The present invention relates to a relay, and more particularly, to a relay that can be easily coupled to a frame by combining a movable member that provides elasticity to an armature that is coupled to the frame and contacts a large current by magnetic force, thereby improving convenience in assembly. It is about.

In general, a relay uses a small current to control a large current circuit on / off and its configuration is as shown in FIG. 1. 1 is a perspective view showing a conventional relay.

 As shown in Fig. 1, the conventional relay configuration is coupled to an armature (3) and an armature (3) which flows by the magnetic force of the electromagnet (2) and the armature (3) which generate magnetic force in response to the application of an electric current. It consists of a movable member (4) to provide elasticity to 3).

Here, the electromagnet 2 is fixed to the frame 1 of the form surrounding the electromagnet 2, and one end of the movable member 4 is fixed to the frame 1. And the other end is fixed to the armature (3) to drive the contact so that a large current can be energized by the magnetic force when the electromagnet (2) is formed a magnetic field, the movable member (4) when the magnetic field of the electromagnet (2) is removed To be returned by elasticity.

At this time, the movable member 4 is fixed to the frame 1, but in order to fix mainly to the frame 1, the coupling hole 5 is provided in the frame 1 and the movable member 4, and then overlaps to fix the riveting method. After forming the coupling protrusion of the cylindrical shape in the frame 1, the coupling hole 5 is formed in the movable member 4, the coupling hole 5 is inserted into the coupling protrusion, and then the coupling protrusion is compressed and fixed.

In this case, when the coupling holes 5 are formed in the frame 1 and the movable member 4, it is difficult to match the coupling holes 5 with each other. When the coupling hole 5 is formed in the movable member 4 after the coupling protrusion is formed in the frame 1, the coupling is complicated, and the coupling hole 5 of the movable member 4 is coupled to the coupling protrusion. The projections should be compressed, but there is a problem that the movable member 4 does not maintain the fitted state before pressing the projections and is easily separated.

The present invention was created in view of the above necessity, and an object of the present invention is to provide a relay that is coupled with a movable member to a frame and can be fixed at the same time, thereby improving convenience of assembly.

In addition, it is an object of the present invention to provide a relay having improved elasticity by improving the fluidity of the movable member when the movable member is coupled to the frame.

The relay of the present invention for achieving the above object is a frame in which an electromagnet is installed, an armature for contacting a circuit with magnetic force on the electromagnet, and a movable fixed to the frame to return the armature to its original position when the magnetic force of the electromagnet is released. And a hook protrusion provided on the member and the frame, the hook protrusion being fixed to the movable member at the same time, and a locking bar provided on the movable member and fixed to the hook protrusion.

Here, the hook protrusion is formed to protrude from the frame, it is preferable that the locking groove is formed in close contact with the frame side so that the locking bar is caught and fixed.

And it is preferable that the locking bar has an insertion hole into which the hook protrusion is inserted at one side of the locking bar so as to be fixed by elasticity, and an elastic hole is formed at the other side.

In addition, the locking bar is provided on both sides with respect to the insertion hole, it is preferable that the insertion hole the locking bar is formed with an elastic hole, respectively.

And it is preferable that the inclined portion is provided so that the locking bar is coupled to the hook protrusion only in the insertion direction and is not caught.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the description of the present invention, terms defined are defined in consideration of functions in the present invention, it should not be understood as a meaning limiting the technical components of the present invention.

At this time, a movable contact is provided on one side of the armature 30 so that a large current can be contacted when attached or separated by a magnet, and the movable contact is connected to a large current plug 50 protruding forward. And not shown fixed contact is fixed to the housing 70 to which the frame 10 is coupled.

In addition, the movable member 40 is provided to return to the original position when the magnetic field of the electromagnet 20 is removed. One end of the movable member 40 is coupled to the armature 30, the other end is coupled to the frame 10. And it is provided with an elastic material so as to have a predetermined elasticity.

Movable member 40 is provided in the form of "a" and the horizontal end is riveted or bolted or welded to the armature 30. And the vertical end is extended by extending both sides of the width direction. At this time, in order to hook the movable member 40 to the frame 10, the engaging bar 41 is provided on the movable member 40, and the hook protrusion 11 is provided on the frame 10.

The hook protrusion 11 is formed to protrude from the frame 10, the cross-sectional area of the end is provided larger than the cross-sectional area of the frame 10 side. That is, the locking groove 12 is formed in close contact with the frame 10 so that the locking bar 41 can be caught and fixed. In addition, the hook protrusion may be formed in a cylindrical shape.

The locking bar 41 is provided to be thin so as to be caught by the locking groove 12, and is provided to have a diameter or width and a thickness of 0.5 to 2 mm or less. In addition, an insertion hole 42 into which the hook protrusion 11 is inserted is formed at one side of the locking bar 41 so that the locking bar 41 can be caught in the locking groove 12, and the locking bar 41 is centered. As such, the elastic hole 43 is formed at the other side.

Accordingly, the locking bar 41 has elasticity and improved fluidity, so that the locking bar 41 is formed in the locking groove 12 formed in the hook protrusion 11 at the vertical end in the state where the armature 30 is coupled to the horizontal end. When the insert is inserted, the fixing is primarily completed, and rivets or bolts can be fastened through the coupling holes 44 provided at both sides for more firm fixing.

And when the rivet or bolted through the coupling hole 44 is the first fixed state does not require a separate fixing work.

Hereinafter, the operation according to the coupling of the movable member 40 according to an embodiment of the present invention will be described with reference to FIG. 4. 4a to 4c is an operating state diagram showing the coupling of the movable member 40 according to an embodiment of the present invention.

First, as shown in FIG. 4A, the armature 30 is coupled to the horizontal end of the movable member 40. In this case, the armature 30 is preferably provided in a fixed state is coupled to the movable member 40 for ease of assembly.

Thereafter, as shown in FIG. 4B, the locking bar 41 of the movable member 40 is hooked to the hook protrusion 11. At this time, the hook protrusion 11 is inserted into the insertion hole 42, the locking bar 41 is easy to insert the hook protrusion 11 by improving the fluidity of the locking bar 41 while generating bending to the elastic hole 43 side. Let's do it.
