Description

[Detailed description of the invention] (Industrial application field) The present invention has a nut insertion hole in the shape of a square prism, which is formed through the hole in the width direction, and which is formed on at least two of the front, top, and back surfaces. , relates to a terminal portion of a lead-acid battery comprising a rectangular prism-shaped terminal in which a bolt communication hole communicating with the nut insertion hole is formed, and a nut inserted into the nut insertion hole of this terminal.

(Prior art) In vehicles such as motorcycles, which have many models and are compactly designed, the volume and shape of the space for installing lead-acid batteries are extremely limited, and for this reason, it is difficult to use lead-acid batteries of the same size. Depending on the model, the wire harness terminal on the motorcycle to which it is connected is different: one is attached from the front of the lead-acid battery, and the other is attached from the top.
In order to cover this problem with one type of lead-acid battery, for example, there is a lead-acid battery that has two bolt insertion holes, one in front of the terminal and one on the top surface. This is done by drilling a square columnar nut insertion hole through the terminal from the side of the square columnar terminal, and inserting the square columnar nut into the nut insertion hole from the side. The terminal can be attached from either the front or the top.
Furthermore, since the screw threads of the bolts and nuts will be damaged due to corrosion etc. by the time the lead-acid battery reaches the end of its lifespan, these can be replaced freely.

(Problem that the invention aims to solve) When maintenance is performed on a motorcycle, the stand bar is erected, so the motorcycle is tilted. In addition, to reinstall a lead-acid battery that has been removed, use one hand to align the terminal hole on the wire harness side with the bolt insertion hole of the lead-acid battery terminal, and use the other hand to insert the bolt. Therefore, in the above conventional configuration,
For motorcycles that tilt in the direction in which the nut starts to slide even if the nut is inserted from the side,
There was an inconvenience that the nut would slide out if you let go of it, so you couldn't install the lead-acid battery by yourself.

(Means for Solving the Problems) In order to solve the above problems, the terminal portion of the lead-acid battery of the present invention is formed with a square columnar nut insertion hole penetrating in the width direction, and has a front surface, a top surface, and a back surface. A terminal for a lead-acid battery comprising a rectangular prism-shaped terminal having bolt communication holes formed in at least two or more surfaces thereof, each communicating with the nut insertion hole, and a nut inserted into the nut insertion hole of this terminal. In the part, a magnetic stopper is provided near one side of the terminal, so that the nut can be inserted into the nut insertion hole in each orientation whether the screw hole of the nut is in the horizontal or vertical direction. This is what I did.

(Function) Even if one side of the terminal is inclined diagonally downward, the magnetic stopper reliably prevents the nut from sliding out of the nut insertion hole, regardless of the nut insertion orientation.

(Example) Hereinafter, an example of the present invention will be described based on FIGS. 1 to 6.

Fig. 1 is an external perspective view of the terminal section of a lead-acid battery according to an embodiment of the present invention, Fig. 2 is a cutaway plan view of the main part, Fig. 3 is a front view of the same, and Fig. 4 shows the screw hole of the nut. Figure 5 is the same side view when the nut is inserted in a horizontal position, and Figure 6 is the same side view when the nut is installed in a position where the screw hole of the nut is in the vertical direction. is a plan view of the nut, 1 is the lid of the lead-acid battery, and there is a rectangular prism-shaped recess 2 at the top left corner of the front.
is formed, and a square column-shaped lead alloy terminal 4 protrudes from the bottom surface 3 of the recess 2.
A nut insertion hole 5 in the shape of a square column is formed through the hole 5 in the width direction. That is, the nut insertion holes 5 are open on both sides of the terminal 4, and the opening surfaces are square. The terminal 4 also has a circular bolt insertion hole 6 on the front and a similar bolt insertion hole 7 on the top.
Each of them communicates with the nut insertion hole 5.

