A severing apparatus for use with a battery cable is provided. The severing apparatus includes a housing that holds an initiator and a severing element. The battery cable is located through a lateral bore formed in the housing. The severing element is disposed on one side of the battery cable. A deformable blocker can be disposed on the opposite side of the battery cable. When it is desired to sever the battery cable and thereby discontinue the supplying of electrical power by the battery, such as when a predetermined vehicle collision occurs, the initiator is triggered and causes the severing element to move. Movement of the severing element removes a severed battery cable segment. Movement of the severing element and the severed battery cable segment is stopped using the blocker when present. The blocker can be part of a shell that surrounds the housing. Alternatively, the blocker can be held in the housing.

1. A battery cable severing apparatus for locating in a vehicle, comprising:a housing having a first end and a second end and adapted to receive portions of the battery cable; an initiator having at least portions disposed in said housing; a severing element having at least portions disposed in said housing, wherein when said initiator is activated, said severing element moves toward said second end; and a blocker that includes end portions of a container, said end portions become deformed end portions using said severing element when said initiator is activated, wherein said blocker is free of portions located outwardly of said deformed end portions after activation of said initiator such that the deformed end portions are visible from an exterior of said apparatus, and in which after activation of said initiator, said blocker deformed end portions remain part of said container and at least some of said blocker deformed end portions and said severing element are spaced from each other by at least some severed parts of the battery cable. 2. An apparatus, as claimed in claim 1, wherein:said housing has a first bore and a second bore, said severing element moves in said first bore and said second bore is adapted to receive the portions of the battery cable. 3. An apparatus, as claimed in claim 2, wherein:said second bore is a lateral bore and at least portions of said severing element are axially aligned with at least portions of said lateral bore after activation of said severing element. 4. An apparatus, as claimed in claim 1, wherein:said blocker is a single part. 5. An apparatus, as claimed in claim 1, wherein:said housing has a longitudinal extent and said container is located outwardly of at least a majority of said longitudinal extent of said housing. 6. An apparatus, as claimed in claim 1, wherein:said deformed end portions of said blocker deform in a direction past said end portions of said container. 7. An apparatus, as claimed in claim 1, wherein:at least said severing element has at least portions that are electrically insulative. 8. An apparatus, as claimed in claim 1, wherein:said initiator includes a molded insert to prevent escape of said initiator from said housing after activation thereof.
