Abstract

The utility model relates to a multi-conductor power switch which can simultaneously turn on or turn off a power live wire and a zero line. The utility model separately and electrically connects the external live wire and the zero line with a thread-clamping bolt, a movable contact spring and a fixed contact spring orderly in an insulating outer shell of a socket. When a button is pressed, an unguiform pushing wheel counterclockwise rotates an angle of 45 degree, and pushing rods on the two sides push the movable contact springs on the two sides simultaneously to tightly stick or turn off with the fixed contact spring and finish the action of the socket from closing (or opening) to opening (or closing) the power supply simultaneously. When the button is loosened, the button can automatically restore, but the pushing rod of the unguiform pushing wheel keeps the original shape. If the power supply is turned on, the pushing rod keeps using the downward thrust to press the movable contact spring all the time, thereby preventing a contact from heating to deform or displace after turning on and causing the electric contacting of the contact to be stable and reliable. The utility model has simple structure and few parts, and is easy for industrialized manufacturing.

Description

The multiconductor mains switch

Affiliated technical field

The utility model relates to a kind of switching device of universal power supply socket.

Background technology

At present, known supply socket switch all is a lead that turns on and off in power firestreak and the zero line.What be difficult to its shutoff of assurance in actual applications is live wire, and particularly mobile socket is all the more so.If what turn-off is zero line, just there are hidden dangers such as the possibility of electric leakage and receptacle sockets be charged in the on line electrical appliance during it does not use.

Summary of the invention

Though in order to overcome existing blanket socket power cutoff but there is the charged hidden danger of jack in essence, the utility model provides a kind of multiconductor mains switch, it can turn on and off live wire and zero line simultaneously, and electrically contacts reliable and stable.

The technical scheme that the utility model technical solution problem is adopted is: in the socket insulation crust, outer live wire and the zero line of introducing is electrically connected in proper order with line pressing bolt, movable contact spring, fixed touching plate respectively.Movable contact spring, the claw type push boat above the fixed touching plate can be rotated counterclockwise around the push boat axle, and there is push rod claw type push boat both sides, and it being opened and closing the braking of rotation time control synchronously contact, fixed touching plate.Each service position of the push rod of claw type push boat all is subjected to the location pit of claw type push boat both sides and the locking of corresponding push boat location hole, retainer spring, place kick, so keep the stable of its shape and position, when contact contacts, has limited the distortion or the displacement of contact.Button above the claw type push boat promotes the claw type push boat by predetermined orientation and angular turn.Because fixed touching plate links to each other with jack, so behind power cutoff, all jacks are all not charged.

The beneficial effects of the utility model are: can turn on and off the live wire and the zero line that enter socket simultaneously, it is all not charged to guarantee to close the jack of having no progeny, thereby gets rid of recessive hidden danger.This apparatus structure is simple, electrically contacts reliable and stablely, and easily industrialization is made.

Among the figure, 1, the socket loam cake, 2, following of socket, 3, button, 4, button spring, 5, the button inner cap, 6, interior bonnet bolt, 7, the claw type push boat, 8, push boat axle, 9, movable contact spring, 10, fixed touching plate, 11, the contact positioning boss, 12, termination, 13, the moving plate reference column, 14, the moving plate spring, 15, moving plate alignment pin, 16, line pressing bolt, 17, the push boat location hole, 18, retainer spring, 19, place kick, 20, the location pit.

Embodiment

In Fig. 1, termination (12) is inserted in outer lead-in conductor termination, after line pressing bolt (16) is fastening, with movable contact spring (9), fixed touching plate (10) and be positioned at socket loam cake (1) and socket following (2) with jack connect, this moment, socket such as Fig. 1 were in on-state.Press button (3), button (3) promotes claw type push boat (7) and is rotated counterclockwise miter angle, the push rod of claw type push boat (7) leaves movable contact spring (9) respectively simultaneously from both sides, movable contact spring (9) breaks away from fixed touching plate (10) under the effect of moving plate spring (14), both sides fixed touching plate (10) and the jack that links cut off the power supply simultaneously, thereby finish once action when being energized to outage.Release button (3), button (3) resets under the effect of button spring (4), and claw type push boat (7) at as shown in Figure 2 push boat axle (8), be positioned at retainer spring (18), the place kick (19) of push boat location hole (17) dress of following (2) both sides of socket, maintain the original state under the acting in conjunction of the location pit (20) of claw type push boat (7) both sides.Press button (3) again, repeat above-mentioned action after, when finishing once from cut off the power supply to switching on the action.Interior as shown in Figure 1 bonnet bolt (6) is used for button inner cap (5) is fixed in socket loam cake (1).Contact positioning boss (11) is positioned at following (2) two bottom sides of socket, and behind the good fixed touching plate to be installed (10), available flatiron irons contact positioning boss (11), makes fixed touching plate (10) location.After moving plate spring (14) is inserted in moving plate reference column (13), put movable contact spring (9) again, plug moving plate alignment pin (15) at last.Behind power connection because the push rod of claw type push boat (7) remains with downward thrust and pushes down movable contact spring (9), prevent heating distortion or the displacement of contact after energising, so that electrically contacting of contact is reliable and stable.

Claims

1. multiconductor mains switch, in the socket insulation crust, outer live wire and the zero line of introducing, be electrically connected in proper order with line pressing bolt, movable contact spring, fixed touching plate respectively, it is characterized in that: movable contact spring, the claw type push boat above the fixed touching plate can be rotated counterclockwise around the push boat axle, there is push rod claw type push boat both sides, and it being opened and closing the braking of rotation time control synchronously contact, fixed touching plate.

2. multiconductor mains switch according to claim 1, it is characterized in that: each service position of the push rod of claw type push boat all is subjected to the location pit of claw type push boat both sides and the locking of corresponding push boat location hole, retainer spring, place kick, so keep the stable of its shape and position, when contact contacts, the distortion or the displacement of contact have been limited.
