Description

Technical Field

[0001] This utility model relates to the field of wire harness management and installation technology, and more specifically, to an adjustable cable management clamp for cables and wire harnesses. Background Technology

[0002] In industrial production and consumer applications, adjustable wire harness clips and mounting brackets are crucial components for ensuring orderly wiring and reducing the risk of malfunctions in scenarios such as cabinet cabling, robot joint wiring harness organization, automotive wiring harness fixing, experimental equipment wiring organization, and home appliance internal wiring harness layout. With the rapid development of industries such as intelligent manufacturing and automotive electrification, the wiring harness arrangement environment is becoming increasingly complex, placing higher demands on the comprehensive performance of wiring management devices. These devices not only need to meet the adaptation requirements of diverse wiring harness specifications but also need to cope with stringent operating conditions such as confined installation spaces, continuous vibration, high-frequency maintenance, and traceability management.

[0003] However, existing cable clips have the following problems when used: Existing devices are mostly of fixed specifications or have limited adjustment ranges, making them unable to flexibly adapt to wire harnesses of different diameters; their vibration resistance and anti-loosening performance are insufficient, and they are prone to gradual backsliding in vibration environments, leading to wire harness fixation failure; the maintenance process relies on special tools, making tool-free operation difficult and increasing the difficulty of high-frequency maintenance; the installation status lacks intuitive visual indicators, making it impossible to quickly determine whether the fixation is in place; at the same time, there is a lack of effective active limiting structures for the bending radius of the wire harness, which can easily cause stress concentration due to excessive bending, resulting in damage to the wire harness insulation layer and affecting the safety and lifespan of use, especially in complex scenarios where there is both confined space and vibration. In addition, given the rigid requirements for high-frequency maintenance efficiency and traceability management, existing wire clips and fixing bases generally suffer from problems such as low structural integration, a large number of components, and cumbersome assembly processes.

[0004] This invention can simultaneously achieve vibration resistance and prevent accidental loosening without limiting the radius of the wire harness, and can intuitively confirm the clamping tooth position and wire harness markings, thus improving the visibility of maintenance. Summary of the Invention

[0012] A further preferred embodiment: a movable limiting groove is provided in the middle of the slide rail, the movable limiting groove is slidably connected to the slider, a wedge is threadedly connected to the upper end of the slider, and screw holes are provided on the rear side of the upper end of the slider and the upper end of the wedge, and long screws are threadedly connected to the screw holes.

[0013] A further preferred embodiment: the bottom of the slider is threaded with a short screw, and the short screw is threadedly connected to the adapter block. Beneficial effects

[0014] 1. By setting up a cable management platform, slide rails, and sliders, the cable management platform provides a support area for the cable harness. Its sliding slot cooperates with the adapter block to adapt to different cable harness specifications and flexibly adjust the layout. The slide rails provide a moving track for the sliders. The internal teeth engage with the springs of the sliders to achieve micro-level positioning, so that the sliders are temporarily stable in a predetermined position. The sliders move freely in the slide rails through the springs. Tightening the screws can significantly increase the clamping force and achieve reliable self-locking. With the addition of a secondary locking tab, a mechanical secondary anti-reverse mechanism is formed, which effectively suppresses the backing caused by vibration, thermal expansion and contraction, etc. The three components work together to facilitate the installation, adjustment and maintenance of the cable harness, realize the operation process of cutting-free and repeatedly opening, and reliably limit the cable harness, reduce the risk of stress concentration and insulation layer damage, and improve the stability and flexibility of cable management. 2. Equipped with a slider, wedge, long screw, and secondary locking paddle, the slider achieves initial positioning through the engagement of a spring plate with the teeth of the slide rail. When the long screw is tightened, it drives the wedge to move forward, generating a wedge pressure that further presses the slider against the slide rail, significantly increasing the radial clamping force and achieving reliable self-locking. When the secondary locking paddle is moved to the locked position, its internal rectangular frame engages with the anti-reverse component, forming a mechanical secondary anti-reverse mechanism. This effectively suppresses gradual retraction caused by vibration and thermal expansion and contraction. During maintenance or adjustment, the secondary locking paddle is moved to the unlocked position, and the long screw is appropriately retracted to release the wedge pressure. The slider can then be pulled back to remove the wire harness, achieving a maintenance process that is cut-free and can be repeatedly opened, balancing the reliability of locking with the convenience of operation. 3. By setting up springs and slides, the semi-circular teeth inside the slides mesh with the elastic springs at both ends of the slider. The springs are elastic, allowing the slider to move freely within the slides. At the same time, it can temporarily stabilize when it reaches the designated position, providing a basis for subsequent locking operations. This structure not only ensures the flexibility of slider position adjustment, but also achieves micro-level positioning through the meshing of the teeth and springs, improving the accuracy of position control during cable management and laying a good foundation for subsequent reliable locking. 4. In summary, this adjustable cable management clamp for cables and wire harnesses, through its structure including a cable management platform, slide rails, sliders, secondary locking tabs, springs, wedges, and long screws, provides a foundation for supporting the wire harness and adapting to specifications. The slide rails, springs, and sliders work together to achieve micro-level positioning and flexible movement. The wedges and long screws significantly increase the radial clamping force through wedge pressure, achieving reliable self-locking. The secondary locking tabs form a mechanical secondary anti-reverse mechanism, effectively suppressing the risk of backlash. These structures work together to facilitate the installation, adjustment, and maintenance of the wire harness without cutting, while also providing stable positioning of the wire harness, reducing the risk of damage. It balances ease of operation, locking reliability, and usage flexibility, providing an efficient and reliable solution for cable and wire harness management. Attached Figure Description

