The technical scheme of the utility model as follows:

the utility model provides a storage battery terminal, is including the second connecting portion that is used for connecting the first connecting portion of battery utmost point post and is used for external power supply line, first connecting portion on be equipped with battery utmost point post matched with utmost point post hole, second connecting portion include the terminal casing and set up at the inside copper core base of terminal casing, the top surface and the side of terminal casing are equipped with a connecting hole respectively, copper core base on correspond the position of connecting hole is equipped with the screw hole that the wiring was used.

In order to make the external connection of the storage battery terminal with the power line more convenient and quicker, the connecting hole is provided with a chamfer.

In order to avoid the mutual interference influence of the threaded holes, the two threaded holes in the copper core base are arranged in a staggered mode.

In order to make the terminal more stable when fixed, the terminal casing is equipped with the draw-in groove that extends to first connecting portion near the position of bottom.

The copper core base is provided with a positioning boss extending out of the bottom surface of the terminal shell, and the fixing effect of the terminal is further improved by arranging the positioning boss.

The bottom surface of the terminal shell is provided with a mounting hole for taking and placing the copper core base, so that the terminal shell and the copper core base can be conveniently combined and disassembled, and production is facilitated.

In order to further increase the stability of the terminal, the first connecting part is provided with an extension part which is arranged around the pole column hole and extends towards one side of the bottom surface, and the outer surface of the extension part is provided with at least one annular groove.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the utility model discloses a top surface and the side at terminal casing set up a connecting hole respectively, make the electron can provide the installation direction of two differences when external power source line, are applicable to more complicated installation condition, have improved battery fixed mounting's convenience.

2. The utility model discloses the position that is close to the bottom at the terminal casing sets up the draw-in groove that extends to first connecting portion, and the copper core base has the location boss that stretches out terminal casing bottom surface, and the extension surface of first connecting portion bottom surface is equipped with at least one annular groove, through the synergism of the above-mentioned three setting, stability when having improved terminal fixed mounting greatly.
