Description
Technical Field
[0001] This invention relates to the field of power technology, and more specifically, to a user-friendly power connection detector assembly. Background Technology
[0002] Grounding rings serve as protective devices to prevent overhead insulated conductors from being broken by lightning, and are also used for voltage testing and temporary grounding during maintenance and construction. To facilitate wiring for voltage testing, one end of existing grounding rings is often left exposed. This poses a risk of electric shock when connecting a grounding wire voltage tester to the ring; furthermore, the exposed grounding ring allows unauthorized individuals to tap into the power lines, potentially damaging transmission lines.
[0003] Chinese Patent Publication No. CN209607932U, published on November 8, 2019, discloses an invention entitled "A Grounding Wire Voltage Detector." While the device facilitates voltage detection by using a connecting hook to easily engage with a grounding ring, it suffers from the following drawback: because the connecting hook is made of metal, improper operation can easily lead to the risk of electric shock. Summary of the Invention
[0004] The present invention overcomes the following shortcomings in the prior art: (1) the exposed grounding test ring makes it easy to cause electric shock during the test process; (2) the exposed grounding test ring makes it easy for illegal personnel to connect to the power supply, which can easily cause damage to the power transmission line. The present invention provides a convenient power connection tester assembly that can replace the grounding test ring in the prior art and effectively prevent the electric shock hazard that occurs when connecting to the power supply; at the same time, it has no exposed conductive parts, which can effectively prevent illegal personnel from connecting to the power supply and prevent damage to the power transmission line.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a convenient-to-use electrical detector assembly, comprising: The voltage testing clamp has a clamping jaw at one end and a connecting cylinder at the other end. A connecting block with a first connecting hole is located near the connecting cylinder. A groove on the connecting cylinder mates with the connecting block, and second connecting holes on both sides of the groove. A rotating shaft passes through the first and second connecting holes. A sealing ring is placed between the facing surfaces of the groove and the connecting block, and the sealing ring is fitted around the rotating shaft. A voltage testing connection hole is located inside the connecting cylinder. The voltage testing clamp is made of insulating material. A conductive component is disposed inside a voltage testing clamp, comprising a first conductor disposed inside the clamp opening and a second conductor disposed inside a voltage testing connection hole, wherein the first conductor and the second conductor are connected by a conductive wire; A voltage tester, one end of which is equipped with a voltage test head that mates with a voltage test connection hole.
[0006] This invention pre-fixes the voltage testing clamp onto the insulated conductor, replacing the grounding ring in existing technology. This effectively prevents unauthorized personnel from using the grounding ring for electrical connections, thus preventing damage to transmission lines. Furthermore, the inclusion of clamping teeth eliminates the need for exposed conductor sections. When the voltage testing clamp is installed, the teeth penetrate the conductor's insulation layer directly, achieving electrical connection. During voltage testing, the use of insulating materials for the voltage testing clamp, test rod, and fixing block ensures safer connection between the voltage testing head and the connection hole, effectively protecting operator safety. The rotatable connection between the connecting cylinder and the voltage testing clamp facilitates easy connection between the voltage testing cylinder and the test rod. Finally, the sealing ring provides excellent protection for the rotating shaft, effectively preventing corrosion caused by prolonged exposure to air.
[0007] Preferably, the card slot has upper mounting ring grooves on both sides corresponding to the second connecting hole, and lower mounting ring grooves corresponding to the upper mounting ring grooves at both ends of the first connecting hole. The upper mounting ring grooves and lower mounting ring grooves cooperate to form a mounting cavity, and the sealing ring is placed in the mounting cavity.
[0008] The sealing ring is set inside the mounting cavity. Since the sealing ring is located between the upper mounting groove and the lower mounting groove, it can fill the gap between the connecting block and the slot, thus achieving a better sealing effect.
