Description

Technical Field

[0001] The present invention relates to the field of cable technology, and in particular to an A-cavity and B-cavity cable assembly. Background Art

[0002] The current cable structure is generally composed of multiple core wires, and each core wire is then protected by an external wrapping layer. Therefore, once this type of cable is squeezed, all the core wires will be squeezed and damaged, resulting in a greatly reduced service life of the entire cable. The cable has poor compression and shear resistance, poor elasticity, and is difficult to recover from deformation. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention provides an A and B cavity cable assembly, and the specific technical solution is as follows:

[0004] An A and B cavity cable assembly, comprising:

[0005] Cable core parts;

[0006] A plurality of groups of elastic blocks are arranged at intervals along the length direction of the cable core member, and two groups of cavities for placing the cable core member are opened on the elastic block. A hose for liquid flow is fixedly inserted inside the elastic block and between the two groups of cavities. The hose connects the plurality of groups of elastic blocks in series. When the cable is subjected to compression pressure, the hose is controlled to deform to make room for the cable core member to avoid.

[0007] In the above technical solution, a connector is electrically connected to the cable, and the connector is divided into cavity A and cavity B, which can ensure that only cable core parts of the same type can be correctly connected, thereby preventing incorrect connection. When the cable is in a normal state, the elastic block can provide elastic support to the cable core parts, maintain the stability of the cable core parts, prevent the cable core parts from shifting or deforming when the external environment changes or during use, and ensure the normal operation and performance of the cable. When the cable is subjected to extrusion force, the elastic block is deformed, which will cause the hose to deform as well, thereby freeing up avoidance space for the cable core parts and effectively avoiding damage to the cable core. At the same time, due to the support of the elastic block, the cable core parts can be quickly restored after the external pressure is withdrawn, so that the cable has good compression and bending resistance characteristics, avoiding damage to the cable during use. The cable core parts are arranged in different cavities. When subjected to shear force, the cable core parts will not be damaged due to mutual squeezing, and the arrangement state of the cable core parts can be maintained.

[0008] As an improvement of the above technical solution, an elastic ring is sleeved in the cavity and on the surface of the cable core component, a storage cavity is opened in the elastic ring, and a connecting hole is provided between the storage cavity and the hose. When the cable is subjected to compressive pressure, the hose is controlled to deform, and the liquid in the hose can flow into the storage cavity to exchange heat with the elastic ring, thereby improving the heat dissipation effect of the cable core component.

[0009] In the above technical solution, when the cable is subjected to compressive pressure, the hose will be deformed, so that the liquid in the hose enters the storage cavity of the elastic ring under the action of the extrusion pressure, so that the liquid in the storage cavity exchanges heat with the elastic ring, thereby taking away the heat on the elastic ring, and when the external pressure is removed, the hose recovers under the action of the restorative elastic force of the elastic block, and the liquid inside the elastic ring flows under the action of the internal pressure, thereby realizing the flow of the liquid in the elastic ring, thereby further improving the heat dissipation effect of the cable core.

[0010] As an improvement of the above technical solution, the cross-sectional shape of the hose includes two groups of arc-shaped portions 1 protruding outward and an arc-shaped portion 2 connecting the two groups of arc-shaped portions 1 and recessed inward, and the connecting hole is arranged at the arc-shaped portion 2.

[0011] As an improvement of the above technical solution, the hose includes a connecting pipe connecting two adjacent groups of elastic blocks, and two groups of sealing members are arranged on the connecting pipe, and a sealing area is formed between the two groups of sealing members.

[0012] As an improvement of the above technical solution, the sealing member includes a pressing portion arranged on the connecting tube, a fixing ring is arranged on the outer surface of the pressing portion, an elastic member is arranged between the fixing ring and the pressing portion, and the elastic force of the elastic member acts on the pressing portion to control the inner wall of the pressing portion to form a linear contact.

[0013] As an improvement of the above technical solution, the elastic member includes a plurality of groups of springs arranged on the inner wall of the fixing ring and an arc-shaped plate arranged between the springs and the pressing portion.

[0014] As an improvement of the above technical solution, it also includes a wrapping layer, which includes a filling layer, a shielding layer and a protective layer from the inside to the outside.

[0015] Beneficial effects of the present invention:

[0016] When the cable is subjected to extrusion pressure, the elastic block is deformed, which causes the hose to deform as well, thus freeing up space for the cable core components and effectively preventing damage to the cable core. At the same time, due to the support of the elastic block, the cable can quickly recover after the external pressure is removed, so that the cable has good compression and bending resistance, thus preventing the cable from being damaged during use. The cable core components are arranged in different cavities. When subjected to shear force, the cable core components will not be damaged due to mutual squeezing and the arrangement state of the cable core components can be maintained.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] A cable assembly with A and B cavities comprises: a cable core 40; a plurality of groups of elastic blocks 20, wherein the plurality of groups of elastic blocks 20 are arranged at intervals along the length direction of the cable core 40, the elastic blocks 20 are provided with two groups of cavities for placing the cable core 40, a hose 21 for liquid flow is fixedly inserted inside the elastic block 20 and between the two groups of cavities, the hose 21 connects the plurality of groups of elastic blocks 20 in series, and when the cable is subjected to compression pressure, the hose 21 is controlled to deform to make room for the cable core 40 to avoid.

