TE Connectivity – TPA Device: Power Triple Lock Wire-to-Board Headers

TE Connectivity (TE) introduces new wire-to-board headers as part of the Power Triple Lock connector product line, thereby expanding the family of connectors into a growing number of HVAC, automation and control and automotive designs. For assembly reliability, the Power Triple Lock connector offers an optional and unique CPA (Connector Position Assurance) device to help keep the connector fully mated and engaged during shipment, installation and use.

Another optional mechanism is the TPA (Terminal Position Assurance) device which firmly positions the contact into the connector housing. To ease assembly, Power Triple Lock connectors feature rounded edges and an anti-snag design. They also feature a latch that audibly clicks to indicate the header or cap and plug are mated.
