Technical Field

[0001] This invention relates to the field of electrical connection technology, and more specifically to a busbar adapter. Background Technology

[0002] Busbar adapters are typically used to connect circuit breakers to busbar systems. However, in practice, there are many types of circuit breakers, and different types often have different fixed spacings. Conventional busbar adapters cannot be installed on different types of circuit breakers, resulting in poor compatibility. Summary of the Invention

[0005] With this configuration, the first nut can slide relative to the first nut in the first direction through the sliding sleeve, and can also slide relative to the first nut in the second direction within the sliding sleeve. This allows the first nut to be adjusted in both the first and second directions, resulting in a wider adjustment range and better adaptability to the installation of different types of circuit breakers, thus improving compatibility. At the same time, it can also reduce the types of busbar adapters, thereby facilitating the management and use of busbar adapters.

[0017] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] The terms "first" and "second" used in this article are used only for the convenience of describing two or more structures or components that are identical or similar in structure and / or function, and do not indicate any special limitation on order and / or importance.

[0019] Please refer to Figures 1-6 , Figure 1 This is a specific embodiment of the busbar adapter provided by the present invention and a connection structure diagram of the busbar system. Figure 2 This is a connection structure diagram of the sliding sleeve, the seat body, and the first nut component. Figure 3 This is a diagram showing the connection structure between the sliding sleeve and the first nut. Figure 4 for Figure 3 A structural diagram from another perspective. Figure 5 This is a diagram showing the connection structure between the circuit breaker and its base. Figure 6 This is a diagram showing the installation structure of the busbar and the base.

[0020] As described in the background section, the busbar adapter is mainly used to realize the electrical connection between the circuit breaker 7 and the busbar system 8. Generally, the circuit breaker 7 and the busbar adapter are connected by a first threaded connector 71. In specific implementation, the first threaded connector 71 can be a screw or bolt, etc. The busbar adapter can have a threaded hole, and the circuit breaker 7 can have a through hole. The first threaded connector 71 can pass through the through hole of the circuit breaker 7 and be threadedly connected to the threaded hole of the busbar adapter, thereby fixing the circuit breaker 7 to the busbar adapter.

[0021] However, the threaded hole positions of conventional busbar adapters are fixed, which means that the busbar adapter can only be installed with one type of circuit breaker 7, resulting in poor compatibility. When the type of circuit breaker 7 changes, a new busbar adapter needs to be redesigned, which also leads to a large variety of busbar adapters, making management difficult.

[0022] Therefore, embodiments of the present invention provide a busbar adapter, such as... Figure 1 , Figure 2 As shown, the busbar adapter includes a base 1, on which a conductive bar 2 and a first nut 3 are mounted. The first nut 3 is slidably connected to the base 1 and is used to adjust the mounting position of the first nut 3 on the base 1. The first nut 3 is provided with a threaded hole 31.

[0023] With this structure, the first nut 3 of the busbar adapter provided by the present invention can be adjusted in the mounting position of the base 1, which can adapt to the installation of different types of circuit breakers 7 to improve compatibility. At the same time, it can also reduce the types of busbar adapters, thereby facilitating the management and use of the busbar adapters.

[0024] It should be noted that the first nut 3 mentioned above is only one specific form of threaded engagement component in the bus adapter provided in the embodiment of the present invention, which is used to cooperate with the first threaded connector 71. The installation position of this threaded engagement component can be adjusted to achieve the technical purpose of adapting to the installation of different types of circuit breakers 7. However, the bus adapter provided in the embodiment of the present invention does not necessarily only have threaded engagement components with adjustable installation positions. There may also be threaded engagement components with fixed installation positions. For example, the threaded engagement component with a fixed installation position may be a threaded hole provided in the base 1. That is to say, only a part of the threaded engagement components may have adjustable installation positions, which is also a technical solution that can be adopted in specific practices.

[0025] The specific form of the sliding fit structure between the first nut 3 and the base 1 can vary. In practice, those skilled in the art can choose according to actual needs, as long as the corresponding technical effect can be achieved. Similarly, the sliding direction of the first nut 3 on the base 1 is not limited.

