Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cable with an anti-breaking structure. Background Art

[0002] Cable is a general term for optical cables, electrical cables and other items. The main uses of cables include controlling installation, connecting equipment, transmitting electricity and other multiple functions. They are common and indispensable equipment in daily life. Cables are bent during the production, transportation, laying and use of cables. Cables are at risk of being over-bent during the bending process. The risks of excessive bending of cables include: first, causing the outer insulation layer of the cable to loosen or even break; second, causing the wire core to become thinner due to tension, thereby increasing the resistance and heat of the cable; third, causing excessive stress inside the cable, thereby increasing the speed of cable aging;

[0003] In the patent document with publication number CN220604390U, a new type of base station communication cable is disclosed, including multiple twisted pair cores, the surfaces of the multiple twisted pair cores are wrapped with a sheath together, a filling rope is arranged in the gap between the twisted pair cores and inside the sheath, the surface of the sheath is wrapped with a shielding layer, and the surface of the shielding layer is wrapped with a first insulating layer. The cable in the above patent document has a certain bending resistance through the filling rope, but its bending strength is limited. In actual use, the filling rope is prone to plastic deformation or being pulled apart, thereby reducing the bending resistance of the cable. When the bending angle is too large, the core will be compressed and bent, which may cause the aforementioned risks;

[0004] Therefore, it is necessary to improve the existing cables with respect to the above defects. Utility Model Content

[0005] In order to solve the problem that the outer insulation layer and the original structure of the core of the cable will be damaged when the cable is bent at an excessive angle during use, so that the protective function of the outer insulation layer is affected and the shape of the core is damaged, the present application provides a cable with an anti-breakage structure.

[0006] The utility model provides a cable with an anti-breaking structure adopts the following technical solution:

[0007] A cable with an anti-breaking structure comprises an outer insulating layer, a wire core, and an anti-breaking component, wherein the anti-breaking component comprises an anti-breaking piece, wherein the outer insulating layer is sleeved on the outside of the wire core, and the anti-breaking piece is arranged in multiple groups, wherein the multiple groups of anti-breaking pieces are sequentially arranged on the inner side of the outer insulating layer along the axis of the wire core, and when the cable is bent, the axes of two adjacent groups of anti-breaking pieces are arranged at an angle and the two groups of anti-breaking pieces are abutted against each other.

[0008] Preferably, the anti-bending member is arranged in a strip shape, and one end surface of the anti-bending member is provided with a chamfer.

[0009] Preferably, the chamfer is 45 degrees.

[0026] The following will be combined with the attached Figure 1-7 The utility model is further described with examples.

[0027] This embodiment discloses a cable with an anti-breaking structure.

[0028] Since the existing cables are bent during transportation and use, if the bending angle is too large, the outer insulation layer and the original structure of the core 13 of the cable will be damaged, thereby affecting the protection function of the outer insulation layer. At the same time, the core 13 will also be reduced in cross section due to bending, thereby increasing the heat generation and even causing disconnection. In order to solve the above problems, reference is made to Figure 1-7 The present embodiment discloses a cable with an anti-breaking structure, including an outer insulating layer 11, a wire core 13, and an anti-breaking component. The outer insulating layer 11 is located at the outermost side of the cable to protect and insulate, and the wire core 13 plays a role in conducting electricity and transmitting data. The anti-breaking component includes an anti-breaking piece 32. The outer insulating layer 11 is sleeved on the outer side of the wire core 13. The anti-breaking piece 32 is arranged in multiple groups. The multiple groups of anti-breaking pieces 32 are arranged in sequence on the inner side of the outer insulating layer 11 along the axis of the wire core 13. When the cable is bent, the axes of two adjacent groups of anti-breaking pieces 32 are arranged at an angle and the two groups of anti-breaking pieces 32 abut against each other. Specifically, the cable is bent to a certain angle, and the angle varies depending on the model of the cable. Adjacent anti-breaking pieces 32 will abut against each other, thereby producing a blocking effect on the continued increase in the bending angle of the cable, reducing the risk of the cable being excessively bent, thereby reducing the risk of the wire core 13 being deformed or disconnected.

[0029] Specifically, this embodiment also includes an inner insulating layer 12, which is provided in multiple groups. The multiple groups of inner insulating layers 12 are arranged in a circular array on the inner side of the outer insulating layer 11, and the multiple groups of inner insulating layers 12 are all embedded with a wire core 13, and the outer insulating layer 11 is sleeved on the outer side of the inner insulating layer 12.

[0030] When adjacent anti-bending members 32 rotate relative to each other and abut against each other, the bottom edge of one anti-bending member 32 may abut against the top surface of another anti-bending member 32. In this case, the line-surface contact occurs. If the bottom edge is damaged or worn, the rotation angle limited by the anti-bending component will increase, thereby increasing the risk of excessive bending of the wire core 13. To solve the above problem, Figure 7 In the present embodiment, the anti-folding member 32 is provided in a strip shape, and a chamfer 33 is provided on one end face of the anti-folding member 32. The angle of the chamfer 33 is set according to the bending angle that the cable needs to limit. When adjacent anti-folding members 32 abut against each other, the chamfer 33 of one anti-folding member 32 will abut against the top surface of the anti-folding member 32, so that the contact between the anti-folding members 32 is surface-to-surface contact, thereby increasing the force-bearing parts when adjacent anti-folding members 32 abut against each other and reducing the possibility of wear when the anti-folding members 32 abut against each other.

