Abstract
The utility model discloses a circuit connecting or breaking test pen, belonging to the test tool of electric equipment. The circuit connecting or breaking test pen is composed of an external connection conducting wire, a test contact head, a shell body which is made of a transparent insulation material, and an internal circuit. The faucet of the external connection conducting wire shell body is arranged on the shell body. A direct current power supply and a light emitting diode are connected in series to form the internal circuit. The utility model has the advantages of simple structure, convenient portability, low cost, high safety and high reliability. The circuit connecting or breaking test pen can carry out testing for a transformer, a motor, a contact point, a switch circuit, etc. The circuit connecting or breaking test pen provides an ideal test tool for a working occasion whose working environment is bad.
Description
The utility model is a kind of connecting and disconnecting of the circuit test pen, belongs to the testing tool of consumer, forms by external wire, test contact with by housing and internal circuit that the transparent insulating material is made.
At present; multimeter is used in maintenance to consumer break-make fault usually; but the more abominable occasion of many working environments (as under the coal mine, rig floor); because the detecting instrument of multimeter one class; volume is big, weight is big, be difficult for carrying, so; the workman adopts these informal means to overhaul breaking down often, so usually can cause adverse consequences (causing gas explosion in underground coal mines as producing spark).
A kind of volume is little, in light weight, easy to carry, safe in utilization, the reliable detection instrument in order to provide for the purpose of this utility model.
The utility model is to adopt following measure to realize: this connecting and disconnecting of the circuit test pen, form by external wire, test contact with by housing and internal circuit that the transparent insulating material is made, wherein on housing, have the external wire socket, this socket is positioned at the rearward end of housing, internal circuit is formed by direct supply and light emitting diode series connection, and an end of this series circuit is linked in test contact, and the other end links in the external wire socket.During use one end of external wire is inserted the external wire socket, the other end of external wire and test contact are contacted with the two ends of institute slowdown monitoring circuit, when circuit turn-on, the direct supply formation loop in the break-make pen, lumination of light emitting diode; When open circuit fault appearred in circuit, light emitting diode was not luminous, thereby reached the purpose of detection.
Connecting and disconnecting of the circuit test pen described in the utility model has simple in structure, easy to carry, with low cost, advantage such as safe in utilization, reliable can detect transformer, motor, contact, on-off circuit etc., for the workplace of work under bad environment provides a kind of easy service kit.
Accompanying drawing 1 has provided the utility model structural representation.
Specifically describe as follows to the utility model in conjunction with the accompanying drawings: this connecting and disconnecting of the circuit test pen is formed by made the housing 1, external wire 2 and the internal circuit that have test contact 3 on it by the transparent insulating material, rearward end at housing 1 is provided with external wire socket 4, test contact is fixed on the leading section of housing 1, its internal circuit is in series by light emitting diode 5 and battery 6, one end and the test contact 3 of this series circuit link, the other end and external wire socket 4 link, and wherein battery 6 is 4.5 volts.During use, one end of external wire 2 is inserted in the external wire socket 4, with the other end of external wire and touch examination contact 3 and contact with the two ends of the circuit of institute measurement equipment, when the circuit normally of institute's measurement equipment, battery 6 constitutes loops, and light emitting diode 5 is luminous, when the circuit breaker of institute's measurement equipment, light emitting diode is not luminous, thereby reaches the purpose of detection.
Claims (2)
1, a kind of connecting and disconnecting of the circuit test pen, form by external wire, test contact with by housing and internal circuit that the transparent insulating material is made, it is characterized by: have the external wire socket on the housing, its internal circuit is formed by direct supply and light emitting diode series connection, one end and the test contact of this series circuit link, and the other end and external wire socket link.
