[0002] Description
[0003] Device for electrically conductive contacting of an electrical device
[0004] The invention relates to a device for electrically conductive contacting of an electrical device and to such an electrical device.
[0005] For the gait and health analysis of a horse or other hoofed animal (e.g., camel), it is desirable to record the reaction forces generated when the animal strikes the ground not just at a single point, but with a certain resolution across the impact area of the hoof. The measured values should allow conclusions to be drawn about the animal's state of health, e.g., regarding lameness or overloading of the gait.
[0006] While there are numerous solutions for corresponding tasks in the fields of medical diagnostics, training status analysis, and rehabilitation in humans, the availability of suitable systems for hoofed animals is limited. There is one commercially available product from the company Tekscan, as well as systems with a similar purpose, but these are based on measuring accelerations rather than reaction forces.
[0007] From GB 2482 192 B it is known to attach force sensors for such purposes to a horseshoe and to store their signals locally and / or to transmit them via a wireless transmitter to a remote receiving and evaluation station.
[0008] According to DE 102011 016 344 A1, force sensors are integrated into an elastomer body for a specific purpose. The elastomer body, which is intended to be inserted into a hoof boot, is designed to enable the use of commercially available resistive force sensors with their limited force measurement range for reaction force analysis in horses with their relatively high ground pressure.
[0009] US patent 2020 / 319044 A1 describes another system for the area-resolved measurement of reaction forces on the hooves of a hoofed animal, which transmits the sensor signals via a wireless transmitter to a remote evaluation unit. This system has a complex construction consisting of a base plate and a bottom plate, which are precisely aligned relative to each other. Between these plates are several force application cylinders and a number of resistive force sensors, as well as a microprocessor unit, a communication unit, and a battery to power the components. The function of the "force application cylinders" is not explained in the patent, nor is the method of attachment to the hoof described.
[0010] DE 102021 211 795 A1 describes a reaction force measuring plate for recording the ground reaction force distribution across the ground contact area of the foot of a hoofed animal or the foot of a person when it steps onto the ground, comprising a rigid support plate with a first surface facing the ground in use and a second surface facing the hoof or foot, a plurality of planar force measuring sensors fixed in position to the first surface of the support plate and several, in particular a plurality corresponding to the plurality of force measuring sensors, of elastic force transmission studs which are fixed to the free surfaces of the force measuring sensors.
[0011] DE 102023203 348 A1 describes a hoof boot system with a hoof boot having at least one sensor and a hoof boot wall with a hoof component holder and with an electronic hoof component, which is from 202403258 3
[0012] The hoof component holder is designed to read the sensors of the hoof boot. The electronic hoof component is permanently mounted in the hoof component holder and must be kept there, electrically connected via a charger, and recharged.
[0013] To establish an electrically conductive connection between a charger and a device to be charged, such as the electronic hoof component of the hoof boot system of DE 102023 203 348 A1, so-called connectors can be used, which serve to disconnect and connect, among other things, electrical conductors. The connecting parts can be joined by positive locking, by spring force, or magnetically detachable, allowing for quick and easy connection by plugging and unplugging. The electrically conductive contacts of the two connecting parts are typically fixed.
[0014] A disadvantage of connectors that use both positive and non-positive locking mechanisms is that one of the connecting parts, or rather its electrically conductive contacts, is exceptionally well-designed, while the other connecting part has a recess with its own electrically conductive contacts to hold the first connecting part securely and / or non-positively. Therefore, such connectors are only suitable for use in clean environments to prevent the recess of the second connecting part from becoming clogged, which could prevent the mechanical connection from functioning. Moisture can also penetrate the recess of the second connecting part and cause a short circuit.
[0015] Also known are spring contact pins, which are also referred to as spring contacts or spring pins, and represent contact elements which can be used, among other things, in detachable electrically conductive connections, for example in battery charging stations, battery compartments of mobile electronic devices. 202403258 4
[0016] Devices and similar applications. Electrical contact, i.e., closing an electrical circuit, is achieved in this case by touch or by probing using a spring-loaded pin. The contact is maintained by separate means, such as permanent magnets of opposite polarity on the two connecting parts.
