Description

Technical Field

[0001] The present invention relates to the technical field of branch cables, and in particular to a composite low-voltage branch cable. Background Art

[0002] Branch cable is a cable used to connect the distribution network of electrical equipment. It is widely used in construction, industry and other places that require power distribution. Its main feature is that the branch line is pre-manufactured on the trunk cable, which greatly shortens the construction period, reduces material cost and construction cost, and ensures the reliability of power distribution. The branch cable is composed of several parts: trunk cable, branch line and branch connector, etc. The trunk cable has a larger cross-sectional area to meet the power demand. The trunk cable and the branch line are connected by the branch connector set on the trunk cable to ensure the stability of power transmission. The power is transmitted to the electrical equipment through the branch cable. By manufacturing the cable branches in advance, pre-branched cables are manufactured. The pre-branched cables can be used directly when cable branches are needed, which improves the sealing and stability of the cable branches.

[0003] A composite low-voltage branch cable is a cable that combines power transmission and fiber-optic communication functions. It is widely used in smart grids, power fiber-to-the-home and other fields. It is designed to improve the efficiency and reliability of power distribution, while supporting high-speed data transmission to meet the dual needs of modern society for power and communication. The power transmission cable in the composite low-voltage cable is usually composed of copper or aluminum conductors. When power transmission branches are required, the specifications and quantity of the conductors may vary according to different power requirements. Each conductor is wrapped with an insulating layer, and the conductors can be selected for branching according to needs. However, due to the diversity of conductors, only one conductor can be branched on the traditional branch cable. This requires preparing multiple branch cables, or the branch cable will be equipped with a branch line for each conductor, which will cause waste, and the branch on the branch cable is large in size and not conducive to installation. Therefore, in order to make branching more convenient when using composite low-voltage cables for power transmission branches, we have proposed a composite low-voltage branch cable.

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 7 As shown, this embodiment proposes a composite low-voltage branch cable, including a composite cable 1, in which multiple conductors 2 of different sizes are provided, and also includes a branch area 3, a conductor support mechanism, a connecting wire 4, an insulating sheath 5 and a docking clamping mechanism. The branch area 3 is opened on the composite cable 1, and multiple conductors 2 are exposed in the branch area 3. The conductor support mechanism is fixedly arranged in the branch area 3, and the conductor support mechanism is detachably connected to the multiple conductors 2. The conductor support mechanism is used to support and fix the conductor 2. There are multiple connecting wires 4, which correspond one-to-one to the conductors 2. The connecting wires 4 and the conductors 2 are detachably connected through the conductor support mechanism. The insulating sheath 5 is sleeved on the branch area 3, and the insulating sheath 5 is connected to the insulating layer on the composite cable 1. There are multiple docking clamping mechanisms, which correspond one-to-one to the conductors 2. The docking clamping mechanism is arranged on the insulating sheath 5. The branch line 6 is detachably connected to the docking clamping mechanism. The docking clamping mechanism is used to detachably connect the branch line 6 to the connecting wire 4. In this embodiment, there are three conductors 2, and the diameters of the three conductors 2 are different.

[0028] like Figures 1 to 4 As shown, the conductor support mechanism includes a clamping conductive component and a conductor fixing component. There are multiple clamping conductive components, and the multiple clamping conductive components are staggered in the branch area 3. The clamping conductive component is detachably connected to the conductor 2. The clamping conductive component is used to clamp the conductor 2 and the connecting line 4, wherein the portion of the conductor 2 in contact with the clamping conductive component has an insulation layer removed. The conductor fixing component is arranged in the branch area 3. The conductor fixing component is detachably connected to the multiple conductors 2. The conductor fixing component is used to fix the multiple conductors 2. The clamping conductive component includes a C-type clamp 1 7, an insulating plate 8 and a C-type clamp 2 9. The C-type clamp 1 7 is arranged between the multiple conductors 2.

Since the conductor 2 needs to be conductive, the surface insulation layer is peeled off, and the part of the conductor 2 with the stripped insulation layer is separated from the other conductors 2 by the insulating plate 8 to prevent the parts of the stripped insulation layer of multiple conductors 2 from contacting each other. The staggered arrangement of multiple clamping conductive components makes the branch positions on the cable far away from each other, avoiding the proximity of multiple branch lines 6, making the branch position larger in volume, affecting the installation position.

[0029] like Figure 3~Figure 4 As shown, the conductor fixing assembly includes a positioning piece 10, an anti-twist rod 11 and a clamping piece 12. There are multiple positioning pieces 10, which are detachably connected to multiple wires 2. Multiple positioning pieces 10 are spaced apart from the clamping conductive assembly.

