    This connector guide illustrates the relationships and trade-offs involved in selecting and using connectors, providing the fundamental knowledge for understanding their properties and electrical specifications. It explains basic principles, material selection during manufacturing, physical characteristics, processing techniques, and the resulting implications for function and application. The fourteen chapters cover:

    • What is a connector?
    • Connector components
    • Connection techniques
    • Insulator materials
    • Contact materials
    • Contact surfaces
    • Contact resistance
    • Shielding measures
    • Connector locking mechanisms
    • Housings and mechanics
    • Power electronics
    • High data rates
    • Further processing in the manufacturing process
    • Connector selection.

    The chapters detail the differences and present the advantages and disadvantages of individual materials, manufacturing processes, and application methods, weighing them against each other and evaluating them. Both operating limits (current load at higher ambient temperatures) and behavior at the highest data rates are addressed. This connector guide is not intended as a purchasing aid, but rather as a compendium of the diverse properties, designs, and processing options. It shows, independently of manufacturers, which alternatives are available and what the consequences of choosing certain features are, for better or for worse.

Seminar 6: Surface coating of contact materials

 NN| NN

What you will learn:

  • Surface texture and geometric requirements of the base material
  • Advantages and disadvantages of the coating metals used
  • Differences between strip and individual electroplating
  • >> Learn more

    This seminar covers the theoretical foundations and principles of electroplating. Influences on deposition and a general process sequence for coating parts complement the theoretical framework. Many prerequisites regarding the base material, product design, and material selection must be met to achieve coating quality. These are discussed in detail, and in addition to the surface finish and geometric requirements of the base material, the interaction between the base and coating materials is also explained. The functional significance, advantages, and disadvantages of coating metals used in connector and electrical engineering, as well as current trends, are explored. Techniques for single-part electroplating, such as barrel, vibrobot, and rack plating, are presented using videos, and the possibilities of coating are illustrated with product examples. Selective plating of individual parts completes the portfolio of bulk material coating. The differences and advantages of strip plating compared to single-part plating then form the transition to strip plating. This section delves further into the specific process flow of coil plating and explains the various methods, such as immersion, brush, strip, and spot plating, using films and different selective tools. Additionally, the process-related tolerances and specifications of the various techniques are discussed, as well as the dimensional limitations of coil plating technology. Practical experience and product examples support the presentation.

After the presentation, attendees will be able to select the material that best meets their specific requirements from the wide range of available plastic types.

Seminar 8: The connector as a key factor in interference immunity

Dr. Heinz Zenkner

 Dr. Heinz Zenkner | Publicly appointed and sworn expert for EMC

What you will learn:

  • Sources of high-frequency interference
  • Measures along the transmission path up to the interface
  • Development of pre-compliance measurement for interference emission from interfaces
  • >> Learn more

    As electronics become increasingly complex and interconnected, electromagnetic compatibility (EMC) management is crucial to prevent electromagnetic interference (EMI) that can degrade performance or cause malfunctions. Modern EMC measures encompass not only EMC control in high-speed circuits and power electronics but also interface optimization. Key strategies include effective filter design with transient protection, optimized grounding and contacting to minimize impedances, and consideration of the EMC behavior of interface cables. This seminar demonstrates how high-frequency interference originates and how it can be reduced at the source. Furthermore, measures along the transmission path up to the interface are presented. Here, filter circuits with inductors, capacitors, and surge-limiting components play a central role. Layout design is presented, taking into account impedance matching and signal propagation. Filter components are briefly explained, and parasitic impedances and effects that influence filter functionality are discussed. Further applications demonstrate filter topologies, grounding concepts, and the selection of suitable components. Next, grounding concepts that significantly influence EMC functionality are presented. This includes a discussion of housing shielding attenuation, connector contacting, and cable shielding attenuation, with key aspects explained. The final section describes the setup of pre-compliance measurements for interference emissions from interfaces. Early testing allows for the optimization of the EMC design of device interfaces, ensuring compliance with legal and performance requirements—a crucial factor in the development of modern electronic products.
