Abstract

A battery terminal includes a penetrating plate disposed to penetrate annular portions from one end portions of the annular portions to the other end portions of the annular portions with slits interposed therebetween; a fastening bolt supported by a threaded hole of the penetrating plate to be rotatable about an axial direction; and a spacer as a pressing force converting member disposed to come into contact with edge portions of the annular portions from an end portion side of the penetrating plate where the threaded hole is provided, and converts an axial-direction fastening force, which is generated between the fastening bolt and the threaded hole with the rotation of the fastening bolt about the axial direction, into a long-side-direction pressing force that presses the annular portions in a direction, in which intervals of the slits of the annular portions are reduced, of a long-side direction.

First claim

What is claimed is:

1 . A battery terminal comprising:
an annular portion in which a post insertion hole into which a battery post is inserted and a slit connected to the post insertion hole are formed; a holding member that is disposed so as to extend from one end portion of the annular portion to the other end portion of the annular portion with the slit interposed therebetween in a width direction that is a direction crossing an axial direction of the battery post and crossing the slit; an annular portion holding portion that is provided at one end portion of the holding member and holds the annular portion; a fastening member supporting portion that is provided at the other end portion of the holding member; a fastening member that is supported by the fastening member supporting portion so as to be rotatable about the axial direction; a member to be fastened that is threadably engaged with the fastening member; and a pressing force converting member that is disposed so as to come into contact with the annular portion from the other end portion side of the holding member and converts an axial-direction fastening force, which is generated between the fastening member and the member to be fastened with the rotation of the fastening member about the axial direction, into a width-direction pressing force that presses the annular portion in a direction, in which an interval of the slit of the annular portion is reduced, of the width direction.

2 . The battery terminal according to claim 1 , wherein
the holding member is a penetrating plate that is disposed so as to penetrate the annular portion from one end portion of the annular portion to the other end portion of the annular portion with the slit interposed therebetween in the width direction that is the direction crossing the axial direction of the battery post and crossing the slit, and the annular portion holding portion is a retaining portion that is provided at one end portion of the penetrating plate and prevents the penetrating plate from being detached from the annular portion.

3 . The battery terminal according to claim 2 , wherein
the member to be fastened includes a threaded hole that is provided at the other end portion of the penetrating plate so as to pass through the penetrating plate in the axial direction, the fastening member is a bolt that is threadably engaged with the threaded hole so as to be rotatable about the axial direction, the fastening member supporting portion includes the threaded hole, the pressing force converting member is a spacer which is disposed so as to be movable relative to the penetrating plate in the width direction and of which one end in the width direction comes into contact with a head portion of the bolt and the other end in the width direction comes into contact with the annular portion, a tapered surface is formed on at least one of the head portion of the bolt that comes into contact with the spacer, and the other end of the spacer that comes into contact with the bolt, and the tapered surface is inclined in a direction in which an axial-direction pressing force of the bolt pressing the spacer by a fastening force, which is generated between the bolt and the penetrating plate when the bolt approaches the threaded hole with the rotation of the bolt about the axial direction, is converted into a width-direction pressing force of the spacer pressing the annular portion in a direction in which an interval of the slit of the annular portion is reduced.

4 . The battery terminal according to claim 2 , wherein
the fastening member supporting portion includes an elongated hole that is provided at the other end portion of the penetrating plate so as to pass through the penetrating plate in the axial direction and is formed along the width direction, the fastening member is a bolt that is supported by the hole of the penetrating plate so as to be rotatable about the axial direction, the member to be fastened is a nut that faces the bolt with the penetrating plate interposed therebetween in the axial direction, is threadably engaged with the bolt, and includes a tapered surface formed on one end of the nut in the width direction and coming into contact with the penetrating plate, the rotation of the nut about the axial direction being regulated and the other end of the nut in the width direction coming into contact with the annular portion, the pressing force converting member is the nut, and the tapered surface formed on the nut is inclined in a direction in which an axial-direction fastening force, which is generated between the bolt and the nut when the nut approaches the bolt in the axial direction with the rotation of the bolt about the axial direction, is converted into a width-direction pressing force of the nut pressing the annular portion in a direction in which an interval of the slit of the annular portion is reduced.

5 . The battery terminal according to claim 2 , wherein
the fastening member supporting portion includes an elongated hole that is provided at the other end portion of the penetrating plate so as to pass through the penetrating plate in the axial direction and is formed along the width direction, the fastening member is a bolt that is supported by the hole of the penetrating plate so as to be rotatable about the axial direction, the member to be fastened is a nut that faces the bolt with the penetrating plate interposed therebetween in the axial direction and is threadably engaged with the bolt, the pressing force converting member is a spacer that is disposed between the bolt and the penetrating plate so as to allow the bolt to penetrate the spacer and includes a tapered surface formed on one end of the spacer in the width direction and coming into contact with the penetrating plate, the rotation of the spacer about the axial direction being regulated and the other end of the spacer in the width direction coming into contact with the annular portion, and the tapered surface formed on the spacer is inclined in a direction in which an axial-direction fastening force, which is generated between the bolt and the nut when the bolt approaches the nut in the axial direction with the rotation of the bolt about the axial direction, is converted into a width-direction pressing force of the spacer pressing the annular portion in a direction in which an interval of the slit of the annular portion is reduced.

6 . The battery terminal according to claim 2 , wherein
the fastening member supporting portion includes a hole that is provided at the other end portion of the penetrating plate so as to pass through the penetrating plate in the axial direction, the fastening member is a bolt that is supported by the hole of the penetrating plate so as to be rotatable about the axial direction, the member to be fastened is a nut that faces the bolt with the penetrating plate interposed therebetween in the axial direction and is threadably engaged with the bolt, the pressing force converting member includes a first spacer which is disposed between the bolt and the penetrating plate so as to allow the bolt to penetrate the first spacer and of which the rotation about axial direction is regulated, and a second spacer which is disposed so as to be movable relative to the penetrating plate in the width direction and of which one end in the width direction comes into contact with the annular portion and the other end in the width direction comes into contact with the first spacer, a first tapered surface, which comes into contact with the second spacer, is formed on one end of the first spacer in the width direction, a second tapered surface, which comes into contact with the first tapered surface, is formed on the other end of the second spacer in the width direction, a
