AI Technical Summary

Problems solved by technology

However, in general users, etc., torque management is not performed, and there is a chance of tightening at a high torque value.
In this case, if the terminal is not highly resistant to tightening, damage to the bushing or airtightness between the bushing and the cap cannot be ensured when tightening is repeated during maintenance etc.

Embodiment

[0036] (Bushing A)

[0037] like figure 1 As shown, a substantially V-shaped pattern formed by cutting the upper surface, side surfaces, and lower surfaces of the annular protrusion 3 is provided in a part of the entire circumference of the annular protrusion 3 except for the uppermost stage (the fifth stage). The bushing of the continuous notch part 4 connected by the notch 4a of the type. Here, a Pb-Sb alloy (Pb:Sb=0.974:0.026) was used for the bushing.

[0038] (Bushing B)

[0039] As for the bushing A, the same bushing as that of the bushing A was manufactured except that the annular protrusion 3 of the uppermost stage was provided with the same continuous notch portion 4 as that of the other stages.

[0040] (Bushing C)

[0041] As for the bushing B, the same bushing as that of the bushing B was produced except that the continuous notch 4 was provided on the entire circumference of the annular protrusion 3 .

[0042] (Bushing D)

[0043] For Bushing A, except as f...

Abstract

A lead-acid battery bushing (1) according to the present invention is insert-molded into a resinous cap. The bushing (1) has a hollow cylindrical shape, and a plurality of stages of ring-shaped projections (3) are formed on the outer circumferential surface of the bushing (1). A continuous notch portion (4) in which notches (4a) extend is formed on parts of the entire circumferences of the ring-shaped projections (3). The notches (4a) are formed by cutting all of the upper, side, and lower surfaces of the ring-shaped projections (3) to have a substantial V-shape in a plan view.

Description

technical field [0001] This invention relates to the bush for lead acid batteries, and the lead acid battery using the same. Background technique [0002] In a lead-acid storage battery for automobiles, etc., a plate group in which a positive plate and a negative plate face each other with a separator interposed therebetween is housed in a unit cell compartment in which the inside of the cell is partitioned by a partition plate. Adjacent cell chambers of different polarities are connected to each other by connecting members, and lead alloy poles are connected to one polarity of the cell chambers at both ends. Insert-molded lead alloy bushings are provided on the cover that closes the opening of the battery cell, and one end of the polarity is inserted into the bushing and integrated by welding or the like to form a terminal of the lead-acid battery. [0003] There is a slight gap between the resin cap and the lead alloy bush because there is no joining force even if they ar...
