Description

Technical Field

[0001] This application relates to the field of fixing fixture technology, and in particular to a wire harness fixing fixture. Background Technology

[0002] Heat shrink tubing is a heat shrinkable sleeve made of polyolefin material. The outer layer is made of high-quality, soft cross-linked polyolefin material, and the inner layer is made of composite hot melt adhesive. The outer layer material has the characteristics of insulation, corrosion resistance, and wear resistance, while the inner layer has advantages such as low melting point, waterproof sealing, and high adhesion. It is widely used in wire connection, wire end treatment, solder joint protection, wire harness marking, and insulation protection of resistors and capacitors, providing external insulation protection for conductive parts. During the processing of wire harness products, after the heat shrink tubing is assembled with the wires and terminals, it needs to be baked in an oven to shrink the heat shrink tubing and tightly wrap around the connection between the wires and terminals, thereby achieving the purpose of insulation protection and mechanical reinforcement. To ensure the position of the heat shrink tubing and the wire is fixed, a clamp is needed to position the heat shrink tubing on the wire harness. Currently, most clamps for wire harness heat shrink tubing are custom-designed structures based on the wire diameter, and the clamping diameter of the clamp must be strictly matched with the outer diameter of the wire harness being fixed.

[0003] Because different specifications of wire harness products correspond to different wire diameters, and the clamping opening of the fixing clamp is a fixed size, the clamping opening cannot be adjusted during use. When the wire harness diameter is smaller than the clamp opening diameter, the wire harness cannot be securely fixed and is prone to wobbling; when the wire harness diameter is larger than the clamp opening diameter, it cannot be clamped properly. Therefore, for companies that produce wire harness products of various specifications, it is necessary to customize special clamps for each wire diameter, resulting in a wide variety of clamps and high costs.

[0033] With the development of the automotive wiring harness industry, the specifications of wiring harness products are becoming increasingly diverse, placing higher demands on the versatility and adjustability of processing fixtures. Although some fixtures achieve a certain degree of self-adaptive clamping through spring structures, most still suffer from shortcomings such as complex structures, non-adjustable tension, and inability to simultaneously accommodate multiple wire diameter specifications and achieve precise control of clamping force. Therefore, how to design a wiring harness tooling fixture that can adapt to multiple wire diameter specifications, has adjustable clamping force, and a compact structure to solve the problems of poor versatility, high switching costs, and non-adjustable clamping force of existing fixtures is a technical problem that urgently needs to be solved by those skilled in the art.

[0034] This application provides a technical solution for a wire harness fixing clamp. Based on this, it can be adapted to wire harnesses of various diameters, exhibiting good versatility. See below for details.

[0035] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0036] like Figures 1-3 As shown, the wire harness fixing clamp includes:

[0037] First clamping part 1;

[0038] The second clamping part 2 is disposed opposite to the first clamping part 1;

[0039] The guide rail section includes a guide rail 301 and an elastic member 302 located inside the guide rail 301.

[0040] The second clamping part 2 is fixed on the guide rail 301, and the first clamping part 1 is slidably disposed between the guide rail 301;

[0041] The guide rail 301 can move along the first direction A under the action of external force, and drive the second clamping part 2 away from the first clamping part 1, while deforming the elastic element 302.

[0042] After the external force is removed, the guide rail 301 moves along the second direction B under the restoring force of the elastic member 302, and drives the second clamping part 2 to approach the first clamping part 1 until the distance between the two reaches the preset clamping distance L.

