Description

TECHNICAL AREA

The present invention is in the field of power transmission technology and relates to a switch arrangement.

BACKGROUND

Switch assemblies for providing and preventing current flow are used in different areas. One example is packaging with electronic components.

When equipping packaging with electronic components, turning it on at the right time is crucial. In the optimal case, a switch of the switch assembly switches exactly when the package is opened. Packaging is often stored for long periods of time and in undefined locations before being sold or opened. If electricity is already flowing during storage, the battery can be drained. For this reason, it is important that no electricity flows during storage. Common systems for providing and inhibiting power flow associated with packaging include REED switches and "greeting cards" shifters.

With REED switches, a magnet located in the packaging lid opens the REED switch in the packaging body so that no current flows. When the lid is opened, the magnet moves away from the switch and the circuit is closed. The disadvantage of this system is the high cost of a REED switch, especially in the surface-mounted device (SMD) area, and prevents its widespread use in the price-sensitive packaging market.

In "greeting card" pushers, the two contacts of the switch are separated by a cardboard or plastic strip. When opening, either a conductive slide between the Slid contacts, or remove an insulating slider between the contacts. A disadvantage of these systems is that the construction is complicated and that the slider is usually visible in the fold.

An example of a switch arrangement for activating and deactivating an LED is shown in FIG US2006 / 0250790 known. This switch assembly comprises two movably arranged batteries that can be brought into contact by means of a slider to activate a current flow.

SUMMARY OF THE INVENTION

The present invention is based on the object to provide a simply constructed and inexpensive switch assembly available, with the premature battery drainage can be reliably prevented.

This object is achieved by a switch arrangement according to claim 1 and by a switch arrangement according to claim 3. Advantageous developments and embodiments are specified in the independent claims.

A first switch arrangement according to the invention can be used to provide and prevent a current flow and comprises a battery having a first pole and a second pole, a first line electrically connected to the first pole of the battery, a second line, and a first magnet and a second magnet. The battery is reciprocable between a first battery position in which there is no electrical contact between the second pole of the battery and the second line and a second battery position in which the second pole of the battery is in electrical contact with the second line , The first magnet is reciprocable between a first magnet position and a second magnet position, the first magnet, when in the first magnet position, holding the battery in the first battery position and, when moving from the second magnet position to the first magnet position is moved, the battery moves from the second battery position to the first battery position. The second magnet is arranged to hold the battery in the second battery position when the first magnet is in the second magnet position and to remove the battery from the first battery position in FIG the second battery position moves when the first magnet is moved from the first magnet position to the second magnet position.

In other words, the first magnet, when in the first magnet position, can hold the battery in a first battery position via a magnetic force or magnetic interaction with the battery, in which there is no electrical contact between the second pole of the battery and the second one Line exists. When the first magnet is removed from the first magnet position and transferred to the second magnet position, the magnetic force applied to the battery by the first magnet decreases. This allows the magnetic force exerted by the second magnet on the battery to move the battery to the second battery position, thereby establishing electrical contact between the second pole of the battery and the second line. As long as the first magnet is in the second magnet position, the second magnet can ensure the electrical contact between the second pole of the battery and the second line. When the first magnet is in the first magnet position, the magnetic force that the first magnet exerts on the battery is stronger than the magnetic force that the second magnet exerts on the battery, such that the battery is moved into the first magnet by the magnetic force of the first magnet Battery position is moved or held in the first battery position. In contrast, when the first magnet is in the second magnet position, the magnetic force that the first magnet exerts on the battery is weaker than the magnetic force that the second magnet exerts on the battery, so that the magnetic force of the second magnet in the second battery position is moved or held in the second battery position.

The switch assembly according to the invention thereby makes it possible to reciprocate the battery by moving the first magnet back and forth, whereby a current flow can be switched on and off.

The switch is opened and closed by a movement of the battery, which is triggered by external magnetic forces. Because the battery is a comparatively large component with a lot of metal material, a comparatively high magnetic force can be exerted on it. Thereby, the respectively desired battery position and the electrical contact can be securely held and manufactured, so that the states with and without current flow with great certainty and time accurately manufactured and can be reliably maintained. in the opened state of the switch so the current flow can be safely prevented to effectively avoid unwanted emptying of the battery.

In addition, the switch assembly according to the invention comes out with very few components. The battery can be used not only for power supply but also as a movable switch element, so that this component can be used very efficiently. In comparison with other switch arrangements, for example a circuit board equipped with a switch and with a battery, the switch arrangement according to the invention has a simpler structure and essentially requires only one battery, two magnets and two lines as main components.

