Abstract
Description
Technical Field
[0001] The present application relates to the field of power connection devices, and in particular to a live access emergency power supply socket. Background Art
[0002] A substation is a location within a power system that transforms voltage and current, receives, and distributes electrical energy. A substation within a power plant is a step-up substation, whose function is to boost the voltage of electricity generated by the generator and feed it into the high-voltage grid. During daily use, substations and high-voltage cabinets or substations require inspection and maintenance, requiring connections via external connectors.
[0003] The structure of the emergency connector for high-voltage cabinets, substations, and substations is similar to the clamping section structure of a connector disclosed in Chinese patent document CN214280220U. During use, an external force controls the rotation of a conductive screw, causing the first conductive axis to approach the second conductive axis, thereby bringing the first conductive contact finger and the second conductive contact finger closer together. This allows external testing and maintenance equipment requiring power to be electrically connected to the conductive screw, thereby drawing power from the high-voltage cabinet, substation, or substation.
[0004] During use, it was discovered that in the above structure, the conductive screw needs to be rotated multiple times to clamp the wire bank between the first conductive contact finger and the second conductive contact finger, which makes the operation inconvenient. In addition, during the power supply process and the process of connecting external electrical equipment to the connector, the conductive screw can still rotate, thereby causing the first conductive contact finger to move away from the second conductive contact finger, resulting in an unstable connection between the connector and the high-voltage cabinet, substation, or transformer. Due to working in a high-voltage environment, the unstable connection not only makes detection and maintenance inconvenient, but also may generate electric sparks between the conductive contact fingers and the wire bank, posing a safety hazard.
[0005] Currently, there is no live access emergency power socket that is easy to use and has a stable connection. Summary of the Invention

[0035] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.
[0036] Reference Figure 1-3A live emergency power supply socket includes: a contact 1, a mounting seat 2, a connector 3, and a one-way stop 4. The contact 1 is used to contact the wire bank to draw power from the wire bank. The mounting seat 2 is used to mount the contact 1 and provide space for the contact 1 to slide relative to the mounting seat 2. Specifically, the mounting seat 2 is a shell made of an insulating material, and a conductive metal part is fixedly arranged in the mounting seat 2. The conductive metal part has a movable groove 21, and one side of the movable groove 21 is open to allow the wire bank to be inserted. The area where the movable groove 21 is located is the space for the contact 1 to slide relative to the mounting seat 2. When the wire bank is inserted into the movable groove 21, the contact 1 slides in the movable groove 21, clamping the wire bank between the conductive metal part and the contact 1. Conductive contact fingers 5 are fixedly arranged on the contact 1 and the surface of the conductive metal part that contacts the wire bank. The two conductive contact fingers 5 contact the wire bank to draw power from the wire bank. The connector 3 is used to provide at least one conductive shaft 31 connected to the contact 1 so that the contact 1 can be pushed to move when the connector 3 is moved. The connector 3 also has an insulating housing 32, which is fixed outside the conductive shaft 31 for easy gripping by the user. External electrical equipment can be mounted on the end of the conductive shaft 31 away from the contact 1, and the conductive shaft 31 is used to transmit power to the electrical equipment.
[0037] In this embodiment, the connector 3 is slidably connected to the mounting base 2 to drive the contact 1 to move when the connector 3 slides in a first direction. The first direction here is parallel to the direction in which the contact 1 slides relative to the mounting base 2. By sliding the connector 3, the conductive shaft 31 can be used to directly push the contact 1 to move and clamp the wire bank. A one-way stopper 4 is provided on the mounting base 2 and has a first stopper structure. At the same time, a second stopper structure is provided on the conductive shaft 31 to cooperate with the first stopper structure to prevent the conductive shaft 31 from sliding relative to the mounting base 2 in the opposite direction of the first direction. That is, through the cooperation of the first stopper structure and the second stopper structure, after the contact 1 and the mounting base 2 clamp the wire bank, the conductive shaft 31 can be restricted from sliding relative to the mounting base 2, thereby preventing the contact 1 and the mounting base 2 from loosening their grip on the wire bank and ensuring the stability of power supply.
