Abstract
Description
[Technical field]
[0001] The present invention relates to a distributor block and a method for producing a distributor block. [Background technology]
[0002] A distributor block serves to supply current or power to a number of outputs via a common supply input. The total total current of all outputs is provided via the supply input. In this case, it may occur that the supply input is overloaded if a total current greater than the size of the supply input provides is output via the outputs. Furthermore, fluctuations in the total current, especially short-term overloads, may cause damage to upstream or downstream electrical components. Summary of the Invention [Problem to be solved by the invention]
[0003] The invention is therefore based on the task of specifying a distributor block which allows a reliable and safe operation. Furthermore, a method for producing such a distributor block is defined. [Means for solving the problem]
[0004] This problem is solved according to the invention by means of the features of the independent claims. Exemplary embodiments and advantageous developments of the invention are defined in the dependent claims.
[0005] According to the present invention, a distributor block is defined having a supply input and a number of outputs, the supply input having an input terminal for connecting with an electrical conductor and each of the outputs having an output terminal for connecting with an electrical conductor, the supply input being electrically conductively connected with a first current bar and each of the outputs being electrically conductively connected with a second current bar, fuses and / or switches are disposed between the first and second current bars to connect the first and second current bars, and receptacles for holding the fuses and / or switches are provided between the first and second current bars.
[0006] By incorporating a fuse, the distributor block provides protection against overloads. Alternatively or additionally, with the aid of a switch, the distributor block allows disconnecting and connecting the first current bar to the second current bar.
[0007] The switch may for example be a circuit breaker or a residual current circuit breaker (RCD).
[0008] The fuse or fuses may be disposed in one or more receptacles between the first and second current bars.
[0009] Alternatively or additionally, the switch or switches may be disposed in one or more receptacles between the first and second current bars.
[0010] It may be proposed that the supply input and the first current bar are configured for transmitting a nominal current of greater than 10 amperes and less than 50 amperes, at a nominal voltage of, for example, 450 volts.
[0011] It may be provided that the supply input and the first current bar are configured to carry a maximum total current of greater than 30 amps and less than 100 amps.
[0012] It may be provided that the splitter block may be operated at a nominal voltage of 800 volts. In particular, the splitter block may be operated at a nominal voltage selected from the range of 100 volts to 1000 volts.
[0013] The receptacle may be riveted to the first current bar. Alternatively or additionally, the receptacle may be riveted to the second current bar. Thus, the first and / or second current bars may be used with and connected to different receptacles, and the distributor block may be provided with receptacles for holding specific fuses and / or specific switches in an application-specific manner. For the design and manufacture of various derivatives of the distributor block, this provides the advantage that the same design of the current bar may be used with different receptacles and does not have to be redesigned for each receptacle.
[0014] In the present case, when "different" receptacles are mentioned, these are receptacles that differ in shape and / or size.
[0015] Alternatively or additionally, it may be provided that the receptacle is welded to the first current bar and / or that the receptacle is welded to the second current bar, thus creating a secure bonded connection to ensure electrical contact between the components welded together.
[0016] It may be provided that a receptacle is screwed onto the first current bar and / or that a receptacle is screwed onto the second current bar, thus allowing a removable connection.
[0017] It may be provided that the receptacle is hooked to a first current bar and / or that the receptacle is hooked to a second current bar, thus enabling a detachable connection, in particular a pressure-fit and / or form-fit connection.
[0018] The receptacle may have a first terminal lug configured to connect the receptacle with a first current bar, in particular by means of a riveting connection and / or welding, for example.
[0019] The receptacle may have a second terminal lug configured to connect the receptacle with a second current bar, in particular by means of a riveting connection and / or welding, for example.
[0020] The receptacle may be configured to hold a vehicle fuse. For example, it may be a type C vehicle fuse (e.g., according to ISO 8820-3; 2015-09). The receptacle may have a separation zone that is bridged by the contacts of the fuse to connect the first and second current bars to each other in an electrically conductive manner.
[0021] Alternatively, the receptacle may be configured to hold a G fuse (e.g., according to DIN EN60127-1 VDE0820-1:2015-12). The receptacle may have a socket for receiving the fuse to connect the first current bar and the second current bar to each other in an electrically conductive manner.
