  • The casting and welding of the terminal post and the plate pack of the present invention comprises the following steps: immerse the cast-on-strap mold into a molten lead alloy, take out the cast-on-strap mold and cool it down to the temperature for casting and welding, immerse the part of the plate pack to be connected to the terminal post into the molten lead alloy in the cast-on-strap mold, and the molten lead alloy in the cast-on-strap mold cools down to form a welding layer to unite the terminal post and the plate pack together in one piece.
  • In comparison with the prior art, the present invention has the following advantages and effects: As the terminal post is formed at one time and is cast and welded to the plate pack at the same time, it increases the effects of the strength and the connection of the plate pack, the terminal post and the embedded member which are formed in one piece at one time, and it also significantly increases the capacity of the storage battery for conducting high electric current. The highest power output is about 30 percent higher than the original power output. The production steps are saved. The cost of production is lowered. The level of automation and the quality of the production can be enhanced.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 shows the construction of the terminal post of the embodiment of the present invention.
  • FIG. 2 shows the construction of the embodiment of the present invention during casting and welding.
  • FIG. 3 shows the method for producing the embodiment of the present invention.
  • FIG. 4 shows the construction of the storage battery with the embodiment produced by the present invention.
    •  DETAILED DESCRIPTION OF THE INVENTION
  • As illustrated in FIGS. 1 and 2, the terminal post 6 produced by the embodiment of the present invention is disposed with an embedded member 6-1 and a welding layer 6-2 that are cast and formed at one time. The embedded member 6-1 is disposed with a connecting thread 6-3. The connecting thread 6-3 corresponds to that on a connector of an electrical appliance. The embedded member 6-1 is made of copper, and the welding layer on its outer surface is made of lead alloy. At this moment, as the connecting thread 6-3 faces up, the connector of the electrical appliance can easily be screwed in. As the terminal post 6 is formed at one time and is cast and welded to the plate pack 5, it increases the effects of the strength and the connection of the plate pack 5, the terminal post 6 and the embedded member 6-1 which are formed in one piece at one time. If the output direction of the terminal post 6 is required to be changed to another direction for output, a connector with the desired direction for output can be added.
  • As illustrated in FIG. 2, the present invention further comprises a cast-on-strap mold 12 for casting and welding of the terminal post 6 as mentioned above. The cast-on-strap mold 12 is disposed with a cavity 13 that corresponds in size and position to the embedded member 6-1. The cast-on-strap mold 12 is disposed with a positioning aperture 16, and the embedded member 6-1, the positioning aperture 16 and the fixing bolt 15 correspond to one another. When the embedded member 6-1 is fixed on the positioning aperture 16 by the fixing bolt 15, the embedded member 6-1 has to cover the positioning aperture 16 completely.
  • As illustrated in FIG. 3, the present invention further comprises the method for producing the terminal post 6 as mentioned above which comprises the following steps: install the embedded member 6-1 into the cast-on-strap mold 12 and secure it in position by the fixing bolt 15, cast and weld the terminal post 6 and the plate pack 5, and then loosen the fixing bolt 15 to take out the cast and welded terminal post 6 and plate pack 5. The installation of the embedded member 6-1 into the cast-on-strap mold 12 and the securing of which in position by the fixing bolt 15 further comprises: the connecting thread 6-3 of the embedded member 6-1 faces down aiming at the positioning aperture 16, the fixing bolt 15 passes through the positioning aperture 16 and screws on the connecting thread 6-3 tightly, so that the end surface of the connecting thread 6-3 of the embedded member 6-1 securely engages with the bottom of the cast-on-strap mold 12, and the embedded member 6-1 is positioned accurately and covers the positioning aperture 16 completely.
  • The casting and welding of the terminal post 6 and the plate pack 5 of the present invention can comprise the following steps: immerse the cast-on-strap mold 12 into a molten lead alloy (at this moment, the molten lead alloy at a temperature higher than the temperature for casting and welding fills up the cavity 13 completely), take out the cast-on-strap mold 12 and cool it down to the temperature for casting and welding (usually at about 375° C.), immerse the part of the plate pack 5 to be connected to the terminal post 6 into the molten lead alloy in the cast-on-strap mold 12, and the molten lead alloy in the cast-on-strap mold 12 cools down to form a welding layer 6-2 to unite the terminal post 6 and the plate pack 5 together in one piece.
  • As illustrated in FIG. 4, the storage battery with the embodiment produced by the present invention comprises a battery cover 1, a battery case 2, a plate pack 5 and a terminal post 6. As the terminal post 6 is formed at one time and is cast and welded to the plate pack 5 at the same time, it increases the effects of the strength and the connection of the plate pack 5, the terminal post 6 and the embedded member 6-1 which are formed in one piece at one time, and it also significantly increases the capacity of the storage battery for conducting high electric current. The highest power output is about 30 percent higher than the original power output. The production steps are saved. The cost of production is lowered. The level of automation and the quality of the production can be enhanced.
