Description
Technical field
The invention belongs to the switching technique field, especially relate to a kind of novel auto purification type rotary switch.
Background technology
Rotary switch is to rotate a kind of switch that rotary body is controlled the main contacts break-make, and common rotary switch comprises the contact chip with fixed contact and the rotary body with armature contact.By rotary body drive on it conducting ring be switched on or switched off at the contact chip with fixed contact, reach conducting or cut off the function of circuit.Rotary body is CONTACT WITH FRICTION between conducting ring and the contact chip in the process of rotating, and this process can be removed the slight corrosion, dirt on electric conductor surface etc., therefore becomes by " auto purification type switch ".
For example, as shown in Figure 1, have in the rotary switch of said structure, the outer surface of conducting ring 2 protrudes from the outer surface of rotary body 1, when therefore conducting ring is contact chip 3 rotating contact, conducting ring 2 can promote contact chip 3 radial displacement occurs, and the pressure of the stage clip 4 in contact chip 3 outsides increases at this moment, thereby the load meeting that causes rotary body 1 to need to overcome in rotation process increases; On the other hand, because contact chip 3 is defined the position by a bolt that runs through 5 in this rotary switch, motion on the vertical direction can not occur in contact chip 3, therefore switch is in the process that is switched on or switched off, relative motion can not occur with wiring pin 6 in contact chip 3, can not realize " self-cleaning " function between contact chip 3 and the wiring pin 6.
Summary of the invention
The problem to be solved in the present invention provides the constant pressure that a kind of novel auto purification type rotary switch, especially rotary body bear in rotary course, and can realize certain " self-cleaning " effect between contact chip and the wiring pin.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of novel auto purification type rotary switch, comprise that a switch case, is rotatably installed in the rotary body in the described switch case, one is embedded in the conducting ring of described a rotating body, two contact chips that are positioned at the described rotary body left and right sides, two stage clips that lay respectively at two described contact chip outsides, two respectively with described two wiring pins that the contact chip inside lower end contacts;
Further, described switch case inside has a fixed block, and the inboard of described two identical wiring pins is connected with described fixed block;
Further, described rotary body is cylinder, it is positioned on the end face of described switch case and has the groove identical with described conducting ring shape, described conducting ring is embedded in the described groove, described conducting ring has two identical circular arc sides, and the radius of described two circular arc sides is identical with the radius of described rotary body;
Further, described contact chip comprises the first contact-segment, supporting section and the second contact-segment, and described the first contact-segment is inboard to be contacted with described rotary body, and the described supporting section outside is connected with described stage clip, the inboard and outer side contacts of described wiring pin of described the second supporting section;
Further, an end of described each stage clip connects a described contact chip, and the other end of described stage clip is fixed on the described switch case inwall;
Further, described wiring pin comprises canned paragraph and wiring section, and described canned paragraph inboard is fixed on the described fixed block, and its outside, upper end connects and its described contact chip at the fixed block homonymy, has a connection bolt on the described wiring section.
Advantage and good effect that the present invention has are: owing to adopt technique scheme, rotary body is in the process of rotation, conducting ring can not promote contact chip generation radial displacement, the constant pressure of the stage clip in the contact chip outside, the load value that rotary body need to overcome when rotating is constant, is conducive to prolong the useful life of rotary switch; On the other hand, contact chip is in quick condition in described switch case, when rotary body drives the conducting ring rotation, conducting ring and contact chip CONTACT WITH FRICTION, under the drive of frictional force, between the contact chip that is in quick condition and the corresponding wiring pin slight reciprocating motion can occur, realize the self-purification functions such as cleaning corrosion, dirt.That the present invention has is simple in structure, easy to maintenance, long service life, many contact points realize the advantages such as self-cleaning function.

Embodiment
As shown in Figure 2, the invention provides a kind of novel auto purification type rotary switch, comprise that a switch case, is rotatably installed in the rotary body 1 in the described switch case, one is embedded in the conducting ring 2 of described a rotating body, two identical contact chips 3 that are positioned at the described rotary body left and right sides, two identical stage clips 4 that lay respectively at two described contact chip outsides, two respectively with the identical wiring pin 6 of described two contact chip inside lower end contact, described two identical contact chips 3, stage clip 4 and wiring pin 6 distribute respectively in switch case axisymmetricly;
Switch case inside has upper chamber, lower chambers and always puts on the fixed block 7 of lower chambers, the wiring pin that has described rotary body, conducting ring, contact chip, stage clip and part in the upper chamber, described bottom chamber has the other part of described wiring pin, and described fixed block is between described two wiring pins;
Rotary body is cylinder, it is positioned on that end of described upper chamber and has the groove identical with the conducting ring shape, conducting ring is embedded in the described groove, and conducting ring is comprised of two identical circular arc sides and a bottom horizontal, and the radius of two circular arc sides is identical with the radius of rotary body;
Contact chip comprises the first contact-segment, supporting section and the second contact-segment, and described the first contact-segment is inboard to be contacted with rotary body, and the supporting section outside is connected with described stage clip, and the second supporting section is inboard to be contacted with wiring pin, and its bottom contacts with described upper cavity;
