Abstract
The utility model relates to a miniature circuit detecting instrument, which is used for a relative innovative design, or is used for overhauling other miniature circuits. The instrument adopts two groups of indicating lamps, one group of the indicating lamps is electrified, and the other is not electrified; according to the actual demand of detecting a circuit, a converting regulator is used for selecting the indication of detection. Because of the special condition of the miniature circuit, the instrument is additionally provided with a potential regulator which is formed by adopting five stage resistors different from each other and are selectively adjusted according to the actual condition of a circuit to be detected. In addition, the adoption of an ultrafine probe is for the safety of preventing a short circuit when a dense corner is detected.
Description
Affiliated technical field: the utility model relates to the microcircuit detector of the circuit of a kind of maintenance or innovation.
Background technology: at present, known great majority are the instruments that adopt multimeter and so on, but do not see with this and design.
Summary of the invention: for above-mentioned truth, the utility model provides a kind of microcircuit detector, and its feature is: adopt two groups of pilot lamp, one group is charged, another group is not charged, by conversion regulator, selects on merits to regulate and uses, next is to use fine probe, coming testing circuit, in microcircuit, is intensive structure, seeking various truths, the safety of anti-short circuit.
The utility model solves its technical matters, and the technical scheme that is adopted is: with two groups of pilot lamp, one group is charged, and another group is not charged, presses actual needs, selects detection circuit with conversion regulator.Because necessity of microcircuit, the spy sets up potential regulator, and the resistance that adopts Pyatyi to have nothing in common with each other is by required on the detected circuit and the usefulness of adjusting.
The effect that the utility model is useful is: (one) is simple in structure, volume is little.(2) with conversion regulator, select charged and uncharged indicating mode, press actual needs clear and definite truth on pilot lamp.(3) probe is fine, can detect each intensive corner, is not afraid of the accurate use of short circuit.
Description of drawings: the utility model is further specified below in conjunction with drawings and Examples.
1. conversion regulators, 2. potential regulators 3. have electrode contacts 4. electrodeless contacts 5. no electrical resistivity surveys to survey lamp 6. charged detection lamp 7.10 Ω resistance 8.100 Ω resistance 9.1k resistance 10.5k resistance 11.10k resistance 12. positive electrodes 13. negative electrodes 14. positive probe 15. negative probes among the figure.
Embodiment: embodiment is: in the accompanying drawings, by conversion regulator (1), potential regulator (2), electrode contacts (3) is arranged, electrodeless contact (4), no electrical resistivity survey is surveyed lamp (5), charged detection lamp (6), 10 Ω resistance (7), 100 Ω resistance (8), 1k resistance (9), 5k resistance (10), 10k resistance (11), positive electrode (12), negative electrode (13), positive probe (14), negative probe (15) and the circuit composition that is linked in sequence, be characterized in: conversion regulator (1), be used for charged and uncharged two kinds of tests, and potential regulator (2), usefulness for the safety of microcircuit.Not surveying lamp (5) but there is electrical resistivity survey, is the circuit that is used to have electricity, the usefulness of being surveyed.So-called charged detection lamp (6) is to be used to not have the usefulness of surveying on the circuit of electricity.About potential regulator (2), the resistance that wherein has Pyatyi to have nothing in common with each other should be by required on the detected circuit and the usefulness of adjusting.And the needle point of probe is superfine, i.e. (14) and (15) are used for intensive circuit corner, seeks the safety of the anti-short circuit of various truths and uses.
