Abstract

Disclosed embodiments relate to an auxiliary relay of an electronic contactor. In some embodiments, an auxiliary relay has its conducting state controlled by a plurality of lead switches, in a non-exposed state of contact parts to the outside. This may prevent dust or foreign materials from clinging to the contact parts.

First claim

What is claimed is:

1. An auxiliary relay of an electronic contactor, comprising:
a frame;
a movable member configured to move in the frame and including a magnet disposed on one side of the movable member;
a conducting member disposed in the frame and including a first switch unit and a second switch unit, wherein the first and second switch units conduct as the magnet moves;
a first terminal connected to the first switch unit and configured to apply a current when it is determined that the first switch unit is conducting;
a second terminal connected to the second switch unit and configured to apply a current when it is determined that the second switch unit is conducting; and
a plurality of guide rails disposed on two sides of the frame and configured to support the conducting member, and a hook disposed in the frame, wherein the hook is configured to contact one surface of the conducting member.

2. The auxiliary relay of an electronic contactor of claim 1 , wherein the first switch unit and the second switch unit comprise lead switches.

3. The auxiliary relay of an electronic contactor of claim 2 , wherein the conducting member comprises a printed circuit board (PCB).

4. The auxiliary relay of an electronic contactor of claim 1 , wherein the first terminal and the second terminal are configured to be inclined with a predetermined angle.

5. The auxiliary relay of an electronic contactor of claim 1 , further comprising a magnet inserting unit configured to fixedly-insert the magnet onto a side surface of the movable member.

6. The auxiliary relay of an electronic contactor of claim 5 , wherein the magnet inserting unit comprises front and rear surfaces that are open.
