Description

Technical Field

[0001] This application relates to the field of power connectors, and more specifically, to an emergency live quick-install socket. Background Technology

[0002] A substation is a location in a power system that transforms voltage and current, receives electrical energy, and distributes it. Substations within power plants are step-up substations, whose function is to step up the voltage of the electrical energy generated by generators before feeding it into the high-voltage power grid. During the daily use of substations and high-voltage switchgear, testing and maintenance are required, necessitating connections via external connectors.

[0003] The structure of the high-voltage switchgear or substation and the emergency connector used in the substation refers to the clamping section structure of a connector disclosed in Chinese patent document CN214280220U. In use, external force controls the rotation of the conductive screw, bringing the first conductive axis closer to the second conductive axis, thereby bringing the first conductive contact finger closer to the second conductive contact finger. This connects the copper sheet busbar or other types of busbars used for circuit connections within the high-voltage switchgear or substation. At this time, external testing and maintenance equipment requiring power is electrically connected to the conductive screw, allowing power to be drawn from the high-voltage switchgear or substation.

[0004] During use, it was found that in the above structure, the conductive screw can still rotate during power extraction and when connecting external electrical equipment to the connector. This causes the first conductive contact to move away from the second conductive contact, resulting in unstable connections between the connector and the high-voltage cabinet, substation, or transformer. Since this connection is in a high-voltage environment, instability not only makes inspection and maintenance inconvenient but may also generate electrical sparks between the conductive contacts and the wire bar, posing a safety hazard.

[0005] Currently, there is no safe and stable emergency live-line quick-install socket that can be used. Summary of the Invention

[0006] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0007] To address the technical problems mentioned in the background section, some embodiments of this application provide an emergency live quick-install socket, comprising: a contact, a mounting base, and a connector; wherein the contact is used to contact a busbar to draw power from the busbar; the mounting base is used to mount the contact and provide space for the contact to slide relative to the mounting base; the connector is used to provide at least one conductive shaft connected to the contact to push the contact to move when the connector is moved; the conductive shaft is threadedly connected to the mounting base to drive the contact to move when the connector rotates forward relative to the mounting base; the mounting base is provided with a first anti-rotation structure; the conductive shaft is provided with a second anti-rotation structure that cooperates with the first anti-rotation structure to prevent the conductive shaft from rotating in reverse relative to the mounting base.

[0008] When the conductive shaft rotates forward, it slides relative to the mounting base, clamping the cable tray inside the high-voltage cabinet or substation via the contact element and mounting base. After drawing power from the high-voltage cabinet, the cooperation of the first rotating structure and the second anti-rotation structure prevents the conductive shaft from reversing, ensuring a stable and secure connection between the emergency live-line quick-install socket and the cable tray. This reduces the likelihood of electrical sparks during the process of connecting external electrical equipment to the connector and drawing power from the connector, resulting in higher safety during use. Thus, the emergency live-line quick-install socket of this application has the advantages of stable connection and safe use. Furthermore, this emergency live-line quick-install socket can be installed onto the cable tray without disconnecting the power, making operation more convenient and faster.

[0009] Furthermore, the first anti-rotation structure includes at least one first blocking surface; the second anti-rotation structure includes a plurality of second blocking surfaces, each second blocking surface being circumferentially distributed on the conductive shaft; the first blocking surface and the second blocking surface at least partially overlap to prevent the conductive shaft from reversing relative to the mounting base.

[0010] Furthermore, the first anti-rotation structure also includes a first clearance surface corresponding to the first blocking surface; the first clearance surface is inclined to the first blocking surface; the second anti-rotation structure also includes a second clearance surface corresponding to the second blocking surface; when the conductive shaft rotates clockwise relative to the mounting base, the second clearance surface is located in front of the second blocking surface; the second clearance surface and the first clearance surface at least partially overlap, so as to guide the first anti-rotation structure to avoid the conductive shaft when the conductive shaft rotates clockwise relative to the mounting base.

[0011] Furthermore, the second anti-rotation structure is integrally formed / fixedly connected to the conductive shaft.

