Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and particularly relates to a compact power-taking clip. Background Art

[0002] A power-taking clip is an emergency power socket applied to a low-voltage power distribution cabinet, and a power generation vehicle or other power generation equipment can output electric energy to the power distribution cabinet through this device. As an intermediate component for delivering electric energy to the power distribution cabinet, the power-taking clip needs to adapt to the working conditions of the electric contact busbar that receives electric energy. Since the power generation equipment delivers a relatively large amount of electric energy externally, the contact area between the power-taking clip and the electric contact busbar needs to meet the working requirements of high-power electric energy transmission. This results in that the volume of the electric contact part of the power-taking clip cannot be reduced arbitrarily. In some working equipment, the position where the electric contact busbar is located is relatively narrow, and the traditional power-taking clip cannot be directly connected to the electric contact busbar, and some equipment near the electric contact busbar position needs to be disassembled, which greatly reduces the working efficiency of the power generation equipment in outputting electric energy externally. Therefore, it is necessary to propose a compact power-taking clip in view of the disadvantage that the traditional power-taking clip is difficult to be arranged in a narrow space. Utility Model Content

[0003] Based on this, it is necessary to propose a compact power-taking clip in view of the disadvantage that the traditional power-taking clip is difficult to be arranged in a narrow space.

[0004] The present application relates to a compact power-taking clip, including:

[0005] A base, including a top block, a connecting column, and a bottom block. The connecting column is arranged between the top block and the bottom block. The top block is fixedly connected to the connecting column, and the bottom block is fixedly connected to the connecting column. The top surface of the top block is parallel to the bottom surface of the bottom block. The top block is provided with a guiding hole, the connecting column is provided with a receiving groove, the bottom block is provided with a threaded hole, and the guiding hole is communicated with the receiving groove;

[0006] A slider, including a block body, a finger, and a sliding rod. The sliding rod is arranged in the inner cavity of the guiding hole, the sliding rod extends into the interior of the receiving groove, the finger is attached to the groove wall of the receiving groove, a preset part of the block body extends into the interior of the receiving groove, the block body is sleeved on the outer peripheral surface of the sliding rod, and the top surface of the block body is parallel to the top surface of the top block;

[0007] A threaded rod, threadedly connected to the threaded hole, and the top of the threaded rod is connected to the bottom of the block body;

[0008] A toroid, fixedly connected to the side wall of the bottom block. The central axis of the toroid is perpendicular to the central axis of the threaded hole. The toroid is arranged close to the connecting column, and the connecting column is provided with an arc surface, and the arc surface is arranged close to the cylindrical surface of the toroid;

[0009] A conductor is sleeved on the outer peripheral surface of the toroidal body.

[0010] The present application relates to a compact power-taking clamp. Through the top block, connecting column and bottom block of the base, a basic structure for clamping and electrically contacting the busbar is formed, ensuring that the contact area between the power-taking clamp and the electrically contacting busbar meets the working requirements of high-power power transmission. The preset part of the block body of the slider extends into the interior of the accommodating groove, and the block body is sleeved on the outer peripheral surface of the sliding rod, which realizes the control of the volume of the slider and prevents the overall volume of the power-taking clamp from being too large, resulting in low power supply efficiency for the operator. The threaded rod can be threadedly advanced in the threaded hole of the bottom block, and the top of the threaded rod is connected to the bottom of the block body. Threaded advancement along the central axis of itself can cause the block body to move towards the top block, thereby realizing the effect of the top block and the block body clamping the electrically contacting busbar. The block body is connected to the base, and guides the electric energy guided by the base to the electrically contacting busbar. The toroidal body is arranged close to the bottom block, and the connecting column is connected to the top surface of the bottom block, which greatly reduces the volume of the power-taking clamp.

[0024] In order to make the purpose, technical solution and advantages of this application clearer, the following further details this application in combination with the attached drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

[0025] This application provides a compact power - taking clamp.

[0026] As Figure 1 shown, in an embodiment of this application, a compact power - taking clamp includes a base 100, a slider 200, a threaded rod 300, a torus 400 and a conductor 500.

