Description

Technical Field

[0001] This invention relates to the field of disconnecting switch technology, and specifically to an adjustable fuse-type disconnecting switch. Background Technology

[0002] Fuse-type disconnect switches are important switching devices in low-voltage power distribution systems. Their main functions are: to be used as power switches, disconnect switches or emergency switches in power distribution circuits and motor circuits with high short-circuit currents, and to protect AC circuits.

[0003] Current fuse-type disconnect switches include a housing, with multiple busbar clamps at the bottom of the housing for holding the incoming busbars. The height of these busbar clamps is fixed, preventing them from moving flexibly and thus preventing customers from freely drawing power according to their needs. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the bus clamp in the prior art cannot be moved, thereby providing an adjustable fuse-type disconnect switch with a bus clamp that can be moved.

[0005] Therefore, the present invention provides an adjustable fuse-type disconnect switch, including a switch body, and a conductive busbar and a busbar clamp assembly disposed on the switch body. The busbar clamp assembly is movable along the length direction of the conductive busbar and is adapted to clamp the incoming busbar. A positioning structure is provided between the busbar clamp assembly and the conductive busbar.

[0006] The busbar clamp assembly includes a busbar clamp and a sleeve fitted onto the busbar clamp. The sleeve contains a conductive block suitable for connecting the incoming busbar and the conductive busbar. The positioning structure includes at least one positioning feeder and positioning block assembly. At least one positioning groove is provided on the conductive busbar. The positioning block assembly is located between the conductive block and the conductive busbar and can be adapted to connect with the positioning groove.

[0007] The positioning block assembly includes a positioning block disposed on the top of the conductive block, and an elastic member disposed inside the conductive block for attaching and abutting the positioning block against the conductive busbar.

[0008] The positioning block is a ball bearing, and the diameter of the ball bearing is larger than the opening diameter of the positioning groove.

[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 conductive block is fixedly installed on the sleeve by a plug-in structure. The plug-in structure includes a first plug, a second plug, a first opening, and a second opening. The first plug and the second plug are respectively located on both sides of the conductive block along its length. The first opening and the second opening are respectively plugged into the first plug and the second plug.

[0011] The bottom surface of the switch body is detachably equipped with multiple sealing plates for shielding the conductive busbar.

[0012] 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.

[0013] The sealing plate includes a sealing plate body, and a first extension and a second extension respectively disposed on both sides of the sealing plate body. The first extension extends to the outside of the adjacent second extension. The sealing plate is provided with a third opening for disassembling the sealing plate on one side of the first extension, which is abutting against the busbar clamp assembly.

[0014] A limiting structure for controlling the distance between two adjacent sealing plates is provided between two adjacent sealing plate bodies. The limiting structure includes a limiting block provided on the first extension and a plurality of limiting grooves provided on the second extension that can be adapted and connected to the limiting block. The limiting grooves extend along the width direction of the second extension and the plurality of limiting grooves are spaced apart along the length direction of the second extension.

[0015] The technical solution of this invention has the following advantages:

[0016] 1. The adjustable fuse-type disconnect switch provided by the present invention includes a switch body, and a conductive busbar and a busbar clamp assembly disposed on the switch body. The busbar clamp assembly can move along the length direction of the conductive busbar and is suitable for clamping the incoming busbar. A positioning structure is provided between the busbar clamp assembly and the conductive busbar. This setting allows the busbar clamp assembly to flexibly change position, so that customers can freely draw power according to their own needs. This can also greatly reduce production costs. The positioning structure can facilitate the movement of the busbar clamp assembly to the accurate position, making adjustment faster and more convenient.

[0017] 2. The adjustable fuse-type disconnect switch provided by the present invention includes a positioning block assembly comprising a positioning block disposed on the top of a conductive block and an elastic member disposed inside the conductive block for fitting and abutting the positioning block against the conductive busbar. This arrangement allows the positioning block to be inserted into and removed from the positioning groove, facilitating the movement of the busbar clamp assembly. Furthermore, the positioning block assembly has the advantage of simple structure.

[0018] 3. The adjustable fuse-type disconnect switch provided by the present invention has a ball bearing as the positioning block. The height of the ball bearing inserted into the positioning groove is one-third of the diameter of the ball bearing. With this setting, only a certain force needs to be applied to the bus clamp assembly to make the ball bearing disengage from the positioning groove, which makes the movement of the bus clamp assembly faster and more convenient.

[0019] 4. The adjustable fuse-type disconnect switch provided by the present invention has a jacket with a first opening and a second opening respectively disposed on both sides of its length direction, through which a conductive busbar can pass. During assembly, the conductive busbar is inserted sequentially along the first opening and the second opening of the jacket, so that the jacket can be moved along the length direction of the conductive busbar. This makes adjustment faster and more convenient, and the jacket is not easily separated from the conductive busbar.

[0020] 5. The adjustable fuse-type disconnect switch provided by the present invention includes a switch body and a plug-in structure including a first plug, a second plug, a first opening, and a second opening. The first plug and the second plug are respectively disposed on both sides of the conductive block along its length. The first opening and the second opening are respectively plugged into the first plug and the second plug. The plug-in structure allows the conductive block to be fixedly installed on the jacket, and the adapted connection of the first plug, the second plug, the first opening, and the second opening has the advantage of simple structure.

[0021] 6. The adjustable fuse-type disconnect switch provided by the present invention includes a switch body, and a sealing plate is fixedly installed on the conductive busbar by an elastic hook structure. The elastic hook structure includes an elastic arm provided on the top surface of the sealing plate, and a hook provided on the elastic arm that can abut against the top surface of the conductive busbar. The elastic hook structure facilitates the installation of the sealing plate on the conductive busbar, making the installation faster and more convenient.

[0022] 7. The adjustable fuse-type disconnect switch provided by the present invention includes a sealing plate body, and a first extension and a second extension respectively disposed on both sides of the sealing plate body. The first extension extends to the outside of the adjacent second extension. The sealing plate can abut against the busbar assembly. A third opening for disassembling the sealing plate is provided on one side of the first extension. This arrangement can increase the electrical clearance and improve the safety factor. In addition, the baffle portion of the sealing plate can abut against the busbar clamp assembly, which can play a positioning role for the busbar clamp assembly.

[0023] 8. The adjustable fuse-type disconnect switch provided by the present invention has a limiting structure between two adjacent sealing plates for controlling the distance between the two adjacent sealing plate bodies. The limiting structure includes a limiting block on a first extension and multiple limiting grooves on a second extension that can be adapted to and connected with the limiting block. The limiting grooves extend along the width direction of the second extension, and the multiple limiting grooves are spaced apart along the length direction of the second extension. By adjusting the position of the limiting block in different limiting grooves, the distance between the two adjacent sealing plate bodies can be adjusted, and the positions of the two adjacent sealing plates will not move relative to each other after assembly. This configuration allows the sealing plates to be used on fuse-type disconnect switches of different specifications, expands the application range of the sealing plates, and greatly reduces production costs.
