The Tinel-Lock family of adapters is available to fit most popular mil-circular connectors, and some rectangular connectors, with straight or angled geometries. Taking steps for greater reliability within high-performance ruggedized harnesses by attachment of over-braids to the connector backshell adapters, Tyco Electronics offers the Tinel-Lock ring. This ring is a shape memory alloy, which when heated, shrinks in diameter to apply great forces, thus locking the ring onto the braid and adapter resulting in a secure low-resistance termination. Rings are sized to fit the corresponding adapter and accommodate either single (“AI” part number suffix) or double (“BI” part number suffix) braids.
