Popularization of Science|Understanding Connectors: Board-in Connectors

I. About the Board-in connectors:

The Board-in Connector is an in-line connector that allows multiple terminals to be mounted directly to a printed circuit board (PCB) for simple and permanent connections. Board-in Connectors are now mainstream vertical and right-angle two modes more convenient to save space, providing designers with more choices. It offers a wide range of spacing options, mating configurations, and circuit sizes for greater reliability than hand soldering.

II. The relative advantages of Board-in connectors:

  • One-piece, direct solder-to-board assembly saves space and cost and is easy to assemble compared to two-piece models
  • Terminal and housing locking features ensure secure terminal retention force
  • Board-in Connectors are available in right angle and straight housing options:
    1. Protective terminals for use as wire alignment and fixtures prior to and during the welding process
    2. Stress relief after welding
  • Standard through-hole welding method for more reliable welds than uneven and labor-intensive manual welds
  • Board-in Connectors are available in 1.25mm, 2.0mm, 2.5mm and 4mm pitch sizes, configurations and circuit sizes for greater design flexibility

III. Recommendations for Board-in connectors:

When choosing a connection type, designers often need to consider factors such as cost, assembly requirements, and whether or not the connection needs to be disassembled. In cases where a simple connection will suffice, Board-in connectors are becoming the choice of more designers than hand-soldering other connectors.

Board-in Connector fulfill the requirement for cost-effective and easy-to-assemble connections without disassembly of at least one end. Compared to other in-board connectors, KONNRA connectors offer the widest range of pitch options, mating configurations, and circuit sizes that customers can choose from to meet their needs.

IV. The application of Board-in connectors:

Compared with other connectors, Board-in connectors can better protect the retention of terminals, and are more suitable for medical, lighting, automotive, refrigerator and factory equipment and other industry sectors that require high retention.
