Description

Technical Field

[0001] This invention relates to the field of power connector technology, and more particularly to a bus clamp. Background Technology

[0002] A manifold clamp is a specialized connection tool used in the electrical field. Its core function is to enable temporary or auxiliary conductive connections between different conductive components. At the same time, it ensures the stability and safety of the connection through mechanical clamping, making it an important tool for achieving reliable conductive connections in electrical operations.

[0003] For example, Chinese patent CN222826792U discloses a busbar clamp, including a tubular conductive main conductor, a conductive seat slidably connected to the front end of the main body, and two symmetrically arranged jaws movably connected to the front of the main body. The front ends of the two jaws have gripping portions on opposite sides, forming a clamping area between the two gripping portions and the conductive seat capable of clamping the copper busbar. An adjusting screw is rotatably connected to the rear end of the conductive seat, and the adjusting screw is threadedly connected to the main body, allowing the conductive seat to move relative to the length of the main body, thereby changing the width of the clamping area. A rotary drive rod is rotatably connected inside the main body, and the rotary drive rod is coaxially inserted with the adjusting screw, with the inserted portion being non-circular, so that the rotary drive rod rotates synchronously with the adjusting screw. This improves the stability of the busbar clamp connection to the copper busbar and enhances operational convenience.

[0004] The patent has the following technical problems: the jaws and the main body are operated separately and independently, and the user needs to adjust the jaws and the main body separately during use, which increases the operation steps and complexity. Summary of the Invention

[0005] To address the aforementioned technical problem of complex operation, this invention provides a bus clamp that can drive the coordinated operation of all functional components of the bus clamp with a single operation, eliminating the need for separate control of clamping, conductive, and other structures, thus greatly simplifying the operation process.

[0006] The specific technical solution of the present invention is as follows: a manifold clamp, comprising a handle, a conductive component, a clamping component, and a linkage component;

[0007] The handle includes a drive mechanism;

[0008] The conductive component includes a conductive sleeve and a conductive head that is electrically connected to the clamped object. The driving mechanism is slidably connected to the conductive sleeve, and the conductive head is slidably sleeved inside the conductive sleeve.

[0009] The clamping assembly is connected to the driving mechanism so that when the driving mechanism slides along the conductive sleeve toward the clamping assembly, it drives the clamping assembly to clamp.

[0010] The conductive sleeve is provided with an opening at the connection position with the driving mechanism, and the conductive head is provided with a first groove. Both the opening and the first groove extend along the sliding direction of the driving mechanism, and their positions correspond to form a space for the installation of the linkage component.

[0011] One end of the linkage component extends into the port and connects to the drive mechanism, while the other end extends into the first groove and connects to the conductive head, so that the conductive head can be moved in the same direction by the drive mechanism sliding along the conductive sleeve.

[0012] In the aforementioned bus clamp, the drive mechanism slides forward along the conductive sleeve, and the clamping component performs a clamping action to achieve mechanical clamping of the object. Furthermore, when the drive mechanism slides along the conductive sleeve, the linkage component pushes the conductive head to slide in the same direction along the inner cavity of the conductive sleeve, with the front end of the conductive head contacting the surface of the object and making a conductive connection. Disconnection is achieved simply by moving the drive mechanism backward, releasing the clamping mechanism, and allowing the conductive head to move backward and separate from the surface of the object. This invention, by setting the drive mechanism to be connected to both the clamping component and the conductive component, achieves the following: when the clamping component clamps, the conductive component extends forward to make a conductive connection with the object; when the clamping component releases, the conductive component moves backward to disconnect from the object. Only a single operation is needed to drive the coordinated action of all functional components of the bus clamp, eliminating the need for separate operation of the clamping and conductive structures. This enables rapid connection and disconnection of the bus clamp with copper busbars and other objects, significantly simplifying the operation process.

[0013] Optionally, the linkage component includes a linkage block and an elastic element. One end of the linkage block extends into the through-hole and connects to the drive mechanism, and the other end extends into the first groove and connects to the conductive head. The elastic element is disposed in the first groove and provides a preload force to the linkage block in the opposite direction to the movement of the drive mechanism.

