Abstract
The utility model discloses an electromagnetic circuit breaker, which comprises a coil (1), an armature (2) and a latch fastener (3). The armature (2) adopts an L-shape, the corner of the L-shape is hinged with a bracket (5) through a hinge pin (4), the two sides of the L-shape are respectively a suction arm (6) and a shifting arm (7), and the suction arm (6) is positioned at one end of the pole terminal (8) of the coil (1); and a bend (9) is arranged on the shifting arm (7), and the end of the shifting arm (7) is positioned on one side of the middle part of a latch fastener shaft (10). The electromagnetic circuit breaker has prolonged service life, improved connection stability, and increased current capacity. Or, under the same current capacity, the electromagnetic circuit breaker has reduced volume, improved product quality and reduced production cost.
Description
Technical field
The utility model relates to a kind of electro-magnetic circuit breaker, belongs to small electrical air cock technical field.
Background technology
The driving lever of existing electro-magnetic circuit breaker upper armature is a straight-bar, and driving lever is positioned at snap close one side, and the end of driving lever is positioned at a side of snap close axle one end.When coil electricity, the pole shoe of coil is inhaled moving armature, makes the driving lever of armature stir snap close, and the effect that latches in spring drives the moving contact tripping operation down, moving contact is disconnected with fixed contact be connected, and reaches the purpose of cutting off circuit.
Because existing driving lever is straight-bar, the end of driving lever is stirred snap close from the side, so must reserve the position of driving lever, makes and the hinged place excesssive gap of moving contact and connecting plate causes the connection stability decreases; The width that also can't strengthen moving contact allows electric current to improve; Also be difficult to further dwindle again the thickness of electro-magnetic circuit breaker.Because driving lever is stirred an end of snap close, make bearing pin produce moment of torsion, balance is bad, influences the electro-magnetic circuit breaker working life.
The utility model content
The purpose of this utility model is, a kind of electro-magnetic circuit breaker is provided.With working life and the connection stability that improves electro-magnetic circuit breaker.The utility model is in further reduced volume or keeping can improving current capacity under the situation of existing constancy of volume under the prerequisite of holding current capacity.Improve the quality of products, reduce production costs.
The technical solution of the utility model: a kind of electro-magnetic circuit breaker, comprise coil, armature and snap close, armature is that L shaped, L shaped corner's via pins and support is hinged, and two L shaped limits are respectively adhesive arm and moving arm, and the adhesive arm is positioned at pole shoe one end of coil; Moving arm is provided with bending, and the end of moving arm is positioned at middle part one side of snap close axle.
In the aforesaid electro-magnetic circuit breaker, the snap close axle is provided with snap close.
Compared with prior art, electro-magnetic circuit breaker of the present utility model is that two bendings are set on the driving lever of armature, make the end of driving lever be positioned at middle part one side of snap close axle, driving lever is stirred the middle part of snap close axle when armature movement, can not produce moment of torsion, stress balance, the useful life that can improve electro-magnetic circuit breaker.Because the end of driving lever is positioned at middle part one side of snap close axle, need not stir snap close in addition, reserve bigger gap so not be used in the hinged place of moving contact and connecting plate yet, so can improve the stability of connection at side; Also can widen moving contact, make on the moving contact and can pass through bigger electric current, improve the current capacity of electro-magnetic circuit breaker.Or under the constant situation of holding current capacity, dwindle the volume of electro-magnetic circuit breaker.Improve the quality of products, reduce production costs.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation after the tripping operation.
Being labeled as in the accompanying drawing: 1-coil, 2-armature, 3-snap close, 4-pin, 5-support, 6-adhesive arm, 7-moving arm, 8-pole shoe, 9-bending, 10-snap close axle, 11-moving contact.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but not as to any restriction of the present utility model.
Embodiment.The utility model as shown in Figure 1.A kind of electro-magnetic circuit breaker comprises coil 1, armature 2 and snap close 3, and armature 2 is that L shaped, L shaped corner's via pins 4 is hinged with support 5, and two L shaped limits are respectively adhesive arm 6 and moving arm 7, and adhesive arm 6 is positioned at pole shoe 8 one ends of coil 1; It is characterized in that: moving arm 7 is provided with bending 9, and the end of moving arm 7 is positioned at middle part one side of snap close axle 10; Snap close axle 10 is provided with snap close 3.
Operation principle of the present utility model
The utility model is that two bendings are set on the moving arm on the armature of electro-magnetic circuit breaker 7, makes the end of moving arm 7 withstand on middle part one side of snap close axle 10.Though have only this point to change, make can not produce moment of torsion in armature 2 is stirred snap close axle 10 when action middle part that stress balance can prolong useful life of electro-magnetic circuit breaker.The width that also can widen moving contact 11 improves the electric current handling capacity, can also reduce the hinged gap of moving contact and connecting plate, prevents moving contact left and right sides play, improves the stability that connects; Dwindle the volume of electro-magnetic circuit breaker under can also the holding current capacity constant situation.Improve the quality of products, reduce production costs.
Claims (2)
1. electro-magnetic circuit breaker, comprise coil (1) and armature (2), armature (2) is that L shaped, L shaped corner's via pins (4) is hinged with support (5), two L shaped limits are respectively adhesive arm (6) and moving arm (7), and adhesive arm (6) is positioned at pole shoe (8) one ends of coil (1); It is characterized in that: moving arm (7) is provided with bending (9), and the end of moving arm (7) is positioned at middle part one side of snap close axle (10).
2. electro-magnetic circuit breaker according to claim 1 is characterized in that: snap close axle (10) is provided with snap close (3).
