Scalable electric wire marker tie

Abstract

The invention relates to the professional technical field of relay protection, in particular to a retractable wire identification cable tie, including a Velcro I (1) and a Velcro II (2), and is characterized in that: the Velcro I (1) and the Velcro II (2) A section of elastic bandage (3) is arranged between them to be connected to each other, and an identification plate (4) is arranged at one end of the Velcro I (1) away from the Velcro II (2). One end of the Velcro II (2) of I (1) is provided with a cable tie loop (5), the front and back sides of the Velcro I (1) are provided with nylon hook surfaces, and the positive and negative sides of the Velcro II (2) are provided with nylon hooks. The opposite sides and the outer surface of the cable tie loop (5) are provided with nylon wool surfaces that can be sucked and engaged with the nylon hook surfaces. The invention can adapt to different wire diameters, can keep the binding of the cable ties firm and not fall under any circumstances, and also has the function of marking, which greatly improves the safety and convenience of relay protection professionals.

Description

technical field [0001] The invention relates to the technical field of relay protection, in particular to a stretchable electric wire marking cable tie. Background technique [0002] Relay protection professionals need to connect multiple current and voltage signal test lines, sometimes as many as 20 or more, between the test instrument and the equipment test terminals when performing equipment calibration such as protection, measurement, and safety. There is no special place for test wires behind the equipment screen cabinet. The test is messy and confusing, and it is easy to confuse the wiring. At the same time, the test wire is very long and has a certain weight. It is easy to make the clamp on the test terminal fall off, and the test personnel often waste on wiring. Many times, if the clamp falls off during the test, it will pose a safety threat to the test instrument, protective device or staff.

There is no special place for test wires behind the equipment screen cabinet. The test is messy and confusing, and it is easy to confuse the wiring. At the same time, the test wire is very long and has a certain weight. It is easy to make the clamp on the test terminal fall off, and the test personnel often waste on wiring. Many times, if the clamp falls off during the test, it will pose a safety threat to the test instrument, protective device or staff

[0003] Most of the cable ties currently on the market are made of plastic material, designed with a backstop function, which can only be tightened and tightened, and cannot be loosened. They are disposable and cannot be used repeatedly

[0004] In the prior art, Velcro is also used to bind wires. This kind of fixed-length Velcro will not fit wires with different diameters, and the cable tie has no marking function, so it cannot be used for testing wires. For classification and identification, the existing method is to paste a sticky note on the cable tie by yourself, which is troublesome. If the place of the paste is wrong, it will not meet the current safety regulations.