[0017] A disadvantage of spring-loaded contact pins is that, due to the relative movement of the spring-loaded piston, which establishes the electrical contact, the fixed guide tube prevents a seal against dirt and, in particular, moisture. Therefore, spring-loaded contact pins are only suitable for use in clean environments.
[0018] A disadvantage of magnetically held connections, whether magnetic connectors or magnetic spring contact pins, is generally that they have or require a comparatively large area for contacting and holding, since the electrical contacts are usually located in the middle between the magnetic poles or the electrical contacts are surrounded by the magnetic poles, for example in a rectangular or ring shape.
[0019] One object of the present invention is to improve the possibilities for electrically conductive contact between electrical devices or electrical equipment. In particular, the possibilities for a secure connection between the devices or equipment are to be improved. In any case, this should be as dirt- and / or moisture-resistant as possible. In any case, this should be as simple, user-friendly, compact, cost-effective, lightweight, and / or intuitive to use as possible. In any case, this should be particularly suitable for the electrical charging of an electronic Huf component as described above. 202403258 5
[0020] At least an alternative to the known options should be created.
[0021] The object of the invention is achieved by a device and an electrical appliance having the features of the independent claims. Advantageous embodiments are described in the dependent claims.
[0022] Thus, the invention relates to a device for electrically conductive contacting of an electrical device, wherein the electrical device can also be an electronic device.
[0023] The device has an electrical supply connection with a first electrical contact and a second electrical contact, the two electrical contacts being configured and arranged to correspond to two electrical contacts of an electrical supply connection of the electrical device. This pair of electrical contacts allows for the establishment of an electrically conductive connection between the device or its electrical supply connection and the corresponding contacts of the electrical device's supply connection, enabling the transfer of electrical energy between the device and the electrical device. This transfer of electrical energy can serve to supply the electrical device with power from the device, or to charge an electrical energy storage device of the electrical device by means of the device, or vice versa.Additionally or alternatively, the transmission of electrical energy can also serve for signal transmission, whether unidirectional or bidirectional.
[0024] In any case, the device also has a third, preferably electrically insulated, contact, which is therefore not electrically conductive and cannot and should not contribute to electrical energy transmission as described above. Rather, the third contact serves as the mechanical contact between 202403258 6
[0025] Device and electrical equipment, as will be described in more detail below.
[0026] The three contacts form a triangle, with the three vertices being formed by the two electrically conductive contacts and the third electrically conductive or electrically insulated contact. This arrangement allows for a stable, i.e., tilt-proof, placement of the device on the electrical appliance or its housing, as will be described in more detail below. Making the third contact or contact point electrically conductive can increase design flexibility, particularly for signal and / or power transmission. Making the third contact or contact point electrically non-conductive or electrically insulated can minimize implementation effort. Using an isosceles or equilateral triangle, as will be described in more detail below, is a simple design choice. Technically, the three contacts can just as easily be connected with three different side lengths.
[0027] In other words, the three contacts in the middle define an area. A large area is preferred, as this can improve tilt stability. To keep the dimensions small, a good perimeter-to-area ratio is desirable. This would be maximized with an equilateral triangle. Alternatively, a ratio of at least 1:10, preferably 1:3 (isosceles), to the shortest side relative to the perimeter could be used.
[0028] Furthermore, the device has at least one magnet and / or a magnetic return, which is designed and arranged correspondingly to at least one, preferably oppositely polarized, magnet and / or a magnetic return of the electrical device in order to magnetically connect the device and the electrical device. A magnetic return can be achieved via a ferromagnetic object such as a piece of iron. This can represent a simple yet reliable type of connection, which can particularly avoid recesses or indentations in which dirt, moisture, and the like could accumulate and lead to clogging of the electrically conductive contacts and their corrosion. Instead of an oppositely polarized magnet of the electrical device, a metallic magnetic return can also be implemented there, which can increase the design possibilities.
[0029] Furthermore, the device is designed to make contact with the two contacts of the electrical supply connection of the electrical device and a third contact point on the electrical device via precisely these three contacts. This allows for the combination of electrical contact options and a secure and stable mounting, as previously mentioned.
