And general terminal structure commonly used, mostly on vertical component effect 22, establish a perforation, during connection, then utilize a screw 40 to pass lead 30 terminal clasps 31 (or by the directly curved coiled loop shaped of the heart yearn of lead 30) by a side, pass perforation on the vertical component effect 22 again, be screwed into screw 40 with a nut by opposite side again and screwed tight sealedly, lead 30 is firmly connected in battery.

Yet, according to above-mentioned common structure, in the operation that connects lead 30, after screw wore each member, all must cooperate the complete spiral shell of ability solid with it with a nut again, and the space that is limited to general groove 11 is little, except that being difficult for holding nut to be screwed into the screw, when screwing togather operation, also wayward nut, in case nut rotates with screw and can't lock, cause assembling to go up inconvenience.

And at above-mentioned shortcoming, existing on the market a kind of improvement design, promptly at the perforation outer rim place of vertical component effect 22 medial surfaces, be convexly equipped with the bilateral lug of an inverse, but make the proper holding of hexagonal (hexagon)nut in this inverse lug, form a kind of contained side anti-slip effect, when screwing tight, rotate with screw in order to avoid nut; And creator of the present utility model also once did different improvement designs, be on the medial surface of perforation on this vertical component effect 22 (i.e. the side that locks for nut), utilize the punch forming technology and straight forming one interior hexagonal shrinkage pool, part shade for hexagonal (hexagon)nut can pack in this interior angle shrinkage pool, also can form a kind of anti-slip effect, when screwing tight, cause rotation to avoid nut; And according to forming technique, this " interior hexagonal shrinkage pool " structural design is identical with above-mentioned known " inverse lug " design, but to use material, because of having increased bilateral lug, make " interior hexagonal shrinkage pool " design save material than " inverse lug " design, promote and have effect, so this creator has also applied for Taiwan patent (case number 090200434 " improved terminal structure of storage battery "), only this creator keeps on improving, and designs terminal of the present utility model again and improves design again.

The purpose of this utility model provides a kind of terminal structure of simplifying, and does not need nut but can simple and easy spiral shell to live the improved accumulator terminal of lead admittedly.

For this reason, the purpose of this utility model can realize by following mode: a kind of improved accumulator terminal, this terminal is a L shaped sheet metal, wherein, L shaped horizontal part is provided with a perforation, be in the inner groovy that is embedded on the battery case and be connected with the electrode of inside, L shaped vertical component effect is outside vertically being convexly set in, which is provided with a fixing hole, the confession screw passes this fixing hole and lead is connected on the vertical component effect, it is characterized in that: this fixing hole is to be shaped to a screw with flange, and it is directly to stamp out a perforation with flange on the sheet metal of former terminal, in the perforation and attack and be shaped on internal thread.

Clearly, the utility model mainly is on the vertical component effect lamellar body of former L type terminal, the perforation that has flange in this direct punch forming one in former punch position place, and processing forms screw structure with internal thread, but ease of Use is screwed togather, and do not need nut, and can live lead admittedly by firm spiral shell with single screw.

For enabling further to understand feature of the present utility model, conjunction with figs. is described in detail as follows now:

The simple declaration of accompanying drawing

Fig. 1 is a use schematic diagram of the present utility model.

Fig. 2 is an assembling schematic diagram of the present utility model.

Fig. 3 is the utility model one side sectional view.

Fig. 4 is another user mode schematic diagram of the utility model.

Refer again to Fig. 1 to shown in Figure 3, terminal 20 of the present utility model is L shaped sheet metals, on the whole shape is identical with general known person for it, and its main difference point, that is principal character of the present utility model is to be: the vertical component effect 22 of this L shaped terminal 20, on former punch position, be provided with a screw 222 with flange 221, it is when making this L shaped terminal 20, utilize stamping technology and directly on sheet metal moulding one have the perforation of flange 221, and in perforation, change the system of attacking again with internal thread, making becomes a screw 222 with longer spiral surface, to replace original known perforation; During use, not only can the single screw 40 of a mat and simple and easy screwing togather, and because of screw 222 spiral surface length are enough, what can make screw 40 screws togather the enhancement steadiness.

Screw 40 can be screwed into from the either side of screw 222 again, as shown in Figure 4, screw 40 is screwed into the direction of screw 222 with shown in Figure 3 opposite, by this, can make the groove 11 on body 10 shells and the design of inner groovy 12, comprise shape, size and location etc., all unrestricted than the dust head, help the design variation of battery case.

Again because the growth of screw 222 spiral surfaces is by means of this flange 221 fully, and this flange 221 is to utilize these L shaped terminal 20 sheet metals fully, in the punching press processing procedure, with the thick extruding backward of its punching meat and elongation moulding need not increase the sheet material of former L shaped terminal 20; And the waste material that when the punching moulding, produced of known perforation, the utility model can be avoided it.

Because structure-improved of the present utility model is different from known person, have following advantage so make to go up or use:

(1) the utility model directly is screwed together in screw 40 on the screw 222, does not need nut to be used, make connect lead 30 to screw togather operation comparatively easy.

(2) the utility model is to prolong with former L shaped terminal 20 employed sheet metals, need not change the size of virgin metal sheet, or otherwise designed.

(3) screw 222 of the present utility model utilizes flange 221 and increases spiral surface length, the spiral shell tenacity in the time of can effectively promoting lead 30 connections.

(4) unequal because of the length of the vertical component effect 22 of L shaped terminal 20 and horizontal part 21, making L shaped terminal 20 is not the balance component of a symmetry, can use vibration location feeding mechanical for automation feeding and processing operation, helps automation and mass manufacture process.

In sum, the technological means that the utility model is quoted is solid non-difficult, but does not see have identical person to disclose formerly in the technical field of accumulator terminal structure, and member simplifies the use effect that can realize former expection again really, so propose patent application.
