Connector Locks—Avoid Abrupt Disconnects by Locking up Your Connectors

Interpower^® connector locks are designed to prevent accidental abrupt disconnects at the inlet/connector interface. Abrupt disconnects can bend or break blades and pins and can ruin the contacts inside inlets.

Interpower connector locks prevent abrupt disconnects using one of two locking styles: screw-mounted locks, or tool-free connector locks. While the screw-mounted locks are the most secure way to anchor connectors to an inlet, the tool-free option saves a step: you don’t have a top clamping screw like the screw-mounted lock; with the tool-free lock, tension from the hinged steel becomes the clamping force.

How the Screw-mounted Locks Work

Slip the connector lock under the mounting screw heads and leave the mounting screws loose.

Seat the connector. Insert the cord set through the connector lock and into the inlet. Be sure it is seated completely into the inlet since a partially mated connector could cause arcing.

Tighten the locking screw on the connector lock. Tighten the top screw on the lock so that it clamps tight to the connector (cord set).

Tighten the two mounting screws on the sides of the inlet. The connector lock is now secured on the connector and chassis. To remove the cord set, reverse steps 3 through 1.

How to Install Tool-free Connector Locks

Each tool-free connector lock is designed for the outer molding of a specific connector style such as the IEC 60320 C13 and C19 connectors. Interpower offers connector locks for use with the Sheet E and Sheet I plug connectors as well. 

Installation:

1. Remove the two mounting screws of the inlet or outlet.

2. Place connector lock on inlet, aligning the mounting holes with the thumb tab pointing away from mounting surface.

3. Reinstall mounting screws through the connector lock and inlet holes, and fasten to component.

Note on angled connectors: Make sure the top end of the connector (cord set) faces toward the open-angle end of the lock—do not assemble the top end of the connector toward the hinged side of the lock where it its screwed in.