[0030] According to one aspect of the invention, the three contacts form an isosceles or equilateral triangle, with the two electrical contacts forming the vertices of the base of the isosceles or equilateral triangle. This could represent a concrete implementation possibility.
[0031] According to a further aspect of the invention, the center point of the magnet and / or the magnetic return is arranged within the three contacts. This could represent a concrete implementation possibility. This could increase the stability of the magnetic connection.
[0032] According to another aspect of the invention, the centers of a pair of magnets and / or magnetic return paths are arranged between each of the two electrical contacts and the third contact. This can represent a concrete implementation possibility. This can increase the design possibilities. 202403258 8
[0033] According to a further aspect of the invention, the two magnets and / or the magnetic return paths are each arranged laterally outwards, preferably by a maximum of approximately 0.5 times, preferably by approximately 0.1 times, the distance between the two electrical contacts. This can represent a concrete implementation possibility.
[0034] According to another aspect of the invention, the two magnets are designed with opposite poles. This can define a predetermined orientation of the magnets of the device and the electrical appliance relative to each other.
[0035] According to a further aspect of the invention, the magnet and / or the magnetic return, preferably the pair of magnets, is arranged to be embedded in a housing from the outside. This can improve the sealing, particularly with regard to moisture or liquids, since the housing can be designed to be closed at this point.
[0036] According to a further aspect of the invention, the third contact is exceptionally well-designed in relation to a housing. This can enable or improve a point-like contact at this location.
[0037] According to a further aspect of the invention, the two electrical contacts are recessed relative to the housing. This can protect the electrical contacts from damage and abrasion.
[0038] According to another aspect of the invention, the device has a recess which is set back from a housing, wherein the two electrical contacts are protruding towards the recess, but preferably set back from the housing.
[0039] The highlighted arrangement of the two electrical contacts within a recess, which in turn is set back from the housing, allows the two electrical contacts to protrude and thus form a point shape, without allowing the two electrical contacts to protrude outwards beyond the housing at the same time, which could damage or wear out the two electrical contacts.
[0040] Preferably, by allowing the two electrical contacts to protrude only to such an extent that they remain recessed from the surroundings or the housing, electrical contact between two devices according to the invention can be prevented, as the respective electrical contacts cannot touch each other. This can improve safety when using the device according to the invention.
[0041] According to a further aspect of the invention, the recess is open towards an edge of the housing by means of a transition, preferably V-shaped. This can make it easier to remove dirt and the like that may collect in the recess, since the dirt can be pushed out of the recess laterally.
[0042] According to another aspect of the invention, the three contacts are fixed in place. This can improve the seal due to the lack of relatively moving components.
[0043] According to another aspect of the invention, the device is a charger for electrically charging the electrical device. This can represent a concrete way of implementing or using the present invention.
[0044] According to another aspect of the invention, the device is a cable for electrically connecting the electrical device. This can represent an alternative concrete way of implementing or using the present invention. 202403258 10
[0045] The present invention also relates to an electrical device, preferably an electronic Huf component, for electrically conductive contacting a device as previously described with an electrical supply connection having an electrical first contact and an electrical second contact, wherein the two electrical contacts are configured and arranged corresponding to two electrical contacts of an electrical supply connection of the device, with a housing configured to be contacted by a third, preferably insulated, contact of the device, wherein the two electrical contacts and the housing form a triangle, and with at least one magnet and / or a magnetic return, which corresponds to at least one, preferably oppositely polarized, magnet and / or a magnetic return.or a magnetic return of the device is designed and arranged to magnetically connect the electrical device and the device, wherein the electrical device is designed to be in contact with the three contacts of the electrical supply connection of the device by means of exactly the two electrical contacts and the housing.
[0046] This can represent a specific application for the device according to the invention as described above.
[0047] In other words, according to the invention, a monostable magnetic tripod can be created as an interface between a first electrical device, in particular in the form of a charger, and a second electrical device or electrical appliance, in particular in the form of a device to be charged. This generally establishes an electrically conductive connection between the two devices, which can serve in particular for the electrical charging of the second device by means of the first device. The electrical 202403258 11
[0048] Devices or equipment can also be electronic devices or equipment.
