Description

Description of the invention

The scope of the invention is a device for protection! battery electrodes. 2 Batteries with a dry galvanic element, commonly used for portable devices, such as, for example, pocket electric lights, toys, and the like, are cylindrical and are equipped with a central electrode and an output electrode. The central electrode is generally formed as a contact pin, similar to a protrusion, having a diameter that is much smaller than the outer diameter of the battery. From the central electrode, a positive contact is formed. At the other end of the battery 70, an output electrode is formed, which is given the shape of a flat contact plate with a much larger diameter than the central electrode. Often, the batteries are arranged physically, and also electrically, in sequence so that the central electrode of the first battery directly contacts the output electrode of the second battery. If more than two batteries are provided, the central electrode of the second battery will directly contact the output electrode of the third battery, etc.

For example, in a pocket electric flashlight, the electric circuit is randomly created from one electrode of the battery, for example, the central electrode of the front battery through a conductor to the switch, and then to one electrode of the lamp cylinder. After passing through the filament, the incandescent bulb of the lamp! The electric circuit goes through the second electrode of the lamp cylinder! in electrically conductive contact with the conductor, which, in turn, is electrically conductively connected to the body of the pocket electric flashlight. The body of the pocket electric flashlight itself, when it is made of metal, or the conductor extending along the inner side! the case, for example, if the case is made of plastic, usually contains an electrically conductive path to the electrical conductor, usually a spring element that is in contact with the second electrode of the battery, i.e. usually with the input electrode of the last battery. c 22 The actuation of the switch to complete the electric circuit allows the electric current (ge) to flow through the filament, thus creating light, which is objectively focused by the reflector to form a beam of light.

In the case of medium and larger batteries or rechargeable batteries, which are often used in pocket electric flashlights for public safety purposes by police and fire personnel, zelectrod! batteries can be deformed by a physical impact, to which a flashlight can be subjected. On the one hand, the input electrode can be deformed, since it has a relatively large diameter and, therefore, low rigidity. On the other hand, the central electrode may be deformed, since it is subjected to a relatively large compressive load due to its small diameter. M contact pin, similar to a protrusion, along the central axis of the battery. Although the above-mentioned problems can occur if only two batteries are connected in series, the electrodes! even more likely you should! avoid deformation if a column consisting of a large number of batteries is provided, for example, a column of four or five batteries, since the weight of the battery column is greater when more batteries are provided with Z 0. Consequently, the effect of the shock received by the electrodes increases with a larger number of batteries. The probability of deformation is even higher if heavier batteries with a larger outer diameter are used, since in this case the impact from the impact is further increased. If there is extensive deformation of the electrodes, the last electrode may lose contact with the last conductor, which is usually a spring, or the front electrode may lose contact with the conductor connected to one of the two electrodes of the lamp bulb. More than that, it's possible that it's faulty! pocket electric flashlight will lose contact with each other, so that they will be separated by intervals relative to each other in the longitudinal direction. In this case, the electrical circuit is no longer closed and, therefore, the lamp cannot be switched on. ko 20 Summary of the invention

The present invention is directed to a device for protection! battery electrodes. The first embodiment of the invention. The device includes a spacer for moving the end of the battery away from the output electrode and an elastic conductor for effective spreading of the electrode to overcome the movement,

The device for the battery contains an electrically non-conductive spacer and an elastic conductor held by the spacer. The elastic conductor passes outwards from the spacer in the first direction so that the electrical contact (FI contact, which can beat, is reached both with the electrode of the connected battery and with the output electrode, from which the battery is displaced by the spacer. o The spacer has a hole that passes completely through it, and in which an elastic conductor is located.

The conductor is open on both sides of the hole and filled with an elastically compressible axially directed 60 hole.

In the second embodiment of the invention, the spacer is filled with a ring. As a spacer, a non-conductive ring with a diameter corresponding to the diameter of the battery case of the selected standard battery can be used. The spacer can be thick enough to exceed the spread of the central electrode protruding from the end of the battery. These ratios help in placing the device and avoiding shock effects on the electrode of a standard dry galvanic battery -D-

element

In the third, the invention is embodied in a device having an elastic conductor and a spacer, the conductor is defined by a central conductive element, elastic in design, and placed on the output Zzlectrode of the battery. The spacer is determined by the extension on the body, which passes at or above the height of the input electrode of the battery. An elastic conductor passes outward from that extension. The spacer has a cavity formed on the periphery of the hole for receiving an elastic conductor. The spacer is installed separately from the battery. The elastic conductor is filled in the form of two plate springs that are in electrical contact, passing through the diameter through the hole, and at least one of the plate springs 7/0 is bent so that! passes outward from the struts in an axial direction.

