Description

Technical Field

[0001] The utility model relates to the technical field of cables, and more specifically to a cable which is corrosion-resistant and highly flexible. Background Art

[0002] A cable is a device for transmitting electrical energy or signals, usually consisting of several or several groups of wires.

[0003] Existing cables usually have an elastic sheath on the outside of the conductive core to avoid stress concentration when the cable is bent, thereby improving its flexibility. However, when the outer protective sheath of the cable is bent, the bent outer side of the protective sheath will be pulled. If the bending degree is too large, it is easy to cause excessive fatigue on the outside of the protective sheath, resulting in the inability to partially reset the protective sheath, causing deformation of the cable. In view of this, we propose a corrosion-resistant and highly flexible cable. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a cable that is corrosion-resistant and highly flexible, so as to solve the technical problem that when the current cable is bent, the bent outer side of the protective sheath layer is prone to excessive fatigue and cannot be reset.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a corrosion-resistant and highly flexible cable, comprising a core body, an anti-stress sleeve is arranged outside the core body, a protective sleeve layer is arranged outside the anti-stress sleeve, a plurality of groups of buffer grooves are arranged at equal intervals outside the anti-stress sleeve, a plurality of groups of arc grooves are arranged at equal intervals on the surface of the protective sleeve layer, and the arc grooves are located inside the buffer grooves;

[0006] The inner wall of the anti-stress sleeve is provided with a plurality of groups of opening grooves at equal intervals, and the opening grooves are twisted at 360 degrees.

[0007] When the utility model bends the cable, the curved outer surface of the protective sleeve layer will straighten the arc groove to meet the bending needs of the protective sleeve layer, and the deformation degree of the curved outer surface of the protective sleeve layer can be greatly improved to meet the bending needs of the cable line, and avoid the situation that the curved outer surface of the protective sleeve layer is overly fatigued and cannot be reset when the protective sleeve layer is bent, and the anti-stress sleeve is twisted from one end of the core body, and the open groove can move forward along the twisting direction of the core body, so that it can be quickly sleeved on the core body, and the raised parts between the open grooves can directly fill the gaps around the core body densely, ensuring the stability of the core body in the anti-stress sleeve.

[0008] Preferably, the core body is composed of five groups of conductive cores, and the five groups of conductive cores are twisted and wound in a 360° manner.

[0009] Preferably, the centers of the five groups of conductive cores are circular holes, and reinforcing cores are arranged in the circular holes.

[0010] Preferably, a fire-resistant layer is arranged on the outside of the conductive core, and an insulating layer is arranged on the outside of the fire-resistant layer.

[0011] Preferably, the anti-stress sleeve comprises an elastic sleeve and a ferrule, and the ferrules are arranged at equal intervals outside the elastic sleeve.

[0012] Preferably, the outer side of the protective sheath layer is coated with an anti-corrosion coating.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model distributes open grooves at equal intervals outside the anti-stress sleeve, and arranges inwardly concave arc grooves at equal intervals on the protective sleeve layer, and the arc grooves are located in the open grooves. Therefore, when the cable is bent, the curved outer surface of the protective sleeve layer will straighten the arc grooves to meet the bending requirements of the protective sleeve layer. The deformation degree of the curved outer surface of the protective sleeve layer can be greatly improved to meet the bending requirements of the cable, and the situation that the curved outer surface of the protective sleeve layer is excessively fatigued and cannot be reset when the protective sleeve layer is bent is avoided. The technical problem that the curved outer surface of the protective sleeve layer is prone to excessive fatigue and cannot be reset when the cable is bent is solved. Therefore, the utility model can be bent to a greater extent and has better flexibility.

[0015] 2. The utility model also provides an open groove on the inner wall of the anti-stress sleeve. The twisting degree of the open groove is the same as that of the conductive core. Therefore, when the anti-stress sleeve is twisted from one end of the core body, the open groove can move along the twisting direction of the core body, so that it can be quickly sleeved on the core body, and the raised parts between the open grooves can directly fill the gaps around the core body, thereby ensuring the stability of the core body in the anti-stress sleeve.

