[0007] The positioning structure includes at least one positioning groove and a positioning block. The positioning groove is located on a partition inside the switch body. The positioning block is located on the top of the first side arm of the clamp and can be adapted to connect with the positioning groove.

[0008] The busbar clamp assembly is installed in the sleeve by a limiting structure. The limiting structure includes a limiting block on the outer side of the second side arm of the busbar clamp assembly and a limiting groove on the inner side of the first side arm of the sleeve that can be adapted to and connected with the limiting block. The limiting groove extends along the height direction of the first side arm.

[0009] The jacket has a first opening and a second opening located on both sides of its length, through which the conductive busbar can pass.

[0010] The jacket is provided with a conductive component suitable for connecting the incoming busbar and the conductive busbar. The conductive component is fixedly installed on the jacket through a plug-in structure.

[0011] The plug-in structure includes a first plug, a second plug, a slot, and a second opening. The first plug and the second plug are respectively located on both sides of the conductive component along its length. The slot and the second opening are respectively located on both sides of the sleeve along its length and are respectively plugged into the first plug and the second plug.

[0012] The bottom surface of the switch body is detachably equipped with multiple sealing plates for shielding the conductive busbar.

[0013] The sealing plate is fixedly installed on the conductive busbar by an elastic hook structure. The elastic hook structure includes an elastic arm on the top surface of the sealing plate and a hook on the elastic arm that can abut against the top surface of the conductive busbar.

[0014] The sealing plate includes a sealing plate body and a baffle portion provided on one side of the sealing plate body and extending toward the adjacent sealing plate. The baffle portion extends to the inner side of the sealing plate body and can abut against the busbar clamp assembly.

[0040] Example

[0041] This embodiment provides a disconnecting switch that can be connected to an adjustable phase fuse, such as... Figure 1 and 2 As shown, it includes a switch body 1, a busbar clamp assembly 3, a sleeve 4, a conductive component 5, and a sealing plate 6.

[0042] Switch body 1, such as Figure 1 , 2 As shown in Figures 4, 5, 6, and 9, a conductive busbar 2 and a busbar clamp assembly 3 are provided on it. The busbar clamp assembly 3 can move along the length direction of the conductive busbar 2 and is suitable for clamping the incoming busbar. The partition 12 inside the switch body 1 is provided with three positioning slots 11. A limiting block 32 is provided on the outer side of the second side arm 31 of the busbar clamp assembly 3. The switch body 1 has an upper incoming position for the upper incoming line and a lower incoming position that is rotated 180° relative to the upper incoming position and is suitable for the lower incoming line. The orientation of the busbar clamp assembly 3 at the upper and lower incoming positions is the same.

[0043] Jacket 4, such as Figure 2-7 As shown, the clamp 4 is fitted onto the busbar clamp assembly 3. The top of the first side arm 42 of the clamp 4 is provided with a positioning block 41 that can be adapted to and connected to the positioning groove 11. The first side arm 42 is provided with a first elongated hole 47 adjacent to the positioning block 41. The inner side of the first side arm 42 of the clamp 4 is provided with a limiting groove 43 that can be adapted to and connected to the limiting block 32. The limiting groove 43 extends along the height direction of the first side arm 42. The clamp 4 has a first opening 44 and a second opening 45 respectively provided on both sides of its length direction, through which the conductive busbar 2 can pass. The baffle 48 on the side of the clamp away from the second opening 45 is provided with a slot 46. The baffle 48 is provided with a second elongated hole 49 on both sides.

[0044] Conductive component 5, such as Figure 4-6 As shown, the conductive element 5, located within the sleeve 4, is adapted to connect the incoming busbar and the conductive busbar 2. The conductive element 5 has a first insertion block 51 and a second insertion block 52 on both sides along its length. The first insertion block 51 and the second insertion block 52 are respectively inserted into the slot 46 and the second opening 45. Since the connecting plate 7 below the second opening 45 of the sleeve 4 separates the conductive busbar 2 and the incoming busbar, the conductive element 5 needs to be installed on the sleeve 4. The bottom surface of the conductive element 5 is lower than the bottom surface of the connecting plate 7, so that the conductive element 5 can connect the conductive busbar 2 and the incoming busbar.

[0045] Sealing plate 6, such as Figure 2 and 8 As shown, the sealing plate is detachably installed at the bottom of the switch body 1. The sealing plate is used to cover the conductive busbar 2. The sealing plate 6 is fixedly installed on the conductive busbar 2 by an elastic hook structure. The elastic hook structure includes an elastic arm 61 provided on the top surface of the sealing plate 6, and a hook 62 provided on the elastic arm 61 that can abut against the top surface of the conductive busbar 2. The sealing plate 6 includes a sealing plate body 63, and a baffle portion 64 provided on one side of the sealing plate body 63 and extending towards the adjacent sealing plate 6. The baffle portion 64 extends to the inner side of the sealing plate body 63, and the baffle portion 64 can abut against the busbar clamp assembly 3. The sealing plate body 63 has a third opening 65 on the side away from the baffle portion 64 for disassembling the sealing plate 6.

[0046] The present invention provides a hook-on adjustable phase fuse type disconnect switch, including a switch body 1, and a conductive busbar 2 and a busbar clamp assembly 3 disposed on the switch body 1. The busbar clamp assembly 3 can move along the length direction of the conductive busbar 2 and is suitable for clamping the incoming busbar. This setting of the busbar clamp assembly 3 allows for flexible position changes, so that customers can freely draw power according to their own needs, and this can greatly reduce production costs.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
