Technical Field

The invention relates to the technical field of lithium batteries, in particular to pole penetrating terminals for lithium batteries.

Background

Conventional through terminals have disadvantages, such as large size, high height, which affect the internal size of the battery pack, and further, for example, they may be loosened due to design defects and long-term use and battery case fitting, or they may be fixed by 4 bolts to prevent loosening, which increases the installation time and labor cost.

The invention aims at the demands and designs of the pole in the market, and realizes the characteristics of small volume, simple and firm installation, easy production and the like.

Disclosure of Invention

The invention aims to provide pole penetrating terminals for lithium batteries, which are used for solving the problems in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme:

kind utmost point post for lithium cell runs through terminal, including running through main part, bolt post and through the nut, it is equipped with through hole and draw-in groove to run through the main part middle part, is equipped with on the bolt post and runs through the main part, and the bolt post is worn into the through hole that runs through the main part, runs through the main part and passes the battery case, uses the nut that runs through to play at through the inseparable cooperation of main part and battery case.

According to a further aspect of the invention at , the penetrating body includes two retention posts for preventing the terminal from rotating loose.

As a further step of the present invention, the threaded post includes upper and lower threads for externally connecting a bolt to effect the transmission of electrical current.

According to the scheme of step of the invention, the bolt limiting column of the bolt column is tightly matched with the clamping groove penetrating through the main body at the position .

According to a further aspect of the present invention, the penetrating nut includes a threaded hole and the penetrating body includes a threaded post that mates with the threaded hole.

According to a step of the method, the penetrating body and the penetrating nut are both made of ABS plastic.

According to a further of the present invention, the threaded post is made of copper.

Compared with the prior art, the invention has the beneficial effects that: the pole penetrating terminal for the lithium battery realizes the transmission of current from the inside of the shell to the outside of the shell (without electric leakage), and has the characteristics of small volume, simple and firm installation, easy production and the like.