[0023] The cable is electrically connected to a connector 60, which is divided into an A cavity and a B cavity, to ensure that only cable core members 40 of the same type can be correctly connected, thereby preventing incorrect connection. In a normal state, the elastic block 20 can provide elastic support to the cable core member 40, maintain the stability of the cable core member 40, prevent the cable core member 40 from shifting or deforming when the external environment changes or during use, and ensure the normal operation and performance of the cable. When the cable is subjected to extrusion force, the elastic block 20 is deformed, which will cause the hose 21 to deform as well, thereby freeing up avoidance space for the cable core member 40 and effectively avoiding damage to the cable core. At the same time, due to the support of the elastic block 20, the cable can be quickly restored after the external pressure is removed, so that the cable has good compression and bending resistance characteristics, avoiding damage to the cable during use. The cable core members 40 are arranged in different cavities. When subjected to shear force, the cable core members 40 will not be damaged due to mutual squeezing, and the arrangement state of the cable core members 40 can be maintained.

[0024] Since the heat dissipation performance of cables is relatively general, refer to Figure 2 , an elastic ring 30 is sleeved in the cavity and on the surface of the cable core 40, a storage cavity is opened in the elastic ring 30, and a connecting hole 22 is arranged between the storage cavity and the hose 21. When the cable is subjected to a compressive pressure, the hose 21 is controlled to be deformed, and the liquid in the hose 21 can flow into the storage cavity to exchange heat with the elastic ring 30, thereby improving the heat dissipation effect of the cable core assembly. Specifically, the heat of the cable core 40 can be conducted to the elastic ring 30. When the cable is subjected to a compressive pressure, the hose 21 will be deformed, so that the liquid in the hose enters the storage cavity of the elastic ring 30 under the action of the extrusion force, so that the liquid in the storage cavity exchanges heat with the elastic ring 30, thereby taking away the heat on the elastic ring 30, and when the external pressure is withdrawn, the hose 21 is restored under the action of the restorative elastic force of the elastic block 20, and the liquid in the elastic ring 30 will flow under the action of the internal pressure, so as to realize the flow of the liquid in the elastic ring 30, thereby further improving the heat dissipation effect of the cable core.

[0025] In order to prevent the hose 21 from being completely squeezed, refer to Figure 2 The cross-sectional shape of the hose 21 includes two groups of arc-shaped portions 211 protruding outward and an arc-shaped portion 212 connecting the two groups of arc-shaped portions 211 and recessed inward. The connecting hole 22 is arranged at the arc-shaped portion 212. Specifically, when the cable is squeezed, the two groups of arc-shaped portions 212 recessed inwardly will abut against each other, so that the two groups of arc-shaped portions 211 respectively enclose channels for storing liquid, so as to avoid excessive squeezing force, resulting in excessive liquid pressure in the hose 21, thereby causing the hose 21 to rupture.

[0026] To facilitate cable cutting, refer to Figure 3The hose 21 includes a connecting tube 23 connecting two adjacent groups of elastic blocks 20. Two groups of seals are arranged on the connecting tube 23. A sealing area is formed between the two groups of seals. When the cable needs to be cut, the cutting point can be within the sealing area, so that the liquid at both ends of the hose 21 is not easy to flow out, and the sealing of the hose 21 is convenient.

[0027] In one embodiment, reference Figure 3 The sealing member includes a pressing portion 231 arranged on the connecting tube 23, and a fixing ring 50 is arranged on the outer surface of the pressing portion 231. An elastic member is arranged between the fixing ring 50 and the pressing portion 231, and the elastic force of the elastic member acts on the pressing portion 231 to control the inner wall of the pressing portion 231 to form a line contact. Specifically, when it is necessary to transport liquid into the hose 21, when the liquid passes through the pressing portion 231, when the liquid pressure is greater than the elastic force of the elastic member, the pressing portion 231 opens, so that the liquid enters the hose 21 or the connecting tube 23 through the pressing portion 231. When the liquid pressure is less than the elastic force of the elastic member, the pressing portion 231 is in a line contact state, that is, a sealing state, so that the liquid will not flow out. On the one hand, it is convenient to cut the cable so that the liquid is not easy to leak. On the other hand, the hose 21 in each group of elastic blocks 20 can be filled with liquid to ensure the liquid pressure in each group of hoses 21.

[0028] In one embodiment, reference Figure 3 The elastic member includes multiple groups of springs 51 arranged on the inner wall of the fixing ring 50 and an arc plate 52 arranged between the springs 51 and the pressing portion 231. The shape of the arc plate 52 matches the shape of the pressing portion 231. The elastic force of the spring 51 acts on the pressing portion through the arc plate 52 to evenly distribute the elastic force on the surface of the pressing portion 231, reduce local pressure, and avoid damage to the pressing portion 231 caused by excessive local force. The springs 51 are distributed in a ring shape in the fixing ring 50.

[0029] In one embodiment, reference Figure 2 , and also includes a wrapping layer, which includes a filling layer 12, a shielding layer 11 and a protective layer 10 from the inside to the outside. The filling layer 12 can completely wrap the elastic block 20 and the cable core member 40, and can be made of a cross-linked polyethylene polymer material with a fire retardant effect. The shielding layer 11 is woven from metal wires, which can be one of copper or aluminum, and the protective layer 10 is woven from propylene fiber material.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
