Abstract

The utility model discloses a novel experiment used wire safe connector, which is composed of a plug and a socket, wherein the plug is composed of an insulating shell, an outer conductive slide bar, an inner conductive slide bar, an inner spring, an outer spring, a conductive reed and annular magnets; and the socket is composed of an insulating shell, an insulating shell nut, a conductor, a conductor nut and annular magnets. When the plug and the socket are combined and accurately positioned by virtue of the attraction of the annular magnets, the conductor of the socket is connected with the conductive reed of the plug through a combination body of the inner conductive slide bar, the inner spring and the outer conductive slide bar, otherwise, the conductor of the socket is disconnected with the conductive reed of the plug. An end face, which is not contacted with the socket, of the insulating shell of the plug and an end face, which is contacted with the plug, of the insulating shell of the socket are identical in shape, thereby being capable of connecting a plurality of plugs with one socket sequentially in a stacking manner.

A kind of Novel experimental wire breaking piece

Technical field

The utility model relates to a kind of experiment wire breaking piece, especially a kind of safety plug and socket of realizing quick-make and open circuit.

Background technology

Present known experiment wire mainly contains two kinds with connector.The one, knob, consisted of by binding post and U-shaped terminal, binding post consists of with externally threaded metal cylinder (cylinder) with the metal nuts of internal thread by one, metal nuts outer wrapping insulating material, when needing to connect, nut is tightened on the binding post, makes nut press U-shaped binding post and turning circuit, its advantage is that wiring is firm, and shortcoming is connection and disconnects potential safety hazard slow and that existence is got an electric shock; The 2nd, plug-in, consisted of by junction block and pistol type plug, junction block is comprised of metallic cylinder and insulating outer layer, and the pistol type plug is made of plug and the insulated handle with spring leaf, and it is isometric that insulated handle can become tubular to extend to forward with plug along plug direction, when needing to connect, in plug insertion socket, the spring leaf on the plug contacts turning circuit with the socket cylinder, and its shortcoming is: easily cause loose contact, plug length is long, and is stressed flexible even fracture during not along the plug axis direction.

Summary of the invention

The utility model can be realized quick, safe connection, and can realize the stacking connection of plug.

The utility model is achieved in that

A kind of Novel experimental is comprised of plug and socket with the wire breaking piece.Described plug is comprised of insulation crust, outer conduction slide bar, interior conduction slide bar, inner spring, outer spring, conductive reed, annular magnet; Described socket is comprised of insulation crust and nut, electric conductor and nut, annular magnet.

The insulation crust of described socket is the thick cyclinder of the hollow of an end perforate, its end face with the contacted end of plug is identical with plug end face taper angle, the part of the internal conical surface that highly equates, described electric conductor is that a vertical section is the metal cylinder of T-shape, be fixed in the cavity of described insulation crust around its top, stretch out outside the cavity bottom, and make this cavity closed, described annular magnet is wrapped in the heavy wall of socket insulation crust, its circular cross-section is vertical with the insulation crust axis, and its polarity satisfies when the plug lower surface contacts with the socket upper surface and attracts each other.

The insulation crust of described socket and shell nut are used for the fixed socket body, and the electric conductor of described socket and nut are used for the terminal of the fixing wire that is connected with this socket.

Described plug not be connected socket or another plug when connecting, separate with conductive reed under the outside spring action of combination that the outer conduction slide bar of this plug, interior conduction slide bar, inner spring form, interior conduction slide bar and conductive reed and plug lead-out wire are off-state.

When wanting to make described plug to connect described socket, make the plug bottom near the top of this socket, put under the effect of annular magnet the two within it close rapidly, taper angle is identical, the outer conical surface that highly equates and internal conical surface guiding plug correctly are positioned on the socket, when the top of interior conduction slide bar contacts the T-shape metal cylinder of described socket, this cylinder promotes the outer conduction slide bar of described plug, interior conduction slide bar, the combination that inner spring forms overcomes outer spring thrust, axis direction along described insulation crust cavity slides to plug conducting reed direction, to contacting conducting with the conductive reed of described plug, inner spring elastic force makes the electric conductor close contact of interior conduction slide bar and socket.。

Because the upper surface of described plug is identical with the upper surface shape of described socket, therefore can stack gradually a plurality of plugs at same socket, when the stacking plug of wish, make its bottom near the top of last plug, put under the effect of annular magnet the two within it close rapidly, taper angle is identical, the outer conical surface and the internal conical surface that highly equate guide this plug correctly to be positioned on the last plug, when the top of conduction slide bar in this plug contacts conductive reed in the last plug, this reed promotes the outer conduction slide bar of this plug, interior conduction slide bar, the combination that inner spring forms overcomes outer spring thrust, axis direction along this plug insulation crust cavity slides to the conductive reed direction of plug, to contacting with the conductive reed of this plug this plug and last plug are connected, inner spring elastic force makes the conductive reed close contact of interior conduction slide bar and last plug.

When pre-disconnection connects, only need to overcome with external force the attraction of annular magnet, plug and socket or plug and plug are thrown off.

In being switched on or switched off connection procedure, as long as when correctly not locating between plug and socket or plug and plug, combination and conductive reed that the outer spring in the plug all promotes outer conduction slide bar, interior conduction slide bar, inner spring composition disconnect.
