Pre-Insulated Terminals

Ring Terminal - RT Range

The Legend / CABAC™ range of pre-insulated terminals is comprehensive, and is being developed continually as switchgear, contactors, terminal blocks, etc. evolve. In more recent years terminals have been getting smaller, and we have developed our range of 0.5mm tab thickness quick connectors, increased our range of bootlace pins and introduced the 0.3mm2 range of terminals to name a few developments. Our terminals are high quality 300V terminals having many advanced features for ease of use.

  • High quality product meeting International Standards
  • Long-term electrical integrity
  • A unique funnel entry that speeds wire terminating and increases reliability
  • Translucent nylon in fully insulated quick connectors reduces installation errors
  • Full technical backup including QA
  • Approved by government authorities
  • Conforms to AS 3169 and AS 4437

All terminals should be crimped onto the conductor using a quality crimper that is designed to crimp the specific terminal type. If unsure of the terminal/conductor/crimper combination refer to the technical information following and test the nominal pull out force of the crimped connection. If the conductor does not pull out when the nominal pull out force is applied and held for one minute, this will give a good indication of the integrity of the joint. We offer a vast range of crimpers for various applications and terminal types that are shown in the tooling section.

In general, the wire should protrude 1mm out of the front of the terminal.

Funnel Entry

The funnel entry has been specifically developed to speed up wire terminating, while ensuring maximum reliability of the crimped connection. Only single grip terminals are funnel entry.

  • Speeds insertion of the wire
  • Avoids strands folding back and minimises short-circuit risks
  • Reduces stripping tolerances
  • Speeds and simplifies the operation, reducing errors and rejects
  • Reduces installation time

Standard Entry

Fig. 1

Having stripped the insulation, the wire strands tend to 'spring', resulting in a difficult insertion.

Fig. 2

Not all strands are inserted into the terminal barrel, therefore the wire section is only partially crimped

Funnel Entry

Fig. 3

All of the wire strands are properly funnelled into the terminal barrel.

Fig. 4

The wire section can be fully crimped and is both electrically and mechanically more reliable.
