Definitions
- fuses and/or relays are usually used to protect the electrical components or the on-board network.
- security technology in particular is developing to the extent that essential components are dependent on a constant, reliably available power supply.
- a replacement overcurrent protection for securing a circuit for a fuse box, in particular in a vehicle comprising:
- At least two electrical contacts which are arranged at a defined spatial distance from one another, the circuit being able to be closed by an electrical connection of the at least two electrical contacts, the defined spatial distance corresponding to a grid spacing of a fuse or a relay.
- a fuse box should be understood as a container for one or more fuses. This is described in more detail in connection with the fuse box according to the invention.
- a vehicle can in principle be any vehicle with at least one electrical circuit. This can in particular be at least an air, water or land vehicle. It can be provided that the vehicle is designed as a motor vehicle, in particular as a passenger car or truck.
- the isolating circuit is designed to be purely electrical.
- the isolation circuit may be free of mechanical components suitable for isolating the circuit.
- the triggering characteristic is determined solely by the electrical components.
- the isolating circuit has at least one electromechanical component which is suitable for interrupting the circuit, which is in particular installed redundantly to a purely electrical component.
- an electromechanical component is understood to mean, in particular, fuses and relays.
- Another electromechanical component offers the advantage that the excellent tripping characteristics of the electrical component are supplemented by a redundant fuse, which is also based on a different tripping principle.
- the closed and triggered state described in connection with the transistor means the corresponding state of the transistor in which it essentially prevents or enables current flow.
- corresponding control circuits can be provided which are connected to the transistor in order to control the transistor for the desired triggering characteristic.
- a defined spatial distance of the at least two electrical contacts in the sense of the invention means a spatial distance which is determined by the spatial physical configuration of the contacts themselves and/or a receiving body in which the at least two electrical contacts can be accommodated.
- the defined distance is not a purely imaginary dimension between two components, but rather a structurally determined distance that cannot generally be changed.
- the grid spacing of a fuse or a relay refers to the structural spacing of the corresponding electrical components.
- the grid spacing of the fuse corresponds to a torpedo fuse, in particular according to DIN 72581-1:1993, or a flat plug fuse. It can be provided that the grid spacing is at least 9.1 mm, 10.9 mm, 19.1mm or 29.2mm.
- the designs and dimensions listed are particularly common, which has the advantage that a large number of fuses or relays can be replaced by appropriately designed replacement overcurrent protection.
- At least one further electrical contact is provided, with the at least one further electrical contact being arranged at the defined spatial distance from the at least two electrical contacts.
- a large number of electrical contacts are provided, although at least one of these contacts does not have to be suitable for providing a security functionality.
- an additional contact offers the advantage that the replacement overcurrent protection is more secure and, for example, unused fuse holders can be covered and thus protected.
- the further electrical contact is a power supply for the isolating circuit or that a signal can be transmitted via the further electrical contact. This has the advantage that the replacement overcurrent protection can provide additional functions.
- At least one further isolation circuit is provided, which is designed to enable current flow in a further circuit in a closed state and to interrupt a current flow in a further circuit in a triggered state.
- the isolation circuit can be designed to be able to open and close at least two circuits. This has the advantage that several fuses can be replaced with just one exchange of overcurrent protection. This can be particularly advantageous if the vehicle has a functional unit, e.g. B. a steer-by-wire steering is equipped or retrofitted, in which several fuses or relays are to be replaced by an exchange overcurrent protection according to the invention. The replacement overcurrent protection can then be installed “en bloc”, which simplifies production and increases safety as incorrect assembly is less likely.
- At least one diagnostic circuit is provided, which is designed to at least detect the state of at least the isolation circuit or to output it as a signal
- at least one channel function circuit is provided, which is designed to provide a channel function , which is specific to the operation of at least one consumer in the circuit.
- the replacement overcurrent protection can have corresponding electrical components which make it possible to at least monitor, forward or process the status of the isolation circuit and/or to provide further functions.
- the channel function circuit can provide pulse width modulation (PWM) for the circuit to which the isolation circuit is connected or a further circuit.
- PWM pulse width modulation
- the channel function circuit is designed to provide a circuit with which the Isolation circuit is connected, or can open another circuit if a predetermined condition, particularly defined in switching logic, is present. For example, a circuit relating to a lower-level system can be switched off, particularly as a precautionary measure, if the higher-level system has failed or has an error. This makes it possible to implement a safety concept at the overcurrent protection level, in particular with prioritization.
- the isolating circuit and the at least two electrical contacts are designed to have at least two, four, eight or twelve fuses or relays, in particular fuses with a fuse value of at least 20 A, 40 A or 80 A, to be functionally replaced.
- the isolation circuit can be designed to open and close a large number of circuits, including for different fuse values.
- the specified number of two, four, eight or twelve and the fuse values 20 A, 40 A or 80 A represent frequently occurring fuse requirements, so that replacement overcurrent protection designed in this way offers the advantage of being particularly versatile.
- a receiving body is provided, which is designed to accommodate at least the isolating circuit and the at least two electrical contacts, in particular the receiving body is dimensioned such that it essentially corresponds to the defined spatial distance, in particular the footprint corresponds to at least two electrical contacts.
- a carrier can be provided, which is designed to carry at least the isolating circuit and the at least two electrical contacts and to connect them to form a component.
