Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to equipment for mounting rails on distribution boards and the like.

[Background technology]

In distribution boards, etc., rails are laid on the main body, and devices such as electromagnetic contactors are attached to the rails. By the way, when trying to connect, for example, a thermal relay to a device that is attached to this rail, conventionally a metal plate fixed to the thermal relay with screws or the like was attached to the electromagnetic contactor, which had the following drawbacks. . That is, it is not possible to remove two devices from the rail while the two devices are still connected. Furthermore, it is not easy to connect two devices.

[Purpose of the invention]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a rail mounting device that allows two devices to be easily attached and detached from the rail at the same time while both devices are connected.

[Disclosure of the invention]

This invention provides a transaction engagement in which a pair of hook pieces are formed on the bottom of the first device to be hooked to the collar of the rail, one of the hook pieces is given elasticity for expansion, and the hook piece is formed with elasticity. A recess is opened on the outer surface of the first device, a connector is provided at the lower end of the second device to be hooked to the detachable engagement recess, and the upper end is rotatably connected to the first device. It is. In this way, the first device and the second device can be easily attached and detached because one of them is hooked, and by pulling the second device while the two devices are connected, it can be easily attached to the rail. Can be installed and removed.

An embodiment of the invention is shown in FIGS. 1 to 5. That is, 1 is a rail, 2 is an electromagnetic contactor, and 3 is a protection relay. On both sides of the bottom surface 2a of the electromagnetic contactor 2, ribs 4 are provided at intervals of the rail width, and one rib 4 has a The hook piece 5 is protruded and a hook recess 6 is entirely formed between the hook piece 5 and the bottom surface 2a.

A notch 7 is formed in the center of the other rib 4, and two elastic legs 8 are integrally suspended from the bottom of the notch 7, and a hook 9 is integrally connected to the elastic leg 8. 9 and electromagnetic contactor 2
A hooking recess 10 is formed between the hooking piece 9 and the bottom surface 2a, and a removal hole 11 is formed in the center of the hooking piece 9. Furthermore, a tapered groove 12 is formed from the notch 7 to the outer surface of the electromagnetic contact M2, into which a screwdriver or the like can be inserted into the removal hole 11. In addition, 13 is a terminal, 14 is an operation button, and 15 is a mounting hole for mounting other than the rail 1. When installing this electromagnetic contactor 2 on the rail 1, insert a jig such as a driver into the tapered groove 1.
2 into the removal hole 11, and the elastic leg 8 is elastically deformed so that the hook piece 9 opens from the bottom surface 23.
/1 collar 16 (c hook recess 6, 1Ot).When removing, do the same operation.

The thermal relay, which is the protective relay 3, has a receiving terminal 17 protruding from the side of the upper end, a protrusion 18 for preventing displacement from the lower end, a notch 19 at the corner of the lower end, and a mounting recess in the center of the notch 19. 20 is formed. In addition, 21 is a terminal,
22 is a reset button, 23 is an operation indicator light, 24 is a set value adjustment knob, and 25 is a mounting hole.

When installing this thermal relay (3) to the electromagnetic contactor 2, insert the long piece 27 of the approximately Z-shaped fitting 26 into the installation recess 20 of the thermal relay (3), and use the short piece 28 for removing the hook piece 9. Hook it into the hole 11, and at the same time attach the protrusion 18 to the mounting hole 1.
151 &, insert the receiving terminal 17 into the terminal 13 of the electromagnetic contactor 2, and connect it electrically and mechanically by tightening the terminal screw to form an integral unit. In this case, the receiving terminal 17 is relatively flexible, and this connecting part can be rotated within a small range. Magnetic contactor 2f with magnetic contactor 2 and thermal relay (3) integrated:
When attaching to the rail 1, first hook the hooking recess 6 to the collar 16, and insert the thermal relay (3) by applying force to rotate it as shown by the arrow in FIG. At this time, the thermal link (3) uses the upper end as a fulcrum and the lower end rotates in the direction away from the electromagnetic contactor 2, so the connecting tool 26 pulls the hook 9 in the direction of the arrow to attach or detach it to the rail 1. enable.

With this configuration, two devices can be easily attached to and removed from the rail 1 while being connected, and since one is hooked, it is also easy to attach and detach the devices from each other.

Note that this rail mounting device can also be applied to construct a reversible switch by connecting electromagnetic contactors.

〔Effect of the invention〕

As described above, according to the rail mounting device of the present invention,
This has the effect that two devices can be easily attached to and removed from the rail while being attached, and the devices can also be easily attached and detached from each other.

becomes easier. When the two separated devices are integrated, the mounting surfaces are flush as shown in the figure, so mounting on a flat surface other than the rail is also possible. ” he corrected. -126-.
