AI Technical Summary

Technical Problem

The terminal block material of the existing aircraft system relay box is not strong enough, resulting in a high scrap rate in production, structural damage during installation, and easy loosening of connecting bolts, which affects normal use.

Method used

The connection method adopts a combination of pins and washers, the terminal material is changed to leaded brass, the connecting bolt is changed to a combination of smooth rod and threaded section, and the threaded hole of the connecting lug is changed to a combination of threaded section and smooth hole, which enhances the connection stability and anti-detachment function.

Benefits of technology

This effectively prevents the terminal block surface from cracking, reduces the possibility of resonance, and ensures the normal operating efficiency and connection reliability of the relay box.

Abstract

A reinforced improved aircraft system relay box, including a base, the base is installed with a movable box cover, the base is internally installed with a terminal post, characterized by: the base is installed with a connecting lug, the terminal post is connected with an insulating plate, the insulating plate is installed on the base through a draw pin assembly, the draw pin assembly includes a draw pin body, a draw pin cap is sleeved and installed on the draw pin body, the draw pin body and the draw pin cap are installed between the insulating plate and the base in a penetrating mode, the connecting mode of the terminal post of the relay box is changed into a combination mode of the draw pin and the gasket to avoid the rupture and layering of the surface of the part due to extrusion force, and the connecting hole is intact, the relay box increases the anti-falling function design: the connecting bolt is changed into a combination of a light rod and a threaded section; the threaded hole of the connecting lug is also changed into a combination of a threaded section and a light hole. This design can avoid the loss of the connecting bolt and effectively reduce the possibility of resonance of the relay box in the body, and ensure the normal use efficiency of the relay box.
