Description

Technical Field

[0001] This application relates to the field of cables, and more specifically, to a compression-resistant cable. Background Technology

[0002] A cable is a device for transmitting electrical energy or signals, typically composed of several or several groups of conductors. That is, it usually contains several or several groups of cable cores. Cables are commonly found in daily life and production, and there are many types, including power cables, control cables, compensating cables, shielded cables, and signal cables.

[0003] In traditional cable technology, the entire cable is wrapped with a soft structure (such as rubber), making the cable relatively soft. The cable lacks an effective anti-compression structure, and when the cable is compressed, the cable core inside is also easily compressed, which can easily lead to excessive deformation of the cable core and low safety. Utility Model Content

[0004] To overcome the above deficiencies, this application provides an anti-extrusion cable, which aims to improve the problem that the cable core is prone to excessive deformation when the cable is subjected to extrusion.

[0005] This application provides an anti-crush cable, including a cable body.

[0006] The cable body includes a central rod, support rods, a wire mesh sleeve, a first arc-shaped support plate, cable cores, and second arc-shaped support plates. Several support rods are provided, with one end of each support rod fixedly connected to the central rod. The wire mesh sleeve is fixedly fitted onto the other end of each support rod. Several first arc-shaped support plates are provided, each fixedly connected between two adjacent support rods. Each first arc-shaped support plate is connected to the inner wall of the wire mesh sleeve. Several cable cores are provided, each corresponding to one of two adjacent support rods. Second arc-shaped support plates are provided on both sides of each cable core, with one end of each second arc-shaped support plate fixedly connected to a support rod and the other end fixedly connected to the first arc-shaped support plate.

[0007] In one specific implementation, a first waterproof layer is provided on the outside of the wire mesh sleeve, the first waterproof layer being a polyurethane material layer.

[0008] In one specific implementation, a protective sleeve is provided on the outside of the first waterproof layer, and the protective sleeve is a layer of polyethylene material.

[0009] In one specific implementation, a plurality of the support rods are evenly distributed in a circular pattern, and a connecting plate is provided at one end of each of the support rods away from the central rod. The connecting plates are fixedly connected to the inner wall of the wire mesh sleeve, and the connecting plates are evenly distributed in a circular pattern.

[0010] In one specific implementation, reinforcing blocks are provided on both sides of several of the support rods, and the reinforcing blocks are fixedly connected to the inner wall of the first arc-shaped support plate.

[0011] In one specific implementation, several first arc-shaped support plates are evenly distributed in a circular pattern, and a shielding layer is fixedly provided on the outer wall of the several first arc-shaped support plates, the shielding layer being composed of an electromagnetic shielding film.

[0012] In one specific implementation, a second waterproof layer is provided on the outside of the shielding layer, and the second waterproof layer is a polyvinyl chloride material layer.

[0013] In one specific implementation, the outer wall of the second waterproof layer is provided with a heat insulation layer, which is an aerogel heat insulation material layer.

[0014] In one specific implementation, a support block is provided on the outer wall of each of the first arc-shaped support plates. The support block is fixedly inserted through the shielding layer, the second waterproof layer and the heat insulation layer, and the support block is fixedly connected to the inner wall of the wire mesh sleeve.

[0015] Beneficial effects: This application provides a compression-resistant cable. In use, the steel wire mesh sheath provides compression resistance. The central rod can provide primary support to the steel wire mesh sheath through several support rods. These support rods also support several first arc-shaped support plates, which in turn provide secondary support to the steel wire mesh sheath. This ensures the compressive strength of the steel wire mesh sheath, protects the cable core, and prevents the cable core from being squeezed or excessively deformed, resulting in high safety.

Several support rods 120 are provided, and one end of each support rod 120 is fixedly connected to the rod body of the central rod 110. The support rods 120 are evenly distributed in a circular pattern.

[0022] In this embodiment, the wire mesh sleeve 130 is fixedly sleeved on the other end of several support rods 120. Each of the several support rods 120 is provided with a connecting plate 121 at the end away from the central rod 110. Several connecting plates 121 are fixedly connected to the inner wall of the wire mesh sleeve 130. The several connecting plates 121 are evenly distributed in a circumferential manner.

[0023] In a specific implementation plan, a first waterproof layer 131 is provided on the outside of the wire mesh sleeve 130. The first waterproof layer 131 is a polyurethane material layer. A protective sleeve 170 is provided on the outside of the first waterproof layer 131. The protective sleeve 170 is a polyethylene material layer.

[0024] In a specific configuration, several first arc-shaped support plates 140 are provided, and several first arc-shaped support plates 140 are fixedly connected between two adjacent support rods 120 respectively. The two ends of the first arc-shaped support plate 140 are fixedly connected to the two support rods 120 respectively.

[0025] In this application, reinforcing blocks 122 are provided on both sides of several support rods 120. The reinforcing blocks 122 are fixedly connected to the inner wall of the first arc-shaped support plate 140. Several first arc-shaped support plates 140 are evenly distributed in a circumferential pattern. A shielding layer 141 is fixedly provided on the outer wall of several first arc-shaped support plates 140. The shielding layer 141 is composed of an electromagnetic shielding film. A second waterproof layer 142 is provided on the outside of the shielding layer 141. The second waterproof layer 142 is a polyvinyl chloride material layer.

[0026] In this embodiment, the outer wall of the second waterproof layer 142 is provided with a heat insulation layer 143, which is an aerogel heat insulation material layer. Several first arc-shaped support plates 140 are connected to the inner wall of the wire mesh sleeve 130.

[0027] In a specific implementation plan, a plurality of cable cores 150 are provided, and the plurality of cable cores 150 are respectively located between two adjacent support rods 120.

[0028] Specifically, the working principle of this compression-resistant cable is as follows: During use, the polyethylene protective sleeve 170 provides primary protection, the first waterproof layer 131 of polyurethane provides primary waterproofing, and the steel wire mesh sleeve 130 provides compression resistance. The central rod 110 provides primary support to the steel wire mesh sleeve 130 through several support rods 120 and connecting plates 121. The support rods 120 also support several first arc-shaped support plates 140. The first arc-shaped support plates 140 provide secondary support to the steel wire mesh sleeve 130 through support blocks 144, thereby ensuring the compressive strength of the steel wire mesh sleeve 130, thus protecting the cable core 150, making the cable core 150 less susceptible to compression, and preventing excessive deformation of the cable core 150, resulting in high safety. Furthermore, the shielding layer 141 provides electromagnetic shielding to the cable core 150, the second waterproof layer 142 provides secondary waterproofing to the cable core 150, and the heat insulation layer 143 provides heat insulation protection to the cable core 150.
