法が広く用いられている。2. Description of the Related Art In general, a sealed lead-acid battery has a safety valve provided with an electrolyte injection hole in order to prevent the deterioration of the negative electrode plate due to the incorporation of oxygen in the air into the battery and the rupture of the battery due to an increase in internal pressure in the battery. A rubber valve (hereinafter, rubber valve) is mounted as the hole. In order to activate the positive and negative active materials of such a storage battery, an unformed electrode plate is assembled into the battery, and then the electrolyte is injected through the injection hole, and the injection hole is inserted into the safety valve hole. A method called so-called battery case formation, in which an active material is activated by applying a current after a rubber valve is mounted, is widely used.

Is usually performed at a voltage at which oxygen / hydrogen gas is generated. In such a case, the rubber valve acts to open by the oxygen / hydrogen gas generated in the battery. Therefore, it is necessary to keep the rubber valve from coming off the liquid inlet during the chemical conversion. If the rubber valve is not sufficiently held, the rubber valve will come off from the liquid inlet, and the electrolyte or its mist will be scattered directly from inside the battery, corroding the battery terminals and the connecting parts of the chemical conversion device, Will adhere to.

I have. In such a case, in the finishing process after the battery case formation, the top cover is mounted on the battery so that they cannot be seen from the outside. It is a part and requires special equipment for mounting it, which causes the cost to rise due to the cost of parts, capital investment and equipment maintenance.

た。[0005] Further, after mounting a temporary safety valve, it is also practiced to hold the safety valve with a heavy object such as a lead weight through an acid-resistant resin plate so as not to come off from the safety valve hole. In such a case, the diffusion of the mist of the electrolytic solution discharged from the safety valve hole during the energization is sometimes prevented, and dew is formed around the safety valve hole, or the dew is formed on the surface of the weight by contacting the weight. In all of these cases, it is necessary to remove the dewed electrolytic solution, which is a factor that hinders productivity.

The battery case lid 2 of the storage battery 1 into which the electrolyte is injected is provided with a safety valve hole 3 corresponding to each cell chamber (not shown). The safety valve hole 3 is provided to protrude in a cylindrical shape from a concave portion 6 provided in the lid 2. The safety valve hole 3 also serves as an injection hole when the electrolyte is injected. A rubber valve 4 having a bottomed cylindrical shape is mounted in the safety valve hole 3.

The frame 5 is attached to the lid 2 during the energization of the storage battery 1. A protrusion 7 is provided on a portion of the frame body 5 which is in contact with the rubber valve 4 in accordance with the rubber valve 4. The rubber valve 4 is fitted into the projection 7 to hold at least the top surface of the rubber valve 4. The convex portion 7 is fitted into the concave portion 6 provided on the lid 2 to position the frame 5 and the lid 2. With such a configuration, the mist containing diluted sulfuric acid discharged from the safety valve hole 3 during the energization is dissipated into the atmosphere through the periphery of the frame 5 without being hindered by the frame 5. The mist containing dilute sulfuric acid is generally higher in temperature than the ambient temperature due to the heat generated during energization.

れ以下の値を基準とすれば良い。Although a part of the mist contacts the frame 5, the mist is hardly cooled when the thermal conductivity of the frame 5 is low, so that the mist is diffused into the atmosphere without dew condensation on the frame 5. . The selection of the thermal conductivity may be based on a value equal to or less than the material of the container lid.

なる。Further, since the frame 5 is required to have acid resistance since it comes into contact with the electrolyte mist, a synthetic resin such as a polypropylene resin or an ABS resin which is generally used as a battery case cover material is used. This is because when a material having excellent thermal conductivity such as a conventional lead weight is disposed around the safety valve hole, the mist is rapidly cooled and dew condensation occurs. According to the method of the present invention, the occurrence of such dew condensation and the adhesion of the dew condensation to the storage battery can be prevented. As a result, the work of removing the electrolyte adhering to the storage battery, which has been conventionally required, becomes unnecessary.

載置することもできる。Further, since the adhesion of the electrolytic solution to the frame can be suppressed, the cleaning of the frame can be omitted when the frame is used again. In addition, the frame 5 is engaged with the edge of the battery case lid 2 and provided with a locking portion 8 as a positioning means for positioning the frame 5 and the battery case lid 2, thereby displacing the frame 5 during energization. This prevents the rubber valve 4 from being detached from the safety valve hole 3. Therefore, it is possible to prevent the leakage of the electrolytic solution during energization and the adhesion of the electrolytic solution to the storage battery, and to activate the active material while releasing only the oxygen / hydrogen gas and the electrolyte mist to the outside of the storage battery. . When the weight of the frame alone is not sufficient, a weight can be placed on the upper portion of the frame 5.

Further, since the adhesion of the electrolytic solution to the storage battery and the like can be prevented, the operation of removing the adhered electrolytic solution becomes unnecessary, and the productivity can be significantly improved.