[0026] In a specific scheme, such as Figures 2-4 As shown, the base 1 may include a seat body 11 and a sliding sleeve 12. The seat body 11 may be provided with a first slide rail 111 extending along a first direction. The sliding sleeve 12 may be slidably connected to the first slide rail 111. The first nut 3 may be installed in the sliding sleeve 12 and may slide within the sliding sleeve 12 along a second direction. The first direction and the second direction may be set at an angle.

[0027] Thus, the first nut 3 can slide relative to the sliding sleeve 12 in the first direction, and can also slide relative to the sliding sleeve 12 in the second direction, allowing the first nut 3 to be adjusted in both the first and second directions, resulting in a wider adjustable range. Therefore, the bus adapter provided in this embodiment can accommodate the installation of bus adapters with different fixed spacings in the first direction and / or different fixed spacings in the second direction.

[0028] Here, the fixed spacing in the first direction refers to the spacing between the two first threaded connectors 71 in the first direction, and the fixed spacing in the second direction refers to the spacing between the two first threaded connectors 71 in the second direction. The specific value of the included angle between the first direction and the second direction is not limited here. In practice, those skilled in the art can set it according to actual needs. Generally speaking, the included angle between the first direction and the second direction can be 90 degrees.

[0029] Please continue to refer to this. Figure 3 and Figure 4 The sliding sleeve 12 may include a top plate 123 and a peripheral plate. The peripheral plate may include two first plates 121 arranged opposite each other in a first direction and two second plates 122 arranged opposite each other in a second direction. Both first plates 121 and two second plates 122 are connected to the peripheral plate. The second plates 122 can be slidably connected to the first slide rail 111. The specific form of the sliding fit structure between the second plates 122 and the first slide rail 111 is not limited here. Figure 3 In this embodiment, the second plate 122 can be bent to form a groove structure, which can then form a sliding fit with the first slide rail 111 of the seat 11. The sliding fit between the second plate 122 and the first slide rail 111 can have a certain interference in the second direction, so that the sliding sleeve 12 can be locked in the first slide rail 111 to ensure the installation position of the sliding sleeve 12 without external force. The first nut 3 can be clearance-fitted with the second plate 122 in the second direction, so that the first nut 3 can slide between the two second plates 122 in the second direction.

[0030] The sliding sleeve 12 may also be provided with a limiting member, which, along with the top plate 123, can be used to limit the position of the first nut 3 in the third direction, so as to prevent the first nut 3 from coming out of the sliding sleeve 12 in the third direction. The third direction may be perpendicular to both the first and second directions.

[0031] Here, the embodiments of the present invention do not limit the specific structural form of the limiting member. In practical applications, those skilled in the art can make settings as needed, as long as the above-mentioned technical effects can be achieved. In an exemplary solution, at least one of the first plate 121 and the second plate 122 may be provided with an edge portion 121a, which can serve as the aforementioned limiting member; Figure 4 In the embodiment, the edge portion 121a may be formed solely from the first plate 121.

[0032] Please continue to refer to this. Figure 3 , Figure 4 The first nut 3 is actually installed in the cavity formed by the two first plates 121, the two second plates 122, the top plate 123, and the edge portion 121a. The two first plates 121 can limit the first nut 3 in a first direction, the two second plates 122 can limit the first nut 3 in a second direction, and the top plate 123 and the edge portion 121a can limit the first nut 3 in a third direction.

[0033] The end of the first nut 3 facing the top plate 123 can be used as the insertion end. In this case, a hollow structure 123a needs to be provided in the top plate 123 to expose the threaded hole 31, so that the first threaded connector 71 can be inserted into the threaded hole 31 from the top plate 123. Alternatively, the end of the first nut 3 away from the top plate 123 can also be used as the insertion end. In this case, the binding range of the binding portion 121a needs to be controlled to avoid the binding portion 121a from obscuring the threaded hole 31, so that the first threaded connector 71 can be inserted into the threaded hole 31 from the binding portion 121a.

[0034] Furthermore, the first nut part 3 may also be provided with a tapered guide hole 32, which can be connected to the threaded hole 31. The diameter of the guide hole 32 can gradually decrease along the direction close to the threaded hole 31.

