Description

Technical Field

[0001] The present invention relates to the field of electric appliances, and particularly to a grounding hanging ring. Background Art

[0002] Before equipment maintenance or other operations, a grounding hanging ring can be used to test for voltage and install a grounding wire, confirm that the transmission line or equipment is without voltage, and prevent accidents caused by voltage or induced voltage. The energy stored in the equipment, such as the electrical energy of a capacitor, can be safely released through the grounding hanging ring, and in three-phase electricity, it can be short-circuited through the grounding hanging ring to prevent power-on during operation;

[0003] Thus, it can be seen that grounding hanging rings are widely used in power lines. After the wiring connector is installed in the current grounding hanging ring, when the grounding ring is hung and taken, if it is subjected to a pulling force in a non-vertical direction, there is a torsional force between the grounding ring and the fixed wiring connector, and it is extremely easy to have a skew displacement. For example, in Chinese Patent: Publication No. CN220439923U, a new type of grounding hanging ring is proposed, which adopts the currently well-known grounding ring fixing method, and realizes fixation by covering it with plastic after contact. When the grounding ring in this case is subjected to a large lateral pulling force, the grounding ring and the insulating protective cover in this case will be displaced, making it difficult to reset;

[0004] At the same time, currently, basically all grounding hanging rings can only perform the fixed movement trajectory of "hooking". In the use environment, power failure situations caused by environmental factors are more common. During emergency repairs, the operation is often at a high altitude, and the wind speed at a relatively high position is also greater than that on the ground. It is often difficult for the operator to "hook" the swaying grounding hanging ring from bottom to top, and due to the long trailing wire of the grounding rod, it is more likely to sway by itself. Under the interaction of the swaying of the grounding rod and the swaying of the grounding hanging ring, if the grounding rod of the operator is not tightened, it is easy to have a situation of excessive swaying and falling off, posing a greater safety hazard. Summary of the Invention

[0005] The purpose of the present invention is to propose a grounding hanging ring in order to solve the problem of insufficient safety of the current grounding hanging ring.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solution: A grounding hanging ring includes an insulating enclosure and a current-carrying wire clamp disposed therein, and a power connection ring frame electrically connected to the current-carrying wire clamp. The current-carrying wire clamp includes a clamp seat and a clamp member for cooperatively fixing a cable. The clamp seat includes a seat body and a lug integrally formed with the seat body, and a positioning hole is provided on the surface of the lug;

[0007] The power connection ring frame includes a conductive ring, the conductive ring includes a ring body and a threaded post for connecting the ring body with a live wire clamp, a clamping cover and two symmetrically installed conductive members are arranged on the ring body, the conductive member includes a movable plate and bumps and contacts arranged thereon, and a tooth groove for positioning the clamping cover is formed on the surface of the movable plate;

[0008] When the power connection ring frame is grounded through a grounding rod, the grounding rod passes through the two conductive members unidirectionally and then jacks up the clamping cover. The clamping cover fits and moves down along the grounding rod and presses the two conductive members under the action of gravity, and the two conductive members are locked to the clamping cover under pressure.

[0009] As a further description of the above technical solution: the insulating sealed bin includes a base and a movable cover arranged on one side thereof, clamping sleeves for clamping wires are symmetrically arranged on both sides of the base and the movable cover, and a buckle for connection is arranged on one side of the base and the movable cover.

[0010] As a further description of the above technical solution: the live wire clamp further includes two mounting screws for cooperating with the threaded post for connection, the clamp seat further includes a power connection groove arranged on the seat body, a sliding groove for limiting the sliding of the frame body is formed on the lug, and a conductive groove for fitting the ring body is formed on the surface of the lug.

[0011] As a further description of the above technical solution: the clamping member includes a clamp body and two offset holes formed on the surface thereof, the threaded posts penetrate and slide through the corresponding offset holes and positioning holes together, and the clamping member further includes deflection portions and pressing portions arranged on both sides of the clamp body.

[0012] As a further description of the above technical solution: the conductive ring further includes through holes symmetrically formed on the ring body for guiding and sliding of the clamping cover, and convex platforms for limiting the deflection angle of the movable plate are arranged on the inner walls of the through holes.

[0013] As a further description of the above technical solution: the clamping cover includes a reinforcing rib for conducting electricity and a protective cover integrally formed with the reinforcing rib, and tooth heads for cooperating with the tooth groove are arranged at both ends of the reinforcing rib.