[0027] The base 100 includes a top block 110, a connecting column 120 and a bottom block 130. The connecting column 120 is arranged between the top block 110 and the bottom block 130. The top block 110 is fixedly connected to the connecting column 120, and the bottom block 130 is fixedly connected to the connecting column 120. The top surface of the top block 110 is parallel to the bottom surface of the bottom block 130. The top block 110 is provided with a guiding hole 111, the connecting column 120 is provided with a receiving groove 121, the bottom block 130 is provided with a threaded hole 131, and the guiding hole 111 communicates with the receiving groove 121.

[0028] The slider 200 includes a block body 210, a contact finger 220 and a sliding rod 230. The sliding rod 230 is arranged in the inner cavity of the guiding hole 111, the sliding rod 230 extends into the inside of the receiving groove 121, the contact finger 220 adheres to the groove wall of the receiving groove 121, a preset part of the block body 210 extends into the inside of the receiving groove 121, the block body 210 is sleeved on the outer peripheral surface of the sliding rod 230, and the top surface of the block body 210 is parallel to the top surface of the top block 110.

[0029] The threaded rod 300 is threadedly connected to the threaded hole 131, and the top of the threaded rod 300 is connected to the bottom of the block body 210.

[0030] The toroid 400 is fixedly connected to the side wall of the bottom block 130. The central axis of the toroid 400 is perpendicular to the central axis of the threaded hole 131. The toroid 400 is disposed close to the connecting column 120. The connecting column 120 is provided with an arc surface 122, and the arc surface 122 is disposed close to the cylindrical surface of the toroid 400.

[0031] The conductor 500 is sleeved on the outer peripheral surface of the toroid 400.

[0032] This embodiment relates to a compact power-taking clip. Through the top block 110, the connecting column 120 and the bottom block 130 of the base 100, a basic structure for clamping and electrically contacting the busbar is formed, ensuring that the contact area between the power-taking clip and the electrically contacting busbar meets the working requirements of high-power power transmission. The preset part of the block body 210 of the slider 200 extends into the inside of the accommodating groove 121, and the block body 210 is sleeved on the outer peripheral surface of the sliding rod 230, which realizes the control of the volume of the slider 200 and prevents the overall volume of the power-taking clip from being too large, resulting in low power supply efficiency for the operator. The threaded rod 300 can be thread-fed in the threaded hole 131 of the bottom block 130. The top of the threaded rod 300 is connected to the bottom of the block body 210. The thread feeding along its own central axis direction can realize the movement of the block body 210 towards the top block 110, and further realize the effect of clamping the electrically contacting busbar by the top block 110 and the block body 210. The block body 210 is connected to the base 100, and guides the electric energy guided by the base 100 to the electrically contacting busbar. The toroid 400 is disposed close to the bottom block 130, and the connecting column 120 is connected to the top surface of the bottom block 130, which greatly reduces the volume of the power-taking clip.

[0033] As Figure 1 shown, in an embodiment of the present application, a clamping groove 240 is provided at the bottom of the slider 200. The clamping groove 240 includes a first sub-groove 241 and a second sub-groove 242. The first sub-groove 241 and the second sub-groove 242 are in mutual communication. The first sub-groove 241 is disposed close to the top block 110. The projections of the second sub-groove 242 in the direction perpendicular to the bottom surface of the first sub-groove 241 are all within the accommodating range of the first sub-groove 241.

[0034] Specifically, through the first sub-groove 241 of the clamping groove 240 and the second sub-groove 242 of the clamping groove 240, the top of the threaded rod 300 can be clamped at the bottom of the slider 200.

[0035] The projections of the second sub-groove 242 in the direction perpendicular to the bottom surface of the first sub-groove 241 are all within the accommodating range of the first sub-groove 241, which realizes the relative rotation of the threaded rod 300 with respect to the bottom block 130. Since the threaded rod 300 rotates relative to the threaded hole 131 of the bottom block 130, the threaded rod 300 can move along its own central axis, and further the relative displacement of the slider 200 with respect to the top block 110 can be realized.

