Specific embodiment
Below, with reference to accompanying drawing being specifically described to the large aperture dead ring and the battery that possesses the large aperture dead ring of the present invention.But, the dead ring and battery of the present invention are not limited to following specific concrete forms.
Secondary cell (hereinafter referred to as battery) possesses plain battery, the dead ring being covered in the hush panel of the plain battery and coats the heat-shrinkable T bush of the plain battery and the dead ring.Plain battery is made up of metal battery case, hush panel and the power generation element being sealed in the closed chamber formed by the battery case and hush panel.By the opening portion upper end of battery case on the insulating washer ca(u)lk to hush panel after, constitute the plain battery of closing.A dead ring is placed in the hush panel of plain battery, the dead ring plays a part of that the electrode terminal in hush panel reliably insulate with the battery case as another electrode terminal.Then, heat-shrinkable T bush is carried out to plain battery and dead ring, complete battery is constituted.
As shown in figure 1, the generally planar ring-type of dead ring (1) of the prior art, in the central portion with through hole (2), the aperture of the through hole is roughly the same with the diameter of the electrode terminal (i.e. top cover) being formed in hush panel.In this specification, such dead ring is referred to as into " small-bore dead ring ".Therefore, as shown in Figure 2, when the dead ring (1) is configured in the hush panel of plain battery (3) (4), the position of dead ring (1) is substantially limited by electrode terminal (5), and the contact surface between dead ring (1) and hush panel (4) is big, can stably place, therefore, it is not susceptible to misplace or drops in follow-up heat-shrinkable T bush operation.
However, as previously described, because the diversity of customer requirement, must expand the aperture of through hole sometimes so that a part for hush panel is exposed from through hole.In this specification, such dead ring is referred to as into " large aperture dead ring ".The present invention is precisely in order to tackling this demand to the battery for possessing large aperture dead ring and making.
When wide-aperture dead ring (1) using flat annular as shown in Figure 3, due to dead ring (1) it is all less by being limited in vertical direction, horizontal direction, and diminish (referring to Fig. 4) with the contact area of the hush panel (4) of plain battery (3), therefore it is easy to be moved in the horizontal direction and misplace, or even falls down.In addition, in the heat-shrinkable T bush operation for subsequently carrying out, due to the touching of part of appliance etc., also easily making dead ring drop, the disappearance of dead ring in resultant battery is caused.
In order to increase the stability of dead ring, it is sometimes desirable to adopt bonding agent between dead ring and hush panel, so, although dead ring becomes to be difficult to drop, but wastes time and energy in operation, and therewith it may happen that bonding agent overflow and the problems such as pollute,
In order to solve the above problems, the basic ideas of the present inventors are to transform the large aperture dead ring of flat annular as stereochemical structure, by arranging the side wall perpendicular to principal plane, can limit dead ring moving horizontally in hush panel, and prevent dropping for dead ring.
Fig. 5 represents the large aperture dead ring of an embodiment of the invention, it is characterized in that, dead ring (1) is stereochemical structure, possess principal plane (1a) and the side wall (1b) perpendicular to principal plane, principal plane (1a) is flat annular of the central authorities with through hole (2), in the present embodiment, side wall (1b) starts side's extension vertically downward and is formed from the inner periphery (i.e. the periphery of through hole) of principal plane (1a).Need exist for explanation, in this specification " on ", D score direction be defined in relation to for plain battery, the side with hush panel of plain battery is top, and its opposition side is lower section (i.e. top in Fig. 5).
Fig. 6 represents several variations of the large aperture dead ring shown in Fig. 5.As can be seen that side wall (1b) can be successively formed in the inner periphery of principal plane (1a), it is also possible to be intermittently formed.
Fig. 7 is the longitudinal sectional drawing for representing the battery with the large aperture dead ring shown in Fig. 5.
As shown in Figure 7, when dead ring (1) is assembled on plain battery, the principal plane (1a) of dead ring (1) is covered in the hush panel of plain battery (3) (4), but because the aperture of through hole (2) is more than the diameter of electrode terminal (5), so that being formed at the side wall (1b) of the inner periphery of principal plane (1a) away from electrode terminal (5), a part (parts in central authorities) for hush panel (4) is exposed from through hole (2).
