Its core function is to realize temporary or auxiliary conductive connection between different conductive components, and at the same time, to ensure the stability and safety of the connection through mechanical clamping. It is an important tool for realizing reliable conductive connection in electrical operation.

[0003] For example, a bus bar clamp is disclosed in Chinese Patent No. CN222826792U, which includes a tubular main conductor made of conductive material, a conductive seat slidingly connected to the front end of the main conductor, and two symmetrical clamping jaws movably connected to the front part of the main conductor. The front end of each clamping jaw is provided with a gripping portion on the side facing each other, and the gripping portions and the conductive seat form a clamping interval capable of clamping the copper bar. The rear end of the conductive seat is rotatably connected to an adjusting screw, which is threadedly connected to the main conductor, so that the conductive seat can move relative to the length direction of the main conductor, thereby changing the width of the clamping interval. A rotary drive rod is rotatably connected to the main conductor, and the rotary drive rod and the adjusting screw are coaxially inserted and connected, and the inserted part is non-circular, so that the rotary drive rod rotates to drive the adjusting screw to rotate synchronously. This improves the stability of the connection between the bus bar clamp and the copper bar, and improves the convenience of operation.

[0004] The patent has the following technical problems: the clamping jaws and the main conductor are operated separately, and the user needs to adjust the clamping jaws and the main conductor separately during use, which increases the operation steps and complexity. SUMMARY

[0005] In order to solve the above technical problem of complex operation, the present application provides a bus bar clamp, which only needs to be operated once to drive the functional components of the bus bar clamp to act in coordination, without the need to separately control the clamping, conductive and other structures, thereby greatly simplifying the operation process.

[0006] The specific technical solution of the present application is: a bus bar clamp, comprising a handle, a conductive assembly, a clamping assembly and a linkage assembly. The handle comprises a driving mechanism. The conductive assembly comprises a conductive sleeve and a conductive head in conductive connection with the clamping object, the driving mechanism is slidingly connected with the conductive sleeve, and the conductive head is slidingly sleeved in the conductive sleeve. The clamping assembly is in transmission connection with the driving mechanism, so that when the driving mechanism slides along the conductive sleeve towards the clamping assembly, the clamping assembly is driven to clamp. The connecting position of the conductive sleeve and the driving mechanism is provided with a through opening, and the conductive head is provided with a first groove, the through opening and the first groove both extend along the sliding direction of the driving mechanism, and the positions of the two correspond to form a placement space of a linkage assembly; One end of the linkage assembly extends into the through opening and is connected with the driving mechanism, and the other end extends into the first groove and is connected with the conductive head, so that the conductive head moves in the same direction by the sliding driving of the driving mechanism along the conductive sleeve.

[0007] In the above current collector clamp, the driving mechanism slides forward along the conductive sleeve, the clamping assembly performs clamping action, mechanical clamping of the clamped object is realized, and when the driving mechanism slides along the conductive sleeve, the linkage assembly pushes the conductive head to slide in the same direction along the inner cavity of the conductive sleeve, and the front end of the conductive head contacts the surface of the clamped object and is conductively connected with the surface. The disconnection only needs to move the driving mechanism backward, the clamping mechanism is loosened, and the conductive head moves backward and separates from the surface of the clamped object. The present application realizes that the conductive assembly extends forward and is conductively connected with the clamped object when the clamping assembly clamps, and the conductive assembly moves backward and is disconnected from the clamped object when the clamping assembly is loosened, only a single operation is needed to drive the functional components of the current collector clamp to act cooperatively, the clamping and conductive structures do not need to be controlled separately, the rapid connection and disconnection of the current collector clamp and the copper bar and other clamped objects are realized, and the operation process is greatly simplified.

[0011] In the above technical solution, the sliding of the linkage block in the second groove reserves a stroke for the clamping action, and at the initial stage of the sliding of the front pushing part, the force is mainly transmitted to the clamping assembly, the clamping assembly pre-clamps the clamped object, at this time the clamped object is preliminarily fixed, and when the linkage block slides to the limit position of the groove, the continuous sliding of the front pushing part will drive the conductive head to act through the linkage assembly, and at the same time the clamping assembly further increases the clamping force under the action of the same driving force, forming the synchronization of the conductive and the final clamping. The design drives the double structure in sequence through a single operation, avoids the interference between the conductive head and the clamping mechanism caused by the overlong extension of the conductive head, and ensures the movement stroke adaptation of the clamping mechanism and the conductive head.

