Abstract
The utility model relates to a detector for an open circuit of a power supply line. The detector comprises three detection loops, wherein each detection loop consists of a power supply, a bulb, a switch and two pins; one of pins is connected with the switch in series, the switch is connected with the power supply in series, the power supply is connected with the bulb in series, and the bulb is connected with the other pin in series; the three detection loops can be connected in series to detect; and each power supply is a direct current power supply consisting of two batteries. The detector for the open circuit of the power supply line does not break an insulating layer; the three detection loops can detect a zero line, a live line and a ground line synchronously so as to detect which line is in the open circuit; and the three detection loops can be also connected in series to detect the same line to judge which section of the line is in the open-circuit. The detector for the open circuit of the power supply line is convenient, quick and practical, and is simple in structure and low in cost.
Description
Technical field:
The utility model relates to a kind of power lead detecting device that opens circuit.
Background technology:
All be coated with a layer insulating on the live wire of power lead, zero line and the ground wire; Power lead is sometimes because folding, bending, collision etc. are former thereby fracture; Because being coated with the insulation course people is difficult to conclude to be that which root line has broken, general bad power lead has been wasted with regard to throwing away.Conventional detection is destroyed insulation course again, and is very inconvenient, and can influence normolineal use.
The utility model content:
The purpose of the utility model is the weak point to prior art, and a kind of power lead detecting device that opens circuit is provided, and does not destroy insulation course, easy to detect fast.The utility model is simple in structure, and cost is low, practicality.
The technological solution of the utility model is following:
The power lead detecting device that opens circuit comprises and detects the loop that described detection loop has three groups; Said detection loop is made up of power supply, bulb, switch and two contact pins, and wherein a contact pin is connected in series switch, switch serial connection power supply, power series bulb, another contact pin of bulb serial connection; Described three groups of detection loops can be connected in series to be detected.
In the technique scheme, said power supply is the direct supply that two batteries are formed.
The beneficial effect of the utility model is:
The utility model has three groups to detect the loop, and three groups of detection loops can be detected zero line, live wire and ground wire separately simultaneously, and detecting which root line is to open circuit, and three groups of detection loops can be serially connected and detect same single line simultaneously, and judging which section is to be in off state.The utility model is fast convenient, and simple in structure, cost is low, and practicality does not destroy insulation course during detection, easy to detect, does not influence normolineal use.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the detection loop structure synoptic diagram of the utility model;
Fig. 2 is three groups of structural representations that detect the loop series connection of the utility model.
Embodiment:
The following stated is merely the preferred embodiment of the utility model, is not that scope to the utility model limits.
Embodiment sees and attaches Fig. 1 and 2, and the power lead detecting device that opens circuit comprises and detects the loop, and described detection loop has three groups; Said detection loop is made up of power supply 1, bulb 2, switch 3 and two contact pins 4,5, and wherein a contact pin is connected in series switch, switch serial connection power supply, power series bulb, another contact pin of bulb serial connection; Described three groups of detection loops can be connected in series to be detected.
Said power supply is the direct supply that two batteries are formed.
During use, three groups are detected loops and can detect zero line, live wire and ground wire simultaneously separately, and detecting which root line is to open circuit, as long as two contact pins are inserted insulation courses and on lead contacted, the bright explanation of bulb was not opened circuit, and has opened circuit otherwise prove.Three groups of detection loops can be serially connected and detect same single line simultaneously, and six contact pins are inserted on the lead simultaneously, and detecting which section quickly and easily is to be in off state; Do not destroy insulation course during detection; Easy to detect, do not influence normolineal use, the utility model is simple in structure; Cost is low, practicality.