[0014] In the above technical solution, the elastic element is set in the first groove and provides a reverse preload force to the linkage block. When the drive mechanism is not subjected to external force, the elastic element pushes the drive mechanism to slide backward along the conductive sleeve. The connecting rod drives the clamping mechanism to rotate in the opposite direction around the connecting part to achieve release. The linkage block drives the conductive head to move backward along the inner cavity of the conductive sleeve, so as to separate it from the surface of the clamped object, thereby realizing the automatic reset of the functional components and simplifying the operation process.

[0015] Optionally, the driving mechanism includes a pusher portion connected to the clamping assembly. The pusher portion is provided with a second groove extending along the sliding direction of the driving mechanism. In the horizontal direction, the rear end of the second groove is further back than the rear end of the first groove. One end of the linkage block extends into the second groove and slides in connection with the second groove, so that when the driving mechanism slides along the conductive post and conductive sleeve, it first drives the clamping assembly to move and then drives the conductive head to move.

[0016] In the above technical solution, the sliding of the linkage block within the second groove provides a travel distance for the clamping action. During the initial sliding phase of the forward pushing part, the force is primarily transmitted to the clamping assembly, which pre-clamps the object, thus initially fixing it. Only after the linkage block slides to the limit position of the groove will the continued sliding of the forward pushing part drive the conductive head through the linkage assembly. Simultaneously, the clamping assembly further increases the clamping force under the same driving force, achieving synchronous completion of conductivity and final clamping. This design, through a single operation sequentially driving the dual structures, avoids interference between the conductive head extending too far and the clamping mechanism, ensuring that the movement strokes of the clamping mechanism and the conductive head are matched.

[0017] Optionally, when the linkage block is at the front limit position of the second groove, the rear end of the linkage block contacts the rear end of the first groove.

[0018] In the above technical solution, the positions of the first groove and the second groove are connected, which ensures that after the clamping assembly completes the pre-clamping, the conductive head can immediately enter the effective action range, and the conductive head will not be delayed or premature due to the misalignment of the groove.

[0019] Optionally, the handle further includes a fixed sleeve fitted over the conductive component. The fixed sleeve is fixed to the conductive sleeve. The driving mechanism includes a push part connected to the clamping component and a limiting sleeve located at the rear end of the push part and separately disposed from the push part. The limiting sleeve is rotatably fitted over the fixed sleeve. The fixed sleeve is provided with a limiting part corresponding to the limiting sleeve. The limiting sleeve is provided with a sliding groove on the side near the limiting part. The limiting sleeve is provided with a first thread at the end of the sliding groove away from the push part. The limiting part is provided with a second thread at the end of the sliding groove near the push part. A sliding gap is left between the first thread and the second thread.

[0020] In the above technical solution, the limiting sleeve and the front push part move forward together, the first thread and the second thread gradually approach each other, the sliding gap between them decreases until they abut each other, the limiting sleeve rotates relative to the fixed sleeve, and pushes the front push part forward. When the clamping component is in the clamping state and the conductive component is electrically connected to the clamped object, the rotation stops and the position of the front push part is locked to ensure that the connection between the manifold clamp and the clamped object is stable and does not loosen, thus improving the convenience and stability of operation.

[0021] Optionally, the clamping assembly includes a connecting rod, a connecting part, and a clamping mechanism. The tail end of the connecting rod is rotatably connected to the driving mechanism, and the front end is rotatably connected to the clamping mechanism. One end of the connecting part is fixedly connected to the conductive sleeve, and the other end is rotatably connected to the clamping mechanism, so that the clamping assembly can be driven to clamp when the driving mechanism slides along the conductive sleeve toward the clamping assembly.

[0022] In the above technical solution, the drive mechanism slides forward along the conductive sleeve, the connecting rod pushes the clamping mechanism to rotate around the connecting part, and the clamping mechanism performs a clamping action to achieve mechanical clamping of the clamped object.

[0023] Optionally, the clamping mechanism includes a first jaw and a second jaw arranged opposite to each other. The tail ends of the first jaw and the second jaw are each connected to the driving mechanism via a connecting rod. The connecting part is sleeved on the conductive sleeve. Two connecting ends are symmetrically provided on the connecting part. The two connecting ends are rotatably connected to the middle part of the first jaw and the middle part of the second jaw, respectively. A clamping space is formed between the first jaw and the second jaw. The conductive head is driven by the driving mechanism to electrically connect with the clamped object in the clamping space.