[0012] Optionally, when the linkage block is at the limit position of the front end of the second groove, the rear end of the linkage block is in contact with the rear end of the first groove.

[0013] 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 interval, and will not be delayed or advanced due to the mispositioning of the grooves.

[0014] Optionally, the handle further comprises a fixed sleeve sleeved outside the conductive assembly, the fixed sleeve is fixed with the conductive sleeve, the driving mechanism comprises a front pushing part connected with the clamping assembly and a limiting sleeve provided at the rear end of the front pushing part and separate from the front pushing part, the limiting sleeve is rotatably sleeved outside the fixed sleeve, the fixed sleeve is provided with a limiting part corresponding to the limiting sleeve, one side of the limiting sleeve close to the limiting part is provided with a sliding groove, the limiting sleeve is provided with a first thread at the end of the sliding groove away from the front pushing part, and the limiting part is provided with a second thread at the end of the sliding groove close to the front pushing part, and a sliding gap is left between the first thread and the second thread.

[0016] Optionally, the clamping assembly comprises a connecting rod, a connecting part and a clamping mechanism, the tail end of the connecting rod is rotatably connected with the driving mechanism, the front end is rotatably connected with the clamping mechanism, one end of the connecting part is fixedly connected with the conductive sleeve, and the other end is rotatably connected with the clamping mechanism, so as to drive the clamping assembly to clamp when the driving mechanism slides along the conductive sleeve to the clamping assembly.

[0017] In the above technical solution, the driving mechanism slides forward along the conductive sleeve, the connecting rod pushes the clamping mechanism to rotate around the connecting part, the clamping mechanism performs clamping action, and mechanical clamping of the clamped object is realized.

[0019] In the technical solution, the first jaw and the second jaw are arranged oppositely, and a double connecting rod transmission is matched, a stable positioning is provided for the clamped object through the symmetrical "encircling type" clamping, unilateral force deviation is avoided, the double connecting rods synchronously transmit driving force when the driving mechanism slides, the two connecting ends of the connecting part are symmetrically arranged as the rotation fulcrums of the double jaws, the rotation tracks of the double jaws when subjected to force are completely symmetrical, and then the movement distances of the front ends are consistent, and clamping deviation of the first jaw and the second jaw is avoided.

[0020] In the technical solution, the two connecting ends of the connecting part are symmetrically arranged as the rotation fulcrums of the double jaws, the rotation tracks of the double jaws when subjected to force are completely symmetrical, and then the movement distances of the front ends are consistent, and clamping deviation caused by unsymmetrical fulcrums is avoided.

[0021] Optionally, the front end of the first jaw is provided with a first clamping part, the front end of the second jaw is provided with a second clamping part, and end faces of the first clamping part and the second clamping part close to the clamping space are sawtooth-shaped.

[0022] In the technical solution, the sawtooth shape increases the friction between the first clamping part, the second clamping part and the clamped object, the convex structure of the sawtooth can be embedded into the surface of the clamped object under the action of clamping force, displacement of the clamped object caused by equipment vibration and external force pulling in the use process is effectively prevented, the stability and reliability of the bus bar clamp connected with the copper bar are ensured, and the normal operation of the electrical system is ensured.

[0023] Optionally, a tooth surface structure or a sharp structure is arranged on the end face of the conductive head close to the clamping space.

DETAILED DESCRIPTION

[0030] The present application will be described below through specific embodiments. It should be understood that these embodiments are only used to illustrate the present application and not to limit the scope of the present application, and the changes and advantages that can be thought of by those skilled in the art without departing from the spirit and scope of the present application are included in the present application, and the appended claims and any equivalents thereof are the protection scope of the present application.

The materials, devices, and methods used in the present application are those that are conventionally used unless otherwise specified, and are available from commercial sources unless otherwise specified.

[0032] In the present application, terms such as "first" and "second" are merely used to distinguish one entity or operation from another, and do not necessarily require or imply any actual quantitative, primary / secondary, or sequential relationship between the entities or operations.

[0033] In the following examples, for the convenience of explanation, the direction from the clamping assembly to the handle is from front to back, and the direction from the clamping assembly to the handle is from front to back. The "front end" refers to the end close to the clamping assembly, and the "rear end" or "tail end" refers to the end away from the clamping assembly.

