Abstract

Illustrated in Figs. 1 and 2 is a retainer insert 6 which was designed to pre-locate and retain connectors 1 on a connector block 2. Holes 3 are used in the connector mounting tabs for locating the connectors and fit to the block using two holes: one hole 4 for a self-threading screw to retain the assembly and one hole 5 to align the insert. The insert 6 (see Fig. 2) is a one-piece molded part with a lid 7 attached to a base 8 using a living hinge 9. The base 8 has locating bosses 10 for the connector(s) plus a boss 11 for the mounting screw 12. The mounting screw boss 11 has a tapered hole 13 which allows for self- tapping screws. The lower surface of the base features a tab 14 which acts as a diamond pin to align the insert during assembly.

Retainer Insert for Connector Docking

       Illustrated in Figs. 1 and 2 is a retainer insert 6 which
was designed to pre-locate and retain connectors 1 on a connector
block 2.  Holes 3 are used in the connector mounting tabs for
locating the connectors and fit to the block using two holes: one
hole 4 for a self-threading screw to retain the assembly and one hole
5 to align the insert. The insert 6 (see Fig. 2) is a one-piece
molded part with a lid 7 attached to a base 8 using a living hinge
9. The base 8 has locating bosses 10 for the connector(s) plus a boss
11 for the mounting screw 12.  The mounting screw boss 11 has a
tapered hole 13 which allows for self- tapping screws.  The lower
surface of the base features a tab 14 which acts as a diamond pin to
align the insert during assembly.  A catch 15 on the base allows the
lid to be closed and locked 18 over the connector mounting tabs 16,17
and held in place during assembly.  Inserts can be assembled to the
connectors prior to their assembly to the docking hardware.  With the
inserts snapped on to each end of a pair of connectors, the
connectors and inserts become a subassembly which can then be
attached to the connector block using the two mounting screws.

      The Retainer Insert design provides for:
-  A low cost way of accurately locating components (e.g.,
connectors) to a part on which tolerances cannot be easily controlled
without difficult or expensive manufacturing or assembly processes.
-  One piece which acts as both locator and retainer for the
connectors.
-  Installation of the connectors prior to installing the connectors
to the block.  This eliminates having to hold connectors and mounting
plates in place while driving the mounting screws, thus easing
assembly.
-  Utilizing the mounting hole in the connector mounting tab rather
than surface features of the part f...
