Casing inner space makes the technological deficiency of the static contact short circuit positioned at contact shell both sides, provides a kind of rotary switch
Shell insulation system is dielectrically separated from boss structure by being added in the inner cavity of contact shell, not only enhances striking function, more
The exhaust outlet that the electric arc of generation is effectively guided into contact shell is added to exclude；The electric arc of generation is hindered simultaneously from switch one end
The recessed empty region of stationary contact casing moves to the static contact of the other end, so as to avoid the short circuit of both ends static contact.
Technical solution
In order to achieve the above technical purposes, the shell insulation system of a kind of rotary switch of the utility model design, it
Including adjacent upper contact head shell and lower contact shell, the upper contact head shell and the superposition of lower contact shell are fitted together, special
Sign is：On the bottom surface of groove corresponding with moving contact on the upper contact head housing bottom downwards moving contact direction stretch out every
It is convex to stretch out isolation for upward moving contact direction on bottom surface from the moving contact mounting groove on boss one or the lower contact shell
Platform two.
Preferably, the isolation boss one and isolation boss two are round boss.
Preferably, the isolation boss one and isolation boss two are insulation boss.
Further, the isolation boss one and corresponding be placed in moving contact of about two boss of isolation form electric arc between the two
Isolation structure.
Further, notch can be equipped on the isolation boss one and isolation boss two.
Advantageous effect
The shell insulation system of a kind of rotary switch provided by the utility model, by increasing in the inner cavity of contact shell
If being dielectrically separated from boss structure, striking function, the significantly more efficient row that the electric arc of generation is guided into contact shell are not only enhanced
Gas port excludes；Simultaneously after moving contact insulating trip scaling loss, the electric arc of generation is hindered from the recessed dead zone of stationary contact casing of switch one end
Domain moves to the static contact of the other end, so as to avoid the short circuit of both ends static contact.

Embodiment 1
As shown in Fig. 1, the shell insulation system of a kind of rotary switch, it include adjacent upper contact head shell 1 and under
Contact shell 2, the upper contact head shell 1 and the superposition of lower contact shell 2 are fitted together, wherein as shown in Fig. 2, described tactile
The isolation of 3 direction of moving contact stretching downwards is convex on the bottom surface 101a of groove corresponding with moving contact 3 101 on 1 bottom of casing
Moving contact 3 upward on the bottom surface 201a of one 101a01 of platform or the moving contact mounting groove 201 on the lower contact shell 2
Isolation boss 2 202 is stretched out in direction.In the present embodiment, the groove corresponding with moving contact 3 on 1 bottom of upper contact head shell
Isolation one 101a01 of boss is stretched out in 3 direction of moving contact downwards on 101 bottom surface 101a, meanwhile, on the lower contact shell 2
Moving contact mounting groove 201 bottom surface on upward 3 directions of moving contact 201a stretch out isolation boss 2 202, electricity is collectively formed in the two
Arc isolation structure.
One 101a01 of isolation boss and isolation boss 2 202 are round boss.
One 101a01 of isolation boss and isolation boss 2 202 are insulation boss.
