Description

Technical Field

[0001] This utility model relates to the field of cable fixing head technology, and in particular to a fixing head. Background Technology

[0002] A cable clamp is a device used to secure cables to equipment, appliances, or buildings. It is also known as a cable connector, cable clamp, or cable fixing device. When in use, the cable passes through the cable clamp, and then the clamp can be inserted into a pre-drilled hole in the equipment chassis. After the clamp is inserted into the column of the chassis, a nut can be screwed on. Under the clamping action of the nut and the head of the clamp, the clamp can be fixed at the equipment chassis, thus securing the cable to the cable inlet hole of the equipment chassis.

[0003] When using existing cable clamps to secure cables at the equipment chassis, the nuts at the back of the clamps are prone to loosening due to vibrations in the equipment chassis. Once the nuts loosen, the internal cables lose pressure and become loose, affecting the stability of the cables at the equipment chassis. To address this, we propose a new type of clamp. Utility Model Content

[0004] The main objective of this invention is to provide a cable fixing head with a cable locking mechanism. The locking mechanism's toothed rubber ring and tapered rubber locking sleeve effectively grip the cable within the fixing head body, preventing loosening. The groove design causes the fixing head body to slightly retract under pressure, further enhancing cable fixation in conjunction with the tapered rubber locking sleeve's contraction. Furthermore, flange nuts A and B, supported by springs, provide elastic support, preventing flange nut A from loosening due to vibration. This ensures the stability of the entire fixing head connection at the equipment chassis, firmly securing the cable within the chassis and preventing loosening, effectively solving the problems described in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A fixing head includes a fixing head body and a stop block. The stop block is integrally formed on the cylindrical body of the fixing head body. The fixing head body also includes a cable locking mechanism, which includes a toothed rubber ring, a flange nut A, a flange nut B, a spring, and a tapered rubber locking sleeve. The toothed rubber ring is fitted inside the fixing head body above the stop block, and the flange nut A and flange nut B are screwed onto the fixing head body below the stop block. A spring fitted on the outside of the fixing head body is clamped between the flange nut A and flange nut B. The fixing head body has cross-shaped grooves distributed below the flange nut B, and a tapered rubber locking sleeve is inserted into the fixing head body between the grooves.

[0007] Furthermore, the tapered rubber lock sleeve has a side-opening groove on one side of the sleeve body, and a C-shaped rib protrudes from the inside of the tapered rubber lock sleeve. The outer wall of the tapered rubber lock sleeve is provided with a rough sleeve surface.

[0008] By adopting the above technical solution, when the flange nut B is screwed onto the fixed head body with the shrinkage groove, causing the fixed head body to shrink, the tapered locking sleeve with the side-opening sleeve groove can shrink after being subjected to force, thereby cooperating with the C-shaped convex rib to bite the cable.

[0009] Furthermore, the head cavity of the fixing head body is recessed and a toothed rubber ring is inserted into the cavity, and the inner ring wall of the toothed rubber ring has protruding teeth.

[0010] By adopting the above technical solution, a toothed rubber ring can be installed in the concave cavity at the head cavity of the fixing head body, which facilitates the toothed rubber ring to bite the cable that penetrates into the fixing head body.

[0011] Furthermore, the groove of the shrinkage groove is provided in four sets in a cross-shaped distribution outside the threaded cylinder of the fixed head body;

[0012] By adopting the above technical solution, after opening a groove at the fixed head body, the threaded column itself can slightly shrink inward when compressed.

[0013] Furthermore, the opposing disc surfaces of flange nuts A and B are recessed with annular grooves, and the two end spring rings of springs are fitted into the annular grooves of flange nuts A and B.

[0014] By adopting the above technical solution, flange nut A and flange nut B can be clamped in the spring cavity by means of the ring groove, so that flange nut A and flange nut B form an elastic support with the spring, preventing flange nut A from being loosened by vibration.

[0015] Furthermore, the block thickness of flange nut B is greater than the block thickness of flange nut A, and the threaded cavity depth of flange nut B is greater than the threaded cavity depth of flange nut A.

[0016] By adopting the above technical solution, flange nut B can obtain a larger support surface at the fixed head body, thereby cooperating with the spring to support flange nut A.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model provides a cable locking mechanism at the fixing head body for cables. The toothed rubber ring, tapered rubber locking sleeve and other components of the cable locking mechanism can effectively grip the cable in the fixing head body to prevent the cable from loosening. The groove design causes the fixing head body to shrink slightly inward when pressed, which, together with the shrinkage of the tapered rubber locking sleeve, further enhances the fixation of the cable.

