Abstract

A battery terminal includes a main member and ring member, each made from a conductive metal. A stud bolt for cable connection projects from the main member. A post fitting is provided in the ring member. The ring member is placed on top of the main member with one end of the ring member supported by the main member and the other end at an angle floating free above the main member. This other end is passed over the stud bolt and the post fitting of the ring member is fit over the battery post. The battery cable terminals are fit onto the stud bolt. When the nut is tightened on the stud bolt, the terminals are tightened against the ring member, which is at an angle to the battery post, and the post fitting of the ring member is forced down and clamped against the battery post. Thus, securing the battery terminal to the battery post and securing the cable terminals to the battery terminal can be simultaneously completed by a single thread tightening operation.

Dependent claims

A battery terminal for connecting a battery post to a cable, comprising:

(A) a substantially flat main member comprising:
a first post fitting portion having a first battery post fitting hole for receiving the battery post therein;
a ring support provided at a first side of the first post fitting portion;
a cable connector portion provided at a second side of the first post fitting portion;
and
a stud bolt projecting vertically upward from said cable connector portion;
(B) a ring member placed over said main member, comprising:
a second post fitting portion having a second battery post fitting hole for receiving the battery post and a cone-shaped clamping piece projecting upward around an inside edge of the second battery post fitting hole;
a clamping member on one side of the second post fitting portion;
and;
a cable connector portion with a bolt hole on an other side of the second post fitting portion through which said stud bolt is inserted, said cable connector portion being bent at a predetermined angle with respect to said second post fitting portion;
and
(C) a nut mounted onto said stud bolt, whereby the battery terminal is assembled such that the end of the clamping member of the ring member is supported by the ring support of the main member, and the second post fitting portion and the cable connector portion of the ring member are inclined to the main member, and wherein tightening of the nut onto the stud bolt clamps the cable terminal to the ring member and simultaneously pushes the clamping piece of the ring member at an angle over the battery post and down against the battery post;
said main member and said ring member being constructed and arranged such that said first battery post fitting hole is separately formed in and defined by said main member and said second battery post fitting hole is separately formed in and defined by said ring member.

A battery terminal for connecting a battery post to a cable, comprising:

(A) a substantially flat main member comprising:
a first post fitting portion having a first battery post fitting hole for receiving the battery post therein;
a first semiconical clamping piece projecting at one side of an inside face of the first battery post fitting hole and projecting vertically upward from said first post fitting portion of said main member;
a ring support provided at a first side of the first post fitting portion;
a cable connector portion provided at a second side of the first post fitting portion;
and
a stud bolt projecting vertically upward from said cable connector portion;
(B) a ring member placed over said main member, comprising:
a second post fitting portion having a second battery post fitting hole for receiving the battery post therein and a second semiconical clamping piece projecting at one side of an inside edge of the second battery post fitting hole on a side opposite that of the first semiconical clamping piece of the main member and projecting vertically upward from said second post fitting portion;
a clamping member on one side of the second post fitting portion;
and
a cable connector portion with a bolt hole on an other side of the second post fitting portion through which said stud bolt is inserted, said cable connector portion being bent at a predetermined angle with respect to said second post fitting portion;
and
(C) a nut mounted onto said stud bolt, whereby the battery terminal is assembled such that the end of the clamping member of the ring member is supported by the ring support of the main member, and the second post fitting portion and the cable connector portion of the ring member are inclined to the main member, and such that tightening of the nut onto the stud bolt clamps the cable terminal to the ring member and simultaneously pushes the second semiconical clamping piece of the ring member, which is at an angle over the battery post, and moved down to clamp the battery post between the first and second clamping pieces of the ring member and the main member;
said main member and said ring member being constructed and arranged such that said first battery post fitting hole is separately formed in and defined by said main member and said second battery post fitting hole is separately formed in and defined by said ring member.
