Description

Technical Field

[0001] The utility model relates to the technical field of cable wires, in particular to a tensile and bend-resistant cable. Background Technique

[0002] In terms of structural design and material selection, traditional cables often cannot well meet the requirements of tensile strength and bend resistance. Generally, a cable usually consists of a conductor, an insulating layer, and a sheath layer, and its structure is relatively simple. When subjected to tensile force, the conductor is prone to breakage or deformation, resulting in an increase in resistance, affecting the power transmission efficiency, and even causing faults such as short circuits; therefore, some tensile and bend-resistant cables have emerged on the market.

[0003] For example, a tensile and bend-resistant cable disclosed in a Chinese patent with the patent number CN202123255708.6 includes a wire and an outer cable layer. The number of the wires is four, and they are all located inside the outer cable layer. The outside of the wire is wrapped with an insulating layer, and a heat-insulating layer is arranged outside the wire, and an insulating filling layer is filled inside the heat-insulating layer; through the arrangement of a support ring and an elastic metal strip, this tensile and bend-resistant cable enables the cable to have good bend resistance and recovery. After bending, it can automatically return to its original state, and at the same time, it increases the strength and impact resistance inside the cable, protecting the inner core. Through the arrangement of a wear-resistant layer and a reinforcing rib, the cable has good wear resistance and good tensile strength, increases toughness, and extends the service life of the cable, solving the problem that the existing cable has low tensile strength and bend resistance, resulting in easy damage to the inner core.

[0004] The above-mentioned tensile and bend-resistant cable provided by the patent mainly improves the tensile and bend resistance of the cable through a support ring and an elastic metal strip. However, due to the relatively high strength of the support ring and the elastic metal strip, although the bend resistance and tensile strength of the cable are improved, it is very difficult to correct the cable if it undergoes a large bend, and it is also relatively laborious when the cable needs to be bent during laying, which is not conducive to the flexible use of the cable. Content of the Utility Model

[0005] The purpose of the utility model is to provide a tensile and bend-resistant cable, aiming to improve the problem that it is very difficult to correct the existing tensile and bend-resistant cable if it undergoes a large bend, and it is also relatively laborious when the cable needs to be bent during laying, which is not conducive to the flexible use of the cable.

[0006] The utility model is implemented as follows:

[0007] A tensile and bending-resistant cable includes a core and a strengthening core. There are multiple cores, and the multiple cores are evenly arranged around the strengthening core. A sheath is sleeved outside the strengthening core and the cores. Filler ropes are arranged between the strengthening core and the cores and between the cores and the sheath. A copper wire mesh sleeve is arranged outside the sheath, and an elastic insulating layer is arranged between the sheath and the copper wire mesh sleeve. A first rubber layer and a second rubber layer are arranged on one side outside the copper wire mesh sleeve, and a tensile buffer layer is arranged between the first rubber layer and the second rubber layer. An outer protective layer is arranged outside the second rubber layer.

[0008] Preferably, the strengthening core is processed from high-strength fiber materials, and the strengthening core is formed by helically winding multiple strands of high-strength fiber materials.

[0009] Preferably, the core is formed by stranding multiple strands of soft and fine copper wires, and a shielding layer is arranged outside the core, and an insulating rubber sleeve is arranged outside the shielding layer.

[0010] Preferably, the tensile buffer layer is woven from polyester fibers, and the tensile buffer layer is arranged outside the first rubber layer in a woven sleeve structure.

[0012] Preferably, an armor layer is further included, and the armor layer is arranged between the outer protective layer and the second rubber layer, and the armor layer is arranged in a spiral shape.

[0022] Embodiment 1

[0023] As Figure 1 and Figure 2 shown, a tensile and bend-resistant cable includes a battery cell 1 and also includes a reinforcing core 2. There are multiple battery cells 1, and the multiple battery cells 1 are evenly arranged around the reinforcing core 2. The battery cell 1 is used for power transmission of the cable, and at the same time, the reinforcing core 2 can effectively improve the tensile effect of the cable. A sheath 3 is sleeved outside the reinforcing core 2 and the battery cell 1. The sheath 3 facilitates the stable extrusion of the battery cell 1 and the reinforcing core 2 together, making the entire cable stable enough. A filling rope 11 is provided between the battery cell 1 and the reinforcing core 2 and between the battery cell 1 and the sheath 3; the filling rope 11 ensures sufficient stability between the battery cell 1 and the reinforcing core 2 and between the battery cell 1 and the sheath 3, and also provides a buffer during the bending process of the cable. A copper wire mesh sleeve 5 is provided outside the sheath 3, and an elastic insulating layer 4 is provided between the sheath 3 and the copper wire mesh sleeve 5. The copper wire mesh sleeve 5 is used to improve the shielding effect of the cable, and at the same time, it is convenient to improve the tensile strength of the cable. The elastic insulating layer 4 facilitates improving the bending resistance of the cable. On one side outside the copper wire mesh sleeve 5, there are a first rubber layer 6 and a second rubber layer 8, and a tensile buffer layer 7 is provided between the first rubber layer 6 and the second rubber layer 8. The first rubber layer 6 and the second rubber layer 8 facilitate clamping the tensile buffer layer 7, making the tensile buffer rope stable enough. An outer sheath 10 is provided outside the second rubber layer 8, and the outer sheath 10 is used to protect the entire cable.

[0024] As Figure 1 and Figure 2As shown, the strengthening core 2 is processed from high-strength fiber material, and the strengthening core 2 is formed by helically winding multiple strands of high-strength fiber material; this situation enables the strengthening core 2 to have sufficiently high strength even when it is relatively light in weight.

[0025] As Figure 3 shown, the battery core 1 is formed by stranding multiple strands of soft and fine copper wires, and a shielding layer 110 is provided outside the battery core 1. The shielding layer 110 and the copper wire mesh sleeve 5 can effectively improve the shielding effect of the entire cable.

The outer protective layer 10 is made of polyurethane elastomer to improve the elasticity and wear resistance of the outer protective layer 10.

[0027] Working principle: When the cable is bent during use, the internal filling rope 11 will create a certain space when being squeezed, so as to achieve the purpose of buffering the battery core 1. At the same time, the existence of the elastic insulating layer 4 also facilitates providing a good resilience force to the cable when it is bent. When the cable is subjected to tensile force, the copper wire mesh sleeve 5 and the strengthening core 2 can effectively resist the tensile force. Compared with the prior art, in this application, multiple battery cores 1 are wrapped outside the strengthening core 2, and the tensile property of the entire cable can be improved through the strengthening core 2; at the same time, a filling rope 11 is provided between the battery core 1 and the strengthening core 2 and between the battery core 1 and the sheath 3.
