Description

Technical Field

[0001] This utility model relates to the field of cable and wire technology, specifically to a conductor with gaps filled throughout the entire conductor core. Background Technology

[0002] Cables are typically rope-like electrical wires composed of several or groups of conductors (at least two conductors per group) twisted together. Each group of conductors is insulated from the others and is often twisted around a central core, with the entire structure covered by a highly insulating outer layer. Cables generally require a round appearance, so filler is added to the gaps inside the conductors. For electrical products with very high requirements for roundness, the roundness of the cable core is crucial.

[0003] Currently, most existing conductors with gap filling are circular and filled in the gaps, resulting in a small contact area with the conductor. When the cable is compressed, the conductor will rub against the filler conductor, causing displacement. Furthermore, displacement and friction will also occur between the conductors, leading to poor overall stability. Therefore, we propose a conductor with full-length through-core gap filling. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a conductor with full-length, through-core gap filling, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a conductor with full-length through-core gap filling, comprising a filling conductor body and a cable, wherein a fitting sleeve is provided on the outer side of the filling conductor body, a conical head is provided on the top of the fitting sleeve, an arc-shaped surface is provided on the top of the conical head, core fitting surfaces are provided on both sides of the conical head, an inner arc-shaped fitting surface is provided on the bottom of the fitting sleeve, and a support surface is provided on both sides of the fitting sleeve.

[0006] Preferably, the cable has a core body inside, and there is a gap to be filled inside the cable and outside the core body. The filling conductor body and the fitting sleeve are fitted with the gap to be filled.

[0007] Preferably, the conical head, the arc surface, and the core-fitting surface all mate with the core body.

[0008] Preferably, the inner arc-shaped mating surface mates with the inner wall of the cable.

[0009] Preferably, the filler conductor body includes a nylon core, a ceramic fiber layer is disposed on the outside of the nylon core, a flame-retardant composite layer is disposed on the outside of the ceramic fiber layer, and a wear-resistant material layer is disposed on the outside of the flame-retardant composite layer.

[0010] This utility model provides a conductor with gaps filled throughout the entire conductor core, which has the following beneficial effects:

[0011] 1. The conductor with gap filling throughout the entire conductor core, through the setting of fitting sleeve, conical head, arc surface, conductor fitting surface, inner arc fitting surface and supporting surface, can increase the fitting area with the conductor core body, and after filling, it will also improve the stability of several conductor core bodies and avoid displacement of conductor core bodies and friction.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figures 1 to 3 This utility model provides a technical solution: a conductor with full-length through-core gap filling, comprising a conductor body 1 and a cable 2. A fitting sleeve 3 is provided on the outer side of the conductor body 1. A conical head 4 is provided on the top of the fitting sleeve 3. An arc-shaped surface 5 is provided on the top of the conical head 4. Core fitting surfaces 6 are provided on both sides of the conical head 4. The conical head 4, the arc-shaped surface 5, and the core fitting surfaces 6 all cooperate with the core body 9. An inner arc-shaped fitting surface 7 is provided at the bottom of the fitting sleeve 3. The inner arc-shaped fitting surface 7 cooperates with the inner wall of the cable 2. Supporting surfaces 8 are provided on both sides of the fitting sleeve 3. The conical head 4, the arc-shaped surface 5, and the core fitting surfaces 6 facilitate the filling of the conductor body 1 and the fitting sleeve 3 into the nylon core 11 and position the filling positions of several core bodies 9.

[0018] The cable 2 has a core body 9 inside, and there is a gap 10 to be filled inside the cable 2 and outside the core body 9. The filling conductor body 1 and the fitting sleeve 3 cooperate with the gap 10 to be filled.

[0019] The filler conductor body 1 includes a nylon core 11, a ceramic fiber layer 12 is disposed on the outside of the nylon core 11, a flame-retardant composite layer 13 is disposed on the outside of the ceramic fiber layer 12, and a wear-resistant material layer 14 is disposed on the outside of the flame-retardant composite layer 13. The ceramic fiber layer 12 is used to improve the toughness of the filler conductor body 1, and the flame-retardant composite layer 13 can prevent it from burning.

[0020] In summary, when using this conductor with full-length through-core gap filling, after the filling conductor body 1 is filled into the gap 10 to be filled, the conical head 4 can be positioned at the middle of the outer side of the two core bodies 9, and the core contact surface 6 is attached to the surface of the core body 9 to make it stable. When the cable 2 is squeezed, it can avoid the displacement and friction of several core bodies 9.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
