Description

Technical Field

[0001] This utility model relates to the field of power accessories, and in particular to a drag-resistant sheathed cable. Background Technology

[0002] Currently, most towing cables are arranged within cable chains, and several towing cables are typically arranged within a cable chain. Because the current practice is to simply place the towing cables within the cable chain without any restraining structures between adjacent cables, the cables within the chain are prone to tangling and becoming tangled during repeated operation. This causes significant inconvenience for maintenance personnel in inspecting and replacing individual towing cables. Therefore, it is essential to redesign the structure of the towing cables. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned problems and shortcomings, and to provide a drag-resistant sheathed cable. This drag-resistant sheathed cable can restrict the movement between adjacent cables to avoid entanglement and mess. When inspecting a cable in a cable chain, it can facilitate maintenance personnel to quickly and conveniently inspect and replace a cable, which can greatly improve the convenience of drag cable maintenance.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A drag-resistant sheathed cable includes a conductor and a sheath fitted on the conductor. The sheath is characterized by having at least one locking strip on its outer wall, with the length direction of the locking strip being the same as the length direction of the sheath. The sheath also has at least one protruding strip on its outer wall that can be engaged with the locking strip, with the length direction of the protruding strip being the same as the length direction of the sheath.

[0006] Preferably, the radial cross-section of the card strip is C-shaped, and the outer arc surface of the card strip is in contact with the outer wall of the sheath.

[0007] Preferably, a C-shaped steel strip with a radial cross-section is embedded in the clamping strip portion, and the length direction of the steel strip is in the same direction as the length direction of the clamping strip portion, and the steel strip is arranged around the inner cavity of the clamping strip portion.

[0008] Preferably, the sheath is embedded with a reinforcing steel strip with an arc-shaped radial cross section, and the length direction of the reinforcing steel strip is in the same direction as the length direction of the sheath. The reinforcing steel strip is arranged around the wire core and is connected to the ferrule steel strip.

[0009] Preferably, the ferrule steel strip and the reinforcing steel strip are integrally formed.

[0010] Preferably, the card strip and the sheath are integrally formed.

[0011] Preferably, the radial cross-section of the protruding part is circular.

[0012] Preferably, the outer wall of the protruding part is connected to the outer wall of the sheath by a circular arc transition.

[0013] Preferably, the raised strip and the sheath are integrally formed.

[0014] The beneficial effects of this utility model are as follows: On the drag-resistant sheathed cable, at least one locking strip and at least one protruding strip are respectively provided on the outer wall of the sheath, and the protruding strip can be secured by the locking strip. Thus, when arranging the drag-resistant sheathed cable in the cable chain, the protruding strip and locking strip on adjacent drag-resistant sheathed cables can be assembled together. This allows users to easily confine adjacent drag-resistant sheathed cables together using the protruding strip and locking strip. Furthermore, since the length directions of the locking strip and the protruding strip are the same as the length direction of the sheath, the assembly of the protruding strip and locking strip on adjacent drag-resistant sheathed cables ensures extremely accurate, stable, and comprehensive confinement of adjacent drag-resistant sheathed cables. This provides a reliable restraining effect between adjacent cables, preventing entanglement and messiness. It also facilitates quick and convenient inspection and replacement of a specific cable when maintaining a cable in the cable chain, greatly improving the convenience of drag cable maintenance. Furthermore, the retaining strip and raised strip, which run in the same direction as the length of the sheath, can effectively strengthen the sheath, thereby improving its drag resistance and extending its service life.

[0018] like Figure 1 As shown, the present invention discloses a drag-resistant sheathed cable, comprising a core body 1 and a sheath 2 fitted onto the core body 1. To achieve the purpose of the invention, at least one locking strip 21 is provided on the outer wall of the sheath 2, and the length direction of the locking strip 21 is in the same direction as the length direction of the sheath 2. At least one protruding strip 22 is provided on the outer wall of the sheath 2 for the locking strip 21 to be engaged, and the length direction of the protruding strip 22 is in the same direction as the length direction of the sheath 2.

[0019] On the drag-resistant sheathed cable, at least one locking strip 21 and at least one protruding strip 22 are respectively provided on the outer wall of the sheath 2, and the protruding strip 22 can be locked by the locking strip 21. In this way, when the drag-resistant sheathed cable is arranged in the cable chain, the protruding strip 22 and the locking strip 21 on the adjacent drag-resistant sheathed cables can be assembled together. This makes it convenient for the user to limit the adjacent drag-resistant sheathed cables together by the protruding strip 22 and the locking strip 21.

