Abstract
The utility model discloses a terminal of a storage battery. The terminal comprises a lead sheath (1) and a copper core (2), wherein a slot (2.1) is formed on the copper core (2); and the copper core (2) is cylindrical and is fixed in the lead sheath (1). The terminal of the storage battery can save material; the copper core is combined with the lead sheath firmly; and the contact resistance is low.
Description
Technical field
The utility model relates to the battery technology field, relates to a kind of terminal of storage battery or rather.
Background technology
Storage battery is that a kind of electrode is mainly by lead and oxide thereof are processed, electrolyte is sulfuric acid solution storage battery.Storage battery comprises battery case, battery cover, pole plate, electrolyte and terminal.Described pole plate is installed in the described battery case; Described lid is placed on the described battery case; Be filled with described electrolyte in the described battery case, described terminal runs through battery cover and is connected with described pole plate, seals through fluid sealant between described terminal and the battery cover.See also shown in Figure 1ly, the terminal of storage battery comprises plumbous cover 1 ' and copper core 2 ', and described plumbous cover 1 ' and copper core 2 ' are through moulding by casting, and described copper core 2 ' is provided with and is used for the slot 2.1 ' that external splicing ear inserts.The terminal of the storage battery of prior art is that notch cuttype is cylindric, and small column 2.2 ' is cast in the described plumbous cover 1 ', and big column 2.3 ' reveals to be put outside lead cover 1 '.There is following defective in the storage battery of this kind prior art: put outside the lead cover because big column reveals, make copper product waste; Again owing to small column is cast in the plumbous cover; The small column surface is more smooth, and grown service time, is easy to generate the gap between copper core and the plumbous cover and loose contact when causing using; And the contact area of small column and plumbous cover is less; Therefore contact resistance is bigger in the process of using, and the heating of terminal place is expanded and destroys the sealing effectiveness of the fluid sealant between terminal and the battery cover, occurs the phenomenon that the terminal place spills electrolyte then.
Prior art: 1 ', plumbous cover, 2 ', the copper core, 2.1 ', slot, 2.2 ', small column, 2.3 ', big column.
The utility model: 1, plumbous cover, 2, the copper core, 2.1, slot, 2.2, radial groove.
The utility model content
The technical problem that the utility model will solve is, provides a kind of can the saving between material, copper core and the plumbous cover to combine the terminal firm and storage battery that contact resistance is little.
The technical solution of the utility model is, a kind of terminal with storage battery of following structure is provided, and comprises plumbous cover and copper core, and described copper core is provided with slot, and described copper core is cylindric, and described copper core is fixed in the described plumbous cover.
After adopting above structure, the terminal of the utility model storage battery compared with prior art has the following advantages:
Because the copper core of the terminal of the storage battery of the utility model is cylindric, described copper core is fixed in the described plumbous cover, therefore; Can not waste copper product; Can save material, also can increase copper core and plumbous contact area of overlapping, thereby reduce contact resistance in use; Avoid brokenly changing the fluid sealant between terminal and the battery cover, thereby also just can avoid the terminal place to spill the phenomenon of electrolyte.
As a kind of improvement of the utility model, the sidewall of described copper core is provided with at least one radial groove.After adopting this kind structure, can increase the fixing that combines between copper core and the plumbous cover, avoid copper core and lead to occur the phenomenon of loose contact between overlapping.
Another kind as the utility model improves, and described radial groove has four.This kind structure is an optimum implementation.

Fig. 1 is the blast structural representation of terminal of the storage battery of prior art.
Fig. 2 is the blast structural representation of terminal of the storage battery of the utility model.
Fig. 3 is the sectional structure sketch map of terminal of the storage battery of the utility model.
Shown in the figure:
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
See also Fig. 2 and shown in Figure 3, the terminal of the storage battery of the utility model comprises plumbous cover 1 and copper core 2.Described copper core 2 is provided with slot 2.1.Described copper core 2 is cylindric, and this copper core 2 is fixed in the described plumbous cover 1, compared with prior art, overlaps under the situation that 1 contact area equates with plumbous at copper core 2, can reduce the use amount of copper material; Under the equal situation of the use amount of copper, can increase the contact area of copper core 2 and plumbous cover 1.The sidewall of described copper core 2 is provided with at least one radial groove 2.2, and in this specific embodiment, described radial groove 2.2 is four.
Claims (3)
1. the terminal of a storage battery comprises plumbous cover (1) and copper core (2), and described copper core (2) is provided with slot (2.1), it is characterized in that: described copper core (2) is for cylindric, and described copper core (2) is fixed in the described plumbous cover (1).
2. the terminal of storage battery according to claim 1, it is characterized in that: the sidewall of described copper core (2) is provided with at least one radial groove (2.2).