[0036] As Figure 1 and Figure 4 shown, in an embodiment of the present application, a clamping body 310 is provided at the top of the threaded rod 300. The clamping body 310 includes a first split body 311 and a second split body 312. The diameter of the first split body 311 is greater than the diameter of the second split body 312. The central axis of the first split body 311 coincides with the central axis of the second split body 312. The second split body 312 is fixedly connected to the top of the threaded rod 300. The first split body 311 is fixedly connected to the second split body 312.

[0037] Specifically, a clamping body 310 is provided at the top of the threaded rod 300, and mutual clamping with the clamping groove 240 is achieved through the clamping body 310. Since the diameter of the first split body 311 is greater than the diameter of the second split body 312, the second split body 312 can be clamped in the second secondary groove 242, and the first split body 311 can be clamped in the first secondary groove 241.

[0038] The clamping body 310 can rotate relative to the clamping groove 240.

[0039] As Figure 1 shown, in an embodiment of the present application, the second secondary groove 242 includes a receiving round hole 243 and a clamping round hole 244. The receiving round hole 243 and the clamping round hole 244 communicate with each other. The first split body 311 of the clamping body 310 extends into the first secondary groove 241 through the receiving round hole 243. The second split body 312 of the clamping body 310 is clamped in the clamping round hole 244.

[0040] Specifically, the diameter of the first split body 311 of the clamping body 310 is greater than the diameter of the second split body 312 of the clamping body 310. The first split body 311 of the clamping body 310 abuts against the bottom of the first secondary groove 241 of the clamping groove 240 through the receiving round hole 243. The second split body 312 of the clamping body 310 is clamped in the clamping round hole 244 of the second secondary groove 242 of the clamping groove 240. The diameter of the clamping round hole 244 is equal to the diameter of the second split body 312 of the clamping body 310. The diameter of the receiving round hole 243 is equal to the diameter of the first split body 311 of the clamping body 310.

[0041] As Figure 3 shown, in an embodiment of the present application, the conductor 500 includes a conductive rod 510 and a contact ring 520. The contact ring 520 is sleeved on the outer peripheral surface of the toroidal body 400. The conductive rod 510 is sleeved on the outer peripheral surface of the contact ring 520.

[0042] Specifically, good contact between the conductive rod 510 and the toroidal body 400 can be achieved through the contact ring 520. Compared with poor electrical contact, good electrical contact can reduce the contact area of the electrical contact.

[0043] On the one hand, during the process that the contact ring 520 receives the rotation of the conductive rod 510 relative to the outer peripheral surface of the contact ring 520, the contact ring 520 can collapse along its own diameter direction, thereby reducing the friction with the inner wall of the through hole of the conductive rod 510.

[0044] On the other hand, the contact ring 520 can expand and contract in its own diameter direction. Therefore, in the absence of external force, the contact ring 520 can abut against the inner wall of the through hole of the conductive rod 510, thereby realizing good electrical contact between the contact ring 520 and the inner wall of the through hole of the conductive rod 510.

[0045] As Figure 2 shown, in an embodiment of the present application, both the contact finger 220 and the contact ring 520 include a plurality of contact piece monomers 600. The plurality of contact piece monomers 600 are sequentially connected to each other to form the contact finger 220. The plurality of contact piece monomers 600 are sequentially connected to each other to form an annular body to constitute the contact ring 520.

[0046] Specifically, the contact finger 220 is a linear strip. The contact ring 520 is an annular strip. Both the contact finger 220 and the contact ring 520 are composed of a plurality of contact piece monomers 600 arranged in sequence.

[0047] The electrical contact structure composed of a plurality of contact piece monomers 600 has good electrical contact performance.

[0048] As Figure 4 shown, in an embodiment of the present application, the contact piece monomer 600 includes a contact piece body 610, a connecting band 620 and a holding foot 630. The holding foot 630 is fixedly connected to the contact piece body 610. The connecting band 620 includes a plurality of connecting areas 621 and a bracket 622. Each of the connecting areas 621 is parallel to each other. The included angle between the connecting area 621 and the bracket 622 is in the angular range of greater than or equal to 5 degrees and less than or equal to 15 degrees. Adjacent connecting areas 621 are fixedly connected by the bracket 622. The holding foot 630 is clamped in the connecting area 621.