[0012] Furthermore, the second anti-rotation structure is rotatably connected to the conductive shaft, and a locking structure is slidably provided on the second anti-rotation structure; the connector includes a housing for the user to hold, the end of the conductive shaft away from the mounting base is inserted into the housing and fixedly connected to the housing; the housing is provided with a locking part that cooperates with the locking structure, so as to restrict the rotation of the second anti-rotation structure relative to the housing when the locking part contacts the locking structure.

[0013] Furthermore, the locking structure includes a spacer ring and a slider; the spacer ring is sleeved on the conductive shaft and has a groove; the slider is slidably disposed in the groove, with an elastic element fixedly connected to one end near the groove and a toothed portion at the other end away from the groove; the locking portion is a toothed groove distributed circumferentially on the housing; the toothed portion is embedded in the toothed groove, thereby restricting the rotation of the locking structure relative to the housing.

[0014] Furthermore, an arc-shaped groove is provided at the end of the slider away from the slide groove, and the toothed part is located outside the arc-shaped groove; the connector also includes: a button and an arc-shaped piece; the button is slidably disposed on the housing; the arc-shaped piece is fixed on the button and located between the button and the slider; the arc-shaped piece is inserted into the arc-shaped groove so that when the button slides relative to the housing, it can push the slider to slide relative to the spacer ring.

[0015] Furthermore, the number of sliders on the spacer ring is at least two, and correspondingly, the number of buttons is at least two.

[0016] The beneficial effect of this application is that it provides a specific, safe, and stable emergency live-line quick-installation socket. Attached Figure Description

[0039] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] Example 1

[0041] Reference Figure 1-10 An emergency live-line quick-install socket includes: a contact 1, a mounting base 2, and a connector 3. The contact 1 is used to contact a cable strip to draw power from it. The mounting base 2 is used to mount the contact 1 and provide space for the contact 1 to slide relative to the mounting base 2. Specifically, the mounting base 2 is a shell made of insulating material. A conductive metal part 21 is fixedly disposed within the mounting base 2. The conductive metal part 21 has a movable groove 22, one side of which is open to allow insertion of the cable strip. The area of ​​the movable groove 22 is the space for the contact 1 to slide relative to the mounting base 2. When the cable strip is inserted into the movable groove 22, the contact 1 slides within the groove 22, clamping the cable strip between the conductive metal part 21 and the contact 1. Conductive fingers 4 are fixedly disposed on the contact 1 and the conductive metal part 21 on the side that contacts the cable strip, respectively. The two conductive fingers 4 contact the cable strip to draw power from it. The connector 3 provides at least one conductive shaft 31 connected to the contact 1, so that the contact 1 can be moved when the connector 3 is moved. The connector 3 also has an insulating housing 32 for the user to hold. The end of the conductive shaft 31 furthest from the mounting base 2 is inserted into the housing 32 and fixedly connected thereto. External electrical equipment can be installed at the end of the conductive shaft 31 furthest from the contact 1, allowing power to be transmitted to the equipment via the conductive shaft 31. One end of the conductive shaft 31 passes through the mounting base 2 and is rotatably connected to the contact 1. The conductive shaft 31 and the mounting base 2 are threaded together, allowing the user to rotate the housing 32, causing the conductive shaft 31 to move relative to the mounting base 2 and push the contact 1 to move, thereby using the contact 1 and the conductive metal part 21 to clamp the cable strip.

[0042] In this design, the mounting base 2 is provided with a first anti-rotation structure 23, and the conductive shaft 31 is provided with a second anti-rotation structure 33 that cooperates with the first anti-rotation structure 23 to prevent the conductive shaft 31 from rotating relative to the mounting base 2. That is, through the cooperation of the first and second anti-rotation structures, after the contact member 1 and the mounting base 2 clamp the wire busbar, the rotation of the conductive shaft 31 relative to the mounting base 2 is restricted, thereby preventing the contact member 1 and the mounting base 2 from loosening their clamping of the wire busbar and preventing the generation of electric sparks.

