to limit the protective cover, the inner wall of the protective cover is provided with a sealing groove, and a sealing ring is provided in the sealing groove;

[0011] Two connecting plates are respectively installed on both sides of the switch body, and a plurality of protrusions are integrally formed on the side of the two connecting plates close to each other, and ventilation grooves are arranged between adjacent protrusions.

[0012] In a possible design, two thread grooves are provided on both sides of the switch body, a through assembly hole is provided on one side of some of the protrusions, and a screw is provided between the thread groove and the assembly hole.

[0015] In a possible design, two positioning blocks are integrally formed on both sides of the switch body, and a plurality of positioning grooves are formed on one side of the protective cover, and the positioning blocks and the positioning grooves are matched with each other.

[0016] In a possible design, the openings of the plurality of limiting grooves and the plurality of positioning grooves are all provided with inclined surfaces.

[0017] In this application, the protective cover can be made of ABS plastic, which has high elasticity and toughness. When using the electrical switch, just hold the protective cover and pull it off, and the buckle can quickly deform and recover;

[0018] When dissipating heat, part of the air passes directly through the ventilation slots, and part of the air passes through the air holes into the inner cavity and the connecting slots, and finally flows out from the air holes, which increases the contact area with the air and facilitates the heat dissipation of the electrical switch.

[0019] Beneficial effects:

[0020] In the utility model, the electrical switch can provide closed protection for the switch of the electrical switch to prevent water vapor from entering by setting multiple structures such as a protective cover, a sealing ring and a buckle;

[0021] In the utility model, the electrical switch can separate the electrical switches arranged side by side by setting the connecting plate, so that a certain gap is left between the electrical switches, which is convenient for air circulation, increases the contact area with the air, and further facilitates the heat dissipation of the electrical switches;

[0022] In the utility model, the electrical switch can position adjacent electrical switches through the arrangement of the limit block and the limit groove, thereby improving the stability of the installation of the electrical switch;

[0032] In another aspect of the present embodiment, specifically, blocks 5 are integrally formed on both sides of the switch body 1. Such a design not only increases the structural strength of the switch body 1, but also facilitates the subsequent assembly with the protective cover 2. The protective cover 2 is sleeved on one side of the switch body 1 to protect the switch body 1 and prevent dust, water and other debris from entering the switch body 1 and affecting its normal operation. Two grooves 15 are provided on one side of the protective cover 2, and buckles 16 are integrally formed in the two grooves 15. When the protective cover 2 is sleeved on the switch body 1, the buckle 16 cooperates with the block 5 to limit the protective cover 2 and prevent it from falling off. At the same time, a sealing groove is provided on the inner wall of the protective cover 2, and a sealing ring 19 is provided in the sealing groove, which further improves the sealing between the protective cover 2 and the switch body 1 and enhances the protective effect.

[0033] In another aspect of the present embodiment, two connecting plates 3 are respectively installed on both sides of the switch body 1, and a plurality of protrusions 7 are integrally formed on the sides of the two connecting plates 3 that are close to each other, and ventilation grooves 8 are provided between adjacent protrusions 7. Such a design enables the connecting plates 3 to not only play a fixing and supporting role, but also to dissipate heat through the ventilation grooves 8, thereby improving the heat dissipation efficiency of the electrical switch. An inner cavity 11 is provided on the other side of the plurality of protrusions 7, and connecting grooves 12 are connected between adjacent inner cavities 11. A plurality of air holes 14 are provided on the top and bottom of the two connecting plates 3, and the air holes 14 are connected to the connecting grooves 12. Such a structure allows air to enter the connecting grooves 12 and the inner cavity 11 through the air holes 14, thereby further improving the heat dissipation performance of the electrical switch.

This connection method is simple and convenient, and the connection is firm and reliable.

[0037] In another aspect of this embodiment, in order to further optimize the heat dissipation performance of the electrical switch, the surfaces and bottoms of the plurality of bumps 7 are arc-shaped. This design makes the surface of the bump 7 smoother and the air flow smoother, thereby improving the heat dissipation efficiency.

[0038] In another aspect of the present embodiment, a plurality of limit grooves 13 are provided on one side of one of the connecting plates 3, and a plurality of limit blocks 9 are integrally formed on one side of the other connecting plate 3.
