Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a type of storage battery, such as a ready-to-use storage battery, whose liquid injection port is always sealed.

(Prior Art) Conventional storage batteries of this type, typically sealed ready-to-use storage batteries, have a problem in which the active materials in the cathode plates in each cell chamber come into contact with the atmosphere and react with oxygen before use. To prevent capacity reduction, a battery container with the liquid opening of each cell sealed with a sealant is prepared separately from the battery container. It consists of a connected liquid port plug with each liquid port plug attached to a common longitudinal board in order to seal the liquid at the same time.
When shipped and sold as a storage battery, the battery container and the liquid outlet plug are handled separately from each other.

(Problem to be solved by the invention) In the conventional storage battery mentioned above, the liquid spout plug is handled separately from the battery container, so shipping and transportation as a storage battery is troublesome, and the liquid spout plug may be lost. .

(Means for Solving the Problems) The present invention relates to a storage battery that aims to eliminate the drawbacks of the conventional storage batteries described above, and includes a battery container whose liquid opening is sealed with a sealing material, and a sealing material when pouring liquid. In order to seal the liquid port after removal, in a storage battery consisting of a connecting type liquid port plug, which is prepared separately from the battery and each liquid port plug is connected to a connecting plate, the outside of the lid of the battery container is A concave space is formed in the side surface, and a hole for temporarily attaching a liquid spout is provided in the concave space, each liquid spout is removably fitted into the hole for temporarily attaching the liquid spout, and the connecting plate is inserted through the concave space. To construct a storage battery that is housed within the concave space without protruding.

(Example) Next, embodiments of the present invention will be described.

FIGS. 1 and 2 show an example of a storage battery according to the present invention, and reference numeral 1 indicates a storage battery container made of thermoplastic synthetic resin. The battery container 1 includes a monoblock battery container 1a with six cells connected in series, the interior of which is divided into six cell chambers, and a casing 1b that is thermally welded and sealed on the top surface of the monoblock battery container 1a.
It consists of The top surface of the lid 1b has six liquid ports 2 opened for each cell chamber, and each liquid port 2 is adhered and sealed with a common longitudinal sealing material 3. . Thus, before use, the battery container 1 is configured with all liquid ports 2 sealed, so that the atmosphere will not oxidize the cathode plates of the cells inside. When injecting liquid into the battery container 1, it is necessary to peel off and remove the sealing material 3, and after injecting liquid into each cell chamber, it is necessary to seal the battery container 1 again.
A liquid port plug 4 is separately prepared for each liquid port 2. Normally, these liquid port plugs 4 are connected to a longitudinal connecting plate 5.
The liquid ports 2, 2, .
It is prepared and prepared in a connecting type liquid spout plug 6 connected to the body.
Then, apply this to the liquid ports 2, 2, . Preferably, this connecting type liquid spout 6 is produced by one-piece molding. When this connecting type liquid spout stopper 6 is applied, in order to prevent the connecting plate 5 from protruding from the top surface of the lid body 1b, the longitudinal fitting concave surface into which this connecting type 5 fits is placed on the top surface of the lid body 1b in advance. Generally, it is provided.

The above configuration is no different from a conventional sealed ready-to-use battery.

In the illustrated embodiment, the outer surface of the battery container 1,
That is, the outer surface of the lid 1b, for example, the side surface parallel to the arrangement direction of the liquid ports 2, 2..., is set back from the side edge surface of the battery case 1a to form a concave space 8, as shown clearly in FIG. and the concave space 8
A hole 7 for temporarily attaching a liquid spout into which the liquid spout 4 fits is formed inside. The liquid spout plug temporary mounting holes 7 have the same pitch spacing as the liquid spout plugs 4, 4, . . . arranged in the connecting type liquid spout 6, and extend horizontally. As shown in the second figure, when the liquid outlet plug 6 is attached to the battery container 1, the connecting plate 5 fits within the concave space 8, and its outer surface is in the same plane as the outer surface of the lower battery case 1a. ,
The connecting plate 5 is designed to prevent hands or equipment from hitting it and accidentally detaching it during handling.

The means for removably fixing the connecting liquid port plug 6 to the surface of the battery container is arbitrary. It is sufficient that at least one of the liquid port plugs 4, 4... fitted into these holes 7 has approximately the same diameter as the diameter of the corresponding hole 7, and is tightly fitted thereto. . In the above embodiment, the liquid port plugs 4, 4 at both ends are tightly fitted into the respective holes 7, 7. Thus, the other intermediate holes 7, 7... are connected to the liquid port plug 4,
4...It has a larger diameter, and the connecting liquid port plug 6 as a whole can be pulled out relatively easily. In addition, if all the liquid port plugs 4, 4... are configured to fit loosely into the holes 7, 7..., engagement protrusions are provided at both ends of the connecting plate 5 (not shown), and the corresponding battery Engagement recesses that engage with these protrusions may be provided on the outer surface of the container 1.

In the above embodiment, after peeling off the sealing material 3 and injecting a predetermined amount of electrolyte from each of the liquid ports 2, the connecting type liquid port stopper 6, which has been attached to the battery container 1 in advance, is attached. It is pulled out from the holes 7, 7, . . . and inserted into each of the liquid ports 2, 2, .

(Effect of the invention) As described above, according to the present invention, a concave space is formed on the outer surface of the battery container, and a hole for temporarily attaching a liquid spout is provided in the concave space, and a connecting type liquid spout can be attached and detached in advance to this hole. , and the connecting plate of the connecting type liquid port stopper is housed within the recessed space without protruding beyond the recessed space to form a storage battery.
In handling the shipping etc., as in the past,
Compared to storage batteries, which are handled by simply attaching a connecting liquid spout prepared separately from the battery container to the battery container for shipping, handling can be done easily and quickly. It brings about effects such as being able to prevent the liquid from being lost, and it also brings about effects such as preventing the connected liquid spout from accidentally coming off due to hitting hands or equipment during handling.
