[0047] Further, and from the structure, this state can adapt to more cases, and can be matched with different external structures through the state of holding interference, and the strength of the structure as a whole is not dependent on the fixing strength, but can achieve a good stable state through the shape structure.

[0048] The vertical rods of the first assembly 100a and the second assembly 100b are inconsistent, especially on the side close to the busbar, and need to be connected stably through clamping and structure.

[0049] Embodiment 3

[0051] The horizontal rod of the first assembly 100a and the second assembly 100b can contact and fix on both sides of the busbar, and the cooperation of the vertical rod and the horizontal rod can protect and surround the busbar in full area and full direction.

[0052] Embodiment 4

[0053] Refer to Figures 1-4 For the fourth embodiment of the utility model, the embodiment is based on the previous embodiment, and different from the previous embodiment is that the contact part of the first assembly 100a is provided with a curved groove 100a-1, which is surrounded by a first protrusion A and a second protrusion B, that is, the concave surface formed between the two protrusions, that is, the curved groove 100a-1, and the inner wall of the curved groove 100a-1 is relatively smooth, which can well bear the state change or displacement of the arc-shaped component fitted therewith;

[0054] The curved groove 100a-1 is internally provided with the pin shaft 101 which is slidingly connected with the inner wall, that is, the pin shaft 101 is the part which contacts other parts and completes the auxiliary connection and fixing of the state change in the curved groove 100a-1, and the characteristic is that the rotation or relative displacement in the curved groove 100a-1 can be better completed.

[0055] Further, the second assembly 100b is provided with an opening 100b-1 at the end thereof, and the opening 100b-1 faces the opening of the curved groove 100a-1, and it can be understood that the downward displacement of the second assembly 100b can enter the curved groove 100a-1.

[0056] In detail, the second assembly 100b can enter the curved groove 100a-1 and contact the pin shaft 101, so that the pin shaft 101 rotates in the curved groove 100a-1 and is clamped into the opening 100b-1, and the special structure of the pin shaft 101 can enable the pin shaft 101 to perform surface fitting arc motion in the curved groove 100a-1, and the motion process can guide the pin shaft 101 to rotate around the curved groove 100a-1 as the center, and under the influence of the end of the second assembly 100b, the pin shaft 101 is pushed and enters the opening 100b-1 under the assistance of the semicircular arc structure thereof, and after entering the opening, the two assemblies are not fixedly connected and need the assistance of other components to form the effect.

[0057] In detail, the inner wall of the opening 100b-1 can be fitted to the side of the pin shaft 101 facing the end of the second assembly 100b, and after the pin shaft 101 rotates, the part fitted into the inner wall of the opening 100b-1 can be parallel to the inner wall of the opening 100b-1 and form a state in which the opening 100b-1 is limited by the pin shaft 101. After being limited, except for the limited part, the end of the second assembly 100b-1 and the pin shaft 101 completely fill the opening circular groove type of the curved groove 100a-1 in the curved groove 100a-1, and further limitation is formed. To stabilize this state, some other components need to be filled in the space between the two assemblies and the busbar.

[0058] The fixed shell 100 is made of aluminum alloy material to ensure the heat dissipation and strength of the whole structure.

[0059] Embodiment 5

[0060] Reference Figures 1-4 For the fifth embodiment of the utility model, the embodiment is based on the previous embodiment, and a bus duct filling body is provided, and the difference from the previous embodiment is that a sealing element 200 is arranged in the interval space S of the bus duct shell, and the interval space S can be understood as the remaining large space gap between the first assembly 100a, the second assembly 100b and the busbar based on the limiting structure.

[0061] In detail, the interval space S includes,

[0062] The projection of the contact part of the first assembly 100a to the busbar is a first interval S1, which can be understood as the interval space S. Figure 3The cross section of the projection part can be seen at which position, and the cross section area can also be directly the distance between the busbar and the contact part of the first assembly 100a and the height of the contact part of the first assembly 100a.

[0063] The distance h1 between the end of the contact part of the first assembly 100a and the plane of the first protrusion A is the projection of the contact part of the second assembly 100b, which is the second interval S2, which can also be obtained from Figure 3 The cross section state can be simply understood as the non-connection part of the contact part of the first assembly 100a and the plane of the width of the first protrusion A;

[0064] The height difference h2 between the contact part of the first assembly 100a and the plane of the busbar is the projection of the two sides close to the busbar and the second assembly 100b, which is the third interval S3, which can also be obtained from Figure 3 When viewed from above, after the fixed connection of the first assembly 100a and the second assembly 100b is completed, the remaining part is the third interval S3 except for other parts that have been described.

[0065] Embodiment 6

[0066] Referring to Figures 1-5 For the sixth embodiment of the utility model, this embodiment is based on the previous embodiment, and provides a busbar slot frame assembly, and the difference from the previous embodiment is that the sealing element 200 is composed of a side sealing part and a supplementary part connected to the side sealing part.

[0067] The side sealing part can fill the first interval S1 and the second interval S2, that is, the filler filling the vertical direction part can be seen from the drawings.

[0068] The supplementary part can fill the third interval S3, that is, the filler in the horizontal direction.

[0069] The sealing element 200 can be roughly understood as a U-shaped rubber material, and the reason why it can assist in forming the connection of the two assemblies is that the first assembly 100a and the second assembly 100b in the hooked connection state can form a fixed connection state without dead corners, without direct hard collision area, and without unlocking space caused by secondary contact under the filling of the flexible sealing element 200. This result does not rely on any existing hard riveting connection, but completely relies on the structure characteristics and material utilization to form this efficient connection result.
