Description
Technical field
It the utility model is related to field of circuit breakers, and in particular to a kind of rotating shaft mechanism of breaker.
Background technology
The rotating shaft mechanism of breaker generally comprises a rotating shaft matrix and moving in the cavity of rotating shaft matrix is touched
Head, the contact of moving contact front end and static contact are engaged.In the course of the work, dynamic/static contact band produces the structure when electrically disconnected
Electric arc be easily accessible in cavity, so as to being caused damage to the miscellaneous part in cavity, influence the functional reliability of breaker.
Utility model content
In order to overcome the shortcomings of background technology, the utility model is provided after one kind prevents electric arc and altered, and simple in construction, work can
By the rotating shaft mechanism of the high breaker of property.
Technical scheme used by the utility model：A kind of rotating shaft mechanism of breaker, it include rotating shaft, several side by side
Moving contact in the rotating shaft and the torsion spring of the connection rotating shaft and moving contact, set on the axial direction of the rotating shaft
There is the cavity that several are placed equidistant, be designed with being available for the torsion spring to be socketed in each cavity and be available for the moving contact to cut with scissors
The connecting shaft connect, the rotating shaft are provided with the protector for being used for protecting the torsion spring.
The protector uses and the integrally formed first baffle of the rotating shaft.
The protector is using the removable second baffle in the rotating shaft.
The protector uses the protective cover being arranged in the rotating shaft.
The rotating shaft, which is provided with, to be used to contradict and limit the limiting section of the moving contact slewing area.
The moving contact is provided with groove, and the torsion spring is provided with the U-shaped circle being engaged by clamping with the groove.
The beneficial effects of the utility model are：By setting protector in rotating shaft, electric arc can be completely cut off, electric arc is avoided and blow
To torsion spring and blow torsion spring, have increase the service life, simple in construction, security is good, improve functional reliability the advantages of.

Embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings：
As illustrated, a kind of rotating shaft mechanism of breaker, it includes rotating shaft 1, several are mounted side by side in the rotating shaft 1
Moving contact 2 and the torsion spring 3 of the connection rotating shaft 1 and moving contact 2, the axial direction of the rotating shaft 1 is provided with several etc.
Cavity 11 away from setting, each it is designed with being available for the torsion spring 3 to be socketed in the cavity 11 and is available for what the moving contact 2 was hinged
Connecting shaft 4, the rotating shaft 1 are provided with the protector for being used for protecting the torsion spring 3, by setting protector in rotating shaft, can completely cut off
Electric arc, avoid electric arc and blow to torsion spring and blow torsion spring, have and increase the service life, simple in construction, security is good, improves work
The advantages of reliability.
Embodiment one：The protector uses and the integrally formed first baffle 5 of the rotating shaft 1.
Embodiment two：The protector is using the removable second baffle 6 in the rotating shaft 1.
Embodiment three：The protector uses the protective cover 7 being arranged in the rotating shaft 1.
The rotating shaft 1, which is provided with, to be used to contradict and limit the limiting section 12 of the slewing area of moving contact 2, the moving contact
2 are provided with groove 21, and the torsion spring 3 is provided with the U-shaped circle 31 being engaged by clamping with the groove 21.
Embodiment is not construed as the limitation to utility model, but it is any be based on spiritual improvements introduced of the present utility model,
All should be within the scope of protection of the utility model.