[0024] In the above technical solution, a first and second jaw are arranged opposite to each other and paired with a double linkage transmission. The symmetrical "encircling" clamping provides stable positioning for the clamped object and avoids unilateral force deviation. When the drive mechanism slides, the double linkage synchronously transmits the driving force. The two symmetrically arranged connecting ends of the connecting part serve as the rotation fulcrum of the double jaw, ensuring that the rotation trajectory of the double jaw is completely symmetrical when it is under force, thereby ensuring that the front end movement path is consistent and avoiding clamping deviation of the first and second jaws.

[0025] In the above technical solution, the two symmetrically arranged connecting ends of the connecting part serve as the rotation fulcrum of the double jaws, ensuring that the rotation trajectory of the double jaws is completely symmetrical when subjected to force, thereby ensuring that the front end movement path is consistent and avoiding clamping deviation caused by asymmetry of the fulcrum.

[0026] Optionally, the front end of the first jaw is provided with a first clamping part, and the front end of the second jaw is provided with a second clamping part. The end faces of the first clamping part and the second clamping part near the clamping space are serrated.

[0027] In the above technical solution, the serrated shape increases the friction between the first clamping part, the second clamping part and the clamped object. The protruding structure of the serration can be embedded into the surface of the clamped object under the action of clamping force, effectively preventing the clamped object from being displaced due to equipment vibration and external force pulling during use, ensuring the stability and reliability of the connection between the bus clamp and the copper busbar, and ensuring the normal operation of the electrical system.

[0028] Optionally, the conductive head may have a toothed structure or a spiked structure on the end face near the clamping space.

[0029] In the above technical solutions, the toothed or spiked structure can help increase the friction between the conductive head and the surface of the clamped object, ensuring contact stability. Moreover, this structure can break the oxide film that may exist on the surface of the clamped object, allowing the metal material of the conductive head to directly contact the body of the clamped object, reducing contact resistance and ensuring efficient power transmission.

[0030] Optionally, the side wall of the conductive head is provided with a watch strap finger groove, and a watch strap finger is installed in the watch strap finger groove, with the watch strap finger tightly fitting the conductive sleeve and the conductive head.

[0031] In the above technical solution, the watch strap contact fingers can improve the electrical connection performance between the conductive sleeve and the conductive head, bringing efficient and stable current transmission to the power system and effectively avoiding electrical connection failure between the sliding sleeve conductive head and the conductive sleeve.

[0032] Compared with the prior art, the present invention has at least the following advantages: By setting a driving mechanism that is connected to the clamping component and the conductive component respectively, the present invention realizes that when the clamping component clamps, the conductive component extends forward to connect with the clamped object, and when the clamping component is released, the conductive component moves backward to disconnect from the clamped object. Only a single operation is needed to drive the coordinated action of all functional components of the busbar clamp, without the need to separately operate the clamping, conductive and other structures. This enables the rapid connection and disconnection of the busbar clamp with the copper busbar and other clamped objects, greatly simplifying the operation process and improving work efficiency. In addition, the present invention, by setting a second groove, reserves the stroke for the clamping action, so that the starting point of the conductive head's stroke lags behind the clamping mechanism, avoiding interference between the conductive head extending too far and the clamping mechanism, and ensuring that the movement stroke of the clamping mechanism and the conductive head are matched.

[0040] The present invention will now be described through specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Variations and advantages that can be conceived by those skilled in the art without departing from the spirit and scope of the inventive concept are included in the present invention, and the scope of protection of the present invention is defined by the appended claims and any equivalents thereof.

[0041] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. Unless otherwise specified, the raw materials and equipment used in this invention are conventional in the art and can be obtained through conventional commercial means; unless otherwise specified, the methods used in this invention are conventional methods in the art.

[0042] In this application, terms such as “first” and “second” are used only to distinguish one entity or operation from another, and do not necessarily require or imply any actual quantity, hierarchy or order relationship between these entities or operations.

[0043] In the following embodiments, for ease of explanation, the direction from the clamping component to the handle is defined as front to back, the direction from the clamping component to the handle is defined as front to back, "front end" refers to the end closer to the clamping component, and "rear end" and "tail end" refer to the end farther away from the clamping component.

