Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a portable multi-functional bus clamp. Background Technology

[0002] With the increasing frequency of use of various work vehicles such as transformer substations and generator trucks, busbar clamps are often used to achieve safe and rapid power connection. To accommodate cables and busbars of different sizes, existing busbar clamps often have adjustment mechanisms to adjust the clamping opening size. For example, CN114709644B discloses an adjustable busbar clamp with an external thread at the front end of its rotating shaft and a threaded hole on the moving block that meshes with the rotating shaft. Rotating the rotating shaft drives the movable clamp plate to move towards the front fixed clamp head to clamp the cable or busbar. However, during operation, if the rotating shaft is accidentally triggered to rotate, causing the movable clamp plate to move away from the front fixed clamp head, the cable or busbar may detach from between the movable clamp plate and the fixed clamp head, making the operation unreliable. Utility Model Content

The movable clamping block is slidably connected in the movable groove and forms a clamping space together with the upper wall of the movable groove. The insulating shell is connected to the outside of the fixed clamping block.

[0007] The operating handle includes a conductive rod and an insulating handle. The insulating handle is connected to the outside of the conductive rod.

[0034] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. The various technical features of this utility model can be combined interactively without contradicting each other.

[0035] Reference Figures 1 to 6 This utility model embodiment proposes a portable multi-functional bus clamp that can be operated on overhead cables and on busbars in switch cabinets. It is compact, lightweight, easy to operate, safe and reliable, applicable to a wider range of scenarios, and economical and practical.

[0036] In this embodiment, the portable multi-functional bus clamp includes a clamping structure 100, an operating handle 200, and a locking structure 300. For ease of description, the portable multi-functional bus clamp is placed vertically, with the operating handle 200 extending in the vertical direction and the clamping structure 100 positioned above the operating handle 200. It is understood that in actual use, the direction of the portable multi-functional bus clamp can be adjusted according to actual needs. For example, when applied in a switch cabinet, the clamping structure 100 can be used to clamp the busbar located inside the switch cabinet, while the operating handle 200 extends out of the switch cabinet.

[0037] The clamping structure 100 is used to clamp cables or busbars, and includes a movable clamping block 110, a fixed clamping block 120, and an insulating shell 130. The fixed clamping block 120 is provided with a movable groove 140 and a threaded hole. The upper end of the movable groove 140 communicates with the threaded hole. The movable clamping block 110 is slidably connected in the movable groove 140, and together with the upper wall of the movable groove 140, forms a clamping space 150. The insulating shell 130 is connected to the outside of the fixed clamping block 120, and can be made of insulating materials such as plastic, providing insulation.

[0038] The operating handle 200 includes a conductive rod 210 and an insulating handle 220. The insulating handle 220 is connected to the outside of the conductive rod 210 and can be made of insulating materials such as plastic. The upper end of the conductive rod 210 extends into the movable slot 140 through a threaded hole and is rotatably connected to the movable clamping block 110. The conductive rod 210 is threadedly connected to the wall of the threaded hole. When the operator rotates the insulating handle 220, the conductive rod 210 rotates with it. Under the action of the thread, the movable clamping block 110 moves up and down along the conductive rod 210 to move closer to or further away from the upper wall of the movable slot 140, thereby reducing or increasing the clamping space 150 to accommodate cables or busbars of different sizes.

[0039] Understandably, the movable clamping block 110 is restricted by the movable groove 140 to slide up and down but cannot rotate with the conductive rod 210. In some embodiments, the side wall of the movable groove 140 is provided with a slide rail extending up and down, and the side of the movable clamping block 110 is provided with a guide groove. The slide rail is engaged in the guide groove. Under the mutual restriction of the guide groove and the slide rail, the movable clamping block 110 cannot rotate.

[0040] It is worth noting that this embodiment also includes a locking structure 300, which can lock the rotation of the conductive rod 210, thus playing a safety role and keeping the size of the clamping space 150 unchanged during the clamping operation, thereby ensuring the stability of the clamping.

[0041] In this embodiment, refer to Figure 5 The locking structure 300 includes a gear 310, a stop block 320, and an operating component. The gear 310 is sleeved on the outer periphery of the conductive rod 210. The stop block 320 is provided with a toothed segment. The operating component is drivenly connected to the stop block 320. Under the driving action of the operating component, the stop block 320 can move relative to the gear 310, so that the toothed segment can mesh with or separate from the gear 310. Figure 5 The text indicates the unlocked status.