In addition, the components of the switch assembly are available at low cost and / or produced, so that the switch assembly according to the invention with its few and cheap components that do not require complex electronics or printed circuit boards, is very inexpensive. This is for example very advantageous in the price-sensitive packaging segment, but also in other applications.

Because the current flow is switched on and off not mechanically, but magnetically, the switch assembly is more robust against external interference.

In addition, the first magnet may also be completely removed from the remainder of the switch assembly and need not be mechanically coupled to or connected to the remainder of the switch assembly. As a result, a major disadvantage of the aforementioned "greeting card" slider systems can be avoided, in which the slide must be connected to the lid.

According to an advantageous development, the first switch arrangement according to the invention further comprises a third line, wherein, when the battery is in the first battery position, the second pole of the battery is in electrical contact with the third line, and when the battery is in the second battery position is located between the second pole of the battery and the third line is no electrical contact. Thus, in the first battery position and in the second battery position, the second pole of the battery is in each case electrically connected to a different line (in the first battery position with the third line, in the second battery position with the second line), so that this embodiment can be used as a changeover switch.

A second switch arrangement according to the invention comprises a battery having a first pole and a second pole, a first line, which is electrically connected to the first pole of the battery, a second line and a first magnet. The battery or the second conduit is reciprocable between a respective first position and a respective second position, wherein when the battery or the second conduit is disposed in their respective first position, no between the second pole of the battery and the second conduit electrical contact exists, and, when the battery or the second line is disposed in its respective second position, the second pole of the battery is in electrical contact with the second line. The first magnet is reciprocable between a first magnet position and a second magnet position, wherein the first magnet, when in the first magnet position, holds the battery or the second lead in their respective first positions and, if from the second Magnetic position is moved to the first magnetic position, the battery or the second line moves from their respective second position to their respective first position, or the first magnet when it is in the first magnet position, the battery or the second line in their respective second position and, when moved from the second magnet position to the first magnet position, moves the battery or the second line from their respective first position to their respective second position.

Accordingly, unlike the first switch arrangement according to the invention, the second switch arrangement according to the invention can also switch via a movement of the second line, so that the battery does not necessarily have to be movable. Another difference is that according to an alternative, the first magnet in the first magnet position can hold the battery or the second line in the second position as well. The first magnet can thus also actively establish or ensure the electrical contact or current flow instead of only actively preventing the electrical contact or current flow, as in the first switch arrangement according to the invention or as in another alternative of the second switch arrangement according to the invention. Therefore, the first magnet can also be used to close the switch and not just to open it. Another difference is that the second switch arrangement according to the invention does not necessarily require a second magnet. When the first magnet is in the second magnet position, the That is, closing or opening can also be done using another force, such as gravity or spring force, rather than using a magnetic force from a second magnet.

In some embodiments, the second switch assembly according to the invention further comprises a second magnet arranged such that in the event that the first magnet in its first magnet position holds the battery or second lead in their respective first positions, the second magnet holds the battery When the first magnet is in the second magnet position, the second magnet moves the second lead from its respective first position to its respective second position when the first magnet is in the second position first magnetic position is moved to the second magnetic position, or that, in the case that the first magnet in its first magnet position holds the battery or the second line in their respective second position, the second magnet, the battery or the second line in their respective holds first position when the first magnet in the second magnet tion and the second magnet moves the battery or the second line from their respective first position to their respective second position when the first magnet is moved from the first magnet position to the second magnet position. In these embodiments, therefore, the second magnet can make contact and ensure or break the contact and ensure the break in contact when the first magnet is in the second magnet position.

In some embodiments, the second switch assembly according to the invention further comprises a third lead arranged to be in electrical contact in those of the first and second positions of the battery with the second pole of the battery in which the second lead is not in contact with the second pole the battery is in electrical contact, and it is not in electrical contact with the second pole of the battery in the other of the first and second positions of the battery. As a result, these embodiments can be used as a changeover switch.

For example, in some embodiments of the first and second switch assemblies of the invention, the battery may be a button cell, a flat battery, or a printed battery. Button cells are standard components that are readily available, inexpensive and very compact.

In some of these embodiments, button cells having a diameter of 30 mm and a thickness of 1.6 mm or 2.3 mm are used. These are button cells of the type 3016 or of the type 3023, which, for example, offer a good compromise between compactness and voltage for packaging applications.

In some embodiments of the invention, the first magnet and / or the second magnet is a permanent magnet.

Preferably, the first magnet has a higher magnetic flux density than the second magnet. As a result, it can be well ensured that the first magnet attracts the battery more when it is in the first position than the second magnet. Thereby, the switch assembly can be securely held in the open or de-energized state, so that premature or unwanted emptying of the battery can be effectively prevented. Additionally or alternatively, the magnetic force between the first magnet and the battery and / or between the second magnet and the battery can also be adjusted over the respective distance to the battery, instead of the respective strength of the magnet.

