Description

Technical Field

[0001] The present invention relates to the technical field of power distribution appliance connection devices, and in particular to a wiring device for a circuit breaker and the circuit breaker. Background Art

[0002] When the existing circuit breaker is connected to the power supply, copper busbar or busbar connection is generally used. When copper busbar connection is used, Fig.15 As shown, the copper bar has a first copper bar 01 that can be connected to the circuit breaker terminal, and a second copper bar 02 vertically connected to the first copper bar 01. The connection between the first copper bar 01 and the second copper bar 02 needs to be punched and connected by screws, which increases the temperature rise. In addition, since the creepage distance between copper bars of different phases needs to be considered, not only the amount of copper bar is increased, the cost is increased, but also the temperature rise is increased. When a busbar is used for connection, the same problems as above are also faced. In addition, since the busbar needs to be customized from the manufacturer, the cost is also high.

[0003] In order to solve the above technical problems, the Chinese patent document CN210325662U previously applied by the applicant discloses a power connection mechanism and a molded case circuit breaker, which includes a first mounting seat and a plurality of conductive components, the conductive components include a bracket, a clamping member rotatably mounted on the bracket, and a driving structure, the clamping member has a first rotating arm and a second rotating arm distributed on both sides of the rotating shaft, the driving structure is arranged on one side of the first rotating arm, and the second rotating arm is arranged opposite to the bracket to form a clamping groove for clamping the wiring copper busbar. When wiring, the flat wiring copper busbar is inserted into the clamping groove, and then the first rotating arm is driven to rotate by the driving structure to clamp the wiring copper busbar. Due to the long length of the conductive component, on the one hand, the length of the power connection mechanism is increased, which cannot meet the demand for miniaturization of the product, and on the other hand, the temperature rise of the product is increased.

[0020] The present invention also provides a circuit breaker, comprising a circuit breaker body and the wiring device for the circuit breaker as described above.

[0021] The technical solution of the present invention has the following advantages:

[0022] 1. The wiring device for the circuit breaker provided by the present invention comprises a wiring seat, a wiring busbar, a first conductive member, and a first fastening structure. The wiring busbar has a first busbar portion arranged vertically, and a plurality of first conductive members are arranged on the wiring seat at intervals along the width direction.

In addition, due to the small amount of copper material used, not only is the temperature rise of the product lower, the cost is also lower, and it also has the advantages of low energy consumption, which is more energy-saving.

[0023] 2. In the wiring device for a circuit breaker provided by the present invention, the first conductive member has a second connecting plate which is integrally bent and connected to the bottom of the first connecting plate and can be electrically connected to the control circuit inside the circuit breaker body.

In addition, since the plurality of second connecting plates are all located on the same horizontal plane, it is convenient to directly connect with the plurality of corresponding wiring terminals of the existing molded case circuit breaker, or to directly connect with the control circuit inside the circuit breaker body.

[0024] 3. In the wiring device for the circuit breaker provided by the present invention, the second conductive member is suitable for staggering the correspondingly arranged wiring busbars with the remaining non-corresponding first conductive members, thereby avoiding the wiring busbars between different phases from overlapping with the non-corresponding first conductive members to form a short circuit, and the safety and reliability are high.

[0028] 7. In the wiring device for the circuit breaker provided by the present invention, the wiring seat is provided with a mounting hole for installing the second conductive member, a first channel for installing the first connecting plate, and a mounting groove for installing the fixing plate in sequence along the first bolt insertion direction.

[0054] This embodiment provides a circuit breaker, such as Figure 1 , 2 As shown, it includes a circuit breaker body 8 and a wiring device arranged on one side of the circuit breaker body 8, wherein the wiring device for the circuit breaker includes a wiring seat 1, a wiring busbar 2, a first conductive member 3, a second conductive member 4, a first fastening structure 5 and a second fastening structure 7.

[0055] Terminal block 1, such as Figure 2 As shown, there are four busbar slots 11 evenly distributed in the height direction, and the wiring base 1 is provided with a mounting hole for mounting the second conductive member 4, a first channel for mounting the first connecting plate 31, and a mounting groove for mounting the fixing plate 6 from left to right, and a second channel 12 connecting the outside and the second connecting plate 32 is provided between the wiring base 1 and the circuit breaker body 8. In this embodiment, the wiring base 1 is integrally formed on the circuit breaker body 8.

[0056] There are four wiring busbars 2, which can be plugged into the corresponding busbar slots 11. The wiring busbar 2 has a first busbar portion 21 arranged vertically, and a second busbar portion 22 arranged perpendicular to the first busbar portion 21. The second busbar portion 22 is abutted against the mounting plate at the bottom of the busbar slot 11. The four first busbar portions 21 are all arranged on a first vertical plane. It should be noted that the same vertical plane indicates that the thickness of the four first busbar portions 21 is the same, and the positions of the left and right sides of each first busbar portion 21 are the same.

[0057] There are four first conductive members 3, which are evenly arranged on the terminal block 1 along the width direction. The first conductive member 3 is L-shaped, and has a first connecting plate 31 arranged vertically, and a second connecting plate 32 which is integrally bent and connected to the bottom of the first connecting plate 31 and can be electrically connected to the internal control circuit of the circuit breaker body 8. The four first connecting plates 31 are all arranged on a third vertical plane and are all arranged upward, and the four second connecting plates 32 extend in the same side direction and are all located on the same horizontal plane.

