Description

Technical Field

[0001] This utility model relates to the field of wire harness structure technology, and in particular to a wire harness structure for transformers. Background Technology

[0002] A transformer is an electrical device used to change alternating current (AC) voltage, and it is widely used in power systems, industrial equipment, and electronic equipment. The basic principle of a transformer is electromagnetic induction; by transferring magnetic flux between two or more coils, it increases or decreases the voltage.

[0003] Transformers are indispensable and crucial equipment in modern power systems and industrial devices. For example, Chinese Patent Publication No. CN212411799U discloses a protective wire harness structure for transformers, belonging to the field of transformer technology. It includes a housing, with the lower surface of the inner wall of the housing overlapping the lower surface of the equipment body. The outer surface of the equipment body is fitted with protective corner protectors. The left and right sides of the inner wall of the housing are fixedly connected to the left and right sides of a support plate, respectively. This protective wire harness structure for transformers, through the use of sliders, support rods, and springs, first involves winding the wires around a first rotating shaft. The operator presses four compression blocks with both hands, causing two compression blocks to move the support rods closer together. The two support rods then move two sliders towards each other, compressing the telescopic rod and spring, causing the sliders to disengage from the left-side groove. The fixing rod is then pulled outwards, and the spring force pushes the two sliders outwards and into the right-side groove. This increases the number of fixed wires, enhancing the wire harnessing effect, eliminating the need for multiple wire harnessing operations, and is simple and aesthetically pleasing.

[0004] Currently, when connecting transformers to power lines, since conventional transformer lines have the same length specifications, if the lines are too long after connection, they are prone to sagging if not properly secured, affecting the safety of the transformer. Ordinary securing methods often involve suspending and fixing the lines with a single rope, which is prone to breakage after prolonged use. If the transformer is located in an area where people are active, this poses a danger to their lives. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a wire harness structure for transformers. To achieve the above objective, this utility model adopts the following technical solution:

[0006] Design a cable harness structure for a transformer, including a base, a transformer body fixed on the top of the base, terminals fixed on the top of the transformer body, extension seats on both sides of the base, the extension seats slidingly inserted into the base and fixed at the connection position of the extension seats and the base by screws, a support plate on the top of the extension seats, lead wire holes on the surface of the support plate, the lead wire holes corresponding one-to-one with the positions of the terminals, the support plate is located on one side of the transformer body and fixedly assembled to the housing of the transformer body by a connecting rod;

[0007] A support base is provided on the outer side and at the upper end of the support plate. The support base is a right-angle frame structure, and an arc-shaped bend is provided at the outer corner of the support base.

[0008] A cable tie holder is fixed on the outer wall of the support base. The cable tie holder has a cable tie hole that penetrates its interior at a position perpendicular to the horizontal plane. The positions of the cable tie hole and the lead wire hole are set one-to-one.

[0009] In detail, a support rod is provided above the support base, and the support rods are symmetrically distributed along both ends of the support base. The lower end of the support rod is fixed to the surface of the support base by screws, and the same top plate is fixed above the two support rods.

[0010] In detail, the surface of the support rod is slidably fitted with a limiting sleeve, and a pressure plate is fixed on the outer ring wall of the limiting sleeve by a bracket. The pressure plate is provided with teeth below it, and there are several groups of teeth, which correspond one-to-one with the positions of the lead holes.

[0011] In detail, a threaded sleeve is provided through the surface of the top plate, and the connection between the threaded sleeve and the top plate is fixed by welding. A threaded rod is provided through the inside of the threaded sleeve and threaded, and a handle is fixed at the upper end of the threaded rod.

[0012] In detail, a bearing is provided at the center of the upper end of the pressure plate, and the lower end of the bearing is fixedly assembled to the surface of the pressure plate by screws. The lower end of the threaded rod is inserted into the interior of the bearing, and the surface of the threaded rod is interference-fitted with the inner ring wall of the bearing.

[0013] In detail, a winding roller is provided below the support base, and roller seats are fixedly sleeved at both ends of the winding roller. The outer ring wall of the roller seat is fixedly assembled to the surface of the support plate through the bracket. The winding roller has a structure that is wide at both ends and narrow in the middle, and its wide end is covered with an arc-shaped cover.

