Abstract
Disclosed is a storage battery terminal improvement structure which includes a column core and a holding seat covering the column core. The column core includes a copper core whose top is provided with a columniform enlarged part; the hollow part and the outer part of the copper core below the columniform enlarged part are covered by aluminum; the outer part of the column core is the holding seat made of lead; the columniform enlarged part of the copper core is exposed outside the holding seat; and part of the outer part of the holding seat is covered by plastic covering layer. The utility model changes the traditional full copper column core to the material made by copper and aluminum; besides the conductive performance and the strength of the storage battery terminal are maintained, the copper material is greatly saved, thereby making the material cost greatly reduced. Meanwhile, the plastic covering the part of the outer part of the lead made holding seat also increases the sealing performance of the terminal.
Description
Technical field
The utility model relates to the battery technology field, especially relates to a kind of accumulator terminal structure.
Background technology
Seat is held in plumbous matter or terne metal quality guarantee that traditional accumulator terminal structure mainly comprises a tubulose stake core and coating this core, and a stake core all is to adopt solid copper bar to process at present.And lasting unprecedentedly soaring along with the copper price, so the manufacturing cost of accumulator terminal also increases in succession.So to present resource scarcity, advocate under the energy-conservation situation of falling material energetically, propose a kind ofly can economize material and reduce cost, can keep the accumulator terminal of its original performance to become a kind of extremely urgent work again.But on the accumulator terminal structure and material, can save new technology or new utility model creation or relatively more rare that cost drops into.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of accumulator terminal manufacturing cost that can reduce at above-mentioned prior art present situation, can keep the accumulator terminal of its original performance again.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this accumulator terminal, mainly comprise a core and coating the maintenance seat of this core, it is characterized in that described stake core includes a bronze medal core, one hollow cylindrical expansion section is arranged at the top of copper core, hollow position and the copper core outside that is positioned at below this cylindrical expansion section coat with aluminium, the outside of stake core is that seat is held in described plumbous quality guarantee, and the cylindrical expansion section of copper core is exposed to and keeps outside the seat, in the also local coating plastic coating layer in outside that keeps seat.
Described copper core is a die casting.
The cylindrical expansion section at described copper core top is a hollow-core construction.
Compared with prior art, advantage of the present utility model is: the utility model changes traditional complete copper stake core into copper and two kinds of materials of aluminium constitute, except the electric conductivity that can keep accumulator terminal and intensity etc., be to save copper material the most significantly, cost of material is reduced greatly; The external partial that while is held seat in plumbous quality guarantee is coated with plastics, makes the sealing property of terminal improve.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the profile schematic diagram of copper core.
Fig. 3 is the profile schematic diagram of the utility model embodiment.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Mainly comprise a core 1 and coating the maintenance seat 2 of this core that as Fig. 1, accumulator terminal shown in Figure 3 its king-pile core is made up of two sections of material, copper and aluminium.Specifically as shown in Figure 2, it comprises the copper core 11 that a die-casting process is shaped, the top of copper core 11 has a hollow cylindrical expansion section, outside at hollow position and the copper core below the cylindrical expansion section with aluminium 12 coatings, the stake core of making like this 1, with consistent, be a cylinder from the appearance with the copper stake of tradition core.Keep seat 2 to adopt die-cast to form, extrusion process adopts traditional technology.It mainly comprises following three operations:
First: stake core 1 is inserted in the compression mod as core;
Second: the lead or the terne metal die casting liquation of fusion are pressed in the die cavity of compression mod, and die-cast coats the maintenance seat 2 of stake core;
The 3rd: after treating natural cooling, die sinking can obtain the accumulator terminal of high dimensional accuracy, high-compactness and high surface finish.
And, also be injected with ABS plastic or rubber adhesive 3 in the cylindrical stage casing that keeps seat 2 in order to improve the sealing effectiveness of accumulator terminal.
By accumulator terminal provided by the utility model, adopt the accumulator terminal structure of copper stake core relatively, cost reduces greatly, and end product quality improves.
Claims (2)
1, a kind of accumulator terminal structure-improved, mainly comprise a core (1) and coating the maintenance seat (2) of this core, it is characterized in that: described stake core (1) includes a bronze medal core (11), one hollow cylindrical expansion section is arranged at the top of copper core (11), hollow position and the copper core that is positioned at below this cylindrical expansion section are outside with aluminium (12) coating, the outside of stake core (1) is a described maintenance seat (2), and the cylindrical expansion section of copper core is exposed to and keeps also being coated with plastic packets coating (3) in the part in the outside that keeps seat outside the seat.
2, accumulator terminal structure-improved as claimed in claim 1 is characterized in that: described copper core (11) is a die casting.
