Description

Battery insulating ring and battery using same

Technical Field

The utility model relates to a battery component, in particular to a battery insulating ring and a battery using the same.

Background

The battery that thing networking equipment was used commonly has alkali manganese cell, nickel cadmium battery, lithium ion battery etc, the both ends of its battery box hat are equipped with positive terminal and negative pole lid respectively, the user often can connect the positive negative pole of battery in the battery compartment to the contrary owing to negligence when installing the battery, even be the battery of placing in the receiver, in case form "three positive one is anti" battery return circuits, the battery of anti-connecing all can produce charging current, the inside self-discharge hydrogen evolution reaction aggravation of battery this moment, lead to the inside atmospheric pressure increase of battery, and then lead to electrolyte to flow out, these electrolyte can corrode the battery frame of electrical apparatus and flow on the circuit board even further corrode the circuit and lead to the electrical apparatus damage, also constitute the threat to human health.

In order to prevent the reverse connection of the batteries, the conventional solution is to modify a reverse connection protection circuit of a circuit of the battery compartment, but the solution is only suitable for the situation that users eliminate old battery compartment equipment. The problem of reverse connection of the battery can be fundamentally solved only by improving the battery.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a battery insulating ring.

The technical scheme for realizing the purpose of the utility model is as follows: a battery insulating ring is arranged on a battery steel shell, one end of the battery steel shell is provided with a positive terminal, and the other end of the battery steel shell is provided with a negative cover; the battery insulation circle inlays to be established and is fixed in the negative pole lid with between the battery steel casing, the battery insulation circle includes the insulation circle body, the upper surface of battery insulation circle body is followed the circumference of battery insulation circle body upwards extends two at least insulating spacers, the horizontal position on top of spacer is higher than the horizontal position on top of negative pole lid, the top of spacer with the vertical separation distance on top of negative pole lid is less than the height of anodal terminal, the upper surface of battery insulation circle body with the vertical separation distance on top of negative pole lid is less than the top of spacer with the vertical separation distance on top of negative pole lid.

Further, each of the spacers extends to the edge covering the negative electrode cover towards one side of the negative electrode cover, and the minimum diameter of the circumference enclosed by each spacer is larger than the diameter of the positive electrode terminal.

Further, the isolation blocks are connected into an integral annular shape.

The second purpose of the utility model is to provide a battery, which comprises the battery insulating ring of the first purpose of the utility model.

The utility model creatively embeds the fixed insulating ring between the cathode cover and the battery steel shell, so that the dustproof effect is achieved, if one sides of the cathode covers of the two batteries are opposite, the horizontal position of the top end of the insulating ring is higher than that of the top end of the cathode cover, so that the cathode covers of the two batteries are mutually isolated, the batteries cannot form a battery loop of 'three positive electrodes and one negative electrode', therefore, the reverse connection of the batteries is prevented, the structure is simple, the processing is easy, and the safety of the storage and the use of the batteries is improved.