[0042] When the toothed segment meshes with the gear 310, the rotation of the conductive rod 210 is restricted, so that the clamping space 150 is kept in a suitable size; when the toothed segment separates from the gear 310, the conductive rod 210 can rotate freely, thereby adjusting the clamping space 150.

[0043] Understandably, to ensure synchronous rotation of the gear 310 and the conductive rod 210, the conductive rod 210 is non-circular at the position where the gear 310 is mounted, and the gear 310 has mounting holes corresponding to the shape of the mounting position of the conductive rod 210. Understandably, the gear 310 has a certain thickness in the vertical direction, which is greater than the length of the movable clamping block 110 that can move vertically. After the conductive rod 210 moves vertically relative to the fixed clamping block 120, when the operating component drives the abutment 320 to the locked state, the toothed segments can all mesh with the gear 310.

[0044] In some embodiments, a gasket groove is provided on the outer periphery of the conductive rod 210. The gasket groove is located above the mounting position of the gear 310 and is used to install a gasket. After installation, the gasket contacts the upper surface of the gear 310, which can prevent the connection between the gear 310 and the conductive rod 210 from becoming loose.

[0045] In some embodiments, the fixing block 120 is also provided with a locking groove, which is connected to the lower end of the threaded hole, providing installation space for the locking structure 300, and the abutment 320 of the gear 310 is provided in the locking groove.

[0046] In some embodiments, the operating component includes a cam 340, a rotating handle 330, and a return spring 350. One end of the rotating handle 330 is connected to the cam 340, and the other end passes through the side wall of the locking groove and extends to the outside of the insulating housing 130 to facilitate operation by the operator. A rotating shaft is provided in the locking groove, extending vertically. A stop block 320 is rotatably connected to the rotating shaft. One side of the stop block 320 abuts against the cam 340, and the other side abuts against the return spring 350. The return spring 350 is connected to the side wall of the locking groove.

[0047] In this embodiment, the rotating handle 330 is arranged perpendicular to the central axis of the conductive rod 210. Under the action of the return spring 350, the abutment 320 remains in contact with the side wall of the cam 340. When the rotating handle 330 is rotated, the cam 340 rotates, and the abutment 320 can rotate around the rotating shaft with the rotation of the cam 340, thereby realizing contact or separation with the gear 310.

[0048] In some embodiments, the operating component further includes an insulating handle 360, which is disposed on the outside of the rotating handle 330 and may be made of insulating material such as plastic. Limiting protrusions 131 are provided on the outside of the insulating shell 130, and the insulating handle 360 ​​can swing between two limiting protrusions 131. The operator can rotate the rotating handle 330 by manipulating the insulating handle 360 ​​to lock or unlock the conductive rod 210. When the insulating handle 360 ​​abuts against one of the limiting protrusions 131, the toothed segment on the abutment 320 meshes with the gear 310, locking the conductive rod 210; when the insulating handle 360 ​​abuts against the other limiting protrusion 131, the toothed segment on the abutment 320 completely disengages from the gear 310, unlocking the conductive rod 210.

[0049] In this embodiment, one limiting protrusion 131 is disposed on the upper side of the rotating handle 330. When the insulating handle 360 ​​abuts against the limiting protrusion 131, the toothed segment separates from the gear 310, and the conductive rod 210 is unlocked. The other limiting protrusion 131 is disposed on the lower side of the rotating handle 330. When the insulating handle 360 ​​abuts against the limiting protrusion 131, the toothed segment separates from the gear 310.

[0050] In this embodiment, the outer side of the insulating shell 130 is provided with locking and unlocking indicators. The indicators are located on the side of the corresponding limiting protrusion 131 and outside the swing range of the insulating handle 360. The operator can intuitively know the current status of the conductive rod 210 and take corresponding actions.

[0051] In some embodiments, the operating components further include a limiting ball 362 and a limiting spring 361. The insulating handle 360 ​​is provided with a mounting groove opening toward the insulating shell 130. The limiting spring 361 is disposed in the mounting groove, and one end of the limiting spring 361 near the insulating shell 130 is connected to the limiting ball 362. In this embodiment, the limiting ball 362 can retract or protrude from the mounting groove. Two limiting grooves are provided on the outer side of the insulating shell 130. The positions of the two limiting grooves correspond to the positions of the limiting ball 362 when the insulating handle 360 ​​abuts against the two limiting protrusions 131, and the limiting grooves and the limiting ball 362 cooperate with each other.

