Rail mounting structure for electrical equipment

Abstract

Provided is a track mounting structure for an electrical device that does not require tools when the electrical device is detached from a track. The track mounting structure for an electrical device includes: a first engaging portion (11a), (11b) that engages with one first track portion (2a) in the width direction of a track (2); a second engaging portion (12a), (12b) that engages with the other second track portion (2b) in the width direction of the track (2); a spring member (20) disposed on the front side with respect to the first engaging portion (11a), (11b); and a slider (30) disposed so as to be slidable in the front-rear direction on the bottom surface of a slider housing recess (14), and is forced in the rearward direction by the force of the spring member (20). The slider (30) abuts against the first track portion (2a) when the electrical device (1) is mounted to the track (2), and the force of the spring member (20) is applied to the first track portion (2a), and the second engaging portion (12a), (12b) is brought into a state in which it pushes against the second track portion (2b).

Claims

1. A track-mounting structure for electrical equipment, wherein the electrical equipment is mounted across a track, the track-mounting structure for electrical equipment being characterized by comprising: The first engaging part is provided on the front side of the bottom surface of the housing of the electrical equipment, which extends in the same left-right direction as the length direction of the rail and in the same front-back direction as the width direction of the rail, and engages with a first rail part (2a) in the width direction of the rail when the electrical equipment is installed on the rail. The second engaging part is provided on the rear side of the bottom surface of the housing and is opposite to the first engaging part. When the electrical equipment is installed on the rail, it engages with another second rail part (2b) in the width direction of the rail. A spring component, wherein the first engaging portion is disposed on the front side relative to the bottom surface of the housing; and A slider, configured to slide in the front-rear direction on the bottom surface of a slider receiving recess formed on the bottom surface of the housing, is subjected to a rearward force by the spring component. When the electrical equipment is installed on the track, the sliding member abuts against the first track portion of the track, causing the force of the spring component to act on the first track portion of the track, thus putting the second engaging portion into a state of pushing against the second track portion of the track. A stop is formed on the bottom surface of the sliding member receiving recess to restrict the rearward movement of the sliding member. The sliding member is provided with an anti-displacement part, which prevents the electrical equipment from shifting its position along the length of the track when it is installed on the track.

2. The track mounting structure for electrical equipment as described in claim 1, characterized in that: The spring component is a leaf spring, which is formed to extend in the same length direction as the track, and both ends of the leaf spring in the length direction are supported by a pair of leaf spring support portions disposed on the front side of the bottom surface of the housing relative to the first engaging portion. The slider is installed between the two ends of the leaf spring that constitutes the spring component along its length.

3. The track mounting structure for electrical equipment as described in claim 1, characterized in that: The spring component is a compression spring disposed in the spring component receiving recess formed on the bottom surface of the sliding member receiving recess. The sliding member includes a wall portion and a receiving recess. The wall portion is erected from the bottom surface of the receiving recess and from the front edge of the receiving recess of the spring member. The receiving recess houses a compression spring disposed within the receiving recess of the spring member. The compression spring constituting the spring component is disposed in the receiving recess of the spring component such that its front end abuts against the wall portion and its rear end abuts against the rear wall portion of the receiving recess of the sliding member.

4. The track mounting structure for electrical equipment as described in claim 3, characterized in that: Multiple compression springs constituting the spring component are arranged side by side in the left-right direction.

5. The rail mounting structure for electrical equipment as described in claim 3 or 4, characterized in that: The free length of the compression spring constituting the spring component is less than 4 times the mean diameter.
