Problems solved by technology

Such contactors generally only have one closed contact group unit or only one disconnected contact group unit, and it is impossible to achieve the coexistence of the two. In many cases, customers need to use both of them at the same time. function, for this reason, customers need to purchase additional accessories to achieve the purpose of function

Abstract

The invention relates to a contactor with multi-group contact units, comprising a foundation and a substrate. The middle part of the interior of the chamber of the substrate is provided with a supporting piece, the supporting piece is provided with moving contact components of a first group of contact units, the moving contact components of a second group of contact units are arranged on the supporting piece and at both sides or either side of the moving contact components of the first group of contact units; the moving contact components of a third group of contact units are arranged below the moving contact components of the second group of contact units; and the supporting piece is fixedly connected on a movable core and drives the moving contact components to contact or leave the corresponding static contact components along with the motion of the movable core. In the invention, secondary development is carried out on the basis of providing only one constantly open or constantly closed signal contactor, and another contact component is reasonable additionally arranged by adjusting the position and dimension of a control unit space, the supporting piece, the contact and a contact bridge, so that the contactor can be provided with the constantly open and constantly closed contact units at the same time.

Description

technical field [0001] The invention relates to a contactor, in particular to a contactor provided with multiple sets of contact units. Background technique [0002] AC contactors are mainly used to control the start and stop of AC motors and other important power control components that are electrically floating on and off. The contactor usually consists of a base and a base. The base is equipped with an E-shaped yoke, and the E-shaped yoke is equipped with a coil skeleton and a coil. The base is equipped with an E-shaped armature and a contact mechanism. The coil and the E-shaped A spring is arranged between the armatures, and the base is fixed with the base by screws. When in use, the external terminal is connected to the motor circuit, and the control terminal is connected to the control circuit. When the coil is energized, an alternating magnetic field is generated in the E-shaped yoke, and the E-shaped armature is attracted to the E-shaped yoke by the electromagnetic ...
