AI Technical Summary
Existing signal isolators are prone to sliding under external forces when connected to guide rails, and the installation process is inconvenient, especially when the width of the guide rails is inconsistent, which limits the installation range.
The pusher with a positioning structure engages with the upright plate through static friction. Static friction is achieved through elastic clips and wavy toothed grooves. The spacing of the clip teeth can be adjusted by adjusting the structure to adapt to different guide rail heights. When the guide rail is not needed, a fixing ear is used for fixation.
It achieves stable fixation of the signal isolator on the guide rail, simplifies the installation process, improves installation adaptability, avoids the inconvenience caused by the use of external bolts, and is suitable for operation in confined spaces.
