Description
Technical field
The utility model relates to a kind of A.C. contactor, especially a kind of A.C. contactor hand-operating device, belong to the manufacture of low-voltage electrical series products and applied technical field, when being mainly used in control line failure in Fire Fighting Pump Control cabinet, start fire pump by the mechanical emergency having the personnel of administration authority when urgent, or other needs the occasion of mechanical emergency actuating motor under emergency conditions.。
Background technology
A.C. contactor is widely used in low-voltage circuit, is a kind of use safety, controls conveniently, measures large and wide industrial necessity.A.C. contactor utilizes main contact to be switched on or switched off main circuit, carrys out conducting control loop with auxiliary contact.Main contact is generally 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 normally comes from the magnetic field that electric current is produced by ribbon core coil.
The operation principle of A.C. contactor is: at control circuit under normal circumstances, after ac contactor coil energising, the electric current flowing through coil can produce magnetic field, the magnetic field produced makes armature produce electromagnetic attraction attraction iron core, and driving AC contactor main contact action, normally-closed contact disconnects, and normally opened contact closes, both are interlocks, and major loop is connected.When ac contactor coil power-off, flow through the current vanishes in coil, the electromagnetic attraction of armature also disappears thereupon, and armature discharges under the effect of retracting spring, and major loop is disconnected.Power due to A.C. contactor action comes from the magnetic field that electric current produced by ribbon core coil.So when control circuit breaks down, conventional A.C. contactor loses the power source of action, makes 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 at control circuit under normal circumstances, when after ac contactor coil energising, the electric current flowing through coil can produce magnetic field, the magnetic field produced makes armature produce electromagnetic attraction attraction iron core, and drives AC contactor main contact action, and normally-closed contact disconnects, normally opened contact closes, and both are interlocks.Major loop is connected.When ac contactor coil power-off, flow through the current vanishes in coil, the electromagnetic attraction of armature also disappears thereupon, and armature discharges under the effect of retracting spring, and major loop is disconnected.When breaking down at control circuit, owing to there is no electric current by the coil of ribbon core, so also just have no way of produce magnetic field at all.Do not have magnetic field, also just can not produce the driving source of A.C. contactor, its so-called subsequent action just cannot realize at all.
Utility model content
For solving above-mentioned the deficiencies in the prior art, the utility model provides a kind of A.C. contactor hand-operating device.
For achieving the above object, the technical solution adopted in the utility model is: A.C. contactor hand-operating device, comprises lid (24), cam (1), rotating shaft (2), axle sleeve (3), little axle sleeve (25), push rod (5), housing (6), fairlead (8), torsion spring (9), driven gear (10), driving gear (11), support (17), side body (13), end cap (18), Handle axis (19) and operating grip (20).Lid (24) is fixed on the support on the right side of A.C. contactor main body.Contactor main shaft is successively through through lid (24), cam (1), rotating shaft (2), axle sleeve (3), push rod (5), little axle sleeve (25), housing (6) being connected with driven gear (10).Housing (6) is fixedly connected with lid (24).Two fairleads (8), two torsion springs (9), driven gear (10), driving gears (11) are arranged in support (17).Torsion spring (9) one end is arranged on fairlead (8), and the other end is arranged on driven gear (10).Driving gear (11) engages with driven gear (10).Side body (13) is connected with support (17).End cap (18) is put in side body (13).Handle axis (19) penetrates end cap (18) and is inserted in the square hole of driving gear (11), use holding screw (16) to be screwed in the screwed hole of driving gear (11) simultaneously, make driving gear (11), Handle axis (19) relative fixing with end cap (18).Operating grip (20) is connected with Handle axis (19).
Preferably, side plate (15) is also provided with in the side of side body (13).
The utility model do not change A.C. contactor agent structure and do not change A.C. contactor self function prerequisite under, incorporated simple and direct, reliable, easy-operating manual-operating mechanism cleverly.Achieve A.C. contactor under specific environment for use, when both control circuit breaks down, still can realize the connecting and disconnecting of main contact.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, A.C. contactor hand-operating device, comprise 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 assembly B (12), housing 2 (13), screw assembly C (14), side plate (15), holding screw (16), support (17), end cap (18), Handle axis (19), operating grip (20), screw assembly D (21), lid (24), little axle sleeve (25).Above-mentioned lid (24) is screwed on the support on A.C. contactor main body (22) right side, and contactor main shaft (23) is through lid (24).Then by the nose circle of rotating shaft (2) through lid (24) on, 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 after on contactor main shaft (23), housing (6) is anchored on lid (24), and is fixed with screw assembly A (7).Two fairleads (8), two torsion springs (9), driven gear (10), driving gears (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), be set on driving gear (11), composition operating mechanism assembly simultaneously.Operating mechanism assembly is anchored to the correspondence position of housing (6), and fixes with screw assembly B (12).Handle axis (19) is penetrated in the square hole of end cap (18) and driving gear (11), use holding screw (16) to be screwed in the screwed hole of driving gear (11) simultaneously, make driving gear (11), Handle axis (19) relative fixing with end cap (18).Side plate (15) is snapped on side body (13), and makes it fixing with screw assembly C (14).Finally operating grip (20) is set in Handle axis (19), and makes operating grip (20) and Handle axis (19) firmly fastening with screw assembly D (21).
The utility model applies the power source of accumulation of energy as the connecting and disconnecting action of AC contactor main contact of gear spring accumulating mechanism spring.By cam push rod, force transmission is produced moment of torsion to A.C. contactor main shaft and bearing.Due to A.C. contactor main shaft and torsional interaction that bearing produces, then by A.C. contactor link gear band moving armature and main contact motion, achieve the connecting and disconnecting of AC contactor main contact.The energy that spring stores is being accelerated release in vitro instantaneously, has nothing to do, effectively can avoid arc discharge, not have a bit impact to the electrical property of A.C. contactor connecting and disconnecting process with the external force of manual operation handle.
This manual-operating mechanism, its structure is simple, simple operation is reliable, installs, easy to maintenance.Achieve A.C. contactor when control circuit breaks down, can also ensure that major loop is reliably switched on or switched off, be a application prospect widely, product doubly popular with users.