[0034] Example 1: Referring to Figures 1 to 6 The present application provides a current collecting clamp, comprising a handle 1, a conductive assembly 2, a clamping assembly 3 and a linkage assembly 4; The handle 1 is made of insulating material, which includes a driving mechanism 11 and a fixed sleeve 12 sleeved outside the conductive assembly 2. The driving mechanism 11 can slide along the axial direction of the conductive assembly 2. The driving mechanism 11 is used to drive the movement of the clamping assembly 3 and the conductive assembly 2, so that the conductive assembly 2 is in conductive connection with the clamped object when the clamping assembly 3 is in the clamping state; The conductive assembly 2 includes a conductive sleeve 21 and a conductive head 22 in conductive connection with the clamped object. The conductive head 22 is slidably sleeved in the conductive sleeve 21. The driving mechanism 11 is in sliding connection with the conductive sleeve 21. The fixed sleeve 12 is fixed with the conductive sleeve 21, that is, the driving mechanism 11 can slide relative to the fixed sleeve 12; The clamping assembly 3 is made of insulating material and is in transmission connection with the driving mechanism 11, so that when the driving mechanism 11 slides along the conductive sleeve 21 towards the clamping assembly 3, the driving mechanism 11 drives the clamping assembly 3 to clamp; The connection position of the conductive sleeve 21 and the driving mechanism 11 is provided with a through opening 211. The conductive head 22 is provided with a first recess 221. The through opening 211 and the first recess 221 both extend along the sliding direction of the driving mechanism 11. The positions of the two form a placement space of the linkage assembly 4; One end of the linkage assembly 4 extends into the through opening 211 and is connected with the driving mechanism 11. The other end extends into the first recess 221 and is connected with the conductive head 22, so as to drive the conductive head 22 to move in the same direction through the sliding of the driving mechanism 11 along the conductive sleeve 21.

[0035] The driving mechanism 11 slides along the conductive sleeve 21, the clamping assembly 3 performs a clamping action, mechanical clamping of the clamped object is achieved, and when the driving mechanism 11 slides along the conductive sleeve 21, the linkage assembly 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 clamped object and is in conductive connection with the surface of the clamped object; conversely, the operator pulls the driving mechanism 11 back, so that the clamping assembly 3 is loosened, and the linkage assembly 4 drives the conductive head 22 to move backward and separate from the surface of the clamped object.

[0036] The driving mechanism 11 is respectively in transmission connection with the clamping assembly 3 and the conductive assembly 2, the conductive assembly 2 is extended forward to be in conductive connection with the clamped object when the clamping assembly 3 is clamped, the conductive assembly 2 moves backward to be disconnected from the clamped object when the clamping assembly 3 is loosened, only single operation is needed to drive the function assemblies of the bus bar clamp to act cooperatively, the clamping and conductive structures do not need to be controlled separately, the bus bar clamp and the clamped object such as a copper bar are quickly connected and disconnected, and the operation process is greatly simplified.

[0037] The fixed sleeve 12 is open at an end away from the driving mechanism 11 to expose the conductive sleeve 21, and the conductive sleeve 21 and external electrical components can be connected through the opening.

[0038] The linear sliding between the driving mechanism 11 and the fixed sleeve 12 and the linear sliding between the driving mechanism 11 and the conductive sleeve 21 can be realized through the structure of the linear sliding block sliding groove 18. For example, the outer wall of the conductive sleeve 21 is provided with the sliding groove 18 extending in the axial direction, the driving mechanism 11 is provided with a matching sliding block, the sliding block can slide along the sliding groove 18, and thus the driving mechanism 11 can slide linearly along the sliding groove 18 of the conductive sleeve 21 through the sliding block. An appropriate matching gap is reserved between the sliding groove 18 and the sliding block, and grease or self-lubricating material (such as PTFE coating) can be coated or built-in to reduce the friction resistance.

[0039] Please refer to Figure 1 and Figure 2 In 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 rotationally connected with the driving mechanism 11, the front end is rotationally connected with the clamping mechanism 33, one end of the connecting part 31 is fixedly connected with the conductive sleeve 21, the other end is rotationally connected with the clamping mechanism 33, so that the clamping assembly 3 is driven to clamp when the driving mechanism 11 slides along the conductive sleeve 21 to the direction of the clamping assembly 3.

