Description

  The present invention relates to a battery terminal that is fastened to a battery post.

  Conventionally, as a battery terminal attached to a battery post that is an electrode of a battery, a conductive arc part is fitted to the battery post, and a fastening bolt is inserted through a pair of fastening pieces connected to the ends of the arc part. After that, there are some which are attached to the battery post by screwing the nut and fastening the fastening bolt to the nut (for example, see Patent Document 1).

In the above-described prior art, when fixing to the battery post, it is necessary to tighten the tightening bolt in the horizontal direction. Various parts are densely mounted in the engine room of a recent automobile, and it is difficult to fasten the fastening bolts in the horizontal direction due to the problem of interference with other parts. On the other hand, the upper part of the engine room is less likely to hinder bolt tightening work, and in order to improve the workability of mounting the battery terminal on the battery post, it is better to tighten the bolt in the vertical direction instead of in the horizontal direction. There are many cases.

A fastening bolt is mounted on the flat plate facing upward, and a post insertion hole penetrates to the side thereof, and a pair of support portions are formed on the flat plate from above the opposing portion around the post insertion hole. A terminal plate on which a post receiving portion is formed so that the upper end thereof is positioned above the post insertion hole, and a cylindrical portion having an inner diameter larger than the outer diameter of the battery post, and A clamping body that is connected to the bottom of the cylindrical part and has a pressing plate that extends obliquely with respect to the axial center of the cylindrical part, and includes either the terminal plate or the clamping body, Electric power input / output wires are electrically connected,
After the pressing plate portion of the fastening body is inserted between the pair of support portions of the terminal plate, the fastening bolt is passed through the pressing plate portion, and the fastening body is placed above the terminal plate. The battery post protrudes from the post insertion hole and the cylindrical portion, and the post receiving portion faces the surface of the battery post on the side of the tightening bolt. In addition, after the terminal plate and the fastening body are placed on the upper surface of the battery, a nut member is screwed into the fastening bolt to fasten the pressing plate portion to the terminal plate. The cylindrical portion is inclined with respect to the battery post, and the battery post is pressed by the inner periphery of the cylindrical portion on the side away from the pressing plate portion, thereby Battery terminal between said post receiving portion to contact the outer peripheral surface and the surface of the bets, characterized in that it is held nipped the outer peripheral surface of the battery post.   3. The battery according to claim 2, wherein a surface receiving portion is formed at an upper end portion of the cylindrical portion on a side away from the pressing plate portion so as to come into contact with an outer peripheral surface of the battery post. Terminal.   A rotating engagement portion is formed around the post insertion hole of the terminal plate to be engaged with the cylindrical portion and serve as a fulcrum for tilting the cylindrical portion with respect to the battery post. The battery terminal according to claim 2 or claim 3.
