Sometimes customers are unaware that the same advanced technology used to manufacture QPL AS39029 Crimp Pin & Socket designs can also be used to create custom commercial crimp pins and sockets.
Crimp pins and sockets are valuable to customers requiring a quick and reliable method to crimp attach wires for harness applications. Plugging a male crimp pin into a female crimp socket makes interconnection easy.

The pin side of a crimp pin has a diameter and length compatible to the insertion depth and acceptance range of the mating crimp socket. Typically the crimp barrel has an inspection hole to confirm the wire depth.

Screw machine crimp sockets can have conventional contact clip construction or advanced, early entry reversed contact clip technology. Screw machine sockets feature two piece construction for long-term durability and high performance. The outer shell is high-speed machined using brass alloy, both cost-effective and mechanically strong. The internal multi-finger contact clip is precision stamped beryllium copper, heat-treated for near-steel strength and high conductivity.

Contact clip fingers not only apply retentive mechanical forces onto the mating pin, they score the pin surface to achieve a gas-tight superior electrical connection. Gold plating is used on both outer brass shells and internal contact clips to prevent corrosion and increase durability against wear.

Typically crimp pins and sockets are used in both wire harness as well as in molded contact insulators. One advanced version of a contact clip is called Eagle Grip.
Eagle Grip is a reversed contact clip. Eagle Grip contacts are ideal for early pin engagement. Eagle Grip contact clips are press-fit, not captivated into the brass shell and therefore, do not require a stainless steel hood for clip retention. This results in cost savings. Eagle Grip contacts are available in SIZE 16, 20 and 22 crimp socket receptacles.
Four major advantages of non-QPL custom crimp pins and sockets
1. Multi-finger contact clips provide better power distribution than traditional split crimp pins.
2. Cost savings: In high-wear applications, two piece receptacle construction allows for heavy gold only on clip while applying thinner gold on larger crimp shell.
3. Eagle Grip reversed contact clip technology is ideal for early pin engagement and does not require an additional stainless steel hood. More cost savings.
4. Screw machine crimp pins and sockets are known for their quality and performance.
