The busbar connection assembly includes two connection frames, a fire-resistant castable body, and several connection conductors. By rotating the locking mechanism, the central rod drives the insulating inner sleeve to move, and the moving insulating inner sleeve drives the conductor connection plate to move, thereby adjusting the angle between the connection conductor and the conductor connection plate, so as to adjust the busbar connector to a direct connection type or an adapter type according to actual needs.

[0004] During the installation and docking process, the aforementioned busbar connectors are fixed by bolts and nuts to the busbar connection components. After the nuts are removed, their placement needs to be carefully monitored, and the nuts are also very easy to lose during operation, resulting in inconvenience in fixing the connection.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0028] The following is combined Figures 1 to 4 This invention describes a double-joint flexible connection device for busbar trunking suitable for seismic isolation nodes (hereinafter referred to as the "flexible connection device").

[0029] Figure 1 This is a perspective view of the double-joint flexible connection device for busbar trunking suitable for seismic isolation nodes provided by this utility model, as shown below. Figure 1 As shown, the flexible connection device includes a busbar connection assembly 1, a first busbar connector 2, and a second busbar connector 3.

[0030] The bus connection assembly 1 has a first end and a second end. A first bus connector 2 is connected to the first end of the bus connection assembly 1, and a second bus connector 3 is connected to the second end of the bus connection assembly 1. For the bus connection assembly 1, each of its first and second ends is provided with a slot 11; for the first bus connector 2 and the second bus connector 3, a connecting component 4 is provided at their ends, particularly corresponding to the slot 11. The connecting component 4 engages with the side surface of the corresponding bus connector, clamping the end wall of the bus connection assembly 1 near the slot 11. Thus, with the engagement of the connecting component 4 (and the side surface of the corresponding bus connector) with the slot 11, the connection between the bus connection assembly 1 and the first bus connector 2 / second bus connector 3 is locked / retained.

[0031] The flexible connection device also includes a limiting component 5. The limiting component 5 is associated with the end wall of the first bus connector 2 / second bus connector 3; specifically, only one limiting component 5 needs to be configured on each end wall. The limiting component 5 is connected to the top of the connecting component 4. In particular, each end wall may be configured with multiple connecting components 4; in this case, a single limiting component 5 is connected to the top of all connecting components 4. Thus, any component of the connecting component 4 is constrained by the limiting component 5 and cannot detach from the position of the connecting component 4.

[0032] With the above configuration, when the connecting component 4 is operated (e.g., disassembled), its components can never be removed from the movable range defined by the limiting component 5, thereby maintaining the integrity of the components of the first bus connector 2 and the second bus connector 3, without requiring the operator to spend extra effort to pay attention to whether the disassembled components are still in place.

[0033] Figure 2 yes Figure 1 The exploded view shown is a partial view of a double-joint flexible connection device for busbar trunking suitable for seismic isolation nodes. The second busbar connector is shown in the exploded view. Figure 2As shown, the connection between the bus connection assembly 1 and the first bus connector 2 and the second bus connector 3 is an insertion connection. The first and second ends of the bus connection assembly 1 have multiple end walls, thus forming wiring holes at both ends; the first bus connector 2 and the second bus connector 3 are constructed as connecting shafts so that the operator can quickly align the corresponding bus connectors with the bus connection assembly 1 when connecting the bus connection assembly 1, the first bus connector 2 and the second bus connector 3.

[0034] Furthermore, the number of slots 11 at the first end and the second end is plurality, and a plurality of slots 11 are distributed on at least one end wall of the first end or the second end. In particular, from Figure 2 It can be seen that the second end of the busbar connection assembly 1, which has a square cross-section, has two slots 11 not only on its top end wall, but also on its bottom end wall.

[0035] It can be inferred that, correspondingly, the second bus connector 3 not only has two connecting components 4 at its top corresponding to the slot 11, but also has two connecting components 4 at its bottom.

[0036] Of course, in other embodiments, for other purposes, such as to further improve the locking force of the connecting component 4 between the bus connecting component 1 and the corresponding bus connector, the slot 11 configured on the end wall of the bus connecting component 1 and the connecting component 4 configured on the end face of the corresponding bus connector may also have other combinations.

[0037] Figure 3 yes Figure 2 The enlarged view of detail A shown is as follows: Figure 3 As shown, the connecting assembly 4 includes a threaded rod 41 connected to the first bus connector 2 or the second bus connector 3, and a fixing nut 42 threadedly engaged with the threaded rod 41. Since the threaded rod 41 is connected to the first bus connector 2 or the second bus connector 3, it will not disengage from either connector. A limiting component 5 is connected to the top of the connecting assembly 4, particularly the top of the threaded rod 41. With the fixing nut 42 threadedly engaged with the threaded rod 41, when the fixing nut 42 is screwed to the top of the threaded rod 41, the fixing nut 42 is constrained by the limiting component 5 and cannot detach from the threaded rod 41. This configuration avoids the risk of losing the fixing nut 42 during operation of the connecting assembly 4, and also eliminates the need for operators to spend time checking whether the fixing nut 42 is still in place after removing it.

