This invention relates to a quick release clamp for applying the laterally constrictable ears of a cable connector to the terminal of an electric storage battery. The clamp includes a bolt having a threaded shank terminating at one end in an enlarged head. The shank is dimensioned to extend through aligned holes in the connector ears, with the bolt head being located on the outermost side of one of the ears. A nut is threaded onto the bolt shank on the outermost side of the other of the connector ears. A cam lever is rotatably connected to the bolt, and is adjustable between a closed position cooperating with the bolt and nut to laterally urge the connector ears together to grip the battery terminal therebetween, and an open position permitting the connector ears to move away from each other to an extent sufficient to permit the cable connector to be removed from the terminal.

1. Field of the Invention
This invention relates generally to cable connectors for electrical storage batteries, and more particularly to clamps used with such connectors.
2. Description of the Prior Art
These and other objects and advantages are achieved with a preferred embodiment of the invention to be described hereinafter in more detail with reference to the accompanying drawings, wherein:
FIG. 1 is a top plan view, with portions broken away, of a cable connector together with quick release clamp in accordance with the present invention; and
FIG. 2 is a sectional view on an enlarged scale taken on line 2--2 of FIG. 1.
Referring now to the drawings, one portion of conventional electric storage battery 10 is shown with a terminal 12 protruding vertically therefrom. A cable 14 is connected to the terminal by means of a cable connector 16 which includes a somewhat semicylindrical base portion 16a with integrally formed ears 16b, 16c extending in a generally parallel relationship therefrom. The ears 16b, 16c are spaced one from the other at 18 and are provided with mutually aligned holes 20. The ears 16b, 16c are laterally constrictable around and against the terminal 12 to electrically connect the cable 14 to the battery.
This lateral constriction is achieved by the clamp of the present invention, which includes a bolt 22 having a threaded shank 22a terminating at one end in an enlarged hexagonal head 22b. The shank 22a is dimensioned to extend through the aligned holes 20 in the ears 16c, 16c, with the head 22b being located on the outermost side of the ear 16b. The bolt 22 has a slit 24 extending axially through the head 22b into the shank 22a.
A cam lever 26 is received in the slit 24 and is rotatably connected to the bolt 22 by means of a pin 28 extending across the slit in a direction transverse to the longitudinal bolt axis. The cam lever has a cam surface 30 lying on a reference circle (not shown) whose center 32 is offset by a distance "d" with respect to the axis of the pin 28.
