One end of cable core is connected with the terminals of terminal box, and arbitrarily the other end of two core cable heart yearn connects the common port of line connector main frame respectively and to line end;
The power source voltage value is the M milliampere divided by the merchant of the resistance between the common bus of the M terminals of terminal box and terminal box, M≤N.
In one example, also be serially connected with zero-regulator resistor between power supply and the digital milliammeter; The power source voltage value is the M milliampere divided by the resistance between the common port of the M terminals of terminal box and terminal box and the merchant of zero-regulator resistor resistance sum.
In one example, be with the wire size pipe on the cable core.
In one example, the resistance between the common bus of the terminals of terminal box and terminal box is adjustable resistance.
The utility model can be checked the corresponding situation of cable two ends heart yearn apace.
Description of drawings
Come the utility model is done further explain below in conjunction with accompanying drawing, wherein:
Fig. 1 is the terminal box schematic diagram;
Fig. 2 is the main frame key wiring diagram.
Embodiment
The utility model provides a simple and practical device to realize the checking of cable core, and has overlapped wire size at an end of cable, inserts terminal box arbitrarily; Carry out record; Choose a core cable arbitrarily at the other end and link to each other as the common port of common port with the line connector main frame, other heart yearns one by one with the line connector main frame to line end overlap joint, can numeral show the numbering on the pairing offside terminal box of this heart yearn; Put corresponding wire size, promptly accomplished the work of core Line To Line.
The cable core line connector is made up of terminal box and line connector main frame two parts, and behind the high precision adjustable resistance Rw and diode D parallel connection of terminal box by some different resistances, an end is attempted by on the common bus; The other end is drawn the jack that is connected to terminal box; Compiling coding 1 on the jack of terminal box in order to N, the quantity of terminal box jack can determine according to actual needs that mostly cable generally commonly used is the 4-12 core; This instance adopts 10 core jacks, and the principle of terminal box is as shown in Figure 1; Nixie display mainly is made up of power unit and digital milliammeter and zeroing loop.
During use, after required paired cable offside has overlapped the wire size pipe with the heart yearn of this cable arbitrarily, insert the terminals jack of terminal box, write down numbering and the corresponding relation of wire size on the terminal box; Opposite side at cable; Get any core cable and be connected with the common port 21 of host box, all the other heart yearns appoint get one of which and host box to line end 22 overlap joint, the numeral that shows on the host box is the numbering on the terminal box; Put corresponding wire size pipe; Promptly accomplished the checking work of a core, repeated this step, remaining at last numbering promptly is the pairing numbering of common port.In the time of to line, also accomplished basic check to this cable core conduction.
As shown in Figure 1, the wiring of terminal box is very simple, after a high precision adjustable resistance and general-purpose diode parallel connection, connect together, quantity how much determined disposable can be to what of heart yearn.Host box mainly is made up of a power supply and a digital milliammeter, and power supply can adopt the powered battery of two joint 15V.When the quantity that increases terminal connection parallel connection element when increasing the disposable quantity of checking heart yearn, for guaranteeing should suitably to improve supply voltage to linear resolution.It is 1 milliampere that digital milliammeter is adjusted into least count.During to line; If one 10 core cable is after all inserting well arbitrarily on the terminal box; At the cable opposite side, get arbitrarily on the common port that a core is connected host box, appoint again and get a core and be connected on the line end; Can know that by figure this moment, the reading of milliammeter was I=30V/ (zero-regulator resistor+to the pairing resistance value of the heart yearn that line end connected).Any heart yearn that is connected on this terminal box all can be used as concentric line by on the diode guiding common bus; Therefore this mode of connection biggest advantage has been abandoned the earth as concentric line exactly in the time of to line, has avoided in a lot of occasions problem difficult to line of bringing of ground wire disappearance or bad connection altogether on business.
It is thus clear that, suitably adjust the resistance of each Rw of terminal box, make when jack 1 pairing resistance is connected; The milliammeter reading just in time is 1 milliampere, and when jack 2 pairing resistance were connected, the reading of milliammeter just in time was 2 milliamperes; By that analogy, adjust the resistance of 10 Rw after, when the heart yearn that connects this jack when line end is linked to each other; Reading is the numbering on the terminal box, has so just realized the purpose to line.Zero-regulator resistor 23 on the host box is suitably adjusted when voltage reduces as longer service time when power-supply battery, guarantees the accuracy to line.
The above is merely the preferred implementation of the utility model, but the utility model protection domain is not limited thereto.Any those skilled in the art all can carry out suitable change or variation to it in the disclosed technical scope of the utility model, and this change or variation all should be encompassed within the protection domain of the utility model.