[0014] As a further description of the above technical solution: the conductive member further includes retaining pins symmetrically arranged on the surface of the movable plate, the two retaining pins are limited to rotate in the through holes, and the movable plate is arranged in a right-angled shape.

[0015] As a further description of the above technical solution: the insulating member includes an insulating sleeve layer arranged on the surface of the ring body, flared insulating ring sleeves are arranged at both ends of the insulating sleeve layer, an opening for partially exposing the ring body and contacting with the conductive groove is formed on the surface of the insulating sleeve layer, and a sliding hole for the tooth head to slide is formed on the surface of the flared insulating ring sleeve.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] In this solution, through the setting of two conductive parts and a clamping cover, by directly placing the grounding rod on its shaking trajectory, or directly pushing the grounding rod upward against the contact head from the bottom, and deflecting the conductive part through a clamping pin until the grounding rod passes through the conductive part and lifts the clamping cover. When the grounding rod passes through the conductive part, it resets under the action of gravity, enabling the grounding rod to only pass through the two conductive parts unidirectionally. At this time, the convex points on the surfaces of the two conductive parts contact on one side of the through hole. When the grounding rod is pulled downward, the convex points of the conductive part are snapped into the through hole, and through the tooth groove, it is snapped into one side of the clamping cover that fits against the top of the grounding rod, locking the clamping cover and pressing the grounding rod against the surfaces of the two conductive parts at the same time. This method not only can be installed through a direct "pushing" linear trajectory compared to the traditional connection method of directly "hooking" the trajectory, making it more convenient and fast to connect in a complex environment, facilitating the grounding operation from bottom to top, but also, under the action of the gravity of the grounding rod and the grounding wire it drags, the greater the length of the grounding wire, the greater the gravity, and the greater the locking force of the conductive part on the clamping cover, enabling this solution to lock itself according to the gravity of the grounding rod itself, greatly avoiding the risk of falling caused by the grounding rod not being clamped tightly itself, and greatly reducing the shaking amplitude, ensuring the safety of use.

[0018] At the same time, the clamping cover can always keep the top of the power connection area covered, playing a very good protective role, greatly improving the safety. And the clamping cover itself can conduct electricity, meeting the use method of directly hanging and fixing the grounding rod in the traditional way, greatly improving the overall applicability, and having a certain optimization in safety compared to the traditional way where the power connection area is directly exposed.

[0019] In this solution, during the casting process of the ring body, two threaded columns are integrally formed on it, making it have high rigidity. And the threaded columns pass through the positioning holes on the surface of the lug. During installation, through the cooperation of the installation screw above the clamp body and the threaded column, the clamp body is pressed and deflected to clamp the exposed area of the cable in the power connection groove. As the installation screw is tightened, the ring body and the clamp body are located on both sides of the clamp seat and clamp towards each other. At this time, the clamp body tightly presses the cable in the power connection groove of the clamp seat, and at the same time, the ring body closely fits in the conductive groove, realizing the electrical connection as a whole. And with the cooperation of the conductive column in the positioning hole, under the action of the lateral force, it can maintain stable support and will not be misaligned. Compared with the traditional fixing method of covering the surface with plastic, it has higher structural strength. Brief Description of the Drawings

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] As Figures 1 - 10As shown, the present invention provides: a grounding hanging ring, including an insulating sealing compartment 10 and a live wire clamp 20 arranged therein, and a live wire ring frame 30 electrically connected to the live wire clamp 20, the live wire clamp 20 includes a clamp seat 21 and a clamp 22 for fixing the cable therewith, the clamp seat 21 includes a seat body 211 and a lug 212 integrally formed with the seat body 211, and a positioning hole 213 is opened on the surface of the lug 212;

[0033] The positioning hole 213 is formed on the surface of the lug 212 . When the threaded column 312 passes through, the conductive ring 31 and the clamping seat 21 can form a stable structure to avoid misalignment.

[0034] The power connection ring frame 30 includes a conductive ring 31, which includes a ring body 311 and a threaded column 312 used to connect the ring body 311 with the power supply clamp 20. The ring body 311 is provided with a card cover 33 and two symmetrically installed conductive members 32. The conductive member 32 includes a movable plate 321 and a convex point 325 and a contact 323 arranged thereon. The surface of the movable plate 321 is provided with a tooth groove 324 for positioning the card cover 33.

