Embodiment Construction

[0017] refer to figure 1 , 2 , the contactor is provided with a base 30 and a base 20, the base 20 is provided with a support (not shown in the figure), a return spring 94 and a static contact, and the support is provided with a movable contact (not shown in the figure), the base 30 is provided with a coil 80, a fixed armature 81, and a pair of command terminals 82a, 82b, and is also provided with a cavity 31 that can accommodate the control circuit board 60. When the voltage of the coil 80 rises When it reaches a certain value, the suction force is generated between the fixed armature 81 and the movable iron core to move the support member downward. On the contrary, when the voltage of the coil 80 drops to a certain value or when the power is cut off, the fixed armature 81 and the movable iron core are in the position of the return spring 94. Under the action of tension, the supporting part is driven to reset.

Abstract

The disclosed contactor comprises: a bottom base, including a coil with a movable iron core, a fixed armature, a command terminal, and a control circuit board with input and output end connected with the command terminal and coil; and a base frame, including a support member with a moving contact to connect with former core, a reset spring, and a fixed contact.

Description

technical field [0001] The invention relates to a contactor. Background technique [0002] The existing contactor includes a base and a base, the base is provided with a support, a return spring and a static contact; the base is provided with a coil, a fixed armature and a command terminal; the support A movable contact is provided, and a movable iron core is arranged inside the coil, and the movable iron core is fixedly connected to the supporting member; both ends of the command terminal are respectively connected to the coil and an external control circuit. When the command terminal receives the energization signal of the external control circuit, the voltage signal is added to the coil. After the coil is energized, a suction force is generated between the fixed armature and the movable iron core to move the supporting member downward, so that the movable contact and the static contact Closed (for normally open contacts) or open (for normally closed contacts). Conversel...
