A kind of rotary switch
Technical field
The present invention relates to a kind of rotary switch, belong to power consumption equipment field, terminal.
Background technology
At present in various power circuit process of deployment, except that equipment such as automatic air-break switch, knife switch, etc. the hand switch use amount also be very huge; Or even irreplaceable, this kind hand switch has simple in structure, and safe and stable equipment operation property is high; The characteristics of long service life are favored by deeply in market, but the conventional manual switch also exists the sealing structure poor performance simultaneously; Its insulating protection ability has been received great influence, especially can not fully adapt to the outdoor open-air instructions for use of using, conducting electricity conditions such as dust and high humidity environment, simultaneously; Its conductor inside connects cutter hub self the elastic deformation abilities that rely on more and connects; Also very easily cause the tie point contact area little or contact unsettled phenomenon, very easily cause phenomenons such as local pyrexia sparking, threaten supply line normally to move.
Summary of the invention
The object of the invention just is to overcome above-mentioned deficiency, and a kind of rotary switch is provided.
For realizing above-mentioned purpose, the present invention realizes through following technical scheme:
A kind of rotary switch comprises the rotary switch body, and described rotary switch is made up of housing, rotary body and conductor; Described housing side is arranged to few two cable-through holes, and upper surface is provided with rotating hole, and described rotary body is made up of handle, column spinner, stage clip and bridge connector; The column spinner two ends reliably are connected with stage clip with handle respectively, and bridge connector column spinner side and reliable the connection, it is inboard that described conductor is positioned at the housing cable-through hole; And reliably connect in housing; Described rotary body effectively is connected with housing through rotating hole, and wherein handle is positioned at hull outside, and column spinner, stage clip and bridge connector all place in the housing; Wherein bridge connector is positioned at conductor top, and stage clip reliably is connected with at the bottom of the housing.
Conductor and bridge connector constitute by at least four conductiving metal strips, and each bonding jumper is distributed in the same plane parallel with horizontal plane, and all establish insulation board between each bonding jumper and isolate.
The contact contact is set on the described bonding jumper.
Cable-through hole and rotating hole all are provided with elastic seal ring.
At least two of conductors.
The conductiving metal strip material is copper, aluminium, cupro lead, Kufil or lead-antimony alloy.
Housing, handle and column spinner material are hard insulation.
Stage clip is spring or shell fragment.
It is good that the present invention has the body seal performance, and the characteristics that the class of insulation is high improve the security protection performance greatly; Simultaneously; Its internal electric connecting portion contact stabilization is reliable, is difficult for becoming flexible or coming off, and has effectively reduced the resistance and the air gap of contact site; The spark phenomenon that has reduced the contact site caloric value and avoided causing because of loose contact has improved the safety and the stability of circuit operation.

Embodiment
As Fig. 1 with shown in, a kind of rotary switch comprises the rotary switch body; Described rotary switch is made up of housing 1, rotary body and conductor 2, at least two cable-through holes of described housing 1 side setting 3, and the upper surface center is provided with rotating hole 4; Described rotary body is made up of handle 5, column spinner 6, stage clip 7 and bridge connector 8, and column spinner 6 two ends reliably are connected with stage clip 7 with handle 5 respectively, and bridge connector 8 is connected with column spinner 6 sides; Described conductor 2 is positioned at housing 1 cable-through hole, 3 inboards and reliably connects in housing 1; Described rotary body effectively is connected with housing 1 through rotating hole 4, and handle 5 is positioned at housing 1 outside, and column spinner 6, stage clip 7 and bridge connector 8 all place in the housing 1 and be positioned at conductor 2 centre positions; Stage clip 7 reliably was connected with 1 end of housing; Conductor 2 and bridge connector 8 constitute by at least four conductiving metal strips 9, and each bonding jumper 9 is distributed in the same plane parallel with horizontal plane, and all establish insulation board 10 between each bonding jumper and isolate; Contact contact 11 is set on the bonding jumper, and cable-through hole and rotating hole all are provided with elastic seal ring 12.
During use; At first the both sides lead reliably is connected with conductor through cable-through hole; Then handle is pressed down and rotation, bridge connector is arrived and conductor downside and corresponding with it position, loose one's grip then; Rotary body rises because of the elastic force effect of stage clip and drive axle junctor and conductor compress, thus circuit turn-on; When the needs open circuit, with under the handle by and rotation make bridge connector rotate to no conductor position, loose one's grip then, rotary body gets final product open circuit because of the elastic force effect of stage clip rises to no conductor position.
