Embodiment 1

[0028] refer to figure 1 As shown, this embodiment is a circuit breaker, which, like existing circuit breakers, includes a housing 6, usually made of plastic, which is composed of two half-shell structures snapped together (for clarity expression, a half-shell structure is removed in the figure), the housing 6 is installed with a first terminal 63, a magnetic assembly 631, a static contact 632, an interlock mechanism, and a second terminal 64; the first terminal 63 , the magnetic assembly 631 and the static contact 632 are electrically connected in series in sequence, and the second terminal 64 is electrically connected to the free end of the bimetal 4 of the interlocking mechanism through a conductive copper sheet and a flexible connection copper wire to form a controllable Wiring group.

[0029] The housing 6 is also installed with an operating member 62. In this embodiment, the operating member 62 is a knob pivotally connected to the housing 6, and the second end of the in...

Embodiment 2

[0044] This embodiment discloses an electronic control device for protecting circuits or personnel, including the interlock mechanism described in the first embodiment above or other alternative variant embodiments listed in the first embodiment, and the locking component is configured to work with Triggered by the trigger end of the electronic control device, the relative moving contact assembly swings around the axis. For example, the locking component of the interlock mechanism can be associated with a manual emergency button. When the operator presses the emergency button, the locking component is triggered to swing around the axis relative to the moving contact component, and the locked state of the locking structure is released. Of course, the lock assembly can also be triggered by electronic control of the equipment circuit, equipment interlocking trigger or mechanical trigger, etc., all of which can realize the function of circuit and personnel protection.

Abstract

The invention relates to an interlocking mechanism, an electric control device with the same and a circuit breaker. An adjustment structure is arranged on a driving arm of the interlocking mechanism, the relative position of the driving arm and a free end is changed by the adjustment structure, so that the position of a bimetallic sheet is relatively adjustable, and the technical problem of low production efficiency and product yield since the bimetallic sheet cannot be adjusted in the prior art is solved.

Description

technical field [0001] The present invention relates to the general technical field of circuit equipment, and more specifically, the present invention relates to a control wire or switch, an interlock mechanism for protecting personnel or equipment, electric control equipment and a circuit breaker equipped with the interlock mechanism. Background technique [0002] The circuit breaker for line protection includes two terminals connected to the line, and a disconnectable circuit is arranged between the two terminals; the disconnectable circuit includes a moving contact, a static contact, and a switch for controlling the position of the moving contact. The interlock mechanism also includes a thermally sensitive disconnected bimetal for protecting the circuit from overload and an electromagnetic disconnecting part containing a coil; the coil of the electromagnetic disconnecting part has a plunger-type iron core connected to the push rod, which is When the line is short-circuite...
