Electric battery

The invention relates to an electric battery.

Alkaline batteries with air depolarization are known Zinc / air batteries, case size for 4.5 volts, with positive and negative electrodes inside, which are connected in parallel to the negative poles of the half-elements then to establish a series connection between the negative and positive poles thus formed. Such a structure, as it is described in the Spanish utility model no. 175.892 registered in the name of the applicant, is out There are mainly two reasons that are very difficult or costly, namely:

1. Because of the difficult handling when interconnecting and during operation;

2. Because of the risk of a short circuit between the electrodes, which is why they should be handled with extreme care during assembly Need to become.

In later patent applications, particularly in Spanish patent specification No. 450,068 "Improvements in electrical Batteries ", one has moved from the assembly of the elements in a horizontal position to a type of assembly in a vertical position and has housed the elements in a box or housing, which contains three cells inside and in which the electrodes are through Openings passed through on the underside and thus the connections on the one hand on the upper part and on the other hand on the lower part Part are made, in which case two covers are necessary to cover the connections on both sides.

The object of the invention is to create an electric battery that can be produced easily and inexpensively and in which the above-mentioned difficulties do not arise.

This object is achieved by an electric battery which, according to the invention, is characterized in that the battery contains two negative electrodes and one positive electrode per element, all arranged in the same direction.

According to the invention, all electrodes are mounted in the same direction, with each new element two negative and has a positive electrode and assembly is facilitated by not having the half-members and electrodes in opposite position must be arranged. Furthermore, the three elements are assembled in the same direction, and it is it is not necessary to place the middle element opposite in order to enable its connection.

According to a particularly advantageous embodiment of the invention a printed circuit is provided, the parallel connection for two half-elements and the series connection contains positive / negative; this is how a battery is created with secure connections and easy assembly.

Further features and usefulnesses of the invention emerge from the description of exemplary embodiments of the figures. From the figures show:

6 shows a positive outer terminal lug of the battery in the embodiment shown in FIG.

In the drawing, the components are identified by the following reference symbols:

1 - battery element, positive electrode;

1 ¹ - battery half-element, negative electrode;

2 - outer casing made of plastic;

3 - Printed circuit board;

4 - outer cover of the battery;

5 - Battery negative terminal lug;

6 - Battery positive terminal lug; and

7 - solder joint.

The battery elements 1, which are mounted in the same direction and with positive electrodes 1 and negative electrodes 1 'on the top, are surrounded by two printed circuit ^{boards 3, which are shown in Figure 4 1} ' and printed conductor tracks parallel to the negative half-elements and the Have positive / negative connections required to form the battery.

In another embodiment of the invention, all electrodes, after they have been placed in a vertical position, are through the openings of a printed circuit board 3, as shown in Figure 4, passed, whereby they finally are inserted into the circuit.

After the printed circuit or circuits have been attached, the electrodes are bent over, each group in the direction the connections, and then soldered or electrically welded with the addition of tin.

The outer plates 5, 6 are soldered to the positive and negative poles of the battery at the appropriate points.

The soldering points are protected by a suitable material, such as paint, tar, paraffin, etc.

The one from the battery elements 1, which are combined to form a battery are, formed block is inserted into an outer housing 2 made of plastic, the inside three cell-like container each of which is provided for receiving a battery element. A cardboard container can also be used are, as in already known embodiments with the also known top lid.

The outer housing 2 is closed by a cover 4 or 4 ', which is attached to the housing over the entire circumferential length by means of glue or ultrasound and the two slots contains, through which the lugs 5, 6 are led to the outside to form the positive and negative pole of the battery.

The access of air, which is necessary for the depolarization process of the battery, is ensured by the im Cover existing openings for the implementation of the terminal lugs.

A seal is placed on the lid to ensure that the battery has not been used before it is sold.

Another embodiment is shown in FIG. the Battery elements 1 are inserted vertically into the housing 2, but the middle element is opposite the other two Elements arranged opposite, as well as the positive electrode 1 opposite to the negative electrodes of the two half-elements 1 'is arranged. This arrangement ensures that the negative electrodes are long enough to

when inserting the elements in the housing to reach the top, where the connections are made, the negative tab 5 of the battery protrudes with one end to the outside. Then the positive flag 6, which is also after protrudes outside, attached, and finally the outer cover 4 of the battery is placed so that it is fully assembled is, without the use of printed circuits and avoiding openings at the bottom of the housing 2, the would require a second cover to protect the connections.

The type of assembly proposed according to the invention creates a battery that differs from conventional batteries, in which alkali elements in platelet or tablet form are used, due to easier assembly, safety of the There is a significant difference between connections or soldering points and protecting the soldering points by suitable means.

The concept of the invention can also be applied to other types of elements and batteries in which a parallel or series connection is required.

Materials, shape, color and dimensions can be determined by a person skilled in the art or compared to the exemplary embodiment described be changed.
