Overload protection device for the protection of electrical components

The invention relates to an overload protection arrangement for protecting electrical components, comprising at least two electrical components, a carrier having several connection elements for connecting the electrical components, and at least one actuator according to the

Preamble of patent claim 1.

In the overload protection arrangement, the electrical components are each in a first position via a thermally softenable fixing to the

The carrier ensures that the connections of the electrical components contact the corresponding connection elements of the carrier. In the event of thermal stress, this is ensured.

Overloading the electrical components softens the thermally softenable fixing, and the electrical components are subjected to the force of the

The actuator is moved into a second position in which the electrical contact between the electrical components and the associated connection elements of the carrier is interrupted. The electrical components are thus electrically isolated in their second position.

Electrical components are generally only permitted within a certain range.

Electrical components must be operated within a specific voltage range and with a specific (maximum) current, i.e., within a rated operating range. Overstressing electrical components can cause them to operate outside their rated operating range. For example, the power dissipation at a damaged component, caused by reduced component insulation strength, can lead to impermissible heating of the component. If this impermissible heating of the component is not stopped and further heating prevented, it can lead to the complete destruction of the component. This can result in damage to materials and devices surrounding the component, and the formation of...

This can lead to smoke or fire hazards. Therefore, it is common practice to protect electrical appliances.

To assign thermal fuses to components in order to enable the shutdown of an electrical component in case of excessive heating.

The disconnection of overloaded electrical components has been implemented for years, particularly in surge protection devices. Surge protection devices have been used for decades in various designs to protect electrical circuits, systems, and machinery.

-2- LU508460 are used in rails and devices. Depending on the application and protection level, the surge protection arrangements feature different surge protection elements and different designs. Surge protection elements can include surge-limiting components such as varistors or transient absorber diodes (TVS diodes), as well as surge-switching components such as spark gaps or gas discharge tubes (GDTs), and combinations of these components. With varistors as surge protection elements, it is common to provide thermally activated disconnect devices. For gas discharge tubes, solutions are known that short-circuit the component after thermal overload, thus reducing the power dissipation in the overloaded gas discharge tube.

From DE 20 2011 110 007 U1 it is known to arrange a surge protection component, which may in particular be a varistor, on a carrier, wherein the two terminals of the varistor are each connected via a thermosensitive solder connection to a terminal element on the carrier and via this to the circuit to be protected.

Due to thermal overload of the varistor, the solder connections melt, and the varistor is moved into a second position by an actuator, which is primarily a spring element. In the second position, the varistor's terminals are disconnected from the terminals on the substrate, thus disconnecting the varistor from the circuit.

DE 10 2016 209 365 B4 discloses a separation device for two electronic components, each of which is attached to a carrier by a thermally softenable fixing, in particular a solder or an adhesive, wherein each electronic component is assigned a spring as an actuator. If a thermally accessible fixing softens due to impermissible heating of a component, the spring displaces the associated electronic component parallel to the carrier, so that the component, which is a varistor, a diode or a gas-filled

Surge arresters can act as electrically disconnected devices.

DE 10 2019 114 424 A2 discloses, in an embodiment, an overload protection arrangement as described above, with two surge protection elements, each of which is displaced along a carrier by a spring element when a thermally softenable fixing has broken due to heating of the surge protection element. Only one electrical contact is established between the surge protection element and

-3- LU508460 is disconnected from the associated terminal element of the carrier, while the other contact is maintained via a second terminal element. For this purpose, the second terminal element is designed in such a way that it allows the movement of the surge protection element from the first position to the second position, for example by changing its shape. This has the advantage that the surge protection element remains mechanically connected to the carrier via the second terminal element even in the second position, so that the surge protection element does not move uncontrollably in its surroundings, for example in a housing, after being disconnected on one side.

Based on this prior art, the invention aims to provide an overload protection arrangement that is particularly simple in design. In particular, the temperature-dependent isolation of several electrical components should be achieved as simply as possible.

This task is accomplished in the overload protection arrangement with the characteristics of the

Claim 1 is solved by the overload protection arrangement having at least one separating element which is slidably arranged on the carrier.

The separating element is subjected to a force by an actuator, such that the separating element is moved by the actuator from a first position to a second position.

