Description

Technical Field

[0001] This utility model relates to the field of wire and cable technology, specifically to a high conductivity wire and cable that is resistant to tension and bending. Background Technology

[0002] High-conductivity wires and cables with tensile and bending resistance typically combine multiple properties such as tensile and bending resistance as well as high conductivity, making them suitable for various applications requiring mechanical stress and electrical transmission, such as industrial electronics, warehousing and metallurgy, port machinery, and marine engineering.

[0003] According to Chinese Patent Publication No. CN213366187U, "A Tensile-Resistant Wire and Cable," the main improvement is achieved by adding a first tensile rope, which is twisted with the insulated core wire to form the wire core. The first tensile rope is made of multiple sets of twisted steel wires, giving the wire core strong tensile strength and bending ability. Simultaneously, by setting a wear-resistant protective sleeve and wear-resistant protrusions, the cable's wear resistance is improved, preventing the sheath from breaking and exposing the wire core after a period of use. Furthermore, setting multiple sets of second tensile ropes inside the wear-resistant protective sleeve enhances its tensile performance, further improving the cable's tensile strength.

[0004] High-conductivity, tensile and bending resistant wires and cables need to be moved and bent during actual use. The outer sheath of the cable and the inner conductor will wear due to friction, especially at the contact points between the cable and equipment or other objects. Over long-term use, this can lead to embrittlement and increase the risk of breakage.

[0005] Therefore, a high-conductivity wire and cable with tensile and bending resistance is proposed to solve the problem that the cable end will become brittle and increase the risk of breakage under long-term use at the contact point with equipment or other objects. Utility Model Content

[0006] The technical problem this utility model aims to solve is that the contact point between the cable end and the equipment or other object will become brittle under long-term use, increasing the risk of breakage. Therefore, a high-conductivity wire and cable with tensile and bending resistance is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a high conductivity wire and cable with tensile and bending resistance, including an outer sheath, a reinforcing layer, an inner core layer and an insulation layer. A conductor is provided in the insulation layer. The inner core layer has uniformly formed annular recesses. Both sides of the annular recesses that are far apart from each other are in contact with baffles. The outer sheath has an annular groove on the side near the port. A limiting sleeve is fitted in the annular groove. A heat shrink sleeve is fitted on the limiting sleeve. A connecting plate is fixedly connected to one side of the heat shrink sleeve.

[0008] As a preferred technical solution of this utility model, the outer sheath is rotatably connected to one side of an extension end. The extension end is provided in four shapes and is tile-shaped. By providing an extendable extension end, it is easy to connect the inner core layer to the limiting sleeve.

[0009] As a preferred technical solution of this utility model, a plug is inserted into one side of the extension end, and the plug is fixedly connected to one side of the limiting plate. By setting the plug to connect the extension end, the tightness of the connection can be increased.

[0010] As a preferred technical solution of this utility model, protrusions are uniformly fixedly connected to the opposite sides of the two baffles. The protrusions contact the annular recesses. By setting the protrusions, the connection effect between the two opposing baffles can be better, and the bending resistance can be increased.

[0011] As a preferred technical solution of this utility model, a spring is in contact with the baffle, and the spring is sleeved on the insulating layer. By setting the spring, the stability of the baffle can be improved.

[0012] This utility model has the following advantages: by setting multiple annular recesses on the inner core layer of the wire and cable near the port, the stress on the cable when bending is reduced, the pressure generated during bending can be dispersed and relieved, and the baffle and protrusion provide support in the annular recesses, which can reduce the embrittlement problem of the cable end when bending and improve wear resistance.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-3The cable shown is a high-conductivity wire and cable with tensile and bending resistance, including an outer sheath 1, a reinforcing layer 2, an inner core layer 3, and an insulation layer 4. The outer sheath 1 is made of waterproof, flame-retardant, fire-resistant, and corrosion-resistant materials. The reinforcing layer 2 is made of braided metal wire. The insulation layer 4 contains conductors. The inner core layer 3 has evenly distributed annular recesses 5, with the inner side of the annular recesses 5 corresponding to the insulation layer 4. This creates multiple cavity structures on one side of the cable end, thereby improving the bending flexibility of the cable end when bent. The two sides of the annular recesses 5 that are far apart from each other are in contact with baffles 6, which are made of rubber. The outer sheath 1 has an annular groove 7 on the side near the port. A limiting sleeve 8 is fitted inside the annular groove 7. The limiting sleeve 8 can be made of steel wire. A heat-shrinkable sleeve 9 is fitted on the limiting sleeve 8, and a connecting plate is fixedly connected to one side of the heat-shrinkable sleeve 9.

[0019] The outer sheath 1 is rotatably connected to one side of an extension end 11. There are four extension ends 11, and the extension ends 11 are tile-shaped. By setting four expandable extension ends 11, the connection between the limiting sleeve 8 and the annular groove 7 can be facilitated, thereby improving the operating efficiency.

[0020] One side of the extension end 11 is connected to a rod 10, which is fixedly connected to one side of the limiting plate. By setting the rod 10 and the connecting plate, the extension plate 11 can be easily limited by the insertion method.

[0021] Among them, two baffles 6 are uniformly fixedly connected to one side of opposite sides with protrusions 13. The protrusions 13 contact the annular recess 5. By setting the protrusions 13 on the baffles 6, the annular recess 5 can be supported.

[0022] Among them, the baffle 6 is in contact with a spring 12, which is sleeved on the insulating layer 4. The spring 12 is set to increase the support effect of the baffle 6.

[0023] Working principle: When it is necessary to bend the end of the wire and cable, first cut four extension ends 11 at the end of the wire and cable, then appropriately shave off part of the inner core layer 3. The annular recess 5 and the baffle 6 inside the annular recess 5 are squeezed and will produce adaptive shrinkage. Then, the end of the limiting sleeve 8 forms a spiral structure to limit the position of the inner core layer 3 near the port. Then, the heat shrink sleeve 9 and the connecting plate are fitted onto the outer sheath 1 near the end of the wire and cable. Then, hot air is blown to shrink the heat shrink sleeve 9, thereby providing the bending effect of the wire and cable.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
