Battery space occupying barrel

Abstract

The invention discloses a battery space occupying barrel, which comprises an insulated and transparent shell, an anode metal cap and a cathode metal cap, wherein the shell is a hollow cylinder which is formed by fixedly connecting two half shells; annular grooves are arranged at the positions which are on the inner wall of the shell and close to openings at two ends of the shell along the circumferential direction; the anode metal cap and the cathode metal cap are arranged in the annular grooves at the two ends of the shell respectively; a bump part of the anode metal cap projects out of the opening part at one end of the shell; and the anode metal cap is connected with the cathode metal cap through a conducting cable. The battery space occupying barrel has a simple structure, is used together with a lithium iron phosphate battery, is easy to be distinguished from a real battery, and has high safety.

Description

technical field [0001] The invention relates to a space-occupying tube used in conjunction with a lithium iron phosphate battery. Background technique [0002] The voltage of ordinary alkaline 5th / 7th A battery is 1.5 volts, while the voltage of lithium iron phosphate 5th / 7th battery is 3.2 volts. Most electronic products on the market that use batteries are designed with battery compartments suitable for 1.5 volts. Because lithium iron phosphate batteries have the advantages of high rechargeable times, lithium iron phosphate No. 5 / No. 7 batteries can be used to replace ordinary alkaline batteries in electronic products that use even 1.5-volt batteries, but the same number of place holders is required. (often called a fake battery). Although the spacer has no battery function, it needs to realize the conductive function, and the lower the internal resistance, the better. [0003] The design of the existing spacers on the market is to use the empty battery of lithium iron ...

AI Technical Summary

Problems solved by technology

First of all, the appearance of an empty battery is indistinguishable from that of a lithium iron phosphate battery. Consumers tend to confuse the battery with the spacer, and even put the spacer on the charger to charge it and cause a short circuit.

Secondly, the space-occupying tube is only for space-occupying and conducting. It is completely unnecessary to use an empty battery to realize it. The cost is too high and it is a waste of resources.
