TV set assembly system handling printed circuit boards - uses guidance system sliding boards into position inside case

摘要

The guidance system is for a printed circuit board which is mounted inside a housing having two opposite parallel faces. The system has two parts of sensibly the same form and which perform similar functions. The printed circuit board is fixed to these parts which are mounted on the walls of the housing. The two parts enable the printed circuit board to be moved into and out of the housing. Each part is made up of three elements. The first element (26) is a base which is fixed to the lower wall of the housing. This element (26) has a rectangular plate. The underneath part of the plate is flat but has one it transversal ribs and projecting parts which fit into the lower wall (24) of the housing. On the top of the plate is a rectangular location field having two parallel sluts in it. The two sides of the rectangular location piece are aligned at an angle and to the longitudinal edges of the plate.