[0052] It is understood that the two limiting grooves are located within the swing range of the insulating handle 360. In this embodiment, when the insulating handle 360 ​​swings to the position of locking or unlocking the conductive rod 210, the limiting ball 362 enters the corresponding limiting groove under the drive of the limiting spring 361. Under the limiting effect of the limiting ball 362 and the limiting groove, the insulating handle 360 ​​is less likely to swing automatically, further improving the reliability of the portable multi-functional bus clamp. When the insulating handle 360 ​​has not fully swung to the position of locking or unlocking the conductive rod 210, the limiting ball 362 abuts against the outer wall of the insulating shell 130, the limiting spring 361 is in a compressed state, and the limiting ball 362 will not interfere with the swing of the insulating handle 360.

[0053] In some embodiments, a connecting block 211 is provided at the upper end of the conductive rod 210, and a connecting groove is provided on the lower wall of the movable clamping block 110. The connecting groove extends to an opening on the side wall of the movable clamping block 110. The connecting block 211 can enter the connecting groove through the opening and engage with the groove wall to achieve a rotatable connection between the conductive rod 210 and the movable clamping block 110. This configuration facilitates the installation and connection of the conductive rod 210 and the movable clamping block 110.

[0054] In some embodiments, the lower wall of the movable groove 140 is provided with at least one sliding groove 170, which extends in the vertical direction. The clamping structure 100 also includes at least one limiting rod 160, which extends in the vertical direction and whose lower end extends into the sliding groove 170. In this embodiment, there are two sliding grooves 170 and two corresponding limiting rods 160. The upper end of one limiting rod 160 is threadedly connected to the movable clamping block 110, and the lower end of the limiting rod 160 is slidably connected to the groove wall of the sliding groove 170. When the movable clamping block 110 moves vertically relative to the fixed clamping block 120, the limiting rod 160 moves vertically along the groove wall of the sliding groove 170. The upper end of another limiting rod 160 passes through the movable clamping block 110 and is threadedly connected to the upper wall of the clamping space 150. When the movable clamping block 110 moves up and down relative to the fixed clamping block 120, the movable clamping block 110 moves up and down along the limiting rod 160.

[0055] Understandably, the setting of the limiting rod 160 can lock the position of the movable clamping block 110 and the fixed clamping block 120 in the horizontal direction, restrict the position between the movable clamping block 110 and the conductive rod 210, and prevent the connecting block 211 from sliding relative to the connecting groove during the clamping process, thereby further improving the reliability of the portable multi-functional bus clamp.

[0056] In some embodiments, the upper and lower walls of the clamping space 150 are respectively provided with cable grooves with opposite openings. The cable grooves are arc-shaped and the groove walls are provided with anti-slip teeth, which can facilitate the clamping of cables and increase the contact area between the inner wall of the clamping space 150 and the cable, so as to ensure the current carrying capacity of the portable multi-functional bus clamp.

[0057] In addition, the upper and lower walls of the clamping space 150 are respectively provided with busbar grooves with opposite openings. The busbar grooves can increase the contact area between the inner wall of the clamping space 150 and the busbar to ensure its current carrying capacity. In some embodiments, the busbar grooves are provided with piercing blades that can pierce the insulation layer on the outer surface of the busbar.

[0058] It is understood that this embodiment is equipped with both cable troughs and busbar troughs, which can be used for live operation on overhead cables as well as live operation on busbars in switch cabinets, making it highly versatile.

[0059] In some embodiments, the lower end of the conductive rod 210 is provided with a power receiving groove 212, which opens downwards and is used to connect to a peripheral plug. The inner wall of the power receiving groove 212 is provided with a locking slot that engages with the outer wall of the plug's conductive pins to lock the plug in place. When connecting the plug, the conductive pins of the plug are inserted into the power receiving groove 212 through the lower opening and locked in place by the locking slot. This prevents the plug pins from easily dislodging from the power receiving groove 212, facilitating the connection operation and ensuring operational reliability.

