Description

(5) ЭЛЕКТРОВЫКЛОЧАТЕЛЬ(5) ELECTRIC SWITCH

1 .one .

Изобретение относитс к электротехнике , а более конкретно к выключател м с угловым перемещением оргаьюв управлени .The invention relates to electrical engineering, and more specifically to switches with angular movement of control units.

Известен выключатель, в котором переключение происходит за счет пр молинейного перемещени подвижного контакта к неподвижным контактом, закрепленным в основании корпуса 1.A switch is known, in which switching takes place due to a straight-line movement of the moving contact to the fixed contact fixed in the base of the housing 1.

Наиболее близким к изобретению ,Q вл етс электрический выключатель, который содержит электроизол ционный корпус с наход щимс в нем органом (органами) управлени в виде кулачка и контактами, выползненными в плоских пружин, которые вход т в (Соприкосновение при повороте кулачка 2.Closest to the invention, Q is an electrical switch that contains an electrically insulating housing with a cam-shaped control body (s) and contacts crawled into flat springs that come in (The contact when the cam 2 rotates.

Недостатком данного переключател вл етс то, что контакт между двум пластинчатыми упругими кон- 20 тактами осуществл етс простым соприкосновением , незначительное оседание пыли на Контактах может служить причиной отказа, так как отсут твует прюцесс самозачистки. В случае ослаблени упругих свойств пластинчатых контактов сам кулачок не помогает размыкать контакты, т.е. нет гюдстраховки .The disadvantage of this switch is that the contact between the two plate-shaped elastic contacts is simple contact, a slight dust settling on the Contacts can cause failure, since there is no self-cleaning process. In the case of the weakening of the elastic properties of the plate contacts, the cam itself does not help to open the contacts, i.e. There is no insurance.

Целью изобретени вл етс повышение надежности контактов.The aim of the invention is to increase the reliability of the contacts.

Claims

This goal is achieved by the fact that, in a switch comprising a body made of electrically insulating material j, controls installed with the possibility that, on a common axis fixed in the body and lamellar elastic contacts fixed at the base of the body, the base of the body is made with a curved surface; elastic contacts are arcuate ({jurma in the middle part, ka) the adherent control is made with depressions under the arcuate part of the lamellar elastic contacts and three protrusions, two of which are started to act on the said arcuate 3 .9 areas of plate elastic contacts VfOB .a third - to open them, plate elastic contacts are made with the possibility of moving towards each other, so that the working part of one of them moves relative to the working part of the other, while one of plate elastic contacts located on the curved surface of the base of the Corus. Figure 1 shows the circuit breaker in the open state; Figure 2 is the same in the intermediate state; fig. 3 - the same, in the closed state; figb-switch, a general view in axonometry. The switch consists of an electrically insulating body 1, on the axis 2 of which at least one control unit 3 is mounted in the form of a cam, and there are fixed elastic contacts and 5 in the base of the body, having an arcuate shape in the middle part, the ends of which are led through the bottom of the base housing, each control is made with protrusions 6.7 and 8. The switch operates as follows. When the control unit 3 is rotated from the open state (Fig. 1) to the intermediate one (Fig. 2), the elastic contact k is first affected by the protrusion 6, causes it to move towards the contact 5, while the elastic contact k finds the contact 5 After some time when the contact k starts to move along the contact 5, the protrusion 8, acting on the convex part of the contact 5, pushes towards the contact k. In this way, the first self-cleaning slide between contacts is made. Upon further rotation of the control 3 from the intermediate state (, FIG. 2) into the closed (FIG. 3) protrusion 8 passes the top of the convexity of the elastic contact 5, the end of which is in contact with the contact C and imposes a reverse movement on a certain amount, not disconnecting the resulting electrical circuit. Proxy secondary pro; process x x suits. In the closed state, the protrusion 8 is located behind the bulge of the elastic contact 5 (Fig. 3) and the switch is fixed in the closed state. The protrusion 7 serves as a safety net: in the case of a weakening of the elastic properties of the contact 4, the protrusion 7 opens the electrical circuit, acting upon the reverse movement on the elastic contact k. An electric switch comprising a body of insulating material, controls mounted with the possibility of tilting on a common axis fixed in the body, and lamellar elastic contacts fixed at the base of the body, characterized in that, in order to increase reliability, the base of the body is made curvilinear surface. The plate-shaped elastic contacts are arcuate in the middle part, each control is made with cavities under the arcuate part of the plate-shaped elastic contacts and three protrusions, two of which are intended to act on the aforementioned arcuate sections of the plate-like elastic contacts, and the third is designed to open plates -: resilient elastic contacts, said plate elastic contacts are installed with the possibility of moving towards each other, so that the working part of one of them moves tnositelno GoGo each working part, wherein one of the resilient contact plate located on the curved surface of the base body.
