Specific embodiment
In order to be further understood that the summary of the invention of the utility model, this reality is elaborated below in conjunction with specific embodiment
With novel.
As depicted in figs. 1 and 2, the utility model provides a kind of single-pole contactor of small size, including lower case 1, on
Shell 6, dustproof cover 15 and contactor assembly, the upper end of the lower case 1 is connect with the lower end of the upper housing 6, described dust-proof
Lid 15 is covered on the upper end of the upper housing 6, and three forms the intermediate closed structure for accommodation space, and the contactor assembly is set
It sets in the accommodation space of the lower case 1, the upper housing 6 and the dustproof cover 15 composition, the contactor assembly packet
Include static magnet 2, coil 3, moving magnet 5, interlocking lever 8, dynamic touch panel 9 and static contact panel 14, the moving magnet 5, the static magnet 2 and institute
It states coil 3 to be arranged in the lower case 1, reaction spring 4, the dynamic magnetic is set between the static magnet 2 and the moving magnet 5
Connecting hole is set on iron 5, and the connecting hole is connect with the pin 7, can be fixed by the moving magnet 5 by the pin 7
In the lower case 1, interlocking lever 8 is riveted on the moving magnet 5, the bottom of the interlocking lever 8 is cube structure, middle part
Position is cylindrical structure, and top is prism structure, which not only can reduce the volume of the interlocking lever 8, can also be mentioned
The service life of the high interlocking lever 8, the interlocking lever 8, the dynamic touch panel 9 and the static contact panel 14 are arranged at the upper casing
In body 6, contact spring 11 is set on the dynamic touch panel 9, contact spring is set between 11 lower end of contact spring and the dynamic touch panel 9
Pedestal 10, contact spring cap 12 is arranged on the contact spring 11, and the contact spring cap 12 is fixed on the gearing by self threading pin 13
Bolt is arranged on the static contact panel 14 for the upper end of bar 8, and the bolt can be used to fix the bus copper sheet of major loop, while
Installation for contactor.
When power supply is connected, the coil 3 is powered on, and the static magnet 2 generates electromagnetic attraction, and the moving magnet 5 overcomes described
The elastic force of reaction spring 4, Xiang Suoshu static magnet 2 move；Since fixation is inconjunction with the interlocking lever 8, institute inside the moving magnet 5
With the moving magnet 5 movement, it will drive the interlocking lever 8 that the moving magnet 5 is followed to move downward；Again due to the dynamic touch panel 9
