Description
Technical field
The present invention relates to a kind of connector, relate in particular to a kind of Experiment of Electrical Engineering ammeter access device of connecting.
Background technology
In colleges and universities' Experiment of Electrical Engineering, often to measure the electric current of multiple branch roads in a circuit.Therefore need student's access ammeter of repeatedly connecting.For shortening experimental period, avoid student, in wiring process, Danger Electric shock risk occurs, on the education experiment circuit of producing in some instruments used for education producers at present, two core coaxial sockets can be installed, coordinate as the ammeter access device of connecting with two core coaxial plugs.During ammeter series connection access device can make to test, current measurement is safer, convenient, fast.But two core coaxial sockets are mainly used in stereo set, be generally mechanical endurance 5000 times, long-time frequent plug in Experiment of Electrical Engineering, socket inner shrapnel generation plastic deformation, contact point cannot contact, and causes this socket place branch road open circuit in experimental circuit.And when plug insertion socket, in socket, part shell fragment contact point discord plug rubs, and therefore easily forms oxide layer, causes contact resistance increase.In the time that above-mentioned fault occurs, whole experimental circuit changes.Student's measurement data will be made mistakes in this case, and whole experiment sometimes even all will be done one time again again, has a strong impact on teaching efficiency.In addition, use the reference direction that two core coaxial sockets cannot the tested electric current of intuitive judgment.Therefore need the device of mechanical endurance and better reliability to substitute two core coaxial sockets.
Summary of the invention
The technical solution adopted for the present invention to solve the technical problems is: ammeter series connection access device is made up of plug and socket two parts.Socket has a conductive path, and this path is turned round by two torsionsprings and spring metal axle sleeve and the roller on arm, installed and formed, and above-mentioned path is connected on the tested branch road of education experiment circuit.Plug also has a conductive path, and this path is made up of side of the positive electrode sheet metal, negative side sheet metal, wire and ammeter.In the time of plug insertion socket, plug side of the positive electrode and negative side sheet metal respectively with homonymy torsionspring on roller contact squeeze, torsionspring is deformed, conductive path in socket disconnects, in conductive path series connection access socket conductive path in plug, reach the object of ammeter series connection access experimental circuit simultaneously.Select to replace shell fragment with torsionspring and can increase elastic range, the prolonged mechanical life-span, and when plug insertion socket, in socket, roller and plug both positive and negative polarity both sides sheet metal rub, stop oxide layer formation, the handle of the handle of plug side of the positive electrode and wire and negative side and wire use different colours, the reference direction of selecting when energy intuitive judgment is measured.
The invention has the beneficial effects as follows, ammeter series connection access device can safe ready ammeter is sealed in tested branch road, have longer mechanical endurance, the reference direction of selecting when electric current is measured in energy intuitive judgment, has great role to improving experiment teaching effect.