[0060] It is understandable that after the plug is connected to the conductive rod 210, the cable or busbar clamped in the clamping space 150 can achieve a conductive connection with the plug through the fixed clamp 120, the movable clamp 110 and the conductive rod 210.

[0061] In some embodiments, the outer wall of the insulating handle 220 is provided with an indicator for plug locking or unlocking to facilitate operation by the operator.

[0062] In some examples, the insulating handle 220 includes a handle body 221 and an end cap 222. The handle body 221 has a mounting cavity, and the lower end of the mounting cavity has a connection port. The end cap 222 is movably connected to the lower end of the handle body 221, allowing the connection port to be opened or closed. When plugging in power is required, the end cap 222 is opened, exposing the mounting cavity and the internal power receiving groove 212, allowing the plug to be easily inserted. When not in use, the end cap 222 closes the connection port, protecting the conductive rod 210 inside the mounting cavity.

[0063] In some embodiments, the end cap 222 is connected to the handle 221 by a flexible strap. When the end cap 222 opens the connection port, the end cap 222 remains connected to the handle 221 to prevent the end cap 222 from being lost.

[0064] It is understandable that, in order to ensure the safety of the plug, a protective shell is provided on the outside of the conductive pin of the plug. The protective shell is made of insulating material. In this embodiment, there is a gap between the lower inner wall of the mounting cavity and the lower outer wall of the conductive rod 210, which can provide an insertion space for the protective shell and avoid interference between the protective shell and the insulating handle 220 during the plug connection process.

[0065] In some embodiments, the outer periphery of the middle portion of the conductive rod 210 is detachably connected to the mounting cavity. To ensure synchronous rotation of the conductive rod 210 and the insulating handle 220, the middle portion of the conductive rod 210 at the position for connecting the insulating handle 220 is non-circular. A connecting step 223 is provided at the corresponding position on the inner wall of the mounting cavity. The connecting step 223 has a groove, the shape of which matches the shape of the position on the conductive rod 210 where it connects to the insulating handle 220. To facilitate the installation of the conductive rod 210, in this embodiment, the diameter of the upper section of the conductive rod 210 at the position for connecting the insulating handle 220 is smaller than the minimum width of the groove provided in the mounting cavity to match the conductive rod 210. The conductive rod 210 can be inserted into the mounting cavity from the lower end upwards and achieve connection with the insulating shell 130.

[0066] In this embodiment, a locking block is provided at the lower end of the connecting step 223, and a locking slot is provided on the outer periphery of the conductive rod 210. When the conductive rod 210 is installed in the preset position in the mounting cavity, the locking block can be locked into the locking slot to realize the connection between the conductive rod 210 and the insulating handle 220.

[0067] It is understood that the space below the connecting step 223 is the insertion space for inserting the protective shell. In this embodiment, a sealing ring is provided at the upper end of the insertion space. It is understood that the depth of the insertion space in the vertical direction should be greater than or equal to the distance between the upper end of the plug protective shell and the connection port when the conductive rod 210 moves upward to the highest position and is connected to the plug.

[0068] In some embodiments, the outer periphery of the insulating handle 220 is provided with anti-slip grooves 224. The anti-slip grooves 224 can increase the friction between the insulating handle 220 and the operator's hand, making it easier for the operator to rotate the insulating handle 220, thereby controlling the adjustment of the size of the clamping space 150. In this embodiment, three anti-slip grooves 224 are provided, and the three anti-slip grooves 224 are arranged in a vertical direction.

[0069] In some embodiments, the insulating shell 130 includes an upper shell and a lower shell, which are detachably connected to facilitate the installation of the internal structure of the insulating shell 130. The lower shell covers the outer side of the lower portion of the fixing block 120, and the upper shell covers the outer side of the upper portion of the fixing block 120. The upper shell is provided with a cable passage, which communicates with the movable groove 140 to facilitate the insertion of cables and busbars into the clamping space 150.

[0070] In this embodiment, the lower end of the upper shell and the upper end of the lower shell are detachably connected by a snap fastener. The lower end of the lower shell extends downward into the interior of the insulating handle 220, ensuring that no conductive material is exposed at the connection between the insulating handle 220 and the insulating shell 130, preventing accidental contact by the operator, and further ensuring the safety of live operation.

[0071] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
