Description
TITLE OF THE INVENTION
[0001] Cast-on-strap mold and method for producing a terminal post
comprising an embedded member at one time
BACKGROUND OF THE INVENTION
[0002] The present invention relates to a cast-on-strap mold and a
method for producing a terminal post comprising an embedded member
at one time, which are mainly used in the production of storage
batteries of high capacity.
[0003] In the prior art, the common method of producing a terminal
post for a storage battery is to cast it with an embedded member as
its head, and then weld the head of the terminal post to a plate
pack. When the capacity of the storage battery is relatively high
and the working current exceeds a certain level, and as the
relatively poor connection of the plate pack and the terminal post
during welding leads to insecure connection and high contact
resistance, when the power output is relatively high, the storage
battery burns out easily. Further, the welding process is
complicated, the cost of production is high and the level of
automation is low. All these adversely affect the quality and the
power output of the storage battery.
BRIEF SUMMARY OF THE INVENTION
[0004] In view of the aforesaid disadvantages now present in the
prior art, the object of the present invention is to provide a
cast-on-strap mold and a method for producing a terminal post
comprising an embedded member at one time.
[0005] To attain this, the present invention generally comprises a
cast-on-strap mold for producing a terminal post comprising an
embedded member at one time, which is characterized in that a
cavity and a fixing bolt that correspond in size and position to
the embedded member are disposed therein, a positioning aperture is
disposed thereon, and the embedded member, the positioning aperture
and the fixing bolt correspond to one another.
[0006] The present invention further comprises a method for
producing a terminal post comprising an embedded member at one
time, which is characterized in that a cast-on-strap mold for
producing a terminal post comprising an embedded member at one time
is used and the method comprises the following steps: install the
embedded member into the cast-on-strap mold and secure it in
position by the fixing bolt, cast and weld the terminal post and
the plate pack, and then loosen the fixing bolt to take out the
cast and welded terminal post and plate pack.
[0007] 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.
[0008] 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.

DETAILED DESCRIPTION OF THE INVENTION
[0013] 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.
[0014] 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.
[0015] 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.
[0016] 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.degree. 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.
[0017] 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.
