Embodiment Construction

[0025] In FIG. 1 , a control device D according to the invention for the contacts of an electrical switching device, such as a switch or a circuit breaker, can be seen. This device comprises a first assembly shown in Figure 2, said assembly comprising a camshaft 1 articulated to a frame, said shaft being firmly rotatably attached to a cam 2, said first assembly also comprising A guide rod 3 is also connected to the machine frame in an articulated manner by means of its one end (initially referred to as the first end) 3a. These parts are connected to each other by a roller 4 slidingly mounted in a curved groove 5 of the cam 2 and comprising a pin 6 firmly attached to a rod 7 . This rod 7 is slidably mounted in the channel 8 and is fixed via its end opposite to the end connected to the roller 4 to a movable contact (not shown) of the device. This channel 8 also comprises a housing 9 designed to accommodate a spring 10 which presses via its one end 10a on the inner surface 8a of...

Abstract

The invention relates to a device for controlling the opening and / or closing of the electrical contacts in an electrical apparatus and electrical apparatus containing such a device. The device comprises a crank capable of being driven to rotate by a control mechanism, a compression spring (16) and a connecting rod (12). According the invention, the device comprises a compression crank (14) and an operating crank (11) that are connected with respect to a frame in a articulatably manner. The crank (14) is articulatably connected to an upper end of a compression spring (16) and is driven to rotate by an operation control mechanism. The crank (11) is connected articulatably to a connecting rod (12), and comprises a mechanism for driving the crank (11) by the crank (14) after passage of the spring beyond a dead point passage position to change position of a contact, and a mechanism for retaining the contact in an initial position during compression of the spring before passage of the spring beyond the passage position.

Description

technical field [0001] The invention relates to a control device for controlling the opening and / or closing of contacts in electrical equipment, the device comprising an operating crank, a compression spring and a connecting rod, wherein the operating crank is articulated relative to the machine The frame is connected and can be driven by the control mechanism to rotate between a first position corresponding to the closed position of the contacts and a second position corresponding to the open position of the contacts, The compression spring is hingedly connected to the crank via one of its ends, called the first end, and mechanically connected via its opposite end, called the second end, to the movable contact, the The connecting rod is connected in an articulated manner to the crank via one of its ends, called the first end, and mechanically connected via its opposite end, called the second end, to the movable contact, the spring being capable of Its first end is compressed...
