Description

Technical Field

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

[0002] Before equipment maintenance or other operations, the grounding ring can be used to test electricity and install grounding wires to confirm that there is no voltage in the transmission line or equipment to prevent accidents caused by voltage or induced voltage. The energy stored in the equipment, such as the electric energy of the capacitor, can be safely released through the grounding ring, and the three-phase electricity can be short-circuited through the grounding ring to prevent power from being turned on during operation; It can be seen that the grounding ring is widely used in power lines. After the current grounding ring is installed on the connector, if the grounding ring is subjected to a pulling force in a non-vertical direction after being hung, there will be a torsional force between the grounding ring and the connector in a fixed state, which is very likely to cause deflection and displacement. For example, Chinese patent: Announcement No. CN220439923U proposes a new grounding ring, which adopts the currently well-known grounding ring fixing method, which is fixed by covering it with plastic after contact. In this method, when the grounding ring is subjected to a large lateral pulling force, the grounding ring and the insulating protective cover in the case will be displaced, making it difficult to reset; At the same time, the current grounding rings can basically only move in a fixed trajectory of "hooking". In the use environment, power failures caused by environmental factors are more common, so that during the emergency repair process, the work is often done at high altitudes, and the wind speed at higher positions is also greater than that on the ground. It is often difficult for operators to "hook" the shaking grounding ring from bottom to top, and the grounding rod is based on a longer drag line, so it is more prone to shaking. Under the interaction of this shaking and the shaking of the grounding ring, if the operator's grounding rod is not tightened, it is easy to fall off due to excessive shaking, etc., posing a major safety hazard. Summary of the invention

[0003] The purpose of the present invention is to solve the problem of insufficient safety of the current grounding ring and to propose a grounding ring.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a grounding hanging ring, comprising an insulating sealing compartment and a live wire clamp arranged therein, and a live wire ring frame electrically connected to the live wire clamp, the live wire clamp comprising a clamp seat and a clamp for fixing the cable therewith, the clamp seat comprising a seat body and a lug integrally formed with the seat body, and a positioning hole is opened on the surface of the lug; The power connection ring frame includes a conductive ring, the conductive ring includes a ring body and a threaded column for connecting the ring body with the power supply clamp, the ring body is provided with a card cover and two symmetrically installed conductive members, the conductive members include a movable plate and a convex point and a contact arranged thereon, and the surface of the movable plate is provided with a tooth groove for positioning the card cover; When the power ring frame is grounded through the grounding rod, the grounding rod passes through two conductive parts in one direction and then lifts the card cover. The card cover moves down in contact with the grounding rod and presses the two conductive parts under the action of gravity. The two conductive parts are pressed and locked to the card cover.

[0005] As a further description of the above technical solution: the insulating sealing compartment includes a base and a movable cover arranged on one side thereof, both sides of the base and the movable cover are symmetrically provided with wire clamping sleeves, and one side of the base and the movable cover is provided with a buckle for connection.

[0006] As a further description of the above technical solution: the power supply clamp also includes two mounting screws for cooperating with the threaded column connection, the clamp seat also includes a power connection groove arranged on the seat body, the lug is provided with a sliding groove for limiting the sliding of the frame body, and the surface of the lug is provided with a conductive groove for fitting the ring body.

[0007] As a further description of the above technical solution: the clamp includes a clamp body and two offset holes opened on its surface, the threaded columns slide through the corresponding offset holes and positioning holes, and the clamp also includes a deflection part and a holding part arranged on both sides of the clamp body.

[0008] As a further description of the above technical solution: the conductive ring also includes a through hole symmetrically opened on the ring body for guiding the sliding of the card cover, and the inner wall of the through hole is provided with a boss for limiting the deflection angle of the movable plate.

[0009] As a further description of the above technical solution: the card cover includes a reinforcing rib for conducting electricity and a shield integrally formed with the reinforcing rib, and tooth heads matching with the tooth grooves are arranged at both ends of the reinforcing rib.

