Description

Technical Field

[0001] The utility model belongs to the technical field of compensating cables, and particularly relates to a compensating conductor cable. Background Technique

[0002] A compensating cable is a special cable, mainly used to compensate for the temperature error caused by temperature change in cable connectors. The conductor material of the compensating cable is usually an alloy material, such as nickel-chromium alloy, iron-copper-nickel alloy, copper-nickel alloy, and chromium-aluminum alloy, etc. These materials have different potential responses when the temperature changes. Therefore, the potential difference can be used to measure or compensate for the temperature error;

[0003] The compensating cable is composed of a conductor, an insulating layer, a protective layer, and a casing, etc. The conductor is connected to the temperature sensor of the compensating cable and is separated by the insulating layer. The protective layer and the casing can prevent the cable from being externally interfered and improve the stability of the compensating cable.

[0004] In order to ensure the structural strength, a filling layer and the like are generally arranged inside the compensating cable to support the inside of the cable. Since the inside of the cable is a solid structure, after being compressed, the pressure will directly act on the conductor part, easily causing deformation or even fracture of the conductor. Therefore, the protection of the cable needs to be improved;

[0005] To solve the above problems, a compensating conductor cable is proposed in this application. Content of the Utility Model

[0006] The purpose of the utility model is to provide a compensating conductor cable, which solves the problems put forward in the above background technique.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model is a compensating conductor cable, including a compensating cable core. An inner support for supporting and buffering the compensating cable core is arranged at the center inside the cable. The compensating cable cores are distributed outside the inner support in multiple numbers. Supporting bars are also arranged inside the cable. The inner sides of the supporting bars support both the outside of the inner support and the compensating cable cores at the same time. The supporting bars also support between two adjacent compensating cable cores. Buffer bars are also arranged inside the cable. The buffer bars are located outside the compensating cable cores and the supporting bars. A protective layer is formed outside the buffer bars, and an insulating layer is formed outside the protective layer.

[0009] Furthermore, grooves matching with the compensating cable cores are formed outside the inner support, buffer holes are formed inside the inner support, and the compensating cable cores are circumferentially and equidistantly distributed outside the inner support through the grooves.

[0010] Further, the support bar includes a diamond-shaped bar, diamond-shaped holes provided inside the diamond-shaped bar, and first support edges symmetrically formed on both sides of the diamond-shaped bar. Second support edges are further formed on the first support edges.

[0011] Further, the outer side of the first support edge is in fitting contact with the inner side of the buffer bar, and the outer side of the second support edge is in fitting contact with the compensation cable core.

[0012] Further, a limiting groove is formed on the outer side of the inner support, and one end of the diamond-shaped bar away from the first support edge is in mutual fitting with the limiting groove.

[0013] Further, the buffer bar includes support surfaces symmetrically formed on the inner side and a buffer cavity formed inside the buffer bar. A transfer bar is provided in the buffer cavity.

[0014] Further, the transfer bar is supported on the back surface of the buffer bar in contact with the support bar on the inner side.

[0015] The utility model has the following beneficial effects:

[0016] In the utility model, buffer structures located inside the cable on the inner side of the compensation cable core and between two adjacent compensation cable cores can form a certain deformable space after the cable is externally pressed, thereby avoiding or reducing the extrusion of the compensation cable core and enabling the cable to be used reliably for a long time.

[0017] In the utility model, by arranging a support bar between the inner support and the buffer bar, the support bar can not only form a support between the two, but also form a support and play a buffering effect between the inner support and the buffer bar, improving the buffering effect while ensuring the structural strength and internal support of the cable.

[0018] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0030] Please refer to Figures 1-6 As shown, the present utility model is a compensating conductor cable, including a compensating cable core 2. An inner support 1 capable of supporting and buffering the compensating cable core 2 is arranged at the center inside the cable. The compensating cable cores 2 are distributed outside the inner support 1 in multiple numbers. A support bar 3 is also arranged inside the cable. The inner side of the support bar 3 supports both outside the inner support 1 and the compensating cable core 2, and the support bar 3 also supports between two adjacent compensating cable cores 2. A buffer bar 4 is also arranged inside the cable. The buffer bar 4 is located outside the compensating cable core 2 and the support bar 3. A protective layer 5 is formed outside the buffer bar 4, and an insulating layer 6 is formed outside the protective layer 5.