[0020] Furthermore, since the length directions of the locking strip 21 and the protruding strip 22 are in the same direction as the length direction of the sheath 2, when the protruding strip 22 and the locking strip 21 on the adjacent drag-resistant sheathed cables are assembled together, the adjacent drag-resistant sheathed cables can be bound together very accurately, stably and comprehensively. This can help to create a reliable restraining effect between adjacent cables, so as to avoid the adjacent cables from becoming tangled or messy. When inspecting a cable in the drag chain, it can help maintenance personnel to quickly and conveniently inspect and replace a cable, which can greatly improve the convenience of drag cable maintenance.

[0021] Furthermore, the retaining strip 21 and the protruding strip 22, which are in the same direction as the length of the sheath 2, can also play a good reinforcing role for the sheath 2, thereby improving the drag resistance of the sheath 2 and thus extending its service life.

[0022] like Figure 1 As shown, the radial cross-section of the retaining strip 21 is C-shaped, and the outer arc surface of the retaining strip 21 is in contact with the outer wall of the sheath 2. This gives the retaining strip 21 a very simple and reliable structure, which not only reduces the manufacturing difficulty, but also enables the retaining strip 21 to perform a reliable clamping effect, thereby helping to further improve the reliability and applicability of the drag-resistant sheathed cable.

[0023] like Figure 1 As shown, a C-shaped clamping steel strip 23 is embedded in the clamping section 21, with its length direction aligned with that of the clamping section 21. The clamping steel strip 23 is also arranged around the inner cavity 24 of the clamping section 21. The clamping steel strip 23 provides reliable reinforcement to the clamping section 21, enabling it to perform a more stable and reliable clamping function, thereby further improving the reliability and applicability of the drag-resistant sheathed cable.

[0024] like Figure 1As shown, a reinforcing steel strip 25 with an arc-shaped radial cross-section is embedded in the sheath 2, and the length direction of the reinforcing steel strip 25 is in the same direction as the length direction of the sheath 2. The reinforcing steel strip 25 is arranged around the wire core 1 and is connected to the clamping steel strip 23. This not only strengthens the structural strength of the sheath 2 with the reinforcing steel strip 25, but also provides reliable restraint to the clamping steel strip 23, making the installation and positioning of the clamping steel strip 23 more stable and reliable.

[0025] like Figure 1 As shown, the ferrule steel strip 23 and the reinforcing steel strip 25 are integrally formed. This not only facilitates mass production but also allows the ferrule steel strip 23 to perform a more stable and reliable ferrule function, and the reinforcing steel strip 25 to perform a more stable and reliable reinforcing function, thereby helping to further improve the reliability and applicability of the drag-resistant sheathed cable.

[0026] Both the ferrule steel strip 23 and the reinforcing steel strip 25 are elastic steel strips, which can meet the normal bending requirements of the drag-resistant sheathed cable, thus meeting the needs of actual use.

[0027] like Figure 1 As shown, the locking strip 21 and the sheath 2 are integrally formed. This not only facilitates mass production but also enables the locking strip 21 to perform a more stable and reliable locking function.

[0028] like Figure 1 As shown, the radial cross-section of the protruding strip 22 is circular. This not only gives the protruding strip 22 a reliable structure, but also facilitates the fastening and stable clamping effect of the clamping strip 21.

[0029] like Figure 1 As shown, the outer wall of the protruding part 22 is connected to the outer wall of the sheath 2 by a rounded transition. This enhances the stability and reliability of the installation and positioning of the protruding part 22, and effectively prevents the protruding part 22 from detaching.

[0030] like Figure 1 As shown, the raised strip 22 and the sheath 2 are integrally formed. This not only facilitates mass production but also allows the raised strip 22 to perform a more stable and reliable positioning function.

[0031] like Figure 2 and Figure 3 As shown, when assembling the drag-resistant sheathed cable, adjacent drag-resistant sheathed cables are assembled together through the corresponding clamping strip 21 and protruding strip 22. This confines adjacent drag-resistant sheathed cables together to prevent them from becoming tangled or messy. When inspecting a cable in the drag chain, it allows maintenance personnel to quickly and conveniently inspect and replace that cable, greatly improving the convenience of drag cable maintenance.
