Abstract

This article describes two devices which are locking, positive action retaining plates used to maintain the proper connector-to-floppy diskette drive assembly engagement. They accommodate the 3.5-inch floppy diskette drive units used in numerous system units and an insulation displacement card edge connector used on the diskette drive. The devices are molded polycarbonate structures with a steel spring hot upset to it. The molded units require no secondary operation when manufactured.

Diskette Drive Retention And Connector Location Devices With Horizontal Or Vertical Clips

       This article describes two devices which are locking,
positive action retaining plates used to maintain the proper
connector-to-floppy diskette drive assembly engagement. They
accommodate the 3.5-inch floppy diskette drive units used in numerous
system units and an insulation displacement card edge connector used
on the diskette drive.  The devices are molded polycarbonate
structures with a steel spring hot upset to it.  The molded units
require no secondary operation when manufactured.

      The connector plate assemblies of this disclosure are installed
in the machine by a simple two-step process which requires no tools
and little time.  Also, they are easily removed.  The cover assembly
of the system unit must be removed prior to service or installation
of the connector plate assemblies but no other parts of the system
unit in any way hinder the access to these assemblies.

      Referring to the drawings, Fig. 1 is a perspective view of a
connector plate assembly with horizontal clips.  Figs. 2 and 3 are
top and side views, respectively, of this connector plate assembly.
A ribbon cable connector A (Fig. 2) is inserted into the connector
plate opening from the rear.  This acts to deflect two clips 1 which
snap back into place when the connector A is properly installed,
allowing only the necessary float in all three axes.  In this manner,
the connector A is supported properly with no additional parts.

      The first step in the installation procedure is to insert tab 2
of the connector plate into a slot provided on floppy frame assembly
B.  The second step is to pivot the connector plate until two small
clips 3 are made to deflect against the inner surface of the floppy
frame assembly B. The clips 3 will snap back to their original shape
when they reach recessed holes provided in the floppy frame assembly.

      A floppy drive assembly C, which consists of a drive unit and a
drive slide, is installed from the front of the system unit.  Guides
4 on the connector plate locate the floppy drive ass...