[0040] Please refer to Figure 1 The driving mechanism 11 slides 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 mechanical clamping of the clamped object is achieved.

[0041] Please refer to Figure 1 and Figure 2In some embodiments, the linkage assembly 4 includes a linkage block 41 and a resilient member 42. One end of the linkage block 41 extends into the through opening 211 and is connected to the driving mechanism 11, and the other end extends into the first recess 221 and is connected to the conductive head 22. The resilient member 42 is arranged in the first recess 221 and gives the linkage block 41 a pre-tightening force in the opposite direction of the driving mechanism 11. When the driving mechanism 11 is not subjected to external force, the resilient member 42 pushes the driving 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 loosening, and the linkage block 41 drives the conductive head 22 to move backward along the inner cavity of the conductive sleeve 21, so that the conductive head 22 is separated from the surface of the clamped object, thereby achieving automatic resetting of the functional assembly and simplifying the operation process.

[0042] The first recess 221 has two opposite side walls: one near the clamping mechanism 33 (i.e. the front end direction), referred to as the "near clamping mechanism 33 side wall", and the other away from the clamping mechanism 33 (i.e. the rear end direction), referred to as the "far clamping mechanism 33 side wall". One end of the resilient member 42 is fixed on the near clamping mechanism 33 side wall, and the other end is fixed on the side of the linkage block 41 facing the near clamping mechanism 33 side wall. The first recess 221 is used to accommodate and guide the movement of the linkage block 41 and provide installation space for the resilient member 42. In the initial state, the resilient member 42 is in a natural stretched state, the linkage block 41 abuts against the far clamping mechanism 33 side wall of the first recess 221, and the entire device is in a standby state, with the clamping mechanism 33 opened to the maximum angle for easy clamping of the clamped object. It should be noted that the specific type of the resilient member 42 is not limited in the present application, whether it is a metal coil spring, an elastic rubber column or other elastic structures with elastic resetting or force transmission functions, as long as it can achieve the above-mentioned functions of the existing elastic structure, it falls within the scope of protection of the present application.

[0043] When the operator pushes the driving mechanism 11 forward, the operator's pushing force overcomes the pre-tightening force of the resilient member 42, and then drives the clamping of the clamping mechanism 33 and the forward extension of the conductive head 22. If the conductive head 22 contacts the copper bar in advance, the operator continues to push the driving mechanism 11, the linkage block 41 will slide relatively in the first recess 221 of the conductive head 22, further compressing the resilient member 42, until the clamping mechanism 33 completely clamps the clamped object. Conversely, if the clamping mechanism 33 contacts and clamps the copper bar before the conductive head 22, at this time the conductive head 22 has not yet conducted with the copper bar, when the operator stops pushing the driving mechanism 11 and fixes its position, the compressed resilient member 42 will release its stored elastic potential energy and apply a pushing force to the clamping mechanism 33, pushing the conductive head 22 to continue to slide forward relative to the conductive sleeve 21 until its front end reliably contacts the surface of the copper bar, completing the electrical connection. By arranging the resilient member 42 between the linkage block 41 and the front end of the conductive head 22, the compensation of clamping and conduction is cleverly achieved.

[0044] Further, the driving mechanism 11 comprises a front pushing part 16 connected with the tail end of the connecting rod 32, and the front pushing part 16 is provided with a second groove 14 extending along the sliding direction of the driving mechanism 11. In the horizontal direction, the rear end of the second groove 14 is more rearward than the rear end of the first groove 221. One end of the linkage block 41 extends into the second groove 14 and is in sliding connection with the second groove 14, that is, the linkage block 41 can relatively move in the second groove 14 along the sliding direction of the driving mechanism 11, instead of being fixed, so that the driving mechanism 11 drives the clamping assembly 3 to move first and then drives the conductive head 22 to move when the driving mechanism 11 slides along the conductive sleeve 21. The sliding of the linkage block 41 in the second groove 14 reserves a stroke for the clamping action. At the initial stage of the sliding of the front pushing part 16, the force is mainly transmitted to the clamping assembly 3 through the connecting rod 32, and the clamping assembly 3 pre-clamps the clamped object. At this time, the clamped object is preliminarily fixed. When the linkage block 41 slides to the limit position of the groove, the continuous sliding of the front pushing part 16 drives the conductive head 22 to move through the linkage assembly 4, and at the same time, the clamping assembly 3 further increases the clamping force under the action of the same driving force, so that the synchronization of the conduction and the final clamping is completed. The design drives the double structures in sequence through a single operation, avoids the interference between the conductive head 22 and the clamping mechanism 33 caused by the overlong extension of the conductive head 22, and ensures the movement stroke adaptation of the clamping mechanism 33 and the conductive head 22.

