Abstract
The present invention discloses sealing technology of a battery terminal and a structure thereof, which relates to sealing technology of a battery terminal and a structure thereof, particularly to sealing technology of a storage battery terminal and a structure thereof. The technology comprises the following steps: A. a plastic body is formed on a battery terminal in an injection molding way; B. the cover body of a battery is combined with the main body of the battery in a heat sealing way, and simultaneously, the plastic body on the battery terminal is combined with the cover body of the battery in a thermal sealing way; C. a sealing ring is sheathed on a battery terminal, and the sealing ring is pressed by a fastening piece. The present invention has reliable sealing effect, and can realize mechanization flow operation to improve production efficiency, and shorten production periods.
Description
Technical field the present invention relates to the constitutional detail of the nonactive parts of storage battery, relates in particular to the encapsulating method and the structure of accumulator terminal.
The terminal sealing technology of background technology prior art storage battery has following several mode: 1. epoxy sealing, its shortcoming is to need long curing time, at room temperature be that 24 hours, hot setting are also wanted 2 hours, production can't realize the automation continuous productive process; 2. a lead cover is inlayed in plumbous cover sealing on battery big cover, thereby the lead terminal post of battery utmost point group is molten into one realization sealing with plumbous cover.Shortcoming is, described plumbous cover is stamped different thermal coefficient of expansions greatly with plastics, battery in use, plumbous overlapping can occur separating with big lid plastics, causes inside battery acid solution seepage.
The summary of the invention the technical problem to be solved in the present invention is to avoid above-mentioned the deficiencies in the prior art part and the encapsulating method and the structure that propose a kind of sealing effectiveness reliable battery terminal.
The present invention solve the technical problem can be by realizing by the following technical solutions.Propose a kind of encapsulating method of battery terminal, may further comprise the steps: A. forms a plastic body at the position, stage casing of battery terminal by Shooting Technique; B. cover big lid, making the periphery of big lid and the peripheral fusion of housing with hot sealing process is one, and the plastic body end face on the described battery terminal also combines together with the lower end heat of big lid corresponding site; C. stretch out in the groove of big lid corresponding site on described battery terminal top, down is inserted in sealing ring to bottom portion of groove from the top of battery terminal, compresses the sealing circle with securing member again.
The present invention solve the technical problem can also be by coming further realization by the following technical solutions, design and produce a kind of hermetically-sealed construction of battery terminal, comprise battery container, battery big cover, battery terminal, especially, the position, stage casing of battery terminal is fixed with plastic body, and this plastic body and battery big cover are tightly connected, and battery big cover is provided with sealed groove above its terminal hole, be placed with sealing ring in the sealed groove, and by securing member with its compacting.
Compare with prior art, outstanding advantage of the present invention is: sealing effectiveness is reliable, can realize mechanized continuous productive process, thereby enhance productivity, and shortens the production cycle.
Description of drawings Fig. 1 is the schematic diagram of one of most preferred embodiment of the present invention;
Fig. 2 is the schematic diagram that is injected with the battery terminal 3 of plastic body 31 among Fig. 1 embodiment;
Fig. 3 is the schematic diagram of another most preferred embodiment of the present invention.
The invention will be further described below in conjunction with each most preferred embodiment shown in the accompanying drawing for embodiment: as shown in Figure 1, a kind of encapsulating method of battery terminal may further comprise the steps:
A. at the position, stage casing of battery terminal 3, form a plastic body 31 by Shooting Technique;
B. cover big lid 2, making the periphery of big lid 2 and the peripheral fusion of housing 1 with hot sealing process is one, described battery-end
C. stretch out in the groove 22 of big lid 2 corresponding sites on described battery terminal 3 tops, past from the top of battery terminal 3
Under be inserted in sealing ring 4 to groove 22 bottoms, compress sealing circle 4 with securing member 5 again.So, battery terminal 3 is carried out two seals, improved sealing effectiveness.
When implementing described step C, be to be inserted in from the top of described battery terminal 3, and rotatably compress described sealing ring 4 by the internal thread 24 on terminal hole 21 tops with external screw thread nut 51.The material of sealing ring 4 used herein is a rubber, and the material of used securing member 5 is plastics.Used encapsulant must be acidproof or alkaline-resisting, to prevent acid, alkali lye sealing ring 4 corrosion reduced sealing effectiveness.
When implementing described steps A, used injected plastics material is a thermoplastics, and they are: acrylonitrile-butadiene-styrene (ABS) copolymer, or polypropylene, or polyvinyl chloride, or Merlon.
The hermetically-sealed construction of battery terminal of the present invention, as shown in Figure 1 and Figure 2, comprise battery container 1, battery big cover 2, battery terminal 3, especially, the position, stage casing of battery terminal 3 is fixed with plastic body 31, and this plastic body 31 is tightly connected with battery big cover 2, and battery big cover 2 is provided with sealed groove 22 above its terminal hole 21, be placed with sealing ring 4 in the sealed groove 22, and by securing member 5 with its compacting.So realized the sealing of two roads, thereby made the battery terminal sealing reliable.
As shown in Figure 1, securing member 5 is an external screw thread nut 51, and the topmost position of terminal hole 21 correspondingly is provided with internal thread 24.As shown in Figure 3, be provided with an expansion loop 6 between sealing ring 4 and the securing member 5, further strengthened sealing effectiveness.
Compare with prior art, the inventive method has shortened the production cycle of battery, has improved labor productivity.As the production technology of lead acid accumulator, traditional handicraft is:
Utmost point assembling shell → utmost point group series connection → notes fluid sealant → capping → curing → weldering terminal → notes terminal sealing glue → curing → notes acid → charging or utmost point assembling shell → utmost point group series connection → notes fluid sealant → capping → curing → pole overlap the acid → charging of freezing → annotate with lead.
Production technology after employing the inventive method is:
Utmost point assembling shell → utmost point group series connection → lid shell seals → adds sealing ring and fastening → notes acid → charging.
Both compare, the production technology after employing the inventive method, and operation reduces, and the production cycle shortens, and operating efficiency improves. Also strengthened simultaneously sealing effectiveness.
