Abstract

The utility model relates to a digital type conductor-pairing device for electric cable, comprising a resistor, wiring terminals with numbers and an ordinary digital multimeter. The digital type conductor-pairing device for electric cable utilizes the difference of the value of the resistor, and thus the purpose that electric cables can be conducted in pairs can be achieved according to the reading of the multimeter. The utility model has the advantages of high speed of line checking, visual display, simple structure, low cost and high reliability; the digital type conductor-pairing device for electric cable can be operated by a single person or two persons.

Description

Digital type conductor-pairing device for electric cable
The alignment device that the utility model relates to a kind of polycore cable or stranded conductor that become to prick uses when installing.
In various electrical installation works, often need carry out the lineman is done to find out the two ends of every heart yearn correspondence to polycore cable or the stranded conductor that becomes to prick.Traditional way is to search by root with multimeter or bulb, when distance is far away two ends each need a people and just can finish with telephone contact, work efficiency is very low.Chinese patent 86201702,86205321,87102192 etc. has proposed some ways that improve work efficiency, but owing to adopted matrix circuit or coding circuit, complex structure, and cost is higher and once can be to shortcomings such as the core number are less.
The purpose of this utility model is to overcome above-mentioned shortcoming, proposes the more superior alignment device of a kind of performance.
The purpose of this utility model is achieved in that it includes resistance, binding post and ordinary numbers formula multimeter or similar instrumentation etc., when the resistance that it is characterized in that being associated with on the numbered binding post different resistances uses each heart yearn of cable one end is connected on respectively on the binding post on the line connector, the other end at cable is surveyed every heart yearn, the wire size that can directly read heart yearn on multimeter with the resistance grade of ordinary numbers multimeter or similar instrumentation.
Compare with prior art, the utlity model has following advantage:
1, line inspection speed is fast, does not need to search in order, can single school line, and work efficiency can improve tens times to tens times.
2, the school core can reach 200 cores at every turn, and intuitive display, and the wire size of any single line all can show with numeral be convenient to direct-reading.
3, the fault of cable core such as short circuit, broken string, ground connection etc. all do not influence all the other normal heart yearns to line, and can differentiate failure mode from the reading on the multimeter.
4, because line connector itself without power supply, thereby is done needn't get back to the cable initiating terminal and remove powered-down after the end to the lineman, this is especially easily when cable is very long.
5, can resume classes, when any one just the heart yearn in school is with suspicion, all can resume classes, this is simple in structure, with low cost, is difficult for breaking down reliable operation.
Below in conjunction with accompanying drawing specific embodiments of the present utility model is described further:
Accompanying drawing is a wiring schematic diagram of the present utility model.
With reference to the accompanying drawings, as shown be 200 core line connector wiring diagrams, according to the resistance of the numbering among the figure by different resistances, resistance 1 be 1K Ω, resistance 2 for 2K Ω, resistance 3 for 3K Ω ... resistance 198 is that 198K Ω, resistance 199 are 199K Ω, and cooperating 3 1/2 bit digital multimeter resistance is that 200K Ω shelves use.Shown numerical value end place reading is cast out during test, and its preceding 2 1/2 place readings are core number.Allow the cable core impedance to be not more than 500 Ω.

Claims (2)

1, a kind of digital cable line connector, it includes resistance, binding post and ordinary numbers formula multimeter or similar instrumentation etc., it is characterized in that being associated with resistance on the numbered binding post.
2, digital cable line connector according to claim 1, the numerical value of the resistance that it is characterized in that linking on each binding post all is different.