[0038] Conversely, when the operator operates the connection assembly 4 to lock the connection between the bus connection assembly 1 and the first bus connector 2 and the second bus connector 3, the retaining nut 42 is screwed into contact with the end wall near the slot 11 of the bus connection assembly 1. In this way, the retaining nut 42 and the end face of the corresponding bus connector clamp the end wall near the slot 11 from both sides, thereby providing the fastening / locking force required to maintain the connection state of the bus connection assembly 1 and the corresponding bus connector.

[0039] Furthermore, the outer wall of the fixing nut 42 is provided with a plurality of protrusions 43 extending radially therefrom, and the end of each protrusion 43 is formed as an anti-slip surface 44. The protrusions 43 are distributed circumferentially on the outer wall of the fixing nut 42 at fixed intervals. For example, the fixing nut 42 is provided with four protrusions 43, and every two adjacent protrusions 43 are spaced 90° apart from each other in the circumferential direction; of course, in other embodiments, other numbers and spacing angles are also feasible. When an operator operates the fixing nut 42, the anti-slip surface 44 on the protrusions 43 is contacted by the operator, thereby stably rotating the fixing nut 42 to rise or fall along the thread.

[0040] Furthermore, the lower end of the threaded rod 41 is provided with a pivot portion 411, which has a shaft hole (not shown in the figure) so that the rotating shaft 412 passes through the shaft hole and is thus mounted in the pivot portion 411. With the above configuration, the main body of the threaded rod 41 can pivot relative to the rotating shaft 412.

[0041] Mounting blocks 413 are provided at both ends of the rotating shaft 412, and the rotating shaft 412 is rotatably or fixedly connected to these mounting blocks 413. On the other hand, the mounting blocks 413 are fixedly connected (e.g., welded) to the side surfaces of the first bus connector 2 and the second bus connector 3.

[0042] With the above configuration, the threaded rod 41 is pivotally and non-removably connected to the side surface of the corresponding bus connector. As mentioned above, the busbar duct passes through structurally weak areas such as building isolation layers and isolation trenches, and the two bus connectors belong to different independent swaying systems, resulting in relative displacement in the vertical and horizontal directions. The movable connection between the threaded rod 41 and the side surface of the corresponding bus connector can absorb / buffer the energy between the two independent swaying systems to a certain extent, thereby maintaining the connection between the bus connection assembly 1 and the first bus connector 2 / second bus connector 3.

[0043] Figure 4 yes Figure 2 The enlarged view of detail B shown is as follows: Figure 4As shown, the limiting assembly 5 includes a strip-shaped member 51 and a stud 53, wherein the stud 53 is rotatably connected to the strip-shaped member 51 via a bearing 52. As described above, only a single limiting assembly 5 is required for each end wall. The single limiting assembly 5 includes a single strip-shaped member 51, which has several through holes (not shown in the figure). The number / position of these through holes corresponds to the number / position of the connecting assemblies 4 on that end wall. For each through hole, the outer ring of the bearing 52 is fixedly connected to the hole wall, and the inner wall of the bearing 52 is fixedly connected to the stud 53.

[0044] With the above configuration, the stud 53 is rotatably connected to the strip member 51 for threaded connection with the connecting assembly 4, as will be described below; moreover, the tops of all connecting assemblies 4, i.e., all threaded rods 41, are connected to the limiting assembly, and the retaining nut 42, moving upward along the thread, is eventually stopped by the strip member 51, thus preventing it from disengaging from the connecting assembly 4. Furthermore, without disassembling the limiting assembly 5, the operator can pull the limiting assembly 5 to drive the connecting assembly 4 of the first busbar connector 2 and the second busbar connector 3, causing the connecting assembly 4 to enter and engage with the slot 11 of the busbar connecting assembly 1.

[0045] Furthermore, a knob 54, such as a T-shaped knob, is provided at the top of the stud 53. The knob 54 and the stud 53 can be integrally formed or fixedly connected to each other. Thus, when the operator rotates the knob 54, the stud 53 rotates together with the knob 54.

[0046] Furthermore, the top end of the threaded rod 41 has an axial hole 414 extending along its own axial direction (i.e., longitudinal direction). The axial hole 414 is provided with internal threads so that the axial hole 414 mates with the stud 53. Thus, the connection between the limiting assembly 5 and the connecting assembly 4 is detachable. If necessary, the operator can operate the knob 54 to disengage the threaded connection between the stud 53 and the axial hole 414 of the threaded rod 41. After removing the limiting assembly 5, especially the strip member 51, the retaining nut 42 in the connecting assembly 4 can be removed and replaced.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
