Waterproof termination for electrical tube heater - has heat resistant insulating body around terminal, pressing against internal seal and crimped by outer tube

摘要

The termination for electrical tube heater, where a heating element is embedded in insulating material (3) within an outer tube (1) and connected to terminals (2), has an insulating body (6) held against the seal (5) under pressure. The end of the outer tube is tapered so as to grip the insulating body against the terminal. The insulating body is made from heat resistant plastic. The seal is made from elastic material. It is also both heat resistant and water resistant, eg made from silicon. ADVANTAGE - Design of termination is suitable for automatic (ie, machine-made) assembly process.