[0038] As one of the specific feasible solutions of the above scheme, the first stopping structure is a slider 41 with oblique teeth, and the second stopping structure is a cylinder 33 fixedly mounted on the conductive shaft 31, and the cylinder 33 is provided with a tooth-shaped groove along its length. The slider 41 has a side with oblique teeth that can be embedded in the tooth-shaped groove. Specifically, the slider 41 includes at least one first blocking surface 411, and each first blocking surface 411 is arranged perpendicular to the first direction. The tooth-shaped groove includes a plurality of second blocking surfaces 331. The first blocking surface 411 and the second blocking surface 331 at least partially overlap, so that after the contact member 1 and the mounting seat 2 clamp the fixed wire row, the first blocking surface 411 is located behind the second blocking surface 331 along the first direction. The cooperation between the two prevents the conductive shaft 31 from sliding relative to the mounting seat 2 in the opposite direction of the first direction, thereby preventing the contact member 1 from loosening and achieving the purpose of stably installing the live emergency power supply socket on the wire row.
[0039] Compatible with the above solution, to ensure that the first stop structure does not hinder the movement of the contact member 1 during its sliding and clamping of the wire array with the mounting seat 2, the one-way stop member 4 is slidably mounted on the mounting seat 2, allowing the slider 41 to disengage from the conductive shaft 31 as the one-way stop member 4 moves. Simultaneously, the side of the slider 41 having the helical teeth also includes a first avoidance surface 412 corresponding one-to-one with the first blocking surface 411. The first avoidance surface 412 is arranged obliquely relative to the first blocking surface 411 and is located rearward of the first blocking surface 411 along the first direction. The first avoidance surface 412 contacts the second stop structure. When the conductive shaft 31 slides relative to the mounting seat 2, the conductive shaft 31 can slide relative to the first avoidance surface 412 and guide the one-way stop member 4 to slide relative to the mounting seat 2, thereby causing the first stop structure to avoid the conductive shaft 31 and ensuring smooth movement of the conductive shaft 31. Specifically, the toothed groove also includes a second avoidance surface 332 corresponding one-to-one with the second blocking surface 331. The second relief surface 332 is located behind the second blocking surface 331 along the first direction, and the second relief surface 332 at least partially overlaps with the first relief surface 412. Specifically, when the conductive shaft 31 slides relative to the mounting base 2 in the first direction, the first relief surface 412 slides relative to the second relief surface 332. During this process, the second relief surface 332 generates a component force on the slider 41 along the sliding direction of the one-way stop 4, thereby pushing the one-way stop 4 to slide and avoid the conductive shaft 31.
[0040] In a further embodiment, a slide groove 22 is provided on the mounting base 2, and the one-way stop member 4 is slidably arranged in the slide groove 22. The one-way stop member 4 includes an elastic connecting portion 42. The elastic connecting portion 42 is connected between the inner wall of the slide groove 22 and the first stop structure to guide the one-way stop member 4 to reset after the one-way stop member 4 avoids the conductive shaft 31. Specifically, the elastic connecting portion 42 is constructed as an elastic metal sheet with one end fixed to the first stop structure. The elastic metal sheet is located in the slide groove 22, and its end away from the first stop structure abuts against the inner wall of the slide groove 22, so that the elastic metal sheet can use its elastic force to completely separate the first avoidance surface 412 of the first stop structure from the second avoidance surface 332 of the second stop structure, and then push the first stop structure to slide and reset, so that the first blocking surface 411 can partially overlap with the second blocking surface 331 again. As a result, when the conductive shaft 31 pushes the contact 1 to move and, together with the mounting base 2, clamp the cable bus, the elastic connector 42 causes the first blocking surface 411 to partially overlap with the second blocking surface 331, preventing the contact 1 from loosening. This arrangement allows the power extraction device to be adaptably installed on cable busses of various specifications. Alternatively, the elastic connector 42 can be a spring, torsion spring, or other equivalent component that can replace the elastic metal sheet. This should not be considered a limitation to the implementation of this solution.
