Terminal post connection especially for storage batteries
First Claim
1. Terminal connection apparatus for detachably connecting an electric cable to a terminal post comprising:
- a stirrup joined with said cable and having spaced arms arranged to surround the sides of said terminal post; and
a clamping device located at free ends of the arms and arranged to engage with said free arm ends adapted to be located on opposite sides of said terminal post, said clamping device being placed under tension to press said arms toward each other to a locking position;
said clamping device comprising a first clamp element including a threaded member adapted for rotational movement relative to said arms to adjust the position between the ends of the arms and a second clamp element including a pair of externally threaded coaxial sleeves which are mounted on the threaded member and threadedly engage internal threaded bores in respective stirrup arms, said sleeves having radially projecting maneuvering arms for advancing said sleeves into or out of the respective stirrup arms, and the threads of one sleeve have a pitch opposite to that of the other sleeve.

Abstract
A terminal connection device which is especially adapted for use with storage batteries such as are commonly used in vehicles as a starting battery. The connection device has a plastic protective cap mounted for pivotal movement which can be lifted by swinging through an angle to release the connecting device so that it can be removed from the battery terminal post. Sleeves having oppositely directed threads or cam surfaces close the stirrup arms about the terminal post as the cap is lowered to its protective position. A thread bolt serves to adjust the location of the sleeves to compensate for variations in size of the battery terminal posts.

4. Terminal connection apparatus for detachably connecting an electric cable to a terminal post comprising:
-
a stirrup joined with said cable and having spaced arms arranged to surround the sides of said terminal post; and a clamping device located at free ends of the arms and arranged to engage with said free arm ends adapted to be located on opposite sides of said terminal post, said clamping device being placed under tension to press said arms toward each other to a locking position; said clamping device comprising a first clamp element including a threaded member adapted for rotational movement relative to said arms to adjust the position between the ends of the arms and a second clamp element including a pair of sleeves each having cam surfaces near the outer ends of the stirrup arms, said sleeves being mounted on the threaded member for coaxial rotational movement, and said second clamp element further comprising maneuvering arms that project substantially radially from the cam sleeves whereby contact surfaces on the stirrup arm ends and the cam elements that face each other serve as camming formations in mutual engagement that cooperate in such a way that the stirrup arm ends disposed between the cam surfaces are pressed toward each other when the maneuvering arms are turned. - View Dependent Claims (5)