[0021] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0022] Please see Figure 1-5In this embodiment of the present invention, an adjustable cable management clip for cables and wire harnesses includes: a base 1, a cable management platform 2 mounted on the upper end of the base 1, a slide rail 3 fixedly mounted on the upper end of the cable management platform 2, an adapter block 4 slidably connected to the middle of the cable management platform 2, a slider 5 slidably connected inside the slide rail 3, a secondary locking lever 6 slidably connected inside the slider 5, semi-circular teeth provided at both ends of the slide rail 3, and spring pieces 505 fixedly connected at both ends of the slider 5. The spring pieces 505 engage with the teeth in the slide rail 3 and are elastic. External recesses are provided at the top of both ends of the cable management platform 2, and internal recesses are provided at both ends of the slide rail 3. The groove fits into the recessed groove. Trapezoidal hooks 101 are fixedly connected to the bottom of both the front and rear ends of the base 1. A positioning post 102 is fixedly installed in the middle of the upper end of the base 1, and the positioning post 102 is embedded in the bottom of the cable tie 2. Mounting holes 103 are provided at the four corners of the upper end of the base 1. Buckles 201 are fixedly installed at the bottom of the front and rear ends of the cable tie 2, and the buckles 201 engage with the trapezoidal hooks 101. Trapezoidal hooks 202 are fixedly installed at the top of both the left and right ends of the cable tie 2, and the trapezoidal hooks 202 engage with the bottom of the slide rail 3. Buckles 301 are fixedly connected to the top of both the left and right ends of the slide rail 3, and the buckles 301 engage with the trapezoidal hooks 202. A mounting hole 103 is provided in the middle of the cable tie 2. A sliding slot 203 is provided, and the sliding slot 203 is slidably connected to the adapter block 4. A groove is provided at the bottom of the sliding slot 203. A slide rail is fixedly connected to the bottom of the adapter block 4, and the slide rail is slidably connected to the groove. The base 1 is composed of two cuboid plates, with four positioning posts 102 on its upper surface for connection to the four mounting holes at the bottom of the cable tie 2. Trapezoidal hooks 101 on both sides are used for connection to the clips 201 on the cable tie 2. The base 1 has four mounting holes 103 for fixing the base 1. The outer groove of the cable tie 2 is used to connect to the inner groove of the slide rail 3. The trapezoidal hooks 202 on the cable tie 2 are used to connect to the clips 301 on the slide rail 3. The sliding slot 203 in the middle of the cable tray 2 and the groove at the bottom inside are used to connect with the slide rail at the bottom of the adapter block 4. The slider 5 moves freely in the slide rail 3 through the circular spring piece 505. When it reaches the designated fixed position, the secondary locking tab 6 is pulled open, and then the connection is fixed by screws. When in use, the cable or wire harness is placed in the support area of ​​the clip cable tray 2, and the wire harness axis is roughly parallel to the slide rail direction. If corner wiring is required, a reasonable bending radius can be reserved according to the installation position. It is recommended to be 3-4 times larger than the outer diameter of the wire harness to reduce stress concentration and the risk of insulation damage. Push the slider 5 forward so that it moves forward in the slide rail 3 and the wire harness is covered and limited.At this point, the micro-gradient positioning formed by the lateral spring 505 and the tooth surface of the slide rail 3 temporarily stabilizes the slider 5 in the predetermined position. Tightening the screw further presses the slider 5 against the slide rail 3, significantly increasing the clamping force in the wire direction and achieving reliable self-locking. Moving the secondary locking lever 6 to the locked position causes the internal rectangular frame of the lever to engage with the anti-reverse component of the slider 5, forming a mechanical secondary anti-reverse mechanism to suppress gradual retraction caused by vibration, thermal expansion and contraction, etc. When unlocking, the operator moves the secondary locking lever 6 to the unlocked position and appropriately retracts the screw to release pressure. Following the guide of the slide rail 3, the operator manually pulls the slider 5 backward to create sufficient wire entry clearance. The lateral circular spring 505 of the slider 5 remains lightly pressed against the tooth surface, maintaining its position and preventing slippage. When maintenance or adjustment is required, the secondary locking lever 6 is moved to the unlocked position, the screw is appropriately retracted to release pressure, and then the slider 5 is pulled backward to remove the wire harness, achieving cut-free operation. For the reusable maintenance process, in terms of material selection, the base 1 and cable management platform 2 are preferably made of PA66+GF (glass fiber content 20%~35%), while the slide rail 3 and slider 5 are preferably made of POM or reinforced nylon to obtain low friction and wear resistance. The elastic part of the secondary locking lever 6 can be made of PA66 or POM, or the elastic spring of the lever can be made of SUS301 stainless steel insert. The tooth pitch of the slide rail 3 is preferably 1.2~2.0mm to balance fine adjustment accuracy and anti-backward performance. The free extension of the lateral spring 505 of the slider 5 is preferably 0.2~0.6mm to ensure that there is still elasticity after pressing into the tooth surface. The side clearance of the slide rail between the adapter block 4 and the cable management platform 2 is preferably 0.05~0.20mm to ensure smooth sliding and avoid vibration. A chamfer or R-angle of ≥0.5mm is set at the edge of the wire harness contact to avoid cutting the wire insulation. It is recommended that the tooth surface be treated with fine teeth and semi-polished to improve the meshing feel and reduce wear dust.

