Abstract

An eccentric bushing is used to align the holes on an equipment panel with the holes in a support rack. The hole pattern in the rack is designed to the EIA (Electronic Industry Association) Standard RS 310. The EIA standard RS 310 defines both standard panel height and hole patterns for devices used in wiring closets to support telecommunication equipment. Fig. 1 shows a partial schematic of the device which includes a mounting rack 10 and a plurality of panels 12. Each mounting rack is fabricated with mounting holes such as 14 and 16. A plurality of fasteners (not shown) are used to connect the panel to the mounting rack. The holes in both the rack and panel are spaced in accordance with the EIA standard RS 310 which specifies spacing for a 1.75-inch panel height and a 3.50-inch panel height.

Panel Mount Plastic Bushing

An eccentric bushing is used to align the holes on an equipment panel with the holes in a support rack. The hole pattern in the rack is designed to the EIA (Electronic Industry Association) Standard RS 310. The EIA standard RS 310 defines both standard panel height and hole patterns for devices used in wiring closets to support telecommunication equipment. Fig. 1 shows a partial schematic of the device which includes a mounting rack 10 and a plurality of panels 12. Each mounting rack is fabricated with mounting holes such as 14 and
16. A plurality of fasteners (not shown) are used to connect the panel to the mounting rack. The holes in both the rack and panel are spaced in accordance with the EIA standard RS 310 which specifies spacing for a 1.75-inch panel height and a 3.50-inch panel height. A bushing 18 with an elongated slot (Fig. 2) is rotatably mounted onto the panel. By rotating the bushing 180OE (Fig. 1) a single hole on the equipment support panel is made to align with one of two holes on the rack. Thus, a non-standard sized panel of 2.62 inch height is made to mount onto a rack with a standard hole pattern. Fig. 2 shows the plastic bushing displaced from the mounting holes. The design is a snap-together type and is fitted into the hole without a tool. The curved fingers 20 ride on the back surface of the panel and insure that the bushing is firmly connected to the panel.