A magnetic stopper 8 is made of, for example, polypropylene resin mixed with ferrite magnetic powder, and is attached near the right side surface of the terminal 4. Reference numeral 10 denotes a hexagonal nut made of a material having magnetic absorption (the property of being attracted by magnetic force), such as mild steel. Although a hexagonal nut is used in the embodiment, it may be in the shape of a square prism.

The vertical and horizontal dimensions A1 (FIG. 4) of the nut insertion hole 5 are set slightly larger than the vertical angle dimension A2 (FIG. 6) of the hexagonal nut 10. That is, they are formed to have a dimensional relationship of A1<A2. The position of the stopper surface 9 of the magnetic stopper 8 is such that when the nut 10 is inserted into the nut insertion hole 5 from the left side of the terminal 4 with the screw hole 11 of the nut 10 in a horizontal direction, the bolt will not pass through. The dimension B1 (FIG. 3) between the center of the hole 6 and the stopper surface 9 is the dimension B2 between the center of the screw hole 11 of the hexagonal nut 10 and the end surface of the hexagonal nut 10.
(Fig. 6) is set to almost match.
That is, the dimensional relationship is B1≈B2. Furthermore, when the nut 10 is inserted into the nut insertion hole 5 from the left side of the terminal 4 in a posture such that the screw hole 11 of the nut 10 is in the vertical direction, the bolt insertion hole 7 on the top surface of the terminal 4 also has the same relationship as above. is set to be.

When tightening a bolt by inserting it into the bolt insertion hole 6 on the front side of the terminal 4, this effect is achieved by inserting the hexagonal nut 10 into the nut insertion hole from the left side of the terminal 4, with the screw hole 11 of the hexagonal nut 10 in a horizontal direction. 5, the hexahedral flat part of the hexagonal nut 10 is attracted to the stopper surface 9, so that the motorcycle side is tilted so that the left side of the terminal 4 faces diagonally downward. Even if the nut insertion hole 5
This prevents the hexagonal nut from sliding out. After this, let go of the hexagonal nut 10, handle the wire harness terminal on the motorcycle side with either hand,
The bolt can be screwed into the threaded hole 11 of the hexagonal nut 10 using the other hand.

When inserting a bolt into the bolt insertion hole 7 on the top surface of the terminal 4 and tightening it, insert the hexagonal nut 10 into the terminal 4 so that the screw hole 11 of the hexagonal nut is in the vertical direction.
When inserting the terminal 4 into the nut insertion hole 5 from the left side (inserting it with your fingertips), the hexahedral flat part of the hexagonal nut 10 is attracted to the stopper surface 9, so that the left side of the terminal 4 faces diagonally downward. Even if a motorcycle or the like is tilted, the hexagonal nut is prevented from sliding out of the nut insertion hole 5. Thereafter, the user can release the nut 10, handle the wire harness terminal on the motorcycle side with either hand, and use the other hand to screw the bolt into the screw hole 11 of the hexagonal nut 10.

(Effects of the invention) As explained above, according to the invention, a magnetic stopper is attached near one side of the terminal,
Since the stopper surface is set at a position where the flat part of the hexahedron of the hexagonal nut comes into contact with the stopper surface of the magnetic stopper when the screw hole of the hexagonal nut and the bolt insertion hole of the terminal almost match, Regardless of whether the hexagonal nut's screw hole 11 is in the horizontal direction or the hexagon nut's screw hole 11 is in the vertical direction, the screw hole of the nut inserted into the nut insertion hole 5 is The nut can be inserted in a position where the bolt insertion hole of the terminal almost matches up with the bolt insertion hole of the terminal, and the side of the terminal on the nut insertion side is facing diagonally downward. Since the nut is attracted by the magnetic stopper regardless of its orientation, it is possible to reliably prevent the nut from slipping out, and the installation work of the lead-acid battery can be easily and quickly performed by one person.

To take out the inserted nut, remove the bolt, pinch the nut with tweezers, etc., and pull it out in the direction in which the nut slides out, making it easy to replace the nut when the threaded portion becomes corroded.
