Description

[Detailed Description of the Invention] The present invention relates to a battery device, particularly a battery body including one or more unit cells each having a bottomed cylindrical outer can that also serves as a single-pole terminal, and an insulator covered on the outer peripheral surface of the battery body. Regarding a battery device comprising a tube and a terminal fitting welded and fixed to the one-pole terminal located at one end of the battery body, the free end terminal portion of the terminal fitting is separated from the insulating tube to prevent connection with a connecting terminal etc. It is something that can be done easily.

To explain this type of conventional device, as is clear from FIG. 1, which is a partially cutaway front view of the battery device, it has one or more unit cells B each having a bottomed cylindrical outer can A that also serves as a negative electrode terminal. The outer peripheral surface of the battery body C is covered with an insulating tube D, and a terminal fitting F is connected and fixed to the negative electrode terminal E located at one end of the battery body C, and the bent piece G of the terminal fitting is insulated. Close to Tube D. When transported in this state and used, the bent piece G is bent into a broken line or a dashed-dotted line so that the free end terminal H of the bent piece G is separated from the insulating tube D, and a connecting terminal etc. is attached to the terminal part H. They fit together and connect. For this reason, in the conventional device, it is necessary to bend the bending piece G, which has the disadvantage of being inconvenient to use.

The present invention has been devised in view of these points, and includes a terminal fitting that has the same polarity as the outer can of the unit cell included in the battery body and is welded and fixed to a single pole terminal located at one end of the battery body. , a base end piece welded and fixed to the single pole terminal and a bent piece opposing an insulating tube covered with the battery body are arranged in an L shape,
Further, the terminal fitting is provided with a latch piece that is parallel to the bent piece and comes into contact with the insulating tube to separate the free end terminal portion of the bent piece from the insulating tube, and the connecting terminal The purpose is to facilitate the connection of devices such as

An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a partially cutaway front view of the battery device, and FIG. 3 is a perspective view of the terminal fitting. In these drawings, 1 is a battery body, which includes one or more unit cells 2 in series. Each unit cell 2 includes a bottomed cylindrical outer can 3 that also serves as a negative terminal, and a positive terminal 4 provided on a sealing plate that covers the top opening of the case. A short-circuit connection is made by the tab fitting 5. The outer peripheral surface of the battery body 1 is covered with an insulating tube 6 made of vinyl chloride resin or paper. Reference numeral 7 denotes a terminal fitting, and a base end piece 9 is welded to the negative electrode terminal 8 located at the lower end of the battery body 1, and a bent piece 10 opposes the insulating tube 6.
It has an L-shape and a hooking piece 11.
This latching piece 11 is parallel to the bent piece 10, and comes into contact with the insulating tube 6 so that the free end terminal portion 1 of the bent piece 10
2 from the insulating tube 6. That is, by spot welding the proximal end piece 9 to the negative electrode terminal 8 with the hooking piece 11 in contact with the insulating tube 6, the free end terminal portion 12 becomes in a state separated from the insulating tube 6, and the free end terminal portion 12 Connection terminal 13
can be connected by mating. In addition, instead of using the connecting terminal 13, connect the lead wire to the free end terminal part 1.
2, since the free end terminal portion 12 is spaced apart from the insulating tube 6, the solder melting heat during the soldering work is transmitted to the insulating tube 6.
The tube will not be damaged. Also, the latch piece 11
Even if burrs 14 shown by broken lines in FIG. 3 are formed at both ends of the tube during formation, and the burrs may penetrate through the insulating tube 6 and come into contact with the outer can 3, the outer can 3 and the negative electrode terminal 8 are Since they have the same polarity, there is no problem.

As described above, the present invention includes a base end piece in which a terminal fitting is welded and fixed to a single pole terminal located at one end of a battery body;
It has an L-shaped bent piece opposing the insulating tube covered on the outer peripheral surface of the battery body, and is formed parallel to the bent piece and comes into contact with the insulating tube to prevent the bending piece from playing. Since it is provided with a latch piece that separates the end terminal part from the insulating tube,
A connecting terminal or the like can be connected to the free end terminal portion without bending the bent piece as in the conventional device, and usability can be improved.
