Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to an insulating column used for electrical equipment. Background Art

[0002] In the prior art, electrical equipment is usually provided with various PCB boards (such as control boards, drive boards, communication boards, power boards, etc.). The more common PCB board assembly method inside the electrical equipment is a double-layer PCB board structure, and most of the double-layer PCB boards are supported and fixed by insulating columns. However, the common insulating columns are composed of bolts and insulating sleeves with a relatively simple structure. The insulating sleeves are directly sleeved on the outer surface of the bolts. After long-term use, the insulating sleeves of such insulating columns are inevitably likely to fall off, resulting in a lack of good stable fixing measures between the insulating sleeves and the bolts, which can easily cause insulation abnormalities between the double-layer PCB boards and even affect the electrical equipment, seriously affecting the normal operation of the electrical equipment. Utility Model Content

Most of the double-layer PCB boards inside the electrical equipment are supported and fixed by insulating columns. The common insulating columns have a simple structure and are prone to insulation abnormalities on the double-layer PCB boards due to detachment of the insulating sleeve, which seriously affects the normal operation of the electrical equipment. An insulating column for electrical equipment is provided.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an insulating column for electrical equipment, comprising: an insulating column body, a screw is provided at one end of the insulating column body, a nut is provided at the other end of the insulating column body, a first fixing ring is fixedly connected to the inside of the insulating column body, a limiting block is fixedly connected to the inside of the insulating column body, a second fixing ring is connected to the inside of the insulating column body, and one end of the screw is fixedly connected to the fixing block.

[0005] As a preferred implementation, PCB boards are provided at both ends of the insulating column body.

[0006] As a preferred implementation, a first fixing groove matched with a fixing block is formed at one end of the insulating column body.

[0007] As a preferred implementation, a second fixing groove matched with the first fixing ring is formed on the outer surface of the fixing block.

[0008] As a preferred implementation, a third fixing groove matched with a nut is formed at the other end of the insulating column body.

[0009] As a preferred implementation, a fourth fixing groove matched with the second fixing ring is formed on the outer surface of the nut.

[0010] As a preferred embodiment, a threaded hole matching the thread on the screw rod is formed at one end of the nut.

[0011] As a preferred implementation, one end of the fixing block is provided with a limiting groove matched with the limiting block.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] The utility model provides an insulating column body, and a screw is provided at one end of the insulating column body. The screw is fixed inside one end of the insulating column body through a fixing block, a first fixing ring and a limiting block, so that the screw has a good position fixing and limiting measure on the insulating column body. A nut matching the thread on the screw is provided at the other end of the insulating column body, and the nut is fixed inside the other end of the insulating column body with the help of a second fixing ring, so that the nut and the insulating column body have a good anti-slipping measure, and the probability of slipping between the screw and the nut and the insulating column body is reduced, and the phenomenon of insulation abnormality between double-layer PCB boards is reduced, and the insulation measures between the double-layer PCB boards are improved, so as to ensure the normal operation of the electrical equipment.
