Description
Technical field
The present invention relates to a kind of A.C. contactor, especially a kind of A.C. contactor manual-operating mechanism, belongs to low tension
Gas class product manufacturing and applied technical field, when being mainly used in control line failure in Fire Fighting Pump Control cabinet, by there is pipe
Mechanical emergency of the personnel of reason authority when urgent starts fire pump, or other need mechanical emergency to start electricity under emergency conditions
The occasion of motivation..
Background technology
A.C. contactor is widely used in low-voltage circuit, be it is a kind of using it is safe, easy to control, measure big and wide work
Industry necessary.A.C. contactor is being switched on or switched off main circuit, to turn on control loop with auxiliary contact using main contact.It is main
Contact is usually normally opened contact, and auxiliary contact often has two pairs of normally opened contacts and normally-closed contact.The power of A.C. contactor action
The magnetic field that electric current is produced by ribbon core coil is derived from generally.
The operation principle of A.C. contactor is：In control circuit under normal circumstances, after ac contactor coil is powered, flow through
The electric current of coil can produce magnetic field, and the magnetic field of generation makes armature produce electromagnetic attraction attraction iron core, and drives A.C. contactor master
Contact action, normally-closed contact disconnect, normally opened contact closure, and both are linkages, connect major loop.Work as ac contactor coil
During power-off, the current vanishes in coil are flow through, the electromagnetic attraction of armature also disappears therewith, and armature is released in the presence of release spring
Put, disconnect major loop.As the power of A.C. contactor action is derived from the magnetic field that electric current is produced by ribbon core coil.Institute
In the case of breaking down in control circuit, conventional A.C. contactor loses the power source of action, makes the main contact cannot
Action.
Current existing A.C. contactor product, its power source is the magnetic field that electric current is produced by ribbon core coil.Can only
Be in control circuit under normal circumstances, after ac contactor coil is powered, the electric current for flowing through coil can produce magnetic field, generation
Magnetic field makes armature produce electromagnetic attraction attraction iron core, and drives AC contactor main contact action, and normally-closed contact disconnects, normally opened to touch
Point closure, both are linkages.Connect major loop.When ac contactor coil power-off, the current vanishes in coil are flow through,
The electromagnetic attraction of armature also disappears therewith, and armature is discharged in the presence of release spring, disconnects major loop.When in control circuit
In the case of breaking down, due to there is no coil of the electric current by ribbon core, so also just having no way of produces magnetic field at all.Without magnetic
, the driving source of A.C. contactor also can not be just produced, its so-called subsequent action just cannot be realized at all.
The content of the invention
To solve above-mentioned the deficiencies in the prior art, the invention provides a kind of A.C. contactor manual-operating mechanism.

(1), rotating shaft (2), axle sleeve (3), push rod (5), little axle sleeve (25), housing (6) it is connected with driven gear (10).Housing (6) with
Lid (24) is fixedly connected.Two fairleads (8), two torsion springs (9), driven gear (10), driving gears (11) are arranged on support
(17) in.Torsion spring (9) one end is arranged on fairlead (8), and the other end is arranged on driven gear (10).Driving gear (11) with
Driven gear (10) is engaged.Side body (13) is connected with support (17).End cap (18) is put in side body (13).Handle axis
(19) penetrate end cap (18) to be inserted in the square hole of driving gear (11), while being screwed into driving gear (11) with holding screw (16)
Screwed hole in, be relatively fixed driving gear (11), Handle axis (19) and end cap (18).Operation handle (20) and Handle axis
(19) connect.
Preferably, side plate (15) is additionally provided with the side of side body (13).
The present invention is not changing A.C. contactor agent structure and is not changing the premise of A.C. contactor itself function
Under, cleverly incorporate simple and direct, reliable, easy-operating manual-operating mechanism.A.C. contactor is realized in specific use environment
Under, when both control circuit breaks down, remain to realize the connecting and disconnecting of main contact.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
As shown in figure 1, A.C. contactor manual-operating mechanism, including cam (1), rotating shaft (2), axle sleeve (3), packing ring (4),
Push rod (5), housing (6), screw assembly A (7), fairlead (8), torsion spring (9), driven gear (10), driving gear (11), screw
Component B (12), housing 2 (13), screw assembly C (14), side plate (15), holding screw (16), support (17), end cap (18), handss
Arbor (19), operation handle (20), screw assembly D (21), lid (24), little axle sleeve (25).Above-mentioned lid (24) is screwed
On the support on the right side of A.C. contactor main body (22), catalyst main shaft (23) is through lid (24).Then by the nose circle of rotating shaft (2)
Through on lid (24), cam (1) and axle sleeve (3) are set in rotating shaft (2).Packing ring (4), push rod (5) and little axle sleeve (25) are set to and connect
After on tentaculum main shaft (23), housing (6) is anchored on lid (24), and is fixed with screw assembly A (7).By two fairleads
(8), two torsion springs (9), a driven gear (10), a driving gear (11) are arranged on support (17) by matching requirements.
Then side body (13) is anchored on support (17), and end cap (18) is penetrated in side body (13) and support (17), while set
To on driving gear (11), operating mechanism assembly is constituted.Operating mechanism assembly is anchored to into the correspondence position of housing (6), and
It is fixed with screw assembly B (12).Handle axis (19) are penetrated in the square hole of end cap (18) and driving gear (11), while using tightening
Screw (16) is screwed in the screwed hole of driving gear (11), makes driving gear (11), Handle axis (19) and end cap (18) relatively solid
It is fixed.Side plate (15) is snapped on side body (13), and is allowed to fixed with screw assembly C (14).Finally operation handle (20) is covered
To in Handle axis (19), and make operation handle (20) firm with Handle axis (19) fastening with screw assembly D (21).
Invention applies the accumulation of energy of gear spring accumulating mechanism spring connects through and off as AC contactor main contact
Start the power source of work.A.C. contactor main shaft is transferred the force to by cam push rod and bearing produces moment of torsion.By
Act on moment of torsion produced by bearing in A.C. contactor main shaft, then by A.C. contactor link gear band moving armature and main contact
Motion, realizes the connecting and disconnecting of AC contactor main contact.The energy stored by spring is accelerated release in vitro in moment, with people
External force for operation handle is unrelated, can be prevented effectively from arc discharge, and the electrical property of A.C. contactor connecting and disconnecting process is not had
There is a bit impact.
The manual-operating mechanism, its simple structure, simple operation reliability, install, it is easy to maintenance.Realize A.C. contactor
When control circuit breaks down, additionally it is possible to ensure that major loop is reliably switched on or switched off, be a application prospect widely, times
Product popular with users.
