Abstract

A method includes placing a plastic connector block housing portion into a connector block cavity of a header; placing a coil spring into the connector block housing portion; and connecting a metallic termination member to the coil spring and positioning the metallic termination member to be exposed outside the plastic housing portion.

First claim

The claimed invention is:

1. A method comprising:
providing a plastic connector block housing portion;
placing the plastic connector block housing portion into a connector block cavity of a header;
providing a coil spring;
placing the coil spring into the connector block housing portion;
providing a metallic termination member; and
connecting the metallic termination member to the coil spring and positioning the metallic termination member to be exposed outside the plastic housing portion such that the plastic housing portion includes a planar outer surface with the metallic termination member lying flush against the planar outer surface.

2. The method of claim 1 , wherein connecting the metallic termination member to the coil spring includes positioning the metallic termination member to be non-circumferential around the coil spring.

3. The method of claim 1 , further including overmolding the header with an epoxy.

4. The method of claim 1 , further including coupling the metallic termination member to a feedthrough that extends from a housing to the header.

5. The method of claim 1 , wherein placing the plastic connector block housing portion includes placing the connector block housing portion into the connector block cavity on an open side of the header such that the connector block is side-mounted into the header.

6. The method of claim 1 , wherein placing the coil spring includes the plastic housing portion including a receiver section configured to receive at least a portion of the coil spring.

7. The method of claim 1 , wherein placing the plastic connector block housing portion includes the plastic housing portion being integral to the header within the connector block cavity.

8. The method of claim 1 , wherein placing the plastic connector block housing portion includes the plastic housing portion being a discrete plastic housing body mounted within the connector block cavity.

9. The method of claim 1 , wherein providing a metallic termination member includes providing a flat ribbon connector.

10. The method of claim 1 , wherein providing a metallic termination member includes providing a metallic block including at least a portion configured to receive the coil spring.

11. The method of claim 1 , wherein providing a metallic termination member includes providing a metallic termination member that includes a flat ribbon connector which extends away from the connector block and is connected directly to a feedthrough.