- the receiving body is cast. As a result, the components contained in the receiving body are particularly well protected against environmental influences.
- the receiving body is designed as a heat sink and/or has a heat sink, which is in particular thermally connected to the isolation circuit. This makes it possible for even larger amounts of heat to be dissipated reliably, which can further increase the performance of the exchange overcurrent protection.
- the receiving body has a size that corresponds to a size of a housing of a, in particular standardized, preferably standardized fuse or a standardized, preferably standardized relay. This has the advantage that when installing at least one replacement overcurrent protector, collisions with one are avoided other replacement overcurrent protection, fuses, relays or other components that can be installed in a fuse box can be largely avoided.
- a fuse box for securing circuits in particular in a vehicle, comprising at least one replacement overcurrent protection according to the invention, in particular the replacement overcurrent protection being arranged on a slot for a fuse or a relay.
- the fuse box is constructed according to the grid dimension resulting from standardization, in particular standardization of the receptacles for the fuses. This offers the advantage that a fuse box designed in this way can be used in a particularly versatile manner.
- a vehicle having at least one replacement overcurrent protection according to the invention and/or a fuse box according to the invention.
- a vehicle according to the invention thus brings with it the same advantages as have already been described in detail with reference to an exchange overcurrent protection according to the invention and / or a fuse box according to the invention. Further advantages, features and details of the invention emerge from the following description, in which exemplary embodiments of the invention are described in detail with reference to the drawings. The features mentioned in the claims and in the description can be essential to the invention individually or in any combination. It shows schematically:
- Fig. 1 a representation of a fuse box with an overview of the recordings for
- Fuses and relays as well as an exemplary embodiment of replacement overcurrent protection in comparison with a conventional fuse
- Fig. 2 a representation of a defined spatial distance or one
- Figure 1 shows an exemplary embodiment of a replacement overcurrent protection 100 for securing a circuit for a fuse box 200, in particular in a vehicle 10.
- This has an isolating circuit with at least one transistor, wherein in a closed state current can flow via the transistor in the circuit and in a triggered state the circuit can be separated by the transistor, as well as at least two electrical contacts 110, which are arranged at a defined spatial distance 120 from one another, the circuit being able to be closed by an electrical connection of the at least two electrical contacts 110.
- the defined spatial distance 120 corresponds to a grid spacing 25 of a fuse 20 or a relay.
- the replacement overcurrent protection 100 can therefore be installed in a fuse box 200, in particular connected to a receptacle which is intended for a fuse 20 shown on the right or a relay.
- the contacts of the replacement overcurrent protection 100 have the same distance as that of a fuse 20 or a relay, as shown in the right part of FIG.
- the exchange overcurrent protection 100 according to the invention achieves the advantage that assembly with maximum flexibility can be carried out in an ongoing series.
- only the necessary outputs and not the entire vehicle 10 (shown in FIG. 3) need to be equipped.
- appropriate equipping with the replacement overcurrent protection 100 according to the invention can be carried out, depending on whether z.
- the steering system of a vehicle 10 is installed in the context of smaller or larger batteries.
- safety-relevant consumers can also be integrated into a product upgrade of the vehicle 10 without redeveloping the entire on-board network architecture.
- the fuse box 200 has at least one fuse section 230 or a relay section 220, which can in particular be spatially separated from one another.
- the spatial separation makes assembly easier, which makes the production of the fuse box 200 more cost-effective and safer.
- a receiving body 112 which is designed to accommodate at least the isolating circuit and the at least two electrical contacts 110, in particular the receiving body 112 being dimensioned such that it essentially corresponds to the defined spatial distance 120, in particular the Footprint 130 (shown in FIG. 2), which corresponds to at least two electrical contacts 110.
- the receiving body 112 has a size that corresponds to a size of a housing of a, in particular standardized, preferably standardized fuse 20 or a standardized, preferably standardized relay. This achieves the advantage that when installing at least one replacement overcurrent protection device 100, collisions with another replacement overcurrent protection device 100, fuses 20, relays or other components that can be installed in a fuse box 200 can be largely avoided.
- an exchange overcurrent protection 100 is shown schematically from below on the left, so that the at least two electrical contacts 110 in the defined spatial distance 120 as well as the further electrical contact 111 can be seen.
- the contacts 110, 111 of the replacement overcurrent protector 100 have a footprint 130, which corresponds to a pitch 210 corresponds (shown on the right), with the grid dimension 210 being formed by the distances between at least two fuses 20 and/or relays.
- the footprint 130 to the, in particular standardized, preferably standardized, grid dimension 210, the replacement overcurrent protection 100 can be used easily and can be used for a large number of fuse boxes 200.
- FIG. 3 shows a vehicle 10, which has an exemplary embodiment of a fuse box 200 and a replacement overcurrent protection 100.
- the vehicle can have several fuse boxes 200. These can in particular divide the circuits according to functional units and/or safety requirements. In other words, it can be provided that at least two fuse boxes 200 are provided, with the fuse boxes 200 differing at least in one function or a safety requirement of the protected circuits. This offers the advantage that the functional units (which may have increased security requirements) can be retrofitted more easily. For example, when replacing a functional group, the entire fuse box 200 can be replaced.