[0009] Preferably, the sidewall of the voltage testing connection hole is provided with an axial groove along its axial direction, and the axial groove extends through the opening of the voltage testing connection hole; the sidewall of the voltage testing connection hole is provided with a circumferential groove along its circumferential direction, and the circumferential groove is connected to the end of the axial groove away from the opening of the voltage testing connection hole; the sidewall of the voltage testing head is provided with an outwardly protruding voltage testing block, and after the voltage testing block passes through the axial groove and rotates, the voltage testing block is engaged in the axial groove.
[0010] By incorporating axial and circumferential grooves, and in conjunction with the voltage testing block, the conical cover achieves a tighter contact with the voltage testing contact, while also facilitating the connection between the voltage testing head and the voltage testing connection hole. Preferably, an annular hole is provided on the end face of the connecting cylinder away from the voltage tester clamp, and an annular slider is provided in the annular hole along which it slides. A push rod is provided on the end face of the annular slider facing the annular hole, and a piston is provided at the end of the push rod. An air cylinder is provided at the bottom of the annular hole, and the piston is in contact with the inner wall of the air cylinder and slides along the air cylinder. A return spring is provided between the bottom of the air cylinder and the end face of the piston. An air outlet is provided on the side wall of the air cylinder. The sealing ring is an internally hollow air ring, and the air outlet is connected to the air ring through an air pipe.
[0011] When the voltage detector slides within the circumferential groove, it interacts with the inclined surface, pushing the annular slider into the annular hole. As the slider moves, the piston on the push rod slides along the inner wall of the air cylinder, forcing gas through the air pipe into the gas ring. This refills the gas ring with gas, causing it to expand and creating a tighter seal between the gas ring, connecting block, and slot. The gas ring then re-establishes its sealing function and simultaneously secures the voltage detector clamp and connecting cylinder, providing excellent wind protection. Because a one-way valve is installed at the air outlet, when the voltage detector and connecting cylinder separate, the annular slider returns to its original position via a return spring, while the gas within the gas ring maintains pressure, ensuring a good seal and wind protection.
[0012] Preferably, the first conductor includes clamping teeth disposed in the clamping jaw, and a conductive rod is connected to the clamping teeth; The second conductor is a conductive sleeve, which includes a conductive cylinder disposed inside the voltage testing connection hole.
[0013] Preferably, the voltage detector includes a fixing block and a voltage detector contact located at one end of the voltage detector rod; The voltage testing card is set on the side wall of the fixed block; The voltage testing contact is equipped with a connecting rod, which is slidably mounted inside the fixed block. A force-pressing spring abuts between the voltage testing contact and the fixed block.
[0014] The voltage tester is locked in the voltage test connection hole by the voltage tester clip. At the same time, because the top force spring is in a compressed state, the voltage tester is pushed by the top force spring, causing the voltage tester to abut against the conical cover, thereby ensuring a tight contact between the conical cover and the voltage tester.
[0015] As a preferred option, the voltage testing clamp includes: The first clamping block has a first clamping hole and a first clamping groove. The second clamping block has a second clamping hole and a second clamping groove, and the first clamping groove and the second clamping groove cooperate to form a clamping opening. Connecting bolts pass through the first clamping block hole and the second clamping block hole to connect the first clamping block and the second clamping block.
[0016] The voltage testing clamp is configured with a first clamp and a second clamp, making it easier for the first clamp and the second clamp to engage with the voltage testing grounding ring.
[0017] Preferably, the first conductor includes clamping teeth disposed in the clamping jaw, and a conductive rod is connected to the clamping teeth; the second conductor includes a conductive sleeve; the conductive rod and the conductive sleeve are connected by a conductive wire; the conductive sleeve includes a conductive tube disposed in the voltage testing connection hole, and a conical cap is provided at the end of the conductive tube away from the voltage testing connection hole. The voltage tester includes a fixing block at one end of the voltage tester rod and a voltage tester contact, which is a conical contact that mates with a conical cover.