Clamping pieces 12 are set on both sides of the positioning piece 10. Since the fillers between the insulating sheath of the cable and the wires 2 are removed in the branch area 3, in order to prevent the three wires 2 from twisting, the positioning piece 10 fixes the three wires 2 to avoid mutual contact between the wires 2. The anti-twist rod 11 is set to a T-shape. The anti-twist rod 11 passes through four positioning pieces 10. The positioning piece 10 is clamped and fixed to the torsion rod by the clamping piece 12. Bolts are set on the clamping piece 12, and the torsion rod is squeezed and fixed by rotating the bolts.

[0030] like Figures 5 to 7 As shown, the docking clamping mechanism includes a branch frame 13, a docking frame 14, a conduction component and a crimping component. The branch frame 13 is fixedly arranged on the insulating sheath 5. The branch frame 13 corresponds to the clamping conduction component one by one. The branch frame 13 is sleeved on the clamping conduction component. The docking frame 14 is fixedly arranged on the docking frame 14. The branch line 6 is detachably connected to the docking frame 14. The conduction component is fixedly arranged in the docking frame 14. The conduction component is connected to the connecting line 4. The conduction component conducts electricity between the branch line 6 and the conductor 2. There are two crimping components, which are arranged opposite to each other. The crimping components are fixed. It is fixedly arranged in the docking frame 14, and the crimping assembly is detachably connected to the branch line 6.

There are three branch frames 13, and the three branch frames 13 are staggered on the insulating sheath 5. The branch frame 13 is arranged around the insulating sheath 5 to avoid the large volume of the branch caused by too many wires 2. The branch frame 13 is used to protect the clamping conduction assembly. When connecting the branch line 6, the branch line 6 is extended into the docking frame 14, and the branch line 6 is connected to the conduction assembly through the crimping assembly, so that the branch line 6 is docked with the connecting line 4.

[0031] like Figures 5 to 7As shown, the conduction component includes a socket 15 and a plug 16, the socket 15 is fixedly arranged in the docking frame 14, the socket 15 is connected to the connecting line 4, the plug 16 is fixedly arranged on the branch line 6, and the plug 16 is detachably connected to the socket 15, and the crimping component includes a docking hole 17, a slide rail frame, a clamping frame 19, a sliding column 20 and an adjusting component, the docking hole 17 is provided on the docking frame 14 at a position aligned with the socket 15, there are two slide rail frames, the two slide rail frames are fixedly arranged in the docking frame 14, an F-shaped F slide rail 18 is provided on the slide rail frame, the clamping frame 19 is slidably arranged between the two slide rail frames, a push pin 25 is provided on the clamping frame 19 at one end close to the socket 15, a clamping ring 26 is provided on the clamping frame 19 at one end away from the push pin 25, two sliding columns 20 are fixedly arranged on each side of the clamping frame 19, the sliding column 20 is slidably arranged in the F slide rail 18, the adjusting component is provided on the docking frame 14, the docking frame 14 It is used to adjust the sliding position of the clamping frame 19 on the F slide rail 18.

After the plug 16 is docked with the socket 15 through the docking hole 17, the plug 16 is fixed and driven by the clamping frame 19. When the clamping frame 19 slides on the F slide rail 18 through the sliding column 20, the clamping frame 19 first moves obliquely until the sliding column 20 slides to the straight section on the F slide rail 18. At this time, the pushing pin 25 extends into the slot, and the clamping ring 26 contacts the branch line 6. At this time, the sliding of the clamping frame 19 pushes the pin 25 to push the socket 15 into the plug 16 through the slot, and drives the sealing ring 24 to move toward the docking hole 17, so that the sealing ring 24 is squeezed into the docking hole 17 to achieve sealing. For unused branches, a plug similar to the branch line 6 and the socket 15 can be extended into the docking frame 14, and docked through the clamping frame 19 for sealing.

One end of the screw 21 passes through the docking frame 14. The screw 21 can be twisted by a screwdriver. When the screw 21 rotates, the pushing piece 22 will deflect a certain angle in the pushing groove 23 as the screw 21 deflects. The pushing piece 22 will push the clamping frame 19 to move, and because the pushing piece 22 is in the pushing groove 23, the clamping frame 19 will not deflect, and the clamping frame 19 will always maintain a parallel state and move in the F slide rail 18.

[0033] In this embodiment, in the branch area 3 on the composite cable 1, the insulation layers of different conductors 2 are stripped at different positions, the connecting wire 4 and the conductor 2 are clamped by C-type clamp 1 and C-type clamp 2, and the anti-twist rod 11 passes through the positioning piece 10 to prevent the conductor 2 from twisting. For the branch cable that needs to be used, one end of the plug 16 on the branch line 6 is inserted into the docking hole 17. After the plug 16 is docked with the socket 15, a screwdriver is used to turn the screw 21, and the screw 21 drives the pushing piece 22 to move.