[0043] Specifically, the first anti-rotation structure 23 includes at least one first blocking surface 231. The second anti-rotation structure 33 includes a plurality of second blocking surfaces 331, each second blocking surface 331 being circumferentially distributed on the conductive shaft 31. The first blocking surface 231 and the second blocking surface 331 at least partially overlap to prevent the conductive shaft 31 from rotating in reverse relative to the mounting base 2. Furthermore, the first anti-rotation structure 23 also includes a first clearance surface 232 corresponding to each of the first blocking surface 231, the first clearance surface 232 being inclined relative to the first blocking surface 231. The second anti-rotation structure 33 also includes a second clearance surface 332 corresponding to each of the second blocking surface 331. When the conductive shaft 31 rotates clockwise relative to the mounting base 2, the second clearance surface 332 is located in front of the second blocking surface 331. The second clearance surface 332 and the first clearance surface 232 at least partially overlap to guide the first anti-rotation structure 23 to avoid the conductive shaft 31 when the conductive shaft 31 rotates clockwise relative to the mounting base 2. Thus, by utilizing the cooperation of the first blocking surface 231 and the second blocking surface 331, the reverse rotation of the conductive shaft 31 relative to the mounting base 2 is restricted. By utilizing the cooperation of the first clearance surface 232 and the second clearance surface 332, when the conductive shaft 31 rotates forward relative to the mounting base 2, the first anti-rotation structure 23 can avoid the conductive shaft 31, ensuring that the conductive shaft 31 rotates normally, so that the contact 1 and the mounting base 2 can clamp the wire bar.

[0044] In one alternative, the second anti-rotation structure 33 is integrally formed / fixedly connected to the conductive shaft 31.

[0045] As a specific and feasible implementation of the above solution, the second anti-rotation structure 33 is constructed as a locking member 333, which is a collar-shaped part that is fixedly connected to the conductive shaft 31. A one-way anti-rotation portion 334 is provided on the locking member 333, protruding from the surface of the locking member 333, and a second blocking surface 331 and a second clearance surface 332 are provided on the surface of the one-way anti-rotation portion 334. Correspondingly, the first anti-rotation structure 23 is constructed as an anti-rotation groove 233 formed on the mounting base 2, and the first blocking surface 231 and the second blocking surface 331 are the inner walls of the anti-rotation groove 233 formed on the mounting base 2. The one-way anti-rotation part 334 is embedded in the anti-rotation groove 233. When the conductive shaft 31 rotates in the forward direction, the deformation of the mounting base 2 or the one-way anti-rotation part 334 itself is used to avoid the conductive shaft 31. When the conductive shaft 31 has a tendency to rotate in the reverse direction, the mutual contact between the first blocking surface 231 and the second blocking surface 331 is used to stop the rotation, so that the locking member 333 can only rotate in one direction relative to the mounting base 2.

[0046] As another feasible implementation, the second anti-rotation structure 33 can also be a ratchet 335 fixedly sleeved on the conductive shaft 31, with the second blocking surface 331 and the second clearance surface 332 forming two planes of the ratchet 335, respectively. Correspondingly, the first anti-rotation structure 23 is constructed as a locking tooth 234 with one end hinged to the mounting base 2, and the other end of the locking tooth 234 contacting the ratchet 335. The first blocking surface 231 and the first clearance surface 232 are located at the end of the locking tooth 234 near the ratchet 335. Simultaneously, an elastic metal sheet 24 is fixedly disposed between the locking tooth 234 and the mounting base 2. Thus, when the conductive shaft 31 rotates clockwise, the first clearance surface 232 on the ratchet 335 contacts the second clearance surface 332 on the locking tooth 234, pushing the locking tooth 234 to rotate, thereby achieving the effect of avoiding the conductive shaft 31. The elastic metal sheet 24 allows the first clearance surface 232 to disengage from the second clearance surface 332, which in turn causes the locking tooth 234 to reset, so that the first blocking surface 231 can contact the second blocking surface 331 and restrict the reverse rotation of the conductive shaft 31.

[0047] Because friction occurs between the first anti-rotation structure 23 and the second anti-rotation structure 33 during the clamping process of the wire bar, and the second anti-rotation structure 33 is directly mounted on the conductive shaft 31, a further design specifies that the second anti-rotation structure 33 is made of insulating material to prevent electric sparks from being generated due to friction between the first anti-rotation structure 23 and the second anti-rotation structure 33 when used under high voltage, which could even damage the mounting base 2, thus ensuring safety during use.

[0048] Furthermore, the housing 32 is covered with a soft rubber sleeve 34, which makes it easier for the user to hold and increases the friction between the human hand and the housing 32, making it easier for the housing 32 to rotate with the conductive shaft 31.