[0043] The wire harness fixing clamp of this application can adapt to wire harnesses of different diameters and has the feature of elastic adaptive clamping. The specific principle is as follows: First, elastic displacement compensation. Elastic potential energy is stored between the clamping parts through the elastic element 302. When the external force is removed, the restoring force of the elastic element 302 pushes the guide rail and the second clamping part fixed thereon to move towards the first clamping part. When the wire harness is placed between the two clamping parts, the movement stroke of the second clamping part will naturally stop due to the obstruction of the wire harness. The elastic element 302 can retain a certain amount of compression, and the restoring force generated by this compression is converted into clamping force. The larger the diameter of the wire harness, the greater the amount of compression retained by the elastic element 302, and the clamping force is correspondingly enhanced, thereby achieving reliable fixing without damaging the wire harness. Second, the cooperation between the slidable clamping part (first clamping part 1) and the fixed clamping part (second clamping part 2). The first clamping part 1 is slidably disposed on the guide rail 301, and the second clamping part 2 is fixed on the guide rail 301. Under external force, the guide rail 301 moves the second clamping part 2 away from the first clamping part 1, i.e., it opens. After the external force is removed, the guide rail 301 moves the second clamping part 2 towards the first clamping part 1 until it contacts the wire harness. The final clamping distance automatically equals the outer diameter of the wire harness, requiring no manual measurement or adjustment. Third, the linear force and displacement characteristics of the elastic element 302. The greater the compression of the elastic element 302, the greater the restoring force. For thinner wire harnesses, the compression of the elastic element 302 is small, resulting in a gentle clamping force that avoids damage to the heat shrink tubing or core wire; for thicker wire harnesses, the compression of the elastic element 302 is large, resulting in a stronger clamping force that ensures the wire harness remains fixed. This characteristic allows the clamping force to automatically match the wire diameter, eliminating the need to replace the elastic element 302 or the clamp. In summary, this wire harness fixing clamp achieves adaptive clamping of any wire harness within a certain diameter range (e.g., from 1 mm to 10 mm) through active approach and passive stopping.

[0044] The wire harness fixing clamp of this application has the following characteristics: First, its high versatility reduces the variety of tooling. One clamp can cover multiple wire harnesses with a continuous diameter range, completely changing the traditional solution of using a dedicated clamp for each wire diameter, reducing tooling inventory and changeover time. Second, it features self-adaptive clamping for easy operation. Workers only need to place the wire harness and release external force; the clamp automatically clamps, eliminating the need for measurement or manual gap adjustment, significantly improving production efficiency. Third, the clamping force automatically matches the wire diameter, protecting the wire harness. Fine wires experience gentle force, avoiding damage; thicker wires receive reliable force, ensuring fixation. It is particularly suitable for heat shrink tubing positioning, ensuring that the wire harness does not shift or suffer excessive compression during the heat shrinking process.

[0045] It should be noted that deformation of the elastic element 302 refers to the application of an external force that causes the elastic element 302 to be in a non-free state, i.e., being stretched or compressed. In this application, deformation refers to elastic deformation. The elastic element 302 refers to a component that can undergo changes in shape or size under the action of an external force (such as stretching, compression, torsion, etc.) and can completely return to its original shape after the external force is removed.

[0046] Optionally, the elastic element 302 can be a spring or rubber, etc.

[0047] Optionally, the preset clamping distance L is 0 mm to 5 mm. This 0 mm to 5 mm range is compatible with most common specifications of electronic wire harnesses, automotive wire harnesses, and internal wiring in household appliances, meeting the needs of multi-variety, small-batch production. Furthermore, it achieves stepless clamping and zero-gap fit: when L reaches 0 mm, the two clamping parts can fit completely together, ensuring effective clamping even for wire harnesses with extremely small diameters (such as 0.1 mm thin wires), preventing loosening due to excessive gaps; simultaneously, the 0 mm limit position also prevents violent impacts when the clamps are fully closed under no-load conditions, reducing component wear. The 5 mm preset clamping distance avoids excessive compression damage to the wire harness: limiting the maximum distance to 5 mm means that for thicker wire harnesses with diameters exceeding 5 mm, the clamp will not force a tighter gap, thus preventing excessive compression and deformation of the heat shrink tubing or insulation layer, protecting the integrity of the wire harness. Improved positioning accuracy and heat shrinking effect: Precise control ensures the final distance between the two clamping parts is within 5mm after clamping, limiting the wire harness to a very small range of motion. This effectively prevents displacement due to thermal expansion or external disturbance during heat shrinking, ensuring accurate positioning and uniform shrinkage of the heat shrink tubing. For example, the preset clamping distance L can be 0 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, etc.

