1.The positive pole and negative pole of a single battery are led out from one or both ends of the shell, and the exposed parts at the end mainly include pole, conducting bar, etc. after a plurality of batteries are grouped, a shell is covered as a whole.

The structure of the existing battery has the following defects because there is no protective component at the end of the battery, the conductive bar, pole and other parts are easy to be polluted by moisture, dust and other pollutants, thus affecting the normal operation of the battery, reducing its service life, more seriously, it will cause abnormal conditions such as battery short circuit, operation error and poor safety.

2.The utility model discloses a waterproof and dustproof battery, which adds a waterproof and dustproof sealant cover at the end of the battery, covers the parts at the end of the battery, including the conductive bar, pole and other parts, and isolates

them from the outside, prevents them from being polluted by water, dust and other pollutants, improves the safety and reliability of the battery, and extends the service life. In order to achieve the above purpose, the utility model adopts the following

technical scheme: waterproof and dustproof battery, including shell, end cover Electric core, pole ear, pole post and conductive strip are installed in the shell, and the shell is provided with at least one port, the port is sealed by the end cover; the pole

post passes through the end cover, and the two are sealed and matched, the pole post is connected with the electric core through the pole ear, the pole post outside the shell is connected with the conductive strip, the port cover of the shell is

provided with the first sealant sleeve, and the outer wall of the sealant sleeve contacting with the shell is provided with the first sealant sleeve The spring ring and the sealant sleeve cover the components of the battery port in it. Preferably, the shell

is cylindrical. Preferably, the first sealant sleeve in contact with the outer wall of the shell is convex inward, the outer wall of the inner convex part forms a circle of depression, and the depression is sleeved into the spring ring. Preferably, the shell is

provided with two ports which respectively bow out the positive and negative electrodes of the battery. Preferably, the first sealant sleeve is provided with a hole for penetrating and extending the signal line.

3.Preferably, the conductive strip is led out to the outside through the first sealant sleeve, and the conductive strip outside the first sealant sleeve is coated with the first adhesive sleeve, which is connected with the first sealant sleeve. Preferably,

the conductive strip is connected with the second conductive strip after passing through the first sealant sleeve, and a sealing sleeve bracket is arranged outside the connection part of the two, the outer walls of the two sides of the sealing sleeve

bracket are respectively sleeved with the second sealant sleeve and the third sealant sleeve, the outer walls of the second sealant sleeve are sleeved with the second spring ring, the second spring ring compresses the second sealant sleeve and the

sealing sleeve bracket, and the outer walls of the third sealant sleeve are sleeved Insert the third spring ring, the third spring ring compresses the third sealant sleeve and the sealing sleeve bracket; the second conductive strip passes through the

third sealant sleeve, and the second conductive strip outside the third sealant sleeve is wrapped by the third sealant sleeve. Preferably, the outer wall of the sealing sleeve support forms two annular depressions;

the end of the second sealant sleeve is convex inward, and the outer wall of the inner convex part forms an annular depression, and the annular depression is sleeved into the second spring ring; the inner convex part of the second sealant sleeve is

clipped into one of the annular depressions of the sealing sleeve support; or the end of the third sealant sleeve is convex inward, and the inner convex The outer wall of the third sealant sleeve forms an annular depression, the annular depression is

sleeved into the third spring ring, and the inner convex part of the third sealant sleeve is clipped into one of the annular depressions of the sealing sleeve bracket. The utility model also discloses a battery pack, which is composed of a plurality of the

aforementioned batteries, and the batteries are connected by conducting strips. Preferably, the battery is provided with two batteries arranged opposite each other, or the batteries are arranged side by side.
