Crimping Technology for Industrial Connectors 101


How do you achieve the best-possible crimping in accordance with the industry safety standards?

The quality of an electrical connection depends to a great extent on the choice of suitable components in the respective nominal section widths and using recommended tools for processing.
Size differences between the cable and the connector (pipe-type cable lug/multicore cable end) are the result when only one crimp contact lead in class 5 und 6 - even with different structure (bunched conductor, stranded or compressed strand) could be compressed. Despite what appear visually to the sleeves, the correct combination of conductor, contact and tool can provide "gas-tight" crimping. The dimensional stability on the above-mentioned connecting points is guaranteed by, among other things, the following standards: 

• DIN EN 60228 (VDE 0295), September 2005 "Conductors for cables and insulated lines"
The content of the standard includes among other things the maximum wire diameter and the maximum conductor resistance for the respective nominal cross sections (mm²), but not however, the number of wires or the structure. Improved technologies in the area of copper production mean that the conductor resistance specified in the standard can now be achieved with reduced cross sections. 

• DIN 46228 – 4, September 1990 "Multicore cable ends – tube-type with plastic sleeve" 

• Quality of crimping as per DIN 46228 – 1 and DIN EN 50027

 
Should connectors be crimped or soldered together? 

The crimp connection is the best type of connection for all loaded applications. The advantage compared against all other connection contact cables is - 100% process-consistent fabrication and quality control in accordance with safety standards. Full compliance to safety standards will guarantee tensile strength, current load and forward resistance.

Solder connection on the other hand whether "soldered by hand" or automatically soldered" can affect the overall quality of the soldering points based on:

- the experience of the person doing the soldering
- temperature changes and movement, as the soldering point can deteriorate as time passes (problems that occur with the electronics/electrical system are often down to "dry solder joints" - in other words, poor contact)
