Abstract

Auto-docking electrical connectors, and their interconnections, are inaccessible in most electro-mechanical systems. Disclosed is a means of making such electrical connections accessible for ease of replacement. In systems with redundant connectors one such connector can be changed without disturbing another permitting true concurrent maintenance. Contact pads on pluggable subsystem wipe against the springs in a mounting bay of a larger electronic system.

Serviceable Auto-Connector System

      Auto-docking electrical connectors, and their interconnections,
are inaccessible in most electro-mechanical systems.  Disclosed is a
means of making such electrical connections accessible for ease of
replacement.  In systems with redundant connectors one such connector
can be changed without disturbing another permitting true concurrent
maintenance.  Contact pads on pluggable subsystem wipe against the
springs in a mounting bay of a larger electronic system.

      An electronic sub-assembly, which fits into a larger system,
can be autoplugged using a number of common connectors.  Each of
these connectors is designed to fit on the rear of the subassembly
and to mate into a socket within the larger system.  Because of its
position the socket and cable are difficult to service and impossible
to change while the sub-assembly is in position.

      Fig. 1 shows an auto-docking scheme in which both the
connectors and the wiring are mounted at the front of the assembly.
In this example the contact pads (1) are shown on the pluggable
sub-assembly (2) whilst the mating springs (3) are on the larger
electronic system (4).  A single row of contacts is illustrated in
this example.

      The springs (1) in this pluggable sub-system (2) are designed
so that they may slide either forwards or backwards on the pads (5).
The converse is equally true and the half of the connector which is
mounted in the larger system (4) can be removed without removing the
sub-assembly.  Contact is made automatically when the sub-assembly
(2) is inserted.  Pads (5) holding mating springs (3) is a contact
block assembly designed to snap in place at each side of system
compartment (4).  Contacts (3) are bonded to a base which has
protective guidance ribs (9) to align with the mating connector (10).
Compressive compliance (8) ensures positive interference of each set
of contacts.  Shearing compliance (7) ensures alignment of contacts
when the...