[0022] Alternatively, the receptacle may be configured to hold a switch, which may be, for example, a residual current interrupter, to connect the first and second current bars to one another in an electrically conductive manner in a first switch position, and to disconnect them from one another in a second switch position.
[0023] It may be provided that the first current bar has a larger conductor cross-sectional area and / or a larger wall thickness than the second current bar, and is thus designed or dimensioned to reliably transmit the total current that is output via the output.
[0024] For example, it may be provided that the first current bar has a wall thickness of 1 mm or more, or a maximum wall thickness of 2 mm, in particular a wall thickness of 1.1 mm, or that the second current bar has a wall thickness of less than 1 mm, in particular a wall thickness of 0.8 mm.
[0025] The first current bar may be a sheet metal component produced from sheet metal by forming and / or stamping.
[0026] The second current bar may be a sheet metal component produced from sheet metal by forming and / or stamping.
[0027] In the present case, when wall thickness is mentioned, this may in particular be the sheet metal thickness of the metal sheet in each case for producing the first and second current bars. It is understood that the first and second current bars may be produced from different metal sheets which may have different sheet metal thicknesses. Thus, the first metal sheet from which the first current bar is produced has a greater wall thickness than the second metal sheet from which the second current bar is produced.
[0028] The first current bar and / or the second current bar may comprise or consist of a metallic material.
[0029] The distributor block may in particular be designed according to IEC 60947-7-7 and / or IEC 60998-2-2.
[0030] A distributor block may for example have exactly one feed input.
[0031] The distributor block may have more than four outputs, in particular more than ten outputs, in particular up to twelve outputs.
[0032] It may be provided that the supply input and / or the output are designed as a push-in connection, which allows a tool-free attachment of the cable ends to the supply input and / or output.
[0033] The output is 0.14 mm 2 ~4mm 2 In particular, the conductor cross-sectional area is selected from the range of 0.34 mm 2 ~2.5mm 2 The supply input may be configured to accept a conductor cross-sectional area selected from the range of up to 16 mm 2 The conductor cross-sectional area may be provided to accommodate up to 100 conductor cross-sectional areas.
[0034] The outputs may be arranged in two rows and / or with mirror symmetry.
[0035] The supply input can be arranged offset with respect to the output, the offset making it possible to mount larger conductor cross-sections in a simple manner.
[0036] The supply input and the output may have openings for inserting the conductors, which are arranged on one side of the housing of the distributor block, and thus the supply input and the output may in particular be accessible from one and the same side of the distributor block.
[0037] The present invention further relates to a method for producing a distributor block, the method comprising the following method steps: producing a first distributor block according to the invention; and producing a second distributor block according to the invention, in which the receptacles for holding fuses and / or switches of the first distributor block and the receptacles for holding fuses and / or switches of the second distributor block are not structurally identical, the first current bars of the first distributor block and the first current bars of the second distributor block are structurally identical, and / or the second current bars of the first distributor block and the second current bars of the second distributor block are structurally identical.
[0038] For this reason, two distributor blocks can be manufactured with different receptacles while structurally identical current bars can still be used.
[0039] In particular, it can be provided that in a further method step a third distributor block is produced which does not have fuses and / or switches or receptacles for holding fuses and / or switches, the first current bar of the third distributor block being structurally identical to the first current bar of the first and second distributor blocks and / or the second current bar of the third distributor block being structurally identical to the second current bar of the first and second distributor blocks. Thus, structurally identical current bars can also be used for protection of the distributor block which does not have fuses and / or switches.
[0040] The first and second current bars of the third distributor block may be riveted together. The first and second current bars of the third distributor block may be welded together. The first and second current bars of the third distributor block may be screwed together. The first and second current bars of the third distributor block may be latched together.
[0041] According to the invention, a modular system for producing distributor blocks can be defined, where structurally identical first current bars can be connected with different, structurally non-identical receptacles of a distributor block to produce different distributor blocks according to the invention depending on the application. It can further be provided that structurally identical second current bars can be connected with different, structurally non-identical receptacles of a distributor block to produce different distributor blocks according to the invention depending on the application. It can further be provided that the first current bars are connected with the second current bars to provide a distributor block without fuses and / or switches.
[0042] In particular, it can be provided that the first current bar of the first distributor block according to the invention of the modular system comprises openings and / or recesses which are positioned above, substantially in line with and / or at least partially engaged with, the openings and / or recesses of the first receptacle in the housing of the distributor block in the pre-assembled state in order to predetermine the position of the rivet connection or multiple rivet connections.
