US 6,206,709 B1 · High voltage terminal for an ignition cable

Abstract

There is provided a high voltage terminal for an ignition cable with which it is possible to easily mount and more accurately position a spring member which is accommodated in the terminal to provide a more reliable electrical connection with an ignition plug having a generally columnar terminal, such as an end terminal. A spring member is provided at its opposite ends with portions having a larger diameter than the diameter of the intermediate portion in the longitudinal direction thereof. When the spring member is disposed within a terminal of generally tubular shape, a C-ring member having a pair of projections is clipped onto the terminal to extend within apertures in the terminal. Each projection of the C-ring member projects into the terminal, so that the spring member is held within the terminal under the condition where the large diameter portion at one end of the spring member is fixed in position between a contact piece of the terminal and the projections of the C-ring member which project into the terminal.

Dependent claims

A high voltage terminal for an ignition cable which is fixable to an end of the ignition cable and electrically connectable to a generally columnar terminal, comprising:

a terminal body including a connecting part having a press-fit clamping portion configured to be press-fitted onto an end of the ignition cable and a tubular terminal configured to receive and engage the generally columnar terminal, said tubular terminal including a contact piece projecting inwardly of said connecting part, and a pair of stopping holes, each stopping hole formed on an opposite side of said tubular terminal at a position adjacent said connecting part;
a spring member having at least at one end provided with a large diameter portion having a diameter larger than a diameter of an intermediate portion in a longitudinal direction thereof, said spring member configured to be positioned within said tubular terminal;
and
an elastic C-ring member having a pair of projections on an inner peripheral surface thereof, said projections being engageable with said stopping holes respectively on opposite sides of said tubular terminal, so that when said projections are engaged within said stopping holes, respectively, said projections engage only said large diameter portion of said spring to retain said large diameter portion in position within said tubular terminal and between said contact piece and said projections.