In such embodiments, where the first magnet and / or the second magnet is a block magnet, the block magnet may have an edge length of A x B x C, where 3 mm ≦ A ≦ 100 mm, 1 mm ≦ B ≦ 100 mm and 1 mm ≤ C ≤ 30 mm.

According to one or more embodiments of the invention, the first line, the second line and / or the third line comprises carbon, silver, aluminum, copper, steel and / or iron or consists of carbon, silver, aluminum, copper, steel and / or iron. Alternatively or additionally, the first line can be permanently and permanently connected to the battery. This can improve the robustness and reliability of the switch assembly.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Figures 1A and 1B show a switch assembly 10 according to the invention according to a first embodiment. The switch assembly 10 includes a first magnet 12 and a second magnet 14, each in the form of a disc magnet. The first magnet 12 is thicker than the second magnet 14 and has a larger diameter than the second magnet 14, so that the first magnet 12 has a higher magnetic flux density than the second magnet 14 and is stronger. In the embodiment of the Figures 1A and 1B For example, the first magnet 12 has a diameter of 10 mm and a thickness of 0.6 mm, and the second magnet has a diameter of 1.5 mm and a thickness of 0.5 mm. In this embodiment, both magnets 12 and 14 are made of neodymium. It should be understood that in other embodiments magnets 12 and 14 may have other dimensions and may be made of other materials.

The switch assembly 10 of Figures 1A and 1B further comprises a battery 16 in the form of a button cell, and a first line 18 and a second line 20. The battery 16 includes a positive pole and a negative pole, wherein the first line 18 with the positive pole electrically connected. In other embodiments, the first lead 18 may be connected to the negative terminal instead of the positive terminal.

As in the Figures 1A and 1B is illustrated, the switch assembly 10 is integrated into a package 22. The package 22 includes a body 24 and a closure member 26 in the form of a lid. In other embodiments, the closure member 26 may be configured differently and formed, for example, by a flap.

The first magnet 12 is connected to or included in the closure member 26 so that the first magnet 12 is moved from a first magnet position to a first one by removing the closure member 26 from the body 24 or by relatively moving the closure member 26 with respect to the body 24 second magnetic position can be moved.

In Figure 1A in which the closing element 26 on the body 24 on or rests, so that the package 22 is closed, the first magnet 12 is in the first magnet position. In FIG. 1B in which the closing element 26 is removed from the body 24, the first magnet 12 is in a second magnet position. In the Figure 1A the battery 16 is in a first battery position, in which the negative terminal of the battery 16 is spaced from the second line 20, so that between the negative pole of the battery 16 and the second line 20 is no electrical contact. In FIG. 1B the battery 16 is in a second battery position, in which the negative pole of the battery 16 and the second line 20 are in electrical contact.

In Figure 1A the package 22 is closed, ie the body 24 is closed by means of the closing element 26. In this arrangement, the first magnet 12 is in the first magnet position and exerts a magnetic force on the battery 16 which is stronger than the magnetic force applied to the battery 16 by the second magnet 14. This magnetic force applied to the battery 16 by the first magnet 12 keeps the battery 16 in the first battery position. Because the battery 16 is in electrical contact with only the first conduit 18 but not the second conduit 20 in the first battery position, the switch assembly 10 is open so that no current can flow.

By removing the closure member 26, the first magnet 12 can move from the first magnet position to the second magnet position, as in FIG FIG. 1B is shown to be moved. Thereby, the magnetic force that the first magnet 12 exerts on the battery 16 can be reduced below the magnetic force that the second magnet 14 exerts on the battery 16. Therefore, due to the now relatively higher magnetic force between the battery 16 and the second magnet 14, the battery 16 is moved from the first battery position to the second battery position. Thereby, the battery 16 is brought into electrical contact with the second line 20, so that a current can flow. By re-closing the package 22, the first magnet 12 can again be brought into the first magnet position, in which the force of the first magnet 12 on the battery 16 is stronger again than the force of the second magnet 14 on the battery 16. Thus, the Battery 16 from the second battery position (in Fig. 1B shown) again in the first battery position (in Fig. 1A shown) moves and lifted the electrical contact to the second line 20, whereby the current flow is interrupted.

