Joint connector for oven, has immobilization unit with tabs, where ratio of inner diameter of connector and exterior diameter of envelope is maintained in predetermined range by tubular core of envelope

摘要

The connector has an immobilization unit with rectangular tabs (52) cut out in central part of the connector. The tabs extend in longitudinal direction and in opposed longitudinal direction with respect to walls in which the tabs are cutout. The ratio of inner diameter of the connector in its rest state and exterior diameter of an envelope (20) is maintained in 0.85 or in 0.90 but below 1 by a tubular core of the envelope. An independent claim is also included for a method of realizing a joint connector for oven.