[0049] In any case, two contact points per device can be formed by non-spring-loaded loading pins, positioned opposite each other. A third contact point can be created between the housings of both devices, arranged in a triangular shape centrally above or below these. Thus, under normal circumstances, i.e., when in contact without force being applied, the two devices are only in contact at these three points.
[0050] At least one magnet per device can be inserted between the three support points. Opposite these points, at least one magnet with opposite polarity or a magnetic return path, such as a metal insert, can be integrated. Preferably, two magnets per device are used to increase the attractive force. The magnet pairs of the devices can be inserted with opposite polarities to enforce a defined alignment between the devices, since the magnets repel each other if misaligned.
[0051] Preferably, the centers of the magnets can lie within or near the imaginary triangle formed by the three support points. If the magnet centers are located externally, the distance between the centers of the magnets and the imaginary triangle between the support points can be a maximum of 0.5 times the distance between the charging pins.
[0052] Preferably, an overlapping connection is created between the devices, wherein at least two surfaces can overlap laterally, so that lateral pulling and / or rotational movement between the two devices can be prevented in at least two directions. 202403258 12
[0053] Preferably, a V-shaped contact surface can be created for the second device, so that the first device can pull itself into position in one direction and is only guided more closely by the V-shape in its final position.
[0054] On the first device, the housing can be raised at least locally, with some distance to the charging pins. This prevents two first devices, acting as chargers and electrically connected with an electrical voltage between the charging pins, from coming into electrical contact with each other when they approach and attract one another.
[0055] A local, e.g., mostly linear and not large-area raised area around the charging pins on the side of the first device as a charger can also offer the advantage that any dirt particles that may be present between the two devices do not lead to a loss of contact but are displaced by the raised areas when the first device is placed on the second device and can collect next to them.
[0056] The magnets can be installed internally, i.e., within the housing and thus sealed and not visible from the outside, or embedded externally into the housing of the devices. Preferably, a magnet on the side of the first device (the charger) can be positioned in front of the housing surface, particularly embedded externally into the housing surface, and on the side of the second device (the device to be charged) it can be positioned behind the housing surface. This ensures that, on the one hand, the distance between the magnets is kept as small as possible, and on the other hand, the magnet on the higher-value part (the device to be charged) can be protected by the housing.
[0057] An alternative design is possible as a bistable 3-legged device. Here, a fourth support point can be created opposite the first, with the two electrically conductive contacts forming the axis of symmetry between them. At least one additional magnet can be used as a charging pin on the side between the fourth support point and the axis of the two electrically conductive contacts.
[0058] The advantage here is that, in certain installation situations, a greater distance between the two magnets or magnet pairs can be achieved, which can improve the magnetic alignment between the two devices and thus their handling. A disadvantage compared to the previously described monostable tripod is that the second magnet generates a force that can reduce the holding force at the first contact point. This can lead to the user feeling that the first device, acting as a charger, is not "securely" or stably seated on the second device, which is the device being charged.
[0059] In any case, a very robust design without moving components can be achieved according to the invention. Deep recesses in both devices, where dirt could accumulate, can be avoided. Simple and intuitive handling can be achieved. The implementation can be very compact. The electrically conductive connection can be reverse polarity protected.
[0060] The present invention can be applied in a variety of ways to electrical connections for data or energy transmission. It is particularly suitable when an electrical connection, especially for charging, is required in harsh, humid, and / or dirty environments, particularly where space is limited. Examples of applications include sensory hoof boots for horses, performance or stress assessment in humans, integration into shoes (e.g., work shoes) for occupational health monitoring, performance or stress assessment in other animals (e.g., camel racing), and charging small devices in industrial environments. The present invention can also be used for devices that need to be charged underwater or in aggressive media.
[0061] Several embodiments and further advantages of the invention are explained below in connection with the following figures. Figure 1 shows a side view of a hoof boot including electronic hoof-

[0070] Magnets; and
[0071] Figure 9 shows a schematic representation of the charger's contacts with a magnet.