[0010] As a further description of the above technical solution: the conductive member also includes latches symmetrically arranged on the surface of the movable plate, the two latches are located in the through holes to limit rotation, and the movable plate is arranged at a right angle.

[0011] As a further description of the above technical solution: the insulating part includes an insulating sleeve layer arranged on the surface of the ring body, and flared insulating ring sleeves are arranged at both ends of the insulating sleeve layer. The surface of the insulating sleeve layer is provided with an opening for partially exposing the ring body and contacting the conductive groove, and the surface of the flared insulating ring sleeve is provided with a sliding hole for the tooth head to slide.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: This solution is provided with two conductive parts and a card cover. By directly placing the grounding rod on its shaking track, or directly pressing the grounding rod against the contact from bottom to top, and deflecting the conductive part through the card pin, until the grounding rod passes through the conductive part and lifts up the card cover. After the grounding rod passes through the conductive part, it is reset under the action of gravity, so that the grounding rod can only pass through the two conductive parts in one direction. At this time, the convex points on the surfaces of the two conductive parts are in contact with one side of the through hole. When the grounding rod is pulled downward, the convex points of the conductive part are inserted into the through hole, and are inserted into the side of the card cover that fits the top of the grounding rod through the tooth groove, so that the card cover is locked and the grounding rod is pressed on the surfaces of the two conductive parts at the same time. Compared with the traditional connection method of directly "hooking" the track, this method can not only be installed by directly "pushing" the straight track, so that it can be connected more conveniently and quickly in complex environments, and is convenient for bottom-up grounding operations. In addition, under the action of the gravity of the grounding rod and the grounding wire dragged by it, the longer the grounding wire is, the greater the gravity is, and the greater the locking force of the conductive part on the card cover is, so that this scheme can lock the grounding rod according to its own gravity, realize self-locking after installation, can greatly avoid the risk of falling off caused by the grounding rod itself not being clamped, and can greatly reduce the amplitude of shaking, to ensure safety in use.

[0013] At the same time, the card cover can always keep the top of the power connection area covered, which has a good protective effect and greatly improves safety. The card cover itself is conductive and can meet the traditional method of directly hanging and fixing the grounding rod. The overall applicability is greatly improved, and the safety is optimized compared to the traditional method of directly exposing the power connection area.

[0014] In this solution, two threaded columns are integrally formed on the ring body during the casting process, so that it has high rigidity, and the threaded columns pass through the positioning holes on the surface of the lug. During installation, the mounting screws on the top of the clamp body cooperate with the threaded columns to press the clamp body and deflect it to clamp the exposed area of ​​the cable in the power connection groove. As the mounting screws are tightened, the ring body and the clamp body are located on both sides of the clamp seat and clamped toward each other. At this time, the clamp body presses the cable tightly in the power connection groove of the clamp seat, and the ring body fits tightly in the conductive groove, so that the overall electrical connection is achieved. The conductive column is located in the positioning hole and is subjected to lateral force. It can maintain stable support without dislocation. Compared with the traditional surface-coated plastic fixing method, it has higher structural strength. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1-Figure 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; 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.

[0028] 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. 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 .

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] Specifically, Fig.10 As shown: the power clamp 20 also includes two mounting screws 23 for matching with the threaded column 312, the clamp seat 21 also includes a power connection groove 216 set on the seat body 211, the lug 212 is provided with a slide groove 214 for limiting the sliding of the frame, and the surface of the lug 212 is provided with a conductive groove 215 for fitting the ring body 311.

[0034] The lug 212 of the clamping seat 21 serves as an extended area, and the conductive groove 215 on the surface thereof can achieve stable fitting with the ring body 311 in the lug 212 area.

[0035] Specifically, Figure 5 As shown: the clamp 22 includes a clamp body 221 and two offset holes 222 opened on its surface, the threaded column 312 slides through the corresponding offset holes 222 and the positioning hole 213, and the clamp 22 also includes a deflection part 223 and a holding part 224 arranged on both sides of the clamp body 221.