[0048] In some embodiments, the wire harness fixing clamp further includes a force-applying part located on top of the guide rail. This force-applying part applies external force to push the guide rail along a first direction A and compresses or stretches the elastic element 302. Thus, the force-applying part can act directly on the top of the guide rail, efficiently converting external force into linear motion of the guide rail and compression of the spring, eliminating the need for the operator to directly touch the clamping part or the spring, saving effort and ensuring safety. Furthermore, by controlling the stroke of the force-applying part (such as a bolt or handle), the distance by which the guide rail drives the second clamping part 2 away from the first clamping part 1 can be precisely adjusted, thereby accommodating the insertion space of wire harnesses of different diameters.

[0049] Optionally, the force-applying part can be a bolt or a press handle.

[0050] In some embodiments, the opposing sides of the first clamping part 1 and the second clamping part 2 in this wire harness fixing clamp are both arc-shaped clamping surfaces. This allows the arc-shaped clamping surfaces to better fit the circular wire harness, increasing the contact area, reducing local pressure, and preventing damage to the heat shrink tubing or core wire. It also avoids sharp edges contacting the wire harness, reducing friction and scratches, and ensuring the integrity of the wire harness insulation layer or heat shrink tubing.

[0051] In some embodiments, the opposing sides of the first clamping part 1 and the second clamping part 2 in this wire harness fixing fixture are both V-shaped clamping surfaces. Therefore, the V-shaped clamping surfaces can achieve self-centering and automatic alignment of circular wire harnesses of different diameters, improving positioning accuracy. It also avoids sharp edges contacting the wire harness, reducing friction and scratches, and ensuring the integrity of the wire harness insulation layer or heat shrink tubing.

[0052] In some embodiments, the opposing sides of the first clamping part 1 and the second clamping part 2 in this wire harness fixing clamp are both planar clamping surfaces. Thus, the planar clamping surfaces are suitable for flat or irregularly shaped wire harnesses, providing stable clamping.

[0053] In some embodiments, the wire harness fixing clamp includes two parallel and oppositely arranged guide rails 301, with a base plate at the bottom of each guide rail 301; the second clamping part 2 is fixedly installed on the lower side of the base plate. Thus, the two parallel guide rails 301 jointly constrain the sliding path of the first clamping part 1, avoiding deflection or jamming that may occur with a single guide rail, ensuring that the first clamping part 1 remains parallel and aligned with the second clamping part 2 during movement, resulting in a smoother and more reliable clamping action. Furthermore, the base plate connects the two guide rails 301 into a single frame, significantly improving the bending and torsional stiffness of the guide rails, effectively reducing deformation under spring force, and ensuring positioning accuracy and clamping consistency during long-term use.

[0054] Furthermore, the first clamping part 1 is slidably mounted across and on the two guide rails 301.

[0055] Preferably, two guide rails 301 are provided with a top plate 402 and a slider 303. The top plate 402 is fixed to the top of the two guide rails 301 and has threads, with a bolt 401 inside the threads. The slider 303 is slidably disposed on the two guide rails 301 and is located between the top plate 402 and the bottom plate. One end of the elastic element 302 abuts against the bottom plate, and the other end abuts against the slider 303. Thus, the threaded engagement has good self-locking characteristics, allowing the bolt 401 to remain in any position, thereby maintaining a stable preload setting value. It also allows adjustment of the initial preload of the elastic element 302, enabling the clamp to adapt to a wider range of wire diameters or change the default clamping force. Specifically, the bolt 401 is threadedly engaged with the top plate 402 at the top of the guide rail. By rotating the bolt 401, the extension length of the bolt 401 can be changed, thereby changing the travel space of the slider 303 and thus adjusting the clamping force of the elastic element 302. For example, by reducing the extension length of bolt 401 by rotating bolt 401, slider 303 can have more stroke, resulting in more stroke when elastic element 302 returns, thus reducing clamping force; conversely, increasing the extension length of bolt 401 increases clamping force. The clamping force range of this wire harness fixing clamp is adjustable, adapting to a wider range of wire diameters: the magnitude of the preload directly determines the initial clamping force between the two clamping parts when no external force is applied. Increasing the preload allows for clamping finer wire harnesses (avoiding loosening due to insufficient clamping force), while decreasing the preload is suitable for softer or more easily deformable wire harnesses, further widening the wire diameter adaptability range of the same clamp.

