Description

Technical Field

[0001] The utility model relates to the technical field of cable fixing devices, and specifically relates to a cable bundle quick fixing and disassembly device suitable for confined spaces. Background Art

[0002] In conventional cabinet assembly, the various components of the cabinet are electrically connected through cables. The plug-in boxes inside the cabinet are required to have two states: fully pulled out and pushed into place. Therefore, the cable bundles connecting the plug-in boxes and the cabinet must have two states: straightened and retracted. The cable bundles are subject to stress during the alternating activities between the two states. To ensure reliability, the cable bundles are generally fixed with metal cable fixing cards, and they must be firmly fixed. Since the space for cable bundles at the rear of most cabinets is limited, the high-point fixing principle must be followed in the alternating activity area between the two states to ensure the maximum bending radius of the cable bundles when they are retracted, fully utilize the space to retain the cable bundles, and minimize the risk of the cable bundles being squeezed in the bottom tray. The existing cable bundle fixation verification is as follows:

[0003] Conventional cabinet cable harness fixing cards, such as Figure 7 As shown, the cable bundle is fixed by screws to the angle pieces. During the production process of this type of cabinet, there is a problem that the cabinet is difficult to install and disassemble at the front end. When installing and disassembling at the front end, it is necessary to rely on manual feel to find fasteners and blindly disassemble (install), which is difficult to operate. There is also a risk of fasteners falling. Conventional cable bundle fixing cards cannot completely fix the high points, so they are not used in the assembly of this type of cabinet.

[0004] The current method used is to fix the cable bundle at the tail of the connector. Although this solves the problem of cable bundle removal when the plug-in box is replaced, it also reduces the starting end height of the cable bundle at the plug-in box end to about 1 / 2 of the total height. After the cable bundle retracts, it is concentrated at the bottom of the tray and squeezes each other, posing quality problems and safety risks. In addition, when the plug-in box is pushed and pulled multiple times, the cable bundle will become stretched and untied, which affects the reliability of the product to a certain extent.

[0030] The following describes the specific embodiments of the present invention in detail in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the present invention. Although the present invention is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, not limiting, of the scope of the present invention.

[0031] Specific embodiment 1: Please refer to Figure 1-6A device for quickly fixing and removing cable bundles in confined spaces, comprising: a base plate 1, a curved wire clip 2, a self-locking component 3, and a loading and unloading tool 4 used in conjunction with the device. The curved wire clip 2 is arranged on the upper end of the base plate 1 through the self-locking component 3, and the curved wire clip 2 can cooperate with the self-locking component 3 to quickly fix and remove the cable bundle. This device can maximize the bending radius of the cable bundle's active trajectory, improve the cable bundle's fixing efficiency and consistency, and the built-in and mutual constraints of the structural parts have an anti-loosening effect, thereby improving product reliability.

[0032] Specifically, a first mounting groove 11 with a T-shaped structure is provided at the upper end of the base plate 1, and a limit block 12 is provided at the upper end of the first mounting groove 11, which can narrow the upper end of the first mounting groove 11; two fixing holes 13 for installing the device are also provided on the base plate 1 and the lower side of the first mounting groove 11, and the fixing holes 13 can be set as countersunk holes.

[0033] The self-locking assembly 3 includes a lock plate 31, a stopper 32, a spring 33 and a cylindrical pin 34. A second mounting groove with a T-shaped structure that is wide at the top and narrow at the bottom is opened on the upper part of the lock plate 31. The second mounting groove consists of a stopper groove 311 and a spring groove 312. The stopper 32 is slidably disposed in the stopper groove 311. The spring 33 is disposed in the spring groove 312 and its upper part at least partially extends into the stopper groove 311 and is pressed against the stopper 32. The stopper 32 consists of a connecting block 321 and a locking block 322. The size of the connecting block 321 is larger than the size of the locking block 322 and the spring groove 312. This structure is used to control the maximum stroke of the stopper 32 sliding into the second mounting groove.

[0034] The locking plate 31 is fixed to the base plate 1 by screws, and the first mounting groove 11 and the second mounting groove form a T-shaped cavity. At this time, the limit block 12 is located at the upper end of the cavity. The locking block 322 is a wedge-shaped structure and its size matches the narrowed port. Under the action of the spring 33, the stopper 32 can slide back and forth between the spring groove 312 and the limit block 12; the cylindrical pin 34 is provided as a rotating shaft through the lower end of the locking plate 31.

[0035] The arc-shaped cable clamp 2 is a C-shaped structure consisting of a first connecting portion, a cable clamping portion, and a second connecting portion. The outer end of the first connecting portion is provided with a disassembly port 21 and two installation ports 22. The two installation ports 22 are symmetrically arranged on the front and rear sides of the disassembly port 21. The size of the disassembly port 21 is adapted to the size of the locking block 322. The inner side of the cable clamping portion is an arc-shaped structure. In one embodiment, the inner diameter of the inner side of the cable clamping portion can be determined according to the size of the cable bundle to be fixed.

[0036] Of course, in order to fix and compress the cable bundle, the inner side of the cable clamping part can also be set to a serrated shape, so that the fixed and compressed cable bundle is more stable and not easy to loosen by increasing the friction and local pressure; the outer end of the second connecting part is set to two shaft sleeves 23, and the two shaft sleeves 23 are both sleeved on the cylindrical pin 34, so that the arc line card 2 can be rotatably connected to the locking plate 31 through the cylindrical pin 34. Under the action of external force, the arc line card 2 can be flipped relative to the locking plate 31. When the arc line card 2 is flipped to the position where the first connecting part coincides with the stop 32, the stop 32 is first pressed into the cavity, and then when the disassembly port 21 reaches the stop 32, the stop 32 pops into the disassembly port 21 to form a lock.

[0037] The main body of the loading and unloading tool 4 is a plate-shaped structure, and a disassembly end 41 is provided at one end of the loading and unloading tool 4. The size of the disassembly end 41 is adapted to the size of the disassembly port 21. When the disassembly end 41 is pressed into the disassembly port 21, the stopper 32 can be pressed into the cavity to release the lock; the other end of the loading and unloading tool 4 is provided with two locking ends 42 of a columnar structure, and the size and arrangement of the locking ends 42 correspond to the two installation ports 22. When the locking end 42 is inserted into the installation port 22, the arc-shaped line card 2 can be conveniently flipped over by lever to complete the fixation of the cable bundle.

[0038] This device enables rapid top-mounted cable harness installation and removal, maximizes the bending radius of the cable harness's trajectory, and improves both efficiency and consistency in cable harness installation. The internal and interlocking structural components prevent loosening, enhancing product reliability. Furthermore, the original subrack design remains unchanged, minimizing upgrade costs.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
