Abstract
A simple resistance-type coaxial cable calibrating device comprises two wiring terminal tables and a circuit board. The two wiring terminal tables are welded on the circuit board, each unit of one wiring terminal table is communicated with a wiring terminal of a corresponding unit of the other wiring terminal table on a circuit through the circuit board. One wiring terminal table is used for being connected with a detection resistor while the other wiring terminal table is used for being connected with a detected cable. When calibrating cables, pluralities of detection resistors with different resistance values are selected at one end of the cable, the resistance value can be ignored when compared with resistance value of a direct current resistor of the cable, the detection resistors are fastened on a wiring terminal, and the detected cable is fastened on a wiring terminal on the other side, thereby leading the detection resistors to be serially connected into the detected cable. Resistance values of the detection resistors are recorded, and resistance values are marked on the cables connected with the detection resistors. The direct current resistors of the other ends of the cables are measured via a universal electric meter, and the cables with corresponding marks are identified when compared with the detection resistors. In addition, the simple resistance-type coaxial cable calibrating device is low in price, simple and convenient in operation and reliable in detection.

In use, one of them coupling terminal block and detection resistance are connected; The electric wire of cable is connected with another coupling terminal block.During connection, the braided wire of cable and heart yearn are inserted the connection terminal of a certain adjacent Unit two of coupling terminal block, other cables also insert and carry out mark successively, successively discern corresponding electric wire with multimeter by measuring the resistance that detects resistance at an other end, and carry out mark.Like this, do not need communication facilities, do not need two people to cooperate yet, only need a people just can finish TV the cable school line and two tasks that make marks frequently.
This correcting line machine has cable identification, cable to open circuit to detect and three kinds of functions of short-circuit detecting.
Described cable identification is in a certain engineering project, for the cable of many same structures, utilizes this correcting line machine to identify ground of cable.
Described electric wire opens circuit, and to detect be that a certain section heart yearn or the shielding line that can detect cable opens circuit, can not transmission video signal.
Described short-circuit detecting is can detection streamer internal core and shielding line short circuit, the problem that causes signal to be transmitted.
The utility model advantage is as follows:
(1) cost of manufacture is low.This correcting line machine is exactly several metal connection assemblies and plastic base, and cost can be made disposable products less than 10 yuan.
(2) user is easy to use flexibly.The employing snap fit connects, and does not need welding or screwdriver crimping; Can select the coupling terminal block of different units quantity, to adapt to one-shot measurement number of cable more conditions.
(3) detect reliably.This correcting line machine adopts resistance method of temperature measurement, can not make mistakes.
(4) adaptability is strong.As long as select the resistance value of different dimensions for use, just can survey tens meters the cables in school to tens kms.

Embodiment
This simple and easy resistance-type cable checker embodiment application principle figure as shown in Figure 1.This simple and easy resistance-type cable checker adopts the direct current resistance mensuration.The lead the same for conductive material, that length is identical, sectional area is identical, according to material Ohm law R=ρ l/S, it all is identical that its electric wire all exists direct current resistance and size, this correcting line machine is selected suitable resistance R
nThe resistance unit device be serially connected in the lead, discretize is wanted in the selection of resistance, that is to say its value otherwise with and the phase difference want big so that discern cable with corresponding resistance, in addition, the detection resistance R
nValue than the big 100-500 of direct current resistance of tested cable doubly.Like this, under lead direct current resistance and the little a lot of situation of resistance, can judge it is any wire by the resistance sizes of measuring tested wire loop.
This simple and easy resistance-type cable checker embodiment forms structure as shown in Figure 2.What two disk spring connecting-types were arranged in this correcting line machine exempts from screw type coupling terminal block A, and they all are welded on the circuit board C, and the terminals of each unit of a coupling terminal block and the corresponding unit of another coupling terminal block are communicated with by circuit board C on circuit.Circuit board C is a printed circuit board (PCB).The coupling terminal block model is 144RA-P1.
The school line method is as follows:
1, cable one end and this correcting line machine is connected
The first step: the resistance of a plurality of different resistances is inserted two adjacent connection terminals of a terminal board of correcting line machine successively, and the resistance size will make the direct current resistance of cable can ignore by comparison; Second step was that tested cable and wire is peelled off sheath, and shielding braid line and heart yearn are snapped onto two adjacent connection terminals of another one terminal board, made the detection resistance string receive in the tested cable like this; The 3rd step was to carry out mark with the number pen on corresponding cable, and write down the electricity sun value of every cable correspondence.
2, an other end school line operation steps of cable
The first step is the electric wire that detects bottom, and method is to measure that direct current resistance is R between two leads
0Electric wire.Illustrating between this two wire has one to be reference conductor, and measuring resistance then is R
0How many integral multiples, just can contrast mark, identify corresponding electric wire.
3, measure the direct current resistance of cable with multimeter, this resistance must have and have only one identical with the resistance on the record sheet, then just identified on the record sheet to cable that should resistance, on cable, carry out mark then and mark.
4, the short circuit and the detection of opening circuit: if the resistance value that records can conclude then that for infinitely great this cable opens circuit; If the resistance value that records is little, all less than selected detection resistance, even be zero, can conclude that then there is short circuit phenomenon this cable inside.
This correcting line machine has following main feature:
