Battery terminal
A battery terminal includes a main body in which a battery post is inserted and a fastener having a pair of fastening abutting portions. The main body has a notch portion provided in at least an end in a fastening direction, accommodating and positioning one of the pair of fastening abutting portions. An abutting-portion-side opposite surface on the fastening abutting portion side and a notch-portion-side opposite surface on the notch portion side have respective abutting surfaces. A relief surface is provided on at least one of the abutting-portion-side opposite surface and the notch-portion-side opposite surface such that a relief space is formed with a clearance from the other one of the opposite surfaces.
1. A battery terminal comprising:
a main body that has a post insertion hole in which a battery post is inserted and a slit being continuous to the post insertion hole; and
a fastener that has a pair of fastening abutting portions abutting and fastening the main body from both sides in a fastening direction interposing the slit along the fastening direction that is a direction intersecting with an axis direction of the battery post and crossing the slit, wherein
the fastener includes a shaft portion, a bolt head, a washer, and a nut,
the shaft portion is provided to the main body in a manner extended from an end of the main body to another end of the main body across the slit along the fastening direction,
one of the pair of fastening abutting portions is the bolt head that is connected to an end of the shaft portion,
another of the pair of fastening abutting portions is the washer,
the nut is screwed onto the shaft portion,
the main body has a notch portion that is provided in at least an end in the fastening direction and accommodates and positions one of the pair of fastening abutting portions,
the fastening abutting portion and the notch portion, with the fastening abutting portion accommodated in the notch portion and positioned, are abutted against each other in the fastening direction, an abutting-portion-side opposite surface being provided at the fastening abutting portion and a notch-portion-side opposite surface being provided at the notch portion are opposite to each other in an opposite direction intersecting with the axis direction and the fastening direction,
with the fastening abutting portion accommodated in the notch portion and positioned, the abutting-portion-side opposite surface and the notch-portion-side opposite surface form respective abutting surfaces abutting with each other,
the abutting surface of the notch-portion-side opposite surface abuts against the abutting surface of the abutting-portion-side opposite surface to prevent the rotation of the fastening abutting portion, and
a relief surface is provided on one of the abutting-portion-side opposite surface and the notch-portion-side opposite surface such that a relief space is formed with a clearance between the relief surface and a non-abutting surface of the other one of the notch-portion-side opposite surface and the abutting-portion-side opposite surface of at least one of the bolt head and the washer.
2. The battery terminal according to claim 1 , wherein
the main body further includes another notch portion,
the notch portions are formed on respective ends on both sides in the fastening direction of the main body, and
the relief surface is provided on the notch-portion-side opposite surface of one of the notch portions.
