The other end of the reset frame is connected with the trip sheet. The lower end of the trip piece is provided with an inverted hook which is fixedly connected with the movable frame, the inverted hook is matched with the movable contact piece, the movable contact piece and the fixed contact piece are respectively provided with mutually matched contacts, the iron guide spring is arranged outside the iron guide, and the movable frame and the fixed contact piece are integrally fixed on the movable frame. Has the advantages of simple structure, stable performance and small volume, and is an ideal safety article for household appliances.
Description
The utility model relates to a kind of leakage protecting plug.
The leakage protecting plug of known use comprises housing, pin, wiring board, zero-sequence transformer and trip gear, when leakage current occurring, and the action of wiring board control trip gear, the corresponding action contact disconnects, and reaches the purpose of protection load.The complex structure of trip gear in this leakage protecting plug, volume is big, and the reliability of action is also poor.
The purpose of this utility model is to overcome the above-mentioned deficiency of common leakage protecting plug and leakage protecting plug that a kind of simple in structure, highly sensitive, dependable performance is provided.
The utility model comprises housing, pin, wiring board, zero-sequence transformer and trip gear, zero-sequence transformer is fixing to be connected in the circuit board and with pin, trip gear is by the frame that resets, back-moving spring, reset button, armature, the dropout sheet, armature (iron), the armature (iron) spring, the armature (iron) coil, adjustable shelf, movable contact spring, fixed touching plate and contact constitute, back-moving spring is arranged in the frame that resets, one end and armature offset, reset button is arranged on outside the housing and with an end of the frame that resets and is connected, the other end of frame of resetting be provided with overhead kick and with the adjustable shelf Joint, overhead kick matches with movable contact spring, respectively be provided with the contact that cooperatively interacts on movable contact spring and the fixed touching plate, the armature (iron) spring is installed in outside the armature (iron), both as an overall fixed on adjustable shelf, when electric leakage takes place or gets an electric shock in circuit, zero-sequence transformer produces voltage, and, make the armature (iron) coil produce magnetic field through the electronic amplification circuit amplification; The action of attraction armature (iron).And the elastic force that overcomes the armature (iron) spring drives adjustable shelf and moves, and promotes the dropout sheet and threads off, and the contact on movable contact spring and the fixed touching plate is separated, thereby cuts off the electricity supply, and prevents electrical leakage, and the contact accident takes place.Energized once more after the subduction fault is pressed reset button, and the dropout sheet is resetted.
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Fig. 1 is this practical structural representation.
Fig. 2 is the A-A cutaway view of Fig. 1.
As shown in the figure, the utility model comprises housing (1), pin (2), wiring board (3), zero-sequence transformer (4) and trip gear, zero-sequence transformer (4) is fixed on the wiring board (3), and be connected with pin (2), trip gear is by the frame that resets (5), back-moving spring (6), reset button (7), armature (8).Dropout sheet (9), armature (iron) (10), armature (iron) spring (11), armature (iron) coil (12), adjustable shelf (13), movable contact spring (14), fixed touching plate (15) and contact (16) constitute, back-moving spring (6) is arranged in the frame that resets (5), one end and armature (8) offset, and the knob that resets (7) is arranged on outside the housing (1), and are connected with an end of the frame that resets (5), the other end of frame of resetting is connected with dropout sheet (9), the lower end of dropout sheet (9) be provided with overhead kick (17) and with adjustable shelf (13) Joint.Overhead kick (17) matches with movable contact spring, respectively is provided with the contact (16) that cooperatively interacts on movable contact spring (14) and the fixed touching plate (15), and armature (iron) spring (12) is installed in outside the armature (iron) (10), both as an overall fixed on adjustable shelf (13).During use, press reset button (7), overhead kick (17) on the dropout sheet (9) that is connected with the frame that resets (5) is colluded toward movable contact spring (14), movable contact spring (14) and fixed touching plate (15) upper contact (16) are contacted, circuit is connected, in when, electric leakage taking place or getting an electric shock when, zero-sequence transformer (4) produces voltage, and go up electronic amplification circuit through wiring board (3) and amplify, make armature (iron) coil (12) produce magnetic field, attract armature (iron) (10) action, the elastic force that armature (iron) (10) overcomes armature (iron) spring (11) drives adjustable shelf (13) motion, promote dropout sheet (9) and move, overhead kick (17) and movable contact spring (14) are separated, two contacts (16) disconnect, thereby cut off the electricity supply, prevent the generation of accident, when reusing, only need press reset button (7) again and dropout sheet (9) be resetted get final product.
The utility model is by above-mentioned concrete structure, and the complexity of having simplified trip gear connects Connect relation, have simple in structurely, volume is little, and adjustment link is few, and is easy to use, spirit The sensitivity height, reliability is strong, steady performance, simultaneously, because shell has adopted Fire-retardant plastics manufacturing has effectively prevented the generation of disaster accident, is a kind of desirable leakage The electric protection plug.