[0044] Example 1:

[0045] Reference Figures 1 to 6 As shown, the present invention provides a manifold clamp, including a handle 1, a conductive component 2, a clamping component 3, and a linkage component 4;

[0046] The handle 1 is made of insulating material and includes a drive mechanism 11 and a fixed sleeve 12 sleeved on the outside of the conductive component 2. The drive mechanism 11 can slide along the axial direction of the conductive component 2. The drive mechanism 11 is used to drive the clamping component 3 and the conductive component 2 to move, so that when the clamping component 3 is in the clamping state, the conductive component 2 is electrically connected to the clamped object.

[0047] The conductive component 2 includes a conductive sleeve 21 and a conductive head 22 that is electrically connected to the clamped object. The conductive head 22 is slidably sleeved in the conductive sleeve 21. The driving mechanism 11 is slidably connected to the conductive sleeve 21, and the fixed sleeve 12 is fixed to the conductive sleeve 21, that is, the driving mechanism 11 can slide relative to the fixed sleeve 12.

[0048] The clamping assembly 3 is made of insulating material and is connected to the drive mechanism 11 so that when the drive mechanism 11 slides along the conductive sleeve 21 toward the clamping assembly 3, it drives the clamping assembly 3 to clamp.

[0049] The conductive sleeve 21 is provided with an opening 211 at the connection position with the drive mechanism 11, and the conductive head 22 is provided with a first groove 221. Both the opening 211 and the first groove 221 extend along the sliding direction of the drive mechanism 11, and their positions correspond to form the placement space of the linkage component 4.

[0050] One end of the linkage component 4 extends into the through-hole 211 and connects to the drive mechanism 11, while the other end extends into the first groove 221 and connects to the conductive head 22, so that the conductive head 22 can be moved in the same direction by the drive mechanism 11 along the sliding of the conductive sleeve 21.

[0051] The drive mechanism 11 slides forward along the conductive sleeve 21, and the clamping component 3 performs a clamping action to achieve mechanical clamping of the object. When the drive mechanism 11 slides along the conductive sleeve 21, the linkage component 4 pushes the conductive head 22 to slide in the same direction along the inner cavity of the conductive sleeve 21, and the front end of the conductive head 22 contacts the surface of the object and makes conductive connection with it. Conversely, when the operator pulls the drive mechanism 11 back, the clamping component 3 is released, and the linkage component 4 drives the conductive head 22 to move backward and separate from the surface of the object.

[0052] This invention, by setting a drive mechanism 11 to be connected to the clamping component 3 and the conductive component 2 respectively, enables the conductive component 2 to extend forward and make conductive connection with the clamped object when the clamping component 3 clamps, and the conductive component 2 to move backward and disconnect from the clamped object when the clamping component 3 is released. Only a single operation is needed to drive the coordinated action of all functional components of the busbar clamp, without the need to operate the clamping, conductive and other structures separately, realizing the rapid connection and disconnection of the busbar clamp with copper busbars and other clamped objects, greatly simplifying the operation process.

[0053] The end of the fixed sleeve 12 away from the drive mechanism 11 is open to expose the conductive sleeve 21, through which the conductive sleeve 21 can be connected to external electrical components.

[0054] Linear sliding between the drive mechanism 11 and the fixed sleeve 12, and between the drive mechanism 11 and the conductive sleeve 21, can be achieved through a linear slider groove 18 structure. For example, the outer wall of the conductive sleeve 21 is provided with a groove 18 extending axially, and the drive mechanism 11 is provided with a matching slider that can slide along the groove 18. In this way, the drive mechanism 11 can slide linearly along the groove 18 of the conductive sleeve 21 via the slider. An appropriate fitting clearance is maintained between the groove 18 and the slider, and grease or a self-lubricating material (such as a PTFE coating) can be applied to reduce frictional resistance.

[0055] Please see Figure 1 and Figure 2In some embodiments, the clamping assembly 3 includes a connecting rod 32, a connecting part 31, and a clamping mechanism 33. The tail end of the connecting rod 32 is rotatably connected to the driving mechanism 11, and the front end is rotatably connected to the clamping mechanism 33. One end of the connecting part 31 is fixedly connected to the conductive sleeve 21, and the other end is rotatably connected to the clamping mechanism 33, so that the clamping assembly 3 can be driven to clamp when the driving mechanism 11 slides along the conductive sleeve 21 toward the clamping assembly 3.

