  • Patent number: 4846736
    Abstract: A one piece ignition wire terminal which does not require a separate spring to provide dependable retaining force to a terminal, and which may be used either as a straight ignition wire terminal or a bent ignition wire terminal, is crimped to an ignition cable over only a portion of its crimping area, to increase the retention of the terminal to the cable. The terminal includes a barrel portion with an integral spring formed by cutting a generally U-shaped slot in the material of the terminal, forming a spring tongue portion, which is provided with a radial projection. The radial projection may be directed inwardly, for use with a conventional spark plug-type terminal, or outwardly, for use with a conventional distributor socket.
