Description

Technical Field

[0001] This utility model relates to the field of wire harness technology, and in particular to a wire harness with a built-in skeleton to resist bending. Background Technology

[0002] A wire harness is an electrical connection component primarily used to transmit electrical energy, signals, and data in various mechanical equipment and electrical facilities. It bridges the gap between two or more isolated electronic circuits, allowing current to flow and enabling the various functions of electronic components. A wire harness typically consists of basic parts such as wires, terminals, and plastic parts; more complex harnesses may also include tape, cable ties, sleeves, sheaths, and labels.

[0003] When using wire harnesses for circuit connections, the terminals at both ends of the wire harness need to be inserted into the slots on the two devices respectively. During daily use, the surface of the wire harness is stretched and bent, which will put tension on the terminals at both ends and cause the connection between the wire harness and the terminals to deflect too much, making the connection between the wire harness and the terminals loose, causing the wire harness to break or fall out of the terminals, thus affecting the normal use of the wire harness. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that when the surface of the wire harness is stretched and bent during daily use, it will cause tension on the terminals at both ends and cause the connection between the wire harness and the terminal to deflect too much, resulting in loosening of the connection between the wire harness and the terminal, causing the wire harness to break or fall out of the terminal, thus affecting the normal use of the wire harness. Therefore, a wire harness with built-in skeleton anti-bending is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wire harness with a built-in skeleton for bending resistance, comprising a wire body, the wire body being composed of several lines, and terminal shells being provided at both ends of the wire body, the outer surface of the terminal shells being provided with a protective device that can protect and reinforce the outer side of the connection between the wire body and the terminal shells.

[0006] The effect achieved by the above components is that when using the cable, the terminal shells at both ends of the cable are connected to the slots of the equipment, and circuit transmission is provided through the cable.

[0007] Preferably, the protective device includes a rectangular frame, one side of which is fixedly connected to one side of the terminal housing. Two grooved rods are fixedly connected to the end of the rectangular frame away from the terminal housing. A sliding rod is slidably connected to the inner wall of the grooved rod. A square frame is fixedly connected to one end of the sliding rod. A T-shaped rod is fixedly connected to one side of the sliding rod. A U-shaped block is slidably connected to the outer surface of the T-shaped rod. The U-shaped block is an elastic metal block. The two ends of the U-shaped block are close together towards the middle. A spring is provided on one side of the U-shaped block. The two ends of the spring are fixedly connected to one side of the U-shaped block and one end of the T-shaped rod, respectively.

[0008] The effect achieved by the above components is as follows: By setting up the frame, when installing the wire harness, the two ends of the wire harness can be pinched against the outer surface of the elastic U-shaped blocks on one side of the two sliding rods near the terminal housing. This controls the two ends of the U-shaped blocks to expand outward and move away from the slot rod while compressing the spring. Then, the frame is pushed to control the two sliding rods to slide on the inner wall of the slot rod, adjusting the distance between the frame and the rectangular frame, changing the total length of the sliding rod and the slot rod to a suitable length. Then, the U-shaped blocks are released, and the spring pushes the U-shaped blocks to slide on the outer surface of the T-shaped rod towards the slot rod, pressing one side of the U-shaped blocks against the outer surface of the slot rod, and causing the two ends of the U-shaped blocks to move towards the middle through elastic deformation, pressing against the upper and lower sides of the slot rod. This fixes the position of the sliding rod and the frame. When the wire harness is in use, the rectangular frame, slot rod, sliding rod, and frame can protect the outer side of the wire near the terminal housing, minimizing the risk of the wire near the terminal housing bending, which could lead to loosening of the connection between the wire harness and the terminal, causing the wire harness to break or fall out of the terminal.

[0009] Preferably, the upper and lower ends of the sliding rod are respectively fixedly connected to diagonal rods, and the end of the diagonal rod away from the sliding rod is fixedly connected to one side of the frame.

[0010] The effect achieved by the above components is that by setting diagonal braces, the connection between the sliding rod and the frame can be strengthened, thereby improving the structural stability of the connection between the sliding rod and the frame.

[0011] Preferably, the upper and lower sides of the U-shaped block are respectively fixedly connected with protrusions, and one edge of the protrusion is a bevel.

[0012] The effect achieved by the above components is that by pressing the inclined surface of the outer surface of the protrusion with your hand, you can more easily push the two ends of the U-shaped block outward and control the movement of the U-shaped block on the outer surface of the T-shaped rod.

[0013] Preferably, a limiting component is provided inside the frame. The limiting component includes several support rods, one end of each support rod is fixedly connected to the four corners of the inner wall of the frame, and a rubber sleeve is fixedly connected to the ends of each support rod that are close to each other.