[0056] Reference Figure 1 The arrow indicates the direction, the drive mechanism 11 slides forward along the conductive sleeve 21, the connecting rod 32 pushes the clamping mechanism 33 to rotate around the connecting part 31, the clamping mechanism 33 performs a clamping action, and realizes the mechanical clamping of the clamped object.

[0057] Please see Figure 1 and Figure 2 In some embodiments, the linkage component 4 includes a linkage block 41 and an elastic element 42. One end of the linkage block 41 extends into the through-hole 211 and connects to the drive mechanism 11, while the other end extends into the first groove 221 and connects to the conductive head 22. The elastic element 42 is disposed in the first groove 221, providing a preload force to the linkage block 41 in the opposite direction to the movement of the drive mechanism 11. When the drive mechanism 11 is not subjected to external force, the elastic element 42 pushes the drive mechanism 11 to slide backward along the conductive sleeve 21. The connecting rod 32 drives the clamping mechanism 33 to rotate in the opposite direction around the connecting part 31 to achieve release. The linkage block 41 drives the conductive head 22 to move backward along the inner cavity of the conductive sleeve 21, separating it from the surface of the clamped object, thereby realizing the automatic reset of the functional component and simplifying the operation process.

[0058] The first groove 221 has two opposing sidewalls: one near the clamping mechanism 33 (i.e., the front end direction), called the "near clamping mechanism 33 sidewall," and the other away from the clamping mechanism 33 (i.e., the rear end direction), called the "far clamping mechanism 33 sidewall." One end of the elastic element 42 is fixed to the near clamping mechanism 33 sidewall, and the other end is fixed to the side of the linkage block 41 facing the near clamping mechanism 33 sidewall. The first groove 221 is used to accommodate and guide the movement of the linkage block 41 and to provide installation space for the elastic element 42. The initial state is the state when no external force is applied, the elastic element 42 is in a naturally extended state, the linkage block 41 abuts against the far clamping mechanism 33 sidewall of the first groove 221, the entire device is in a ready state, and the clamping mechanism 33 is opened to its maximum angle to facilitate clamping the object. It should be noted that this application does not limit the specific type of elastic element 42. Whether it is a metal coil spring, an elastic rubber column, or other elastic structure with elastic reset or force transmission functions, as long as it is an existing elastic structure that can achieve the above functions, it falls within the protection scope of this application.

[0059] When the operator pushes the drive mechanism 11 forward, the clamping mechanism 33 clamps and the conductive head 22 extends forward only when the operator's pushing force overcomes the preload of the elastic element 42. If the conductive head 22 contacts the copper busbar prematurely, the linkage block 41 will slide relative to the first groove 221 of the conductive head 22 when the operator continues to push the drive mechanism 11, further compressing the elastic element 42 until the clamping mechanism 33 fully clamps the object. Conversely, if the clamping mechanism 33 contacts and clamps the copper busbar before the conductive head 22, and the conductive head 22 is not yet connected to the copper busbar, when the operator stops pushing the drive mechanism 11 and fixes its position, the compressed elastic element 42 will release its stored elastic potential energy, applying a pushing force towards the clamping mechanism 33, pushing the conductive head 22 to continue sliding forward relative to the conductive sleeve 21 until its front end reliably contacts the surface of the copper busbar, completing the electrical connection. By arranging the elastic element 42 between the linkage block 41 and the front end of the conductive head 22, the compensation between clamping and conduction is cleverly achieved.

[0060] Furthermore, the drive mechanism 11 includes a pusher 16 connected to the tail end of the connecting rod 32. The pusher 16 is provided with a second groove 14 extending along the sliding direction of the drive mechanism 11. In the horizontal direction, the rear end of the second groove 14 is further back than the rear end of the first groove 221. One end of the linkage block 41 extends into the second groove 14 and is slidably connected to the second groove 14. That is, the linkage block 41 can move relative to the drive mechanism 11 in the sliding direction of the second groove 14, rather than being fixed, so that when the drive mechanism 11 slides along the conductive sleeve 21, it first drives the clamping assembly 3 to move and then drives the conductive head 22 to move. The sliding of the linkage block 41 within the second groove 14 provides travel space for the clamping action. In the initial sliding phase of the pusher 16, the force is primarily transmitted to the clamping assembly 3 via the connecting rod 32. The clamping assembly 3 pre-clamps the object, initially fixing it in place. Only after the linkage block 41 slides to the limit position of the groove will the continued sliding of the pusher 16 drive the conductive head 22 to move via the linkage assembly 4. Simultaneously, the clamping assembly 3 further increases the clamping force under the same driving force, achieving synchronous completion of conductivity and final clamping. This design, through a single operation sequentially driving the dual structures, avoids excessive extension of the conductive head 22 and interference with the clamping mechanism 33, ensuring that the movement strokes of the clamping mechanism 33 and the conductive head 22 are matched.

