[0023] Reference Figure 1-Figure 3 , shows a bus duct joint structure of the present invention, including a protective sleeve 10 and a conductor 20, the number of the conductors 20 corresponding to the number of the bus duct conductive bars 70, the protective sleeve 10 is provided with an activity space, the conductor 20 is passed through the protective sleeve 10 and has a gap with the inner wall of the activity space, the top and bottom of the conductor 20 are respectively connected to the inner wall of the protective sleeve 10 by elastic members 30, and the two ends of the conductor 20 are respectively provided with a conductive groove 21, and the conductive groove 21 is plugged into the bus duct conductive bar 70;

[0024] The protective sleeve 10 and the conductor 20 are correspondingly provided with connecting holes, a connecting screw 40 is passed through the connecting hole, and the protective sleeve 10 is slidably sleeved on the connecting screw 40; two adjacent protective sleeves 10 are docked via a retractable male and female docking assembly 60.

[0025] In an embodiment of the present application, through the protective sleeve 10 and the conductor 20, the number of the conductors 20 corresponds one-to-one to the number of the bus duct conductive bars 70, and an activity space is provided in the protective sleeve 10. The conductor 20 is inserted into the protective sleeve 10 and has a gap with the inner wall of the activity space. The top and bottom of the conductor 20 are respectively connected to the inner wall of the protective sleeve 10 through an elastic member 30, and conductive grooves 21 are respectively provided at both ends of the conductor 20, and the conductive grooves 21 are plugged into the bus duct conductive bars 70; the protective sleeve 10 and the conductor 20 are correspondingly provided with connecting holes, and a connecting screw 40 is inserted into the connecting hole, and the protective sleeve 10 is slidably sleeved on the connecting screw 40; the two adjacent protective sleeves 10 are docked through a retractable male-female docking assembly 60. Power transmission is achieved by connecting the conductor 20 with the bus duct conductive bar 70; by arranging a protective sleeve 10 outside the conductor 20 and opening an activity space for the conductor 20 to move, when vibration occurs, the conductor 20 can be displaced synchronously with the conductive bar 70 in the activity space, avoiding relative displacement between the conductor 20 and the conductive bar 70 during vibration, thereby generating a gap that affects power transmission; and by setting the protective sleeve 10, on the one hand, the vibration of the conductor 20 and the bus duct can be limited to avoid large shaking, and on the other hand, it can protect the conductor 20; by slidingly connecting the protective sleeve 10 and the conductor 20 to the connecting screw 40, the spacing can be adjusted to adapt to different types of bus duct docking; the sliding protective sleeve 10 is limited and connected by the retractable male and female docking assembly 60 to increase the connection stability. The present application can reduce the impact of vibration on bus duct docking, making the bus duct connection more stable and having a wide range of applications.

[0026] Next, a bus duct joint structure in this exemplary embodiment will be further described.

[0027] In this embodiment of the present application, the protective sleeve 10 is provided with a movable space. The conductor 20 is inserted into the protective sleeve 10 and has a gap with the inner wall of the movable space. The top and bottom of the conductor 20 have gaps with the inner wall of the protective sleeve 10, allowing the conductor 20 to move up and down within the movable space. After the conductor 20 is connected to the bus duct conductive bar 70, when vibration occurs, the movement of the conductive bar 70 can drive the conductor 20 to move synchronously, preventing relative displacement between the conductor 20 and the conductive bar 70 and the formation of a gap. The top and bottom of the conductor 20 are respectively connected to the inner wall of the protective sleeve 10 by elastic members 30. The conductor 20 has conductive slots 21 at each end, which are plugged into the bus duct conductive bar 70. By providing the elastic member 30 between the protective sleeve 10 and the conductor 20, when the conductor 20 moves with the conductive bar 70, the elastic member acts as a shock absorber, preventing direct collision between the conductor 20 and the protective sleeve 10. Specifically, the elastic member 30 is a shock-absorbing spring, and at least four shock-absorbing springs are provided at the top and bottom of the conductor 20. Specifically, two shock-absorbing springs are provided at intervals at the top and two at the bottom. The elastic action of the shock-absorbing springs can buffer and reduce vibrations, and the conductor 20 can be reset under the action of the elastic restoring force.

