[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] Embodiment 1

[0028] See also Figure 1 , 3 As shown, the utility model is a compact and intensive bus duct, comprising a main conductive bar 1, a protective assembly 2 is sleeved on the outer side of the main conductive bar 1, and the protective assembly 2 includes a left protective shell 21 sleeved on one side of the outer side of the main conductive bar 1, and a right protective shell 22 arranged on the side of the left protective shell 21 is sleeved on the other side of the outer side of the main conductive bar 1, which effectively simplifies the number of components of the protective assembly 2 and the assembly steps of the protective assembly 2, which is conducive to speeding up the assembly efficiency of the protective assembly 2, and indirectly improves the assembly efficiency of the compact and intensive bus duct;

[0029] Among them Figure 1 , 2 As shown, the outer side walls of the conductive busbars 11 fixed at both ends of the main conductive bar 1 are provided with anti-skid teeth 111 at equal intervals. The anti-skid teeth 111 effectively prevent the conductive busbars 11 from sliding longitudinally during the connection process, greatly improving the stability of the conductive busbars 11 after connection;

[0030] Among them Figure 3 As shown, the inner wall of the protective gasket 221 sleeved on the inner wall of the left protective shell 21 and the right protective shell 22 contacts the outer wall of the main conductive bar 1, and the protective gasket 221 effectively prevents the left protective shell 21 and the right protective shell 22 from directly contacting the main conductive bar 1, thereby reducing the wear of the left protective shell 21 and the right protective shell 22 when they move along the main conductive bar;

[0031] Among them Figure 3 , 4 As shown, a circular plug shell 212 is fixedly connected to the side wall of the left protective shell 21 close to the right protective shell 22, and a circular slot 222 is provided on the side wall of the right protective shell 22 close to the left protective shell 21. The circular plug shell 212 is plugged into the circular slot 222, so that when the ends of the left protective shell 21 and the right protective shell 22 are not in contact, the main conductive bar 1 is still fully protected;

[0032] The inner wall of the circular slot 222 is connected to the limit spring 224 in a rectangular array, and the end of the limit spring 224 passes through the through hole opened in the rectangular array on the side wall of the circular plug shell 212 and abuts against the side wall of the left protective shell 21, so as to facilitate the adjustment of the distance between the left protective shell 21 and the right protective shell 22;

[0033] The left protective shell 21 is provided with a plug rod 213 in a rectangular array near the side wall of the right protective shell 22, and the right protective shell 22 is provided with a plug hole 223 in a rectangular array near the side wall of the left protective shell 21. The plug rod 213 is plugged into the plug hole 223, which effectively limits the trajectory of the left protective shell 21 and the right protective shell 22 when they move, and improves the stability of the left protective shell 21 and the right protective shell 22 when they move;

[0034] The circular limiting plates 211 fixedly connected to the side walls of the left protective shell 21 and the right protective shell 22 are in contact with the two ends of the main conductive bar 1. The circular limiting plates 211 effectively limit the length of the left protective shell 21 and the right protective shell 22 sleeved outside the main conductive bar 1, and conveniently limit the positions of the left protective shell 21 and the right protective shell 22 outside the main conductive bar 1.

[0035] When the above-mentioned arrangement is used, the left protective shell 21 and the right protective shell 22 are sleeved on the two ends of the outside of the main conductive bar 1, and external forces are applied to the left protective shell 21 and the right protective shell 22 until the circular limit plate 211 abuts against the ends on both sides of the main conductive bar 1. During the movement of the left protective shell 21 and the right protective shell 22, the limit spring 224 contracts, the insertion rod 213 is plugged into the socket 223, and the circular plug shell 212 is plugged into the circular slot 222, thereby completing the assembly of the protective component 2; otherwise, the protective component 2 is disassembled.

[0036] Embodiment 2

[0037] The difference between the second embodiment and the first embodiment is that the second embodiment further discloses: Figure 1 , 3 As shown in FIG. 4 , the front and rear side walls of the left protective shell 21 are symmetrically provided with a connecting assembly 3 near one end of the right protective shell 22. The connecting assembly 3 includes a connecting strip 31 and a convex handle 32. The connecting strip 31 is connected to the side wall of the left protective shell 21 near one end of the right protective shell 22. The side of the connecting strip 31 away from the left protective shell 21 passes through the right positioning rod 322. One end of the return spring 321 sleeved on the outer side of the positioning rod 322 is connected to the outer side of the connecting strip 31. The inner side of the convex handle 32 fixed to the outer end of the positioning rod 322 is connected to the other end of the return spring 321. The front and rear side walls of the right protective shell 22 are close to the right protective shell 22. Positioning holes 225 are provided at equal intervals near one end of the left protective shell 21, and the end of the positioning rod 322 away from the protrusion 32 is plugged into the positioning hole 225, so that the distance between the left protective shell 21 and the right protective shell 22 can be adjusted according to the actual size of the main conductive bar 1. By adjusting the plugging between the positioning rod 322 and different positioning holes 225, the distance between the left protective shell 21 and the right protective shell 22 is limited, so that the left protective shell 21 and the right protective shell 22 can protect the main conductive bars 1 of different sizes, thereby improving the application range of the protective assembly 1 and improving the practicality.

[0038] When the above arrangement is used, when the left protective shell 21 and the right protective shell 22 move toward each other, the positioning rod 322 moves toward the positioning hole 225, and an external force is applied to the cam 32 in a direction away from the connecting strip 31, and the return spring 321 stretches until the inner end of the positioning rod 322 is flush with the inner side of the connecting strip 31, and the left protective shell 21 and the right protective shell 22 continue to move toward each other until the return limit plate 211 abuts against the two ends of the main conductive bar 1, and the cam 32 is released, the return spring 321 contracts, and the positioning rod 322 is inserted into the positioning hole 225, thereby completing the locking connection between the left protective shell 21 and the right protective shell 22; conversely, the locking connection between the left protective shell 21 and the right protective shell 22 by the positioning rod 322 is released.

[0039] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