[0018] The conical cover and the conical contact work together to make the contact between the conical cover and the conical contact tighter.
[0019] Preferably, a limiting clamp is provided at the end of the second clamping block away from the connecting cylinder, and the limiting clamp is in contact with the end face of the first clamping block away from the connecting cylinder.
[0020] The limiting clamp plate allows for a tighter fit between the first clamping block and the second clamping block.
[0021] As a preferred option, a vent valve is installed on the trachea.
[0022] The vent valve can release the gas in the gas ring, making it easier to rotate between the connecting cylinder and the voltage tester clamp.
[0023] Compared with the prior art, the beneficial effects of the present invention are: (1) Improve the safety of bridging voltage testing and effectively prevent the risk of electric shock during bridging voltage testing; the voltage testing clamp replaces the voltage testing grounding ring in the existing technology, and there is no need to set up exposed insulation parts, which can effectively prevent illegal personnel from bridging electricity and prevent damage to the transmission line. (2) When testing for grounding, it is more convenient to connect the test rod and the test clamp, which effectively ensures the safety of the operator; (3) An air ring is provided. The air ring can rotate the shaft and play a good sealing role, and at the same time play a good windproof role, which effectively improves the service life of the present invention.

[0025] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Example 1: Refer to Figures 1 to 6 As shown, a convenient voltage detector assembly mainly consists of three parts: a voltage detector clamp 1, a conductive component 3, and a voltage detector rod 4. The voltage testing clamp 1 has a clamping opening 11 at one end and a connecting cylinder 2 at the other end. The connecting cylinder 2 has a voltage testing connection hole 21 inside. The voltage testing clamp 1 is made of insulating material. The voltage testing clamp 1 includes a first clamping block 13 and a second clamping block 14. The first clamping block 13 has a first clamping block hole 131 and a first clamping groove 132. The second clamping block 14 has a second clamping block hole 141 and a second clamping groove 142. The first clamping groove 132 and the second clamping groove 142 cooperate to form the clamping opening 11. The connecting bolt 15 passes through the first clamping block hole 131 and the second clamping block hole 141 and cooperates with the nut to connect the first clamping block 13 and the second clamping block 14. The conductive component 3 is fixedly installed inside the voltage testing clamp 1, including a first conductor fixedly installed in the clamp 11 and a second conductor installed in the connection hole 21. The first conductor and the second conductor are connected by a conductive wire 33. The first conductor is a clamping tooth 31 installed in the clamp 11, and a conductive rod 311 is connected to the clamping tooth 31. The second conductor is a conductive sleeve 32, which includes a conductive cylinder 321 installed in the voltage testing connection hole. A conical cap 322 is provided at the end of the conductive cylinder 321 away from the voltage testing connection hole 21, and the conductive wire 323 is connected between the end of the conical cap 322 and the conductive rod 311. The voltage tester 4 has a hollow through hole 41 along its length. One end of the voltage tester 4 is provided with a voltage test head 5 that mates with the connection hole 21. The voltage test head 5 includes a fixing block 51 fixedly disposed at one end of the voltage tester 4 and a voltage test contact 52. The voltage test contact 52 is a conical contact that mates with the conical cover 322. A fixing connection block 512 that connects to the voltage tester 4 is provided on the side of the fixing block 51 away from the voltage test contact 52. A fixing connection groove 411 is provided at the opening position of the through hole 41. A fixing connection protrusion that mates with the fixing connection groove 411 is provided on the fixing connection block 512. Both the voltage tester 4 and the fixing block 51 are made of insulating material.
[0026] A connecting rod 521 is provided on the voltage testing contact 52, and a voltage testing component is provided inside the voltage testing rod 4. The connecting rod 521 is inserted into the fixing block 51. The voltage testing component is existing technology and can detect whether it is energized. The voltage testing component is connected to the connecting rod 521, and a grounding wire 42 is connected to the end of the voltage testing component away from the connecting rod 521.
