Description

Technical Field

[0001] This utility model relates to the field of wire connection technology, and in particular to a wire clamp that prevents loosening and vibration. Background Technology

[0002] Cable clamps are iron or aluminum metal accessories used to fix wires. Most of them need to withstand significant tensile forces during operation, and some also need to ensure good electrical contact. Existing cable clamps, due to their structural limitations and screw-based fixing, are prone to loosening during use, leading to cable or wire instability. Cable clamps are also easily displaced by vibration, affecting the fixing effect of cables or wires. For example, utility model patent CN212542730U discloses a torque-locking branch clamp, including a clamp body. One end of the clamp body has a main wire groove, and the other end has at least two wiring holes. A torque bolt is detachably connected to the end of the clamp body located in the main wire groove, and a torque-locking bolt connecting the wiring holes is detachably connected to the top of the other end; the diameters of the at least two wiring holes may be the same or different. While the above patented technology provides some convenience for disassembly and assembly and reliable connection, the wire's movement due to wind and micro-vibrations caused by electromagnetic effects can lead to bolt loosening, poor contact, and potential discharge that could burn out the main wire, posing a safety hazard. Therefore, it is necessary to develop a non-loosening and shockproof wire clamp to address the above-mentioned defects. Utility Model Content

The torsion spring passes through the pin. One side of the torsion spring is clamped on the upper end face of the first support leg, and the other side of the torsion spring is clamped on the side of the support.

[0008] Preferably, the first leg has an inverted "7" shape and the front end of the first leg has a serrated structure.

[0009] Preferably, a pressure rod is provided behind the threaded rod, the pressure rod is vertically slidably connected to the upper fixed seat and the wire clamp body, and a second spring is provided between the pressure rod and the upper fixed seat for pressing; the inner end of the pressure rod can be pressed onto the second support leg.

[0010] Preferably, the lower end of the V-shaped inclined clamping block is provided with a T-shaped step, the T-shaped step is inclined, and the V-shaped inclined clamping block is slidably connected to the T-shaped groove on the lower bottom surface of the wiring groove through the T-shaped step.

[0011] Preferably, the cable fixing assembly includes a support block, a sleeve, and a wire clamping post. The support block is fixed inside the lower fixing seat.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0015] This utility model of an anti-loosening and anti-vibration cable clamp uses a V-shaped inclined clamping block and a cable clamping component within the wiring assembly to secure the cable. The V-shaped inclined clamping block slides in the direction the cable may detach, causing it to slide along the T-slot, thus reducing the space needed to clamp the cable. An anti-slip plate is located at the lower end of the cable clamping component; its rotation causes the front end of the first leg to tightly clamp the cable, preventing it from slipping out and improving cable stability. Shock-absorbing components are located on the outer side of the clamp body and at the connection between the upper and lower fixing seats to mitigate shaking within the wiring assembly. A cable fixing component is located at the front end of the wiring slot to secure the cable end, effectively reducing clamp displacement caused by vibration. The upper end of the cable clamping component features a threaded rod and a third spring; the adjustable threaded rod allows for fastening cables of different specifications, offering strong adaptability. This cable clamp reduces the use of bolts, decreases the workload of working at heights, and lowers the labor intensity for workers. Attached Figure Description

[0024] The core of this utility model is to provide a non-loosening and anti-vibration wire clamp, which improves the anti-vibration performance and stability of the wire clamp through the wiring assembly and cable fixing assembly.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. 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.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Refer to the attached diagram. Figure 1 This is a schematic diagram of the main view of the anti-loosening and anti-vibration cable clamp of this utility model; Figure 2 This utility model is for Figure 1Schematic diagram of the cross section of AA; Figure 3 This is a left-side view of the anti-loosening and anti-vibration cable clamp of this utility model; Figure 4 This is a schematic diagram of the left sectional view of the anti-loosening and anti-vibration cable clamp of this utility model; Figure 5 This is a three-dimensional schematic diagram of the card wire assembly in this utility model; Figure 6 This is a left-side view of the V-shaped inclined clamping block in this utility model.

