Description

TECHNICAL FIELD The present invention relates to a fixing structure for an electric device that enables rail mounting and base mounting of the electric device.

2. Description of the Related Art When fixing electrical equipment with a control panel or the like, a method of fixing to a rail or a base is used as a fixing method.
When fixing electrical equipment to the rail, the movable piece is engaged and fixed to the fixed part of the rail, and the structure is such that the movable piece is removed from the rail. If you try to fix an electrical device that has a
Since the movable piece projects outside the electrical equipment, the metal fixture for fixing the base cannot be attached to the electrical equipment, and the movable piece must be removed or moved to a position where it does not interfere.

DISCLOSURE OF THE INVENTION Problem to be Solved by the Invention The present invention makes it possible to fix a rail or a base to a small electric device, and to hold the movable piece by pushing the movable piece of the electric device inward of the electric equipment. The thing that can fix the base is provided.

The present invention has a structure in which a spring piece of a movable piece mounted on the bottom surface of an electric device can be crossed over both the locking portion and the both-side locking portions, so that the rail fixing and the base fixing can be performed. Also, the movable piece can be easily moved.

Effect of the Invention In the present invention, since the movable piece of the electric device can be moved to the position where the rail is fixed or the base is fixed while the movable piece is held, it is necessary to remove the movable piece when changing from rail fixing to base fixing. It is easy to use because there is no need to manage moving parts.

EXAMPLE Hereinafter, referring to FIG. 1 to FIG. 6, 1 is an electric device having a recessed portion 2 on the bottom surface, and 3 is a locking portion locked on one side of the recessed portion 2 of a rail 4 having a sectional shape. It engages with one fixed part 5, 6
Is attached to the bottom surface of the electric device 1 facing the locking portion 3 with a movable piece, and the other fixed portion 7 of the rail 4 is attached to the engaging portion 9 of the movable piece 6.
, And sliding portions 8 are formed on both sides of the movable piece 6, and an operating portion 10 is provided at the opposite end of the movable piece 6 from the engaging portion 9. The movable piece 6 has a hole at a substantially intermediate portion between the operating portion 10 and the engaging portion 9.
A bridge-shaped bridging part 12 is integrally formed in the middle part of the hole 11, and spring pieces 13, 13 having one free end in the hole 11 are integrally formed on both sides of the bridging part 12. There is.

Reference numerals 14 and 14 denote sliding grooves in which the movable piece 6 is mounted at a position facing the locking portion 3 of the recess 2. The sliding portions 8 and 8 provided on both sides of the movable piece 6 are provided in the sliding grooves 14 and 14, respectively. Sliding engagement 15 and 15 are locking projections, and taper part 16 is provided on one side.
5 and 15 are formed at regular intervals and both sides have tapered portions 22 and 22 on both sides, and 19 and 19 are locking struts, which are formed at regular intervals from both side locking protrusions 17 and 17 to lock. The protrusions 15, the both-side locking protrusions 17, and the locking struts 19 are formed between the sliding grooves 14, 14 so as to face the locking portion 3 on the bottom surface of the electric device 1. Reference numeral 20 denotes a groove in which the operating portion 10 of the movable piece 6 is slidably engaged.

Next, a method of mounting the movable piece 6 on the bottom surface of the electric device 1 will be described. As shown in FIG. 1, the movable piece 6 is positioned in the recess 2 and the sliding portions 8 and 8 are slid in the arrow a direction. Inserting while inserting the moving grooves 14, 14 into the concave grooves 21, 21 of the movable piece 6,
While the locking projections 17 on both sides and the locking columns 19 pass, the spring pieces 13,
13 is mounted in the state shown in FIG. 4 by overcoming the taper portion 16 of the locking projections 15 and 15 and also over the one side taper portion 22 of the both-side locking projections 17.

When fixing the electric device 1 equipped with the movable piece 6 to the rail 4, the fixing portion 7 of the rail 4 is fixed while the fixing portion 5 of the rail 4 is fitted and locked in the locking portion 3 in the state shown in FIG. When the movable piece 6 is pressed against the taper portion of the engaging portion 9, the movable piece 6 moves outward and the ends of the spring pieces 13 and 13 are in contact with the locking columns 19 and 19. 13, 13 are deformed, the fixed part 7 is the engaging part 9
When entering between the bottom of the electric device 1 of the recess 2 and the electric equipment 1, the movable piece 6 is moved inward by the spring pieces 13 and 13, and the rail 4 is moved as shown in FIG.
The electric device 1 is fixed to the. When the electric device 1 is removed from the rail 4, a screwdriver or the like is put in the hole 27 of the operation portion 10 of the movable piece 6 to move the movable piece 6 to the outside, and the engagement between the fixed portion 7 and the engaging portion 9 of the rail 4 is performed. It can be removed by removing the connection.

Next, when the electric device 1 is mounted on the base, as shown in FIG. 6, the movable piece 6 is pushed inward so that the spring pieces 13 and 13 are locked on both sides with the locking projections 17, 17 and the locking projections 15, 17. The operation part 10 is moved between 15 and is held inside the electric device 1 without protruding to the outside of the electric device 1 with the movable piece 6 inside and the one end fixing part 24 of the mounting bracket 23 is fixed. It can be inserted into the fixed recess 25 and can be attached to the base. The movement of the movable piece 6 is made by
The spring pieces 13,13 were smoothly made by using the both side tapered portions 22,22 of the 7,17, and the spring pieces 13,13 were locked by the locking projections 15,15 and the movable piece 6 was pushed in. Can be held in position.

Effect of the Invention According to the present invention, the movable piece mounting portion of the electric device is provided with locking projections, both side locking projections, and locking struts at regular intervals, and one side of the locking projection is tapered and both sides of the locking projection are both tapered. As the taper part, the spring piece of the movable piece can be moved in the attachment / detachment direction of the rail fixing, so the movable piece can be easily moved to the rail fixing position and the base fixing position with the movable piece attached to the electrical equipment. When mounting the base, the base can be fixed while the movable piece is held on the electric device without removing the movable piece, and the rail can be fixed on the electric equipment without the need to manage parts of the movable piece. And there is an effect that the base can be fixed.