[0061] It should be noted that this application does not impose any restrictions on the specific lengths of the first groove 221 and the second groove 14. The lengths of the second groove 14 and the first groove 221 should follow these guidelines: the length of the second groove 14 should be slightly greater than the effective stroke of the linkage 32 driving the clamping mechanism 33 to complete the "release-clamp" action, to ensure the complete realization of the clamping function; the length of the first groove 221 should not be less than the sum of the stroke of the linkage block 41 driving the conductive component 2 to complete the "disconnect-connect" action and the deformation stroke of the elastic element 42, to ensure the conductivity function and reset reliability; at the same time, the length of the second groove 14 should be less than the effective working stroke of the first groove 221, so as to structurally lock the action sequence of "the conductive component 2 acting after the clamping mechanism 33" through the length difference, and avoid action conflicts or functional failures caused by stroke mismatch.

[0062] Furthermore, when the linkage block 41 is at the front limit position of the second groove 14, the rear end of the linkage block 41 contacts the rear end of the first groove 221. The positions of the first groove 221 and the second groove 14 are connected, ensuring that after the clamping assembly 3 completes the pre-clamping, the conductive head 22 can immediately enter the effective operating range, and the conductive head 22 will not be delayed or premature due to groove misalignment.

[0063] Please see Figure 1 and Figure 2 In some embodiments, the drive mechanism 11 includes a pusher 16 connected to the tail end of the connecting rod 32 and a limiting sleeve 13 disposed at the rear end of the pusher 16 and separately disposed from the pusher 16. The limiting sleeve 13 is rotatably sleeved on the fixed sleeve 12. The fixed sleeve 12 is provided with a limiting part 17 corresponding to the limiting sleeve 13. The limiting sleeve 13 is provided with a groove 18 on the side near the limiting part 17. The limiting sleeve 13 is provided with a first thread at the end of the groove 18 away from the pusher 16. The limiting part 17 is provided with a second thread adapted to the first thread at the end of the groove 18 near the pusher 16. A sliding gap 15 is left between the first thread and the second thread. The limiting sleeve 13 moves forward together with the front push part 16. The first thread and the second thread gradually approach each other, and the sliding gap 15 between them decreases until they abut each other. The limiting sleeve 13 rotates relative to the fixed sleeve 12, pushing the front push part 16 forward. When the clamping assembly 3 is in the clamping state and the conductive assembly 2 is electrically connected to the clamped object, the rotation stops, and the position of the front push part 16 is locked to ensure that the connection between the manifold clamp and the clamped object is stable and does not loosen, thus improving the convenience and stability of operation. It can be understood that the extension direction of the slide groove 18 can be flexibly set. It can extend from the front end near the front push part 16 to the rear end, or it can extend from the rear end away from the front push part 16 to the front end, as long as the limiting part 17 can form an effective limit within the slide groove 18 when the limiting sleeve 13 slides with the front push part 16.

[0064] In the embodiment where the second groove 14 is provided, the length of the sliding gap 15 is greater than the length of the second groove 14. This ensures that when the push part 16 drives the linkage block 41 to complete the full stroke of the drive clamping mechanism 33 "releasing-clamping" along the second groove 14, the first thread and the second thread are still not engaged. This avoids the thread engagement interfering with the clamping action in advance. After the clamping mechanism 33 completes the clamping, the push part 16 continues to slide so that the sliding gap 15 gradually decreases until the first thread and the second thread engage. At this time, rotating the limiting sleeve 13 can lock the position of the push part 16.

