Stability

The stability of the IDC terminal depends on the spring characteristics of the terminal head and the load capacity of the wire.

IDC terminals are easier to control from a design point of view.

At the same time, the elimination of external strain capacity can prevent the movement of the cable terminal interface.

For solid wire, through appropriate stress relief, due to the higher inherent mechanical stability, the performance will be better.

Typically, for smaller wires, the terminal is designed to provide pounds of force and several mils of elastic deflection at the interface. For larger wires, the force can be as high as 6.5kg to 9kg.

IDC terminal crimping

Crimping works as well as in this field, because it produces metal contact in the crimping process, and a small amount of elastic performance of the wire is stored due to axial compression.

With the passage of time, if the crimping joint maintains a stable state of mechanical development, the additional diffusion welding technology can pass through the interface.

However, the process of stress relaxation and creep of terminals and wires in the system tends to reduce the structural stability of construction machinery.

Therefore, depending on the design of the mechanical system, the subsequent process may eventually lead to a decline in performance.

Due to vibration and / or reduced stress relaxation edge strength, mechanical instability causes a decrease in the life of the equipment.

Stranded wire

With regard to the stranded wire, the mechanical system stability of the stranded wire harness plays an important role in the performance, and there are two factors that affect the performance.

First, because the strands are under compressed load, due to mechanical interference, stress relaxation and creep, the wire harness in the relaxation time slot tends to reduce the contact force.

The degree of potential relaxation mainly depends on the type of strands used by the enterprise.

The number and stranding of stranded wire, the coating on the top of the conductor and the type of insulation play an important role in mechanical stability.

At the same time, the cables that are easiest to cover usually perform better than solid wires.

Second, because the wire contact only has a limited number of wires between conductivities, and therefore affects the overall conductivity.

If the wire is tinned, the latter can be optimized.

In the case of multiple wires, it is obvious that a well-designed strain relief device is important.

Sometimes additional IDC slots provide the necessary mechanical stability.
