New connector concept improves functionality

The range incorporates an internal, latched locking mechanism on the connector hood, a range of Han-Yellock modules which allow for various configurations, an adaptor frame for use with modules in Harting's Han-Modular series, insulators that can snap into the front or back walls of the housing, and a protected earth (PE) contact in crimp or Quick Lock termination. According to Harting, the features provide increased versatility, multiplied potential for different configurations, simplified handling, a reduced incidence of errors and increased safety. The Han-Yellock interface consists of a housing, a bulkhead mounting on the housing side and a carrier hood with cover on the cable side. The system can be used with a variety of insulators and fingerproof contact inserts, which snap into place. Contact assemblies can be inserted from the mating or termination side, and also offer an option for contact bridging. The modules require only male crimp contacts and no special assembly tools are required. Harting says that the locking facility is a key function, allowing safe connection and disconnection even under harsh industrial conditions. When locked, the connection is resistant to vibration and shock and is protected against accidental opening. The internal locking mechanism operates as the cable and device sides are joined together, and a red ring around the perimeter of the locking pushbutton will be visible if the housing halves do not snap together properly. This ring disappears as soon as the internally protected stainless-steel springs snap into place. The locking function also features an integrated blocking capability, where rotating the button by 90^° makes it impossible to open the connector. The pushbutton can be set back to its visually open position only after the button is turned back 90^°. It is then possible to release the two housing halves by pressing the snap-in button. This feature provides a mechanism for preventing an accidental opening of the connector without the need for additional components.