[0036] The deflection portion 223 of the clamp 22 can slide in the slide groove 214, and when sliding, the inclination angle of the clamp 22 can change, and the cable can be fixed and energized by cooperating with the power connection groove 216 of the clamp seat 21 through the pressing portion 224, wherein the offset hole 222 can satisfy the requirement that the threaded column 312 can be kept passing through when the clamp 22 is deflected at different angles, and this method can adapt to the fixing of cables of different diameters.

[0037] Specifically, Figure 4 As shown, the conductive ring 31 also includes a through hole 313 symmetrically provided on the ring body 311 for guiding the sliding of the card cover 33, and the inner wall of the through hole 313 is provided with a boss 314 for limiting the deflection angle of the movable plate 321.

[0038] The through hole 313 is opened on the conductive ring 31 , and the movement of the card cover 33 can be stably guided therein. Meanwhile, the boss 314 arranged in the through hole 313 can limit the deflection angle of the movable plate 321 . The movable plate 321 can support the grounding rod based on the limiting effect of the boss 314 .

[0039] Specifically, Fig. 9 As shown, the card cover 33 includes a reinforcing rib 331 for conducting electricity and a shield 333 integrally formed with the reinforcing rib 331 , and tooth heads 332 matching with the tooth grooves 324 are provided at both ends of the reinforcing rib 331 .

[0040] The top and bottom of the card cover 33 are both inclined toward the middle, which can play a certain guiding role on the grounding rod. Specifically, Figure 8As shown, the conductive member 32 further includes latches 322 symmetrically arranged on the surface of the movable plate 321 , the two latches 322 are located in the through holes 313 to limit rotation, and the movable plate 321 is arranged at a right angle.

[0041] By providing the conductive member 32 , the conductive member 32 is provided at a right angle so as to lock the card cover 33 when deflected, and the card pin 322 on the surface can maintain its active connection with the inner wall of the through hole 313 .

[0042] Specifically, Fig.10 As shown: the insulating member 40 includes an insulating sleeve layer 41 disposed on the surface of the ring body 311, and flared insulating ring sleeves 43 are disposed at both ends of the insulating sleeve layer 41. An opening 42 is provided on the surface of the insulating sleeve layer 41 for partially exposing the ring body 311 and contacting with the conductive groove 215, and a sliding hole 44 is provided on the surface of the flared insulating ring sleeve 43 for the tooth head 332 to slide.

[0043] By setting the insulating member 40, the insulating member 40 can cover the ring body 311 to keep it in a protected state and reduce the risk of leakage. The insulating sleeve 41 is tightly attached to the surface of the ring body 311 to maintain insulation closure and to maintain insulation with the base 11 during plastic injection molding. The opening 42 reserved on the surface can meet the contact between the ring body 311 and the conductive groove 215. At the same time, the present solution can reserve a certain space through the expanded insulating ring sleeves 43 on both sides of the insulating sleeve 41 to meet the deflection angle requirements of the conductive member 32, protect the conductive member 32 while deflecting, avoid accidental touch and the like, and improve the safety of use.

[0044] A sliding hole 44 is provided on one side of the expanded insulating ring sleeve 43 to reserve a space for the tooth head 332 of the card cover 33 to slide. Due to its small diameter, the sliding hole 44 is located on the inside and directly connected to the through hole 313 without direct exposure risk.

[0045] Furthermore, the card cover 33 protects the contact 323, thereby improving the protection effect.

[0046] During installation, the present solution is to partially peel off the insulating layer on the surface of the cable, then place the cable in the power connection slot 216 on the seat 211, then place the pressing portion 224 of the clamp 221 on the surface of the cable, and press the seat 211 with the mounting screw 23 and the threaded column 312 to deflect the cable, and finally close the movable cover 12 with the base 11, and fit the wire clamp 13 on the surface of the cable to complete the installation; 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.

[0047] 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; 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.

[0048] 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.

[0049] 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.

[0050] 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.
