Referring to fig. 1-5, a freestanding busway connector of the present invention is schematically shown, comprising a base 100, a compression beam 200, a racking mechanism 300, and a plurality of contact assemblies 400.

The pushing mechanism 300 is connected to the base 100 and the pressing beam 200, respectively, for driving the base 100 and the pressing beam 200 to move relatively in a first direction.

The plurality of contact assemblies 400 are disposed in the plurality of guide slots 220 in a one-to-one correspondence, i.e., one contact assembly 400 is disposed in each guide slot 220. The contact assembly 400 includes an elastic member 420 and two contact parts 410 disposed opposite to each other, and the contact parts 410 are slidably connected to the base 100 in a second direction, the first direction and the second direction being perpendicular to each other, which enables the two contact parts 410 of each contact assembly 400 to move toward or away from each other. The contact member 410 is slidably coupled to the inner sidewall of the guide groove 220, and a coupling surface between the contact member 410 and the inner sidewall of the guide groove 220 is disposed to be inclined to the first direction. Both sides of the elastic member 420 are connected to the two contact members 410, which are oppositely disposed, respectively. When the pushing mechanism 300 drives the pressing beam 200 and the base 100 to move relatively in the first direction, at this time, the pressing beam 200 moves toward the opening direction of the guide groove 220, and the inner side wall of the guide groove 220 drives the two oppositely disposed contact members 410 to move oppositely, so as to clamp the cable between the two oppositely disposed contact members 410.

Because each guide groove 220 is used for driving one contact assembly 400 to clamp a cable, when the pushing mechanism 300 drives the pressing beam 200 and the base 100 to move relatively in the first direction, the plurality of contact assemblies 400 can clamp and clamp the cable at the same time, the plurality of contact assemblies 400 cannot influence each other, the clamping force of the plurality of contact assemblies 400 is ensured to be balanced, and the problem that the two contact components 410 arranged oppositely incline to each other to cause poor flow guiding effect can be avoided.

Further, the insulating member 412 is provided with a mounting groove 4121, and as shown in fig. 5, the pressing block 411 is detachably embedded in the mounting groove 4121, so that when the pressing block 411 is worn seriously, the pressing block 411 can be removed and replaced.

The base 100 is provided with a guide 110 arranged along the second direction, the contact part 410 is slidably connected to the guide 110, specifically, the guide 110 is a cylindrical structure, a guide hole is provided on the contact part 410, and the guide 110 is slidably disposed through the guide hole.

The base 100 includes a connecting base 120 and two connecting arms 130 arranged in parallel, the connecting arms 130 are perpendicular to the connecting base 120, and the two connecting arms 130 are respectively connected to two ends of the connecting base 120, so that the base 100 is U-shaped.

The base 100 of the structure can surround the pressing beam 200, and not only can be used for installing and supporting the pressing beam 200, but also can protect the pressing beam 200.

The pushing mechanism 300 includes a screw 310 and a connecting block 320, the screw 310 is connected to the base 100 through a screw fit, specifically, a threaded hole is formed in the base 100, the screw 310 is movably connected to the threaded hole in a fit manner, and the screw 310 can move relative to the base 100 in an axial direction when rotating around an axis thereof. The connecting block 320 is detachably connected to the pressing beam 200, one end of the screw 310 is rotatably connected to the connecting block 320, the screw 310 is rotated to push the connecting block 320 to move in a first direction, so that the pressing beam 200 is forced to move in the first direction relative to the base 100, and the connecting block 320 is further used for uniformly applying the top pushing force applied to the connecting block 320 by the screw 310 on the pressing beam 200.
