Power electronics places stringent demands on connection technology: PCBs must be quickly and reliably connected to Han? industrial connectors. This process is flexible, convenient, simple and possible without additional components thanks to Han-Fast? Lock.

Numerous sectors place strict requirements on power electronics: Compact and highly efficiently solutions are called for in markets such as renewable energy, transportation, robots and automation, where applications are characterized by rough environments and therefore high protection classes. Here, the Han? connector offers ideal characteristics on the housing side.

In principle, the requirements on the housing itself are known; solutions have been developed here and have proven themselves in the field. Power electronics itself must satisfy tougher requirements, however: In short, the electricity must make its way from the Han connector to the PCB. The Harting Technology Group has found the perfect solution in this regard: With the Han-Fast? Lock, the Han connector connects to the PCB easily, quickly and economically.

Inside Look

The Han-Fast Lock satisfies the requirements of high currents paired with simple handling and efficient size, without it being necessary to add additional components to the PCB.

This translates as distinct advantages in application design, during assembly and during servicing. Flexibility and simple handling for service and maintenance are therefore also two of the central requirements on products in power electronics, while no impairment of the connection's performance and reliability is allowed. This is necessary in order to optimise the total costs for PCB production and minimize the device costs (Total Cost of Ownership). The prefabricated connector unit consisting of the Han connector and Han-Fast Lock PCB termination allows simple and error-free assembly.

PCBs are easy to create with the Han-Fast Lock. There is no secret to bringing currents of up to 60 A on to the PCB. But only the Han-Fast Lock makes it possible to set up compact, flexible and simple contacting. Only one contact point is needed for the connection. The printed conductors are through plated and given a bore hole and support point. No further preparations are required. This makes it possible to deal with the technical requirements and thermal management without positioning costly extra components.

Simple Processing

Processing the Han-Fast Lock connection element is simple. A hand crimping tool can be used for small lot sizes, while larger lot sizes can be processed with fully automatic machines. The Han-Fast Lock connection element is delivered on a coil, making it possible to add the stranded wire quickly and automatically. Device manufacturers can enlist prefabricated systems.

Stranded wires up to 10 mm? can be used with the Han-Fast Lock connection element. The contacting on the PCB is just as simple as the fabrication. The assembled contact is inserted into the prepared PCB.

The locking is a part of the Han-Fast Lock. The provided pin is pressed against the PCB for locking. The function is as easy as can be and is comparable to a commercially available push button.
