Abstract
The utility model discloses a miniature circuit breaker comprising a shell which is internally provided with an operating mechanism, a moving contact, a static contact and an arc extinguishing chamber and is also provided with a through hole, wherein the moving contact is hinged with the shell through a moving contact support; and the moving contact support comprises a semicircle cambered surface which faces the through hole 6 and is provided with two colors. The miniature circuit breaker is easy to be distinguished in the disconnection state or the connection state, so that the misoperation can be avoided and the convenience for a user can be provided.
Description
Technical field
The utility model relates to a kind of miniature circuit breaker, and particularly a kind of circuit breaker of recognizing is in the miniature circuit breaker of disconnection or closure state.
Background technology
At present; miniature circuit breaker is generally adopted in low-pressure field; its structure mainly comprises operating mechanism, moving contact and fixed contact, arc control device, overload protection arrangement and binding post composition; wherein operating mechanism mainly comprises snap close, tripping, moving contact frame, " U " connecting rod and handle; can realize the disconnection and the closure of dynamic/static contact by operating grip; also can control the disconnection and the closure of dynamic/static contact by the cooperation of snap close and tripping; therefore operating personnel are difficult to judge what state this miniature circuit breaker is in when operation, therefore easily produce misoperation.Therefore, it can be in closure state or off-state by this circuit breaker of intuitive judgment to need to create a kind of circuit breaker.
The utility model content
Problem to be solved in the utility model provides a kind of circuit breaker of recognizing and is in the miniature circuit breaker of disconnection or closure state, overcomes above-mentioned technical problem of the prior art.
The utility model is solved by the following technical solutions:
A kind of miniature circuit breaker of the present utility model, comprise housing, be provided with operating mechanism, moving contact, fixed contact and arc control device in the housing, housing is provided with through hole, described moving contact is hinged by moving contact frame and described housing, described moving contact frame comprises a semicircle cambered surface towards the through hole direction, and this semicircle cambered surface is provided with two kinds of different colors.
Arc control device described in the utility model are located at described housing bottom, and described fixed contact is located at the air inlet of arc control device, and described moving contact is located at the opposite of fixed contact.
The utility model also comprises the binding post that is located in the described housing, and described housing is provided with binding post and inserts the hole, also is provided with the protection baffle plate in the described housing and is located between described binding post and the described binding post access hole.
By above technical scheme, miniature circuit breaker of the present utility model is provided with different colours by the moving contact frame top, does not see different colors simultaneously at circuit-breaker status from through hole, judges that according to this circuit breaker is to be in to disconnect or closure state, bring convenience to use, avoid misoperation.
Description of drawings
Fig. 1 is the structure chart of the utility model miniature circuit breaker.
Embodiment
As shown in Figure 1, miniature circuit breaker of the present utility model comprises housing 1, be provided with operating mechanism in the housing, moving contact 3, fixed contact 4, arc control device 5, bimetal leaf 10 and overload coil 15, operating mechanism comprises handle 2, snap close 11, tripping 13 and moving contact frame 7, handle 2 links to each other with moving contact frame 7 by " U " type connecting rod, moving contact 3 is installed on the moving contact frame 7, arc control device 5 are located at housing bottom, fixed contact 4 is positioned at the entrance side of arc control device 5 and is fixed on the yoke 14, moving contact 3 is corresponding with fixed contact 4, snap close 11 and tripping 13 are all hinged with housing, and snap close 11 can block mutually with tripping 13, is provided with iron core in the overload coil 15, yoke 14 is electrically connected with overload coil, iron core one end is electrically connected with snap close 11, and the other end of iron core is corresponding with moving contact frame, is arranged on moving contact fixed contact motion relatively on the yoke to realize fixed contact.Also be provided with through hole 6 on the housing 1, moving contact frame 7 comprises a semicircle cambered surface towards through hole 6 directions, this semicircle cambered surface is provided with two kinds of different colors, judges by the demonstration of different colours what state moving contact and fixed contact are in, and the handled easily personnel use and avoid misoperation.
The utility model also comprises the binding post 16,17 that is located in the housing 1; moving contact 3 is electrically connected with binding post 16; binding post 17 is electrically connected with bimetal leaf 10; moving contact 3 and fixed contact 4 closed types; binding post 16, moving contact 3, fixed contact 4, yoke 14, overload coil 15, bimetal leaf 10, binding post 17 constitute the loop; if electric current is excessive in this loop; then make overload coil produce bigger magnetic field force; the action of attraction iron core; iron core drives the snap close action; tripping and snap close break away from, and realize overload protection.On the housing 1 of miniature circuit breaker, be provided with binding post and insert hole 8; carry out error connection for fear of pair of wire connection terminals 16,17; and in housing, being provided with protection baffle plate 9, protection baffle plate 9 is plugged in the housing and is located at binding post 16,17 and binding post inserts between the hole 8.