[0014] The effect achieved by the above components is that when the mutual angle between the wire and the terminal shell is limited by the protective device, the wire located inside the frame will be inside the rubber sleeve. The rubber sleeve can further limit the position of the wire and avoid the wire from sliding and shifting and folding as much as possible.

[0015] Preferably, a positioning device is provided at the top of the frame. The positioning device includes a bolt rectangular rod. The bottom end of the rectangular rod is fixedly connected to the top of the frame. A bolt is rotatably connected to the bottom of the inner wall of the rectangular rod. A positioning rod is threadedly connected to the outer surface of the bolt. One end of the positioning rod slides on one side of the rectangular rod.

[0016] The effect achieved by the above components is as follows: when the installation line is protected on the outside of the line by the protective device, the excess length of the line can pass through the top of the frame and the positioning rod. By rotating the bolt, the positioning rod is controlled to move downward on the outer surface of the bolt and one side of the rectangular rod, pressing the positioning rod on the outer surface of the line body. This restricts the position of the excess part of the line body on the outside of the frame, and avoids the excess part of the line body from protruding as much as possible. This further prevents the line body from being pulled and causing the connection with the terminal shell to loosen.

[0017] Preferably, one end of the positioning rod is fixedly connected to two L-shaped blocks, and one side of the L-shaped blocks slides on the outer surface of the rectangular rod.

[0018] The effect achieved by the above components is that when the rotating bolt controls the positioning rod to move up and down, the two L-shaped blocks at one end of the positioning rod will slide on the outer surface of the rectangular rod. The L-shaped blocks can further limit the angle between the positioning rod and the rectangular rod, and avoid the angle of the two ends of the positioning rod from deviating as much as possible.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this utility model, by setting up a protective device, and by placing the rectangular frame, groove rod, sliding rod and square frame on the outside of the wire body, the outer side of the wire body near the terminal shell is protected, so as to avoid the wire body near the terminal shell from bending, which would cause the connection between the wire harness and the terminal to loosen, resulting in the wire harness breaking or falling out of the terminal.

Detailed Implementation

[0026] Example 1, as Figure 1-3 As shown, a wire harness with built-in skeleton for bending resistance includes a wire body 1, which is composed of several lines. Terminal shells 4 are respectively provided at both ends of the wire body 1. A protective device 2 is provided on the outer surface of the terminal shells 4 to protect and reinforce the outside of the connection between the wire body 1 and the terminal shells 4.

[0027] Reference Figure 2-3 As shown in this embodiment: the protective device 2 includes a rectangular frame 21. One side of the rectangular frame 21 is fixedly connected to one side of the terminal housing 4. Two grooved rods 22 are fixedly connected to the end of the rectangular frame 21 away from the terminal housing 4. A sliding rod 23 is slidably connected to the inner wall of the grooved rod 22. A square frame 24 is fixedly connected to one end of the sliding rod 23. A T-shaped rod 25 is fixedly connected to one side of the sliding rod 23. A U-shaped block 27 is slidably connected to the outer surface of the T-shaped rod 25. The U-shaped block 27 is an elastic metal block. The two ends of the U-shaped block 27 move towards the middle. A spring 26 is provided on one side of the U-shaped block 27. The two ends of the spring 26 are fixedly connected to one side of the U-shaped block 27 and one end of the T-shaped rod 25, respectively. By setting the square frame 24, when installing the wire harness, the two ends of the wire harness can be pinched against the outer surface of the elastic U-shaped block 27 on one side of the two sliding rods 23 near the terminal housing 4, controlling the two ends of the U-shaped block 27 to expand outward and move away from the grooved rod 22 while compressing the spring 26, and then pushing... The movable frame 24 controls the two sliding rods 23 to slide on the inner wall of the groove rod 22, adjusting the distance between the frame 24 and the rectangular frame 21, changing the total length of the sliding rod 23 and the groove rod 22 to a suitable length. Then, the U-shaped block 27 is released, and the spring 26 pushes the U-shaped block 27 to slide on the outer surface of the T-shaped rod 25 towards the groove rod 22, pressing one side of the U-shaped block 27 against the outer surface of the groove rod 22, and causing the two ends of the U-shaped block 27 to move towards the middle through elastic deformation, pressing against the upper and lower sides of the groove rod 22, thus fixing the position of the sliding rod 23 and the frame 24. When the wire harness is in use, the terminal shells 4 at both ends of the wire body 1 are connected to the slot of the equipment, and the wire body 1 provides circuit transmission. The rectangular frame 21, the groove rod 22, the sliding rod 23 and the frame 24 can protect the outer side of the wire body 1 near the terminal shell 4, avoiding the wire body 1 from bending near the terminal shell 4 as much as possible, which could cause the connection between the wire harness and the terminal to loosen, resulting in the wire harness breaking or falling out of the terminal.