[0065] like Figures 4 to 6 As shown, in the initial state, the front end of the linkage block 41 contacts the front end of the second groove 14, and the rear end contacts the rear end of the first groove 221. The first thread of the limiting sleeve 13 is separated from the second thread of the limiting part 17, and the maximum sliding gap 15 is maintained between them. Then, the forward pushing part 16 and the limiting sleeve 13 slide forward together under the pushing force until the rear end of the linkage block 41 contacts the rear end of the second groove 14. The first thread of the limiting sleeve 13 and the second thread of the limiting part 17 gradually approach each other, and the sliding gap 15 between them decreases. The connecting rod 32 slides with the forward pushing part 16 to push the clamping mechanism 33 to rotate around the connecting part 31. The three pairs are pre-clamped, at which point the manifold is in a pre-clamped state. Then, the push part 16 and the limiting sleeve 13 continue to slide forward together under the pushing force. The linkage component 4 drives the conductive head 22 to move forward. At the same time, the clamping component 3 further increases the clamping force under the same driving force. The sliding gap 15 between the first thread and the second thread is reduced until the two abut against each other. The limiting sleeve 13 rotates relative to the fixed sleeve 12, pushing the push part 16 forward until the manifold is in the final clamped state. At this time, the conduction and final clamping are completed simultaneously. Under the threaded connection of the limiting sleeve 13 and the limiting part 17, the position of the push part 16 is locked to ensure the continuity of the connection.

[0066] Please see Figure 1In some embodiments, the clamping mechanism 33 includes a first jaw and a second jaw arranged opposite to each other. The tail ends of the first jaw and the second jaw are each connected to the driving mechanism 11 via a connecting rod 32. The connecting part 31 is sleeved on the conductive sleeve 21, and two connecting ends are symmetrically arranged on the connecting part 31. The two connecting ends are rotatably connected to the middle of the first jaw and the middle of the second jaw, respectively. A clamping space 6 is formed between the first jaw and the second jaw. The conductive head 22 is driven by the driving mechanism 11 to electrically connect with the clamped object in the clamping space 6. By using the first jaw and the second jaw arranged opposite to each other and combined with the double connecting rod transmission, the symmetrical "encircling" clamping provides stable positioning for the clamped object and avoids unilateral force deviation. When the driving mechanism 11 slides, the double connecting rod synchronously transmits the driving force. The two symmetrically arranged connecting ends of the connecting part 31 serve as the rotation fulcrum of the double jaw, ensuring that the rotation trajectory of the double jaw is completely symmetrical when it is under force, thereby ensuring that the front end movement path is consistent and avoiding clamping deviation of the first jaw and the second jaw.

[0067] Furthermore, the front end of the first jaw is provided with a first clamping part, and the front end of the second jaw is provided with a second clamping part. The end faces of the first and second clamping parts near the clamping space 6 are serrated. The serration increases the friction between the first and second clamping parts and the clamped object. In reality, the surface of the clamped object may have certain roughness differences, or slight oil stains, oxide layers, etc. The serrated protrusions can embed into the surface of the clamped object under the action of clamping force, effectively preventing the clamped object from being displaced due to equipment vibration or external pulling during use, ensuring the stability and reliability of the connection between the bus clamp and the copper busbar, and ensuring the normal operation of the electrical system.

[0068] The conductive head 22 has a toothed or spiked structure on its end face near the clamping space 6. The toothed or spiked structure can increase the friction between the conductive head 22 and the surface of the object being held, ensuring contact stability. In addition, this structure can break the oxide film that may exist on the surface of the object being held, allowing the metal material of the conductive head 22 to directly contact the object body, reducing contact resistance and ensuring efficient power transmission.

[0069] Please see Figure 1 In some embodiments, the sidewall of the conductive head 22 is provided with a watchband finger groove 5, and a watchband finger is installed in the watchband finger groove 5. The watchband finger fits tightly against the conductive sleeve 21 and the conductive head 22. The watchband finger can improve the electrical connection performance between the conductive sleeve 21 and the conductive head 22, bringing efficient and stable current transmission to the power system, and effectively avoiding electrical connection failure between the slidingly connected conductive head 22 and the conductive sleeve 21.

[0070] Please see Figure 1 and Figure 3In some embodiments, the conductive head 22 has a T-shaped cross-section. The head of the conductive head 22 extends outside the conductive sleeve 21, and the tail of the conductive sleeve 21 may be rod-shaped. Inside the conductive sleeve 21, a first groove 221 is provided. The head area of ​​the conductive head 22 is larger than the tail area, which can provide a larger contact area with the clamped object and is conducive to establishing a more stable power transmission.

[0072] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any simple modifications, alterations, and equivalent transformations made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
