SAFETY LATCH FOR ACCUMULATORS

The invention relates to a splash-proof closure device for electrolyte inlet openings in a storage battery ο In French patent No. _Q 70 37 497, a closure _{device was proposed?} to which on the one hand at least one plug from a hollow body belonged ^ whose lower part in the middle has a channel and whose upper open part has a sealing edge ₉ and on the other hand a 'stopper strip with fasteners for the plug on the inside and with at least one socket _s concentric to the Channel is in the stopper "

The invention is intended to provide such a closure device in a simple and inexpensive manner in the event that the Battery contains multiple plugs.

The subject of the invention is a splash-proof closure for electrolyte filler openings of a storage battery with on the one hand at least two plugs, each formed from a hollow body, the lower side of which in the middle has a channel and its open part has a sealing fire, and on the other hand, a stopper strip, which on its inside has at least two sockets that should be concentric to the channels in the plug, the Closure is characterized in that the sealing edges of the stopper are formed from a single flat piece to which the stopper strip is attached.

A preferred embodiment of the erfindungsgeraassen Device consists in the fact that this flat! Part, which at the same time the sealing edge, which forms the stopper, is connected to the stopper strip via at least one soft tongue, so that the whole forms a single part cast from plastic. Other features and advantages of the invention will become apparent over the course the description given on the basis of the "accompanying drawings.

Figures 1 and 2 show schematically an embodiment the locking device according to the invention in the open position from above and from the side »

Figure 3 shows an enlarged partial view of a Section through the same device in the closed state.

In Figures 1 and 2 are three similar stoppers 1, 2, 3, the three filling openings of an accumulator battery should close. The stopper 1, which is shown in detail in Figure 3, consists of a hollow body, the lateral fastening ribs 4 and the lower side of which has a central channel 5, the height of which is slightly less as the height of the plug 1j the channel has two openings 6 and 7, 3 / with the upper opening 6 having a smaller diameter as the lower opening 7. The lower area of the stopper 1 is furthermore provided with openings 8 through which the electrolyte, which is blown up by the gases generated in electrochemical processes, can run off «,

The sealing edges of the upper open plugs 1, 2, 3 form a single part 9 »which is flat and also has an outlet opening for gases receives,

In addition, the closure device according to the invention belongs to the invention a stopper strip 14, which has a soft Tongue 15 is firmly connected to the sealing edge 9 and 'has three cylindrical sockets 11, 12, 13 on its inside, which the should cover the upper part of the channels in the plugs 1, 2, 3. These sockets are preferably concentric with the channels located.

The stopper strip 14 has a lateral Y / ulst 17f which interacts elastically with a lateral groove 16, which is located in the sealing edge plate 9. Of course, any other fastening means can also be used with which the Stopper strip 14 and the sealing plate 9 are connected to one another. The tongue 15 can be replaced by several tongues, which are arranged on any side of the sealing edge plate 9.

The operation of a device according to the invention it becomes clear from FIG the difference in the cross sections of the openings 6 and 7 is braked and flow back into the battery. The minimal fraction of spatter that leaves the channel hits afterwards the obstacle created by the socket 11 of the stopper strip 14 is formed, and returns through the openings 8 back into the battery. The resulting from the electrochemical reaction For their part, gases can freely pass through the channel 5 and the opening 6 into the areas between the channel and the socket 11 Reach cavity and are discharged to the outside.

The device according to the invention can be used in all cases where the electrolyte filling openings are sealed of accumulator batteries must be carried out in such a way that that no acid splashes get outside, at the same time, however, the resulting Sase can be derived »

A closure device according to the invention can have "any number of plugs". She is from one Part made and preferably made of molded plastic, so can be made very easily and at low cost become β