[0035] The contact 323 can play a role of balancing the movable plate 321 , and under the action of gravity, the protrusion 325 is always kept at one side of the through hole 313 .

[0036] The threaded column 312 is integrally formed with the ring body 311 and has a high structural strength. The protrusion 325 on the surface of the movable plate 321 can cooperate with the through hole 313 to limit the position. When the movable plate 321 is subjected to a large reaction force from the grounding rod, the protrusion 325 can be clamped into the through hole 313 to achieve limiting. At this time, the movable plate 321 can clamp and position the card cover 33 through the tooth groove 324. At the same time, when the grounding rod is removed, the card cover 33 is lifted up and slid, so that the card cover 33 can slide out of the tooth groove 324 through the tooth heads 332 on both sides and push the protrusion 325 on the surface of the movable plate 321 out of the through hole 313.

[0037] When the power ring frame 30 is grounded through the grounding rod, the grounding rod passes through the two conductive members 32 in one direction and lifts the card cover 33. The card cover 33 moves down in contact with the grounding rod and presses the two conductive members 32 under the action of gravity. The two conductive members 32 are pressed to lock the card cover 33.

[0038] Specifically, Figure 1 As shown: the insulating sealing compartment 10 includes a base 11 and a movable cover 12 arranged on one side thereof, both sides of the base 11 and the movable cover 12 are symmetrically provided with wire clamping sleeves 13, and one side of the base 11 and the movable cover 12 is provided with a buckle for connection.

[0039] By providing the movable cover 12 , the movable cover 12 can move on one side of the base 11 , and the movable cover 12 is integrally injection-molded with the base 11 , and can be closed and sealed in cooperation with the buckle on the other side.

[0040] Specifically, as Figure 10 shown: The current-carrying wire clamp 20 further includes two mounting screws 23 for cooperating with the threaded posts 312. The clamp base 21 further includes a power connection groove 216 provided on the base body 211. A sliding groove 214 for limiting the sliding of the frame body is provided on the lug 212, and a conductive groove 215 for fitting the ring body 311 is provided on the surface of the lug 212.

[0041] The lug 212 of the clamp base 21 serves as an extended area, and the conductive groove 215 on its surface can stably fit the ring body 311 in the area of the lug 212.

[0042] Specifically, as Figure 5 shown: The clip 22 includes a clip body 221 and two offset holes 222 provided on its surface. The threaded posts 312 penetrate and slide together in the corresponding offset holes 222 and positioning holes 213. The clip 22 further includes deflection portions 223 and pressing portions 224 provided on both sides of the clip body 221.

[0043] The deflection portion 223 of the clip 22 can slide in the sliding groove 214, and when sliding, the inclination angle of the clip 22 can change, and the cable is fixed and energized through the pressing portion 224 cooperating with the power connection groove 216 of the clamp base 21. Among them, the offset holes 222 can ensure that the threaded posts 312 can pass through under different angular deflection states of the clip 22, and this method can adapt to the fixation of cables with different diameters.

[0044] Specifically, as Figure 4 shown: The conductive ring 31 further includes through holes 313 symmetrically provided on the ring body 311 for guiding the sliding of the cover 33. The inner wall of the through hole 313 is provided with a boss 314 for limiting the deflection angle of the movable plate 321.

[0045] The through holes 313 are provided on the conductive ring 31, and can stably guide the movement of the cover 33 inside. At the same time, the boss 314 provided in the through hole 313 can limit the deflection angle of the movable plate 321, and the movable plate 321 can support the grounding rod based on the limiting effect of the boss 314.

[0046] Specifically, as Figure 9 shown: The cover 33 includes a reinforcing rib 331 for conducting electricity and a cover 333 integrally formed with the reinforcing rib 331. Tooth heads 332 for cooperating with the tooth grooves 324 are provided at both ends of the reinforcing rib 331.

[0047] The top and bottom of the cover 33 are both inclined towards the middle, which can play a certain guiding role for the grounding rod.

[0048] Specifically, as Figure 8As shown in the figure: The conductive member 32 further includes pin shafts 322 symmetrically arranged on the surface of the movable plate 321. The two pin shafts 322 are rotationally limited within the through hole 313, and the movable plate 321 is arranged in a right-angled shape.

[0049] By providing the conductive member 32 which is arranged in a right-angled shape, it can lock the card cover 33 when deflected, and the pin shafts 322 on the surface can maintain its movable connection to the inner wall of the through hole 313.