[0058] The second conductive member 4 has four parts, such as Figure 3-5 As shown, it is arranged between the corresponding first busbar portion 21 and the first connecting plate 31, and the second conductive member 4 is suitable for staggering the corresponding connection busbar 2 with the other non-corresponding first conductive members 3. In this embodiment, the four second conductive members 4 are arranged on the second vertical plane. Figure 3 and 4 As shown, taking the bottom-layer busbar as an example, since the four first connecting plates (31a, 31b, 31c, 31d) are all arranged on the third vertical plane, in order to prevent the first busbar portion 21a from overlapping with other first connecting plates (31b, 31c, 31d) while contacting with the first connecting plate 31a, a second conductive member 4 is provided so that a gap is provided between the overlapping of the busbar 2 and the other first connecting plates (31b, 31c, 31d) to avoid a short circuit.

[0059] like Figure 6 As shown, the first fastening structure 5 includes: a first through hole 51, which is provided on the first busbar part 21; a second through hole 52, which is provided on the second conductive member 4 and is arranged opposite to the first through hole 51; a third through hole 53, which is provided on the first connecting plate 31 and is arranged opposite to the second through hole 52; a first threaded hole 54, which is provided on the fixing plate 6 and is arranged opposite to the third through hole 53; a first bolt, which passes through the first through hole 51, the second through hole 52, the third through hole 53, and the first threaded hole 54 in sequence, fixes and connects the first busbar part 21, the second conductive member 4, the first connecting plate 31, and the fixing plate 6. It should be noted that the threaded hole can also be directly processed on the first connecting plate 31, thereby eliminating the fixing plate 6.

[0060] The second conductive member 4, the first connecting plate 31, and the fixing plate 6 are fixedly connected by a second fastening structure 7. Figure 6As shown, the second fastening structure 7 includes: a fourth through hole 71, which is provided on the second conductive member 4; a fifth through hole 72, which is provided on the first connecting plate 31 and is arranged opposite to the fourth through hole 71; a second threaded hole 73, which is provided on the fixing plate 6 and is arranged opposite to the fifth through hole 72; and a second bolt, which passes through the fourth through hole 71 and the fifth through hole 72 in sequence, and is threadedly connected with the second threaded hole 73. During assembly, the fixing plate 6 is first installed in the installation groove, and then the first connecting plate 31 of the first conductive member 3 is inserted into the first channel, and finally the second conductive member 4 is inserted into the installation hole, and the second conductive member 4, the first connecting plate 31 and the fixing plate 6 are fixedly connected by the second fastening structure.

[0061] As a convertible implementation method, Fig.11 As shown, the four first connecting plates 31 are all arranged downward.

[0062] As a convertible implementation method, Fig.12 and 13 As shown, two of the four first connecting plates 31 are arranged downward, and the other two are arranged upward, so that the total height of the four first busbar parts can be reduced, so that the amount of copper consumables is also small, which on the one hand reduces the production cost, and on the other hand is more energy-saving and has the advantage of low energy consumption.

[0063] As a convertible implementation method, Figure 7 As shown, the four first connecting plates 31 are all arranged on the third vertical plane, and the lengths of the four second conductive members 4 gradually increase from top to bottom.

[0064] As a convertible implementation method, Figure 8 and 9 As shown, a plurality of busbars 2 are arranged in a stepped manner, and each layer is composed of only busbars 2 , first conductive members 3 and fixing plates 6 .

[0065] As a convertible implementation method, Fig.10 As shown, the second conductive member 4 can be integrally formed on the first busbar portion 21 or the first connecting plate 31, that is, the second conductive member 4 can be welded or riveted to the first busbar portion 21; the second conductive member 4 and the first conductive member 3 can be directly stamped from the same plate, or the second conductive member 4 can be integrally bent and connected to the first conductive member 3.

[0066] As an alternative embodiment, the first fastening structure and the second fastening structure may be connected by rivets or welding.

[0067] As a convertible implementation, the terminal block 1 and the circuit breaker body 8 are separately provided.

[0068] As an alternative implementation, the wiring device can be connected to 2, 3, 4 or more circuit breakers at the same time.

[0069] It should be noted that the wiring device of the present invention can also be used for distribution appliances such as contactors and fuses.

[0070] The wiring device for a circuit breaker provided by the present invention comprises a wiring seat 1, a wiring busbar 2, a first conductive member 3, and a first fastening structure 5. The wiring busbar 2 has a first busbar portion 21 arranged vertically, and a plurality of first conductive members 3 are arranged on the wiring seat 1 at intervals along the width direction. The first conductive member 3 has a first connecting plate 31 arranged vertically. Since the plurality of first connecting plates 31 are arranged vertically in a staggered manner along the width direction, the plurality of first busbar portions 21 arranged along the height direction can be directly connected to the corresponding first connecting plates 31, and the structure is simpler; and the first busbar portions 21 and the first connecting plates 31 of each layer are arranged vertically, which greatly reduces the length of the wiring device for the circuit breaker. Compared with the prior art method of fixing the busbar using a bracket, a clamping member, and a driving structure, the product is more miniaturized. In addition, due to the small amount of copper material used, not only is the temperature rise of the product lower, but the cost is also lower.

[0071] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
