Micro-miniature lithium battery structure

Technical Field

The utility model relates to a lithium cell technical field specifically is a lithium cell structure of microminiature.

Background

Lithium batteries are a class of batteries using a non-aqueous electrolyte solution, using lithium metal or a lithium alloy as a positive/negative electrode material, and are used in cardiac pacemakers at the earliest days. The lithium battery has the advantages of extremely low self-discharge rate, mild discharge voltage and the like, so that the pacemaker implanted into a human body can operate for a long time without recharging. Lithium batteries generally have a nominal voltage of greater than 3.0 volts and are more suitable as integrated circuit power supplies. The manganese dioxide battery is widely used in calculators, digital cameras and watches, and the installation efficiency is influenced because the installation process is too complicated when the protection structure is installed in the current micro lithium battery structure.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is an enlarged view of a portion a of fig. 1 according to the present invention.

Wherein, 1 battery body, 2 lag, 3 sealed lids, 4 springs, 5 recesses, 6 movable plates, 7 fixed blocks, 8 draw-in grooves, 9 cardboard, 10 bull sticks, 11 support rings, 12 baffles.

Detailed Description

As shown in fig. 1-2, the embodiment of the utility model provides a lithium battery structure of microminiature, including the battery body 1, lag 2 has been cup jointed to the outside of battery body 1, the top joint of battery body 1 has sealed lid 3, the lower surface of sealed lid 3 and the top overlap joint of lag 2, the left side fixedly connected with support ring 11 of lag 2, the inside swing joint of support ring 11 has bull stick 10, the bottom fixedly connected with baffle 12 of bull stick 10, the right side fixedly connected with cardboard 9 of bull stick 10, the quantity of cardboard 9 is two, two cardboard 9 are with the axis symmetry setting of sealed lid 3, draw-in groove 8 has been seted up in the left side of sealed lid 3, the inside joint of the surface of cardboard 9 and draw-in groove 8, recess 5 has been seted up at the top of lag 2, the interior diapire fixedly connected with spring 4 of recess 5, the top fixedly connected with movable plate 6 of spring 4, the upper surface overlap joint of movable plate 6 has fixed block 7, the upper surface of fixed block 7 is beaten with the lower surface of sealed lid 3 and is connected.

The working principle is as follows: put into the inside of lag 2 with the battery body 1, place sealed lid 3 at the top of the battery body 1 and press down afterwards, make sealed lid 3 drive fixed block 7 with movable plate 6 extrusion downwards, this in-process spring 4 keeps by the extruded state, rotate bull stick 10 afterwards, make bull stick 10 card go into the inside of draw-in groove 8, relieve sealed lid 3 afterwards, utilize spring 4's elasticity to give sealed lid 3 thrust upwards, thereby make cardboard 9 can not break away from inside draw-in groove 8.