[0043] In particular, it can be provided that the second current bar of the first distributor block according to the invention of the modular system comprises openings and / or recesses which are positioned above and substantially coincident with each other and / or at least partially engage with each other in the housing of the distributor block in the pre-assembled state with respect to the openings and / or recesses of the first receptacle in order to predetermine the position of the rivet connection or multiple rivet connections.
[0044] In particular, it may be provided that the first current bar of the second distributor block according to the invention of the modular system comprises openings and / or recesses which are located substantially above and / or at least partially engage with each other with openings and / or recesses of a second receptacle different from the first receptacle in the housing of the distributor block in the pre-assembled state in order to predetermine the position of the rivet connection or connections. The first current bar of the first distributor block and the first current bar of the second distributor block are structurally identical.
[0045] It may further be provided that the second current bar of the second distributor block of the modular system has openings and / or recesses which are located substantially above and / or at least partially engage with each other with openings and / or recesses of a second receptacle different from the first receptacle in the housing of the distributor block in a pre-assembled state in order to predetermine the position of the rivet connection or connections. The second current bar of the first distributor block and the second current bar of the second distributor block are structurally identical.

[Figure 5B] FIG. 5B is a schematic view of the distributor block according to FIG. 5A from below. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0049] FIG. 1A shows a distributor block 100 having a feed input 110 and multiple outputs 120 .
[0050] The supply inputs 110 have an input terminal 111 for connection with an electrical conductor. The outputs 120 each have an output terminal 121 for connection with an electrical conductor.
[0051] An opening 112 in the supply input 110 for introducing a conductor end of an electric conductor is assigned to an input terminal 111. The input terminal 111 extends into a housing 130 of the distributor block 100 and grips the conductor end inside the housing 130 in the area of the opening 112 in order to fix the conductor to the distributor block 100. For this reason, only a part of the input terminal 111 is visible, which can be actuated by a tool such as a screwdriver to release the fixed conductor, this being the actuating element, also called pusher. Here, the supply input 110 or the input terminal 111 is designed as a push-in connection.
[0052] An opening 122 of each output part 120 for inserting a conductor end of an electric conductor is assigned to each output terminal 121. The output terminal 121 extends into a housing 130 of the distributor block 100 and grips the conductor end inside the housing 130 in the region of the opening 122 in order to fix the conductor to the distributor block 100. For this reason, only a part of the respective output terminal 121 is visible, which can be actuated to release the fixed conductor by a tool such as a screwdriver. Each output part 120 or output terminal 121 is designed as a push-in connection.
[0053] The supply input 110 is electrically conductively connected to a first current bar 140 .
[0054] Each output 120 is electrically conductively connected to a second current bar 150 .
[0055] A receptacle 160 for holding a fuse is disposed between the first current bar 140 and the second current bar 150. In the present case, the receptacle 160 is provided to hold a type C vehicle fuse.
[0056] The receptacle 160 forms an isolation zone or gap 161 such that, unless a fuse is placed in the receptacle 160, the current bars 140, 150 are isolated from each other by the isolation zone 161 or gap 161, as shown in FIG. 1B.
[0057] When the fuse is inserted into the receptacle 160, the fuse and its contacts establish an electrically conductive connection between the first current bar 140 and the second current bar 150. To this end, a first contact portion of the fuse abuts a first terminal lug 170 of the receptacle 160 and a second contact portion of the fuse abuts a second terminal lug 180 of the receptacle 160.
[0058] Two rivet connections 171 are formed between the terminal lug 170 and the first current bar 140 .
[0059] Two rivet connections 181 are formed between the terminal lug 180 and the second current bar 150 .
[0060] In this case, the first current bar 140 has a larger conductor cross-sectional area and a larger wall thickness than the second current bar 150 .
[0061] The first current bar 140 has a wall thickness of 1.1 mm. The second current bar 150 has a wall thickness of 1 mm or less.
[0062] The distributor block 100 has exactly one feed input 110 and exactly twelve outputs 120 .
[0063] The output sections 120 are arranged in two rows and in mirror symmetry.
[0064] The supply input section 110 is positioned offset relative to the output section 120 .