[0028] In one specific implementation, such as Figures 1-6 As shown, a non-loosening and shock-absorbing wire clamp includes a wire clamp body 1. An upper fixing seat 2 and a lower fixing seat 3 are respectively connected to the upper and lower outer sides of the wire clamp body 1. The upper fixing seat 2 and the lower fixing seat 3 are snapped together. The wire clamp body 1 is interconnected with the inner sidewalls of the upper fixing seat 2 and the lower fixing seat 3 via several shock-absorbing components 4. Each shock-absorbing component 4 includes two damping rods 401 and a shock-absorbing spring 402. The upper and lower ends of the damping rods 401 are fixed to the inner end faces of the upper fixing seat 2 and the lower fixing seat 3, and the outer end faces of the wire clamp body 1, respectively. The shock-absorbing spring 402 is fitted onto the damping rods 401. This design buffers the vibration between the upper fixing seat 2 and the lower fixing seat 3 and the wire clamp body 1.

[0029] In one specific implementation, such as Figures 1-6 As shown, two wiring slots 101 are arranged side by side inside the wire clamp body 1. Each wiring slot 101 contains a set of wiring components 5, and the wiring ports of the two wiring components 5 are installed opposite each other. The wiring component 5 includes a V-shaped inclined clamping block 51 on its bottom surface. There are two V-shaped inclined clamping blocks 51, which are symmetrically installed on the bottom surface of the wiring slot 101.

[0030] Specifically, such as Figure 6 The V-shaped inclined clamping block 51 has a T-shaped step at its lower end, which slopes upwards. During cable installation, the V-shaped inclined clamping block 51 slides downwards along the T-shaped step, increasing the gap between the two V-shaped inclined clamping blocks 51 and facilitating cable installation. After the cable is installed and secured by the upper fixing clamping assembly 52, if the cable becomes loose, the two V-shaped inclined clamping blocks 51 move upwards along the T-shaped step, reducing the gap between them and securing the cable.

[0031] In one specific implementation, such as Figures 1-6As shown, the upper end of the V-shaped inclined clamping block 51 is provided with a wire clamping assembly 52. ​​The wire clamping assembly 52 is installed in the wiring groove 101 through a pin 53. The wire clamping assembly 52 includes a wire clamping plate 521 and a support 522. The support 522 is installed on the outside of the wire clamping plate 521. Both the support 522 and the wire clamping plate 521 are provided with round holes through which the pin 53 can pass. The support 522 and the wire clamping plate 521 are coaxially installed on the pin 53 through the round holes. A threaded rod 54 is fixedly connected to the upper end of the support 522. The threaded rod 54 is threaded through the top wall of the wiring groove 101. A spring hole is provided in the wiring groove 101. The threaded rod 54 is fitted in the first spring 55. The threaded rod 54 is threadedly connected to the upper fixed seat 2, and a nut 56 is installed between the threaded rod 54 and the upper fixed seat 2. The nut 56 can adjust the threaded rod 54 to slide up and down and prevent the threaded rod 54 from loosening. A pressure rod 57 is installed at the rear end of the threaded rod 54. The pressure rod 57 and the threaded rod 54 are installed parallel to each other on the upper fixed seat 2 and the wire clamp body 1. A second spring 58 is provided between the pressure rod 57 and the upper fixed seat 2, so that the pressure rod 57 is disengaged from the wire clamping plate 521 when it is not in operation.

[0032] Specifically, the cable clamping plate 521 includes a first leg 5211, a second leg 5212, and an anti-slip plate 5213. The anti-slip plate 5213 is fixedly connected between the first leg 5211 and the second leg 5212. The first leg 5211, the second leg 5212, and the anti-slip plate 5213 are an integral structure. A torsion spring 523 is provided inside the cable clamping plate 521. The torsion spring 523 passes through the pin 53. One side of the torsion spring 523 is mounted on the upper end face of the first leg 5211, and the other side of the torsion spring 523 is mounted on the side of the support 522. The side of the wiring groove 101 has an oblong hole 102, and the pin 53 slides up and down in the oblong hole 102. The anti-slip plate 5213 abuts against the cable and will rotate along the tendency of the cable to fall off. Under the action of the anti-slip plate 5213, the first leg 5211 will firmly clamp the cable.

[0033] In one specific implementation, such as Figure 5 As shown, the first leg 5211 has an inverted "7" shaped structure, and the front end of the first leg 5211 has a serrated structure.

