The clamp section has an inner surface adapted to grippingly engage a battery post to inhibit angular rotation and includes elongated slots disposed oblique to the central axis of the battery post with opposite edges adapted to penetrate the battery post and a coined pattern extending adjacent and parallel to the slots. The terminal is clamped to the battery post by a nut and bolt assembly with the nut being force fit mounted to the clamp section for good electrical continuity therewith and heat sink characteristics and the bolt having a captured bolt head for positive mechanical opening of the connector.

  • Patent number: 5030106
    Abstract: A clamp for mounting a jumper cable to a terminal of a storage battery. The clamp comprises first and second movably mounted jaws having opposed gripping faces which define a gap for receiving the terminal. At least one of the gripping faces has an electrical conductor portion thereon for establishing electrical contact with the terminal. The first jaw has a gear rack mounted thereto, which is engaged by a pinion gear which is rotatably mounted to the second jaw. A worm wheel is mounted coaxially to the pinion gear, and is engaged by a drive worm. A handwheel is provided for manual rotation of the drive worm. The resulting movement of the first jaw relative to the second jaw adjusts the gap so that the battery terminal can be received and gripped therein. The clamp may have a bore which penetrates into the electrical conductor portion of the jaw for receiving an end of the jumper cable in electrical contact therewith, and a setscrew for securing the end of the jumper cable in the bore.

  • Patent number: 4959031
    Abstract: A battery terminal post clamp is provided and consists of a pair of inwardly curved arms having crossed end portions. The arms are pivotaly connected at their lower ends in a spaced apart relationship on one of two mounting plates. The mounting plates are attached together to fit and grip an electrical conductor of a battery cable. A finger engaging portion having an aperture therethrough is affixed to each crossed end portion of each arm so that a guide bolt can extend through each aperture with a guide nut threaded on the end of the shank. A coil compression spring is arranged on shank of the guide bolt between the finger engaging portions. The spring urges the finger engaging portions apart causing the arms to move towards each other to grip a terminal post until a person squeezes the finger engaging portions together to compress the spring and disengage the arms from the terminal post.

  • Patent number: 4894028
    Abstract: A C-shaped clamp having elongated flanges at its ends defining the open portion of the "C". A bolt is inserted through holes provided in the flanges. A nut tightened on the bolt against one of the flanges compresses the C-shaped clamp. A U-shaped key slideably fitted in a lengthwise slot in the threaded end of the bolt engages the inside wall of one flange and the outwardly facing side of the nut and pulls the flanges apart when the nut is loosened on the bolt thus expanding the C-shaped clamp.

  • Patent number: 4740179
    Abstract: Several embodiments of self-spreading battery terminal connectors utilize restricted movement bolts. In each embodiment, the battery terminal connector bolt is freely rotatable without experiencing threaded axial movement in one side of the connector, with the opposite connector then being movable along the bolt to open or close the connector around a battery terminal.