[0014] In detail, threaded posts are fixed on both sides of the winding roller, and an inner sleeve is provided through the surface of the arc-shaped cover. The inner sleeve and the threaded posts are interpenetrating each other. The ends of the threaded posts are threadedly connected with threaded caps, and one end of the threaded cap is tightly abutted against the end face of the inner sleeve.

The positions of the wire bundle sleeve, the winding roller, and the wire bundle hole are arranged in a one-to-one correspondence. The outer wall surface of the wire bundle sleeve is fixedly assembled with the surface of the support plate through a bracket.

[0016] The design scheme proposed in this utility model has the following beneficial effects in application:

[0017] 1. After connecting the wires to the terminals through the lead-in holes on the support plate, the wires can be led out through the lead-in holes for wire bundling. The wires go completely downwards through the arc-shaped bend of the support base and are then led out downwards through the wire bundling holes. If some wires are too long, they can be partially wound around the winding roller and covered by the arc-shaped cover to prevent the wires from becoming loose. Finally, the wires are led out through the wire bundling sleeve to complete the overall wire bundling operation.

[0018] 2. To prevent the wires and terminals from pulling during the wiring process, the threaded rod is rotated by the handle, so that the threaded rod and the threaded sleeve are threaded together. This allows the threaded rod to rotate stably based on the bearing and move downward. The limiting sleeves and support rods at both ends of the pressure plate slide up and down, allowing the pressure plate with teeth to squeeze and engage with the wires passing under the teeth. This creates an anti-pull-out effect and improves the stability of the power supply between the wires and terminals during the wiring process. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-4 A cable harness structure for a transformer includes a base 1, a transformer body 11 fixed above the base 1, terminals 12 fixedly distributed above the transformer body 11, extension seats 13 respectively provided on both sides of the base 1, the extension seats 13 slidingly inserted into the base 1 and the connection position of the extension seats 13 and the base 1 is fixed by screws, a support plate 14 is provided above the extension seats 13, the surface of the support plate 14 is provided with lead wire holes 15, the positions of the lead wire holes 15 and the terminals 12 are one-to-one, the support plate 14 is located on one side of the transformer body 11 and is fixedly assembled with the housing of the transformer body 11 by a connecting rod 16;

[0026] A support base 17 is provided on the outer side and at the upper end of the support plate 14. The support base 17 is a right-angle frame structure. An arc-shaped bend 18 is provided at the outer corner of the support base 17. The arc-shaped bend 18 can avoid damage to the line caused by conventional sharp corners when the line is bent.

[0027] A cable tie seat 19 is fixed on the outer wall of the support base 17. The cable tie seat 19 has a cable tie hole 110 that passes through it at a position perpendicular to the horizontal plane. The positions of the cable tie hole 110 and the lead wire hole 15 are arranged one-to-one.

[0028] It should be further noted that a support rod 1001 is provided above the support base 17. The support rods 1001 are symmetrically distributed along both ends of the support base 17. The lower end of the support rod 1001 is fixed to the surface of the support base 17 by screws. The same top plate 1002 is fixed above the two support rods 1001.

[0029] It should be further explained that the surface of the support rod 1001 is slidably fitted with the limiting sleeve 1003. The outer ring wall of the limiting sleeve 1003 is fixed with a pressure plate 1004 by a bracket. The pressure plate 1004 is provided with teeth 1005 below it. There are several groups of teeth 1005, and they correspond one-to-one with the positions of the lead hole 15. The teeth 1005 can move downward and cooperate with the upper end of the support base 17 to squeeze and bite the passing wire. This can prevent the wire from being pulled and broken at the connection point after it is connected to the terminal 12 due to wire bundling or subsequent use.