[0034] In one specific implementation, such as Figures 1-6As shown, the front end of the wiring assembly 5 is provided with a cable fixing assembly 6, and the upper and lower ends of the cable fixing assembly 6 are fixed on the upper fixing seat 2 and the lower fixing seat 3, respectively. The cable fixing assembly 6 includes a support block 601, a sleeve 602, and a wire clamping post 603. The support block 601 is fixed inside the lower fixing seat 3. The support block 601 has a V-shaped groove for placing the cable. The upper end of the support block 601 has a wire clamping post 603. The wire clamping post 603 is slidably mounted on the sleeve 602. The wire clamping post 603 passes through the sleeve 602 and through the upper fixing seat 2. The wire clamping post 603 and the upper fixing seat 2 are provided with a third spring 604. The outer wall of the wire clamping post 603 is provided with a stop pin 605 perpendicular to the axial direction. The stop pin 605 is located on the lower end face of the upper fixing seat 2. The upper outer wall of the sleeve 602 has an inverted "F" shaped groove. Pressing and rotating the wire clamping post 603 causes the stop pin 605 on the wire clamping post 603 to slide in the inverted "F" shaped groove. When pressing and rotating, the stop pin 605 falls into the horizontal retaining groove with an inverted "F" shape, making it less likely to fall off.

[0035] This utility model of anti-loosening and anti-vibration cable clamp, when installing a cable, first passes the cable end through the cable fixing assembly 6. At this time, the stop pin 605 on the pressure post 603 falls at the uppermost end of the vertical groove of the inverted "F" shaped groove of the sleeve 602. Under the pushing action of the third spring 604, the outer side of the stop pin 605 abuts against the lower end face of the upper fixing seat 2. Rotate the nut 56 to make the threaded rod 54 rise, thereby driving the cable clamping assembly 52 to move upward to a suitable position. Place the cable in the V-shaped groove of the support block 601, and press the second leg 5212 of the cable clamping assembly 52 with the pressure rod 57. The front end of the first leg 5211 is raised, so that the first leg 5211 and the second leg 5212 are kept in a horizontal position, which facilitates the cable passing through. After the cable passes through the clamp body 1, release the pressure rod 57. Under the action of the second spring 58, the pressure rod 57 springs upward, so that the bottom end of the pressure rod 57 disengages from the second leg 5212. Under the action of the torsion spring 523, the first support leg 5211 of the cable clamping plate 521 tilts forward. Rotating the nut 56 at the upper end of the upper fixed seat 2 causes the support 522 to move downwards under the drive of the threaded rod 54 until the anti-slip plate 5213 contacts the cable. The serrated edge of the first support leg 5211 also clamps the cable onto the V-shaped inclined clamping block 51. Pressing the rear clamping post 603 causes the lower end of the clamping post 603 to press the cable. Rotating the clamping post 603 causes the stop pin 605 on the clamping post 603 to engage in the inverted "F"-shaped horizontal groove, thus clamping the rear cable. If the cable loosens and retracts, the anti-slip plate 5213 rotates backwards under the action of retraction. Meanwhile, the lower V-shaped inclined clamping block 51 moves obliquely upwards, making the gap between the V-shaped inclined clamping blocks 51 smaller and smaller. The reduced gap between the anti-slip plate 5213 and the V-shaped inclined clamping block 51 prevents the cable from falling off the clamping plate 521. A shock-absorbing component 4 is installed between the clamp body 1 and the upper and lower fixing seats 3, and cable fixing components 6 are provided at both ends of the clamp body 1. When the cable vibrates, the two ends of the cable are fixed to the upper fixing seat 2 and the lower fixing seat 3 by the cable fixing components 6. Simultaneously, the clamp body 1 and the front end of the cable are fixed within the upper fixing seat 2 and the lower fixing seat 3, resulting in relative vibration-free operation and preventing vibration between the cable and the clamping component 52. This makes it less likely for the cable to fall off the clamp body 1, improving the cable's stability. It also reduces the use of bolts during cable installation, reduces the amount of work at height, and lowers the labor intensity of workers.

Similar or identical parts between embodiments can be referred to interchangeably.
