Description

Technical Field

[0001] This utility model relates to the field of wire harness clamping technology, specifically a novel wire harness clamp. Background Technology

[0002] A wire harness is an electrical component with a specific function and structure, formed by combining multiple wires or cables and securing them with materials such as insulation, sheathing, and cable ties. Like the nervous system of the human body, it transmits current and signals in various electrical and electronic devices, connecting power sources, electrical components, and control devices to ensure the normal operation of the entire system.

[0003] However, existing technologies still have the following problems:

[0004] First, the stability of existing wire harness clamps needs improvement. Most do not have a spring structure, so when clamping the wire harness, the uneven force makes it impossible for the clamping blocks to apply pressure evenly. The wire harness is prone to local excessive or insufficient force, which can lead to loosening, displacement, and other problems, affecting the normal operation of the wire harness in the equipment. Furthermore, it is usually inconvenient to adjust the spacing of the clamping structure. When encountering wire harnesses that exceed the design range, they either cannot be clamped or will damage the wire harness after clamping.

[0005] First, existing wire harness clamps are generally not easy to splice. In the electrical installation of large equipment, multiple clamps need to be combined to fix the wire harness in an orderly manner. However, existing clamps cannot be spliced ​​and can only be used individually. This not only makes the installation process cumbersome, but also makes it difficult to ensure the overall neatness and stability of the wire harness, reducing work efficiency and wiring quality.

[0006] To address the aforementioned problems, the inventors have proposed a novel wire harness clamp to solve them. Utility Model Content

[0007] To address the issues of insufficient clamping stability and inconvenience in splicing wire harness holders, the purpose of this invention is to provide a novel wire harness holder.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a novel wire harness clamp, comprising a base plate, wherein a plurality of limiting posts are symmetrically fixed on the upper surface of the base plate, and a clamping frame is symmetrically fixed on the upper surface of the base plate. A lower bracket, an upper bracket, and an upper plate are slidably arranged within the clamping frame, and clamping blocks are symmetrically fixed on the opposite surfaces of the lower bracket and the upper bracket. A first spring is fixed between the lower surface of the lower bracket and the clamping frame, and a second spring is fixed between the upper bracket and the upper plate.

[0009] Preferably, a locking block is symmetrically fixed on one side of the base plate, and a locking frame is symmetrically fixed on the other side of the base plate. The upper surface of the locking frame is provided with a locking groove for use with the locking block, and the locking block and the corresponding locking groove are connected by bolts.

[0010] Preferably, two support plates are fixedly provided on one side of the clamping frame, and a threaded column is rotatably provided between the two support plates. A knob is rotatably provided on the upper surface of the upper support plate, and the lower end of the knob passes through the support plate and is fixedly connected to the threaded column. A lifting block is threadedly sleeved on the outer surface of the threaded column, and the lifting block is fixedly connected to the upper plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses five equally spaced first and second springs in each clamping frame to ensure that the lower and upper supports are evenly stressed when moving, thus ensuring that the clamping blocks clamp the wire harness uniformly and improving clamping stability. Furthermore, rotating the knob controls the screw thread to raise and lower the upper plate and upper support, making operation simple and flexible. It can be flexibly adjusted according to the thickness of the wire harness and the clamping force required. Although this adjustment structure is not essential for clamping, it greatly improves the adaptability of the clamp to different wire harnesses and broadens its application range.

[0013] 2. This utility model uses a design that combines a card block and a card frame with bolt connections, which facilitates the splicing of multiple clamps and allows for flexible combination according to actual needs, thereby improving the versatility and practicality of the clamps.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1-3As shown, this utility model provides a novel wire harness clamp, including a base plate 1. A clamping frame 2 is symmetrically fixed to the upper surface of the base plate 1. A lower support 21, an upper support 22, and an upper plate 23 are slidably arranged within the clamping frame 2. Clamping blocks 24 are symmetrically fixed to the opposing surfaces of the lower support 21 and the upper support 22. The clamping blocks 24 are made of an elastic material, such as silicone rubber. Silicone rubber has excellent flexibility, high and low temperature resistance, and insulation properties, allowing it to closely conform to the surface of the wire harness, providing a good clamping effect without damaging the insulation layer. Furthermore, the opposing surfaces of the two clamping blocks 24 have arc-shaped grooves. The clamping blocks 24, being made of an elastic material and having arc-shaped grooves, can closely conform to the shape of the wire harness, preventing damage during clamping. The elastic buffer prevents damage to the insulation layer. A first spring 25 is fixed between the lower surface of the lower support 21 and the clamping frame 2, and a second spring 26 is fixed between the upper support 22 and the upper plate 23. The first spring 25 and the second spring 26 are made of 65Mn spring steel. This type of steel has a high elastic limit, fatigue strength, and good heat treatment performance, and can maintain stable elasticity during long-term use. The upper surface of the upper bracket 22 is fixedly provided with a support column 27, and the upper end of the support column 27 passes through the upper plate 23 and is fixedly provided with a limiting block 28. There are five first springs 25 and five second springs 26 in one of the clamping frames 2, and the five first springs 25 and five second springs 26 are distributed at equal intervals. In the initial state, the lower bracket 21 is supported by the first spring 25 and is located in a relatively low position. The upper bracket 22 maintains a certain distance from the upper plate 23 under the action of the second spring 26. At this time, the opening between the two clamping blocks 24 is large, which is convenient for placing the wire harness. When the wire harness is placed in the arc groove of the two clamping blocks 24, even without operating the knob 32, the lower bracket 21 and the upper bracket 22 will move towards each other by relying on the elastic force of the first spring 25 and the second spring 26, so that the clamping blocks 24 of elastic material initially clamp the wire harness. This is the basic clamping function based on the spring's own restoring force.

