Anti-damage wiring outlet device

Abstract

The invention provides an anti-damage wiring outlet device, and relates to electric wires. The anti-damage wiring outlet device can provide the minimum bending radius for the line to reduce the damage of the bending to the stress concentration site of the line and effectively prolong the service of cable accessories. The anti-damage wiring outlet device is funnel-shaped and is provided with a device internal corner, a device bottom through hole, an electric wire and a device external corner; the device internal corner is a right angle, the device external corner is a circular bead, the circular bead radius of the device external corner is at least twice as large as the diameter of the electric wire; and the device bottom through hole is in clearance fit with the electric wire, and a flexible protection layer is arranged between the device bottom through hole and the electric wire.

Description

technical field [0001] The invention relates to electric wires and cables, in particular to an anti-breakage wiring outlet device. Background technique [0002] As we all know, wires and cables are widely used in various fields of industry or civil use, such as earphone cables, chargers, communication cables, data cables, etc. For a long time, during the use of existing wires and cables, the number of times the wires and cables are often generated , Large-scale bending and folding phenomenon, the bending and folding will generate stress on the wire and cable, the stress acts on the wire, shielding layer and built-in wire, even if the stress is less than the plastic yield point, fatigue deformation or even fracture will occur. The most common type of cable break failure is the eventual break of the cable's shield or conductor in the bend area. If the shield fails first, the wire may continue to function normally, but the cable will be susceptible to EMI / RFI interference. Thi...

Problems solved by technology

[0003] In the past 20 years, many wire and cable enthusiasts and technicians have explored and researched the device and design of wire and cable anti-breakage, such as the bending-resistant long-life wire designed by Liu Wenyu in Beijing (see Chinese patent CN201120430762.7 ), and an anti-breakage cable connector designed by Xu Zhiyong of Inner Mongolia and an earphone including the breakage-proof cable connector (see Chinese patent CN201620334895.7), etc., most of which stay in the model stage, and the reality more difficult to achieve
