Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of lead wire device, specifically is a cable lead wire device for electric cabinet. BACKGROUND

[0002] The cable lead wire in the electric cabinet is the key link connecting the external power supply and the internal equipment, and its main role is to ensure the normal power supply and signal transmission of various electrical equipment in the electric cabinet. Through the cable lead wire, the external power supply can be effectively introduced into the electric cabinet to provide necessary power support for the internal circuit breaker, contactor, frequency converter and other equipment. At the same time, the cable lead wire also undertakes the function of transmitting control signals and monitoring signals, so that the automatic control system in the electric cabinet can receive signals from sensors and switches in real time, and feed back the equipment state to the external system. The timeliness and accuracy of such signal transmission are the basis for ensuring the safe operation of equipment and the stability of the system. When performing cable lead wire operation, preparation work is needed first, including selecting appropriate tools and materials, and formulating a detailed lead wire plan according to the wiring diagram of the electric cabinet. Next, select the appropriate specification of cable, and introduce it at the inlet of the electric cabinet, ensuring the sealing of the inlet. Then, use the wire stripper to strip the insulation layer of the cable, and connect the cable to the corresponding terminal according to the wiring diagram, ensuring firm connection. For cables that need to be crimped, use crimping pliers for processing to ensure good electrical contact. After completing the lead wire, the cable is labeled and arranged to keep the inside of the electric cabinet clean and facilitate future maintenance and repair. However, during the lead wire and cable extraction process, the staff needs to pull the cable, at which time the cable rubs against the holes in the electric cabinet. The cable is composed of a conductor and an insulating material, and the main function of the insulating layer is to prevent current leakage and external interference. When the cable rubs frequently in the hole, the insulating layer will have scratches, cracks or other forms of damage, which will cause current leakage and increase the risk of short circuit, and even may cause fire and other serious consequences.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0018] Please refer to Figures 1-5 The utility model provides an embodiment: a cable wire guide device for an electric appliance cabinet, including H type back seat 1 and right and left side outer wall on H type back seat 1 welding installation's right-angle seat 4, right-angle seat 4 with electric appliance cabinet carries out the bolt joint, the inside of H type back seat 1 is provided with the double-roller wire entry structure 2 for assisting cable and reducing friction, the center position of H type back seat 1 surface is provided with hollow part 3, the outer wall on the side of right-angle seat 4 away from double-roller wire entry structure 2 is provided with V-shaped wire guide structure 5, two V-shaped wire guide structures 5 about the setting center reference plane of H type back seat 1 is symmetrical structure;

[0019] The inside of right-angle seat 4 is provided with two symmetrical through holes 401, and the left and right outer walls of H type back seat 1 are both provided with rectangular cutouts 101. H type back seat 1 and right-angle seat 4 are both made of aluminum alloy components. Right-angle seat 4 is bolted to the inner wall of the electric appliance cabinet through the through holes 401, so that the wire guide device can be stably installed on the cabinet body.

[0020] The double-roller wire entry structure 2 includes two symmetrical steel rollers 201 rotatably installed in the inside of H type back seat 1. The outer periphery of the steel roller 201 is bonded with a rubber pad 202. The cable passes between the two steel rollers 201. The cable body contacts the rubber pad 202 to reduce the pressure exerted by the steel roller 201 on the cable during the wire guiding process, thereby effectively protecting the integrity of the cable.

[0021] The V-shaped lead structure 5 includes a front rubber plate 501 fixed on one side of the outer wall of the right-angle seat 4 and a V-shaped rubber sleeve 502 integrally formed on the side of the front rubber plate 501 away from the outer wall of the right-angle seat 4. The top edge and the bottom edge of the V-shaped rubber sleeve 502 are provided with arc-shaped bent edges 503. The opening degree of the V-shaped rubber sleeve 502 is smaller than the distance between the two steel rollers 201. The groove design of the V-shaped rubber sleeve 502 provides a relatively loose space, so that the cable will not be squeezed and rubbed too much when passing through, effectively reducing the contact area between the cable and the cabinet body, and reducing the risk of wear and damage.

[0022] When the lead-through device passes through multiple cables, the V-shaped rubber sleeve 502 and the front rubber plate 501 can be expanded up and down to adapt, and then tightened with a cable tie.

[0023] In use, the staff should first ensure that the required cables, tools and equipment are complete, and check the internal structure of the electrical cabinet to ensure that there are no obstacles affecting the introduction of the cable. Place the H-shaped back seat 1 at an appropriate position on the inner wall of the electrical cabinet, usually near the inlet. Then use the right-angle seat 4 and the bolt to fix the H-shaped back seat 1 on the inner wall of the cabinet body to ensure its stability. After fixing, check the installation status of the H-shaped back seat 1 to ensure that it is not loose to avoid unnecessary interference during the lead-through process. Prepare the cable to be introduced, ensure that the length of the cable is sufficient, and check the insulation layer and physical state of the cable to confirm that it is not damaged. Introduce one end of the cable from the hole of the electrical cabinet. After the cable passes through the hole of the cabinet body, it needs to smoothly enter the double-roller lead-through structure 2. The double-roller lead-through structure 2 can make the cable advance in a rolling manner when passing through, reducing friction. At this time, the staff gently pulls the cable, and the rotation of the double rollers will help the cable move smoothly. Then the cable will enter the hollow part 3 and enter the V-shaped lead-through structure 5. The V-shaped lead-through structure 5 can effectively support and guide the cable to ensure that it does not deviate from the predetermined track during the introduction process and ensure that the shape of the cable remains normal, avoiding significant twisting or bending. When the cable is successfully connected to the electrical equipment, the staff uses a cable tie to tie into the two V-shaped lead-through structures 5, so that the V-shaped lead-through structures 5 tightly hold the cable to ensure that it will not be affected by external forces during subsequent operation.
