Description

An adjustable insulating bus clamp

technical field

The invention relates to a bus clamp, in particular to an adjustable insulating bus clamp used in a low-voltage switch cabinet.

Background technique

The traditional busbar clamps are determined according to the size of the busbar. Once the busbar is replaced, the busbar clamp must also be replaced, which brings a lot of inconvenience to production and maintenance.

Contents of the invention

The technical problem to be solved by the present invention is to provide an adjustable insulating busbar clamp, which can reduce the workload when the busbar is replaced, reduce the material cost and increase the service life.

In order to solve the problems of the technologies described above, the technical solution of the present invention is:

An adjustable insulated busbar clamp includes a busbar clamp body and an adjustable clamping block. The busbar clamp body is provided with several fixing slots. The adjustable clamping block includes a fixed base and a steering clip. The fixed The base is a cylindrical structure, the height h1 of the fixed base=the depth h2 of the fixed slot, the shape of the fixed slot matches the shape of the fixed base, the fixed base is set in the fixed slot, and is connected by bolts It is fixed on the body of the bus clamp, and the fixed base is provided with a clamping slot of cuboid structure, the depth h3 of the clamping slot is less than the height h4 of the steering clamp, and the interference fit of the steering clamp is set In the slot where the clip is placed, the steering clip is a cuboid structure, and two bus bar slots are arranged parallel to each other on the steering clip, and the included angle a between the bus bar slot and the outer wall of the steering clip is 45° °, the depth h5 of the busbar clamping groove=the height h4*2/3 of the steering clamp.

In the aforementioned adjustable insulating bus bar clamp, the side length of the steering clip is less than the diameter of the fixed base.

In the above-mentioned adjustable insulating bus clamp, the inner surface of the fixed base and the outer surface of the steering clip are both provided with a frosted layer.

The beneficial effects of the present invention are:

1. The body of the busbar clamp and the adjustable clamping block of the present invention are split structures, which are easy to install and disassemble. When in use, the adjustable clamping blocks with suitable busbar slots can be replaced according to the size of different busbars, reducing the workload when replacing the busbars , Reduce material and labor costs.

2. The adjustable clamping block of the present invention is composed of a fixed base and a steering clip. The fixed base plays a role of fixing the foundation, and the steering clip can change the fixed direction according to the needs of use, which is more flexible and avoids The steering clamp block is directly in contact with the body of the busbar clamp, which will cause wear to the body of the busbar clamp and increase the service life.

3. The depth h3 of the clamping block placement slot < the height h4 of the steering clamp, the depth of the busbar clamping slot h5 = the height of the steering clamp h4*2/3, which can firmly clamp the busbar into the busbar clamp, which is safe and reliable. Good stability.

4. Both the inner surface of the fixed base and the outer surface of the steering clip are provided with a frosted layer, which increases the adhesion between the two and is more firm and reliable.

detailed description

As shown in the figure, an adjustable insulating busbar clamp includes a busbar clamp body 1 and an adjustable clamping block 2. The busbar clamp body 1 is provided with several fixing slots 3, and the adjustable clamping block 2 includes a fixed base. Seat 4 and steering clip 5, the fixed base 4 is a cylindrical structure, the height h1 of the fixed base 4=the depth h2 of the fixed slot 3, the shape of the fixed slot 3 is the same as the shape of the fixed base 4 Matched, the fixed base 4 is arranged in the fixed card slot 3, and is fixed on the busbar clamp body 1 by the bolt 9, and the clamp block of the cuboid structure is provided on the fixed base 4 to place the card slot 6, and the clamp block is placed on the card The depth h3 of the groove 6<the height h4 of the steering clip 5, the steering clip 5 is arranged in the clamp block placement slot 6 with an interference fit, the steering clip 5 is a cuboid structure, and the steering clip 5 is mutually Two busbar clamping grooves 7 are arranged in parallel, the angle a between the busbar clamping groove 7 and the outer wall of the steering clamp 5 is 45°, the depth h5 of the busbar clamping groove 7=the height h4 of the steering clamp 5 *2/3, the side length b of the steering clip 5 < the diameter d of the fixed base 4 , the inner surface of the fixed base 4 and the outer surface of the steering clip 5 are both provided with a frosted layer 8 .

The main body of the bus clamp and the adjustable clamping block of the present invention are split structures, which are convenient to install and disassemble. When in use, the adjustable clamping blocks with suitable bus bar slots can be replaced according to the size of different bus bars, thereby reducing the workload of bus bar replacement and reducing the Material and labor costs.

The adjustable clamping block of the present invention is composed of a fixed base and a steering clip. The fixed base plays a role of fixing the foundation, and the steering clip can change the fixed direction according to the needs of use, which is more flexible and avoids turning The clip block directly contacts with the body of the busbar clamp, causing wear to the body of the busbar clamp and increasing the service life.

The depth h3 of the clamp block placement card slot<the height h4 of the steering clip, the depth of the busbar clip h5=the height of the steering clip h4*2/3, can firmly clamp the busbar into the busbar clip, safe, reliable and stable it is good.

Both the inner surface of the fixed base and the outer surface of the steering clip are provided with a frosted layer, which increases the adhesion between the two and is more firm and reliable.

The description and application of the present invention here are illustrative, and are not intended to limit the scope of the present invention to the above-mentioned embodiments. Therefore, the present invention is not limited by this embodiment, and any technical solutions obtained by adopting equivalent replacement are included in this within the scope of invention protection.