[0031] Preferably, the chamfer 33 is 45 degrees. When adjacent anti-bending members 32 abut against each other, the chamfer 33 set at 45 degrees can make the angle of the axes of the adjacent anti-bending members 32 when abutting against each other be approximately 135 degrees, and the angle of 135 degrees is the middle value of an obtuse angle. Using this angle as the angle of the adjacent anti-bending members 32 can reduce the possibility of the wire core 13 being bent into a right angle. The wire core 13 bent into a right angle will increase the possibility of the wire core 13 being deformed or broken, so the above setting reduces the possibility of the wire core 13 being deformed or broken.

[0032] It should be noted that the manufacturer can change the length of the anti-bending member 32 and increase the number of anti-bending members 32 of cables of the same length, thereby changing the bendable angle of the cables of the same length.

[0033] If the positions of adjacent anti-folding parts 32 are close to each other, it will affect the preset bendable angle of the anti-folding component. In order to improve the position stability between each anti-folding part 32, the anti-folding component of this embodiment also includes a connecting strip 34. The anti-folding part 32 is provided with a through hole. The axial direction of the through hole is parallel to the axial direction of the anti-folding part 32. The connecting strip 34 passes through the through holes of multiple groups of anti-folding parts 32 in sequence. The annular wall protrusion of the connecting strip 34 is provided with a limiting portion 36. The limiting portion 36 is located at both ends of the anti-folding part 32. The limiting portion 36 is used to limit the distance between adjacent anti-folding parts 32. Through the above arrangement, the limiting portion 36 reduces the possibility that adjacent anti-folding parts 32 will be close to each other, improves the position stability of the anti-folding part 32, and improves the stability of the preset bendable angle of the anti-folding component.

[0034] The anti-folding member 32 of the present embodiment is made of polyether ketone or polyphenylene sulfide, both of which are insulating, high temperature resistant, chemically resistant, and rigid. During the use of the cable, it may be in a high temperature environment, an environment susceptible to corrosion, an environment susceptible to forces, or adjacent anti-folding members 32 may be in a state of abutting each other. Setting the raw material of the anti-folding member 32 to polyether ketone or polyphenylene sulfide can improve the stability of the anti-folding member 32 in the above-mentioned environment or state.

[0035] This embodiment also includes a support body 14, an outer insulating layer 11 is sleeved on the outside of the support body 14, and the wire core 13, the inner insulating layer 12, and the anti-bending member 32 are embedded in the support body 14. The support body 14 prevents the wire cores 13 and the anti-bending member 32 from being squeezed, misaligned or damaged by each other. The support body 14 reduces the risk of the wire core 13 and the anti-bending member 32 being mechanically damaged by the outside. The support body 14 also plays an insulating role to improve the insulation between the wire cores 13 and improve the stability of the cable.

[0036] When the cable is bent, the inner side of the bent portion of the cable will be squeezed, and the squeezed support body 14 and outer insulating layer 11 will be squeezed into the inside of the cable. When the outer insulating layer 11 is squeezed inward, if the support body 14 does not give way to it, the outer insulating layer 11 will be inflated, resulting in the thickness of the outer insulating layer 11 becoming thinner. In order to solve the above problem, the anti-bending member 32 of the present embodiment is arranged in a round strip shape, and a frustum portion 37 is provided on both sides of the anti-bending member 32. Through the above arrangement, when the cable is bent, the space left by the frustum portion 37 reserves a position for the inward extrusion of the support body 14, thereby reducing the possibility that the support body 14 will squeeze the outer insulating layer 11, reduce the possibility that the outer insulating layer 11 will be inflated, and reduce the possibility that the outer insulating layer 11 will become thinner.

[0037] The outer ring wall of the truncated cone portion 37 of the anti-bending member 32 of this embodiment is an inwardly concave arc setting. Through the above setting, the volume of the space left by the truncated cone portion 37 is further increased, thereby increasing the space for the support member.

[0038] During the use of the cable, the connecting strip 34 may be in a high temperature environment, an environment susceptible to corrosion, and an environment susceptible to the influence of forces. At the same time, the connecting strip 34 may bend due to the bending of the cable. Therefore, in this embodiment, the raw material of the connecting strip 34 is set to fluoroplastic. Fluoroplastic has high temperature resistance, chemical corrosion resistance, insulation, toughness and elasticity. The connecting strip 34 is made of fluoroplastic to improve the stability of the connecting strip 34 during use.

[0039] Preferably, the raw material used for the connecting strip 34 of this embodiment is polytetrafluoroethylene.

[0040] The anti-breaking components of the present embodiment are arranged in one or more groups. When multiple groups are arranged, the axis of at least one group of anti-breaking components is coincident with the axis of the wire core 13, and the axes of the remaining groups of anti-breaking components are distributed in a circular array around the axes of the wire core 13. The axes of the anti-breaking components are parallel to the axis of the cable. Multiple groups of anti-breaking components are all embedded in the support body 14. Through the multiple groups of anti-breaking components, when one group of anti-breaking components breaks, the remaining anti-breaking components can still play an anti-breaking role, thereby improving the anti-breaking stability of the cable.

[0041] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