The separating element interacts with two electrical components in such a way that, in the event of thermal overload caused by the separating element, the two electrical components can be moved into their second position when the thermal fixation softens, so that the electrical components are no longer held in their first position against the force of the actuator.

By using the disconnecting element, the force of one actuator can be transferred to two electrical components, so that only one actuator is required to disconnect two electrical components instead of two. The actuator can be, in particular, a spring element, preferably a compression spring, which exerts a force on the disconnecting element, at least in its first position. If a compression spring is used as the actuator, it is thus deflected against its spring force in the first position of the disconnecting element, i.e., compressed, while the compression spring is at least partially relaxed in the second position of the disconnecting element. Preferably, the disconnecting element and the

The actuator or spring element is arranged in such a way that even in the second position of the separating element a force – at least a small one – still acts on the separating element, so that the separating element is securely held in its second position.

-4- LU508460

Position is maintained.

It is stated at the outset that the overload protection arrangement comprises, in addition to a carrier, at least two electrical components, at least one actuator, and at least one disconnect element. In principle, the overload protection arrangement can only consist of two electrical components, one actuator, and one disconnect element.

have a separating element. Preferably, however, it is provided that the

The overload protection arrangement comprises n actuators, n isolating elements, and (2 x n) electrical components, where n > 2. The overload protection arrangement thus preferably comprises two actuators, two isolating elements, and four electrical components, wherein each actuator interacts with one isolating element and each isolating element with two electrical components.

A separating element thus simultaneously disconnects a pair of electrical components if the thermal fixation fails due to an impermissible

The heating process softens both components.

The electrical components that are disconnected by the at least one disconnecting element in the event of impermissible heating are in particular overvoltage protection elements, whereby overvoltage protection elements include both overvoltage-limiting components such as varistors or transient absorber diodes (TVS diodes) and overvoltage-switching components such as spark gaps or gas discharge tubes (GDTs).

Combinations of these components can be used.

A low-temperature solder is preferably used as a thermally softenable fixing agent. This solder melts or softens when the component in contact with it is subjected to thermal overload above a certain temperature. Preferably, the connections of the individual components in their first position (when the components are not overloaded) are each electrically and mechanically connected to a terminal element on the carrier via such a solder connection. Alternatively, an electrically conductive adhesive can also be used to connect the components.

Connections of the individual components are used with the associated connection element on the carrier.

According to a preferred embodiment of the invention, the two electrical components that interact with a separating element, and on which the force of an actuator acts, are thermally coupled. This results in the thermally softenable fixing of both electrical components being released in the event of a thermal overload of at least one of the two electrical components.

-5- LU508460

Components softened, so that both electrical components moved into their second position.

They can be moved to a different position. The thermal coupling of the two electrical components ensures that a thermally overloaded component is prevented.

The component is electrically disconnected, even if the other electrical component is disconnected.

The component that interacts with the thermally overloaded component and a separating element is not yet overloaded.

Furthermore, it is also possible that the thermally softenable fixing serves only for the mechanical fixing of the components to the substrate and not simultaneously for the electrical connection of the components. In this case, a thermally softenable fixing may be provided for one component or for a pair of components.

In the context of the present invention, the carrier is in particular designed as a printed circuit board in which the connection elements for the electrical components are connected to conductor tracks of the printed circuit board. The electrical components, in particular surge protection elements, can then be connected to the current or voltage to be protected via the conductor tracks of the printed circuit board.

The signal path is connected.

To prevent the two electrical components that interact with a separating element, or are moved by the separating element from their first position to their second position, from becoming electrically connected via the separating element, the separating element preferably consists of or incorporates an insulating material. In principle, it is sufficient if only the areas of the separating element that are in contact with the electrical components consist of insulating material. Alternatively, the separating element can also consist of two electrically conductive

areas each in contact with an electrical component, with the two electrically conductive areas separated by an area made of

The separating elements are insulated from each other by plastic. Preferably, however, the separating element consists entirely of an insulating material, so that the separating element is easy to manufacture, for example by injection molding.

According to an advantageous embodiment of the invention, the separating element has a receptacle at least for the part facing the separating element.

The actuator is mounted at the end of the circuit board. The receptacle, which can be shaped like a dome, for example, serves to hold the actuator in the desired position after it has been mounted on the circuit board. Furthermore, the receptacle allows for...