In the present invention, so-called " large aperture dead ring ", refers to leave certain gap between the inner periphery of the ring-type principal plane of dead ring (1) and electrode terminal (5), is also referred to as sometimes " dead ring ".It is preferred that the periphery of inner periphery and electrode terminal (5) is at a distance of more than 2mm, more preferably at a distance of more than 3mm.The aperture of through hole (2) is preferably 1.2～4 times of the diameter of electrode terminal (5), more preferably 1.3～3 times, more preferably 1.4～2 times.
Due to leaving certain gap between the inner periphery and electrode terminal (5) of dead ring (1), therefore the principal plane (1a) of dead ring (1) easily produces the movement of horizontal direction in hush panel, it is not easy to be positioned.In the present invention, side wall (1b) is arranged by the inner periphery in principal plane (1a), can be solved the above problems to a certain extent.
Specifically, as shown in Figure 7, the battery shell side wall of plain battery (3) is formed with boss (8) by ca(u)lk with hush panel in the most peripheral of hush panel, therefore, side wall (1b) movement in the horizontal direction is limited between electrode terminal (5) and boss (8).Therefore, dead ring (1) movement in the horizontal direction is also restrained, is not susceptible to misplace or drops.
In above-mentioned embodiment, boss (8) is the projection for being carried out ca(u)lk sealing and being formed by battery shell side wall and hush panel, but the protrusion for being also not necessarily limited to this, or being formed in hush panel by techniques such as compression moldings.In this case, side wall (1b) movement in the horizontal direction can be limited between electrode terminal (5) and the projection, can also be limited between above-mentioned projection and the protrusion, as a result, greatly reducing dead ring dislocation or the generation dropped.
Additionally, after dead ring is assembled in the hush panel of plain battery, needing to carry out heat-shrinkable T bush.Heat-shrinkable T bush is the operation for being allowed to integration from the side wall coated insulation ring and battery shell side wall of plain battery using resin film, after the completion of heat-shrinkable T bush, due to the aperture of the through hole (2) of dead ring (1) it is larger, although can't see the presence of dead ring (1) from battery outside and surface, the presence of side wall (1b) can be observed from the oblique upper of through hole (2).Therefore, in the visual inspection before battery dispatches from the factory, missing inspection can positively be prevented.
Fig. 8 represents the large aperture dead ring of another embodiment of the invention.It is that side wall (1b) is to start to extend vertically downward from the neighboring of principal plane (1a) and formed with the difference of the dead ring of Fig. 5.
Fig. 9 is the longitudinal sectional drawing for representing the battery with the dead ring shown in Fig. 8.
As shown in Figure 9, when side wall (1b) is formed at the neighboring of principal plane (1a), side wall (1b) is covered on the battery shell side wall of plain battery (3), so that dead ring (1) movement in the horizontal direction is restricted, it is not susceptible to misplace or drops.
Can be with the size of the neighboring of the principal plane (1a) of reasonable design dead ring (1), so that side wall (1b) just coats the battery shell side wall of plain battery (3), now, dead ring (1) is not accurately positioned only in horizontal direction, and, due to the frictional force between side wall (1b) and battery shell side wall so that dead ring is also restrained in the movement of vertical direction, more difficult to drop.
In the present invention, no matter side wall (1b) is formed at inner periphery or the neighboring of principal plane (1a), because side wall is formed on the direction of the principal plane of dead ring, therefore, by restriction effect of the electrode terminal and projection or battery shell side wall in hush panel to sidewall locations, so that the dead ring can not be moved freely through in the horizontal direction, the possibility that dead ring in battery assembly process occurs to misplace in the horizontal direction is greatly reduced.
Further, when side wall (1b) to be formed at the inner periphery of principal plane (1a), when being visually inspected, easily whether there is from the oblique upper observation side wall of through hole, therefore the possibility of battery missing inspection can be substantially reduced.
And when side wall (1b) to be formed at the neighboring of principal plane (1a), dead ring (1) can not be accurately positioned only in horizontal direction, and, due to the frictional force between side wall (1b) and battery shell side wall, so that dead ring is also restrained in the movement of vertical direction, it is more difficult to drop.
Figure 10 represents the wide-aperture dead ring of further embodiment of the present invention, it is characterised in that further have snap fastener on the wall of side.By arranging snap fastener on side wall (1b), the clamping force of vertical direction can be produced with plain battery so that dead ring is not easy in vertical direction movement, is firmly secured in the hush panel of plain battery.
