Description

[Detailed explanation of the idea] 〔Technical field〕 This invention relates to panel-mounted equipment.

[Background technology]

For example, some devices such as timers and counters (hour meters, etc.) are equipped with a mounting flange 12 on the front side of a box-shaped device body 11, as shown in FIG. This device is installed by inserting the device main body 11 into the hole 14 of the mounting panel 13 so that the mounting flange 12 comes into contact with the front surface of the panel 13. If the device is lightweight, it is fixed from the back using a simple and inexpensive setting spring 15.

The set spring 15 is generally attached to the device in advance to prevent it from being lost. However, since the width of the set spring 15 is larger than the width of the hole 14, it cannot be attached to the panel hole 14 as it is. Therefore, it was necessary to remove the set spring 15 from the device, insert the device through the mounting panel 13, and then reattach the set spring 15 to the device body 11 to secure the device. . In this way, the setting spring 15 must be attached and detached, making the device installation work inconvenient.

[Purpose of the invention] In view of the above-mentioned circumstances, the object of this invention is to provide a panel-mounted device in which the main body of the device can be easily attached without the need to attach and detach the set spring.

[Disclosure of invention]

In order to achieve the above object, this invention is such that the main body of the device is inserted into the hole of the mounting panel, the mounting flange provided on the front surface of the main body of the device abuts the front surface of the mounting panel, and a pair of insertion shaft portions and each shaft are connected to each other. A pair of base parts bent in an L-shape from the bottom and an abutment part provided at the part connecting the two base parts are provided, and each of the insertion shafts is inserted into the insertion hole provided on both side walls of the device main body. The panel-mounted device is configured to be mounted on the mounting panel by a set spring having a rotatably inserted portion abutting the abutment portion against the rear surface of the mounting panel, the device being mounted on both sides of the device main body. A groove for fitting the base of the set spring is provided at a position from the insertion hole in the wall to the rear end, and the set spring is always biased so as to sandwich the main body of the device from both sides, and when flipped backward, the base of the set spring The spring fits into the fitting groove and the width of the spring becomes smaller than the width of the hole in the mounting panel, and when it is flipped forward, its base rides on both sides of the device body and the width of the spring becomes larger than the width of the hole in the mounting panel. The gist is a panel-mounted device characterized by:

This invention will be explained in detail below with reference to drawings showing embodiments thereof.

FIG. 1 shows an embodiment of the panel-mounted device according to the invention, viewed from the side, and FIG. 2 shows it viewed from above. As shown in these figures, this panel-mounted device includes a mounting flange 2 on the front side of a square box-shaped device body 1. The device main body 1 is formed to approximately fit into a rectangular hole 4 formed in a mounting panel 3. Insertion holes 1b, 1b are formed in the left and right side walls 1a of the device main body 1 at the upper and lower intermediate heights, slightly closer to the rear end. Fitting grooves 1c, 1c are formed in the horizontal direction so as to open toward the rear end. The fitting grooves 1c, 1c have a width and depth that corresponds to the set spring 5.
The diameter of the set spring 5 is preferably larger than the gap between the hole 4 of the mounting panel and the device body 1.
The depth should be such that it does not protrude. The set spring 5 is connected to the connecting rod portion 5a and to both ends of the rod portion 5a.
A pair of first plates are bent to form a letter shape.
Side rod portions 5b, 5b, and a second side rod portion 5 formed by bending into an L-shape on the side from each first side rod portion 5b.
c, 5c. The bent portion between the first and second side rod portions 5b and 5c is an abutment portion 5d, and each base end portion of the second side rod portion 5c has a base portion 5e and an insert that is bent at a right angle from the base portion 5e. A shaft portion 5f is provided. The insertion shaft portion 5f is
It is rotatably fitted into the insertion hole 1b through the fitting groove 1c. This set spring 5 is freely reversible back and forth, and as shown in FIGS. 3 to 5,
When inverted backwards, the base portion 5e fits into the fitting groove 1c due to its elasticity, thereby reducing the spring width to fit within the width of the hole 4 of the mounting panel. In this way, the width of the set spring 5 is reduced, and in this state it is passed through the hole 4 of the mounting panel. When the mounting flange 2 hits the front surface of the mounting panel 3, the set spring 5 is rotated upward and forward. As a result, both base portions 5e,
5e comes off from the fitting grooves 1c, 1c and rides on the outer surface of the side wall 1a, expanding the width of the first and second side rod parts 5b, 5c. At this time, as shown in FIGS. 1 and 2, the connecting rod portion 5a rests on the device main body 1, and the abutment portion 5d abuts against the back surface of the mounting panel 3. The device then sets the set spring 5.
It is fixed to the mounting panel 3 by its elastic force.

In this way, since the set spring 5 can be reversed and its width becomes narrower when reversed, the set spring 5 can be inserted into the hole 4 of the mounting panel while the set spring 5 is attached to the device.
By reversing the spring 5 and returning it, the device can be fixed to the mounting panel 3. The work became extremely simple.

Note that the spring is always biased so as to sandwich the device main body from both sides. Further, although the spring was equipped with an insertion shaft bent from the base, there is a risk that the insertion shaft may come off due to vibration, so as shown in FIGS. 6 and 7, A retaining shaft portion 5g bent in a crank shape from the insertion shaft portion 5f may be configured to contact the inner surface of the side wall 1a. Further, the insertion holes 1b can be arranged in two stages, front and rear, and by using either of them, the set spring 5 can be appropriately applied to the mounting panel 3 having a different thickness.
Further, the set spring 5 is designed to come into contact with the device body (in this case, the hour meter) 1 from the bottom, but the insertion hole 1b is located at an intermediate position of the device body 1 (in the vertical direction in FIG. 1 or 6). intermediate position)
If it is formed in this way, it can be installed in an inverted position. Furthermore, the same spring 5
The abutting portion 5d is located above the horizontal line passing through the insertion shaft hole 1b, and is designed to prevent it from coming off due to vibration due to the moment relationship.

[Effect of idea]

As we have seen above, in the panel-mounted device according to this invention, the device body is inserted into the hole in the mounting panel, the mounting flange provided on the front side of the device body comes into contact with the front surface of the mounting panel, and a pair of plug-in A shaft part, a pair of base parts bent from each shaft part to form an L shape, and an abutment part provided at the part connecting the two base parts, and are inserted into insertion holes provided on both side walls of the device body. The panel-mounted device is configured to be mounted on the mounting panel by a set spring into which each of the insertion shaft portions is rotatably inserted, bringing the abutting portion into contact with the back surface of the mounting panel, An insertion groove for the set spring base is provided at a position extending from the insertion hole to the rear end of both side walls of the device body, and the set spring is always biased so as to sandwich the device body from both sides, and is pushed rearward. When it is reversed, its base fits into the fitting groove and the width of the spring becomes smaller than the width of the hole in the mounting panel, and when it is reversed forward, its base rides on both sides of the device body and the width of the spring fits into the hole in the mounting panel. Since the width of the set spring is larger than the width of the set spring, it can be easily and securely fixed to the mounting panel by simply reversing the set spring while it is attached to the device.
