Abstract
A current breaker for automotive safety systems has a separating punch and a conductor formed with at least one localized decrease in thickness constituting a weakened separating point severable by the separating punch. This current breaker is made by overmolding the conductor in a plastic-injection mold with an encapsulation by a method having a first step of forming the separating point of the conductor in the plastic-injection mold before or during overmolding and a second step of forming with the mold above and below the conductor in the encapsulation a passage fully exposing the separating point and dimensioned to hold the separating punch.
Claims8
A method of making a current breaker for automotive safety systems having a separating punch, the method comprising the steps of:
- positioning a conductor and two cores in a mold,
- overmolding the conductor and the cores in the mold with an encapsulation while forming with the cores passages extending oppositely away from a central part of the conductor in the encapsulation,
- with the cores in the passages, forming the overmolded conductor in the mold with a localized decrease in thickness constituting a weakened separating point during the overmolding, and
- removing the cores from the passages and then providing in one of the passages a separating punch for severing the conductor at the separating point.