[0072] The above figures are described in Cartesian coordinates with a longitudinal axis X, a transverse axis Y perpendicular to the longitudinal axis X, and a vertical axis Z perpendicular to both the longitudinal axis X and the transverse axis Y, which corresponds to the direction of gravity. The longitudinal axis X can also be referred to as depth X, the transverse axis Y as width Y, and the vertical axis Z as height Z. The 202403258 15
[0073] The longitudinal axis X and the transverse axis Y together form the horizontal X, Y, which can also be referred to as the horizontal plane X, Y. The longitudinal axis X, the transverse axis Y, and the vertical axis Z can also be collectively referred to as the spatial directions X, Y, Z or as the Cartesian spatial directions X, Y, Z.
[0074] Figure 1 shows a side view of a hoof boot 15 including the electronic hoof component 25. Figure 2 shows a perspective view of Figure 1 from directly behind. Figure 3 shows a perspective view of the electronic hoof component 25 of Figure 1. Figure 4 shows a perspective top view from an oblique angle of the electronic hoof component 25 in the hoof component holder 15h of Figure 1.
[0075] In the exemplary embodiment considered, a hoof boot 15, acting as an outer protective element 15, accommodates a reaction force measuring plate (not shown) as a sensor. The plate has a closed, horseshoe-shaped, rigid support plate with a first surface and a second surface. Seven resistive force sensors, all with a rectangular base shape, are mounted on the first surface at equal intervals. The free surface of each force sensor points downwards towards a horse's hoof (not shown) and thus away from the ground (not shown). The force sensors 5 can also be referred to as force sensors 5 or force sensor elements 5. Such a reaction force measuring plate is known in principle from DE 10 2021 211 795 A1.
[0076] The reaction force measuring plate is located within the interior (not labelled) of the aforementioned hoof boot 15, which is made of an elastomeric material. The reaction force measuring plate is enclosed by the hoof boot sole 15a, which forms a flat, parallel surface on its underside, and extends upwards along its edges as the hoof boot wall 15c. The hoof boot sole 15a has a sole profile 15b facing downwards, away from the reaction force measuring plate. This seals the reaction force measuring plate off to the outside and thus protects it from external influences. 202403258 16
[0077] The force sensors are contacted and readable via printed sensor signal lines. A connection element in the form of a plug-in connector is provided for this purpose. The plug-in connector and an internal part of the connector are enclosed by a cable guard, thus protecting them from external influences. The plug-in connector exits through a cable opening in the connection element and is otherwise completely sealed by a spring-loaded cable clamp.
[0078] An electronic hoof component 25 is fixedly arranged on the outside of the hoof boot 15, facing laterally outwards in the transverse direction Y to the other hoof (not shown), and is connected to the force sensors via the connector. The electronic hoof component 25 is essentially enclosed externally by a housing formed by a front housing half 25a, facing away from the hoof boot wall 15c, and a rear housing half (not shown), facing the hoof boot wall 15c. The hoof component holder 15h is a single piece. The hoof component holder 15h accommodates the electronic hoof component 25 along a joining direction, which corresponds to the vertical direction Z in Figures 1 and 4. Then the hoof component holder 15h together with the incorporated electronic hoof component 25 is permanently connected to the hoof shoe 15 or to its hoof shoe wall 15c by means of screws 15k or rivets (not shown).
[0079] The electronic hoof component 25 has four display elements 37 in the form of light guides 37, which are arranged around a horseshoe symbol, representing the orientation of the hoof of the hoof, and are illuminated in such a way that the hoof on which the respective hoof boot system 15, 25 is used can be indicated. 202403258 17
[0080] The electronic hoof component 25 also has a control element 41 in the form of an on / off switch 41 to turn the electronic hoof component 25 on and off.
[0081] The electronic Huf component 25 further comprises a charging port 39 in the form of a pair of charging contacts 39, which serve to charge an electrical energy storage device (not shown) of the electronic Huf component 25. The charging port 39 has a first electrical contact 39a or contact point 39a and a second electrical contact 39b or contact point 39b, which are arranged next to each other. Along the vertical axis Z above the two electrical contacts 39a, 39b of the charging port 39, two magnets 40 are arranged as permanent magnets 40 within the housing or its front housing half 25a from the rear or from the inside, so that they are magnetically active externally but are liquid-tight, see also Figure 6. The two permanent magnets 40 have opposite polarities.