[0035] During specific assembly, the first threaded connector 71 can first contact the guide hole 32 and be guided by the hole wall of the guide hole 32, so that the first threaded connector 71 can be inserted into the threaded hole 31 more easily; moreover, the process of the hole wall of the guide hole 32 guiding the first threaded connector 71 is actually the process of the first threaded connector 71 adjusting the installation position of the first nut 3.

[0036] Furthermore, the first nut component 3 may be provided with multiple threaded holes 31, and the diameter of each threaded hole 31 may be different. That is to say, the first nut component 3 may also be configured with threaded holes 31 of various specifications to adapt to combination and assembly with first threaded connectors 71 of different specifications.

[0037] Here, the embodiments of the present invention do not limit the number of threaded holes 31 provided in a first nut 3. In practice, those skilled in the art can set the number according to actual needs. Generally speaking, the number of threaded holes 31 can be set to two, and the specifications of the two threaded holes 31 can be M6 and M5 respectively.

[0038] In addition to different fixed spacings and different first threaded connectors 71, different models of circuit breakers 7 may also have different phase-to-phase distances. Therefore, the busbar adapter provided in this embodiment of the invention can also be equipped with corresponding improved structures to accommodate the assembly of circuit breakers 7 with different phase-to-phase distances, thereby further improving the compatibility of the busbar adapter.

[0039] Please refer to Figures 7-11 , Figure 7 This is a schematic diagram of the conductor bus structure. Figure 8 for Figure 7 A magnified view of part A in the middle. Figure 9 This is a schematic diagram of the second nut component. Figure 10 This is a structural diagram of the circuit breaker and its base before installation. Figure 11 This is a schematic diagram of another specific embodiment of the busbar adapter provided by the present invention.

[0040] The conductive busbar 2 is typically made of copper, but other conductive materials such as aluminum, iron, or other metals, or some non-metallic conductive materials, can also be used. There can be multiple conductive busbars 2, and they can be spaced apart on the base 1. This spacing is actually in the aforementioned second direction. Here, this embodiment of the invention does not limit the number of conductive busbars 2; it depends on the model of the circuit breaker 7. If the circuit breaker 7 is a three-pole circuit breaker, then the number of conductive busbars 2 can be three. This implementation can be found in [reference needed]. Figure 7 and Figure 10 If circuit breaker 7 is a four-pole circuit breaker, then the number of conductor bars 2 can be four. This implementation method can be found in [reference needed]. Figure 11 .

[0041] At least one conductive bar 2 may be configured with a strip hole 21 extending in the aforementioned spaced direction; it may also include a second nut 4, which may be opposite to the strip hole 21 and be slidable in the spaced direction for connection with a second threaded connector 72 that fixes the conductive post 73.

[0042] The second threaded connector 72 can slide along the spaced direction, which can accommodate the assembly of circuit breakers 7 with different phase-to-phase distances, and further improve the compatibility of the bus adapter provided in the embodiment of the present invention.

[0043] Taking a scheme with three conductive busbars 2 as an example, each of the three conductive busbars 2 can be provided with the aforementioned strip hole 21 and a second nut 4 corresponding to the corresponding strip hole 21. In this case, the connection position between each conductive busbar 2 and the second threaded connector 72 can be adjusted. Alternatively, one of the three conductive busbars 2 can have a threaded connection hole with a fixed position, which can be used as a reference during installation, while the other two conductive busbars 2 are provided with the aforementioned strip hole 21 and the second nut 4. This can also meet the usage requirements.

[0044] The second nut 4 can be slidably connected to the base 1, or to the conductive busbar 2, or to both the base 1 and the conductive busbar 2. In specific implementation, those skilled in the art can choose according to actual needs.

[0045] In the embodiments shown in the accompanying drawings, such as Figure 8 As shown, the second nut 4 can be slidably connected to the conductive busbar 2, specifically slidably connected to the wall of the strip hole 21, and the second nut 4 can be snapped into the wall of the strip hole 21 to prevent the second nut 4 from disengaging from the conductive busbar 2 in the third direction.

