Abstract
A method and apparatus for producing plastic parts with a resilient projection, such as connectors for corrugated tubing. The method comprises the steps of flowing plastic material on a core provided with a recess to mould the resilient projection, camming the resilient projection out of the recess, after the mass of plastic material is solidified and extracting the solidified part from the core. The invention also extends to a novel connector for corrugated tubing.
Claims8
A connector for connecting a section of corrugated conduit to another component, the corrugated conduit being of the type having longitudinally spaced-apart circular rib members, said connector being of the type molded about a core member and comprising:
- a generally cylindrical body-portion having an extremity defining a conduit entry end;
- a resilient finger mounted to said body-portion, said resilient finger including a locking tongue extending radially with respect to said body-portion for engagement with a rib member of said section of corrugated conduit;
- a first camming surface on said tongue to communicate a yielding motion to said resilient finger as a result of a sliding contact between said tongue and said rib member moving in a first direction during insertion of said corrugated conduit into said conduit entry end;
- a second camming surface on said tongue to communicate a yielding motion to said resilient finger as a result of a sliding contact between said tongue and a member moving in a second direction;
- and
- at least one locking surface on said tongue engaging said rib member and locking said section of corrugated conduit to said body-portion.

- and
- a second camming surface on said tongue to communicate a yielding motion to said resilient finger as a result of a sliding contact between said tongue and a member moving in a rotational direction.