In the embodiment of the Figures 1A and 1B , as well as in the other illustrated embodiments of Figures 2 and 3 , the first lead 18 is firmly and permanently connected to the battery 16. As a result, the first line 18 during the back and forth movement of the battery 16 at least partially in the region of the battery 16 is also moved back and forth. Due to the fixed and permanent connection of the electrical contact to the first line 18 can be ensured regardless of the battery position. This allows the magnets 12 and 14 to be used only to prevent electrical contact between the battery 16 and the second lead 20, so that the magnets 12 and 14 are not used for adjustment of contact with the first lead 18 Need to become. The battery contact to the first line 18 can thus be independent of the respective arrangement of the magnets 12 and 14, whereby the switch assembly 10 can be made more robust and reliable.

In the embodiments shown, the first line 18 may, for example, be printed on a flexible plastic film, so that in the aforementioned solid, permanent contact or the solid, permanent connection between the first line 18 and the battery 16, the joint mobility of the battery 16 and a Section of the first line 18 can be achieved via the elasticity of the plastic film.

The second conduit 20 and the second magnet 14 are immovably disposed with respect to the body 24 in the embodiments shown, but may be used in other embodiments also be mobile. The battery 16 and a portion of the first conduit 18 adjacent to the battery 16 are in FIG FIGS. 1A and 1B movably arranged with respect to the body 24. The first magnet 12 is in the Figures 1A and 1B firmly connected to the closure member 26, and thus immovable with respect to the closure member 26. Thereby, the first magnet 12 can be moved together with the closing element 26 with respect to the body 24 and thus with respect to the other components of the switch assembly 10, namely the components 14, 16, 18 and 20. In other, not shown embodiments, however, the first magnet 12 may be movable within the closing element 26 or also on the closing element 26.

It should be noted that in the embodiments shown, the FIGS. 1 to 3 , As well as in embodiments not shown, not necessarily each have to give only a first and second magnetic position, but that there may be more in each case. For example, the first magnet positions may be arranged within a range and may correspond to any position outside this range of a second magnet position. When the first magnet 12 is moved outside of this range from within this range, this corresponds to moving the first magnet 12 from the first magnet position to the second magnet position, and vice versa. The position of this area is characterized in relation to the switch assembly 10. For example, this area may correspond to the interior area of an imaginary sphere around the first and / or the second battery position. The radius of this ball may depend on the relative magnitude of the magnetic flux density of the first magnet 12 and the second magnet 14 to each other and the distance between the second magnet 14 and the battery 16.

FIGS. 2A and 2B show a modification of the invention in the Figures 1A and 1B illustrated embodiment. In contrast to the embodiment of Figures 1A and 1B is in the embodiment of FIGS. 2A and 2B the battery 16 is not arranged flat between the first and the second magnet 12, 14, but upright, so that the axis passing through the plus and minus pole of the battery axis perpendicular - and not parallel - to that axis along which the first magnet 12 and the second magnet 14 are arranged. This will, as in the FIGS. 2A and 2B 6, the electrical contact with the second line 20 is made across a side surface of the battery 16 and not across a battery area opposite that battery area where the battery 16 is connected to the first line 18.

The functioning of the in the FIGS. 2A and 2B The circuit arrangement shown corresponds to that, as with respect to the Figures 1A and 1B has been described. Accordingly, located in FIG. 2A the first magnet 12 in a first magnet position and the battery 16 in a first battery position and are located in FIG. 2B the first magnet 12 in a second magnet position and the battery 16 in a second battery position.

In the further embodiment of the invention FIGS. 3A and 3B The closure element 26 has an angled shape and the battery 16 is arranged in a corner region of the body 24. The first and the second line 18 and 20 extend on a side wall of the body 24 in sections next to each other, wherein the side wall is perpendicular to a plane defined by the battery 16 level. The plus and minus pole of the battery 16 are together with the first magnet 12 and the second magnet 14 on a common axis, ie the battery 16 is according to the embodiment of Figures 1A and 1B arranged flat between the magnets 12 and 14.

In the FIG. 3A the first magnet 12 is in the first position of the magnet according to the preceding description and thus holds the switch arrangement 10 in the open, de-energized state. In FIG. 3B For example, the closure member 26 has been displaced relative to the body 24 so that the first magnet 12 is in the second magnet position and the battery 16 is held in the second magnet position by the second magnet 14 and contacts the second conduit 20 therein. In FIG. 3B Accordingly, the switch assembly is in the closed state in which a current flows.

