Description

Technical Field

[0001] The present application belongs to the field of cable technology, and in particular relates to a control cable capable of reducing corner wear effects. Background Art

[0002] Although the cross-sectional area of ​​the control cable is small, it has many cores and is generally used to transmit control signals.

Different models have different scopes of use.

[0003] When laying control cables, they often encounter some corners of walls or cable trays. The cables are easily damaged when they are worn against the corners of walls or cable trays for a long time, which damages the cables, reduces the service life of the control cables, and causes economic losses.

[0006] Preferably, the fixing bolt is a butterfly bolt.

[0007] Therefore, the worker can fix and disassemble the clamping component without using tools.

[0008] Preferably, the wear-resistant cloth is made of wear-resistant canvas.

[0010] Preferably, the length direction of the thickened wear-resistant strip is consistent with the length direction of the cable body.

[0011] When the wear-resistant cloth is wrapped, the thickened wear-resistant strip is arranged on the side where the cable body turns, thereby enhancing the wear resistance of the cable at the corner.

[0012] Preferably, the shielding layer is made of braided copper wire.

[0013] Preferably, the number of the control cores is greater than 20.

[0014] There are more control cores, so the cable body of the present application can be compatible with a wider range of devices and has better applicability.

[0015] Beneficial effects:

[0016] 1. The control cable of the present application which can reduce the effect of corner wear has a wear-resistant layer provided on the outermost layer of the cable, thereby enhancing the wear resistance of the cable.

[0017] 2. The wear-resistant cloth is set at the contact point between the cable and the corner of the wall or the corner of the cable tray through two clamping components, so as to prevent the cable body from being worn by the wall or the cable tray, thereby affecting the service life of the cable.