[0082] As already mentioned, the electronic hoof component 25 is inserted from above into the hoof component holder 15h and is held there by a protective rim 15i in a form-fitting and force-locking manner.
[0083] The front housing half 25a of the electronic hoof component 25 and the hoof component holder 15h form corresponding stop edges 15j, 43 as collars 15j, 43, which abut or rest against each other, thus improving the hold and also sealing against contamination. This achieves a firm hold of the hoof component holder 15h and the electronic hoof component 25, so that they can be permanently connected to the hoof boot 15 or its hoof boot wall 15c by means of screws or rivets. 202403258 18
[0084] The hoof component holder 15h is surrounded downwards, laterally, and forwards and backwards in a U-shape by a hoof component protector 15f. The hoof boot 15 can be opened and closed using a hoof boot fastener 15g to attach or remove the hoof boot 15 from the hoof.
[0085] Figure 5 shows a partial representation of the upper region of the electronic Huf component 25 of Figure 4 as an electrical device 25 with a connected charger 5 as a device 5 according to the invention, without the cable 51 shown. Figure 6 shows a section rotated by 90° through the representation of Figure 5. Figure 7 shows a top view from the rear of the charging device 5 of Figure 5. Figure 8 shows a schematic representation of the contacts of the charger 5 with two magnets 54. Figure 9 shows a schematic representation of the contacts 52a, 52b of the charger 5 with one magnet 54.
[0086] The charger 5 according to the invention has a housing 50 with a cable 51 as a connecting cable 51. The charger 5 further has an electrical supply connection 52 with an electrical first contact 52a and an electrical second contact 52b, wherein the two electrical contacts 52a, 52b are configured and arranged corresponding to the two electrical contacts 39a, 39b of the electronic Huf component 25 as the electrical device 25 to be charged. The charger 5 further has a third electrically non-conductive or electrically insulated contact 55. The three contacts 52a, 52b, 55 form an isosceles triangle with the two electrical contacts 52a, 52b as the vertices of the base of the isosceles triangle, in which either a single magnet 54 alone or two magnets 54 side by side can be arranged on the edges of the triangle, cf. Figures 8 and 9, which are each also permanent magnets 54.
[0087] In any case, the magnet(s) 54 are designed and arranged to correspond to and be opposite in polarity to the magnet(s) 40 of the electronic Huf component 25 202403258 19 in order to magnetically connect the charger 5 and the electronic Huf component 25. The charger 5 and the electronic Huf component 25 make contact precisely at these three points, specifically via the three contacts 52a, 52b, 55 of the charger 5 and the two contacts 39a, 39b of the electrical supply connection 3 of the electronic Huf component 25, as well as a third point on the front housing half 25a of the electronic Huf component 25. This ensures a consistently stable connection.
[0088] As already mentioned, a single magnet 54 can be used as a permanent magnet 54 by the charger 5, whereby only one magnet 40 would then be provided as a permanent magnet 40 by the electronic Huf component 25, cf. Figure 9. The single magnet 54 is then arranged within the isosceles triangle of the three contacts 52a, 52b, 55 in order to realize the desired stable connection.
[0089] Alternatively, as already mentioned, a pair of magnets 54 can be used as permanent magnets 54 to be arranged between each of the two electrical contacts 52a, 52b and the third insulated contact 55 of the isosceles triangle, cf. Figure 8. In this case, the two magnets 54 are each arranged laterally outwards by a maximum of approximately 0.5 times the distance A between the two electrical contacts 52a, 52b, see offset B of Figure 8.
[0090] In any case, the third insulated contact 55 of the charger 5 is excellently designed in relation to its housing 50 in order to achieve a point-like contact at this point.
[0091] The two electrical contacts 52a, 52b of the charger 5 are recessed relative to the housing 50. A V-shaped recess 53, open towards the edge of the housing 50 by means of a transition 53a, is provided in which the two electrical contacts 52a, 52b of the charger 5 are positioned, recessed relative to both the housing 50 and the recess 53. This allows the protruding electrical contacts 52a, 52b to be designed as point contacts and to make point contacts. Simultaneously, the two electrical contacts 52a, 52b are recessed relative to the housing 50 in such a way that two chargers 5 cannot make contact with each other or be electrically connected.
