Abstract
A method for molding a connector boot over a connector of a wire harness comprises positioning the connector of the wire harness into a mold cavity of a mold. A resin mixture is de-aerated to provide a de-aerated resin mixture including a synthetic resin and a hardener. The de-aerated resin mixture is injected into the mold cavity to gradually fill the mold cavity from bottom to top. The injected de-aerated resin mixture is then allowed to harden to form the connector boot around the connector of the wire harness under isothermal conditions. Once cured, the connector boot is demolded.
Claims15
A method for repairing a damaged connector boot of an impaired wire harness, the method comprising:
- removing the damaged connector boot from the impaired wire harness;
- producing a dummy connector having an outer surface geometry corresponding to that of the damaged connector boot to be replaced;
- molding a silicon shell around the dummy connector;
- demolding the dummy connector;
- positioning the silicon shell in an outer rigid shell, the silicon shell and the outer rigid shell forming a mold used for molding a new connector boot;
- and then
- molding the new connector boot over the connector of the wire harness, wherein molding the new connector boot comprises:
- positioning the connector of the wire harness into a mold cavity of the mold, the mold cavity having a bottom end and a top end;
- degassing a resin mixture to provide a de-aerated resin mixture, the de-aerated resin mixture Including a synthetic resin and a curing agent, the curing agent configured to cure the synthetic resin from a flowable state to a solid state;
- injecting the de-aerated resin mixture into the mold cavity to gradually fill the mold cavity from the bottom end to the top end of the mold cavity;
- allowing the de-aerated resin mixture to harden to form the new connector boot around the connector of the wire harness;
- and
- demolding the new connector boot.
