But, existing with automatic reclosing circuit breaker otherwise there is no arrangement of clutch or the volume of arrangement of clutch too too fat to move, increase the overall volume of switch, even moreover the arrangement of clutch that satisfies condition also fails to get a desired effect, be that manual operation power is still very large, the ill effect existence such as fluctuation of service are even arranged.
Summary of the invention
The present invention seeks to: the arrangement of clutch in a kind of compact conformation, flexible circuit breaker simple to operate is provided.
Technical scheme of the present invention is: a kind of arrangement of clutch for circuit breaker, comprise the rotating shaft and the clutch that contain the chamber that runs through up and down, offer connecting hole on the base of described rotating shaft, described clutch comprises connector and lower connector, lower connector is connected with the transmission shaft driven of motor, be provided with a plurality of springs between described lower connector and motor, described upper connector device is located at above lower connector, and its mutual interlock, upper connector offers through hole along axis, and upper connector is fixedly connected in chamber.
Preferably, the D type hole that described power transmission shaft and described lower connector are offered is in transmission connection, and the top in described D type hole is provided with a T-shaped axle, and the lower end of described T-shaped axle is greater than its upper end, and the upper end of described T-shaped axle is nested in described upper connector.
Preferably, described lower connector top is provided with a plurality of lower tooths, offers the upper tooth with the lower tooth phase interlock of lower connector on described upper connector.
Preferably, the side of described upper connector is provided with projection, and described projection is snapped in the groove that is opened in correspondence position in chamber.
Preferably, the quantity of described spring is two.
Preferably, the base cross section of described rotating shaft is circular.
Preferably, the upper part of described chamber is the hexagonal through hole, and below it, position is manhole.
Preferably, the external diameter of described lower connector is greater than the external diameter of described upper connector.
Small and exquisite and the manual operation of compact conformation, the volume of the arrangement of clutch that is used for circuit breaker that provides by such scheme and electric operating are changed very convenient, only need operating grip is inserted in hexagon ring and presses downwards, under T-shaped axial compression, make connector and lower connector break away from, just can convert manual operation to from electric operating.The present invention is particularly useful on the smaller and more exquisite circuit breaker of volume ratio, certainly also is applicable on the moderate or larger circuit breaker of moulding shell band automatic reclosing of volume.In addition, as long as structure is amplified, also be applicable on any product that is needed simultaneously clutch by motor drives.

Embodiment
Principle of the present invention is to set up one can carry out from electric operating and convert manually operated arrangement of clutch in the rotating shaft of motor.
Embodiment:
To shown in Figure 6, the power transmission shaft of motor A is connected with the D type hole 3a that the lower end of lower connector 3 is offered, and is provided with two springs 5 between lower connector 3 and motor A as Fig. 1, and lower connector 3 tops are provided with eight lower tooth 3b; Offer the upper tooth 2a with the lower tooth 3b phase interlock of lower connector 3 on upper connector 2, the external diameter of upper connector 2 is less than the external diameter of lower connector 3, upper connector 2 offers through hole along its axis, the top of D type hole 3a is provided with a T-shaped axle 4, the lower end of T-shaped axle 4 is greater than its upper end, the upper end of T-shaped axle 4 is nested in connector 2, and the side of upper connector 2 is provided with protruding 2b, and protruding 2b is snapped in the groove that is opened in correspondence position in chamber 1b; Rotating shaft 1 section be shaped as the font of falling T, have the chamber 1b of a up/down perforation along the axis of rotating shaft 1, the upper part of chamber 1b is hexagonal through hole 1a, operating grip B can insert in hexagonal through hole 1a, the following position of chamber 1b is manhole, the base cross section of rotating shaft 1 is circular, offers connecting hole 1c on it, and it is connected with output shaft.
When the present embodiment carries out electric operating, spring 5 holds up lower connector 3, upper connector 2 is in interlocking pattern with lower connector 3, when motor A rotated, the D profile shaft drove lower connector 3 and rotates, upper connector 2 masticatory movements, rotating shaft 1 is along with upper connector 2 rotates, be connected to the also rotation thereupon of output shaft on connecting hole 1c, drive circuit breaker and carry out spring energy-storage, reach the purpose of divide-shut brake; When needs carry out manual operation, operating grip B is inserted in hexagonal through hole 1a, and press downwards, T-shaped axle 4 is depressed, make lower connector 3 and upper connector 2 break away from, rotating operation handle B then, rotating shaft 1 is rotated thereupon, the same circuit breaker that drives carries out spring energy-storage, reaches the purpose of divide-shut brake; Conversion is very convenient between electric operating and manual operation like this, and arrangement of clutch compact conformation, volume are small and exquisite, are applicable to most of motor A.