FIGS. 4A and 4B show a further modification of the invention in the Figures 1A and 1B illustrated embodiment of the switch assembly 10, which in FIG. 4A in the open state (no electrical contact between the battery 16 and the second line 20) and in FIG. 4B in the closed state (electrical contact between the battery 16 and the second line 20) is shown. In this embodiment, the first conduit 18 and the second conduit 20 extend within an environment of the battery 16 substantially in a common direction indicated by the double arrow in FIG Fig. 4A is shown. In this case, the first line 18 projects beyond the second line 20 in this direction and the protruding part of the first line 18 is connected to the battery 16. When the first magnet 12 is in the first magnet position ( Fig. 4A ), the first magnet 12 and the second Magnet 14 a distance which is larger than a dimension of the battery 16 along a connecting direction of the magnets 12 and 14. The connecting direction of the magnets 12 and 14 differs only slightly from the aforementioned direction of the double arrow. When the first magnet 12 is in the first magnet position, the first lead 18 is stretched toward the first magnet 12 so that the battery 16 is spaced from the second lead 20. When the first magnet 12 is brought from the first to the second magnet position, the battery 16 slides along the direction of the double arrow toward the second magnet 14, which is located behind an end portion of the second conduit 20, and is by the force of the second magnet 14 brought into electrical contact with the second line 20. When sliding sideways, the first conduit 18 is compressed and folded accordion-like within a buffer zone (cf. Fig. 4B ).

Switching can therefore not only by means of a pivoting or folding movement (as in FIGS. 1A and 1B is shown) and a roll-off (as in FIGS. 2A and 2B shown), but also (as in FIGS. 4A and 4B is shown) via an upsetting and stretching movement of the first conduit 18 or via a sliding movement of the battery 16. The switching is not limited to the types of movement shown, but may include other types of movement in other embodiments, not shown.

FIGS. 5A and 5B show a further inventive embodiment of a switch assembly according to the invention, which, unlike the embodiments described above, does not comprise a second magnet 14. In FIG. 5A the first magnet 12 is in the first magnet position and prevents electrical contact between the battery 16 and the second line 20. When the first magnet 12 is brought into the second magnet position (in FIG Fig. 5B shown), then the force of gravity of the battery 16 exceeds the magnetic force between the battery 16 and the first magnet 12, so that the battery 16 is brought into electrical contact with the second line 20 by gravity.

Figures 6A and 6B show a further embodiment of the invention comprising an additional third line 28. In this embodiment, the first line 18 is electrically connected to a first pole of the battery 16. In FIG. 6A is the first magnet 12 of a first magnetic position in which it holds the battery 16 in a position in which the second pole of the battery 16 is electrically connected to the third line 28 and is electrically isolated from the second line 20. When the first magnet 12 is in the second magnet position is brought (in Fig. 6B shown), then the magnetic force between the battery 16 and the second magnet 14 exceeds the magnetic force between the battery 16 and the first magnet 12. By the magnetic force of the second magnet 14, the battery 16 is moved to another position in which the second pole the battery 16 is electrically connected to the second line 20 and is electrically isolated from the third line 28. This embodiment can be used as a changeover switch.

FIGS. 7A and 7B show a further embodiment of the invention in which the first magnet 12 is used to close the switch assembly and to hold the switch assembly in the closed state. In FIG. 7A the first magnet 12 is in a first magnet position, in which it holds the battery 16 in a position in which the second pole of the battery 16 is electrically connected to the second line 20. Because the first lead 18 is electrically connected to a first pole of the battery 16, a current may flow and the switch assembly is closed. When the first magnet 12 is brought to the second magnet position (in FIG Fig. 7B shown), then the magnetic force between the battery 16 and the second magnet 14 exceeds the magnetic force between the battery 16 and the first magnet 12. By the magnetic force of the second magnet 14, the battery 16 is moved to another position in which the second pole the battery 16 is electrically isolated from the second line 20. This embodiment thus switches with a movement of the first magnet 14 opposite to the embodiment of FIG Figures 1A and 1B ,

Figures 8A and 8B show a further embodiment of the invention, in which not the battery 16 but the second line 20 is moved to switch. In this embodiment, the battery 16 is immovable relative to the body 24 of the package 22. The second magnet 14 is fixedly and permanently connected to a movable portion of the second line 20. In Figure 8A is the first magnet 12 of a first magnetic position in which it holds the second line 20 in a position in which the second pole of the battery 16 and the second line 20 electrically via a magnetic interaction between the first magnet 12 and the second magnet are separated. When the first magnet 12 is brought to the second magnet position (in FIG Fig. 8B shown), then the magnetic force between the battery 16 and the second magnet 14 exceeds the magnetic force between the second magnet 14 and the first magnet 12. By the magnetic force of the second magnet 14, the second line 20 with the second pole of the battery 16 in electrical Brought in contact.

It should be understood that the detailed embodiments described for the present invention are exemplary only and not limiting. The scope of the present invention is determined solely by the claims.
