Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to an easy-to-install protective isolation cable. Background Technology

[0002] In existing technologies, in addition to the cable core used for signal transmission, cables sometimes need to have various skeleton structures inside to protect the cable core, such as some skeleton structures that are resistant to pressure and bending, as well as skeleton mechanisms with heat dissipation and water cooling functions.

[0003] For example, the technical solution disclosed in the public announcement (CN206774264U) is a “comprehensive control cable resistant to crushing”. In this technical solution, a solid skeleton structure is set inside to increase the crushing capacity. The skeleton structure can prevent the individual cable cores from crushing each other.

[0004] For example, the technical solution disclosed in Publication No. CN212411664U, entitled "A Multimedia Digital Communication Cable with an Internal Skeleton," features four independently configured internal skeletons of the same shape and size. Each internal skeleton includes a flat skeleton and arc-shaped skeletons on both sides of the flat skeleton. Two of the flat skeletons have sleeves installed on their inner ends, while the other two flat skeletons have corresponding sleeves installed on their inner ends. The arc-shaped skeletons on both sides of each flat skeleton are shaped to fit together. In this device, the internal skeletons are configured as four that can be assembled. The inner ends of the flat skeletons are used to install the sleeves and sleeves for assembly, while the arc-shaped skeletons at both ends of the flat skeletons form a placement area for the signal cable core after assembly. Thus, when the four internal skeletons are assembled, a heat dissipation and ventilation channel for the cable core is formed inside, enabling the entire cable to have ventilation and heat dissipation functions.

[0005] The skeleton in the above technical solution can enable the overall cable to have better heat dissipation function; however, in the specific field of cable technology, if a skeleton structure is set, sometimes the skeleton setting will make the installation of the cable core inconvenient, and the cable core cannot be easily embedded in the position; in addition, in the existing technology, after the cable core is installed by the skeleton, it is still exposed to the outside, rather than being protected by the skeleton as a whole; and even if it is protected by the skeleton as a whole, the cable core inside is squeezed together instead of being isolated, which can still lead to damage when the cable core is squeezed, which is not worth the loss.

[0006] Therefore, in order to solve the above problems, it is necessary to develop an easy-to-install protective isolation cable with a reasonable structure that can effectively protect the internal cable core. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing an easy-to-install protective isolation cable; the technical solution is as follows:

[0008] An easy-to-install protective isolation cable includes an internal protective frame and a first cable core and a second cable core mounted on the protective frame. The protective frame includes a central shaft frame and corresponding plate frames mounted on the shaft frame. Several plate frames are provided, each configured as an arc-shaped plate structure. The plate frames are evenly spaced and correspondingly mounted on the shaft frame, with installation areas for the first and second cable cores between adjacent plate frames. The first and second cable cores are correspondingly positioned within these installation areas.

[0009] Furthermore, after the first and second cable cores are respectively installed in the installation area, a wrapping layer is also provided on the outside. The wrapping layer wraps the cable cores and the overall protective skeleton inside and is wrapped into a cable. An outer shielding layer is also provided outside the wrapping layer, and an outer sheath is also provided outside the outer shielding layer.

[0010] Furthermore, the plate frame is provided with six evenly spaced sections, and there are also six corresponding installation areas. The first cable core and the second cable core are installed in the six installation areas respectively.

[0011] Furthermore, the first cable core and the second cable core are respectively arranged on the inner and outer circumferences of the installation area, with the first cable core installed on the inner circumference and the second cable core installed on the outer circumference; the first cable core and the second cable core are respectively arranged on the two circumferences.

[0012] Furthermore, the side wall of the plate frame is provided with an insert groove corresponding to the position of the first cable core and the second cable core; the insert groove is configured as an arc-shaped groove structure, and the first cable core and the second cable core are installed in the insert groove respectively.

[0013] Furthermore, the outer end of the plate frame is set with an arc-shaped profile, and the size of the second cable core located on the outer side is set accordingly, so that the position of the second cable core matches the arc-shaped profile of the outer end of the plate frame, and then the cable is wrapped by the outer wrapping layer.

[0014] Furthermore, the gap between the mounting area of ​​the plate frame and the first and second cable cores is filled with fiber material.

[0015] Furthermore, both the first cable core and the second cable core include an innermost conductor, an insulation layer outside the conductor, an inner shielding layer outside the insulation layer, and an outer sheath outside the inner shielding layer.