[0027] The end of the second clamping block 14 away from the connecting cylinder 2 is provided with a limiting clamping plate 143, which is in contact with the end face of the first clamping block 13 away from the connecting cylinder 2.
[0028] An insulating cylinder 323 is installed inside the conductive cylinder 321.
[0029] Furthermore, in this embodiment, to facilitate the connection between the voltage tester 4 and the voltage tester connection hole 21, the connecting cylinder 2 is rotatably connected to the voltage tester clamp 1. Specifically, a connecting block 12 is provided at one end of the first clamping block 13 near the connecting cylinder 2. The connecting block 12 has a first connecting hole 121, and the connecting cylinder 2 has a groove 22 that mates with the connecting block 12. Second connecting holes 221 are provided on both sides of the groove 22, and the rotating shaft 222 passes through the first connecting hole 121 and the second connecting hole 221. This allows the connecting block 12 to rotate around the rotating shaft 222. A sealing ring 224 is provided between the opposing surfaces of the slot 22 and the connecting block 12, and the sealing ring 224 is sleeved on the outer periphery of the rotating shaft 222. Specifically, the slot 22 has upper mounting ring grooves 223 on both sides corresponding to the second connecting hole 211, and lower mounting ring grooves 122 at both ends of the first connecting hole 121 corresponding to the upper mounting ring grooves 223. The upper mounting ring grooves 223 and the lower mounting ring grooves 122 cooperate to form a mounting cavity, and the sealing ring 224 is disposed in the mounting cavity.
[0030] To facilitate the connection between the voltage tester 4 and the voltage test connection hole 21, the connecting cylinder 2 and the voltage tester clamp 1 are connected by a rotating shaft 222; this allows the connecting cylinder 2 to be adjusted to any angle with the voltage tester 1, facilitating the connection between the voltage tester 4 and the voltage test connection hole 21.
[0031] The working principle of this embodiment is as follows: In use, the voltage testing clamp 1 is first fixedly mounted on the insulated wire. Specifically, the first clamping groove 132 on the first clamping block 13 and the second clamping groove 142 on the second clamping block 14 clamp the insulated wire. Then, the first clamping block 13 and the second clamping block 14 are fastened together by the connecting bolt 15 and the nut, so that the clamping teeth 31 in the clamping mouth 11 contact the insulated wire. When voltage testing and grounding are required, the voltage testing head 5 at the end of the voltage testing rod 4 is inserted into the voltage testing connection hole 21, so that the voltage testing contact 52 contacts the conical cap 2 at the end of the conductive cylinder 321. Then, voltage testing is performed through the voltage testing component in the voltage testing rod 4. After voltage testing is completed, grounding is performed through the grounding wire 42. In specific connection, an external thread can be provided in the circumferential direction of the fixing block 51, and an internal thread is provided in the voltage testing connection hole 21 to cooperate with the external thread of the fixing block 51, so that the voltage testing head 5 and the voltage testing connection hole 21 can be easily fixedly connected.
[0032] This invention pre-fixes the voltage testing clamp 1 onto the conductor, replacing the existing voltage testing grounding ring. This effectively prevents unauthorized personnel from using the voltage testing grounding ring for electrical connections, thus preventing damage to the transmission line caused by such connections. Furthermore, the inclusion of clamp teeth 31 eliminates the need for exposed portions on the conductor. When the voltage testing clamp 1 is installed on the conductor, the clamp teeth 31 penetrate the conductor's insulation layer, achieving electrical connection between the clamp teeth 31 and the conductor. When voltage testing is required, the use of insulating materials for the voltage testing clamp 1, voltage testing rod 4, and fixing block 51 ensures safer connection of the voltage testing head 5 and the voltage testing connection hole 21, effectively guaranteeing the personal safety of the operator.
