Abstract
The mine lamp short-circuit protection relates to a kind of protective device that is used for the mine lamp short circuit.Mainly develop for solving problems such as existing mine lamp short-circuit protection processing, debug difficulties.It comprises housing, coil rack in the housing is a drawer-type structure, the front end of coil rack base is established two fairleads arranged side by side, the yoke plug-in type is installed on the coil rack, the bending of moving contacting plate ears is mounted on the yoke, current coil is on coil rack, a hangers welding of tail end and moving contacting plate, head end is connected with a lead-in wire, quiet contact chip is installed on the coil rack, and the bottom is inserted in another fairlead and is connected with lead-in wire, and potential winding is on coil rack, head end is connected with quiet contact chip bottom circular aperture, tail end hangs over the rear portion of skeleton upper end, and iron core is installed in the coil rack circular hole, with the yoke riveted, moving plate and moving contacting plate rivet together shell nozzle encapsulant involution.Advantage is to be convenient to processing, and debugging is convenient, and shock resistance is good, stable performance.
Description
Technical field:
The utility model relates to a kind of protective device that is used for the mine lamp short circuit.
Background technology:
Existing mine lamp short-circuit protection unreasonable structure, the processing technology complexity, shock resistance is poor, debug difficulties.
Summary of the invention:
The purpose of this utility model provides a kind of rational in infrastructure, is convenient to processing, and debugging is convenient, and antidetonation is good, the mine lamp short-circuit protection of stable performance.
Above-mentioned purpose is achieved in that it comprises housing, coil rack is arranged in the housing, coil rack adopts drawer-type structure, the front end of coil rack base is established two fairleads arranged side by side, the yoke plug-in type is installed on the coil rack, moving contacting plate is mounted on the yoke with the ears wrap direction, current coil is wrapped on the coil rack, hangers welding of tail end and moving contacting plate, head end is connected with lead-in wire in the fairlead, and quiet contact chip employing plug-in type is vertically mounted on the coil rack, the bottom is inserted another fairlead lead-in wire interior and in this fairlead and is connected, potential winding is on coil rack, and head end is connected with quiet contact chip bottom circular aperture, and tail end hangs over the rear portion of skeleton upper end, iron core is installed in the coil rack circular hole, with the yoke riveted, moving plate and moving contacting plate rivet together shell nozzle encapsulant involution.
The utility model has the advantages that: because yoke and coil rack adopt drawer-type structure, contact system adopts Open architecture, so, be convenient to processing, debugging is convenient, and shock resistance is good, stable performance.
Description of drawings:
Fig. 1 is a generalized section of the present utility model;
Fig. 2 is an electrical schematic diagram.
Embodiment: with reference to accompanying drawing 1, it comprises housing 2, coil rack 1 is arranged in the housing, coil rack adopts drawer-type structure, the front end of coil rack base is established two fairleads arranged side by side, yoke 3 plug-in types are installed on the coil rack, moving contacting plate 4 usefulness ears wrap direction are mounted on the yoke, current coil 8 is wrapped on the coil rack, a hangers welding of tail end and moving contacting plate, lead-in wire 10 in head end and the fairlead is connected, quiet contact chip 6 adopts plug-in type to be vertically mounted on the coil rack, and the bottom is inserted another fairlead lead-in wire 10 interior and in this fairlead and is connected, and potential winding 7 is on coil rack, head end is connected with quiet contact chip bottom circular aperture, tail end hangs over the rear portion of skeleton upper end, and iron core 9 is installed in the coil rack circular hole, with the yoke riveted, moving plate 5 rivets together with moving contacting plate, shell nozzle encapsulant 11 involutions.
Mine lamp short-circuit protection operation principle: with reference to accompanying drawing 2, energized K switch electric current through electric current line chart L1, by protector contact J, is got back to power supply negative terminal through filament, at this moment the mine lamp operate as normal by the battery anode again.The current value in loop is the operating current of mine lamp, the operating current that this electric current is set far below device.Therefore, electric current only produces faint magnetic flux by coil L1, the not adhesive of moving plate, and electric current is through the stable circulation of contact J.
When short trouble appears in the mine lamp two ends, the electric current of electric current line chart L1 and contact J of flowing through increases suddenly, the magnetic flux that coil L1 produces also increases suddenly, under bigger flux interaction, iron core is magnetized rapidly, closed magnetic circuit via yoke, moving plate constitute is inhaled to the iron core pole shoe plate, and drives the contact disconnection.After contact J disconnected, short circuit current was through the L2 winding.Because L2 is the voltage winding, so short circuit current is reduced to suddenly＜100mA.But this moment, the magnetic potential of electromagnetic system there was not change, and moving plate and iron core keep attracting state, and contact J keeps the disjunction state.Disconnecting power switch K, after the short trouble eliminating, mine lamp can recover operate as normal automatically.