[0050] Specifically, as Figure 10 As shown in the figure: The insulating member 40 includes an insulating sleeve layer 41 arranged on the surface of the ring body 311. Flared insulating ring sleeves 43 are arranged at both ends of the insulating sleeve layer 41. An opening 42 for partial exposure of the ring body 311 and contact with the conductive groove 215 is provided on the surface of the insulating sleeve layer 41. A sliding hole 44 for the sliding of the tooth head 332 is provided on the surface of the flared insulating ring sleeve 43.

[0051] By providing the insulating member 40, the insulating member 40 can wrap the ring body 311 to keep it in a protected state, reducing the risk of electric leakage. Its insulating sleeve layer 41 closely adheres to the surface of the ring body 311 to maintain insulation closure, and can maintain insulation during plastic injection molding with the base 11. The reserved opening 42 on its surface can meet the contact between the ring body 311 and the conductive groove 215. At the same time, in this solution, the flared insulating ring sleeves 43 on both sides of the insulating sleeve layer 41 can reserve a certain space to meet the need for the deflection angle of the conductive member 32, protect the conductive member 32 during deflection, avoid situations such as accidental touch, and improve the safety of use.

[0052] A sliding hole 44 is provided on one side of the flared insulating ring sleeve 43, which can reserve a space for the sliding of the tooth head 332 of the card cover 33. Since the aperture is small, the sliding hole 44 is located inside and is directly connected to the through hole 313 without direct exposure risk.

[0053] Furthermore, the card cover 33 protects the contact head 323 to improve its protection effect.

[0054] In the installation of this solution, by partially peeling the insulating layer on the surface of the cable, then placing the cable into the power connection groove 216 on the seat body 211, then placing the pressing part 224 of the clamping body 221 on the surface of the cable, and cooperating the installation screw 23 with the threaded post 312 to press down and deflect the seat body 211 to clamp the cable. Finally, cooperate the movable cover 12 with the base 11 to close, and fit the cable clamping sleeve 13 on the surface of the cable to complete the installation;

[0055] This method is easy to install, has a solid structure, is not easy to deflect, and has relatively stable performance for a long time. The outer plastic coating only plays a protective role and does not serve as a support. The internal mounting screws 23 and threaded columns 312 are clamped to bear the force. The overall force is applied by metal, which has high strength and is reliable to use.

[0056] When in use, the grounding rod is directly placed under the two contacts 323, and then the grounding rod is directly pressed against the contacts 323 from bottom to top. At this time, the pin 322 on the surface of the conductive member 32 is deflected, and the grounding rod passes through the deflected conductive member 32 and then pushes up the cover 33. After the grounding rod passes through the conductive member 32, the conductive member 32 is reset under the action of gravity. At this time, the grounding rod passes through the two conductive members 32 in one direction. After the two conductive members 32 are reset, the protrusion 325 on the surface of the grounding rod contacts one side of the through hole 313. side (at this time, the tooth groove 324 cannot lock the tooth head 332), when the ground rod is pulled downward, the conductive member 32 blocks the ground rod, and under pressure, the protrusion 325 of the conductive member 32 is inserted into the through hole 313, and the tooth groove 324 is inserted into one side of the card cover 33, and the tooth head 332 of the card cover 33 is in a meshing state with the tooth groove 324, and the card cover 33 is always attached to the top of the ground rod under the action of gravity, so that the card cover 33 is locked and the ground rod is limited to the surface of the two conductive members 32, so as to achieve self-locking;

[0057] This method realizes self-locking stability under the action of gravity of the grounding rod and the grounding wire dragged on its surface, can avoid large shaking under pressure, prevent detachment, and can make up for the defects of clamping and tightening of the traditional grounding rod. It can play a role of insurance when the grounding rod is not fully tightened. Combined with the tightening effect of the traditional grounding rod, the two contacts 323 can be clamped to improve stability.

[0058] When releasing, the grounding rod is directly lifted upward to make the conductive member 32 lose pressure, and the cover 33 has a lifting force to press the tooth head 332 out of the tooth groove 324, and the protrusions 325 of the two conductive members 32 slide out of the through hole 313, and the grounding rod can be removed.

[0059] As can be seen from the above, the removal operation of this solution is no different from the traditional one, and the operation is simple and quick.

[0060] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
