Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a cable that is easy to bundle. Background Technology

[0002] Cables are typically rope-like cables made up of several or groups of conductors (at least two conductors per group) twisted together. Each group of conductors is insulated from each other and is often twisted around a central core. The entire cable is covered with a highly insulating outer layer. Cables are characterized by being energized internally and insulated externally. During cable laying, multiple cables need to be bundled together.

[0003] A search revealed a Chinese patent (application number "202020565262.3") disclosing "A Power Cable for Easy Bundling." This power cable includes a conductive core, an insulating sleeve fitted onto the outer side of the conductive core, a shielding aluminum foil layer wound around the outer side of the insulating sleeve, a thermal insulation cotton layer covered on the outer side of the shielding aluminum foil layer, and a rubber sleeve fitted onto the outer side of the thermal insulation cotton layer. The rubber sleeve has two or more annular limiting grooves processed on its annular side, and a front retaining ring and a rear retaining ring are fitted onto the annular limiting grooves. The front retaining ring is positioned in front of the rear retaining ring, and its bottom end is integrally connected to the bottom end of the rear retaining ring. However, when bundling two or more sets of cables, this power cable requires using retaining rings to cover the cables and then using retaining springs for fixation. This bundling process involves numerous steps, making it difficult to quickly bundle the cables and resulting in low practicality. Utility Model Content

[0004] This utility model provides a cable that is easy to bundle, solving the problem proposed in the prior art that when bundling two or more sets of power cables, it is necessary to use clips to cover the cables and then use spring clips to fix them. This involves many bundling steps, making it impossible to quickly bundle the cables and resulting in low practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cable designed for easy bundling includes three copper cores. Each of the three copper cores has an inner insulation layer, and a retainer is provided between the three inner insulation layers. A shielding layer is provided outside the retainer, and a buffer layer is provided outside the shielding layer. An armor layer is provided outside the buffer layer, and an outer insulation layer is provided outside the armor layer. A bundling layer is provided outside the outer insulation layer. The bundling layer includes a flame-retardant outer layer. A plurality of alternately distributed limiting bosses and positioning bosses are provided on the outer wall of the flame-retardant outer layer. A first bundling groove is formed on the outer wall of each of the limiting bosses, and a second bundling groove is formed on the outer wall of each of the positioning bosses.

[0006] Preferably, the three copper cores are each made of several copper wires twisted together, and three inner insulating layers are respectively wrapped around the outer wall of the three copper cores.

[0007] Preferably, the outer wall of the retainer has three arc-shaped grooves, and the three inner insulating layers are respectively bonded to the three arc-shaped grooves.

[0008] Preferably, the inner wall of the shielding layer abuts against the outer walls of the three inner insulating layers, and the three spaces formed by the shielding layer, the retainer, and the three inner insulating layers are all filled with filler.

[0009] Preferably, the buffer layer covers the outer wall of the shielding layer, and the armor layer covers the outer wall of the buffer layer, while the outer insulating layer covers the outer wall of the armor layer.

[0010] Preferably, the flame-retardant outer layer, several limiting bosses, and several positioning bosses are integrally extruded and formed, and the flame-retardant outer layer covers the outer wall of the outer insulation layer. The width of the limiting bosses is adapted to the width of the positioning bosses, the width of the first binding groove is adapted to the width of the second binding groove, and several anti-slip grooves are opened on the inner walls of the first binding groove and the second binding groove.

[0011] With the above scheme, the two cables are staggered during bundling, so that the limiting boss on one cable is located between the two limiting bosses on the other cable. At this time, the outer wall of the limiting boss on one cable is in contact with the outer wall of the positioning boss on the other cable. Then, the cable tie is put into the first bundling groove and the second bundling groove, thereby realizing the rapid bundling of the two cables.

[0012] The beneficial effects of this utility model are as follows: During bundling, the two cables are staggered so that the limiting protrusion on one cable is positioned between the two limiting protrusions on the other cable. At this time, the outer wall of the limiting protrusion on one cable is in contact with the outer wall of the positioning protrusion on the other cable. Then, the cable tie is placed in the first bundling groove and the second bundling groove, thereby realizing the rapid bundling of the two cables. It can position the two cables during bundling, prevent the cables from moving relative to each other, and can quickly bundle the cables, thus improving practicality. Attached Figure Description

[0018] 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.

[0019] Example 1, referring to Figure 1 and Figure 4 A cable that is easy to bundle includes three copper cores 1, each composed of several copper wires twisted together. Each of the three copper cores 1 is covered with an inner insulation layer 2. A retainer 3 is provided between the three inner insulation layers 2. Three arc-shaped grooves are opened on the outer wall of the retainer 3. The three inner insulation layers 2 are respectively bonded to the three arc-shaped grooves. A shielding layer 4 is provided outside the retainer 3. The inner wall of the shielding layer 4 abuts against the outer wall of the three inner insulation layers 2. The three spaces formed by the shielding layer 4, the retainer 3 and the three inner insulation layers 2 are all filled with filler. A buffer layer 5 is covered outside the shielding layer 4. An armor layer 6 is covered outside the buffer layer 5. An outer insulation layer 7 is covered outside the armor layer 6.

[0020] Example 2, refer to Figure 2-3 A cable that is easy to bundle also includes a bundling layer 8. The bundling layer 8 includes a flame-retardant outer layer 81. The outer wall of the flame-retardant outer layer 81 is provided with a plurality of alternately distributed limiting bosses 82 and positioning bosses 84. The outer wall of the plurality of limiting bosses 82 is provided with a first bundling groove 83, and the outer wall of the plurality of positioning bosses 84 is provided with a second bundling groove 85. The flame-retardant outer layer 81, the plurality of limiting bosses 82 and the plurality of positioning bosses 84 are integrally extruded and formed. The flame-retardant outer layer 81 covers the outer wall of the outer insulation layer 7. The width of the limiting bosses 82 is adapted to the width of the positioning bosses 84. The width of the first bundling groove 83 is adapted to the width of the second bundling groove 85. The inner walls of the first bundling groove 83 and the second bundling groove 85 are provided with a plurality of anti-slip grooves.

[0021] Working principle: During bundling, the two cables are staggered so that the limiting protrusion 82 on one cable is located between the two limiting protrusions 82 on the other cable. During bundling, the positioning protrusion 84 keeps a certain distance between the two cables to avoid electromagnetic interference between them. At this time, the outer wall of the limiting protrusion 82 on one cable is in contact with the outer wall of the positioning protrusion 83 on the other cable. Then, the cable tie is placed in the first bundling groove 83 and the second bundling groove 85, thereby realizing the rapid bundling of the two cables.