[0028] Reference Figure 2-3As shown in this embodiment: the upper and lower ends of the sliding rod 23 are respectively fixedly connected with inclined rods 29. The end of the inclined rod 29 away from the sliding rod 23 is fixedly connected to one side of the frame 24. By setting the inclined rod 29, the connection between the sliding rod 23 and the frame 24 can be reinforced, and the stability of the connection structure between the sliding rod 23 and the frame 24 can be improved. The upper and lower sides of the U-shaped block 27 are respectively fixedly connected with protrusions 210. One edge of the protrusion 210 is a slope. By pressing the slope of the outer surface of the protrusion 210 with your hand, it is easier to push the two ends of the U-shaped block 27 outward and control the movement of the U-shaped block 27 on the outer surface of the T-shaped rod 25.

[0029] Reference Figure 2-3 As shown in this embodiment: a limiting component 28 is provided inside the frame 24 to further restrict the position of the wire 1. The limiting component 28 includes several support rods 281. One end of each support rod 281 is fixedly connected to the four corners of the inner wall of the frame 24. A rubber sleeve 282 is fixedly connected to the end of each support rod 281 that is close to each other. When the protective device 2 restricts the mutual angle between the wire 1 and the terminal shell 4, the wire 1 located inside the frame 24 will be inside the rubber sleeve 282. The rubber sleeve 282 can further restrict the position of the wire 1 and avoid the wire 1 from sliding and shifting and folding as much as possible.

[0030] Reference Figure 1-4 As shown in this embodiment: a positioning device 3 is provided at the top of the frame 24. The positioning device 3 includes a bolt 32 and a rectangular rod 31. The bottom end of the rectangular rod 31 is fixedly connected to the top of the frame 24. The bottom end of the inner wall of the rectangular rod 31 is rotatably connected to the bolt 32. The outer surface of the bolt 32 is threadedly connected to a positioning rod 33. One end of the positioning rod 33 slides on one side of the rectangular rod 31. When the installation line 1 is protected by the protective device 2, the excess length of the line 1 can be passed between the top of the frame 24 and the positioning rod 33. Rotating the bolt 32 controls the positioning rod 33 to move downward on the outer surface of the bolt 32 and one side of the rectangular rod 31, thus positioning the rod 33. 3. Pressing on the outer surface of the wire body 1 restricts the position of the excess part of the wire body 1 outside the frame 24, and avoids the excess part of the wire body 1 from protruding as much as possible. This further prevents the wire body 1 from being pulled and causing the connection with the terminal shell 4 to loosen. One end of the positioning rod 33 is fixedly connected to two L-shaped blocks 34. One side of the L-shaped block 34 slides on the outer surface of the rectangular rod 31. When the positioning rod 33 is moved up and down by rotating the bolt 32, the two L-shaped blocks 34 at one end of the positioning rod 33 will slide on the outer surface of the rectangular rod 31. The L-shaped blocks 34 can further restrict the angle between the positioning rod 33 and the rectangular rod 31, and avoid the angle of the two ends of the positioning rod 33 from deflecting as much as possible.

[0031] Working principle: When installing the wire harness, pinch the outer surface of the elastic U-shaped blocks 27 on one side of the two sliding rods 23 at both ends of the wire harness near the terminal housing 4. Control the two ends of the U-shaped blocks 27 to expand outward and move away from the slot rod 22, while compressing the spring 26. Then push the square frame 24 to control the two sliding rods 23 to slide on the inner wall of the slot rod 22, adjust the distance between the square frame 24 and the rectangular frame 21, and change the total length of the sliding rods 23 and the slot rod 22 to a suitable length. Then release the U-shaped blocks 27, and the spring 26 pushes the U-shaped blocks 27 to slide on the outer surface of the T-shaped rod 25 towards the slot rod 22, pressing one side of the U-shaped blocks 27 into the slot. The outer surface of the rod 22 and the two ends of the U-shaped block 27 are brought together by elastic deformation and pressed against the upper and lower sides of the groove rod 22. The position of the sliding rod 23 and the square frame 24 is fixed, and the excess length of the wire body 1 is passed through the top of the square frame 24 and the positioning rod 33. The bolt 32 is rotated to control the positioning rod 33 to move downward on the outer surface of the bolt 32 and one side of the rectangular rod 31, pressing the positioning rod 33 against the outer surface of the wire body 1. The position of the excess part of the wire body 1 outside the square frame 24 is restricted. When the wire harness is used, the rectangular frame 21, the groove rod 22, the sliding rod 23 and the square frame 24 protect the outer side of the wire body 1 near the terminal shell 4.
