Description

Technical Field

[0001] This utility model relates to the field of cable fixing technology, and in particular to a high-voltage wire harness assembly fixing structure. Background Technology

[0002] High-voltage lines typically refer to power transmission lines that transmit voltages of 10kV or higher. They are widely used in the industrial sector. When supplying power to large equipment, they are usually composed of multiple wires. By binding multiple single wires together and then transforming the voltage using a transformer, the effect of high-voltage power transmission can be achieved.

[0003] However, traditional cable assembly and fixing is done by using cable ties to bind multiple cables together. Because the cables are mixed together, it is difficult to distinguish the source and direction of each cable. This will cause some trouble for maintenance personnel during maintenance, which is not only not conducive to subsequent maintenance, but also affects the overall aesthetics.

[0004] For example, when the power supply is connected to the line, the wire harness is fixed by bundling. When troubleshooting the circuit, it is difficult to distinguish the connection point and direction of each cable, which causes some trouble for maintenance. In addition, the bundling method can cause some twisting, which can easily lead to cracks in the outer insulation layer of the cable. Utility Model Content

[0005] This utility model discloses a high-voltage wire harness assembly and fixing structure, which aims to solve the technical problem that traditional cable assembly and fixing is done by using cable ties to fix multiple cables together. This fixing method makes it difficult to distinguish the source and direction of each cable because they are mixed together, which causes trouble for maintenance personnel during maintenance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-voltage wire harness assembly fixing structure includes an upper fixing seat and telescopic rods fixedly connected to its four bottom corners. A lower fixing seat is fixedly connected to the bottom end of the telescopic rod. A wire hole is opened in the middle of the upper fixing seat and the lower fixing seat. Sliding grooves are opened on the left and right sides of the wire hole. The structure also includes a fixing mechanism: the fixing mechanism includes a threaded seat fixedly connected to the front side of the upper fixing seat. A lead screw is threadedly connected inside the threaded seat. An arc-shaped piece is rotatably connected to the rear end of the lead screw. Slider blocks are fixedly connected to the left and right sides of the arc-shaped piece. A front gasket is fixedly connected to the rear side of the arc-shaped piece. A rear gasket is provided on the rear side of the front gasket.

[0008] Connection mechanism: The fixing mechanism is fixedly connected to the left and right sides of the upper fixing seat.

[0009] In this solution, a fixing mechanism can secure individual wires of different sizes. By rotating the lead screw and utilizing its threaded engagement with the threaded seat, the lead screw is driven to move back and forth along the slide groove, thereby transmitting the linear motion of the lead screw to the arc-shaped plate. This forces the arc-shaped plate to move back and forth within the wire hole. Through the sliding engagement of the sliders on the left and right sides of the arc-shaped plate with the slide grooves on the left and right sides of the wire hole, it is ensured that the arc-shaped plate can only move stably back and forth along a preset path, preventing it from deflecting or getting stuck. The front pad on the rear side of the arc-shaped plate contacts the wire passing through the wire hole and drives the wire to move backward to contact the rear pad. The clamping force of the two firmly presses the wire and fixes it within the wire hole. The shape of the arc-shaped plate helps to accommodate wires of different diameters and provides uniform clamping force.

[0010] In a preferred embodiment, the connecting mechanism includes a card holder fixedly connected to the right side of the upper fixed seat, buttons slidably connected to the front and rear sides of the card holder, a card block provided on the left side of the card holder, a spring provided inside the card block, and fixing pins slidably connected to the front and rear sides of the card block.

[0011] Multiple structures can be interconnected through a connecting mechanism to form a fixed assembly. This is achieved by inserting a locking block into the corresponding slot of an adjacent fixed structure. Under the action of a spring inside the locking block, the fixing pin engages in the slot, locking the structure in place. Pressing the buttons on the front and back sides of the slot overcomes the spring force, causing the fixing pin to retract inward and release the lock. This spring-loaded, button-unlocked fixing pin design enables quick, one-handed connection and separation between two fixed structures, greatly improving installation efficiency and convenience, and facilitating modular installation, disassembly, and maintenance.

[0012] As described above, a high-voltage wire harness assembly and fixing structure includes an upper fixing seat and telescopic rods fixedly connected to its four bottom corners. A lower fixing seat is fixedly connected to the bottom end of each telescopic rod. A wire hole is formed in the middle of both the upper and lower fixing seats, and sliding grooves are formed on both sides of the wire hole. The structure also includes: a fixing mechanism: the fixing mechanism includes a threaded seat fixedly connected to the front side of the upper fixing seat, a lead screw threadedly connected inside the threaded seat, an arc-shaped piece rotatably connected to the rear end of the lead screw, sliders fixedly connected to the left and right sides of the arc-shaped piece, a front washer fixedly connected to the rear side of the arc-shaped piece, and a rear washer provided behind the front washer; and a connecting mechanism: the fixing mechanism is fixedly connected to the left and right sides of the upper fixing seat. The high-voltage wire harness assembly and fixing structure provided by this utility model has the technical advantages of freely combinable fixing groups, clearly defined sequence of multiple lines, and convenient subsequent troubleshooting and maintenance.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] The high-voltage cable harness combination fixing structure disclosed in this utility model is mainly used in scenarios where multiple cables are constrained and fixed for high-voltage power transmission.

