Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a structure for mounting equipment such as a relay on a rail.

[Background technology]

A flat U-shaped DIN rail is generally used as a rail for attaching devices such as relays. Examples of such structures for mounting equipment on rails include those shown in FIGS. 3 and 4. A rail 1 is placed on the bottom surface of the main body 2 of a device such as a relay.
At the same time, a groove 3 is provided on one side of the groove 3 to be engaged with a flange 10 on one side edge of the rail 1, and a groove 3 is provided on the other side of the groove along the bottom surface of the main body 2. A slider 5 that is slidable in a direction orthogonal to the main body 2 is provided, and an engaging protrusion 6 that is engaged with a flange 10 on the other side of the rail 1 is provided on the slider 5. By disposing a spring 8 between the main body 2 and the slider 5 that urges the body 2 toward the rail 1 side, the main body 2 is moved toward the rail 1 side while the engaging protrusion 4 is engaged with the rail 1. Since the lower surface of the engagement protrusion 6 of the slider 5 is a slope, the slider 5 once retreats due to contact with the flange 10, and then engages with the flange 10 under the bias of the spring 8. The protrusion 6 is adapted to engage, and the rail 1 of the main body 2 can be attached with one touch. However, although this device can be easily attached with one touch, it takes time and effort to remove the main body 2 from the rail 1. That is, when removing the slider 5, insert the tip of a tool such as a screwdriver into the hole 9 provided at the other end protruding from the side surface of the main body 2, and pull the slider 5 outward to engage it. In addition to disengaging the mating protrusion 6 from the flange 10 of the rail 1, it is necessary to raise the main body 2 from the rail 1 while maintaining this state. In cases where two or more sliders 5 are provided, the removal work is extremely difficult.

[Purpose of invention]

The present invention was devised in view of these points, and its purpose is to provide a structure for mounting equipment on a rail, which allows for easy installation and removal of the main body from the rail. be.

[Disclosure of invention]

Therefore, in the present invention, a groove into which the rail fits is provided on the bottom of the main body of the device, and a slider that is slidable in a direction perpendicular to the groove is provided on the bottom of the main body, and the rail is attached to one side of the groove and the tip of the slider. is provided with engaging protrusions that engage flanges on both sides of the rail, and is provided with a spring that biases the slider in the direction of engagement with the rail. The device is characterized by having an engaging portion that engages with the slider to hold the engaging protrusion of the slider in a non-engaging position with the rail. The engagement protrusion and the flange of the rail can be kept in a disengaged state.

The present invention will be described in detail below based on the embodiment shown in FIGS. 1 and 2. The basic configuration is the same as the conventional example, and the rail 1 fits into the lower surface of the main body 2 of a device such as a relay. In addition to providing the groove 3, the groove 3
An engaging protrusion 4 that is engaged with a flange 10 on one edge of the rail 1 is provided on one side, and a slider that is slidable along the bottom surface of the main body 2 in a direction perpendicular to the groove 3 is provided on the other side of the groove 3. 5, the slider 5 is provided with an engaging protrusion 6 that is engaged with the flange 10 on the other side edge of the rail 1, and the slider 5 is biased toward the rail 1 with respect to the main body 2. A spring 8 is disposed between the main body 2 and the slider 5. In addition to the notch 11 for arranging the spring 8, the slider 5 here is also integrally provided with an elastic hook 7. When the slider 5 is pulled out, the hook 7 elastically engages with the outer surface of the main body 2 to maintain the slider 5 in the pulled-out state against the bias of the spring 8. .

When the main body 2 is pressed toward the rail 1 with the engaging protrusion 4 engaged with the rail 1, since the lower surface of the engaging protrusion 6 of the slider 5 is a slope, the flange 10 After the slider 5 retreats due to contact with the slider 5, the engaging protrusion 6 of the slider 5, which returns under the force of the spring 8, engages with the flange 10, so that the main body 2 can be attached to the rail 1 with one touch. When the slider 5 is pulled out by inserting a tool such as a screwdriver into the hole 9 at one end, the hook 7 engages with the outer surface of the main body 2, and the slider 5 is pulled out. That is, the engagement protrusion 6 and the flange 1 of the rail 1
Since it is held in a state where it is disengaged from 0,
After that, the main body 2 can be removed without touching the slider 5 by simply lifting the main body 2. When attaching the main body 2 to the rail 1, the hook 7 is engaged with the main body 2 as described above, and after attaching to the rail 1 in this state, the hook 7 and the main body 2 are engaged. Alternatively, the engaging protrusion 6 of the slider 5 may be engaged with the rail 1 by removing the engaging projection 6 of the slider 5.

[Effect of idea]

As described above, in the present invention, the main body can be easily attached to the rail, and the slider engages with the main body against the spring force, and the engaging protrusion of the slider is moved to the non-engaging position with the rail. Since the main body is provided with an engaging part to hold it, it is easy to remove the main body from the rail. Especially when the main body is large and has two or more sliders, it is easy to remove the main body from the rail. The removal work is much easier than in the past.