[0028] In an embodiment of the present application, the protective sleeve 10 and the conductor 20 are provided with corresponding connection holes, and a connecting screw 40 is passed through the connection hole, and multiple protective sleeves 10 and conductors 20 are connected by the connecting screw 40. The protective sleeve 10 is slidably sleeved on the connecting screw 40; two adjacent protective sleeves 10 are docked by a retractable male-female docking assembly 60. By slidingly connecting the anti-slip sleeve and the conductor 20 to the connecting screw 40, the distance between the multiple protective sleeves 10 can be adjusted, and the adjacent protective sleeves 10 are connected by the retractable male-female docking assembly 60, and the protective sleeves 10 are connected and limited, so that the joint structure can be applied to different types of bus duct connections. Specifically, when the spacing needs to be adjusted, the protective sleeve 10 is moved so that the male-female docking assembly 60 is extended or shortened to a suitable position and fixed, and the protective sleeve 10 and the conductor 20 can be adjusted to a suitable position.

[0029] As an example, it further includes a connecting plate 50, which is sleeved on both ends of the connecting screw 40 and is used to connect to the housing of the bus duct; the connecting plate 50 and the adjacent protective cover 10 are connected via the male and female docking assembly 60. The joint structure is connected to the housing of the bus duct via the connecting plates 50 at both ends. Specifically, the connecting plate 50 and the bus duct housing can be connected by bolts and nuts to facilitate assembly and disassembly. The connecting screw 40 and the connecting plate 50 can be locked with a nut or a limit block can be set to prevent the connecting screw 40 from detaching from the connecting plate 50, protective cover 10 and other structures.

[0030] As an example, the male-female docking assembly 60 includes a male connector 61 and a female connector 62. The female connector 62 has a female groove 621, and the male connector 61 can be retractably inserted into the female groove 621. The retractable insertion of the male connector 61 and the female connector 62 simplifies assembly and disassembly, and makes the connection between the protective sleeves 10 more stable, preventing the threaded connection from loosening under vibration.

[0031] Furthermore, the inner wall of the female groove 621 is provided with a plurality of snap-in grooves 622, and the outer wall of the male connector 61 is provided with a clamping block 611, and the clamping block 611 is adapted to the snap-in groove 622. By setting a plurality of snap-in grooves 622 and respectively adapted to the clamping block 611, when the spacing needs to be adjusted, the clamping block 611 can be connected to different snap-in grooves 622 to make it at different telescopic lengths. Among them, the spacing between the snap-in grooves 622 can be set according to the spacing between the conductive bars 70 of different types of bus ducts so that they correspond to each other. When the structure is applied to a certain type of bus duct, it can be adjusted to the corresponding snap-in position. In the embodiment of the present application, other telescopic connection methods can also be used to connect the male connector 61 and the female connector 62.

[0032] As an example, the male connector 61 and the female connector 62 are both rectangular in shape. The male connector 61 defines a rectangular through-hole 612. The connection between the connecting screw 40 and the protective sleeve 10 defines a rectangular portion 41, which mates with the rectangular through-hole 612. Providing multiple rectangular portions 41 on the connecting screw 40, each correspondingly connected to the rectangular holes defined in the protective sleeve 10, prevents the multiple protective sleeves 10 from rotating during use, thereby improving connection stability.

[0033] As an example, the protective sleeve 10 is made of an insulating heat-dissipating material. The conductor 20 is disposed within the protective sleeve 10 and generates heat during operation. This heat is dissipated through the gaps in the active space and also through the protective sleeve 10 made of the heat-dissipating material, thereby improving heat dissipation performance and extending its service life.

[0034] As an example, the length of the conductor 20 is smaller than the length of the protective sleeve 10 , so that the conductor 20 is entirely located inside the protective sleeve 10 , and the protective sleeve 10 provides effective protection therefor.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
