Lead acid storage battery and terminal thereof and manufacturing method of lead-acid storage battery terminal

Abstract

The invention provides a lead acid storage battery terminal. The lead acid storage battery terminal comprises a conducting connecting base, a bolt and a nut, wherein the conducting connecting base can be electrically connected with a post in a terminal groove of a battery cover and is provided with an assembling foundation support matched with the terminal groove in a sealing manner and a wiring boss which is protruded out of the battery cover, and an assembling hole which is used for the post to pass through is formed in the assembling foundation support; the bolt can be led onto a conducting connecting ring of a lead terminal; and the nut is provided with inner threads matched with the bolt, the nut is fixed on the wiring boss, and the bolt and the nut can be cooperated with each other to compress the conducting connecting ring. The bolt and the nut are cooperated with each other to compress the conducting connecting wire, so that the lead terminal is fixed; and since the tightening strength of the bolt and the nut is relatively good, the rotation of the conducting connecting base due to the stress can be reduced, the safety potential hazard caused by the rotation of the terminal is reduced, the service life of the battery is further prolonged, and the conducting performance of the terminal is also improved. The invention also provides a lead acid storage battery with the lead acid storage battery terminal and a manufacturing method of the lead acid storage battery terminal.

Description

technical field [0001] The present invention relates to the field of storage battery technology, and more specifically relates to a lead-acid storage battery terminal. The present invention also relates to a lead-acid storage battery having the above-mentioned lead-acid storage battery terminal and a production method of the lead-acid storage battery terminal. Background technique [0002] The terminal is an important part of the lead-acid battery, which is used to realize the connection between the lead pole in the battery and the external conductor. The traditional lead-acid battery terminal includes a holding seat for wrapping the lead pole, the holding seat is installed in the terminal groove on the battery cover, and the outside of the holding seat has an exposed pile head. In the terminal welding process of the battery assembly link, the terminal welding mold is used to cover the pile head, and the lead pole and the pile head are welded together by a cast welding machi...

AI Technical Summary

Problems solved by technology

[0003] In order to reduce the cost, when the battery generally adopts a round pile head, the round pile head needs to be clamped on the pile head by a round chuck to realize the connection of the lead terminals; however, when the torque of the round chuck is large, the holder is more likely to rotate , resulting in damage to the sealing structure between the holder and the battery cover, followed by acid climbing or liquid leakage, affecting the service life of the battery, and in severe cases, it will also corrode the battery rack, connecting wires, copper plates and other electrical equipment, pollute the environment, and cannot get it for a long time processing, more likely to cause safety accidents

Moreover, the round collet is easy to fall off, and the connection strength is low, which affects the electrical conductivity

[0004] In addition, the inner wall of the terminal groove on the current battery cover is conical with a small diameter on the outside and a big inside on the inside. It is more likely to cause false welding between the pole and the pile head, and it is easier to cause breakdown by electric sparks, which also affects the battery. service life, and the void inside the weld leads to low compressive strength of the pile head after welding
