Abstract
In the process of switching from a closed state to an open state, the movable contact is pulled away from the fixed contact by mechanical force, and an insulating partition plate is inserted into a gap between the corresponding fixed contact and the movable contact through rotation or movement; after the mechanical force disappears, the movable contact is close to the fixed contact under the action of the reset force, the insulating partition plate stops between the fixed contact and the movable contact at the moment, so that the movable contact cannot be contacted with the fixed contact under the support of the insulating partition plate, the switch is in a disconnected state, the movable contact and the fixed contact are separated by the insulating partition plate, the distance between the contacts is the thickness of the insulating partition plate (0.3-0.8 mm), therefore, the stroke of the switch can be designed to be very small, and the volume of the switch is reduced accordingly. With the insulating plate completely covering the stationary contact, the isolation voltage of the switch contact is higher. When the switch is in an off state, acting force for pulling away the movable contact is not required to be applied, and the requirement of reset elasticity is reduced.
Description
Technical field
The present invention relates to a kind of contact switch structure, more particularly, it relates to a kind of contact switch structure that is used to make appliance switch, relay.
Background technology
The electric equipment products such as switch, relay and contactor of present contact structure; Its off-state is that moving contact is drawn back the certain distance of fixed contact; In order to solve between fixed contact and the moving contact arc phenomenon that electric field produces when the static state; The distance that the contact is drawn back is followed the rising of operating voltage and is strengthened, thereby the volume that causes contact switch increases.So this contact switch structure is difficult to design the contact switch product of high voltage, small size.
Summary of the invention
Problem to be solved by this invention is the shortcoming that overcomes prior art, provides that a kind of volume is little, compact conformation, reliability is high, operating voltage is high contact switch structure.
Construction of switch of the present invention is to be achieved through following proposal, and is a kind of contact switch device controlled, comprises fixed contact, moving contact, fixed contact terminal, moving contact terminal and insulating barrier.Forwarded in the process of off-state by closure state at switch, mechanical force is pulled away from fixed contact with moving contact, also insulating barrier is passed through to rotate or move the gap of inserting between corresponding fixed contact and the moving contact simultaneously; After mechanical force disappeared, moving contact was drawn close to fixed contact under the effect of reset force, because insulating barrier is parked between fixed contact and the moving contact at this moment, so moving contact can't be contacted with fixed contact by the support of insulating barrier, switch is in off-state.
The present invention is owing to adopt technique scheme, and when switch was in off-state, moving contact and fixed contact are insulated dividing plate kept apart; Distance between the contact is exactly the thickness (for 0.3-0.8mm) of insulating barrier; So it is very little that the stroke of switch can design, the volume of switch also and then dwindles.Adopt the insulation board that covers fixed contact fully, the isolation voltage of switch contact is just higher.Switch need not to apply the active force that is pulled away from moving contact when off-state, also just lowered the requirement of reseting elasticity.

Among the figure: 1, fixed contact terminal, 2, moving contact, 3, fixed contact, 4, the moving contact terminal, 5, insulating barrier.
Specific embodiments
Below in conjunction with accompanying drawing the present invention is done following detailed description.
The described single-pole single-throw(SPST contact switch structure of Fig. 1 comprises: fixed contact terminal 1, moving contact 2, fixed contact 3, moving contact terminal 4, insulating barrier 5.An insulating barrier and a rotating shaft link into an integrated entity, when switch carries out closure and break function conversion, and the tip side of mechanical force pulling moving contact terminal, through the rotating shaft that is transferred to of power, insulating barrier swings up and down under rotating shaft drives simultaneously.When switch was in closure state, insulating barrier swung to the below of contact, and when switch was in off-state, insulating barrier was inserted between the sound contact.
Fig. 2 is described to be that one two single-pole single-throw contact switch structure comprises: fixed contact terminal 1, moving contact 2, fixed contact 3, moving contact terminal 4, insulating barrier 5.Two insulating barriers and a rotating shaft symmetry link into an integrated entity; Rotating shaft is located at two groups and touches in the middle of the terminal; When switch carries out the conversion of closure and break function, the tip side of mechanical force pulling moving contact terminal, the rotating shaft that is transferred to through power simultaneously; Insulating barrier is done the stepping of 90 degree and is rotated under rotating shaft drives.When switch was in closure state, insulating barrier forwarded two groups to and touches the middle neutral gear of terminal position, and when switch was in off-state, insulating barrier was inserted between the corresponding sound contact.
Embodiment 3
The described triple-pole single throw contact switch structure of Fig. 3 comprises: fixed contact terminal 1, moving contact 2, fixed contact 3, moving contact terminal 4, insulating barrier 5.Six insulating barriers and a hollow rotating shaft link into an integrated entity; Hollow rotating shaft one end is provided with the straight moving helical teeth that rotates that becomes; When switch carries out the conversion of closure and break function, the tip side of mechanical force pulling moving contact terminal, the rotating shaft that is transferred to through power simultaneously; Insulating barrier is done 30 degree steppings and is rotated under rotating shaft drives.When switch was in closure state, insulating barrier forwarded two groups to and touches the middle neutral gear of terminal position, and when switch was in off-state, insulating barrier was inserted between the corresponding sound contact.
Contact switch structure of the present invention, because switch over travel is little, compact conformation is fit to make the appliance switch that high voltage, bistable relay that volume is little, push-button switch etc. have the contact.
