Description
Technical field
The utility model belongs to electromechanical engineering technical field, particularly relate to a kind of can the wire breakage detection device for cables of parallel detection.
Background technology
In electromechanics construction, before cable uses, often need to measure cable break-make, current, do not have standardized technical matters to the break-make of cable, people have devised multiple detection scheme, but be the technique detected single cable, efficiency is lower.
Summary of the invention
The purpose of this utility model be to provide a kind of can the wire breakage detection device for cables of parallel detection, when using above-mentioned prior art to solve, existing the problems referred to above.
For realizing the purpose of this utility model, the utility model provide a kind of can the wire breakage detection device for cables of parallel detection, described device comprises, self-excited oscillator, decade counter/pulsqe distributor and LED indicating circuit composition, described self-excited oscillator circuit comprises the first transistor, transistor seconds and the first resistance, second resistance, 3rd resistance, first capacitor, described decade counter/pulsqe distributor is integrated circuit (IC) chip, described LED indicating circuit comprises multiple parallel detection and connects branch road, arbitrary described detection connects branch road and includes a resistor and light emitting diode.
The utility model, compared with prior art, when in use, by circuit kit structure, can connect Stranded cable, can carry out break-make detection simultaneously, be convenient to industrially promotion and application to Stranded cable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1-first resistance, 2-first electric capacity, 3-transistor seconds, 4-the 3rd resistance, 5-the first transistor, 6-second resistance, 7-decade counter/pulsqe distributor, 8-switch, 9-LED indicating circuit resistance, 10-light emitting diode.
Embodiment
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly understand, below in conjunction with embodiment, the utility model is further elaborated.Should be understood to specific embodiment described herein only in order to explain the utility model, be not limited to protection domain of the present utility model.
As shown in Figure 1, the utility model provide a kind of can the wire breakage detection device for cables of parallel detection, described device comprises, self-excited oscillator, decade counter/pulsqe distributor and LED indicating circuit composition, described self-excited oscillator circuit comprises the first transistor, transistor seconds and the first resistance, second resistance, 3rd resistance, first capacitor, described decade counter/pulsqe distributor is integrated circuit (IC) chip, described LED indicating circuit comprises multiple parallel detection and connects branch road, arbitrary described detection connects branch road and includes a resistor and light emitting diode.
In a preferred embodiment, described device can be arranged outer containment vessel, described outer containment vessel is that insulating material is made, in tetragonal body structure and described detection connect branch road extend outside described outer containment vessel.Such structure is easy to carry and improves processing safety.
During detection, can by a certain end ground connection of tested cable, the stranded conductor in the other end connects with multiple output terminals of integrated circuit (IC) chip respectively.The clock pulse signal that self-excited oscillator produces is from the CP end input of integrated circuit (IC) chip.This clock pulse signal, after processing of circuit in integrated circuit (IC) chip, exports high level successively from its multiple output terminal.When tested cable is intact, light emitting diode does not all work; If in cable during certain strand of wire break, coupled light emitting diode will be lighted.
Wherein, in the utility model, resistance used all can select 1/4W carbon film resistor, and the first electric capacity selects monolithic capacitor or dacron terylene condenser.Light emitting diode all can select the red high brightness LED of ￠ 3mm.Transistor seconds selects S9012 silicon PNP transistor; The first transistor selects S9013 silicon NPN transistor.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