[0023] In this embodiment of the invention, a movable limiting groove 302 is provided in the middle of the slide rail 3. The movable limiting groove 302 is slidably connected to the slider 5. A wedge block 501 is threadedly connected to the upper end of the slider 5. Screw holes 502 are provided on the rear side of the upper end of the slider 5 and the upper end of the wedge block 501. A long screw 503 is threadedly connected to the screw hole 502. A short screw 504 is threadedly connected to the bottom of the slider 5. The short screw 504 is threadedly connected to the adapter block 4. The top of the adapter block 4 is connected to the slider 5 through the short screw 504. The device 5 moves freely on the slide rail of the slide 3 via the circular spring piece 505. When it reaches the designated fixed position, it pulls open the secondary locking piece 6 and uses the wedge block 501 and the long screw 503 to connect and fix it. During the retraction process, the long screw 503 is retracted appropriately to release the wedge pressure of the wedge block 501. In use, when the long screw 503 is tightened, the long screw 503 drives the wedge block 501 to move forward along the axial direction to generate a wedge pressure effect, which further presses the slider 5 against the slide rail 3, and the clamping force in the linear direction is significantly improved. The wedge structure converts the axial tightening force into a radial clamping force, achieving reliable self-locking. When the secondary locking lever 6 is moved to the locked position, the internal rectangular frame of the lever engages with the wedge block 501 or the anti-reverse component of the slider 5, forming a mechanical secondary anti-reverse mechanism. This suppresses gradual retraction caused by vibration, thermal expansion and contraction, etc. During maintenance or adjustment, the secondary locking lever 6 is moved to the unlocked position, and the long screw 503 is appropriately retracted to release the wedge pressure. Then, the slider 5 is pulled back to remove the wire harness, achieving cut-free and reusable operation. For the maintenance process of reopening, in terms of material selection, wedge 501 can be made of zinc alloy die casting or carbon steel with surface anti-rust treatment; for long screw 503, it is recommended to use stainless steel (A2-70 / A4-70) or galvanized carbon steel. The wedge angle of wedge 501 is preferably 60°~100°, and the wedge stroke is 2~6mm. The recommended operating torque for tightening long screw 503 is 0.2~0.6N·m (selected according to thread specifications and materials) to achieve stable clamping without damaging the threads of plastic parts or inserts.
