Abstract

The utility model relates to a double knife switch consisting of a back shell, a swinging cover and two power switching devices, with each power switching device has a contact point tip, a frame tip and a springboard. A static contact point is fixed on the contact point tip, and a static contact point is fixed on head of the springboard. The spring takes head of the frame tip as a pivot. Under pressure of steel balls in two symmetric columnar cylinders under the swinging cover, two groups of dynamic and static contact points contact or depart. The two contact point tips and frame tips which are respectively and parallel installed on the back shell are vertical to swing plane of the swinging cover. A clapboard is arranged between the two power switching devices so to separate and insulate two circuits form each other. The clapboard also helps reducing electromagnetic interference and preventing shortcut. The utility model can control power conditions of both live wire and zero wire. The utility model is suitable using in circuits which resist crossed wires, taking a circuit board in need of controlling each socket respectively. The utility model is characterized in simple structure, convenient installation and connection as well as reliable and secure performance.

Description

Double-pole switch

Technical field

The utility model relates to a kind of appliance switch, especially a kind of double-pole switch.

Background technology

Usually small-sized appliance switch all is the switching by the incompatible control live wire of the branch of one group of dynamic and static contact.This traditional appliance switch, a carelessness slightly in practical operation, easily with the appliance switch reversal connection on circuit, so just cause the contact pin to be connected with zero line, switch is used for controlling the break-make of zero line, so the indication neon lamp on the switch can only show the break-make of zero line, and live wire still is in on-state with electrical equipment always, make electrical equipment charged all the time, can cause great potential safety hazard to the person like this.In order to adapt to market demand, a kind of double-pole switch with two groups of break-make switching device shifters comes out.Two groups of contact pin of this double-pole switch and stent foot one in front and one in back symmetry are installed under the drain pan side by side, though can control the break-make of live wire and zero line simultaneously, but if the circuit of specific (special) requirements is arranged with its control, especially the electric wire circuit that should not intersect, for example need to control along separate routes each socket on the terminal block, connection between them is cumbersome, and is short-circuited easily.For this reason, people expect to invent a kind of break-make that can control live wire and zero line simultaneously, can be used to control the circuit connection convenience of specific (special) requirements again, the double-pole switch that performance is safe and reliable.

Summary of the invention

The purpose of this utility model is at the defective of prior art and deficiency, can control live wire and zero line simultaneously for providing of appliance switch industry is a kind of, and is easy to install again, the double-pole switch that performance is safe and reliable.

Technical solution adopted in the utility model is: this double-pole switch comprises that drain pan, pendulum cover and be fixed on two groups of break-make switching device shifters of being made up of contact pin, stent foot and springboard on the drain pan, fixed contact is fixed on the pin of contact, moving contact is fixed on the end of springboard and corresponding up and down with fixed contact, springboard is a fulcrum with the stent foot end, steel ball below the pendulum lid in the cylindrical tube of two symmetries compresses down, make two groups of dynamic and static contact clutches, forward and backward successively alternate being installed in parallel on the drain pan of described contact pin and stent foot, and perpendicular with the swinging plane of pendulum lid; Between two groups of break-make switching device shifters that described contact pin, springboard and stent foot are formed dividing plate is housed; One end of described dividing plate is inlaid in the groove that is arranged on base end, and its bottom is plugged on the pillar that is arranged on base by location hole; The other end of described dividing plate is established a quarter bend, and it is isolated with stent foot and another stent foot.

The utility model double-pole switch can be controlled the break-make of live wire and zero line simultaneously, especially on the circuit that suitable electric wire should not intersect, for example need to control along separate routes the terminal block of each socket, its connection is convenient and safe reliable, for the appliance switch industry has increased a kind of switch new varieties again.

Embodiment

As shown in the figure, this double-pole switch comprise drain pan 10, pendulum cover 2 with drain pan 10 on successively forward and backward alternate parallel installation contact pin 12,12 ' with

stent foot

13,13 '.Be fixed with fixed contact 11,11 ' respectively on this

contact pin

12,12 '.Moving contact 14,14 ' is separately fixed at springboard 9,9 ' end.This springboard 9,9 ' can be respectively that fulcrum rotates with the folded end in stent foot 13, the 13 ' drain pan.The neon lamp seat 3 that pendulum cover 2 below is fixedlyed connected with the pendulum lid, and two cylindrical tube and the neon lamp seat that are positioned at left and right symmetry below the pendulum lid fuse, and are with spring 5,5 ' in the pipe respectively, and the steel ball 4,4 ' below it compresses mutually with springboard 9,9 ' respectively.Cover swing by pendulum, steel ball 4,4 ' is slided before and after springboard 9,9 ' is gone up respectively under the elastic reaction of spring, thereby make moving contact closed with fixed contact on the pin of contact or separate, make the while switching of live wire and zero line.For the energising that shows electrical equipment whether, neon lamp 6 is housed in neon lamp seat 3, its two ends, neon lamp 6 series resistors, 7 back are attempted by on the stent foot respectively.Be arranged with lampshade 8 at Bai Gai, lampshade 8 is bright, to show the electrical equipment energising.

As Fig. 4, shown in Figure 5, for the mutual isolated insulation of two road circuit is come, reduce mutual electromagnetic interference, prevent short circuit, at contact pin 12, springboard 9, the break-make switching device shifter that stent foot 13 is formed with by contact pin 12 ', springboard 9 ', between another group break-make switching device shifter that stent foot 13 ' is formed dividing plate 1 is housed, the end of dividing plate 1 is inlaid in the groove 15 that is arranged on the drain pan end, the bottom of dividing plate is provided with location hole, and be plugged on by this location hole on the pillar of drain pan, the other end of dividing plate is established a quarter bend 16, and it is isolated with stent foot 13 and stent foot 13 '.

During use, it is installed in the terminal block, every double-pole switch contact pin links to each other with the haptic element of socket by conductive plate respectively.As long as before and after press bottom lid, live wire and the zero line switching of control switch simultaneously, thus control each socket on the terminal block respectively, the circuit when having avoided like this connecting intersects, and installs more conveniently thereby make, the use safety and reliability has been guaranteed personal safety.
