Product details

Standard 4-Way Line Plug 431A

Standard BT type 4-way Line Plug using Insulation Piercing Contacts (IPC), with strain relief. To fit the flat line cord to an IPC plug, simply provide a clean cut across the end, and strip off 11 to 12mm of the outer sheath. Allow the wires to separate from one another by approximately 1mm, then push and tease them gently into the plug, which has locating guides built in for each conductor.Once fully home (the coloured wires can be seen through the slot behind the contacts) use heavy duty pliers or a small vice to press all the gold coloured contacts flush with the plug body; push down the small strain relief members immediately behind the contacts, then force down the cable clamp at rear.
