Performance Balance Requirements For Materials Used In Press-fit Terminal Connectors

In designing push in wire terminal block, material selection directly impacts overall performance and product characteristics. push fit terminal block connector comprises conductive components, an insulating shell, and an elastic structure; its internal springs and shell materials must be compatible to meet both mechanical and electrical requirements.

For the conductive components of push connector block, most manufacturers use copper and its alloys as the base material. These metals possess excellent conductivity and corrosion resistance, and can stably handle current transmission over a wide temperature range. The selection of the shell material must also consider both insulation strength and mechanical rigidity. Different plastic resins exhibit significant differences in flame retardancy, thermal stability, and aging resistance; these characteristics determine the physical stability of push wire terminal block under various environmental conditions.
