The rotary switch comprises a plurality of layers of switch units, each layer of switch unit comprises a shell, and a moving contact and a static contact which are arranged in the shell, and the plurality of layers of switch units are arranged in a stacked mode through the shell. In the process that a moving contact and a static contact in a switch unit are changed from a closing state to an opening state, electric arcs can be generated in the shell, the normal work of elements in the shell can be influenced by the existence of the electric arcs, and the electric arcs need to be eliminated as soon as possible. The shell of the existing switch unit is limited by the size, the arcing space in the shell is small, and electric arcs can quickly leave the shell through the arcing space, so that the arc extinguishing effect is poor. In view of this, the present application is specifically proposed.
Referring to fig. 1 to fig. 3, in the present embodiment, an arc spraying opening 110 is disposed on a casing 100, an arc burning space 120 communicated with the arc spraying opening 110 is disposed in the casing 100, at least two separating ribs 130 extending toward the arc spraying opening 110 are disposed in the arc burning space 120, the separating ribs 130 are spaced apart from a sidewall 121 of the arc burning space, and two adjacent separating ribs 130 are spaced apart from each other.
The shell 100 provided in this embodiment is divided into an arcing space 120, and an inlet of the arcing space 120 is disposed corresponding to an area where the moving contact 210 and the stationary contact 220 generate an arc, so that the arc can enter the arcing space 120 to be extinguished. The side wall of the casing 100 is further provided with an arc spout 110 communicating with an outlet of the arc space 120, and an arc that is not extinguished in the arc space 120 is ejected through the arc spout 110 and leaves the casing 100.
In order to extinguish the arc as much as possible in the limited space of the arcing space 120 and improve the arc extinguishing effect of the casing 100, at least two separating ribs 130 are arranged in the arcing space 120, the separating ribs 130 extend from the inlet of the arcing space 120 to the outlet (the arc spraying opening 110) of the arcing space 120, and gaps are respectively arranged between the separating ribs 130 and the inner wall of the arcing space 120 and between two adjacent separating ribs 130 so as to separate the arcing space 120 into a plurality of arc extinguishing chambers. As shown by the arrows in fig. 2, after entering the arc burning space 120, the arc is shunted by the isolating rib 130 and enters different arc extinguishing chambers, outlets of the arc extinguishing chambers are converged into a whole and then communicated with the arc spraying opening 110, and finally, the arc which is not extinguished is sprayed out from the arc spraying opening 110.
The isolating ribs 130 elongate the arc, and extend the flow path of the arc in the arcing space 120, so as to slow down the ejection of the arc, keep the arc voltage in the housing 100 at a high state, and improve the arc extinguishing performance of the housing 100. Meanwhile, the side wall of the spacer 130 can accelerate the cooling of the electric arc, and has the effect of arc dissociation elimination.
It should be understood that the number of the ribs 130 may be two, three, four or more, and may be specifically set according to the size of the arcing space 120, as shown in fig. 2, when the number of the ribs 130 is two, the arcing space 120 is divided into three arc extinguishing chambers; as shown in fig. 3, when the number of the ribs 130 is three, the arcing space 120 is divided into four arc extinguishing chambers.
The housing 100 may be integrally formed, or the ribs 130 and other portions may be separately formed and then fixedly connected. The height of the spacer 130 cannot be too low, and should be equal to or slightly less than the thickness of the housing 100, so as to prevent most of the arc from directly moving above the spacer 130 to the arc spraying opening 110 to be sprayed out, which cannot improve the arc extinguishing performance of the housing 100, cool the arc and eliminate the arc.
As described above, in the housing 100 provided in this embodiment, at least two separating ribs 130 extending from the inlet of the arcing space 120 to the outlet of the arcing space 120 are disposed in the arcing space 120, so as to elongate the arc and slow down the ejection of the arc, thereby achieving high arc extinguishing performance, cooling the arc, and improving the arc dissociation effect.
Referring to fig. 2 and fig. 4, optionally, in an implementation manner of the embodiment of the present invention, a width of an inlet of the arcing space 120 is greater than a width of an outlet of the arcing space 120, the separating rib 130 includes a first end 131 and a second end 132, the first end 131 is disposed near the arc spraying opening 110, a distance between the first end 131 of the separating rib 130 near an inner wall of the arcing space 120 and the inner wall is smaller than a distance between the second end 132 of the separating rib 130 and the inner wall, and a distance between the first ends 131 of two adjacent separating ribs 130 is smaller than a distance between the second ends 132.

The distance between the first end 131 of the first type of spacer and the inner wall of the arcing space 120 (i.e. L in fig. 4) 1 ) Is smaller than the distance between the second end 132 of the first type of spacer and the inner wall of the arcing space 120 (i.e. D in fig. 4) 1 ) That is, the width of the inlet of the arc-extinguishing chamber between the inner wall of the arcing space 120 and the first type of spacer is greater than the width of the outlet. The distance between the first ends 131 of two adjacent spacers 130 (i.e., L in FIG. 4) 2 ) Is less than the distance between the second ends 132 (i.e., D in fig. 4) 2 ) That is, the width of the inlet of the arc-extinguishing chamber between two ribs 130 is greater than the width of the outlet.
The inlet of the arcing space 120 has a width greater than the outlet of the arcing space 120, and the inlet of each arc extinguishing chamber has a width greater than the outlet, in order to smoothly introduce the arc into it. And the shape of each arc extinguishing chamber is basically the same, so that the shunting capacity of each arc extinguishing chamber is basically consistent, and the arc is favorably and uniformly dispersed.
It should be understood that the spacer ribs 130 necessarily include the first type of spacer ribs, but may not include the second type of spacer ribs, for example, when the number of the spacer ribs 130 is two, the spacer ribs 130 include only the first type of spacer ribs; when the number of the spacer ribs 130 is three or more, the spacer ribs 130 include both the first type spacer ribs and the second type spacer ribs.

The first distance is the distance between the first end 131 of the first type of spacer and the inner wall of the arcing space 120, i.e. L in fig. 4 1 (ii) a The second distance is the distance between the first ends 131 of any two adjacent spacers 130, i.e. L in FIG. 4 2 (ii) a The first distance includes two, and the second distance may be 0, 1 or more, specifically determined according to the number of the spacer ribs 130. The sum of all the first distances and all the second distances is greater than the width of the arc opening 110 (i.e., D in fig. 4), so as to prevent the unburnt arc from being trapped in the arc space 120 and unable to be ejected from the arc opening 110, and the housing 100 from being burst due to excessive internal pressure.
For example, when the number of the partition ribs 130 is two, the first distance is two, and the second distance is 0, at this time, the sum of the two first distances is greater than the width of the arc spraying opening 110; when the number of the partition ribs 130 is three, the first distance is two, and the second distance is also two, and at this time, the sum of the two first distances and the two second distances is greater than the width of the arc spraying opening 110.