In the fourth embodiment of the invention, there is a pocket electric flashlight, in which batteries with a dry galvanic element are generally arranged in series. A pocket electric flashlight having a battery device according to the invention, which has a cylindrical shell with a plurality of batteries arranged in it in series, a front node at one end of the cylindrical shell with a 7/5 battery device installed between two batteries, without the device according to the invention such an arrangement can lead to damage of battery electrodes after an axial impact of a pocket electric flashlight. The device provides electrode protection.

Accordingly, the subject of the present invention is a device for protecting ordinary batteries with a dry galvanic element. Other purposes and advantages of the invention will be considered! below

As shown in fig. 1, many batteries 1 connections! sequentially in such a way that they form a column. This column could be installed inside the body or cylindrical shell of the 2nd 5" electrical device. Each battery 1 has a central electrode Z, which is generally a positive contact, and an output electrode 4, which is generally a negative contact with battery 1. The device, generally indicated by position 5, is placed in the middle between adjacent

GI batteries 1. Device 5 is also shown separately in fig. 2 and fig. 3.

The device 5 contains a spacer 6 and an elastic conductor 7. The spacer 6 has two opposite grooves 8 that accept the elastic conductor 7. The spacer is arranged in an annular shape with a hole passing completely through it. As shown, it forms a ring that can be installed inside the cylindrical shell of a pocket electric flashlight or the like. The ring b is given a certain size so that it rests against the end 9 of the battery case 10 for a battery of this standard size, and is thicker than the distance by which the central electrode C of a given size of a standard battery with a dry galvanic element extends beyond the end of the battery case . (F, Since such cylindrical shells 2 of the pocket electric flashlight are given a certain size in order to place specific galvanic elements 1. the ring 6 will also be accordingly located inside the cylindrical shell in 2. so that they rest against the ends 9 of the casings of 10 batteries.

The elastic conductor 7 is completely formed from a strip of metal sheet by bending. Two plate springs are formed essentially congruent with respect to each other, but slightly bent apart from each other in their middle part, as shown in fig. 3. The loop connects two definite plate springs. 65 The electrically conductive contact between electrodes Z and 4 of adjacent batteries 1 is provided by an elastic conductor 7. The conductor 7 is elastically deformed by adjacent batteries 1 in such a way that the elastic conductor 7 is pressed against electrodes Z and 4 in order to guarantee the corresponding contact.

Fig. 4 - 6 depict the second embodiment of the device for the battery, generally indicated by the position 11.

As shown in the drawings, the elastic conductor 12 is formed as a helical spring, which is created by stamping and notching round plates! in a spiral shape and by deforming it so that it is stretched in the direction of the axis of the spiral. Moreover, the round plate is punched in order to provide the annular edge 13. The spacer 14, in accordance with the second embodiment of the invention, is provided with an annular groove 15, into which the annular edge 13 is inserted.

As shown in fig. 4, part 14 of the spacer is placed in the middle between the ends of the 9 battery cases, as 7/0 was already mentioned when describing the first embodiment. The central electrode Z is pressed against the elastic conductor 12, which is formed as a spiral spring, i.e. to the same inner coil of springs, which has the smallest diameter. On the other hand, the input electrode 4 is pressed against one or more outer turns of the springs.

Fig. 7 shows a section of a pocket electric flashlight containing batteries 1 and a device 5 for /5 batteries, according to the first embodiment, located in the middle between batteries 1. Batteries 1 and device 5 are located inside the body 16 of the pocket electric flashlight, which contains a cylindrical shell 17, rear cap 18 and front assembly 19. To simplify the drawings, only two batteries are shown. Depending on the length of the pocket electric flashlight, a larger number of batteries 1 with corresponding devices 5 can be provided, for example, five batteries 1 with four devices 5 placed between them.

