Description

(54) ВЫКЛОЧАТЕЛЬ МГНОВЕННОГО ДЕЙСТВИЯ(54) Instant Action Tap

1one

Изобретение относитс к электротехнике , в частности к коммутационным аппаратам, предназначенным дл применени в автоматизированных системах управлени , защиты и сигнализации электроприводов машин и механизмов .The invention relates to electrical engineering, in particular, to switching devices intended for use in automated control systems, protection and alarm systems for electric drives of machines and mechanisms.

Известен выключатель мгновенного действи , содержащий неподвижные контакты/ закрепленные на изол ционном основании, последовательно соединенные друг с другом приводной и контактный рычаги и пружину. Приводной рычаг и пружина закреплены на изол ционном основании f11.An instantaneous action switch is known, which contains fixed contacts / fixed on an insulating base, which are connected in series with each other by driving and contact levers and a spring. The drive lever and spring are fixed on the insulating base f11.

В известном выключателе контактное давление при движении приводного элемента до точки срабатывани измен етс от номинальной величины до нул , что ограничивает его область применени либо делает ненадежным работу при медленных скорост х,движени при водного элемента.In the known switch, the contact pressure, when the drive element moves to the trigger point, varies from nominal value to zero, which limits its field of application, or makes unreliable work at slow speeds, movement at the water element.

Известен также выключатель мгновенного действи , содержащий изол ционное основание, неподвижные контакты, закрепленные на изол ционном основании , приводной рычаг, один конец 5 которого закреплен на изол ционном основании, контактный рычаг с.«подвижным контактом на свободном конце и два промежуточных рычага, которые соединены между собой одними своими кон цами, на одном из указанных концов промежуточных рычагов выполнены зацепы , которые упираютс в контактный рычаг, другой конец одного из промежуточных рычагов также упираетс в Контактный рычаг 2 оAn instantaneous switch is also known, which contains an insulating base, fixed contacts mounted on an insulating base, a drive lever, one end 5 of which is fixed on the insulating base, a contact lever with a "moving contact on the free end and two intermediate levers that are connected between each other with their ends, at one of the indicated ends of the intermediate levers there are hooks which abut against the contact lever, the other end of one of the intermediate levers also abuts against K ntaktny lever 2 on

Такой выключатель имеет значительные габариты.Such a switch has significant dimensions.

Цель изобретени - уменьшение габаритов . ;The purpose of the invention is to reduce the size. ;

Claims

The delivered chain is achieved by the fact that in the switch of instantaneous action containing an insulating base, fixed contacts, fixed, 10 prisoners on the insulating base, a driving lever, one end of which is fixed on the insulating base, a contact lever with a movable contact at the free end and two intermediate levers which are interconnected by one ends, on one of the indicated ends of the intermediate levers, hooks are made which rest against the contact lever, the other end of one of the intermediate levers that Also, the contact lever abuts, the hooks abut against the free end of the contact lever, the indicated other end of one of the intermediate levers abuts against the other end of the contact lever, and the other end of the second intermediate lever is attached to the insulating base, the other end of the drive lever is connected to the contact a lever between the contact points of the contact lever with intermediate levers, one of the levers being made spring-loaded. In FIG. 1 shows the instantaneous action switch, first embodiment; in fig. 2 — details of the power switch in FIG. one; FIG. 3 shows a switch, the second embodiment, and FIG. k — details of the switch in FIG. 3 in FIG. 5 is a switch, the third embodiment of J in FIG. 6 - the same, the fourth embodiment. The momentary action switch contains fixed contacts 1 (fig. 1), fixed to the insulating base 2, connected to each other drive 3, contact two intermediate 5 and 6 levers, one of the levers is spring-loaded. One end 7 of the drive lever 3 is fixed on the insulating base.

2. One of the intermediate levers 5 and 6 is made with hooks 8, with which it rests against the free end 9 of the contact lever ha 4, carrying movable contacts 10. One end 11 of the intermediate lever 5 is fixed on the insulating base 2, and the other end 12 of the intermediate lever 6 is connected to the end 13 of the contact lever 4. The other end k of the drive lever 3 is connected to the contact lever k, 4 between the junction points of the contact lever A and the intermediate levers When an external force F acts on the drive lever 3 and the junction intersects the drive lever arm 3 with a contact lever k conditional line 1-1 occurs movable contact switching. When removing the external force from the drive lever, all moving parts occupy the initial position. Formula of the invention. An instantaneous action switch containing an insulating base, fixed contacts mounted on an insulating base, a driving lever, one end of which is fixed on the insulating base, a contact arm with a movable contact. at the free end and two intermediate levers, which are interconnected by one ends, at one of the specified ends of the intermediate levers, hooks are made, which connects to the contact lever, the other end of one of the intermediate levers also abuts against the contact lever, characterized in that in order to reduce its dimensions, the hooks abut against the free end of the contact lever, said other end of one of the intermediate levers abutting the other end of the contact lever, and the other end of the second intermediate lever is fixed on the insulating base, the other end of the drive lever is connected to the contact lever between the connection points of the contact lever with the intermediate levers, while one of the levers is made spring.