[0045] It should be noted that the present application does not limit the specific length of the first groove 221 and the second groove 14. The length of the second groove 14 and the first groove 221 should follow the following rules: the length of the second groove 14 should be slightly greater than the effective stroke of the connecting rod 32 for driving the clamping mechanism 33 to complete the “loose-clamp” action, so as to ensure the complete realization of the clamping function; the length of the first groove 221 should be not less than the sum of the stroke of the linkage block 41 for driving the conductive assembly 2 to complete the “disconnect-communicate” action and the deformation stroke of the elastic member 42, so as to ensure the reliability of the conduction function and the reset; 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 lock the action time sequence of “the conductive assembly 2 is behind the clamping mechanism 33 in action” through the length difference from the structure, and avoid the action conflict or function failure caused by the stroke mismatch.

[0046] Further, when the linkage block 41 is at the front limit position of the second groove 14, the rear end of the linkage block 41 is in contact with the rear end of the first groove 221. The positions of the first groove 221 and the second groove 14 are connected, which ensures that after the clamping assembly 3 completes the pre-clamping, the conductive head 22 can immediately enter the effective action interval, and will not be delayed or advanced in action due to the mispositioning of the groove.

[0047] Please refer to Figure 1 and Figure 2In some embodiments, the driving mechanism 11 comprises a front pushing part 16 connected to the tail end of the connecting rod 32 and a limiting sleeve 13 arranged at the rear end of the front pushing part 16 and separated from the front pushing part 16. The limiting sleeve 13 is rotatably sleeved on the fixed sleeve 12, and the fixed sleeve 12 is provided with a limiting part 17 corresponding to the limiting sleeve 13. The side of the limiting sleeve 13 close to the limiting part 17 is provided with a sliding groove 18, and the end of the limiting sleeve 13 away from the front pushing part 16 is provided with a first thread, and the end of the limiting part 17 close to the front pushing part 16 is provided with a second thread matched with the first thread, and a sliding gap 15 is left between the first thread and the second thread. The limiting sleeve 13 moves forward together with the front pushing part 16, the first thread and the second thread gradually approach, the sliding gap 15 between them is reduced, until they abut, the limiting sleeve 13 rotates relative to the fixed sleeve 12, and the front pushing part 16 is continuously pushed forward. When the clamping assembly 3 is in the clamping state and the conductive assembly 2 is in conductive connection with the clamped object, stop rotating, lock the position of the front pushing part 16, to ensure that the current clamp is stably connected with the clamped object without loosening, and improve the convenience and stability of the operation. It can be understood that the extension direction of the sliding groove 18 can be flexibly set, which can extend from the front end close to the front pushing part 16 to the rear end, or extend from the rear end away from the front pushing part 16 to the front end, as long as the limiting part 17 can form effective limiting in the sliding groove 18 when the limiting sleeve 13 slides with the front pushing part 16.

[0048] In the embodiment provided with the second groove 14, the length of the sliding gap 15 is greater than the length of the second groove 14, which can ensure that when the front pushing part 16 drives the linkage block 41 to complete the complete stroke of the driving clamping mechanism 33 "loose-clamp", the first thread and the second thread are still in the unmeshing state, avoiding the interference of thread cooperation in advance to interfere with the clamping action. After the clamping mechanism 33 completes the clamping, the front pushing part 16 continues to slide to gradually reduce the sliding gap 15, until the first thread and the second thread are engaged, and then the limiting sleeve 13 is rotated to lock the position of the front pushing part 16.