-6- LU508460 ensures that the actuator, in particular a corresponding spring element, reliably contacts the separating element even when the separating element is moved from its first position to its second position by the force of the actuator.

According to a further advantageous embodiment, the separating element has a support section for at least one section of the actuator, so that the actuator rests at least partially on the support section. This ensures that the actuator does not touch the surface of the support facing the actuator, even when the separating element is moved from its first position to its second position by the force of the actuator. This design of the separating element ensures, in particular, that an actuator does not come into contact with live components.

Sections on the substrate, for example, come into contact with conductor tracks of a printed circuit board. This makes it possible to use a simple metallic spring element for the actuator, without the spring element needing an insulating covering.

Advantageously, the at least one separating element is designed and arranged such that the separating element guides the two electrical components along the surface of the carrier from their first position to their second position. Preferably, the [missing information] also moves.

The separating element itself is essentially parallel to the surface of the support, which, due to the design of the separating element, leads to a corresponding

Movement of the electrical components parallel to the surface of the carrier. For this purpose, at least one guide element can be formed on the separating element, which corresponds to a guide element on the

The carriers work together.

The separating element is advantageously designed and arranged in such a way that the two electrical components are not only separated from their first position along a predetermined distance along the surface of the carrier.

The separating element not only moves the components into their second position, but also ensures that the two separated electrical components remain in their second position. This can be achieved, for example, by pressing the two separated electrical components against a stop or another component in their second position, so that the electrical components cannot move uncontrollably in their surroundings, for example, inside a housing.

-7- LU508460

To achieve the previously described guided movement of two electrical components, the separating element, according to a preferred embodiment, has two contact surfaces for the two electrical components on the side facing them. The dimensions of these contact surfaces are adapted to the corresponding end or side face of an electrical component, ensuring secure contact between the electrical components and the contact surfaces of the separating element. The two contact surfaces are preferably arranged at an angle α > 180° to each other, preventing the two electrical components from moving towards each other when they are moved from their first to their second position. Furthermore, recesses or ridges can be formed on the contact surfaces to additionally prevent movement of the electrical components perpendicular to the direction of movement of the separating element.

Alternatively or additionally, a separating element can be provided on the side of the separating element facing the two electrical components. This separating element keeps the two electrical components apart when they are moved from their first position to their second position. The separating element is arranged, in particular, between the two contact surfaces and can be web-shaped or pin-shaped. The two previously described configurations of the separating element, which can be implemented individually or together, ensure that there is no unintentional contact between the two electrical components, especially when moving them from the first to the second position.

In a preferred design, the separating element has an essentially U-shaped basic form. The back of the U-shape of such a separating element faces the two electrical components, so that the contact surfaces for the two components are located on the back of the U.

The components are formed. On the side of the U-shaped back facing away from the electrical components, the two U-shaped legs extend away from the electrical components. The U-shaped legs can be designed as guide arms that guide the separating element when moving it from its first position to its second position. If the separating element has a separating element, this is arranged on the side of the U-shaped back opposite the U-shaped legs and extends between the two electrical components.

-8- LU508460

According to a further advantageous embodiment of the previously described

The dimensions of the separating element, in particular the distance between the two guide arms or U-shaped legs, are selected such that the actuator is positioned between the two guide arms, at least in the first position of the separating element. Such a design of the separating element and arrangement of the actuator between the two

The guide arms allow for a very compact arrangement of the actuator and the

Separating element on the support. This also makes it possible for the

Separating element with its two guide arms on the actuator or on one of the

The actuator receiving bracket is guided, which reduces the number of components required.

As previously explained, the overload protection arrangement according to the invention preferably comprises not just two electrical components, but at least four electrical components arranged in pairs, such that each pair of components is assigned to a disconnect element. Furthermore, regardless of the number of electrical components, the overload protection arrangement preferably comprises a housing in which the carrier with the electrical components, the disconnect elements, and the actuators is at least partially arranged.

In particular, in an overload protection arrangement with two actuators, two disconnect elements and four electrical components, the overload protection arrangement, according to a particularly preferred embodiment, additionally has an indicator element, the position of which indicates whether at least one

The separating element or a pair of electrical components is arranged in the first or second position. The housing has a viewing window through which it can be seen whether the indicator element is in its first or second position.