[0021] A number of limiting posts 11 are symmetrically fixed on the upper surface of the base plate 1. The height of the limiting posts 11 can be designed according to the diameter range of common wire harnesses, and can be set to 10-15mm. This can effectively guide and constrain the wire harness without being too high and affecting the placement and operation of the wire harness. The number of limiting posts 11 symmetrically fixed on the upper surface of the base plate 1 can guide and constrain the direction of the wire harness. During the placement of the wire harness, the wire harness can be arranged along the path defined by the limiting posts 11 to ensure that the wire harness is in a relatively neat state before entering the clamping area, avoiding the wire harness from becoming messy and tangled, and providing convenience for subsequent accurate clamping. At the same time, the limiting posts 11 can also prevent the wire harness from undergoing large displacement on the base plate 1 to a certain extent, and help the entire clamping process to be more stable.

[0022] The clamping frame 2 has symmetrically arranged T-shaped grooves 29. Short T-shaped sliders 210 are symmetrically fixed on both sides of the lower bracket 21, and the short T-shaped sliders 210 are locked in the corresponding T-shaped grooves 29. Long T-shaped sliders 211 are symmetrically fixed on both sides of the upper bracket 22 and the upper plate 23, and the long T-shaped sliders 211 are locked in the corresponding T-shaped grooves 29. The short T-shaped sliders 210 of the lower bracket 21 and the long T-shaped sliders 211 of the upper bracket 22 and the upper plate 23 cooperate with the T-shaped grooves 29 to ensure the stability of the lower bracket 21, the upper bracket 22 and the upper plate 23 when sliding, prevent deviation and shaking, and ensure clamping accuracy.

[0023] Two support plates 3 are fixedly provided on one side of the clamping frame 2, and a screw post 31 is rotatably provided between the two support plates 3. A knob 32 is rotatably provided on the upper surface of the upper support plate 3, and the lower end of the knob 32 passes through the support plate 3 and is fixedly connected to the screw post 31. A lifting block 33 is threadedly sleeved on the outer surface of the screw post 31, and the lifting block 33 is fixedly connected to the upper plate 23. When it is necessary to precisely adjust the distance between the two clamping structures, the knob 32 is rotated, and the knob 32 drives the screw post 31 to rotate. Since the screw post 31 is threadedly sleeved with the lifting block 33, the rotation of the screw post 31 causes the lifting block 33 to move along the axial direction of the screw post 31. Since the lifting block 33 is fixedly connected to the upper plate 23, the upper plate 23 rises and falls accordingly. During the rise and fall of the upper plate 23, the second spring 26 is compressed or stretched, which drives the upper bracket 22 to move synchronously, thereby changing the distance between the two clamping blocks 24 and realizing the precise clamping of wire harnesses of different thicknesses.

[0024] A locking block 4 is symmetrically fixed on one side of the base plate 1, and a locking frame 41 is symmetrically fixed on the other side of the base plate 1. The upper surface of the locking frame 41 is provided with a locking groove 42 for use with the locking block 4. The locking block 4 and the corresponding locking groove 42 are connected by bolts. If multiple of these new wire harness clamps need to be spliced ​​together, the locking block 4 of one clamp can be aligned with the locking groove 42 on the locking frame 41 of another clamp, and then the locking block 4 and the locking groove 42 can be fixedly connected by bolts, thereby realizing the splicing of multiple clamps.

[0025] Working principle: In the initial state, the lower bracket 21 is supported by the first spring 25 and is located at a relatively low position. The upper bracket 22 maintains a certain distance from the upper plate 23 under the action of the second spring 26. At this time, the opening between the two clamping blocks 24 is large, which is convenient for placing the wire harness. When the wire harness is placed in the arc groove of the two clamping blocks 24, even without operating the knob 32, the lower bracket 21 and the upper bracket 22 will move towards each other by relying on the elastic force of the first spring 25 and the second spring 26, so that the clamping blocks 24 of elastic material initially clamp the wire harness. This is the basic clamping function based on the spring's own restoring force.

[0026] A number of limiting posts 11 symmetrically fixed on the upper surface of the base plate 1 can guide and constrain the direction of the wire harness. During the placement of the wire harness, the wire harness can be arranged along the path defined by the limiting posts 11 to ensure that the wire harness is in a relatively neat state before entering the clamping area, avoiding the wire harness from becoming messy and tangled, and providing convenience for subsequent accurate clamping. At the same time, the limiting posts 11 can also prevent the wire harness from undergoing large displacement on the base plate 1 to a certain extent, and help the entire clamping process to be more stable.

[0027] When it is necessary to precisely adjust the distance between the two clamping structures, turn the knob 32. The knob 32 drives the threaded rod 31 to rotate. Since the threaded rod 31 is threadedly connected to the lifting block 33, the rotation of the threaded rod 31 causes the lifting block 33 to move along the axial direction of the threaded rod 31. Since the lifting block 33 is fixedly connected to the upper plate 23, the upper plate 23 rises and falls accordingly. During the rising and falling process of the upper plate 23, the second spring 26 will be compressed or stretched, which will drive the upper bracket 22 to move synchronously, thereby changing the distance between the two clamping blocks 24 and achieving precise clamping of wire harnesses of different thicknesses.

[0028] If multiple of these new wire harness holders need to be spliced ​​together, the locking block 4 of one holder can be aligned with the slot 42 on the locking frame 41 of another holder, and then the locking block 4 and the slot 42 can be fixedly connected with bolts to achieve splicing of multiple holders.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