[0049] As Figures 4 to 6As shown, when the bus bar is in the initial state, the front end of the linkage block 41 is in contact with the front end of the second groove 14, the rear end is in contact with 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 portion 17, and the maximum sliding gap 15 is maintained between them; then the front pushing portion 16 and the limiting sleeve 13 are pushed forward together and slide, until the rear end of the linkage block 41 is in contact with the rear end of the second groove 14, the first thread of the limiting sleeve 13 gradually approaches the second thread of the limiting portion 17, the sliding gap 15 between them is reduced, the connecting rod 32 slides with the front pushing portion 16 to drive the clamping mechanism 33 to rotate around the connecting portion 31, and the clamping mechanism 33 is pre-clamped at this time; then the front pushing portion 16 and the limiting sleeve 13 are continuously pushed forward together under the action of the driving force, the conductive head 22 is moved forward under the action of the linkage assembly 4, and the clamping assembly 3 further increases the clamping force under the action of the same driving force, the sliding gap 15 between the first thread and the second thread is reduced, until they abut, the limiting sleeve 13 rotates relative to the fixed sleeve 12, and the front pushing portion 16 is continuously pushed forward, until the bus bar is in the final clamping state, at which time the conductive and the final clamping are completed synchronously, and the position of the front pushing portion 16 is locked under the threaded connection of the limiting sleeve 13 and the limiting portion 17, ensuring the continuity of the connection.

[0050] Please refer to Figure 1 In some embodiments, the clamping mechanism 33 includes a first jaw and a second jaw arranged oppositely, the tail ends of the first jaw and the second jaw are respectively connected with the driving mechanism 11 through a connecting rod 32, the connecting portion 31 is sleeved outside the conductive sleeve 21, two connecting ends are symmetrically arranged on the connecting portion 31 and are respectively connected with the middle portions of the first jaw and the second jaw, the first jaw and the second jaw form a clamping space 6, and the conductive head 22 is driven by the driving mechanism 11 to be in conductive connection with the clamped object in the clamping space 6. The first jaw and the second jaw are arranged oppositely and are driven by the double connecting rods, and the clamped object is stably positioned by the symmetrical "encircling" clamping, avoiding unilateral force deviation, the driving mechanism 11 slides and the double connecting rods synchronously transmit the driving force, the two connecting ends of the connecting portion 31 are symmetrically arranged as the rotation fulcrums of the double jaws, ensuring that the rotation trajectories of the double jaws are completely symmetrical when they are stressed, and further ensuring that the front ends have consistent movement distances, avoiding clamping deviation of the first jaw and the second jaw.

[0051] Further, the front end of the first clamping jaw is provided with a first clamping part, and the front end of the second clamping jaw is provided with a second clamping part; the end face of the first clamping part and the second clamping part close to the clamping space 6 is serrated. The serration increases the friction between the first clamping part, the second clamping part and the clamped object. In actual use, the surface of the clamped object may have certain roughness differences, or there may be slight oil stains, oxidation layers, etc. The protruding structure of the serration can be embedded into the surface of the clamped object under the action of the clamping force, effectively preventing the displacement of the clamped object caused by equipment vibration or external force pulling during use, ensuring the stability and reliability of the connection between the bus clamp and the copper bar, and ensuring the normal operation of the electrical system.

[0052] The end face of the conductive head 22 close to the clamping space 6 is provided with a tooth surface structure or a sharp structure. The tooth surface structure or the sharp structure can facilitate increasing the friction between the conductive head 22 and the surface of the clamped object, ensuring the contact stability, and breaking the oxidation film that may exist on the surface of the clamped object, so that the metal material of the conductive head 22 directly contacts the body of the clamped object, reducing the contact resistance and ensuring efficient transmission of electric energy.

[0053] Referring to Figure 1 In some embodiments, a watchband finger groove 5 is provided on the side wall of the conductive head 22, and a watchband finger is installed in the watchband finger groove 5, which is tightly attached to 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, bring efficient and stable current transmission to the power system, and effectively avoid electrical connection failure between the sliding sleeve connected conductive head 22 and the conductive sleeve 21.

[0054] Referring to Figure 1 and Figure 3 In some embodiments, the longitudinal section of the conductive head 22 is a T-shaped structure. The head of the conductive head 22 extends out of the conductive sleeve 21, and the tail of the conductive sleeve 21 can be rod-shaped, and a first groove 221 is provided on the tail in the conductive sleeve 21. The head of the conductive head 22 has a larger area than the tail, which can provide a larger contact area with the clamped object, which is conducive to establishing more stable electric energy transmission.

Any simple modification, change and equivalent transformation of the above embodiment based on the technical essence of the present application still falls within the protection scope of the technical solution of the present application.
