Description

Technical Field

[0001] The utility model belongs to the technical field of disconnect switches, and specifically relates to a housing structure of a disconnect switch. Background Art

[0002] A disconnect switch is a switching device used to isolate the power supply in a circuit. Its main function is to cut off and connect the circuit while ensuring safety. In the open state, the disconnect switch can provide an obvious disconnection point to ensure that the circuit is completely powered off, thus protecting the safety of maintenance personnel. They are usually used in high-voltage power systems, such as substations and industrial equipment, as well as solar systems and residential distribution boards.

[0003] The housing of a disconnect switch is usually made of insulating materials, such as ceramics, glass, or special plastics. These materials have good insulation properties and can effectively prevent current leakage and the generation of electric arcs, thereby protecting the safety of operators and equipment.

[0004] Currently, in the existing technology, the heat dissipation effect of the housing structure of traditional disconnect switches is mostly poor. After long-term use of the disconnect switch, abnormal heating may occur in its conductive part, resulting in damage to the conductive components and the housing. This not only affects the normal use of the disconnect switch but also reduces the service life and use efficiency of the housing structure of the disconnect switch.

[0005] Therefore, a housing structure of a disconnect switch is proposed to address the above problems. Summary of the Utility Model

[0026] The following gives specific embodiments.

[0027] Please refer to Figure 1 - Figure 6 , the present utility model provides a housing structure of a disconnect switch, including a base 1, a housing 2 and a mounting box 3.

[0028] During operation, after the static contact 4 is installed inside the first card slot 11, the housing 2 is then placed on top of the base 1, such that the installation slot 7 opened at the bottom of the housing 2 is engaged with the installation slot 7 at the top of the base 1, and the arc-shaped slot 12 is engaged with the heat dissipation slot 22. Furthermore, a plurality of bumps 21 can be inserted inside the first card slot 11, such that the bumps 21 are arranged on one side of the static contact 4 and there is a certain gap between them, avoiding contact between the bottom of the bumps 21 and the static contact 4. As a result, the heat dissipation effect of the static contact 4 can be improved, reducing the situation where the conductive part of the disconnecting switch abnormally heats up after long-term use, leading to damage to the housing, and improving the service life and operating efficiency of the disconnecting switch. Then, one end of the mounting box 3 is sleeved outside one end of the housing 2, and then the mounting box 3 is pressed, such that the inner wall of the bottom of the mounting box 3 is attached to the outer side of the connecting plate 15. Furthermore, a plurality of positioning blocks 32 are inserted inside the positioning screw holes 16, and then a screw is rotated through the positioning block 32 and into the positioning screw hole 16 to fix the mounting box 3 at one end of the base 1, enabling rapid assembly of the housing structure of the disconnecting switch.

Then the housing 2 is covered on the top of the base 1, so that the installation slot 7 opened at the bottom of the housing 2 is engaged with the installation slot 7 on the top of the base 1. The clamping block 13 is clamped at both ends of the heat dissipation slot 22, so that the insertion rod 14 is inserted into the insertion hole 23, and then a plurality of convex blocks 21 are inserted into the inner side of the first card slot 11, so that the convex blocks 21 are arranged on one side of the static contact 4. Then the long screw passes through the insertion rod 14 and is screwed into the insertion hole 23 to fix the housing 2 on the top of the base 1. By moving the installation box 3, the connection slot 33 is clamped on the outside of the connecting rod 24, and then the installation box 3 is pressed, so that the inner wall of the bottom of the installation box 3 is attached to the outside of the connecting plate 15. Then a plurality of positioning blocks 32 are inserted into the positioning screw holes 16, and then the screw is rotated through the positioning block 32 and into the positioning screw hole 16 to fix the installation box 3 at one end of the base 1, completing the assembly work of the disconnecting switch.