[0056] In some embodiments, the wire harness fixing clamp further includes a mounting base fixed to the rear side of the first clamping portion, for mounting the fixing clamp to an external tooling or workbench. This facilitates installation.

[0057] Optionally, the mounting base has two mounting slots, which can be U-shaped or oblong. See also Figure 4 The wire harness fixing clamp 8 can be installed on the tooling through the U-shaped groove, and the wire harness 6 and heat shrink tubing 7 are clamped and fixed by the wire harness fixing clamp 8.

[0058] The method of using the wire harness fixing clamp of this application includes the following steps:

[0059] Step 1: Without applying external force, the elastic element 302 is in a natural or slightly pre-compressed state, with the two clamping parts in contact or maintaining a very small gap, in a standby state;

[0060] Step 2: Apply external force, such as manually pressing or tightening the top bolt. The guide rail 301 moves along the first direction A, the second clamping part 2 moves away from the first clamping part 1, the elastic element 302 is compressed, the clamping jaws open, leaving space for inserting the wire harness;

[0061] Step 3: Place the wire harness into the opening area between the two clamping parts to complete the wire harness positioning;

[0062] Step 4: Remove external force. The restoring force of the elastic element 302 pushes the guide rail 301 to move along the second direction B, and the second clamping part 2 moves closer to the first clamping part 1, starting automatic clamping;

[0063] Step 5: The second clamping part 2 contacts the wire harness. The wire harness stops its continued movement, and the elastic element 302 stops rebounding, retaining a certain amount of compression. At this time, the clamping distance automatically equals the outer diameter of the wire harness, and a continuous clamping force is generated;

[0064] Step 6: After processing is complete, apply external force again to open the clamps, remove the wire harness, and complete the release.

[0065] The wire harness fixing clamp described in this application has the following characteristics: 1. Simple operation, no manual adjustment required: The entire process only requires three steps: "apply external force → insert the wire harness → remove external force". The clamp automatically completes the clamping, eliminating the need for operators to measure wire diameter or adjust gaps, significantly reducing the skill requirements. 2. Adaptive clamping, time-saving and efficient: The elastic element 302 automatically rebounds and drives the second clamping part 2 to move closer. The wire harness diameter determines the final clamping position, eliminating the need for repeated trial clamping or calibration. A single clamping operation can be completed within seconds, significantly improving production line efficiency. 3. Gentle and controllable clamping force, protecting the wire harness and heat shrink tubing: The amount of compression retained when the elastic element 302 stops rebounding is naturally determined by the wire diameter. Thinner wires require less clamping force, and thicker wires require more clamping force, avoiding damage to the wire core or indentation of the heat shrink tubing due to excessive clamping, while ensuring a secure and non-loose fixation. 4. No-load buffering to reduce impact on parts: In step one, the two clamping parts are in close contact or maintain a minimal gap, and the elastic element 302 is in a natural or slightly compressed state. This avoids rigid collisions when the clamp closes under no-load conditions, extending the service life of the clamping parts and guide rails. 5. Accurate positioning to improve heat shrinking process quality: The wire harness position remains consistent throughout the clamping process, and the clamping force remains stable during heat shrinking. This effectively prevents the heat shrink tubing from shifting due to thermal expansion or slight wire harness movement, ensuring dimensional accuracy and appearance quality after heat shrinking.
