Description

Technical Field

[0001] This utility model relates to the technical field of communication cable fixing structures, specifically to a communication cable fixing clip that prevents loosening. Background Technology

[0002] In fields such as telecommunications, power, and data centers, standardized cabling and reliable securing of cables (such as communication cables, optical cables, and power cords) are crucial for ensuring stable system operation. Cable clips, as a common cable securing device, are widely used to bundle and secure cables to mounting bases such as cabinets, cable trays, and walls.

[0003] Currently, there are various types of cable clamps on the market. One common structure uses a snap-fit ​​connection, where a component with elastic claws directly snaps into the hole of another component for connection. While this structure is convenient to install, its inherent drawback is that the elastic claws are prone to creep or fatigue deformation under long-term vibration, external tension, or stress caused by temperature changes. This can cause the claws to loosen from the locking hole, rendering the entire clamp ineffective and posing a risk of cable detachment.

[0004] Furthermore, traditional cable clamps typically have a fixed installation angle. In actual installation, due to deviations in the installation hole positions or changes in cable routing, installers often find it difficult to adjust the angle of the clamp to suit the optimal cable laying direction, leading to installation inconvenience and potentially affecting the transmission performance or lifespan of the cable due to forced bending.

[0005] Therefore, there is an urgent need for a new type of cable clamp that can effectively solve the inherent problem of loosening in snap-fit ​​connections, improve the reliability of fixing, and provide flexible adjustment functions to facilitate installation and construction. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a communication cable fixing clip to prevent loosening, comprising a clip body structure and a fixing plate for fixing two cables. The clip body structure includes a bracket and a pressure block. The bracket has upwardly curved limiting plates on both sides, and the pressure block has downwardly curved side plates on both sides. The side plates cooperate with the limiting plates to fix the cables. The fixing plate has mounting holes at both ends and a through hole with a buckle in the middle. The bracket has a round hole in the middle, and the buckle is inserted into the round hole to allow the fixing plate and the bracket to rotate relative to each other. The bottom surface of the pressure block has a protruding ridge between the cables, and the middle of the pressure block has a stepped hole. A column and a spring are installed in the stepped hole. The bottom end of the column is inserted into the through hole of the fixing plate and limited by the protrusion. Its bottom end is located inside the buckle to prevent the buckle from loosening.

[0008] Furthermore, the rotatable connection between the fixing plate and the bracket is achieved through a rotating pair formed after the buckle is engaged with the round hole.

[0009] Furthermore, the protruding ridge extends along the axial direction of the cable.

[0010] Furthermore, the protrusion of the column is an annular flange surrounding its bottom end.

[0011] Furthermore, the spring is a compression spring, with its lower end abutting against the stepped surface of the stepped hole and its upper end abutting against the edge of the top of the column.

[0012] Furthermore, the curvature of the limiting plate and the side plate is adapted to the outer diameter of the cable.

[0013] Furthermore, the column and the stepped hole of the pressure block are in a sliding fit.

[0014] Furthermore, the bracket and pressure block are made of engineering plastics.

[0015] This utility model has the following beneficial effects:

[0016] (1) This utility model solves the problem of easy loosening of traditional snap-fit ​​connections by extending the bottom end of the column into the inside of the buckle.

[0017] (2) This utility model achieves stepless adjustment of the installation angle through the rotatable connection design between the fixing plate and the bracket. The installer can first fix the fixing plate firmly to the base through the mounting holes at both ends, and then rotate the bracket and the entire buckle structure 360 ​​degrees to accurately align the cable laying direction.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] 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 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.

[0030] Please see Figures 1-6 As shown, this utility model is a communication cable fixing clip to prevent loosening, including a fixing plate 1, a buckle structure, and an elastic clamping mechanism. The buckle structure is used to clamp and fix two communication cables 6 arranged side by side, and it consists of a bracket 2 and a pressure block 3.

[0031] The fixing plate 1 is typically a long strip with a pair of mounting holes at both ends, preferably bolt holes or screw holes, for mounting the entire fixing clamp to the target base (such as a wall, cabinet, etc.) using fasteners such as bolts. A through hole is located in the center of the fixing plate 1, and multiple (usually three or more) elastic clips 101 are evenly distributed around the perimeter of this through hole. These clips 101 are preferably integrally stamped with the fixing plate 1.