[0065] The supply input 110 and output 120 are arranged such that their openings 112 , 122 and terminals 111 , 121 are on a common side 131 of a housing 130 of the distributor block 100 .
[0066] Side 131, which may also be referred to as upper side 131, faces away from lower side 132 of housing 130 on which sections of current bars 140, 150 are located.
[0067] The housing 130 comprises an electrically insulating plastic, in this case polyamide.
[0068] 2A and 2B show a further variation of a distributor block 200. To avoid repetition, only the differences from the above-described exemplary embodiment will be discussed and like features will be assigned like reference numbers.
[0069] The distributor block 200 differs from the above-described exemplary embodiment in that it is provided with a receptacle 260 for holding a G fuse 300. Thus, the fuse 300 is disposed between the first current bar 140 and the second current bar 150 to electrically conductively connect the first current bar 140 and the second current bar 150 to each other.
[0070] The receptacle 260 has a first socket 261 for holding the fuse 300. The receptacle 260 has a second socket 262 for holding the fuse 300.
[0071] The first socket 261 is electrically conductively connected to the terminal lug 170 of the receptacle 260. The second holder 262 is electrically conductively connected to the terminal lug 180 of the receptacle 260.
[0072] The first holder 261 is integrally formed with the terminal lug 170 .
[0073] Thus, for distributor block 100 and distributor block 200, a structurally identical first current bar 140 and a structurally identical second current bar 150 can be used, which are connected to terminal lugs 170, 180 via rivet connections 171, 181. Thus, the current bars 140, 150 are only connected to different receptacles 160, 260 in order to use different fuses in the distributor blocks 100, 200.
[0074] 3 shows a further variation of the distributor block 400. To avoid repetition, only the differences from the above-described exemplary embodiment will be discussed and similar features will be assigned similar reference numbers.
[0075] The distributor block 400 differs from the above-described exemplary embodiment in that a receptacle 460 is provided between the current bars and configured to hold a switch 500 .
[0076] The switch 500 is used to make and break the electrically conductive connection between the current bars 140,150.
[0077] Also, a first current bar 140 structurally identical to that of the distributor blocks 100, 200 is used for the distributor block 400. Moreover, a second current bar 150 structurally identical to that of the distributor blocks 100, 200 is used for the distributor block 400.
[0078] In this case, switch 500 is a residual current interrupter.
[0079] According to FIG. 4, a method for producing a distributor block is described, the method comprising the following method steps: A) producing a first distributor block, the distributor block being the distributor block 100 shown in FIG. 1A; B) producing a second distributor block, the distributor block being the distributor block 200 shown in FIG. 2A; The receptacle 160 for holding the fuse of the distributor block 100 and the receptacle 260 for holding the fuse 300 of the distributor block 200 are not structurally identical; the first current bar 140 of the distributor block 100 and the first current bar 140 of the distributor block 200 are structurally identical, and the second current bar 150 of the distributor block 100 and the second current bar 150 of the distributor block 200 are structurally identical; C) producing a third distributor block, the distributor block being the distributor block 400 shown in FIG. 3 or the distributor block 600 shown in FIG. 5A; Includes.
[0080] The distributor block 600 shown in Fig. 5A has neither fuses nor switches. Here, the first current bar 140 and the second current bar 150 are directly riveted to each other, as shown by the rivet connection 151 in Fig. 5B. Also, the first current bar 140 structurally identical to that of the distributor blocks 100, 200, 400 is used for the distributor block 600. Moreover, the second current bar 150 structurally identical to that of the distributor blocks 100, 200, 400 is used for the distributor block 600.
[0081] Thus, a modular system for producing distributor blocks 100, 200, 400, 600 can be defined, in which structurally identical first current bars 140 can be connected with different, structurally non-identical receptacles 160, 260, 460 of the distributor blocks 100, 200, 400 to produce different distributor blocks 100, 200, 400 according to the invention, depending on the application.
[0082] Furthermore, it can be proposed that the structurally identical second current bars 150 can be connected with different, structurally non-identical receptacles 160, 260, 460 of the distributor blocks 100, 200, 400 to produce different distributor blocks 100, 200, 400 according to the invention, depending on the application.
[0083] Furthermore, it can be proposed that the first current bar 140 is connected with the second current bar 150 to provide a distributor block 600 without fuses and / or switches 500 . [Explanation of symbols]