[0023] like Figures 1 to 5 As shown, the utility model relates to a corrosion-resistant and flexible cable, comprising a core body 1, an anti-stress sleeve 2 is arranged on the outside of the core body 1, a protective sleeve layer 3 is arranged on the outside of the anti-stress sleeve 2, a plurality of buffer grooves 203 are arranged at equal intervals outside the anti-stress sleeve 2, the buffer grooves 203 are in a concave form, a plurality of arc grooves 301 are arranged at equal intervals on the surface of the protective sleeve layer 3, and the arc grooves 301 are located inside the buffer grooves 203. When the cable is bent, the curved outer surface of the protective sleeve layer 3 will straighten the arc grooves 301 to meet the bending needs of the protective sleeve layer 3, and the deformation degree of the curved outer surface of the protective sleeve layer 3 can be greatly improved to meet the bending needs of the cable, thereby avoiding the situation that the curved outer surface of the protective sleeve layer 3 is excessively fatigued and cannot be reset when the protective sleeve layer 3 is bent.

[0024] Specifically, the core body 1 is composed of five groups of conductive cores 102, and the five groups of conductive cores 102 are twisted and wound in a 360-degree angle. The five groups of twisted and wound conductive cores 102 are the conductive structure of the cable.

[0025] Furthermore, the centers of the five groups of conductive cores 102 are circular holes, in which reinforcing cores 101 are arranged. The reinforcing cores 101 are used to improve the tensile strength of the cable.

[0026] Furthermore, a fire-resistant layer 103 is arranged on the outside of the conductive core 102, and an insulating layer 104 is arranged on the outside of the fire-resistant layer 103. The fire-resistant layer 103 plays a role of fire-resistant protection to prevent high-temperature spontaneous combustion, and the insulating layer 104 plays an insulating protection.

[0027] It is worth mentioning that the anti-stress sleeve 2 includes an elastic sleeve 201 and a ferrule 202. The ferrules 202 are arranged at equal intervals on the outside of the elastic sleeve 201. A buffer groove 203 is provided between two adjacent groups of ferrules 202 of the elastic sleeve 201. A contraction gap is reserved between the bottom of the arc groove 301 of the protective sleeve layer 3 and the elastic sleeve 201 so that the inner side of the protective sleeve layer 3 can continue to retract when bent. When the cable is bent to a certain extent, the two adjacent groups of ferrules 202 touch each other to prevent further bending, so as to avoid damage to the cable due to excessive bending.

[0028] It is worth mentioning that the outer side of the protective sleeve layer 3 is coated with an anti-corrosion coating 4, which plays an anti-corrosion protection role.

[0029] In an embodiment of the utility model, a plurality of groups of open grooves 204 are evenly spaced on the inner wall of the anti-stress sleeve 2, and the open grooves 204 are twisted 360°. The open grooves 204 should match the conductive core 102. Therefore, the anti-stress sleeve 2 is twisted from one end of the core body 1, and the open grooves 204 can move along the twisting direction of the core body 1, so that it can be quickly put on the core body 1, and the raised parts between the open grooves 204 can directly fill the gaps around the core body 1 densely, thereby ensuring the stability of the core body 1 in the anti-stress sleeve 2.

[0030] Working principle: This embodiment provides a cable with corrosion resistance and strong flexibility. When the cable is bent, the curved outer surface of the protective sheath layer 3 will straighten the arc groove 301 to meet the bending requirements of the protective sheath layer 3, which can greatly improve the deformation degree of the curved outer surface of the protective sheath layer 3 to meet the bending requirements of the cable and avoid the situation where the curved outer surface of the protective sheath layer 3 is excessively fatigued and cannot be reset when the protective sheath layer 3 is bent;

[0031] Secondly, a shrinkage gap is reserved between the bottom of the arc groove 301 of the protective sleeve layer 3 and the elastic sleeve 201, so that the inner side of the protective sleeve layer 3 continues to retract when it is bent, and when the cable is bent to a certain extent, the two groups of adjacent rings 202 touch each other to prevent further bending, so as to avoid damage to the cable due to excessive bending.

[0032] Finally, the anti-stress sleeve 2 is twisted from one end of the core body 1, and the open groove 204 can move along the twisting direction of the core body 1, so that it can be quickly put on the core body 1, and the raised parts between the open grooves 204 can directly fill the gaps around the core body 1 tightly, ensuring the stability of the core body 1 in the anti-stress sleeve 2.

[0033] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