[0049] Furthermore, the conductive shaft 31 has a cylindrical portion 311 at one end near the contact member 1. The contact member has a slot 11 at one end near the conductive shaft 31, and the slot 11 has a "T" shaped cross-section. The cylindrical portion 311 is inserted into the slot 11, so that the conductive shaft 31 forms a rotatable connection with the contact member, and the conductive shaft 31 can push the clamping member to slide.

[0050] Example 2

[0051] Reference Figure 8-10 As another optional solution of this application, the difference between this embodiment and Embodiment 1 is that: the second anti-rotation structure 33 is rotatably connected to the conductive shaft 31, and a locking structure is slidably provided on the second anti-rotation structure 33. Simultaneously, a locking part that cooperates with the locking structure is provided on the housing 32. This structure can restrict the rotation of the second anti-rotation structure 33 relative to the housing 32 when the locking part contacts the locking structure. Therefore, by utilizing the cooperation between the locking structure and the locking part, the second anti-rotation structure 33 is synchronously rotated when the housing 32 and the conductive shaft 31 rotate, so that it cooperates with the second anti-rotation structure 33 to restrict the reverse rotation of the conductive shaft 31. Furthermore, in this solution, when the locking structure slides relative to the second anti-rotation structure 33 and disengages from the locking part, the conductive shaft 31 and the housing 32 can rotate relative to the second anti-rotation structure 33. At this time, the housing 32 and the conductive shaft 31 can be reversed, thereby releasing the clamping of the contact 1 and the mounting base 2 on the cable strip. Thus, the emergency live quick-install socket can be removed from the cable strip for use on other cable strips.

[0052] As a specific and feasible implementation of the above solution, the locking structure includes a spacer ring 35 and a slider 36. The spacer ring 35 is sleeved on the conductive shaft 31, and the two are rotatably connected. A groove 351 is provided on the spacer ring 35, and the slider 36 is slidably disposed within the groove 351. An elastic element 361 is fixedly connected to one end of the slider 36 near the groove 351. The elastic element 361 is a spring or elastic metal sheet located between the slider 36 and the spacer ring 35, preferably an elastic metal sheet. A toothed portion 362 is provided at the end of the slider 36 away from the groove 351. The locking portion is a circumferentially distributed toothed groove 321 on the housing 32. Under the elastic force of the elastic element 361, the toothed portion 362 is embedded in the toothed groove 321, thereby restricting the rotation of the locking structure relative to the housing 32, thus preventing the locking structure from rotating with the housing 32. An arc-shaped groove 363 is provided at the end of the slider 36 away from the groove 351, and the toothed part 362 is located outside the arc-shaped groove 363, that is, the toothed part 362 protrudes outside the arc-shaped groove 363.

[0053] In addition, connector 3 also includes a button 37 and an arc-shaped piece 38. The button 37 is slidably mounted on the housing 32, and the arc-shaped piece 38 is fixed to the button 37 and located between the button 37 and the slider 36. The arc-shaped piece 38 is inserted into the arc-shaped groove 363 so that when the button 37 slides relative to the housing 32, it can push the slider 36 to slide relative to the spacer ring 35. Thus, when it is necessary to remove the emergency live quick-install socket from the cable tray, pushing the button 37 causes the arc-shaped piece 38 to move the slider 36, disengaging the toothed portion 362 from the toothed groove. At this time, the housing 32 and the conductive shaft 31 can reverse relative to the second anti-rotation structure 33, thereby releasing the cable tray from the contact member 1 and the mounting base 2. When the button 37 is released, under the elastic force of the elastic member 361, the toothed portion 362 re-engages into the toothed groove, and the housing 32 and the second anti-rotation structure 33 are again prevented from rotating, ready for the next use.

[0054] In a further embodiment, the number of sliders 36 provided on the spacer ring 35 is at least two, and correspondingly, the number of buttons 37 is at least two, so that only when all buttons 37 are pressed at the same time can each slider 36 disengage from the tooth groove, reducing the probability that the housing 32 and the second anti-rotation structure 33 can rotate relative to each other after some buttons 37 are pressed due to misoperation or other reasons, thus causing the wire rack clamping to be unstable.