The rear cap 18 is equipped with a spiral electrical conductor 20, which is in contact with the output electrode 4 of the rear battery 1. On the other hand, the central electrode of the front battery 1 is brought into contact with the second spiral conductor 21. The conductor 21 is connected to it by means of the switch 22, schematically shown in Fig. drawings, to the first electrode 23 of the cylinder 24 s ov Lampochki. The first electrode 23 is connected to the filament 25 of the cylinder 24 of the light bulb. The filament 25, in turn, is electrically connected to the cartridge 26 of the cylinder 24 of the light bulb. The cartridge 26 is electrically connected to the housing 16 of a pocket electric flashlight made of aluminum. In the event that the switch 22 is closed, which could be done by pressing the button 27, the electric current can flow through the batteries 1 and the device 5 between them to the central electrode From the front battery 1 and further through the spring-shaped conductor 21 and the switch 22 through the electrode 23 , filament 25, cartridge 26, body 16 of the pocket electric flashlight, thread 28, rear cap 18 and spring-like rear conductor 20 in the output terminal 4 of the rear battery 1. When the switch 22 is closed, the light bulb emits light. Since the batteries 1 are in contact with each other by means of devices 5, and not directly by means of the electrodes of batteries 3 and 4, the batteries 1 are not deformed, and therefore a constant electrically conductive contact is ensured between the electrodes of 3 and 4 batteries 1.

Fig. 8 shows a section of a pocket electric flashlight having a similar design as the design shown in fig. 7. The same and similar elements are denoted by the same topics with the same positions, and their description is omitted to avoid repetition. The main difference between the embodiment shown in fig. 7 and 8, it is the fact that instead of the spring-like conductor 21, which contacts the central electrode of the front battery, an essentially inelastic conductor 7-3) with 36 is shown, which is brought into electrical contact by the device 5 of the front battery. This guarantees that there is no deformation of the central electrode Z and good conductive contact always;" is supported between the inelastic conductor 36 and the central electrode of the front battery 1 in the same way as if it is located between two adjacent batteries.

Fig. 9 shows the second embodiment, using batteries 32, designed in such a way that their central electrode 29 and output electrode 30 are protected from deformation. Elastic conductor 3! provides conductive contact between adjacent batteries 32, while electrodes 29 and 30 are separated from each other. The receiving space 33 in the form of a lid for placing the elastic conductor 31 is limited by the spacer 34, which is formed as an annular edge 34 surrounding the central electrode 29. The receiving space 33 in the form of a lid is closed by the output electrode of the adjacent battery 32. According to the illustrated embodiment, the elastic the conductor 31 is attached to the central zelectrode 29. However, the elastic conductor 31 can also be freely inserted into the receiving space Z3Z and elastically pressed against the adjacent zelectrodes 29 and 30.

Fig. 10, 11 and 12 depict the battery 32 separately. As shown in fig. 10, the elastic conductor 31 of this embodiment does not extend beyond the ring-shaped edge 34, since the outgoing electrode 34 extends into the receiving space 33 in the form of a cover. However, it is also possible that the output electrode 30 is (F), flat or even recessed, and the elastic conductor 31 protrudes beyond the ring-shaped edge 34 in order to make contact with the output electrode 30 of the adjacent battery 32. It is also possible that both the central electrode 29 and the output the electrode 30 is given the same shape, and both are provided with an elastic conductor 31. As can be seen from Figures 10 and 11, the elastic conductor 31 is somewhat similar to the elastic conductor 7 shown in the first embodiment. A similar embodiment of the battery 32 is shown in Figures 13 to 16. The same and similar elements are denoted by the same reference numerals, and their description is omitted to avoid repetition. , designated 65 by position 35. The elastic conductor 35 is similar to the elastic conductor 12 shown in the second view in the one shown in fig. 4-6. Moreover, although the output electrode 30 protrudes into the receiving space in the form of a cover, as shown in Fig. 13 and 14, the elastic conductor 35 protrudes beyond the spacer 34, as shown in Fig. 14.

Instead of providing the device for the battery shown in fig. 1 - b, batteries 32 with a non-removable device for a battery and an elastic conductor 31 or 35, shown in fig. 9 - 16, there may be fuses inside the pocket electric lanterns shown in fig. 7 and 8 to protect electrodes from deformation.

Despite the fact that the description of the preferred embodiment of the present invention, numerous modifications, changes, alternative embodiments and alternative material! may be examined by 7/0 specialists in this field of technology and may be used! in the embodiment of the present invention.

It is provided that all such alternative embodiments are considered to be within the scope of the present invention as defined by the attached claims.
