7 Claims. (01. 173-259) The present invention relates broadly to the clamp 5 having a pivotal connection 6 with the art of electrical conductors, and more particuterminal member. The terminal member is prolarly to conductors of such character adapted to vided on one side thereof with a substantially be utilized as detachable connecters for storage semi-circular bearing portion '7 adapted to sur- 5 batteries and the like. round substantially one-half of a battery post, the

The connection is customarily made through the Inorder ,to make the structure as compact as medium of a deformable clamp employing a bolt possible, the meeting plane 9-9 between the or the like for drawing the parts of the clamp into portions -7 and 8 preferably not only extends firm electrical contact about the post.

is not thus limited. Such a connecter preferably To those skilled in the art it will be apparent comprises a terminal member sand a swinging h t sprin 14. b s lected as to insure the 1 maintenance of the portions 7 and 8 in proper engagement. with a battery post and the establishment of a proper electrical connection therebetween; This electrical connection is further insured by the provision of circumferentially extending ribs 24 and 25 formed respectively on the portions '7 and 8, thus providing localized contact zones adapted to more effectively bite into the battery post and thus not. only insurea good electrical connection therebetween, but also minimize the possibility of loosening of this connection. This is particularly desirable in the case of tapered posts as herein illustrated, although the invention is equally applicable in connection with substantially cylindrical posts.

From the foregoing description, it will be apparent that I have provided a detachable connecter comprising but two body members, one of which not only forms a terminal connecter, but a housing for an actuating spring, and the other of which forms a clamp and cover for the housing. Inasmuch as the construction is such that substantially half of the post is embraced by the portion 7 of the connectenan efiective current carrying path'of short length from the post to the cable 11 is provided. The location of the pivotal connection 6, made possible by reason of the angular meeting plane of the portions 7 and 8, precludes the use of relatively long lugs or brackets forming a mounting for the pivot pin itself.

Further advantages arise from the provision of a terminal member of such structure as to provide a cable receiving recess and spring housing therein in substantially axial alinement, thus reducing the over-all diameter of this member.

Further advantages arise from the provision of an actuating spring having its efi'ective axis angularly disposed relatively to the meeting plane between the post engaging clamps whereby the post itself cooperates with the spring in maintaining the clamping portions in the desired relationship to the post.

While I have herein illustrated and described the preferred form of my invention, it will be understood that changes in the construction, contour and relationship of the parts may be made without departing either from the spirit of my invention or the scope of my broader claims.

- I claim:

housed within said recess, a swinging clamp pivotally connected to said member and normally urged intoyclamping engagement therewithby said spring, said clamp having a handle portion projecting therefrom in opposed relationship to said lug and forming with said lug compressing means for' said spring, said clamp further forming a closure for said spring recess. 3. A detachable connecter for batteries comprising a split member with the portions pivoted to each other, said portions together defining a cylindrical opening adapted to receivea battery post, one portion of said split member having an enlargement recessed to receive a cable end and recessed to house a spring, and a spring therein for urging the portions of the member into clamping engagement with the Oppo ite sides of the post, the recess housing the spring being adjacent the pivot between said portions and the cable recess being remote from said pivot.

4. A dc hable connecter for batteries, including a terminal member having a recess for permitting a battery post to be partially set into said member, a swinging clamp pivotally connected to said member, a cable connected to said member on the opposite side of said recess from the pivot of said clamp, and a coil spring for normally urging the clamp into engagement with the opposite side of the post from said member, said member having a cylindrical recess therein housing said spring and conforming substantially to the overall dimensions of the spring, and said clamp forming a closure for one end of said spring recess.

5. A detachable connecter for batteries, including a terminal member having a cable receiving recess in one end thereof, a spring receiving recess in the opposite end thereof, said recesses being cylindrical and in substantially axial alignment, a post receiving recess for permitting a battery post to be partially set into said member, a compression spring in said spring recess, and a swinging clamp pivotally connected to said member with the axis of the pivot on the opposite side of the post recess from the cable recess, said clamp being normally urged pivotally into clamping engagement with the opposite side of the post from said member by said spring.

8. A detachable connecter for batteries, including a terminal member having a cable receiving recess, a spring receiving recess, a post receiving recess for permitting a battery post to be partially set into said member, a compression spring in said spring recess, and a swinging clamp pivotally connected to said member with the axis of the pivot on the opposite side of the post recess from the cable recess, said clamp being normally urged into clamping engagement with the opposite side of the post from said member by said spring, said clamp having a portion overlying the end of said springrecess and engaged by said compression spring.

7. A detachable connecter for batteries, including a terminal-member having a recess for receiving one side of a battery post, a swinging clamp having a contact portion for engaging the other side of the post, a cable connected to said member on the opposite side of said recess from the pivot of said clamp, a cylindrical recess in said terminal member on an axis angularly related to the meeting plane of the terminal member and swinging clamp, and a compression spring housed within said cylindrical recess for normally urging the clamp into engagement with the post.
