Lead-acid battery, terminal thereof, and method for producing lead-acid battery terminal

Abstract

The present invention provides a lead-acid storage battery terminal, which includes a conductive connection seat capable of being electrically connected to the pole in the terminal slot of the battery cover, which has an assembly support that fits tightly with the terminal slot and a terminal boss that protrudes from the battery cover , the assembly support has an assembly hole for the pole to pass through; the bolt on the conductive connecting ring that can penetrate the lead terminal; the nut with the internal thread that cooperates with the bolt, the nut is fixed on the wiring boss and the bolt and the nut can cooperate Compress the conductive connection ring. The invention realizes the fixation of the lead terminal by cooperating with the bolt and the nut to compress the conductive connection ring. Since the fastening strength of the bolt and the nut is better, the rotation of the conductive connection seat due to the force is reduced, so the rotation caused by the rotation of the terminal is reduced. Potential safety hazards, thereby improving the service life of the battery, while improving the conductivity of the terminal. The present invention also provides a lead-acid battery with the above lead-acid battery terminal and a production method of the lead-acid 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