[0019] Furthermore, flange nut A and flange nut B form an elastic support with the help of springs, preventing flange nut A from being reversed and loosened due to vibration, ensuring the connection stability of the entire fixing head at the equipment chassis, and making the cable firmly fixed inside the equipment chassis, not easy to loosen.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1-3 As shown, a fixing head includes a fixing head body 1 and a stop block 2. The stop block 2 is integrally formed on the cylindrical body of the fixing head body 1. The fixing head body 1 also includes a cable locking mechanism 3. The cable locking mechanism 3 includes a toothed rubber ring 5, a flange nut A6, a flange nut B7, a spring 8, and a tapered rubber locking sleeve 11. The toothed rubber ring 5 is inserted into the fixing head body 1 above the stop block 2, and the flange nut A6 and flange nut B7 are screwed onto the fixing head body 1 below the stop block 2. The spring 8 is clamped between the flange nut A6 and flange nut B7 and is sleeved on the outside of the fixing head body 1. The fixing head body 1 inside the flange nut B7 has cross-shaped grooves 10 distributed below it. The tapered rubber locking sleeve 11 is inserted into the fixing head body 1 between the grooves 10.

[0026] The tapered rubber lock sleeve 11 has a side opening groove on one side of the sleeve body, and a C-shaped rib protrudes from the inside of the tapered rubber lock sleeve 11. The outer wall of the tapered rubber lock sleeve 11 is provided with a rough sleeve surface.

[0027] By adopting the above technical solution, when the flange nut B7 is screwed onto the fixed head body 1 with the shrinkage groove 10, causing the fixed head body 1 to shrink, the tapered locking sleeve 11 with the side opening groove can shrink after being subjected to force, thereby cooperating with the C-shaped rib to bite the cable.

[0028] The fixed head body 1 has a recessed cavity 4 in the head cavity, and a toothed rubber ring 5 is inserted into the cavity of the recessed cavity 4. The toothed rubber ring 5 has protruding teeth on the inner ring wall.

[0029] By adopting the above technical solution, the toothed rubber ring 5 can be installed in the inner cavity 4 at the head cavity of the fixing head body 1, thereby facilitating the toothed rubber ring 5 to bite the cable that penetrates into the fixing head body 1.

[0030] Among them, the groove 10 has four sets of grooves distributed in a cross shape outside the threaded cylinder of the fixed head body 1.

[0031] By adopting the above technical solution, after the groove 10 is opened at the fixed head body 1, the threaded column itself can be slightly retracted after being compressed.

[0032] Among them, the opposing disc surfaces of flange nuts A6 and B7 are recessed with annular grooves 9, and the two end spring rings of spring 8 are clamped in the annular grooves 9 of flange nuts A6 and B7.

[0033] By adopting the above technical solution, flange nut A6 and flange nut B7 can be clamped in the spring cavity of spring 8 by means of the ring groove 9, so that flange nut A6 and flange nut B7 form an elastic support with spring 8, preventing flange nut A6 from being loosened by vibration.

[0034] Wherein, the block thickness of flange nut B7 is greater than the block thickness of flange nut A6, and the threaded cavity depth of flange nut B7 is greater than the threaded cavity depth of flange nut A6.

[0035] By adopting the above technical solution, the flange nut B7 can obtain a larger support surface at the fixed head body 1, thereby cooperating with the spring 8 to support the flange nut A6.

[0036] It should be noted that this utility model is a fixing head. By setting a cable locking mechanism 3 at the fixing head body 1 for cables, when the fixing head body 1 needs to be inserted and fixed at the cable pre-drilled hole in the equipment chassis, the fixing head body 1 behind the stop block 2 can be inserted into the chassis along the pre-drilled hole. Then, the tapered rubber locking sleeve 11 can be inserted from the rear cavity of the groove 10 set in the fixing head body 1, and the toothed rubber ring 5 can be locked in the inner cavity of the fixing head body 1. Then, the flange nut A6 can be screwed onto the fixing head body 1 inside the chassis. The cable can pass through the toothed rubber ring 5, the fixing head body 1, and the tapered rubber locking sleeve 11 and enter the chassis. Then, the spring 8 is sleeved on the flange nut A6. At the fixed head body 1, continue to screw on the flange nut B7, so that the flange nut B7 presses against the spring 8 to support the flange nut A6 for elastic anti-reverse. When the flange nut B7 is screwed on the fixed head body 1 with the shrink groove 10, the fixed head body 1 shrinks. The tapered locking sleeve 11 with the side opening groove can shrink after being subjected to force, thereby cooperating with the C-shaped rib to bite the cable, so that the cable is firmly fixed in the equipment box by the fixed head body 1 and is not easy to loosen. After loosening the flange nut B7, the spring 8 can be removed, and then the flange nut A6 can be screwed away. At this time, the fixed head body 1 can be removed from the equipment box, and the cable inside the fixed head body 1 can be pulled out for maintenance.

[0037] It should be noted that this utility model is a fixing head, and all components in this utility model are known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
