Abstract
A sealing ring comprises a cylindrical ring body and a step. The ring body contracts towards an opening of the ring body and then retracts to the outer side. When the sealing ring is used for a nickel-hydrogen battery, an electrode tab and a metal shell can be effectively isolated, so that the metal shell and the electrode tab are insulated, and the safety problem of the battery due to short circuit zero connection of the battery when the electrode tab contacts with the inner wall of the metal shell due to the bending angle of the electrode tab is avoided. The utility model further provides the nickel-hydrogen battery using the sealing ring.
Description
Technical field
The utility model relates to the Ni-MH battery of a kind of sealing ring and use sealing circle.
Background technology
Adopt at present the Ni-MH battery of pier envelope sealing process preparation, utmost point group is shorter, and lug is longer, and particularly for low-capacity nickel-hydrogen battery, this point is particularly evident.
The sealing ring of traditional Ni-MH battery is cylindric, and cylinder side wall extends to the center of circle, bottom.The sealing ring of this structure, well the metal shell of isolated electrode lug and battery is easy to contact the metal shell inwall of battery because lug bending angle problem causes lug, causes battery short circuit zero electricity, causes safety problem.
The utility model content
Based on this, be necessary to provide a kind of can well the isolated electrode lug and the sealing ring of the metal shell of battery and use the Ni-MH battery of sealing circle.
A kind of sealing ring comprises circle body and step; Described circle body is cylindric, and receipts extended to form laterally after described step was shunk towards the center of described circle body opening by described circle body.
In one embodiment, the cross section of the axis of the described circle body of process of described step is arc.
In one embodiment, the cross section of the axis of the described circle body of process of described step is linear.
In one embodiment, the cross section of the axis of the described circle body of process of described step is vertical with plane, described circle body opening place.
In one embodiment, the height of described step is 0.01mm ~ 5mm.
A kind of Ni-MH battery comprises metal shell, electrode lug and sealing ring, and described sealing ring is between described metal shell and described electrode lug;
Described sealing ring comprises circle body and step; Described circle body is cylindric, and receipts extended to form laterally after described step was shunk towards the center of described circle body opening by described circle body.
In one embodiment, the cross section of the axis of the described circle body of process of described step is arc.
In one embodiment, the cross section of the axis of the described circle body of process of described step is linear.
In one embodiment, the cross section of the axis of the described circle body of process of described step is vertical with plane, described circle body opening place.
In one embodiment, the height of described step is 0.01mm ~ 5mm.
This sealing ring has towards the center of circle body opening and shrinks the step that the backward outside extends to form, when being used for Ni-MH battery, can well isolated electrode lug and metal shell, so that metal shell and the insulation of electrode lug, avoid causing battery short circuit zero electricity because electrode lug bending angle problem causes electrode lug contacting metal inner walls, cause the cell safety problem.
Description of drawings
Fig. 1 is the partial cross section figure of the Ni-MH battery of an execution mode.
Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.A lot of details have been set forth in the following description so that fully understand the utility model.But the utility model can be implemented much to be different from alternate manner described here, and those skilled in the art can be in the situation that do similar improvement without prejudice to the utility model intension, so the utility model is not subjected to the restriction of following public implementation.
The Ni-MH battery of an execution mode as shown in Figure 1 comprises sealing ring 100, metal shell 200, electrode lug 300 and positive electrode cap 400.
This sealing ring 100 has towards the center of circle body 102 openings and shrinks the step 104 that the backward outside extends to form, can well isolated electrode lug 300 and metal shell 200, so that metal shell 200 and 300 insulation of electrode lug, avoid causing battery short circuit zero electricity because electrode lug 300 bending angle problems cause electrode lug 300 contacting metal housings 200 inwalls, cause the cell safety problem.
In the present embodiment, the cross section of the axis of the process circle body 102 of step 104 is arc.The cross section is that the step 104 of arc has stronger toughness, and can be with metal shell 200 close contacts of battery, the better metal shell 200 of isolated electrode lug 300 and battery.
In other execution mode, the cross section of the axis of the process circle body 102 of step 104 is linear.This straight line can be vertical with the circle body plane of the opening, also can out of plumb.
The height of step 104 can be 0.01mm ~ 5mm.The height of step 104 is in the application that this scope can be good at adapting to the battery of all size.
This sealing ring 100 goes for multiple battery, is not limited only to as described above Ni-MH battery, for other batteries such as nickel zinc, NI-Gs, also can be suitable for.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
