Why Should The Material Of A Push-button Terminal Connector Have Good Heat Resistance?

The heat resistance of materials affects the stability and physical durability of push connector block under high-temperature conditions, especially in continuous operation or high-load scenarios, where these materials are affected by thermal cycling and heat dissipation from surrounding components.

The interior of a push wire terminal block typically consists of two main categories of materials: a metal spring and an insulating outer shell. The metal parts undergo thermal expansion upon temperature increases. If the material's heat resistance is insufficient, it can easily alter contact elasticity, leading to changes in contact pressure and fluctuations in contact resistance. In contrast, using alloys with higher thermal stability and specially treated metals can reduce the range of dimensional changes, thereby maintaining stable electrical connection characteristics.

The insulating shell material also experiences thermal stress. Thermal effects can cause the plastic to soften or deform, thus affecting insulation performance and structural support. Engineering thermoplastic materials such as polyamide or polycarbonate can maintain good mechanical rigidity and resistance to heat deformation at high temperatures, thus supporting the long-term operation of push in terminal block wire connector without damage.
