Abstract

The utility model discloses a battery isolation ring which is arranged on a battery steel shell, wherein one end of the battery steel shell is provided with a positive terminal, the other end of the battery steel shell is provided with a negative cover, the battery isolation ring is positioned between the negative cover and the battery steel shell, the battery isolation ring comprises an isolation ring body, support legs extend out of the bottom of the battery isolation ring body, the support legs are embedded and fixed in a gap between the negative cover and the battery steel shell, the horizontal position of the top end of the battery isolation ring body is higher than that of the top end of the negative cover, and the vertical distance between the top end of the battery isolation ring body and the top end of the negative cover is smaller than the height of the positive terminal. The isolating ring structure enables the negative electrode covers of the two batteries to be incapable of contacting when the negative electrodes of the two batteries are in butt joint, and further enables the batteries to be incapable of forming a three-positive-one-negative battery loop.

Description

Battery isolation ring and battery using same

Technical Field

The utility model relates to a battery component, in particular to a battery isolation 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

One of the objectives of the present invention is to provide a battery separator.

The technical scheme for realizing the purpose of the utility model is as follows: the utility model provides a battery isolation ring, battery isolation ring is located the negative pole lid with between the battery box hat, battery isolation ring includes the isolation ring body, the bottom downwardly extending of battery isolation ring body has the stabilizer blade, the stabilizer blade inlays to be established and is fixed in the negative pole lid with in the clearance between the battery box hat, the horizontal position on the top of battery isolation ring body is higher than the horizontal position on the top of negative pole lid, the top of battery isolation ring body with the vertical separation distance on the top of negative pole lid is less than the height of positive terminal.

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

The utility model creatively embeds the fixed isolation ring between the negative pole cover and the battery steel shell, so that the dustproof effect is achieved, if one sides of the negative pole covers of the two batteries are opposite, the horizontal position of the top end of the isolation ring is higher than that of the top end of the negative pole cover, so that the negative pole covers of the two batteries are isolated from each other, and the batteries cannot form a battery loop of 'three positive poles and one negative pole', thereby preventing the reverse connection of the batteries, having simple structure and easy processing, and improving the safety of the storage and the use of the batteries.

fig. 2 is an enlarged schematic view of a portion a in fig. 1.

Detailed Description

The following detailed description of the preferred embodiments of the utility model refers to the accompanying drawings in which:

as shown in fig. 1 and 2, the battery comprises a battery steel shell 1 and a battery isolation ring 2, wherein one end of the battery steel shell 1 is provided with a positive terminal 11, and the other end of the battery steel shell 1 is provided with a negative cover 3; the battery isolating ring 2 is positioned between the negative electrode cover 3 and the battery steel shell 1; battery isolation circle 2 includes isolation circle body 21, the bottom downwardly extending of battery isolation circle body 21 extends stabilizer blade 22, stabilizer blade 22 inlays to be established and is fixed in negative pole lid 3 with in the clearance between the battery box hat 1, the horizontal position of the top 211 of battery isolation circle body 21 is higher than the horizontal position of the top 31 of negative pole lid 3, the top 211 of battery isolation circle body 21 with the vertical separation K of the top 31 of negative pole lid 3 is less than the height of positive terminal 11.

The battery isolating ring can use rubber/silica gel with excellent sealing performance, so that the support legs can be directly in tight fit with the peripheral wall of the cathode cover and the battery steel shell; the material of battery isolation circle can be the nylon circle that anti-aging performance is excellent, needs label paper to carry on spacingly to the isolation circle this moment to prevent that the isolation circle from deviating from.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent flow transformations made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.

Claims