[0041] In the above solution, to ensure stable clamping of the wire bank by the contact member 1 and the mounting base 2, the contact area between the first and second stop structures must be able to withstand sufficient load. To this end, in a more specific embodiment, both the slider 41 (the first stop structure) and the cylinder 33 (the second stop structure) are made of metal to ensure their load-bearing capacity.
[0042] Since the slider 41 and the cylinder 33 have a relative sliding relationship, if the two directly contact the conductive shaft 31, they will be powered on. At this time, the relative sliding between the two is likely to cause safety risks. For this reason, in a further solution, the conductive shaft 31 includes: a fixing member 34 and an insulating sleeve 35. Among them, the fixing member 34 is fixedly arranged on the connector 3, that is, the fixing member 34 is fixed inside the shell 32, and a core shaft 36 is provided at one end close to the mounting seat 2. The core shaft 36 is connected to the contact member 1 at one end away from the fixing member 34. The core shaft 36 and the fixing member 34 are both made of conductive materials to transmit electricity. External electrical equipment is connected to the end of the fixing member 34 away from the core shaft 36 and draws electricity. The insulating sleeve 35 is sleeved on the outside of the core shaft 36, and one end of it is fixed to the fixing member 34. The second stopper structure is fixedly mounted outside the insulating sleeve 35. Specifically, the barrel 33 is sheathed outside the insulating sleeve 35, isolated from the fixing member 34 and the core shaft 36. This prevents the barrel 33 and the slider 41 from becoming electrically charged, ensuring safe operation. Furthermore, an insulating ring 6 is also provided at the contact area between the conductive metal member on the mounting base 2 and the conductive shaft 31 to prevent the barrel 33 from becoming electrically charged due to contact with the conductive metal member.
[0043] In all the aforementioned solutions, since the contact member 1 and the mounting seat 2 cannot move after clamping the wire bank, relative sliding may still occur between the wire bank and the contact member 1, resulting in unstable connection between the power supply device and the wire bank. To solve this problem, in a further solution, a through-hole 341 is provided on the fixing member 34. A sliding portion 361 is provided at one end of the core shaft 36, and the sliding portion 361 is slidably arranged in the through-hole 341, so that a sliding connection is formed between the core shaft 36 and the fixing member 34. The end of the insulating sleeve 35 is blocked outside the through-hole 341 to limit the sliding portion 361 from moving out of the through-hole 341 and prevent the core shaft 36 from detaching from the fixing member 34. The conductive shaft 31 also includes: a clamping spring 37. The clamping spring 37 is located in the through-hole 341, one end of which abuts against the sliding portion 361, and the other end abuts against the inner wall of the through-hole 341. In this way, after both the contact 1 and the mounting base 2 contact the wire bank, the connector 3 can continue to move, causing the sliding portion 361 to slide within the through-hole 341, thereby compressing the compression spring 37. After the connector 3 stops moving, the first and second stop structures cooperate to restrict the movement of the fixing member 34, which is fixedly connected to the insulating sleeve 35. The compression spring 37 will remain compressed and apply pressure to the core shaft 36, increasing the pressure of the contact 1 on the wire bank. This arrangement increases the pressure of the contact 1 on the wire bank, thereby strengthening the connection strength between the wire bank and the power supply device.
[0044] In a further embodiment, the conductive shaft 31 further includes an insulating sheet 38. The insulating sheet 38 is located within the through-hole 341, fixedly connected to the fixing member 34, and spaced apart from the sliding portion 361. The provision of the insulating sheet 38 prevents the core shaft 36 from sliding relative to the through-hole 341, thereby preventing sparks from forming between the inner wall of the through-hole 341 and the sliding portion 361 when the sliding portion 361 approaches the inner wall of the through-hole 341, thereby further improving safety in use.