[0030] It should be further explained that a threaded sleeve 1007 is provided through the surface of the top plate 1002. The connection between the threaded sleeve 1007 and the top plate 1002 is fixed by welding. A threaded rod 1008 is provided through the inside of the threaded sleeve 1007 and threaded. A handle 1009 is fixed to the upper end of the threaded rod 1008. By holding the handle 1009, the threaded rod 1008 can be rotated, so that the threaded rod 1008 can move threadedly relative to the threaded sleeve 1007.

[0031] It should be further explained that a bearing 1006 is provided at the upper center of the pressure plate 1004. The lower end of the bearing 1006 is fixedly assembled to the surface of the pressure plate 1004 by screws. The lower end of the threaded rod 1008 is inserted into the interior of the bearing 1006, and the surface of the threaded rod 1008 is interference-fitted with the inner ring wall of the bearing 1006. The threaded rod 1008 can rotate based on the bearing 1006, and can also move threadedly with the threaded sleeve 1007 to ensure the stability of the structural linkage.

[0032] It should be further explained that a winding roller 21 is provided below the support base 17. Roller seats 2 are fixedly sleeved at both ends of the winding roller 21. The outer ring wall of the roller seat 2 is fixedly assembled to the surface of the support plate 14 through the bracket. The winding roller 21 has a structure that is wide at both ends and narrow in the middle. Its wide end is covered with an arc-shaped cover 25. The winding roller 21 can wind and roll up the excess length of the wire during the wire bundling process. The coverage of the arc-shaped cover 25 prevents the wire from becoming too loose after winding.

[0033] It should be further explained that threaded posts 23 are fixed on both sides of the winding roller 21, and an inner sleeve 22 is provided through the surface of the arc-shaped cover 25. The inner sleeve 22 and the threaded posts 23 are mutually connected. The end of the threaded post 23 is threadedly connected to a threaded cap 24. One end of the threaded cap 24 is tightly abutted against the end face of the inner sleeve 22. When the arc-shaped cover 25 needs to be installed, the arc-shaped cover 25 is fitted with the winding roller 21, which can realize the through connection between the threaded post 23 and the inner sleeve 22. Through the mutual threaded connection between the threaded cap 24 and the threaded post 23, the arc-shaped cover 25 can stably cover the winding roller 21. The arc-shaped cover 25 has a semi-circular structure.

[0034] It should be further explained that a wire harness sleeve 3 is provided below the winding roller 21. The positions of the wire harness sleeve 3, the winding roller 21 and the wire harness hole 110 are arranged in a one-to-one correspondence. The outer wall of the wire harness sleeve 3 is fixedly assembled to the surface of the support plate 14 through the bracket. By corresponding the positions of the wire path, the bending loss of the wire is reduced during the wire harnessing process.

[0035] Working method: After connecting the wire to the terminal block 12 through the lead wire hole 15 on the support plate, the wire can be led out from the lead wire hole 15 for wire bundling. The wire goes down completely through the arc bend 18 of the support base 17 and is led out downward through the wire bundling hole 110. If part of the wire is too long, it can be wound on the winding roller 21 for partial winding and covered by the arc cover 25 to prevent the wire from becoming loose. Finally, it is led out through the wire bundling sleeve 3 to complete the overall wire bundling operation.

[0036] When the arc-shaped cover 25 needs to be installed, the arc-shaped cover 25 is fitted with the winding roller 21, which can achieve the through-setting of the threaded column 23 and the inner sleeve 22. Through the mutual threaded connection of the threaded cap 24 and the threaded column 23, the arc-shaped cover 25 and the winding roller 21 can be stably covered. The arc-shaped cover 25 has a semi-circular structure.

[0037] To prevent the wires from pulling on the terminals 12 during the wiring process, the threaded rod 1008 is rotated by the handle 1009, so that the threaded rod 1008 and the threaded sleeve 1007 are threadedly aligned. This allows the threaded rod 1008 to rotate stably based on the bearing 1006 and move downward. The limiting sleeves 1003 at both ends of the pressure plate 1004 and the support rod 1001 slide up and down, allowing the pressure plate 1004 with teeth 1005 to squeeze and engage with the wires passing under the teeth 1005. This creates an anti-pull-out effect and improves the stability of the power supply between the wires and terminals 12 during the wiring process.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
