The heart of any good solderless terminal system lies in the crimp system used.
This may sound simple, but to maintain electrical integrity, tensile strength and
insulation properties, a sound crimping technique and system must be used. The first
thing to consider is that a good crimp relies on the wire, the terminal, and the tool.
If any of these items are out of the terminal manufacturer's specs, an unacceptable
crimp may result.
The crimped interface between the wire and the terminal is considered
a high-pressure, permanent connection. Again, each component of the crimp
(wire, terminal and tool) contributes to the integrity and the performance of the connection.
An integrated crimp 'system' helps a given terminal meet the stringent conditions of agency approval and requirements
of UL, CSA and military specifications. Crimping technology is designed to produce numerous cold welds between the wire
and wire barrel that renders a nearly invisible electrical connection. A cold weld site occurs when sufficient pressure
is applied to two small, but distinct, metallic surfaces already in intimate contact. Without sufficient cold weld sites a
condition known as "static heating" prevails. Static heating is a self-perpetuating phenomenon that occurs as follows:
Crimping takes advantage of work hardening the copper wire barrel to hold the wire in place.
Mild heating of the crimp begins to stress-relieve the crimped area. When stresses are relieved,
cold weld sites break. Broken cold weld sites increase the resistance between the wire and wire barrel.
This, in turn, increases the temperature in the crimp area; further stress relieving the crimp. This scenario
continues until the crimp area becomes overheated and may result in melted or burned insulation.

| Crimping can be used in the vast majority of terminal to wire applications. While other methods are considered strong mechanical connections with high-performance electrical properties, crimping provides strength under constant load in tension and severe vibration. Crimp connections tend not to crack or creep under sustained loads. Fatigue is not an issue. Since the mechanical performance of a crimp is robust and sound, the electrical properties are less likely to degrade. In short, static heating is avoided when good crimping practice is followed. |
"Soldering or Solder-Dipping Will Improve The Connection"
Crimps are designed to work without solder or solder-dipped wire. When solder is present in a crimp,
the deformation properties change. When the deformation properties change, metal-flow, cleaning, welding
and residual force also change and compromise the mechanical and electrical properties of the crimp.
With diminished mechanical properties, the connection may not survive normal uses. Furthermore, as electrical
performance diminishes, the perils of static heating arise. Additionally, in some cases, copper wire may become
embrittled or solder wicking may affect the flexure strength of the stranded wire. By soldering a crimped connection,
the process heat may compromise the crimp.
Insulated terminals play an important role in many electrical devices. Their reliability, performance and low cost result from the design relationship between the wire, terminal and tool. This connection integrity makes them suitable for many applications. By getting back to the basics, designers will likely find a suitable insulated terminal that meets their reliability, performance and cost requirements. |
