Description

Technical Field

[0001] The utility model relates to the technical field of vacuum switch accessories, and more particularly to an insulating bracket for an outdoor vacuum switch. Background Art

[0002] Outdoor vacuum switches are essential electrical components in power systems, used to connect and disconnect load currents, overload currents, and short-circuit currents. Outdoor vacuum switch installations typically require support and fixation with mounting brackets. Traditional mounting brackets have proven ineffective, leading the inventors to research and propose this solution. Utility Model Content

[0003] The purpose of the utility model is to provide an outdoor vacuum switch insulating bracket in order to solve the above technical problems.

[0004] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0005] An outdoor vacuum switch insulating bracket includes a back frame, a side frame, an extension frame, and a mounting ear. A sliding opening is integrally formed on the side end of the back frame, and a protrusion is integrally formed on the end of the side frame close to the sliding opening. The protrusion slides with the sliding opening, and a connecting piece is provided through the protrusion. The end of the connecting piece is threadedly connected to the back frame. The extension frame is plugged into the side frame, and the mounting ear is plugged into the back side of the back frame. The mounting ear is penetrated by a mounting hole.

[0006] The insulating bracket in this utility model achieves overall insulation and can accommodate vacuum switches of a certain width. The bracket is adjusted and fixed using the side brackets. To secure the switch, simply place the switch between the two side brackets, twist the connectors so that the side brackets face inward against the switch, and then screw the prefabricated connectors at the top or bottom of the switch onto the back bracket. This completes the installation of the switch on the insulating bracket. The side brackets enhance the fixing of the switch, while the extension brackets increase the contact area with the side ends of the switch.

[0007] A preferred technical solution: the connecting piece is a screw.

[0008] A preferred technical solution: The back frame is prefabricated with several heat dissipation holes and screw holes. The screw holes can be drilled as needed. The back frame is then pre-set with corresponding holes to match the mounting and locking position of the vacuum switch. The heat dissipation holes are mostly circular or rectangular in shape, and their location and number can be flexibly adjusted according to needs.

[0009] A better technical solution: The side frame is prefabricated with perforations, which are convenient for laying the wires connected to the vacuum switch. The wires on the vacuum switch can be arranged in a branch layout, which is convenient for later targeted maintenance and makes the wire layout clearer.

[0010] A preferred technical solution: The extension frame is made of elastic plastic, which is insulating and elastic, making it easy to wrap the vacuum switch.

[0011] A preferred technical solution: the connection position between the mounting ear and the back frame is staggered with the sliding opening.

[0012] A preferred technical solution: the back frame, side frames and mounting ears are made of polyvinyl chloride, which is insulated and non-conductive.

[0013] The beneficial effects of the utility model are as follows:

[0014] This utility model utilizes side brackets to enhance the securement of the vacuum switch, while the extension brackets increase the contact area with the side ends of the vacuum switch. This structure effectively assists in securing the vacuum switch, ensuring that the switch remains securely in place during installation and removal, even when disconnected from the back bracket. This significantly improves installation convenience and safety during removal. The brackets are constructed of insulating material to ensure effective insulation. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0021] like Figures 1 to 3 As shown, this embodiment provides an insulating support for an outdoor vacuum switch, comprising a back frame 1, side frames 2, an extension frame 23, and mounting ears 3. A sliding opening 11 is integrally formed on the side end of the back frame 1. A protrusion 21 is integrally formed on the end of the side frame 2 that faces the sliding opening 11. The protrusion 21 slidably engages with the sliding opening 11. A connector 4 is provided through the protrusion 21, the distal end of which is threadedly connected to the back frame 1. The extension frame 23 is plugged into the side frame 2. The mounting ears 3 are plugged into the back side of the back frame 1, and the mounting ears 3 are provided with mounting holes 31.

[0022] Furthermore, the connecting member 4 is a screw.

[0023] Furthermore, a plurality of heat dissipation holes and screw holes are prefabricated on the back frame 1 .

[0024] Furthermore, a through hole 22 is prefabricated on the side frame 2 .

[0025] Furthermore, the extension frame 23 is made of elastic plastic.

[0026] Furthermore, the connection position between the mounting ear 3 and the back frame 1 is offset from the sliding opening 11 .

[0027] Furthermore, the back frame 1, the side frame 2, and the mounting ears 3 are made of polyvinyl chloride, and the depth of the mounting ears 3 is usually 3-5 cm to ensure the connection effect.

[0028] Outdoor vacuum switches, which require high waterproofing, are typically installed inside a power box using an auxiliary plate 5. The plate is equipped with several mounting holes that match the shape of the mounting ears 3. These densely spaced holes allow the insulating bracket to be flexibly mounted on the plate, depending on the spacing between the ears 3. If the plate is mounted on a flat wall, screws are used. If it is mounted on a pole, wire is used to secure the plate. The plate is typically less than 1 cm thick.

[0029] The insulating bracket can be quickly installed by inserting the mounting ears 3 into the mounting holes on the auxiliary plate 5. The vacuum switch is first fixed with the aid of the side frame 2, and then the vacuum switch is locked and installed on the back frame 1. The wires can be laid along the through holes 22 on the side frame 2, or first pass through the side frame 2 and then pass through the mounting holes 31 on the mounting ears 3.
