Description

[Detailed Description of the Invention] The present invention relates to a lead-acid battery electrode plate group connection device.
In a conventional device of this type, each cathode plate and each anode plate of the electrode plate group are provided at one end of the upper edge of each plate, and the cathode and anode plates are arranged alternately to overlap each other. Well, the first
As shown in the figure, on the upper surface of the electrode plate group A, the lug B1 group of the cathode plate B group is arranged in a row on one side, and the lug C1 group of the anode plate C group is arranged in a row on the other side. Since the ear rows B1...C1... are connected by the ear group connecting straps D and D', each cathode plate B
In each anode plate C, the distance from each location on each electrode plate surface to each lug B1 or C1, which is a current collecting portion, becomes long, resulting in a disadvantage that the battery voltage becomes low. In addition, the straps D and D' exist on both sides of the battery cell chamber,
Because of the structure in which the straps of opposite polarity on both sides of the adjacent cell chambers are connected to the intermediate pole pillars d and d', the connection between the cells is extremely susceptible to vibration.

In addition, since the respective ear rows B1...C1... of the negative and anode plates are located apart from each other on both sides of the cell chamber, the straps D,
Forming D′ separately using a gas burner, a lead rod, a jig, etc. would make the welding work extremely troublesome.

The present invention eliminates such conventional drawbacks and provides a lead-acid battery electrode plate group connection device that is relatively easy to weld and improves the battery voltage and seismic resistance of the connection between cells. Straps 3 for connecting electrode plate ears are provided on both sides of the electrically insulating member 2 having a shape.
3' and a longitudinal connecting member 1 comprising intermediate pole posts 8, 8' at the ends of the plate lug group connecting straps 3, 3' is attached to the upper surface of the plate group 4 in its width direction. The rows of cathode plate lugs 5a and the rows of anode plate lugs 6a protruding from the intermediate portions of the upper edges of the cathode plate 5 group and the anode plate 6 group of the electrode plate group 4 are connected to their opposing connections, respectively. A lead-acid battery plate group connection device which is connected to the lead-acid battery plate group straps 3 and 3'.

An example of implementing the present invention will be described with reference to FIGS. 2 to 4.

Reference numeral 1 denotes a longitudinal connecting member in which an electrically insulating member 2 made of a synthetic resin material is joined together with straps 3, 3' for connecting electrode plate lug groups on both sides thereof. In the illustrated embodiment, the synthetic resin member 2 is made of a long rectangular plate, the length of which is equal to the thickness of the electrode plate group 4 in the overlapping direction. On the top surface of the plate, connect straps 3, 3' for connecting lead or lead alloy electrode plate ears of the same length and width as appropriate along the length of the plate on both sides with a gap in the center. A predetermined number of cathode plate groups 5 and anode plate group 6 constituting the electrode plate group 4 are formed by polymerizing and bonding them into one body using a chemical agent or other means, and are arranged at a predetermined interval along both sides of the plate group. A large number of comb-like fitting holes 7...7' for insertion and welding connections.
... to constitute a long rectangular plate-shaped connection member 1 as shown in the fourth figure, and this is placed at the middle of the upper surface of the electrode plate group 4 in the width direction as shown in FIGS. 2 and 3. Fitting holes 7...7'... are arranged so that the center line is aligned with the center line of the electrode plate group 4, and the fitting holes 7...7'...
The respective ears 5a and 6a projecting upward from the intermediate portions of the upper edges of the cathode plate 5 and the anode plate 6 are respectively fitted and welded to their respective straps 3 and 3' using a gas burner or the like. constitute a cathode strap and an anode strap, respectively. the strap 3,
3' are provided with ear-shaped intermediate pole pillars 8, 8' that protrude upward, but when they are arranged on the center line as shown in the second figure, The so-called cell-to-cell connection of the cathode and anode straps of each plate group is made at the center of each plate group in the width direction, in other words, the cell-to-cell connection is made on the center line of the monoblock storage battery, so it is not susceptible to vibration. On the other hand, it becomes a stable and strong inter-cell connection, which is particularly preferable. In addition, on the lower surface of the synthetic resin plate 2, a longitudinal partition wall 2a is provided on the center line thereof and projects downward, so that on both sides thereof there are parallel on-yang plate lug groups 5a...anode plate lug groups 6a.
It was designed to serve as an electrical barrier between the two.
The connection device for the electrode plate group 4 of the present invention configured as described above has ears 5a and 6a protruding from the middle portion of the upper edge of each cathode plate 5 and each anode plate 6, respectively, and these ears are connected to the electrode plate group. 4 is connected to the straps 3 and 3' provided in advance on both sides of the connecting member 1 having the above structure, so that each ear 5 is
Since the distance to a and 6a is relatively short, the current collection efficiency is improved, resulting in an improvement in battery voltage.Since the connection between cells is made in the middle, vibration resistance is improved, and the connection member 1 is The synthetic resin plate 2 extending to the lower surface prevents a short circuit phenomenon caused by elongation or upward bending of the lattice frame at the upper edge of the Yin-Yang straps 3, 3' on both sides and the polar plates 6, 5 of different polarity. Further, the negative and anode plate lug groups 5a...5b... are gathered in the middle,
Moreover, since the straps 3 and 3' are prepared in advance, the work of connecting them is easy, and the connection between cells is also facilitated. As shown in the figure, the plate-shaped synthetic resin member 2 may be provided with a rib 2b for filling the gap at the center of the upper surface of the plate and regulating the separation of the straps 3, 3' on both sides when attached. The present invention uses a bar-shaped electrically insulating member instead of the plate-shaped electrically insulating member 2 of the above embodiment, and has straps 3 on both sides of the bar-shaped electrically insulating member.
It goes without saying that 3' may be tied together.

In this way, according to the present invention, the longitudinal connecting member 1, which has straps 3, 3' tied to both sides of a bar-shaped or plate-shaped electrically insulating member, is arranged at the middle of the upper surface of the electrode plate group 4 in the width direction. Since the cathode plate lugs 5a row and anode plate lugs 6a row of the electrode plate group 4 are connected to the straps 3 and 3', a battery with good current collection efficiency and improved voltage characteristics can be obtained. intermediate pole pillar 8 of the anode strap 3, 3' located in the middle;
Since the inter-cell connections are made at 8', respectively. It has the effect of improving its earthquake resistance.