[0021] Reference Figure 1 , Figure 2 and Figure 3A high-voltage wire harness assembly fixing structure includes an upper fixing seat 1 and telescopic rods 2 fixedly connected to the four corners of its bottom. The bottom end of the telescopic rods 2 is fixedly connected to a lower fixing seat 3. A wire hole 4 is opened in the middle of the upper fixing seat 1 and the lower fixing seat 3. Sliding grooves 5 are opened on the left and right sides of the wire hole 4. The structure also includes: a fixing mechanism: the fixing mechanism includes a threaded seat 6 fixedly connected to the front side of the upper fixing seat 1. A lead screw 7 is threadedly connected inside the threaded seat 6. An arc-shaped piece 8 is rotatably connected to the rear end of the lead screw 7. Slider blocks 9 are fixedly connected to the left and right sides of the arc-shaped piece 8. A front gasket 10 is fixedly connected to the rear side of the arc-shaped piece 8. A rear gasket 11 is provided on the rear side of the front gasket 10. A connecting mechanism: the fixing mechanism is fixedly connected to the left and right sides of the upper fixing seat 1.

[0022] Specifically, by rotating the lead screw 7, and utilizing its threaded engagement with the threaded seat 6, the lead screw 7 is driven to move back and forth along the slide groove 5, thereby transmitting the linear motion of the lead screw 7 to the arc-shaped piece 8, forcing the arc-shaped piece 8 to move back and forth within the wire hole 4. Through the sliding engagement of the sliders 9 on the left and right sides of the arc-shaped piece 8 with the slide grooves 5 on the left and right sides of the wire hole 4, it is ensured that the arc-shaped piece 8 can only move stably back and forth along the preset path, preventing it from deflecting or getting stuck. The front washer 10 on the rear side of the arc-shaped piece 8 contacts the wire passing through the wire hole 4, and drives the wire to move backward and contact the rear washer 11. The clamping force of the two firmly presses the wire and fixes it within the wire hole 4.

[0023] The arc-shaped piece 8 is set inside the wire hole 4, and the slider 9 is fixedly connected to the four corners of the front pad 10. The arc-shaped piece 8 is slidably connected to the slide groove 5 through the slider 9. The slider 9 restricts the arc-shaped piece 8 so that it can only move along the slide groove 5 in a certain direction, thus ensuring the accuracy of the fixation.

[0024] Among them, the rear gasket 11 is fixedly connected to the rear side inside the wire hole 4. The front gasket 10 and the rear gasket 11 are made of rubber. The rubber front gasket 10 and the rear gasket 11 form a soft clamp when fixed, reducing damage to the insulation layer on the surface of the wire. The front end of the lead screw 7 is provided with a cross groove, which makes it easy for the operator to rotate the lead screw 7.

[0025] Reference Figure 1 , Figure 4 and Figure 5 In a preferred embodiment, the connecting mechanism includes a card holder 12 fixedly connected to the right side of the upper fixed seat 1, buttons 13 slidably connected to the front and rear sides of the card holder 12, a card block 14 provided on the left side of the card holder 12, a spring 15 provided inside the card block 14, and fixing pins 16 slidably connected to the front and rear sides of the card block 14.

[0026] Specifically, by inserting the locking block 14 into the corresponding locking seat 12 of the adjacent fixing structure, the fixing pin 16 is locked into the locking seat 12 under the action of the spring 15 inside the locking block 14. Pressing the buttons 13 on the front and back sides of the locking seat 12 can overcome the elastic force of the spring 15 and drive the fixing pin 16 to retract inward, thus releasing the lock.

[0027] The locking block 14 is fixedly connected to the left side of the upper fixing seat 1. The locking block 14 and the locking seat 12 can fit together. The button 13 has a pin hole corresponding to the fixing pin 16 inside. The locking block 14 has a cavity inside. One end of the spring 15 is fixedly connected to the cavity inside the locking block 14, and the other end of the spring 15 is fixedly connected to the inside of the fixing pin 16. Through the design of the locking block 14 and the locking seat 12, multiple structures can be assembled according to the number of cables to achieve the effect of free combination and fixation.

[0028] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, the upper fixing seat 1 and the lower fixing seat 3 are identical in shape and size, and the fixing mechanism and connecting mechanism provided on the surface of the upper fixing seat 1 are also provided on the lower fixing seat 3.

[0029] Specifically, the cable is fixed in two places by the upper fixing seat 1 and the lower fixing seat 3 to ensure that the cable is in a straight position, avoid damage caused by cable bending, and facilitate the clearing of the line.

[0030] Working principle: In use, a single cable is passed through the wire holes 4 of the upper fixing seat 1 and the lower fixing seat 3, and the telescopic rod 2 is adjusted to a suitable length. The lead screw 7 is rotated using a tool, utilizing its threaded engagement with the threaded seat 6 to drive the lead screw 7 along the slide groove 5, causing the arc-shaped piece 8 to move back and forth within the wire hole 4. The front washer 10 on the rear side of the arc-shaped piece 8 contacts the wire passing through the wire hole 4, causing the wire to move backward and contact the rear washer 11. The clamping force of both firmly presses and fixes the wire within the wire hole 4. The shape of the arc-shaped piece 8 helps accommodate wires of different diameters. Provide uniform clamping force. After performing this operation on the lead screw 7 of the upper fixed seat 1 and the lower fixed seat 3, the single cable is fixed. After performing this operation on all cables in the cable harness group, insert the locking block 14 into the corresponding locking seat 12 of the adjacent fixing structure. Under the action of the spring 15 inside the locking block 14, the fixing pin 16 is locked into the locking seat 12, thus clearly fixing multiple cables into a cable group. Subsequently, the locking pin 16 can be released by pressing the buttons 13 on the front and rear sides of the locking seat 12 to overcome the elastic force of the spring 15 and drive it to retract inward. The device can then be removed and recycled.

[0031] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
