The auxiliary contact and the switch handle on the miniature circuit breaker can act synchronously, so that the state of the miniature circuit breaker can be provided for a user in time by multiple kinds of external control equipment such as a signal lamp, a buzzer, a controller and the like which are connected with the miniature circuit breaker, the user can quickly know the state of the miniature circuit breaker even through the user is far away from the miniature circuit breaker, and faults can be removed in time once the faults occur. Therefore, the auxiliary contact of the miniature circuit breaker has high safety.
Description
Technical field
The invention belongs to technical field of electrical equipment, particularly relate to a kind of auxiliary contact of miniature circuit breaker.
Background technology
Miniature circuit breaker; Claim miniature circuit breaker again; Be the electrical equipment of terminal protection the most widely that uses in the power distribution equipment of a kind of architectural electricity terminal; Be used for circuit and power consumption equipment are carried out distribution, control and protection, mainly divide assembly system, arc quenching system and operating grip to form by housing, operating mechanism, tripping system, contact, wherein operating grip is positioned at the end face of housing.But there is following point in the miniature circuit breaker of this prior art: present this miniature circuit breaker uses separately usually, and does not have effective protective equipment and deixis on it; If therefore its position of user distance is far away; In case miniature circuit breaker breaks down, then can't learn its state rapidly, therefore also just can not in time fix a breakdown; So might cause serious consequence, promptly exist potential safety hazard.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of auxiliary contact that can improve the miniature circuit breaker of miniature circuit breaker safety in utilization.
In order to achieve the above object, the auxiliary contact of miniature circuit breaker provided by the invention comprises shell, auxiliary contact handle, a plurality of grab and two microswitches; Wherein shell is the flat case shape that a side is formed with opening; The middle part of auxiliary contact handle is hinged on the upper end, side of shell, and the top that is positioned at housing exterior on it is formed with a gangbar to the opening direction of shell is outstanding, and the bottom is outstanding to be formed with a driving lever; A plurality of grabs are arranged on both sides of the edge, shell aperture place, are used for the opening of shell is fixed on the side of miniature circuit breaker; Two microswitches are installed on the side inner surface of shell, and the contact arm on it is positioned at the top, and the driving lever swing time can contact with contact arm, and each microswitch is electrically connected with Different control equipment respectively simultaneously.
Mode with cascade on the described miniature circuit breaker is connected with a plurality of auxiliary contacts.
The position of switch knob lateral aperture is corresponding on the position of described gangbar and the miniature circuit breaker, and the diameter of gangbar is slightly less than the diameter of switch knob lateral aperture.
The side view of described shell is identical with size with the side view of miniature circuit breaker with size, can make the contour structures of miniature circuit breaker change little like this.
Described control appliance comprises signal lamp, fast Chinese percussion instrument or controller.
The auxiliary contact of miniature circuit breaker provided by the invention can with the switch knob synchronization action on the miniature circuit breaker; So just can the state of miniature circuit breaker in time be offered the user through external control deviceses such as coupled signal lamp, fast Chinese percussion instrument or controllers; Even therefore the position of user distance miniature circuit breaker is far away; Also can learn its state rapidly, and in case break down and also can in time get rid of, so fail safe is good.
Description of drawings
Fig. 1 is the auxiliary contact structural representation of miniature circuit breaker provided by the invention.
Fig. 2 is the miniature circuit breaker structural representation that auxiliary contact provided by the invention is installed.
Fig. 3 is for being equipped with the miniature circuit breaker structural representation of auxiliary contact provided by the invention with cascade system.
Embodiment
Be elaborated below in conjunction with accompanying drawing and specific embodiment auxiliary contact to miniature circuit breaker provided by the invention.
Like Fig. 1, shown in Figure 2, the auxiliary contact of miniature circuit breaker provided by the invention comprises shell 1, auxiliary contact handle 2, a plurality of grab 3 and two microswitches 4; Wherein shell 1 is the flat case shape that a side is formed with opening; The middle part of auxiliary contact handle 2 is hinged on the upper end, side of shell 1, is positioned at the outside top of shell 1 on it and is formed with a gangbar 6 to the opening direction of shell 1 is outstanding, and the bottom is outstanding to be formed with a driving lever 7; A plurality of grabs 3 are arranged on shell 1 opening part both sides of the edge, are used for the opening of shell 1 is fixed on the side of miniature circuit breaker 5; Two microswitches 4 are installed on the side inner surface of shell 1, and the contact arm 8 on it is positioned at the top, and can contact with contact arm 8 during driving lever 7 swing, and each microswitch 4 is electrically connected with Different control equipment respectively simultaneously.
Mode with cascade on the described miniature circuit breaker 5 is connected with a plurality of auxiliary contacts.
The position of switch knob 9 lateral aperture is corresponding on the position of described gangbar 6 and the miniature circuit breaker 5, and the diameter of gangbar 6 is slightly less than the diameter of switch knob 9 lateral aperture.
The side view of described shell 1 is identical with size with the side view of miniature circuit breaker 5 with size, can make the contour structures of miniature circuit breaker change little like this.
Described control appliance comprises signal lamp, fast Chinese percussion instrument or controller.
The auxiliary contact of miniature circuit breaker provided by the invention before use; At first the gangbar on it 6 is aimed at the hole and the insertion of switch knob 9 sides on the miniature circuit breaker 5; Be buckled in until the opening on the shell 1 on the side of miniature circuit breaker 5, and the front end face edge that makes a plurality of grabs 3 be stuck in miniature circuit breaker 5 can be accomplished assembling process.
When the switch knob on the miniature circuit breaker 59 is swung downward or upward and is carried out branch, closing operation; Coupled gangbar 6 also will together be swung, and will drive driving lever 7 will move in the opposite direction this moment, thus make the lower end of driving lever 7 be separated from one on the microswitch 4 contact arm 8 and move to another microswitch 4 on contact arm 8 contact; At this moment; The state of previous microswitch 4 will often be become by normally closed (often opening) opens (normally closed), thereby with coupled lighting such as signal lamp of connecing, the state of a back microswitch 4 will become normally closed (often opening) by often opening (normally closed) simultaneously; Thus with coupled connecting of connecing such as fast Chinese percussion instrument, thus the alarm signal of sending.In addition, can adopt cascade system as shown in Figure 3 to connect a plurality of auxiliary contacts, so just can connect other equipment, such as controller etc., to control the different terminal product at a miniature circuit breaker 5.
