detailed description

The specific embodiment of the present invention will be described in detail below in conjunction with accompanying drawings 1-2.

The battery with easy plugging and unplugging of the present invention includes a battery core body and a battery case 2 for accommodating the battery core body. One end of the battery case 2 is a charging and discharging terminal 3, and the other end of the battery case 2 is a pull-out terminal 4 for charging and discharging. A connector plug 31 is provided on the end 3 .

In order to avoid the defect that the positive and negative poles of the plug-in battery are easily reversed and cause the risk of short circuit, an anti-error component can be arranged on the battery case 2. The structure of the anti-error pit 6 on the pull-out end 4 that matches the shape of the five sets of anti-error bumps is shown in FIG. 1 and FIG. 2 .

5 groups of anti-error bumps include two bar-shaped bumps 5, which are arranged in parallel between the two bar-shaped bumps 5 and the plug 31, and the outer contour of the combination of the three is trapezoidal, and the plug 31 is at the top of the bottom. Location.
