Abstract
A cable attachment apparatus for attaching a cable conductor having an outside diameter to a booster cable clamp is provided. The apparatus includes a generally tubular wall defining a receptacle for receiving the cable conductor. The tubular wall has an inside diameter slightly greater than the outside diameter of the cable conductor. The apparatus further includes a plurality of fingers circumferentially and axially spaced about the wall, wherein each finger is closest in the axial direction to another finger disposed at a different circumferential position on the wall.
Claims20
In combination, an attachment apparatus;
- and a multi-stranded booster cable conductor having an outside diameter, the attachment apparatus including:
- a generally tubular wall having an axis and defining a receptacle for receiving the multi-stranded booster cable conductor and having an inside diameter slightly greater than the outside diameter of the cable conductor;
- and
- a plurality of fingers circumferentially and axially spaced about the wall and oriented to grip and retain the multi-stranded booster cable conductor within the receptacle, wherein each finger is closest in a direction parallel to the axis to another finger disposed at a different circumferential position on the wall and includes a base end connected to the wall and a free distal gripping end disposed closer to the axis of the tubular wall than any other portion of the finger.
A booster cable and clamp combination comprising:
- a first lever;
- a second lever pivotally connected to the first lever;
- a cable having a multi-stranded booster cable conductor with an outside diameter;
- and
- a cable attachment apparatus connected to the first lever, the attachment apparatus including
- a generally tubular wall having an axis and defining a receptacle disposed about the multi-stranded booster cable conductor and having an inside diameter slightly greater than the outside diameter of the multi-stranded booster cable conductor, and
- a plurality of fingers circumferentially and axially spaced about the wall and projecting radially inwardly therefrom in engagement with the cable conductor, wherein each finger is closest in a direction parallel to the axis to another finger disposed at a different circumferential position on the wall, the fingers collectively applying to the multi-stranded booster cable conductor a first retention force in a first axial direction and a second retention force in a second axial direction, wherein the first retention force is greater than the second retention force.
In combination, a jaw and cable attachment apparatus;
- and a multi-stranded booster cable conductor having an outside diameter, the attachment apparatus including:
- a jaw portion for making an electrical connection with an associated terminal;
- a generally tubular wall having an axis and forming a receptacle integral with the jaw portion for receiving the multi-stranded booster cable conductor and having an inside diameter slightly greater than the outside diameter of the multi-stranded booster cable conductor;
- and
- first and second sets of circumferentially spaced fingers extending radially inwardly from the wall and oriented to grip and retain the multi-stranded booster cable conductor within the receptacle and disposed, respectively, at first and second axial positions along the wall, wherein each of the fingers of the first set of fingers is at a different circumferential position than each of the fingers of the second set of fingers, the first and second sets of fingers collectively applying to the multi-stranded booster cable conductor a first retention force in a first axial direction and a second retention force in a second axial direction, wherein the first retention force is greater than the second retention force.
