Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, example 1: the embodiment of the utility model provides an in, a utmost point post runs through terminal for lithium cell, including running through main part 1, bolt post 6 and through nut 10, run through main part 1 middle part and be equipped with through hole 2 and draw-in groove 3, be equipped with on the bolt post 6 and run through main part 1, bolt post 6 pierces into through hole 2 that runs through main part 1, runs through main part 1 and passes battery case 12, uses through nut 10 will run through main part 1 and the inseparable cooperation of battery case 12 and be in the same place.

Two limiting columns 4 for preventing the terminal from rotating and loosening are arranged on the penetrating main body 1. The threaded stud 6 contains an upper thread 7 and a lower thread 9 for the external bolt to effect the transmission of current. The bolt limiting column 8 of the bolt column 6 is tightly matched with the clamping groove 3 penetrating through the main body 1. The through nut 10 is provided with a threaded hole 11, the through body 1 is provided with a threaded column 5, and the threaded column 5 is matched with the threaded hole 11. Therefore the utility model discloses utmost point post runs through the terminal for the lithium cell has realized the transmission (no electric leakage) outside the electric current from the casing in to the casing.

Example 2: on the basis of embodiment 1, the penetrating main body 1 and the penetrating nut 10 are both made of ABS plastic, so that the leakage situation does not occur, and the threaded stud 6 is made of copper.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