[0046] In detail, combined Figure 9 The peripheral wall of the second nut 4 may be provided with a flattened portion 41 to increase the sliding contact area between the second nut 4 and the strip hole 21, thereby improving the stability of the sliding connection between the second nut 4 and the strip hole 21. In the flattened portion 41 and the hole wall of the strip hole 21, one may be provided with a snap-fit ​​protrusion (not shown in the figure) and the other may be provided with a snap-fit ​​groove (not shown in the figure). The snap-fit ​​protrusion can be snapped into the snap-fit ​​groove to realize the snap-fit ​​assembly of the second nut 4 and the conductive busbar 2. At the same time, the cooperation between the snap-fit ​​protrusion and the snap-fit ​​groove can also guide the sliding of the second nut 4 in the conductive busbar 2.

[0047] Combination Figure 10 During the specific assembly, the second threaded connector 72 can be inserted into the circuit breaker 7 first. Then, the conductive post 73 (which can be a copper post, or of course, other conductive materials) can be sleeved and installed on the second threaded connector 72 and overlapped with the circuit breaker 7. Then, the second threaded connector 72 can be mated with the second nut 4 and tightened. During the tightening process, the second threaded connector 72 can also adjust the position of the corresponding second nut 4 to adapt to the phase-to-phase distance of the circuit breaker 7.

[0048] Please refer to Figure 12 , Figure 12 This is a schematic diagram of another specific embodiment of the busbar adapter provided by the present invention.

[0049] Unlike the above-mentioned solution of setting a strip hole 21 and a second nut 4 on the conductor busbar 2, this embodiment of the invention also provides another solution that can adapt to the installation of circuit breakers 7 with different phase-to-phase distances.

[0050] Specifically, such as Figure 12 As shown, it may also include a flexible conductive plate 5. One end of the flexible conductive plate 5 can be connected to the conductive busbar 2, and the other end can be connected to the circuit breaker 7. Since the flexible conductive plate 5 has flexible deformation capability, it can adapt well to the installation of circuit breakers 7 with different phase-to-phase distances, thereby ensuring the compatibility of the busbar adapter.

[0051] Here, the material of the flexible conductive plate 5 is not limited in this embodiment of the invention. In practice, those skilled in the art can choose according to actual needs.

[0052] Please refer to Figures 13-14 , Figure 13 This is a structural diagram of the extended seat. Figure 14 This is a diagram showing the connection structure between the base and the extension seat.

[0053] In practical applications, there are also circuit breakers 7 that integrate leakage current detection modules or automatic reclosing functions. These circuit breakers 7 have a longer length (dimension in the first direction), which leads to a significant increase in the fixed spacing. Conventional busbar adapters cannot meet the requirements for fixed installation.

[0054] Therefore, the busbar adapter provided in this embodiment of the invention may further include an extension seat 6, which may be connected to the base 1 to extend the length of the entire busbar adapter. The extension seat 6 may also be provided with a second slide rail 64 corresponding to the first slide rail 111. The second slide rail 64 may also extend along the first direction and be connected to the first slide rail 111. In this way, the aforementioned sliding sleeve 12 may also be slidably connected to the second slide rail 64, so that the first nut 3 may also slide into the extension seat 6, thereby adapting to the installation of a longer circuit breaker 7.

[0055] The method of fixing the extension base 6 and the base 1 is not limited here, as long as a reliable connection between the two can be guaranteed. For example, the extension base 6 and the base 1 can be connected by threaded fasteners such as screws or bolts; or, the extension base 6 and the base 1 can also be fixed by various methods such as riveting, welding, bonding, or snap-fitting.

[0056] Taking a snap-fit ​​connection as an example, the extension base 6 can be provided with a mating block 61, a snap hook 62, and an insert strip 63. Correspondingly, the base 1 can be provided with a mating groove 112, a snap-fit ​​groove, and an insert groove. During specific assembly, the insert strip 63 can be inserted into the insert groove to achieve the connection between the extension base 6 and the base 1 in the first direction. The snap hook 62 can be snapped into the snap groove to achieve the connection between the extension base 6 and the base 1 in the third direction. The mating block 61 can be snapped into the mating groove 112 to ensure the relative fixation of the extension base 6 and the base 1 in the second direction.

[0057] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
