Description

Technical Field

[0001] The present application relates to the field of cables, and in particular to an aluminum alloy cable. Background Art

[0002] Aluminum alloy cable is a new type of power cable made of aluminum alloy as conductor. Its bending performance, creep resistance and corrosion resistance are greatly improved compared with pure aluminum cable.

[0003] At present, the Chinese utility model patent with patent announcement number CN217955466U has announced a highly flexible fireproof and wear-resistant corrosion-resistant control cable, including a cable core, and a metal shielding layer, a metal fireproof layer, a fireproof oxygen-isolating layer and an outer sheath arranged from the inside to the outside of the cable core; the metal fireproof layer is a ring-shaped concentric corrugated structure. This solution greatly improves the flexibility of the cable by forming the internal metal fireproof layer with a stainless steel ring-shaped concentric corrugated structure; at the same time, the stainless steel sheath fireproof layer can also play an anti-oxidation and anti-corrosion role, further greatly improving the stability of the fireproof cable during operation.

[0004] When cables need to be connected, the cable end faces must be cut first, and then the outer sheath is removed with a cutter. During the removal process, the cutter can easily damage the cable core, rendering part of the cable body unusable, which can easily lead to a decrease in the transmission quality of the cable core. Utility Model Content

[0005] In order to reduce the occurrence of damage to the cable core during cutting of the outer sheath, the present application provides an aluminum alloy cable.

[0006] The present application provides an aluminum alloy cable, which adopts the following technical solution:

[0008] By adopting the above technical solution, when the cables need to be docked, the staff first cuts the end face of the cable to expose the cable core, filling block, support frame, outer sheath and driving member. The staff operates the driving member, and the driving member drives the ejector rod to move. The ejector rod abuts against the inner wall of the outer sheath and ejects the outer sheath, and separates the outer sheath from the support frame. The staff can use a tool to cut through the protruding part. Even if the tool cuts deeper, it only contacts the support frame, reducing the contact of the tool with the cable core during cutting, thereby improving the cutting accuracy of the tool.

[0010] By adopting the above technical solution, the support plates are distributed around the support tube, so that the support tube is evenly stressed, the support plates are convenient for supporting the outer sheath, and the reliability of the support frame is improved.

[0011] Optionally, the ejection assembly includes a plurality of ejection rods, the plurality of ejection rods correspond one-to-one to the plurality of support plates, the ejection rods are slidably connected to the support plates, the driving member includes a driving wheel, the driving wheel is coaxially arranged with the support tube, the driving wheel is rotatably connected to the side wall of the support tube, a plurality of guide grooves are provided on the side wall of the driving wheel, the plurality of guide grooves correspond one-to-one to the plurality of ejection rods, one end of the ejection rod is located in the guide groove, and the guide groove is used to guide the ejection rod to move toward the inner side wall of the outer protective layer.

[0012] By adopting the above technical solution, when it is necessary to bring the ejector rod into contact with the outer sheath, the staff can rotate the driving wheel, and the ejector rod, under the guidance of the guide groove, moves toward the outer sheath until the outer sheath is pushed off the support frame, and a bulge can be observed on the outer wall of the outer sheath, which is convenient for the staff to cut the outer sheath, and even if the staff drops the knife heavily, the tool will only cut the support frame, thereby reducing the damage to the cable core, and the driving component has a simple structure, which is convenient for the staff to operate.

[0013] Optionally, both end surfaces of the driving wheel are provided with cross slots adapted for a cross screwdriver.

[0014] By adopting the above technical solution, the cross slot allows the staff to operate the driving wheel with a cross screwdriver, which is easy to operate.

[0015] Optionally, a limit block is provided on the side wall of the ejector rod, a sliding groove is opened on the support plate, the limit block is located in the sliding groove, an elastic block is also provided in the sliding groove, and the elastic block is used to keep the ejector rod away from the outer protective layer.

[0016] By adopting the above technical solution, the limit block reduces the random movement of the ejector rod, and only when the staff operates it will the limit block be driven to move toward the outer protective layer, thereby improving the wrapping of the outer protective layer when there is no need to peel off the outer protective layer.

[0017] Optionally, a plurality of annular grooves are formed on the outer protective layer, and the plurality of annular grooves and the plurality of ejection assemblies are arranged alternately.

[0018] By adopting the above technical solution, the annular groove makes it easy for the staff to identify the position of the ejection assembly. The staff can determine the end face cutting position through the position of the annular groove. The end face cutting position does not affect the ejection assembly. The annular groove improves the reliability of the ejection assembly.

[0019] Optionally, there is a gap between adjacent driving wheels.

[0020] By adopting the above technical solution, there is a gap in the driving wheel, which reduces the damage to the driving wheel when the cable end face is cut, making it easier for subsequent staff to operate the driving wheel.

[0021] Optionally, the cable core includes a cable, an insulating protective layer and a metal shielding layer, the insulating protective layer covers the cable, and the metal shielding layer covers the cable.

[0022] By adopting the above technical solution, the provided insulating protective layer can protect the cables, and the provided metal shielding layer can reduce interference between multiple cables.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The ejector assembly is convenient for separating the outer sheath and the support frame, making it easier for workers to cut the outer sheath and reduce damage to the cable core during the cutting process. BRIEF DESCRIPTION OF THE DRAWINGS