[0049] Specifically, the contact piece body 610 is used to contact the inner wall of the through hole of the conductive rod 510.

[0050] The connecting area 621 of the connecting band 620 is used to contact the circular ring body 400. The connecting area 621 of the connecting band 620 can be a linear strip. The connecting area 621 of the connecting band 620 can also be an annular strip.

[0051] The bracket 622 is used to connect the contact piece body 610 and the connecting band 620. The bracket 622 is used to generate elastic force.

[0052] The included angle between the connection area 621 and the bracket 622 is in the angular range of greater than or equal to 5 degrees and less than or equal to 15 degrees. The larger the included angle, the larger the collapse space that the contact piece body 610 can provide.

[0053] As Figure 1 shown, in an embodiment of the present application, the conductive rod 510 includes a conductive block 511, a base column 512, and a connecting pipe 513. The conductive block 511 is sleeved on the outer peripheral surface of the contact ring 520 through a round hole. The conductive block 511, the base column 512, and the connecting pipe 513 are fixedly connected in sequence. A clamping ring 518 is sleeved at the connection between the base column 512 and the connecting pipe 513. The clamping ring 518 is connected with an insulating pipe 514. The insulating pipe 514 is sleeved on the outer peripheral surfaces of the conductive block 511, the base column 512, and the connecting pipe 513.

[0054] Specifically, the conductive block 511, the base column 512, and the connecting pipe 513 of the conductive rod 510 are all conductors, and can conduct electric energy to the contact ring 520, the circular ring body 400, the slider 200, and the base 100.

[0055] The clamping ring 518 is arranged between the conductive rod 510 and the insulating pipe 514. The insulating pipe 514 is used to protect the operator from contacting the live conductor. One end of the clamping ring 518 is clamped at the connection between the base column 512 and the connecting pipe 513. The other end of the clamping ring 518 abuts against and is clamped on the inner wall of the insulating pipe 514.

[0056] As Figure 1 shown, in an embodiment of the present application, the conductive rod 510 further includes a return spring 515 and a guide rod 516. One end of the return spring 515 abuts against the end face of the inner cavity of the connecting pipe 513. The inner cavity of the connecting pipe 513 is provided with threads. The guide rod 516 is threadedly connected with the inner cavity of the connecting pipe 513. The other end of the return spring 515 abuts against the end face of the guide rod 516.

[0057] Specifically, one end of the return spring 515 abuts against the end face of the inner cavity of the connecting pipe 513, and the other end of the return spring 515 abuts against the end face of the guide rod 516. This is to prevent the threaded connection between the guide rod 516 and the inner cavity of the connecting pipe 513 from being loose.

[0058] More specifically, the recoil spring 515 can apply an elastic force to the guide rod 516. There is pressure between the threads of the guide rod 516 and the internal cavity threads of the connecting pipe 513. When there is a tendency of rotation between the threads of the guide rod 516 and the internal cavity threads of the connecting pipe 513, static friction can exist between the threads of the guide rod 516 and the internal cavity threads of the connecting pipe 513. Furthermore, the torque generated by the static friction is used to counteract the rotational torque, thereby achieving a tight connection between the threads of the guide rod 516 and the internal cavity of the connecting pipe 513.

[0059] As Figure 1 shown, in an embodiment of the present application, the conductive rod 510 further includes a connecting ring 517. The connecting ring 517 and the end of the connecting pipe 513 away from the base column 512 are engaged with each other. The diameter of the end of the guide rod 516 away from the base column 512 is smaller than the inner diameter of the connecting pipe 513.

[0060] Specifically, the connecting ring 517 and the end of the connecting pipe 513 away from the base column 512 are engaged with each other. The connecting ring 517 is used to hold the power transmission cable. The guide rod 516 is used to guide the power transmission cable, increasing the contact area between the power transmission cable and the inner wall of the conductive rod 510 and increasing the contact area between the power transmission cable and the outer wall of the conductive rod 510.

[0061] The technical features of the above-described embodiments can be combined arbitrarily, and there is no limitation on the execution order of the method steps. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0062] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the patent scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