The aforementioned display element is preferably designed as a slider, wherein the display element is arranged on the side of the electrical components facing away from the separating elements in such a way that the display element or the slider is moved from a first position to a second position when at least one of the two separating elements is moved into its second position due to a thermal overload of the two associated electrical components.

-9- LU508460

In this preferred embodiment, the display element is thus moved by the force of the actuators, which also apply force to the separating elements. Preferably, the force transmission occurs from an actuator via the associated separating element and the electrical components interacting with the separating element. In principle, the

However, force transmission can also occur from an actuator directly to the display element via the associated separating element. The separating element is then designed so that it is in contact with both associated electrical components as well as (directly) with the display element.

In detail, there are several ways to design and further develop the overload protection arrangement according to the invention. Reference is made to the dependent claims and the following description of preferred embodiments in conjunction with the drawing.

Figures 1 to 4 show a preferred embodiment of an overload protection arrangement 1 with a total of four electrical components 2, which are arranged on a carrier 3 designed as a printed circuit board. Figure 5 shows

- 10 - LU508460 also an enlarged section of the overload protection arrangement 1 according to

Fig. 1 with two electrical components 2. In the illustrated embodiment, the electrical components 2 are each a

The terminals 21 of the components 2 are each electrically and mechanically connected to corresponding terminal elements 31 on the carrier 3 via a solder connection as a thermally softenable fixing. In the representation according to FIGS. 1 to 4, the terminal elements 31 are located below the terminals 21 of the components 2, so that the terminal elements 31 are not visible in the figures.

Fig. 1 shows the state of the overload protection arrangement 1 in which all electrical components 2 are in their normal state, i.e., they are not excessively heated, so that the components 2 are in their first position, in which the terminals 21 are electrically and mechanically connected to the individual terminal elements 31 on the carrier 3 via the individual solder connections. The individual components 2 are thus electrically connected to the carrier 3 or its conductor tracks.

In addition to the four electrical components 2, two actuators 4 designed as spring elements, each arranged in a holder 5, and two separating elements 6 are arranged on the carrier 3. While the

The actuators 4 are fixedly mounted on the support 3 by their mountings 5, while the two separating elements 6 are each slidably mounted on the support 3.

Thus, the force F of one actuator 4 is transferred to two electrical components 2 by the separating elements 6, which are arranged between each pair of electrical components 2 and one actuator 4.

The terminals 21 of the components 2 are no longer connected to the terminal elements 31 on the carrier 3. Since the electrical components 2 have been moved into their second position in pairs by the separating elements 6, the two separating elements 6 are also in their second position.

Figure 6 shows a first embodiment of a single separating element 6 in a perspective view (Fig. 6a) and a top view (Fig. 6b). In the illustrated embodiment, the separating element 6, which consists of an insulating material, has a receptacle 61 for the end of the actuator 4 facing the separating element 6. This ensures that the actuator 4 is held in its position on the separating element 6 after its installation in the holder 5, even when the separating element 6 is in its second position. Thus, even in the second position of the separating element 6, at least a small force can still be applied to the separating element 6, thereby holding the separating element 6 in its second position.

Furthermore, the separating element 6 has a support section 62 for a

The actuator 4 is designed so that it does not touch the surface of the support 3, even when the separating element 6 is moved from its first position to its second position by the force F of the actuator 4. This ensures that the actuator 4, designed as a metallic spring element, does not have any stress-carrying sections on the support 4.

To ensure safe guidance of two electrical components by means of a separating element 6

To ensure that components 2 move from their first position to their second position, the separating element 6 has a position on its side corresponding to the two electrical components.

-12- LU508460 On the side facing the separating element 2, two contact surfaces 63 are provided for the two electrical components 2. From the top view according to Fig. 6b, it can be seen that the two contact surfaces 63 are arranged at an angle α to each other, which is slightly more than 180°. The two contact surfaces 63 are thus inclined slightly backwards from the center of the separating element 6, viewed in the direction of movement of the separating element 6 from its first position to its second position. In addition, a web-shaped separating element 64 is formed on the separating element 6 between the two contact surfaces 63, which extends between the two electrical components 2 abutting the separating element 6. This ensures that there is no unintended contact between the two electrical components 2 when they are moved from their first position to their second position.