[0032] The bracket 2 serves as a base for supporting the cable 6, and has a circular hole in its center. During installation, the fixing plate 1 is placed above the bracket 2, and force is applied to deform the buckle 101 in the center of the fixing plate 1, causing it to snap into the circular hole of the bracket 2. After the buckle 101 returns to its original shape, its hook can engage with the edge of the circular hole, thereby connecting the fixing plate 1 and the bracket 2 together. Due to the play between the buckle 101 and the circular hole, the fixing plate 1 and the bracket 2 can rotate relative to each other, forming a rotating pair, which facilitates angle adjustment during installation to accommodate different cable routes. The opposite sides of the bracket 2 are bent upward to form limiting plates 201, which are used to limit and support the cable 6 from below and from the outside.

[0033] The pressure block 3 is vertically aligned with the bracket 2, and its opposite sides are bent downwards to form side plates 301. A protruding ridge protrudes downwards from the bottom surface of the pressure block 3 (i.e., the side facing the cable), preferably extending along the axial direction of the cable 6, to fit into the gap between the two cables 6 during clamping, preventing the cable 6 from shifting left and right. A stepped hole 302 is formed in the middle of the pressure block 3.

[0034] The elastic clamping mechanism includes a column 4 and a spring 5. The column 4 is slidably inserted into the stepped hole 302 of the pressure block 3. The bottom end of the column 4 extends downward and inserts into the through hole of the fixing plate 1. The bottom end of the column 4 is provided with a protrusion 401, preferably an annular flange surrounding the column. The size of the protrusion 401 is larger than the diameter of the through hole of the fixing plate 1, thereby forming a limit to prevent the column 4 from completely coming out of the through hole. The spring 5 is sleeved on the column 4 and placed in the stepped hole 302. In this embodiment, the spring 5 is a compression spring, with its lower end abutting against the stepped surface of the stepped hole 302 and its upper end abutting against the edge provided at the top of the column 4.

[0035] In its natural state, the spring 5 is pre-compressed, and its elastic force pushes the column 4 upward relative to the pressure block 3 until the protrusion 401 at the bottom of the column 4 is stopped by the upper limit of the through hole edge of the fixing plate 1; at the same time, the reaction force of the spring 5 acts downward on the step surface of the step hole 302, thereby continuously pushing the pressure block 3 to have a downward tendency to move closer to the bracket 2, providing pre-tightening force for clamping the cable 6.

[0036] After assembly, the bottom end of the column 4 and the protrusion 401 are located inside all the clips 101 on the fixing plate 1. This design effectively prevents the clips 101 from undergoing excessive elastic deformation or even coming out of the round hole of the bracket 2 due to inward force, greatly enhancing the reliability and anti-loosening ability of the connection between the fixing plate 1 and the bracket 2.

[0037] In use, manually lift the pressure block 3 upwards to overcome the downward force of the spring 5, causing the pressure block 3 to move upwards and open the clamping space. Place the two cables 6 side by side between the limiting plates 201 of the bracket 2. Then release the pressure block 3. Under the restoring force of the spring 5, the pressure block 3 automatically moves downwards until its side plates 301 and the limiting plates 201 of the bracket 2 together clamp the cables 6. The protruding ridges on the bottom of the pressure block 3 press between the two cables. This design enables rapid clamping and release of the cables.

[0038] Preferably, the bending arc design of the limiting plate 201 and the side plate 301 is adapted to the outer diameter of the fixed cable 6 to increase the contact area, avoid damage to the cable sheath, and provide sufficient clamping force. The bracket 2 and the pressure block 3 can be made of engineering plastics (such as PA, PC, etc.), which are lightweight, insulating, and have a certain strength and elasticity. The column 4 and the stepped hole 302 are in a sliding fit to ensure that the pressure block 3 can be smoothly pressed down and lifted.

[0039] like Figure 7 As shown, the lengths of the limiting plate 201 and the side plate 301 are adjusted according to actual usage requirements.
