Abstract
The utility model relates to a cable, in particular to an alarming cable which is woven to a pigtail shape. The utility model mainly solves the technique problem that the current common cable has no alarming function or is easy to be broken. The pigtail-shaped cable is braided by three insulating conductive enameled wires of a core wire (1), a core wire (2) and a core wire (3), and the outer end parts of the core wire (1) and the core wire (2) are communicated with each other. The inner ends of the three core wires of the core wire (1), the core wire (2) and the core wire (3) are connected with an alarming control circuit. The utility model can be used as a wire net for frontiers, ammunition warehouses and prisons, and the cable can give an alarm automatically after being attacked, therefore the utility model has functions of spy prevention, theft protection and fire prevention.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of alarm cable of plait shape.
Technical background
Existing common cable does not have warning function, and is easy to destroyed.
Summary of the invention
The purpose of this utility model is to provide a kind of Plait cable that is formed by three enamelled wire heart yearns braidings that goes to pot and can report to the police.The purpose of this utility model is achieved through the following technical solutions: the plait shape cable that the conductive paint envelope curve heart yearn 1 of three mutually insulateds, heart yearn 2 and heart yearn 3 intersections are formed by weaving, the outer end of heart yearn 1 and heart yearn 2 is communicated with.The inner and the alarm control circuit of three heart yearn heart yearns 1, heart yearn 2 and the heart yearn 3 of described Plait cable join.Described alarm control circuit, its resistance R 1 connects heart yearn 1, heart yearn 2 respectively with the circuit that integrated package of pressure-stabilizing circuit BG1 forms, the output alarm relay J1 of integrated package of pressure-stabilizing circuit BG1, connect heart yearn 3 by resistance R 2, resistance R 3, alarm relay J2 and triode BG2 built-up circuit, alarm relay J1 and alarm relay J2 meet relay switch J1-1, J2-1 circuit B taking alarm in parallel respectively.Integrated package of pressure-stabilizing circuit BG1 is the integrated diode circuit of voltage regulation TL431 integrated package of voltage-controlled type.The utility model can be used for being used as wire netting around the frontier front, munition warehouse, prison to be used, but it than wire netting can automatic warning function after damaging more, so the destruction of guarding against enemy agents; Compare have guard against enemy agents, antitheft and fire-proof function, so claim Plait cable.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a cross sectional representation of the present utility model;
Fig. 3 is a warning circuit schematic diagram of the present utility model.
Embodiment
By Fig. 1 to Fig. 3 as can be known, the utility model is by the conductive paint envelope curve heart yearn 1 of three mutually insulateds, the plait shape cable that heart yearn 2 and heart yearn 3 intersections are formed by weaving, the outer end of heart yearn 1 and heart yearn 2 is communicated with, three heart yearn heart yearns 1, the inner and the alarm control circuit of heart yearn 2 and heart yearn 3 join, described alarm control circuit, its resistance R 1 connects heart yearn 1 respectively with the circuit that integrated package of pressure-stabilizing circuit BG1 forms, heart yearn 2, the output alarm relay J1 of the integrated diode circuit of voltage regulation TL431 integrated package BG1 of voltage-controlled type, by resistance R 2, resistance R 3, alarm relay J2 and triode BG2 built-up circuit connect heart yearn 3, and alarm relay J1 and alarm relay J2 meet relay switch J1-1 in parallel respectively, J2-1 circuit B taking alarm.Integrated package of pressure-stabilizing circuit BG1 is.Described TL431 integrated package is the integrated diode circuit of voltage regulation of voltage-controlled type, and there is the accurate reference voltage of a 2.5V voltage its inside, and its reference edge is very high to the distinguishing ability of input voltage.When it is compared with the input voltage of reference edge, as long as when the reference voltage of reference edge R surpasses 2.5V or ≌ 2.5V, the conducting of TL431 integrated package.
When cutting off cable, as long as heart yearn 1, heart yearn 2 lines cut off, as shown in Figure 3, resistance R 1 connects supply reference voltage for TL431 integrated package BG1, TL431 integrated package BG1 conducting, then alarm relay J1 make relay switch J1-1 conducting then warning circuit B report to the police.
If at heart yearn 1, heart yearn 2, heart yearn 3 line two ends are connected the line of correspondence one by one with another root lead, just heart yearn 1-heart yearn 1 is connected with a lead, heart yearn 2-heart yearn 2 is connected or heart yearn 3-heart yearn 3 is connected, cut off cable then, but this accomplishes very much, because heart yearn 1, heart yearn 2,3 three enamelled wires intersections of heart yearn are formed by weaving the plait shape, be difficult to tell heart yearn 1, heart yearn 2, the correspondence position of heart yearn 3, as long as mistake is with heart yearn 1, heart yearn 2 lines connect to heart yearn 3 lines, triode BG2 as shown in Figure 3, resistance R 2, the circuit that resistance R 3 is formed is connected, and alarm relay J2 makes then warning circuit B warning of relay switch J2-1 conducting.Because heart yearn 1, heart yearn 2, heart yearn 3 these three enamelled wires are that interlacing forms the plait shape, wanting to remove insulating varnish is difficult to, in case and heart yearn 1, heart yearn 2 lines and heart yearn 3 lines join and bump, then the circuit of being made up of triode BG2, resistance R 2, resistance R 3 is connected, and alarm relay J2 makes then warning circuit B warning of relay switch J2-1 conducting.