The separating element 6 shown in Fig. 6 has an essentially U-shaped basic form. The U-shaped back 65 of the separating element 61 faces the two electrical components 2, so that the U-

The back 65 has two contact surfaces 63 for the two components 2. On the opposite side of the U-back 65, facing away from the electrical components 2, the two U-legs extend away from the electrical components 2. The separating element 64 is arranged on the side of the U-back 65 opposite the U-legs and extends between the two electrical components 2.

The U-shaped legs are designed as guide arms 66, 67, which serve to guide the separating element 6 when moving it from its first position to its second position. For this purpose, the guide arms 66, 67 of a separating element 6 slide with their inner surfaces against the outer surfaces of the holder 5 of the

along the actuator 4, as can be seen from Figs. 1 to 4. The bracket 5 and the actuator 4 are thus arranged between the guide arms 66, 67 of a separating element 6, which enables a very space-saving arrangement of the two actuators 4 with their respective bracket 5 and the two separating elements 6 on the carrier 3.

As can be seen in Figures 6a and 6b, one guide arm 66 is longer than the other guide arm 67. The different lengths of the guide arms 66 and 67 can be used as a positioning aid for the separating element 6, so that the separating element 6 is in a predetermined orientation on the

Carrier 3 is mounted. In addition, the greater length of one guide arm 66 can be used to actuate a microswitch (not shown in the figures) arranged on the carrier 3, so that via the

-13- LU508460

A microswitch can provide an electrical indication of whether a disconnect element 6 is in its first or second position. Such a microswitch thus enables remote indication of whether a pair of electrical components 2 has been disconnected or not.

Fig. 7 shows a second embodiment of a single separating element 6 in perspective view (Fig. 7a) and in top view (Fig. 7b).

In contrast to the embodiment shown in Fig. 6, this separating element 6 has no separating element arranged between the two contact surfaces 63. Instead, the separating element 6 shown in Fig. 7 has a significantly extended support section 62 for a section of the actuator 4, compared to the support section 62 of the separating element 6 according to Fig. 6.

Furthermore, the two guide arms 66, 67 of the separating element 6 according to Fig. 7 have the same length.

The overload protection arrangement 1 shown in Figs. 1 to 4 also includes a

Housing 7, in which the carrier 3 with the electrical components 2, the

Actuators 4 and the separating elements 6, as well as a display element 8, are at least partially arranged. A viewing window 71 is formed in the housing 7, through which it is possible to see from outside the housing 7 whether the

Display element 8 is in its first position (Fig. 1) or in its second position (Figs. 2 to 4). Display element 8 is designed as a slider with a display section 81 that is pushed in front of the viewing window 71 when at least one of the two pairs of components 2 or one of the two separating elements 6 is moved from the first to the second position. Display element 8 thus indicates whether all electrical

Components 2 are electrically connected (Fig. 1) or at least one

A pair of components 2 has been separated due to impermissible heating (Figs. 2 to 4).

The display element 8 is arranged on the side of the electrical components 2 facing away from the separating elements 6 in such a way that the display element 8 is moved from a first position to a second position when at least one of the two separating elements 6 is moved due to a thermal

Overload of the two associated electrical components 2 is moved into its second position. Furthermore, the indicator element 8 is arranged in relation to the electrical components 2 in the housing 7 such that the components 2 in their second position are held against the by the associated separating element 6.

Display element 8 must be pressed so that the components 2 are in their second position.

-14- LU508460

The display element 8 also has a flexible retaining element 82 that interacts with the separating elements 6 such that the display element 8 is held in its first position when both separating elements 6 are in their first position. For this purpose, the separating elements 6 have retaining sections 68 against which the retaining element 82 rests, as can be seen in Fig. 1. Because the retaining element 82 is flexible, the display element 8 can slide past the second separating element 6 when one separating element 6 is moved from its first position to its second position, even if the second separating element 6 remains in its first position (Figs. 2 and 3). For this purpose, the corresponding retaining sections 68 have

The separating elements have 6 rounded corners, so that the retaining element 82 can slide more easily past the retaining sections 68.