[0033] Meanwhile, in this invention, two sealing rings 224 are provided, which are respectively provided on the two end faces of the connecting block 12 and the slot 22 in contact. Since there is a gap between the slot 22 and the connecting block 12, the sealing rings 224 wrap the part of the rotating shaft 22 inside the connecting block 12, which mainly plays a sealing role and prevents the rotating shaft 22 from being exposed to the air for a long time and being corroded.
[0034] Example 2: Refer to Figures 1 to 6 As shown, this embodiment is similar in structure to embodiment 1. The difference is that this embodiment is designed to make the contact between the conical cover 322 and the voltage testing contact 52 tighter, and to make the connection between the voltage testing head 5 and the voltage testing connection hole 21 more convenient.
[0035] Specifically, the sidewall of the voltage testing connection hole 21 is provided with an axial groove 211 along its axial direction, and the axial groove 211 extends through the opening of the voltage testing connection hole 21; the sidewall of the voltage testing connection hole 21 is provided with a circumferential groove 212 along its circumferential direction, and the circumferential groove 212 is connected to the end of the axial groove 211 away from the opening of the voltage testing connection hole 21; the sidewall of the voltage testing head 5 is provided with an outwardly protruding voltage testing block 511, and after the voltage testing block 511 passes through the axial groove 211 and rotates, the voltage testing block 511 is engaged in the circumferential groove 212.
[0036] The voltage tester 5 includes a fixing block 51 and a voltage tester contact 52 disposed at one end of the voltage tester rod 4; a voltage tester clip 511 is disposed on the side wall of the fixing block 51; a connecting rod 521 is disposed on the voltage tester contact 52, the connecting rod 521 is slidably disposed in the fixing block 51, and a force spring 53 abuts between the voltage tester contact 52 and the fixing block 51.
[0037] To further and more effectively prevent electric shock, an insulating sleeve 54 is provided at the outer end of the top spring 53.
[0038] In this embodiment, the specific structure is as follows: a connecting post 23 is provided at one end of the connecting cylinder 2; a first mounting hole is provided on the connecting post 23 along its axial direction; a conductive cylinder 321 is provided in the first mounting hole; a conical cover 322 is provided at the bottom end of the first mounting hole; a connecting sleeve 24 is threadedly connected to the outer side of the connecting post 23; a connecting ring 25 is threadedly connected to the inner side of the connecting sleeve 24; the hollow part of the connecting ring 25 and the first mounting hole form an electrical testing connecting hole 21; an axial groove 211 is provided on the connecting ring 25; there is a certain distance between the connecting ring 25 and the connecting post 23; the distance between the connecting ring 25 and the connecting post 23 forms a circumferential groove.
[0039] The working principle of this implementation is as follows: In use, first insert the voltage testing contact 52 into the voltage testing connection hole 21, and simultaneously align the voltage testing block 511 with the axial groove. When the voltage testing contact 52 contacts the conical cover 322, the voltage testing block 511 is located within the axial groove. Then, continue pushing the voltage testing rod 4, causing the fixing block 51 to overcome the force spring 53 and move towards the voltage testing connection hole 21. At this time, the connecting rod 521 slides within the fixing block 51, and the force spring 53 is compressed. When the voltage testing block 511 moves to the circumferential groove 212, the voltage testing... The test rod 4 rotates 180°, causing the voltage testing block 511 to disengage from the axial groove 211. The voltage testing block 511 slides within the circumferential groove 212, thus being locked in place by the circumferential groove 21. This locks the test rod 4 into the voltage testing connection hole 21 via the voltage testing block 511. Simultaneously, the force spring 53 is compressed, causing the voltage testing contact 52 to be pushed by the force spring 53, bringing it into contact with the conical cover 322. This ensures a tight contact between the conical cover 322 and the voltage testing contact 52. Similarly, when it is necessary to remove the voltage testing head 5 from the voltage testing connection hole 21, simply rotate the voltage testing head 5 in the opposite direction, causing the voltage testing block 511 to rotate within the circumferential groove 212 and then slide out of the axial groove 211, allowing the voltage testing head 5 to be removed from the voltage testing connection hole 21.
