Abstract
The invention discloses an automatic air switch, comprising a shell (1). The middle part of the front end surface of the shell (1) protrudes outwards to form a boss, a safety durable switch knob (2) is arranged on the boss, the shell is provided with threaded holes (3) in the end surfaces at two sides of the boss, wiring ports (5) are arranged on the left and right side surfaces of the shell (1) and are communicated with the threaded holes (3), and a groove (4) is formed in the rear end surface of the shell (1). The automatic air switch has a simple structure, can well protect the switch knob and a user, and is high in safety. The switch knob is additionally provided with a board slot and a cushion, so that noise generated during on and off of a switch is reduced, the safety performance of the switch knob is improved and the service life of the switch knob is prolonged.
Description
Technical field
The present invention relates to switch, specifically refer to the automatic air-break switch for power domain.
Background technology
The dielectric of air switch is air, to close a floodgate with manual (or electronic), keep closing position with snap close, acted on the low tension switch that trips and have arc-control device by tripping mechanism, be widely used in circuit, making connection, disjunction and carrying rated operational current and the fault currents such as short circuit, overload in the following AC and DC device of 500V.When overload, short circuit, lower voltage occuring in the circuit or disappear, the energy automatic shutdown circuit is protected reliably.
Now present automatic air-break switch is when the auto-closing switch, switch switch knob very rapidly bullet closes and closes, the switch switch knob bears great force, and sends the very large sound, like this switch switch knob is caused huge infringement, cause the fracture of switch switch knob, air switch is scrapped, and has greatly shortened the useful life of air switch, and when going to pull air switch with hand, because the great force when closing, may the user's of closing switch hand be damaged.
Summary of the invention
Problem to be solved by this invention provides a kind of automatic air-break switch, is used for solving that automatic air-break switch sound when switch in the past is large, the problem of switch knob easy fracture and poor stability.
Technical scheme provided by the invention is: automatic air-break switch, comprise housing, housing front end face middle part evagination forms boss, boss is provided with the safety durable switch knob, described housing is equipped with screwed hole in the end face of boss both sides, described housing arranged on left and right sides face is equipped with connection jaws, and connection jaws is communicated with screwed hole, and described housing rear end face is provided with groove.This programme is improved to the safety durable switch knob than traditional automatic air-break switch with original common operating switch, has increased switch knob fail safe and useful life, so that the automatic air-break switch use is safer, prolong useful life, practical.
Described safety durable switch knob comprises rotation axis, and the rotation axis periphery is connected with shifting block.Rotation axis and shifting block are as a whole, during use, drive rotation axis by shifting block and rotate, thereby reach on-off action.
Described shifting block upper surface is connected with board slot.The user can pull in use board slot and make things convenient for operating switch, the convenient use.
Described board slot is provided with the friction line in the side of rotation axis.User rub when pulling shifting block line and finger contact increase the frictional force of finger and shifting block, in order to avoid mutually slide when pulling switch knob, have further facilitated the user and have pulled switch knob.
Described rotation axis periphery is provided with secure ID.Secure ID can be arranged to " ON ", " OFF ", " opening " or printed words such as " passes ", is used for the switch safety instruction, avoids the user to get an electric shock, and guarantees user's safety.
Described shifting block lower end is provided with cushion pad.Cushion pad is the wear-resisting soft material that rubber or natural rubber are made; when switch cuts out; cushion pad can cushion the impulsive force of pulling under the switch knob; avoid that switch knob is permanent to be used and rupture; sound in the time of also can reducing simultaneously switch knob and close; when reducing noise, can also prolong the useful life of switch knob, fabulous protection switch knob.
Described groove is positioned at housing rear end face middle part and the groove two ends are provided with bayonet socket.Air switch when mounted available draw-in groove is located, and bayonet socket is used for the air switch chucking is prevented the air switch loose shift.
The invention has the advantages that:
1, the present invention is simple in structure, can be good at protecting switch knob and user, and fail safe is good.
2, safety durable switch knob of the present invention is set up board slot and cushion pad, and the noise when having reduced on-off switch has increased security performance and the useful life of switch knob.

Embodiment
Referring to Fig. 1, automatic air-break switch, comprise housing 1, housing 1 front end face middle part evagination forms boss, boss is provided with safety durable switch knob 2, and described housing 1 is equipped with screwed hole 3 in the end face of boss both sides, and described housing 1 arranged on left and right sides face is equipped with connection jaws 5, connection jaws 5 is communicated with screwed hole 3, and described housing 1 rear end face is provided with groove 4.
When implementing present embodiment, electric wire is inserted connection jaws 5, and at screwed hole 3 interior installation solidus bolts electric wire is fixed, by groove 4 the fixing chucking of switch is got final product; Present embodiment is simple in structure, changes original switch knob into safety durable switch knob 2, thereby has greatly prolonged fail safe and the useful life of switch knob.
Referring to Fig. 1, Fig. 2, present embodiment has been optimized the safety durable switch knob on the basis of embodiment 1, and its concrete structure is: described safety durable switch knob 2 comprises rotation axis 22, and rotation axis 22 peripheries are connected with shifting block 21.
In the present embodiment, rotation axis 22 axial restraints of safety durable switch knob 2, rotation axis 22 rotates when stirring shifting block 21, and not only switch is convenient, and useful life is more permanent.
Referring to Fig. 1-Fig. 3, present embodiment has been optimized following structure on the basis of embodiment 2, and specifically: described shifting block 21 upper surfaces are connected with board slot 211; Described rotation axis 22 peripheries are provided with secure ID; Described shifting block 21 lower ends are provided with cushion pad 212.
Than embodiment 2, present embodiment is connected with board slot 211 in shifting block 21 upper surfaces, and the user can be by on board slot 211 when pulling shifting block 21, safe safe durable switch knob 2 is pulled down; Rotation axis 22 peripheries are established secure ID, and the user can determine that switch cut-offs situation by secure ID, avoid getting an electric shock; Cushion pad 212 is established in shifting block 21 lower ends, can cushion the impulse force that shifting blocks are set aside by cushion pad 212, the noise when minimizing shifting block 21 is set aside, fabulous protection shifting block.
