Abstract
A speedometer cable for a vehicle driven from the vehicle transmission has a speed transducer incorporated in the end fitting which attaches to the transmission housing. The speed transducer comprises, for example, a reed switch driven by a permanent magnet which rotates with the speedometer cable core for opening and closing at a rate dependent on the speed of rotation. The transducer has one terminal grounded through the end fitting to the transmission housing and another lead electrically connected to the reinforcing wire of the speedometer cable. A terminal member with an insulation piercing clip is spaced at a position remote from the end fitting and makes contact with the reinforcing wire to provide an electrical connection between the remote terminal and the reed switch to allow transmission of an electrical speed signal from the reed switch to the remote terminal.
