Description

[Detailed description of the invention] The present invention accommodates a plurality of batteries in a case inside a case, electrically connects these batteries in parallel, and places a predetermined line on one side of the case that connects the terminals of these batteries. This invention relates to an improvement in an assembled battery in which screw terminals for external connection of both positive and negative poles are provided at a distance.

This type of assembled battery is used as a simple backup power source in various battery-applied devices.

Also, the relationship between the screw terminal for external connection and the connection lead between the batteries in the case is limited by the structure of the power connection part of the device that uses this battery, and the lead wire on the device side can be connected by tightening. At the same time, in order to enable tightening of the connection leads in the case, positive and negative terminals are provided at a predetermined distance on a line connecting the terminal portions of a plurality of batteries.

Therefore, the screw terminal on either one of the negative terminals will be in direct contact with the terminal of one pole of the battery and one end of the lead connecting the terminals of the same polarity of this battery, but the screw terminal on the other side will be in direct contact with the terminal of one pole of the battery, and the other screw terminal will be in direct contact with the terminal of one pole of the battery and one end of the lead connecting the terminals of the same polarity of this battery. Pole Connection In order to fix the other end of the IJ-de, it is necessary to maintain electrical insulation between the lead or the lead and one terminal of the battery.

For this reason, when fixing the other end of the lead to the case with a screw terminal, the screw terminal is fastened to the case with an insulating paper or an insulating plate interposed.

However, when assembling an assembled battery, intervening insulating paper or insulating plates when fixing connection leads with screw terminals becomes complicated in terms of process, and it is also possible to forget to insert these insulating materials, or even if they are inserted, they will not work properly. There was a problem that insufficient insulation was likely to occur, causing internal short circuits in the battery.

The present invention solves these problems by configuring the screw terminal for external connection, which should be conductive, with an insulating material, without using insulating paper, insulating plates, etc., and tightening the lock nut and lead wire. This problem was solved by making the nut conductive.

Hereinafter, an example thereof will be explained with reference to the drawings.

In the figure, reference numeral 1 denotes an insulating case for both exterior and battery storage, and inside thereof a plurality of batteries 2 are housed in an array with terminals of the same polarity oriented in the same direction.

3 and 4 are external connection screw terminals provided on one side of the case.

Among these screw terminals, 3 have conductivity, and the battery 2
The liquid is applied directly to the anode terminal of the anode terminal, and the connection lead 5 on the anode side
one end is fixed.

On the other hand, the terminal 4 is a cathode side terminal fixed to the case 1 by a lock nut 8 connected to the cathode side connection lead 6 of the battery by a lead wire 7, and is used to fix the other end of the anode side glue part 5. Therefore, we used insulating synthetic resin bolts.

Therefore, with this screw terminal 4, the anode side connection lead 5 can be directly fixed to the case without using any insulating material, as shown enlarged in FIG. 2, and the other end of the lead 5 can be folded downward. By doing so, this part can be brought into contact with the anode terminal of the battery 2 at the right end.

The screw terminal 3 on the anode side is conductive, and is connected to a lock nut 8 and a lead wire tightening nut 9 on the device side.
The screw terminal 4 on the cathode side can be electrically connected by tightening the lead wire on the device side with the lock nut 8 and the tightening nut 9.

In this way, in the assembled battery of the present invention, the screw terminal of either the positive or negative pole is made of a conductive material, and the screw terminal of the other pole is made of an insulating material, and the insulating screw terminal is made of a conductive material. Since the nut is screwed together to connect the lead of the other terminal, it is possible to place two terminals, positive and negative, on one side of the case at a predetermined interval on a line connecting the terminals of the battery. I can,
By forming the screw terminal on the other pole with an insulating material, there is no need for insulating paper, etc. to insulate the terminal part from the lead on one pole, which was required in the past, making assembly of the battery assembly more efficient. There is an advantage that it can be done.
