Fig. 1 is a schematic view of a bus bar connection assembly according to one embodiment of the present utility model, and fig. 2 is an exploded view of the bus bar connection assembly of fig. 1. Referring to fig. 1 and 2, the bus connecting assembly mainly comprises a flexible bus 1 and a fixing member 2, and it should be noted that the flexible bus 1 is used for collecting, distributing and transmitting electric energy and can be bent to a certain extent, and has been widely used in power distribution equipment, such as a power distribution cabinet, a power cabinet, a ring main unit, and the like. The flexible bus 1 includes a bus body 11 that is curved, and in practical application, the bus body 11 mainly comprises a conductive cable and an insulating sheath wrapped around the conductive cable, for example, the conductive cable adopts a copper wire, and the insulating sheath adopts a rubber sheath.

It will be appreciated that the conductive cable can be bent, and accordingly, the busbar body 11 can also be bent, and after the busbar body 11 is bent to the bending radian required for installation, in order to avoid rebound of the bent busbar body 11, in particular, by providing the fixing member 2 extending in the bending direction of the busbar body 11 on one side of the busbar body 11, the fixing member 2 is provided to the bending radian required for installation so that the bending radian of the busbar body 11 is consistent with the bending radian required for installation, and the busbar body 11 is kept in the bending setting.

Further, the fixing member 2 is provided on a side away from the bending center of the busbar body 11. For convenience of explanation, the side far from the bending center of the busbar body 11 is the outside, the side near the bending center of the busbar body 11 is the inside, and both ends of the busbar body 11 in a bent shape have a tendency to rebound outward. The fixing piece 2 is arranged on the top side, the bottom side and the outer side of the bus body 11, so that the bus body 11 is kept in a bent arrangement, and the fixing piece 2 is preferably arranged on the outer side of the bus body 11, so that the assembly of workers is facilitated.

Note that, referring to fig. 1 and 2, the busbar body 11 is curved in an arc shape, and the bending center of the busbar body 11 is the center of the arc-shaped busbar body 11.

As described above, the bus bar body 11 is maintained in a bent arrangement by the fixing member 2, and therefore, it is preferable that the bending rigidity of the fixing member 2 is greater than that of the bus bar body 11, in other words, the fixing member 2 is stronger in resistance to bending deformation than the bus bar body 11, so that the bus bar body 11 can be maintained in a bent state by the fixing member 2.

In the present disclosure, the fixing member 2 is sleeved on the busbar body 11 and clamps the busbar body 11. Specifically, referring to fig. 1 and 2, in the illustrated embodiment, the busbar body 11 is a circular line, and accordingly, the fixing member 2 is a plate member with a radial cross-section that is circular arc and extends along an axial curve, in addition, in order to be able to be normally clamped on the busbar body 11 and ensure a contact area between the fixing member 2 and the busbar body 11 as much as possible, the radial cross-section of the fixing member 2 is preferably semicircular, of course, the inner diameter of the radial cross-section of the fixing member 2 is slightly smaller than the outer diameter of the busbar body 11, and the two form interference fit, so that the fixing member 2 is ensured to be clamped on the busbar body 11 and not easy to fall off.

Further, the fixing member 2 is provided with an anti-slip hole a, and the busbar body 11 includes an insulating sheath, typically a rubber sheath, located on the outer ring as described above. In an alternative embodiment, after the fixing member 2 is sleeved on the bus body 11, the rubber sheath is deformed and embedded in the anti-slip hole A due to interference fit between the fixing member 2 and the bus body 11, so that an anti-slip effect is achieved, and subsequent installation is facilitated.

Referring to fig. 1 and 2, the anti-slip hole a is only provided with one, and in case that the number of the anti-slip holes a is only one, the anti-slip holes a are suitable in size, so that a certain anti-slip effect can be achieved, preferably, the anti-slip holes a are arranged in the middle of the fixing member 2, so that deformation embedding amount of the rubber sheath can be guaranteed, and the bus body 11 is prevented from sliding relative to the fixing member 2. Of course, the number of the anti-slip holes a may be plural, and accordingly, the size of the anti-slip holes a may be appropriately reduced, and the number of the anti-slip holes a is not particularly limited herein.

Of course, the anti-slip purpose can be achieved by other structures, for example, anti-slip lines are arranged on the surface of the fixing piece 2 connected with the bus body 11, and the anti-slip effect can be achieved.

In an alternative embodiment, where the number of the anti-slip holes a is only one, it is preferable to provide the anti-slip holes a in the middle of the fixing member 2, and the anti-slip holes a not only play a role in anti-slip, but also play a role in positioning, and specifically connect the anti-slip holes a with the middle of the busbar body 11. Further, referring to fig. 3, the clip member 3 is preferably disposed at the anti-slip hole a, so as to further strengthen the connection between the fixing member 2 and the bus body 11, that is, the clip member 3 is located in the middle of the bus body 11, thereby ensuring consistency. Of course, the mounting position of the clip member 3 is not limited to this, and a plurality of clip members 3 may be theoretically provided to further secure connection stability, and accordingly, the cost may be increased.

In the utility model, the flexible bus bar 1 further comprises a connecting terminal 12, and both ends of the bus bar body 11 are connected with the connecting terminal 12. The terminals 12 are used to connect with other power distribution elements, such as connectors.
