Technical field
The utility model relates to the structure of capacitor, particularly a kind of cylindrical ultracapacitor utmost point group.
Background technology
Super constant volume device is widely used in the occasion that instantaneous large-current discharges and recharges, in the majority in the ultracapacitor market more than 100F at present with cylindrical ultracapacitor, and most ultracapacitors adopt utmost point group two ends multiple spot afflux technology, just adopt utmost point group two ends to reserve the collector aluminium foil, in the post-production process, weld to obtain the structure of multiple spot afflux with the aluminium foil shaping and with the leads component that confluxes, this structure helps reducing ultracapacitor ESR (equivalent series internal resistance) on the one hand, can guarantee the stability of utmost point group internal structure on the other hand as far as possible.
Carrying out both positive and negative polarity when drawing; utmost point group top is welded as an electrode (positive pole or negative pole one of them) with the electrode leads to client of an isolation on the lid; utmost point group bottom forms another electrode (being opposite polarity with the electrode of isolating on the lid) with the shell welding, and we pay particular attention to the insulation protection of utmost point group apex electrode extension with housing sidewall in a such structure.Our employings spraying insulating coating on the area of the corresponding utmost point group of shell sidewall top afflux part carries out insulation processing in traditional supercapacitor structures, this insulation processing mode comparatively validate in use causes short circuit to cause security incident in controlling easily, and course of processing more complicated, cost is than higher.So ultracapacitor utmost point group top insulation system is very important for ultracapacitor safety and production and processing.
Summary of the invention
It is simple, stable and reliable for performance that the purpose of this utility model provides a kind of technology, uses the ultracapacitor utmost point group of peace usefulness.
The utility model for achieving the above object, the technical scheme that adopts is a kind of super electrode capacitor utmost point group, comprise pole, pole is a cylinder that is wound into by aluminium foil, dielectric substrate and dielectric film, and its innovative point is: the two ends of pole outside also are provided with the insulating tape that is intertwined with pole.
Described insulating tape is on a face of polymeric membrane, part has the glue-line of covering, the width of insulating tape is 4～20mm, it is 3～15mm that single face covers glue-line glue face width degree, the thickness of polymeric membrane is 0.01～0.03mm, covering bondline thickness is 0.01～0.02mm, and integral insulation adhesive tape thickness is 0.02～0.04mm.
Described insulating tape has the glue that do not cover that covers the glue-line one side and partly makes progress, and is positioned at the two ends of pole, twines 375 °～410 ° on pole, and the insulating tape edge stretches out 1～5mm on the pole end face.
Ultracapacitor utmost point group of the present utility model is because the insulation system on utmost point group top uses single face part area to cover the insulating tape of glue when utmost point group is reeled, directly be wrapped in the ad-hoc location at utmost point group two ends, replaced traditional capacitor casing sidewall coatings to carry out insulation between utmost point group and the housing sidewall, simplified the insulation processing between top, utmost point group two ends afflux part and the housing sidewall, improved the controllability of insulating barrier, increase the qualification rate of capacitor finished product, improved the security performance of capacitor product.
Description of drawings
Fig. 1 is the structural representation of the utility model ultracapacitor utmost point group.
Embodiment
The embodiment that provides below in conjunction with accompanying drawing describes in further detail the utility model.
Referring to Fig. 1, a kind of super electrode capacitor utmost point group comprises pole 1, and pole 1 is a cylinder that is wound into by aluminium foil 1-1, dielectric substrate 1-2 and dielectric film 1-3, and its innovative point is: the two ends of pole 1 outside also are provided with the insulating tape 2 that is intertwined with pole 1.The traditional capacitor casing sidewall coatings of ad-hoc location replacement of utilizing insulating tape 2 directly to be wrapped in pole 1 two ends when pole 1 is reeled is carried out the insulation between utmost point group and the housing sidewall, simplified the insulation processing steps, improved the controllability of insulation, reduce the capacitor production cost, improved the quality and the security performance of capacitor.
Referring to Fig. 2, in order further to improve the performance of utmost point group and the security performance of use, reduce cost, described insulating tape 2 is on a face of polymeric membrane, and part has the glue-line of covering 2-1, and the width of insulating tape 2 is 4～20mm, it is 3～15mm that single face covers glue-line glue face width degree, the thickness of polymeric membrane is 0.01～0.03mm, and covering bondline thickness is 0.01～0.02mm, and integral insulation adhesive tape thickness is 0.02～0.04mm.
Described insulating tape 2 has the glue that do not cover that covers glue-line 2-1 one side and partly makes progress, and is positioned at the two ends of pole 1, twines 375 °～410 ° on pole 1, and insulating tape 2 edges stretch out 1～5mm on pole 1 end face.
Referring to Fig. 1, the pole 1 of a kind of cylindrical ultracapacitor utmost point group of the present utility model adopts the part area to cover the insulating tape 2 and aluminium foil 1-1 of glue, electrolyte 1-2, dielectric film 1-3 reels together, after finishing, promptly at the two ends of pole 1, need the aluminium foil 1-1 of insulated part to be wound with insulating tape 2 outward, insulating tape 2 partly covers glue for PET or PTFE or PAI polymeric membrane carry out single face, the width of insulating tape 2 is 4～20mm, single face covers glue, the sticky surface width is 3～15mm, polymeric membrane thickness is 0.01～0.03mm, and bondline thickness is 0.01～0.02mm, integral insulation adhesive tape thickness 0.02～0.05mm.Insulating tape 2 has the glue that do not cover that covers glue-line 2-1 one side and partly makes progress, and is positioned at the two ends of pole 1, twines 375 °～410 ° on pole 1, and insulating tape 2 edges stretch out 1～5mm on pole 1 end face.The utmost point group of having twined insulating tape 2 can directly be used in the operation that ultracapacitor is produced; can not need to carry out any insulation protection handles again; this has just reduced the capacitor production stage and has simplified technology; and the ultracapacitor utmost point group that has an insulating tape 2 in use; the insulation protection stable performance, reliably, particularly in voltage stabilizing, hot case is in the vibration processes; because the stable insulation of utmost point group is reliable, improved the fail safe that capacitor uses greatly.
