Abstract
The utility model relates to a cable correction instrument, which is composed of an instrument shell, a resistor, a battery, a switch, a regulation resistance and a luminous diode. The utility model can be matched with a universal meter or a DC voltmeter for using. When the utility model is used for the cable correction, the wire connection position of two random core wires on the utility model can be determined by using the universal meter or the DC voltmeter, and light signals can display when the correction is completed. The utility model has the advantages of simple structure, fast and accurate wire correction, convenient use, convenient carrying, etc.
Description
The utility model relates to a kind of industrial cable wire device that includes watchcase, resistance, battery, switch and light emitting diode.
Now in the industrial construction cable checking the instrument of normal use be multimeter, clear one eight each heart yearn of heart yearn cable in school put in order, mode is measured in twos, needs to measure about 30 times, and is not only time-consuming but also unreliable.And have the cable checker of communication function, and need lay connection separately, use inconveniently, and investment is big.
The purpose of this utility model is to avoid outside the deficiency of prior art, and provide a kind of connection that do not need to lay separately to people, with multimeter or the supporting use of D.C. voltmeter, can in split conductor, determine the cable checking instrument of the order of any two heart yearns on the utility model at every turn, as eight core cables, it is intact to measure four schools.When using the utility model, be equipped with telecommunication equipment, as intercom, its better effects if.
The purpose of this utility model realizes by adopting following technical measures: the cable checking instrument by watchcase, be installed in resistance, the battery in the watchcase and the switch and the light emitting diode that are installed on the watchcase constitute.Resistance is divided into operating resistance and regulates resistance, operating resistance R

1Between, thereby constitute a loop.(the resistance difference between any two ends is satisfied in 1≤i≤n) and combination thereof to operating resistance Ri, and difference is bigger each other, the i.e. magnitude of voltage difference between any two ends in the loop that is to say that terminal pair constitutes funtcional relationship one to one with magnitude of voltage.Terminal is to representing that with " Da-Db " voltage of light emitting diode is reduced to E0, and expression formula is then arranged:
If E, E0, n are known, can list the corresponding tables of terminal pair and magnitude of voltage according to above-mentioned expression formula, there has been terminal pair just can carry out cable checking with the corresponding tables of magnitude of voltage.When battery E has feed slightly, regulate the resistance of resistance r, the magnitude of voltage between the terminal is remained unchanged.The utility model has n+1 terminal, promptly can connect n+1 bar heart yearn on the utility model at most at every turn.
Using method of the present utility model is as follows:
Check the cable of required school line, whether its heart yearn number is less than number of terminals of the present utility model, if, can receive an end of cable core successively on the utility model and so and carry out label in proper order by terminal of the present utility model, the other end from cable begins the school line then, with the magnitude of voltage between any two heart yearns in multimeter or the D.C. voltmeter measurement cable core, the corresponding tables of contrast terminal pair and magnitude of voltage, determine the wiring position of these two heart yearns on the utility model (be terminal to) and label, can be clear with quadrat method residual electricity conductor wire school; Article one, the cable checking available radio communication apparatus that finishes is got in touch with, if there is not communication apparatus, can the heart yearn short circuit on the head and the tail terminal of the present utility model be got up, light emitting diode on the utility model is shinny like this, hold staff of the present utility model and see that lamp is bright and will understand current cable the school is clear, need carry out next bar cable or the next item down work.If not, and the heart yearn color is identical, then needs to carry out at twice or repeatedly the school line; If cable core color difference, then can receive the heart yearn of different colours on the same terminal of the present utility model, except utilizing terminal pair distinguishes with the magnitude of voltage corresponding tables, utilize color to distinguish simultaneously during the line of school, can be clear the cable core school.
Compared with the prior art the utility model has following relatively more outstanding advantage: the cable checking method in the present industrial construction, and instrument is simple, and the school line process is trouble just, and such as multimeter school collimation method, toe-in fruit in school is also unreliable; The instrument advanced person uses inconvenience, and investment is big, has the school collimation method of the cable checker of communication function such as use.And the utility model school line is quick, accurate, and easy to operate, cost is low, approximately needs ten yuans; Instrument that the school line process is required and equipment such as multimeter or D.C. voltmeter and telecommunication equipment can be diverted to other purpose after the school line finishes, and can not cause the wasting of resources or idle.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is back panel wiring schematic diagrams of the present utility model.
Provide an embodiment of the present utility model below in conjunction with description of drawings, and the utility model is described in further detail.
The cable checking instrument that the utility model disclosed by watchcase 1, be installed in resistance, the battery 3 in the watchcase and the switch 4 and the light emitting diode 5 that are installed on the watchcase constitute.Resistance is divided into operating resistance 2 and regulates resistance 7, operating resistance R
