Abstract

The utility model relates to a terminal holder for an accumulator, which is arranged on the battery cover. The utility model has a concave part, the bottom end of the terminal holder is provided with a perforation through which an electrode bar can be penetrated, an annular slot is concavely arranged on the tip edge of the perforation, a terminal is fixedly arranged on the top of the electrode bar, resin used for quickly sticking the annular slot and the electrode bar into integration is filled at the periphery of the electrode bar in the annular slot, the gap between the annular slot and the electrode bar is completely stuffed and sealed by the resin, colloid is filled into the terminal holder, the lower end of the terminal is buried and positioned, and the downward leakage of the colloid through the perforation is prevented.

Description

Terminal holder for accumulator

The utility model relates to a kind of accumulator terminal seat, particularly a kind ofly wears terminal base potting compound body region in rod extremely, has the accumulator terminal seat that prevents to leak preferable effect.

As Fig. 1, shown in 2, storage battery comprised a battery cap 11 and an accumulator body 12 of establishing with the corresponding lid of battery cap in the past, be provided with the pole plate group 13 of positive electrode or negative electrode in the accumulator body 12, accumulator body 12 tops are installed with an extremely rod 14, extremely rod 14 up passes battery cap 11(and is located at the corner usually) perforation 151 of offering of terminal base 15 bottoms of inner recess shape, in order to connect easily, extremely excellent 14 tops set firmly a upper end and protrude out the terminal 16 of terminal base 15 tops and extremely rod grafting, extremely rod 14 and terminal 16 are set in integral end stroma 15, must have sealing and the extremely rod 14 and the steadiness and the insulating properties of terminal 16, claim red-black glue so must in terminal base 15 depression positions, pour into the colloid 17(paddy of forming by epoxy resin and curing agent, usually positive electrode uses red glue, negative electrode uses black glue to show difference), with landfill location, terminal 16 lower end, so terminal 16 just can bear bigger sleeve power, does not excessively rock the problem that causes loose contact and do not have.During colloid 17 perfusion just is the viscous fluid state, must solidify through becoming dry gradually after long-time fixing effect just can be arranged, in order to prevent that colloid 17 from infiltrating battery body 12 inside via the air gap leakage of above-mentioned extremely excellent 14 traversing through end stromas 15 bottoms when the fluid state, perforation 151 top edge of terminal base 15 were concaved with an annular groove 152 in the past, and when extremely excellent 14 traversing through end stromas 15, in annular groove 152, fill in the round ring 153 made from rubber of packing into earlier, round ring 153 rings are restrainted in the periphery of rod 14 extremely, prevent that the colloid 17 that poured into afterwards from infiltrating in the battery bodies 12.

The annular groove 152 that above-mentioned 15 bottom perforateds of terminal base in the past, 151 apical margins are arranged with, fill in round ring 153, prevent that colloid 17 leakages from entering in the design of accumulator body 12, when filling in round ring 153 in the annular groove 152, must round ring 153 be extruded with the instrument of taper, make round ring 153 each position all positively enter in the annular groove 152, and be tight against the anti-leak result of annular groove 152 bottom competence exertion the bests, not only when assembling, bother, and easily because assembling does not produce the phenomenon of leakage really and still.

The purpose of this utility model is to provide a kind of anti-leak result good and process accumulator terminal simply and easily.

Of the present utility model being characterised in that: this terminal base has a depressed part, and be arranged on the battery cap, place, terminal base depressed part bottom offers the extremely excellent perforation that passes of a confession, the perforation apical margin is arranged with an annular groove, extremely excellent periphery in the annular groove is filled with annular groove and the rod extremely resin of cementation one fast, makes annular groove and the space between rod extremely pour into colloid in the terminal base fully by the resin packing and sealing, with terminal lower end landfill location, prevent that colloid from up leaking through perforation.

Below by most preferred embodiment and accompanying drawing accumulator terminal seat of the present utility model is elaborated, in the accompanying drawing:

Fig. 1 is that the accumulator terminal seat was positioned at the top view of battery cap position in the past.

Fig. 2 is that the part of accumulator terminal seat is in the past amplified cut-away view.

Fig. 3 is the generalized section of the utility model preferred embodiment.

As shown in Figure 3, storage battery of the present utility model and above-mentioned in the past the structure of storage battery are roughly the same, of the present utility model being characterised in that: perforation 21 apical margins of accumulator terminal seat 2 bottoms are concaved with a taper annular groove 22 wide at the top and narrow at the bottom, extremely rod 3 perforation 21 that stretch through out, extremely injection has resin 23 dried soon, mobile difference on a small quantity on the excellent 3 peripheral place taper annular grooves 22, this resin 23 can use the resin of a kind of code name X-N6, and its composition comprises host one denaturation loop epoxy resins and curing agent one sex change amine.Because taper annular groove 22 is shape with wide top and narrow bottom, so when resin 23 is filled on taper annular groove 22, can assemble toward the taper bottom of annular groove 22 naturally, and, resin 23 adds the fashionable shape and have the characteristic of very fast curing of being in a liquid state, therefore not only resin 23 can ooze poly-annular groove 22 bottoms that fill in by stream, and can soon taper annular groove 22 and extremely excellent 3 cementations be integral, make therebetween space fully by packing and sealing, and few because of amount of fill, gravity is little, itself is mobile poor, can not ooze down yet, when perfusion colloid 4 in terminal base 2 depression positions, just can prevent that colloid 4 leakages from entering in the battery body 5.

Accumulator terminal seat of the present utility model has following effect:

Present embodiment leaks the setting that enters the resin 23 in the accumulator body 5 to block colloid 4, utilize taper annular groove 22 to assemble naturally toward the bottom for resin 23, not only reach the effect of even packing and sealing, can be as produced the phenomenon of leaking really because of round ring assembling easily in the terminal base in the past, and resin of the present utility model 23 perfusions are convenient, also than the structure assembling that must utilize sticker to be extruded again behind the round ring of the suit in the past material-saving that saves time.

The cross sectional shape of the annular groove 22 in the present embodiment, if be designed to square-section as in the past annular groove 152, can load resin 23 is equally sealed, but, the consumption of resin 23 is wasted in the square-section, and spontaneous current is poly-and effect that evenly load is also poor than taper cross section, and it is different that square-section sealing effect and taper cross section there is no, but with above-mentioned taper cross section ideal comparatively.

Take a broad view of above-mentionedly, the utility model is good and process accumulator terminal seat simply and easily for a kind of anti-leak result really.

Claims

1, a kind of accumulator terminal seat has a depressed part, and this depressed part bottom offers a perforation, and the perforation apical margin forms the annular groove of a depression, wears an extremely rod in the perforation, and extremely rod passes this terminal base and annular groove, it is characterized in that:

It is wide at the top and narrow at the bottom cone-shaped that described annular groove is, and the extremely excellent periphery in the annular groove is filled with quick-setting resin.