[0016] Beneficial effects: This utility model has the following beneficial effects:

[0017] 1) In this device, the plate skeleton is evenly distributed on the shaft skeleton, thus forming an installation area of ​​the same size between adjacent plate skeletons. The first cable core and the second cable core can be set in the installation area accordingly. Then, the entire structure is wrapped into a cable by the outer wrapping layer. The first cable core and the second cable core are thus protected between the inner plate skeletons. Therefore, when subjected to external pressure, due to the protection of the plate skeleton, the inner first cable core and the second cable core will not be subjected to great pressure, thus protecting the cable cores.

[0018] 2) In this device, additionally, there are mounting grooves on the side wall of the plate frame that correspond to the positions of the first cable core and the second cable core. The first cable core and the second cable core are placed in the mounting grooves, which makes the overall installation of the cable cores very convenient. Furthermore, the first cable core and the second cable core are set separately, and the cable cores in adjacent installation areas are also set separately, which can effectively protect the cable cores. When the cable cores are squeezed, there will be no situation where the cable cores are pressed together, thus achieving isolation between the cable cores and making the structural design more reasonable.

Detailed Implementation

[0024] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an easy-to-install protective isolation cable includes an internal protective frame and a first cable core 1 and a second cable core 2 installed on the protective frame. The protective frame includes a central shaft frame 3 and plate frames 4 correspondingly installed on the shaft frame 3. Several plate frames 4 are provided, each configured as an arc-shaped plate structure. The plate frames 4 are evenly spaced and correspondingly installed on the shaft frame 3, with an installation area 5 between adjacent plate frames 4 for installing the first cable core 1 and the second cable core 2. The first cable core 1 and the second cable core 2 are correspondingly located within the installation area 5.

[0026] Furthermore, the first cable core 1 and the second cable core 2 are respectively arranged after the installation area 5, and a wrapping layer 6 is also provided on the outside. The wrapping layer 6 wraps the cable core and the overall protective skeleton inside and is correspondingly wrapped into a cable. An outer shielding layer 7 is also provided on the outside of the wrapping layer 6, and an outer sheath 8 is also provided on the outside of the outer shielding layer 7.

[0027] The plate frame 4 has six evenly spaced sections, and there are also six corresponding installation areas 5. The first cable core 1 and the second cable core 2 are installed in the six installation areas 5 respectively.

[0028] The first cable core 1 and the second cable core 2 are respectively arranged on the inner and outer circumferences of the installation area 5. The first cable core 1 is installed on the inner circumference, and the second cable core 2 is installed on the outer circumference. The first cable core 1 and the second cable core 2 are respectively arranged on the two circumferences.

[0029] The plate frame 4 has an insert groove 9 on its side wall that corresponds to the position of the first cable core 1 and the second cable core 2; the insert groove 9 is an arc-shaped groove structure, and the first cable core 1 and the second cable core 2 are installed in the insert groove 9.

[0030] The outer end of the plate frame 4 is set with an arc-shaped profile, and the size of the second cable core 2 located on the outer side is set accordingly, so that the position of the second cable core 2 is adapted to the arc-shaped profile of the outer end of the plate frame 4, and then the cable is wrapped by the outer wrapping layer 6.

[0031] The gap between the mounting area 5 of the plate frame 4 and the first cable core 1 and the second cable core 2 is filled with fiber material 10.

[0032] The first cable core 1 and the second cable core 2 both include an innermost conductor 11, an insulation layer 12 outside the conductor 11, an inner shielding layer 13 outside the insulation layer 12, and an outer sheath 8 outside the inner shielding layer 13.

[0033] In the technical solution of this utility model, the cable is provided with an internal skeleton, which includes a central shaft skeleton and a plate skeleton mounted on the shaft skeleton. The shaft skeleton is mainly used as a main shaft, and the extension direction of the shaft skeleton is consistent with the direction of the cable. The plate skeleton is used to install the first cable core and the second cable core.

[0034] The plate frame is evenly distributed on the shaft frame, so that an installation area of ​​the same size is formed between adjacent plate frames. The first cable core and the second cable core can be set in the installation area accordingly. Then, the entire structure is wrapped into a cable by the outer wrapping layer, and the first cable core and the second cable core are protected between the inner plate frames.

[0035] With this configuration, when subjected to external pressure, the first and second cable cores inside will not be subjected to significant pressure due to the protection of the plate frame, thus protecting the cable cores.

[0036] Furthermore, this device also features additional mounting slots on the side walls of the plate frame, corresponding to the positions of the first and second cable cores. By placing the first and second cable cores in these slots, the overall installation of the cable cores becomes very convenient. Moreover, the first and second cable cores are set separately, and the cable cores in adjacent installation areas are also set separately, which effectively protects the cable cores. When the cable cores are squeezed, there will be no situation where the cable cores are pressed together, thus achieving isolation between the cable cores and making the structural design more reasonable.
