Description

[Detailed Description of the Invention] This invention relates to a display device for a small control device such as a socket or a terminal block that is attached to a substantially rectangular rail according to the DIN standard.

The general mounting structure for mounting small control equipment on a substantially square-shaped rail is as shown in Fig. 1, in which a stator 3 and a movable member are engaged with flanges 2 and 2' formed on both sides of the upper part of the rail 1. 4 is provided in the main body 5 of the device.

The movable element 4 is movable in the directions of arrows A and B relative to the main body 5, and is normally pressed in the direction B by a return spring 6. When pulled in the direction A, the tip of the mover 4 separates from the flange 2',
That is, the engagement between the movable member 4 and the flange 2' is released, and the main body 5 and the rail 1 are separated. On the other hand, to attach the main body 5 to the rail 1, pull the mover 4 in the A direction, first fix one of the flanges 2 of the rail with the stator 3, and then return the mover 4 in the B direction. Then, the other flange 2' is fixedly engaged.

In short, in this type of mounting device, the movable element 4
It is attached to and detached from the rail 1 by moving in the AB direction.

By the way, in the case of equipment in which the above-mentioned mounting method is adopted, especially small control equipment such as sockets or terminal blocks, a large number of them are often used closely together on the rail 1. Wiring was facilitated by attaching numbered nameplates to each device. However, depending on the structure of the equipment, there may not be a suitable place to affix the nameplate, and even if it is possible to affix the nameplate, it may not be possible to achieve the intended purpose because it is difficult to see, and the nameplate may peel off after being affixed. There were problems such as the possibility of In addition, it is necessary to provide a fitting hole for attaching the name plate to the main body of the control device, which increases the number of manufacturing steps and makes it impossible to manufacture the device at a low cost.

This invention was developed in view of the above-mentioned points, and it solves the above-mentioned conventional problems by using a movable element for rail attachment and allowing a nameplate to be attached to the movable element.

In summary, this idea consists of forming a part of a mover for mounting a rail that protrudes outward from the side of a small control device, with a marking part on the top surface and a fitting leg part on the bottom side. It is characterized in that the marking stand is removably attached.

Hereinafter, embodiments of this invention will be described with reference to the drawings. Fig. 2 is a plan view of a large number of equipment bodies assembled on a rail, Fig. 3 is a perspective view of the main parts of this invention, Fig. 4 is a front view of a state in which a marking stand is attached to a movable element, FIG. 5 is a front view of a memorization stand according to another embodiment of the present invention in an attached state, and FIG. 6 is a perspective view of the memorization stand. Memorial stand 7 related to this idea
, a rectangular marking part 7a with symbols etc. written on the upper surface and a pair of fitting legs 7b, 7 extending below the square marking part 7a.
b is integrally molded from a resin material, and as shown in FIGS. 3 and 4, the legs 7b, 7b of the marking stand 7 are compressed inwardly against the elasticity of the legs 7b, and as shown in FIGS. The leg portion 7
The end hook portions 7c, 7c of the holes 4b, 7b are fitted in such a way that they engage with the lower ends of the holes 4a.

Note that the marking stand 7 can be easily removed by disengaging the lower end of the hole 4a from the hook portions 7c, 7c. Since the name plate 7 is neatly attached to one side of the device main body 5 as shown in FIG. 2 after being attached, there is no unsightly appearance and there is no fear of incorrect wiring during wiring work. Furthermore, since there is no need to take the trouble to provide a fitting hole for attaching the marking stand in the main body of the device, the number of man-hours required for manufacturing the main body of the device can be reduced and the device can be manufactured at low cost. FIGS. 5 and 6 show another embodiment of this invention, in which a movable member 4' is held from the outside by legs 7b', 7b' of a marking stand 7'.
In addition, 7a' is a memorization part, and 7c' is a hook part.

Since this invention is constructed as described above, it is particularly effective when used in small control equipment and the like where it is difficult to attach a name plate due to the structure.