[0040] Example 3: Reference Figures 1 to 8As shown, this embodiment is similar in structure to Embodiment 2, except that an annular hole 26 is provided on the end face of the connecting cylinder 2 away from the voltage testing clamp 1, and an annular slider 261 is provided inside the annular hole 26, sliding along it. An inclined surface 264 is provided on the end face of the annular slider 261 away from the annular hole 26, and a push rod 262 is provided on the end face of the annular slider 261 facing the annular hole 26. A piston 263 is provided at the end of the push rod 262. An air cylinder 6 is provided at the bottom of the annular hole 26, and the piston 263 is in contact with the inner wall of the air cylinder 6 and slides along it. The cylinder 6 slides, and a return spring 61 is provided between the bottom of the cylinder 6 and the end face of the piston 263. The side wall of the cylinder 6 is provided with an air outlet 62 and an air inlet. A one-way valve that can only allow air to enter is provided at the air inlet, and a one-way valve that can only allow air to exit is provided at the air outlet 62. The sealing ring 224 is an elastic and hollow air ring 225. The air outlet 62 is connected to the air ring 225 through the air pipe 63. A vent valve 64 (which is the prior art) is provided on the air pipe 63. By pressing the vent button on the vent valve 64, manual venting can be performed.
[0041] Setting the sealing ring 224 as an air ring 225 has another advantage besides maintaining the sealing performance. Because the gas inside the air ring 225 has a certain pressure, the air ring 225 abuts against the connecting block 12 and the slot 22, which can fix the voltage testing clamp 1 and the connecting cylinder 2. Since the voltage testing clamp 1 is usually set at a high altitude, the air ring 225 plays a good role in wind protection, preventing the continuous friction between the connecting cylinder 2 and the voltage testing clamp 1 caused by wind force from causing wear on the rotating shaft 22 or damage to the connecting cylinder 2 and the voltage testing clamp 1.
[0042] However, it was found during use that, since the gas ring 225 is located between the slot 22 and the connecting block 12, the gas inside the gas ring 225 needs to have a certain pressure in order to achieve a good sealing effect. The higher the pressure inside the gas ring 225, the better. However, due to the excessive pressure inside the gas ring 225, it is very difficult to rotate the connecting cylinder 2 when installing the voltage tester 4. Therefore, the above-mentioned technical solution is set in embodiment 3.
[0043] The working principle of this embodiment is as follows: Before use, press the vent button to release the gas in the gas ring 225 through the vent valve 64, thereby reducing the pressure in the gas ring 225 and facilitating the rotation of the connecting cylinder 2. When the voltage tester 4 and the connecting cylinder 2 are connected, the connection steps are the same as in embodiment 2. The difference is that when the voltage tester block 511 slides in the circumferential groove 212, the voltage tester block 511 will interact with the inclined surface 264, and the voltage tester block 511 will push the annular slider 261 toward the annular hole. When the annular slider 261 moves within the cylinder 296, the piston 263 on the push rod 262 slides along the inner wall of the air cylinder 6, forcing the gas in the air cylinder 6 through the air pipe 63 into the air ring 225. This causes the air ring 225 to refill with gas, which expands the air ring 225, making the air ring 225, connecting block 2, and slot 22 fit more tightly, thus restoring the sealing function of the air ring 225. Simultaneously, it also secures the voltage tester clamp 1 and connecting cylinder 2, providing good wind protection. Because a one-way valve is installed at the air outlet 62, allowing gas to exit only from the outlet 62, the gas in the air ring 225 will not leak from the outlet 62. Therefore, when the voltage tester 4 and connecting cylinder 2 separate, the annular slider 261 resets under the action of the return spring 61, while the gas in the air ring 225 maintains pressure, providing good sealing and wind protection.
[0044] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Other variations and modifications may be made without departing from the technical solutions described in the claims.
