Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery post for a battery mounted on an automobile, and more particularly to a battery post which can be directly connected to a battery post at a plurality of locations.

[0002]

2. Description of the Related Art Conventionally, connection between a battery post of a battery and a power supply line is performed through a battery terminal which is externally fitted and fixed to the battery post. As shown in FIG. 4, the battery terminal 2 has an electrode fitting portion 3a of the battery terminal 3 externally fitted to a battery post 2 protruding from the upper surface of the battery 1, and a bolt 4 of a pair of fastening plate portions 3c. Then, the nut 6 is tightened from the horizontal direction with the impact wrench 5 lying down on the bolt 4, and the electrode fitting portion 3 a is pressed against the battery post 2, and the battery terminal 3 is connected to the battery post 2.
It is fixed to.

[0003] The connection between the battery terminal 3 and the power supply line is performed by crimping an electric wire to a barrel formed to extend to one of the fastening plate portions 3c of the battery terminal 3 or by connecting a flat plate portion to the fastening plate portion 3c. Is extended to protrude a stud bolt, and a terminal crimped to an electric wire is fixed to the stud bolt.

[0004]

As described above, in the prior art, the battery terminal 3 is fixed to the battery post 2 of the battery, and the power supply line is connected to the battery terminal 3, so that the battery terminal 3 is always used. 3 and the power supply line could not be directly connected to the battery post 2.

[0005] In recent years, the number of components installed in an engine room in which a battery of an automobile is mounted has become extremely large and the density has been increased. Therefore, it is often difficult to tighten the battery terminal from the horizontal direction with the impact wrench as described above, and in some cases, the tightening cannot be performed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has improved the shape of a battery post and, as in the conventional case, can be connected to a power supply line via a battery terminal. A power supply line can be directly connected to the post so that the post can be selectively used, and in some cases, two power supply circuits can be connected to the battery post using both of them.

[0007]

That is, according to the present invention, there is provided a battery post of a battery mounted on an automobile according to the present invention, wherein the main body has a substantially cylindrical shape to which a battery terminal is fitted. It consists of a bolt protruding from the upper end surface of the part, and the battery terminal is externally fitted to the main body part and tightened and fixed, and the bolt part is inserted with the terminal hole connected to the wire terminal and tightened with a nut A battery post characterized by being configured to be fixed is provided.

As described above, in the battery post of the present invention, the battery terminal can be externally fitted and fixed to the cylindrical main body, and the terminal can also be connected to the bolt protruding from the upper end surface of the main body. It can be fixed and connected with a nut. Therefore, when the battery terminal cannot be attached, the terminal can be connected to the bolt portion and the power supply line can be connected to the battery. Furthermore, when the battery terminal can be externally fitted and fixed to the main body, a power supply line can be connected through the battery terminal, and a power supply line can also be connected to the bolt portion. Two can be provided.

A starter motor and / or
Alternatively, the terminal of the wire terminal connected to the alternator is connected (claim 2).

When the battery terminal can be externally fitted and fixed to the main body of the battery post, the bolt portion is connected to one end of a power supply line connected to a starter motor and an alternator directly connected to the battery (a crimp terminal having a bolt hole). It is preferable to pass through the bolt hole of the terminal) and tighten and fix with a nut. With this configuration, it is not necessary to form a branch circuit to the starter motor and the alternator on the power supply line connected to the battery terminal.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, a battery post 11 protruding from an upper surface of a battery 10 mounted on an automobile is provided at a tip end of an electrode connecting bar 12 protruding into a main body of the battery 10. A body portion 13 having a substantially cylindrical shape (specifically, a truncated cone shape with a reduced upper portion);
And a bolt 14 projecting upward from the center of the upper end surface 13a of the main body 13. A screw 14a is engraved on the outer peripheral surface of the bolt portion 14.

Although the bolt portion 14 is formed integrally with the main body portion 13, it may be formed separately and fixed by welding.

As shown in FIG. 2, the battery post 11 has an LA connected to the end of an electric wire W1 connected to a starter motor (not shown) by crimping.
The terminal 20 is connected to an LA terminal 21 which is crimped to the end of an electric wire W2 connected to an alternator (not shown).

That is, the bolt holes 20 a and 21 a of the LA terminals 20 and 21 are passed through the bolt portion 14, and are tightened and fixed by the nut 22.

On the other hand, the main body 13 of the battery post 11
Also, the battery terminal 25 is externally fitted and fastened and fixed. The conventional battery terminal shown in FIG.
Although a horizontally tightened battery terminal shown in FIG. 3 can be used, a vertically tightened battery terminal 25 as shown in FIG. 3 is preferably used. The battery terminal 25 includes an annular portion 26 that fits over the main body 13, a pair of fastening plate portions 27 a and 27 b, a substrate portion 28, and a stud bolt 29 protruding from the substrate portion 28. 30 and a pair of left and right fastening plate portions 27a, 27b with bolts 32.
To fasten the annular portion 26 to the main body 13 of the battery post 11.

If the above-mentioned vertical tightening battery terminal 25 is used, tightening to the battery post 11 can be performed from above, and no space is required. Therefore, by tightening the LA terminal 31 connected to the terminal of the power supply line 30 to the stat bolt 29 of the battery terminal 25 with the nut 33, a power supply circuit can be formed separately from the connection by the bolt portion 14.

It should be noted that if a horizontal tightening type can be used as the battery terminal, the battery post 11
What is necessary is just to attach the horizontal tightening type battery terminal to the main body part 13 of FIG. Further, when the side-tightening type battery terminal cannot be attached, the bolt 13
Since the power line can be connected to the power supply line, a vertically tightened battery terminal is not necessarily required.

[0019]

As is apparent from the above description, according to the present invention, the bolt is projected upward from the upper surface of the substantially cylindrical main body of the battery post so that it can be connected to the terminal of the power supply line. Therefore, when the battery terminal cannot be attached to the main body, the power line and the battery can be connected using the bolt.

Further, when a power supply line is attached to the bolt portion with the battery terminal attached to the main body, the number of power supply circuits connected to the battery can be increased.

Moreover, since the bolts are projected upward from the upper end surface of the main body, the terminals to be connected can be tightened with nuts from above, and workability is improved as compared with the case where the tightening work is performed from the side. Can do better.
