The AMP tool insulation dis-
placement connector system.
Note the right angle hood with
self-locking tabs. The tool,
multipin connectors (with gold
plated pins) and latching
hoods are supplied with each
console.
Audio and Control Wiring
All audio and control I/O connections to the A-5000 console are made
through multipin DB-25 connectors located on the bottom of the console.
The Insulation Displacement Connector System
The I/O wiring interface system is based on insulation displacement
technology. A special AMP wiring tool is included with each console; it is
auto-indexing, and allows individual wire connections to be positively made
with a single squeeze of the tool's trigger. The trigger action is ratchet
controlled, and will not release until a full connection is made. Once released,
the multipin connector held in the tool's jaw automatically indexes to the next
connector pin. The technology is such that no stripping, soldering or tinning of
wire ends is required; all that is needed is for the wires destined for the
connector be snub cut and laid out in order (although tubing should be used on
bare drain wires). An empty DB-25 (or in the case of the optional LSR-500
rackmount line switcher, a DB-9) connector is inserted into the tool, indexed
to the first pin, and the wires are inserted one by one into the jaw and the trigger
squeezed. In this way a single multipin connector can be completely wired up
in a minute or two.
In the event of a wiring error, connector pins may easily be removed from
the shell with the wire still attached, and inserted into the correct position.
Observe the side of the connector, with the metal part down. You will see a row
of "Vees"—simply press the top of the vee together with a scribe or other sharp
instrument; this will unlock the pin from the shell, and it can be removed and
inserted into the correct position. Spread the vee apart to lock the pin in the new
position. It should never be necessary to discard a connector due to a wiring
error.
Note that mating hoods for each connector are also supplied with the
console. These have locking screws that hold the connectors securely to the
bottom of the console mainframe.
