Abstract
The utility model relates to a kind of tubbiness barrier film.A kind of tubbiness barrier film, comprises barrier film, negative plate retainer plate and ring; It is characterized in that: barrier film side bonding negative plate retainer plate; Negative plate retainer plate is hollow cylinder; Negative plate retainer plate two ends connect ring, and ring semicircular in shape, with negative plate retainer plate equal diameter size, tubbiness diaphragm diameter is less than negative electrode casing inner diameter 2 ~ 4mm, negative plate retainer plate height negative plate thickness 1 ~ 2mm.The utility model effectively can avoid the short circuit problem of button cell, and it is simple to have structure, is easy to the advantages such as production, is with a wide range of applications in field of batteries.
Description
Technical field
The utility model relates to a kind of tubbiness barrier film.
Background technology
Button cell volume is little, in manufacturing process, easily occurs the faults such as barrier film bends, curling, causes barrier film cannot completely cut off positive pole and negative pole completely; And cause both positive and negative polarity short circuit, thus the potential safety hazard such as cause that battery is scrapped.
Summary of the invention
The utility model, for above deficiency, provides the barrier film that a kind of structure is simple, easy to use.
The utility model solves the technical scheme that its technical problem adopts:
A kind of tubbiness barrier film, comprises barrier film, negative plate retainer plate and ring; It is characterized in that: barrier film side bonding negative plate retainer plate; Negative plate retainer plate is hollow cylinder; Negative plate retainer plate two ends connect ring, and ring semicircular in shape, with negative plate retainer plate equal diameter size, tubbiness diaphragm diameter is less than negative electrode casing inner diameter 2 ~ 4mm, negative plate retainer plate height negative plate thickness 1 ~ 2mm.
Owing to adopting said structure, so the utility model has following characteristics:
1., after placing negative plate in negative plate retainer plate, press close to negative plate below ring, to prevent negative plate from coming off, definitely avoid laboratory to prepare the generation of button cell short circuit phenomenon.
2. high negative plate thickness 1 ~ 2mm, can not cause the destruction of barrier film itself when installing battery.
3. tubbiness diaphragm diameter is less than the diameter 2 ~ 4mm of negative electrode casing innermost layer, and the internal layer of negative electrode casing can not cause extruding to barrier film.
Accompanying drawing explanation
Concrete structure of the present utility model is provided by following instance and accompanying drawing.
The schematic diagram of Fig. 1 tubbiness barrier film.
In figure, 1-barrier film; 2-negative plate retainer plate; 3-is ring
Embodiment
For summary of the invention of the present utility model, Characteristic can be understood further, hereby lift following examples, and coordinate accompanying drawing to be described in detail as follows:
A tubbiness barrier film as shown in Figure 1, comprises barrier film, negative plate retainer plate and ring; It is characterized in that: barrier film side bonding negative plate retainer plate; Negative plate retainer plate is hollow cylinder; Negative plate retainer plate top arranges semi-circular recesses; Negative plate retainer plate two ends connect ring, and ring semicircular in shape, with negative plate retainer plate equal diameter size, tubbiness diaphragm diameter is less than negative electrode casing inner diameter 2 ~ 4mm, negative plate retainer plate height negative plate thickness 1 ~ 2mm.When assembled battery and traditional building methods similar, battery bottom is supreme places positive plate, tubbiness barrier film, negative plate successively; The volume of dripped electrolyte must be controlled in the process of installing battery, make electrolyte can infiltrate this column barrier film.
Above-mentioned embodiment is exemplary, is to better enable those skilled in the art understand this patent, can not be interpreted as it is restriction this patent being comprised to scope; As long as according to this patent disclose any equivalent change done or the modification of spirit, all fall into the scope that this patent comprises.
