External substance enters inside battery.In this way, solving cylinder directly contacts the situation hair for being easy to cause battery short circuit with coping plate
Give birth to and need the gap between the outer peripheral sidewall and post holes to cylinder to be filled, prevent conducting block from producing in use
The problem of twisting.
Embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only explaining
The utility model, is not used to limit the utility model.
It is described in detail below in conjunction with realization of the specific embodiment to the utility model.
The same or similar label correspond to the same or similar components in the attached drawing of the present embodiment;In retouching for the utility model
In stating, it is to be understood that if it is based on attached drawing to have the orientation of the instructions such as term " on ", " under ", "left", "right" or position relationship
Shown orientation or position relationship, are for only for ease of description the utility model and simplify description, rather than indicate or imply institute
The device or element of finger must have specific orientation, with specific azimuth configuration and operation, therefore position is closed described in attached drawing
The term of system is only for illustration, it is impossible to the limitation to this patent is interpreted as, for those of ordinary skill in the art
Speech, can understand the concrete meaning of above-mentioned term as the case may be.
It is preferred embodiment provided by the utility model with reference to shown in Fig. 1~2.
The dead ring for the battery that the utility model passes through, directly contacts for solving cylinder with coping plate and is easy to cause battery
The situation of short circuit occurs and the gap between the outer peripheral sidewall and post holes of cylinder is not sealed, and external substance enters in battery
Portion, the problem of being unfavorable for the use of battery.The dead ring can be applied in the various batteries for using dead ring, be not limited only to this reality
Apply example.
The dead ring of battery, including ring body 11, the ring body 11 is horizontally disposed, is provided with ring body 11 and leads to for what cylinder passed through
Hole 12, the shape of the through hole 12 are mutually agreed with the shape of cylinder, so that through hole 12 coordinates even closer with cylinder.In ring
The lower surface of body 11 is provided with the parcel circle 13 for wrapping up cylinder, and parcel circle 13 is arranged around the periphery of through hole 12, and is wrapped up
Circle 13 extends downward.According to actual needs, the extending direction of parcel circle 13 can be adjusted according to the shape of the outer peripheral sidewall of cylinder
It is whole.
The dead ring of the battery of above-mentioned offer, by setting through hole 12 in ring body 11, the lower surface of ring body 11 is provided with
Parcel circle 13 around 12 periphery of through hole, in assembling process, after cylinder reaches precalculated position through coping plate, by dead ring
Installed in reserved location, the top of cylinder is embedded into through hole 12 at this time, lower part be wrapped circle 13 it is fully wrapped around live, avoid column
Body is directly contacted with coping plate.In addition, the parcel circle 13 extended downward is filled in the outer peripheral sidewall of cylinder and the inner side of post holes
In gap between wall, there is fixation to cylinder, prevent the twisting of cylinder, there is anti-torsion.In addition, parcel circle
13 are filled in the gap between cylinder and coping plate, have Packed effect, can enter inside battery to avoid external substance.This
Sample, solves cylinder and is directly contacted with coping plate and be easy to cause the situation of battery short circuit and occur and need outer circumferential side to cylinder
Gap between wall and post holes is filled, the problem of preventing conducting block from producing twisting in use.
For the ease of the installation of battery, the thickness of ring body 11 everywhere is arranged to identical, when ring body 11 is placed in predetermined position
When putting, its lower surface is abutted with the upper surface of coping plate, its upper surface is abutted with the lower surface of riveting sheet, and thickness is identical everywhere
Ring body 11 causes cooperation of the ring body 11 with riveting sheet and coping plate with good, the assembling for battery of being more convenient for.In the present embodiment, ring body 11
In class ellipse, according to actual needs, ring body 11 also may be configured as other shapes.
In the present embodiment, smoothly transit between the madial wall of parcel circle 13 and the madial wall of through hole 12.In fact, parcel circle
The shape size of 13 inner wall is identical with the shape size of the madial wall of through hole 12, smoothly transits between the two, so has
Beneficial to cylinder smoothly through parcel circle 13 and through hole 12 so that battery can be rapidly performed by assembling.
In the present embodiment, the upper surface of ring body 11 is provided with bulge loop 14, and through hole 12 is arranged on 14 area encompassed of bulge loop
It is interior.After in cylinder and dead ring, installation is complete, riveting sheet and cylinder are attached, riveting sheet is embedded into bulge loop 14 and ring at this time
In the region that body 11 is formed, so that the connection of riveting sheet and cylinder is more firm, and bulge loop 14 has guarantor to riveting sheet
Shield acts on.
Specifically, bulge loop 14 is arranged along the neighboring of ring body 11.In fact, bulge loop 14 is by the neighboring of ring body 11
Convex to form upward, in this way, in the case where 11 area of ring body is fixed so that the region inside bulge loop 14 is maximum so that pole
It can be connected with the riveting sheet of area bigger, it is convenient to extraneous power supply.
In order to riveting sheet preferably coordinate, bulge loop 14 is arranged to extend upward.In this way, after riveting sheet is embedded in, riveting
The outer peripheral sidewall of contact pin and the inner side of bulge loop 14 are mutually agreed with, cooperation it is more preferable.In addition, the height of bulge loop 14 and the thickness of riveting sheet
It is identical.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
