Description

TECHNICAL FIELD The present invention relates to a lead-acid battery terminal.

Prior Art and Its Problems FIG. 1 is a perspective view of a conventional lead storage battery terminal portion, in which 1 is a lid of a lead storage battery, and a prismatic concave portion 2 is formed at a front corner. A terminal 4 made of a lead alloy having a prismatic shape is provided so as to project from the bottom surface 3. The terminal 4 is penetrated by a prismatic nut insertion opening 5 opening on both side surfaces, and the opening surface of the nut insertion opening 5 is square. Further, a bolt insertion hole 6, which penetrates the nut insertion opening 5, on the front surface and the upper surface,
6'is formed. FIG. 2 is a perspective view of a conventional nut. The nut 7 has a rectangular parallelepiped shape and is moved in the C direction with the A surface facing upward and in the C direction with the B surface facing upward. In any case, it is formed so that it can be inserted into the nut insertion port 5. Further, a threaded hole 8 is formed in the B surface, and the position of the threaded hole 8 is the bolt insertion hole 6,
6'is formed and penetrates the nut 7. This operation will be described. For example, when a lead storage battery is mounted on a motorcycle, when the terminal on the wire harness side of the motorcycle is attached from the front, the nut 7 is A
The nut is inserted into the nut insertion port 5 with its surface facing upward, the threaded hole 8 is positioned so as to correspond to the bolt insertion hole 6, and is screwed with a bolt (not shown). When the terminal on the wire harness side of the motorcycle is attached from the upper surface, the nut 7 is inserted into the nut insertion opening 5 with the B side facing upward, and the screw cut hole 8 is formed.
Are positioned so as to correspond to the bolt insertion holes 6'and screwed with bolts (not shown). However, the nut has a special shape,
Since it is a so-called dedicated nut, it cannot be easily obtained if it is lost or damaged. Also, the nuts are homemade and are expensive. In addition, it cannot be applied to models that are attached from the side of the terminal. Further, the handling of the nut itself has a drawback that it takes a lot of trouble to attach the wire harness.

An object of the present invention is to provide a lead acid battery having a terminal having a structure in which a lead wire can be pulled out in any direction by increasing the mounting surface of the lead wire terminal without using a nut.

The present invention is characterized in that it has tapping screw mounting holes 12 on the upper surface, the side surface, and the front surface, and a thin hollow terminal 11 made of a conductive material is projectingly provided on the upper surface of the lid 1. To do.

Embodiment An embodiment of the present invention will be described with reference to the drawings.

FIG. 3 is a perspective view of the external appearance of the lead-acid battery of the present invention, and FIG. 4 is a vertical cross-sectional view taken along the line II 'of FIG. 3, where 1 is a lid and 2 is a lid 1.
A prismatic concave portion 11 formed at the front corner of the hollow terminal 11 is a hollow terminal projecting from the lid 1 in the concave portion 2. The hollow terminal
Reference numeral 11 is a thin material made of a conductive material, such as a copper plate or a mild steel plate, which is manufactured by pressing. As shown in the plan view, front view, and side view of the hollow terminal 11 in FIGS. It is a tapping screw mounting hole formed so as to penetrate therethrough, and is formed in a size capable of producing a tapping effect. 14 is fitted with bushing 15,
The hollow terminal 11 is attached to the lid 1 by fixing the bushing 15 in the bushing attachment hole 14 and fitting the terminal peripheral portion 13 into the groove 16 formed in the lid 1 and fixing the terminal. ing. The lead wire terminal 9 is attached to the hollow terminal 11 and a tapping screw 10 as shown in FIG.

Effect of the Invention In the present invention, by providing the tapping screw mounting holes on the upper surface, the side surface, and the front surface of the hollow terminal as described above, the mounting surface of the lead wire can be increased, and the lead wire can be easily mounted by the tapping screw. The conventional tightening nut is no longer needed, and the conventional nut loss and complicated handling can be eliminated. Further, since the hollow terminal can be manufactured by pressing a thin copper plate or the like, it can be obtained at low cost.
