Wear-resistant case

Technical Field

The invention relates to the field of electronic mechanical structures, in particular to a wear-resistant case.

Background

In the debugging, installation, use, maintenance processes of electronic equipment, the action of dismouting often appears, for example: the chassis needs to slide on the guide rails of the mounting frame; the modules in the chassis need to be plugged into and pulled out of the internal guide grooves. These movements require relative movements on specific guide rails and, because of their weight, are relative frictional movements of the load, which cause wear problems between the chassis and the frame guide rails and between the modules and the chassis guide channels.

In electronic equipment such as radars, communication and the like, protective coating or chemical conversion coating treatment is generally carried out on the outer surface of the equipment, so that the corrosion protection requirement of products is met. In the relative sliding process of the equipment, after the protective coating and the protective coating and the chemical conversion film are rubbed for many times, the coating and the chemical conversion film are easy to damage, and the protective performance and the appearance quality of the product are reduced.

When the chassis enters the track, the upper edge and the lower edge of the chassis can be in contact with the upper track and the lower track of the rack, and then the whole chassis is pushed into the track. After the guide rail is scratched, the surface of the guide rail is damaged to influence the appearance quality, and the scratched part has uneven surface, so that when a subsequent case moves relatively on the surface of the case, the movement resistance of the contact surface of the case and the guide rail is increased, and the abrasion of the case and the plug-in box is increased, which is one of the main factors causing the abrasion of the case and the guide rail.
