Abstract

A battery terminal (1) includes a body (10) with C-shaped upper and lower plate mounting portions (21, 41). First and second fastening portion (60, 70) have bolt accommodating portions (65, 75) respectively. A fastening member (80) is assembled with the first and second fastening portions (60, 70) and is configured to reduce the diameters of the upper and lower plate mounting portions (21, 41). The fastening member (80) includes a fastening bolt (81) having a head (82), a column (83) extending from the head (82) and a shaft (84) extending from the column (83). The column (83) is accommodated into the bolt accommodating portions (65, 75), and a nut (85) is screwed onto the shaft (84). The shaft (84) is insertable through the bolt insertion hole (87) of a washer (86), but the column (83) is not insertable through the bolt insertion hole (87).

Claims6

Dependent claims

A battery terminal to be mounted on a battery post provided on a battery, comprising:

a terminal body with arcuate first mounting portion and second mounting portion arranged to face each other and to surround the battery post, a first fastening portion coupling one of both end parts of the arcuate first mounting portion and one of both end parts of the arcuate second mounting portion and including a bolt accommodating portion, and a second fastening portion coupling the other of the both end parts of the arcuate second mounting portion and the other of the both end parts of the arcuate second mounting portion and including a bolt accommodating portion;
and
a fastening member configured to press the first and second fastening portions in directions toward each other and to deform the first and second mounting portions to reduce diameters thereof by being assembled with the first and second fastening portions;
the fastening member including:
a fastening bolt having a head, a column extending from the head and to be accommodated into the bolt accommodating portions and a shaft extending from the column, the shaft being in the form of a cylinder thinner than the column and having an external thread on an outer peripheral surface;
a nut to be screwed onto the shaft;
and
a sandwiching member having a polygonal outer shape with a plurality of sides, the sandwiching member further having a bolt insertion hole, the shaft being insertable through the bolt insertion hole, but the column being not insertable through the bolt insertion hole, and configured to sandwich the first and second fastening portions between the sandwiching member and the head by inserting the shaft through the bolt insertion hole and assembling the sandwiching member between the column and the nut, wherein:
the second mounting portion includes a sandwiching member rotation stopping portion configured to restrict rotation of the sandwiching member by coming into contact with any one of the plurality of sides of the sandwiching member.