[0031] Among them, a wire groove 11 that mates with the compensation cable core 2 is formed on the outside of the inner support 1, and a buffer hole 12 is formed inside the inner support 1. The compensation cable cores 2 are circumferentially and equidistantly distributed outside the inner support 1 through the wire grooves 11. In this embodiment, the wire grooves 11 are mainly used for buffering after the positions of the cables radially facing the compensation cable cores 2 are pressed.

[0032] Among them, the support bar 3 includes a diamond-shaped bar 31, a diamond-shaped hole 32 formed inside the diamond-shaped bar 31, and first support edges 33 symmetrically formed on both sides of the diamond-shaped bar 31. Second support edges 34 are also formed on the first support edges 33. In this embodiment, the structures of the diamond-shaped bar 31 and the diamond-shaped hole 32 can play an effective buffering role after being pressed, thereby providing better protection for the compensation cable core 2.

[0033] Among them, the outside of the first support edge 33 is in close contact with the inner side of the buffer bar 4, and the outside of the second support edge 34 is in close contact with the compensation cable core 2. In this embodiment, the first support edge 33 supports the support bar 3 and the buffer bar 4, and the second support edge 34 supports the support bar 3 and the compensation cable core 2, while the diamond-shaped bar 31 and the inner support 1 achieve support, so that the support bar 3 can achieve reliable support inside the cable while having a buffering function.

[0034] Among them, a limit groove 13 is formed on the outside of the inner support 1, and one end of the diamond-shaped bar 31 away from the first support edge 33 is in close contact with the limit groove 13. In this embodiment, the limit groove 13 can improve the connection stability between the support bar 3 and the inner support 1.

[0035] Among them, the buffer bar 4 includes support surfaces 41 symmetrically formed on the inner side and a buffer cavity 42 formed inside the buffer bar 4. A transfer bar 43 is arranged in the buffer cavity 42. In this embodiment, through the contact between the support surface 41 and the compensation cable core 2, the buffer bar 4 can form support between two adjacent compensation cable cores 2, thereby ensuring the structural strength, and at the same time, the buffer bar 4 can also play a buffering effect.

[0036] Among them, the transfer bar 43 supports the back surface in contact with the support bar 3 on the inner side of the buffer bar 4. In this embodiment, the pressure received by the transfer bar 43 facing the outside of the buffer cavity 42 can be transmitted to the support bar 3 through the transfer bar 43, so as to achieve a buffering effect while ensuring reliable support of the structure.

[0037] It can be understood that first, the inner support 1, the support bar 3, and the buffer bar 4 can ensure the stable connection of the compensation cable core 2 inside the cable. At the same time, they also wrap the compensation cable core 2 inside and outside and buffer it, which can improve the buffering effect while ensuring the structural strength of the cable, making the cable more reliable and stable in use.

[0038] A specific application of this embodiment is as follows: The inner support 1 is extrusion-molded, the compensation cable core 2 is cooperatively arranged outside the wire groove 11, the support strip 3 simultaneously supports outside the inner support 1 and the compensation cable core 2, the protective layer 5 is formed outside the buffer strip 4, and the insulating layer 6 is formed outside the protective layer 5;

[0039] One end of the diamond-shaped hole 32 away from the first support edge 33 is located in the limit groove 13, the outside of the first support edge 33 is attached to the inner side of the buffer strip 4, the second support edge 34 is attached to the outside of the compensation cable core 2, the support surface 41 is attached to the outside of the compensation cable core 2, the protective layer 5 wraps the buffer strip 4, and a buffer space is formed among the inner support 1, the compensation cable core 2, and the support strip 3.
