Description

Technical Field

[0001] This utility model relates to the field of grounding wire processing technology, and in particular to a grounding wire processing device for power switchgear. Background Technology

[0002] In the installation and maintenance of power switchgear, reliable grounding connection is crucial for ensuring equipment leakage protection and the safe operation of the power grid. Due to differences in the installation location and cabinet specifications of switchgear in various scenarios, to avoid messy wiring due to excessively long grounding wires or grounding failure due to excessively short wires, it is necessary to cut grounding wires to an appropriate length on-site according to the actual working conditions. Simultaneously, to achieve effective connection between the grounding wire and the grounding system, a grounding terminal must be crimped onto the end of the cut grounding wire. These operations typically involve connecting rings for connecting to the grounding system and connecting sleeves for wrapping the grounding wire core; therefore, "on-site processing of grounding wires and grounding terminals" becomes a necessary procedure.

[0003] Currently, the industry mainly uses manual crimping with pliers to connect grounding terminals and grounding wires. This method has significant drawbacks: First, the crimping force depends entirely on the operator's experience. Excessive pressure can cause the grounding wire core to break or the insulation layer to be damaged, leaving a short circuit hazard. Insufficient pressure results in the terminal and grounding wire not fitting tightly, easily leading to excessive contact resistance or even vibration-induced detachment, seriously affecting the grounding protection effect. Second, a large number of grounding wires need to be processed during on-site construction, and manual crimping is labor-intensive and inefficient, especially when working at heights or in confined spaces, where operational convenience and safety are even more difficult to guarantee.

[0004] To address the aforementioned technical problems, Chinese Patent Application No. 200810067192.2 discloses a power cord plug and its manufacturing method. The core of this method involves prefabricating components such as insert / copper rod terminals and plug housings using an injection molding machine, connecting the terminals to the power cord via welding or riveting, and then bonding the housing using an ultrasonic pressing machine to complete the mass production of the power cord plug in the factory. However, this solution still has the following shortcomings in practical use: First, the solution relies on large, fixed equipment such as injection molding machines and ultrasonic pressing machines, making them difficult to carry and adapt to temporary processing on construction sites; second, the connection method is welding or riveting, lacking a pressing force detection and control mechanism, failing to solve the core problem of "difficulty in controlling the force" when pressing the grounding terminal; third, the solution lacks a positioning structure for the terminals and a portable operation design, making it prone to terminal displacement during on-site use and unsuitable for construction scenarios without a fixed power supply.

[0005] Therefore, existing technologies cannot provide an effective solution, and the industry lacks a power switchgear grounding wire processing device that can achieve portable on-site operation, precise control of pressing force, and reliable terminal positioning. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies, such as difficulties in carrying and operation, low precision in pressure control, and poor positioning reliability, and to provide a grounding wire processing device for power switchgear.

[0007] This utility model is achieved through the following technical solution: a grounding wire processing device for power switchgear, comprising a handheld gun and a grounding terminal. The working end of the handheld gun is provided with a pressing mechanism that cooperates with the grounding terminal. The grounding terminal is located at the tail end of the grounding wire. Through the pressing mechanism, the grounding terminal can be pressed together with the tail end of the grounding wire. The pressing mechanism includes an upper support rod, a lower support rod, a telescopic cylinder, a lower pressure plate, a pressure sensor, and a pressure-bearing frame. The upper support rod is located at the working end of the handheld gun, and the upper end of the lower support rod is connected to the upper support rod. The telescopic cylinder is located at the end of the upper support rod away from the handheld gun, with its extended end facing the lower end of the lower support rod. The lower pressure plate is located below the extended end of the telescopic cylinder, and the pressure sensor is located between the extended end of the telescopic cylinder and the lower pressure plate. The pressure-bearing frame is located below the lower pressure plate, at the lower end of the lower support rod corresponding to the position of the lower pressure plate, and the lower pressure plate can enter into the pressure-bearing frame. The handheld gun is equipped with a control panel, which contains an intelligent controller. The control panel is electrically connected to the telescopic cylinder and the pressure sensor.

[0008] Compared to the traditional manual clamping method, this device achieves portability through a "removable battery block," solving the problem of operation without a fixed power source on site. The combination of "pressure sensor + intelligent controller" enables precise control of the clamping force, effectively avoiding the problems of "excessive pressure damaging the grounding wire" or "insufficient pressure causing unstable connection" that occur during manual operation. At the same time, the "protective frame" can prevent the risk of misoperation. The overall structure meets the core requirements of on-site processing of grounding wires for power switchgear, and compared with existing technologies, it significantly improves the adaptability to different scenarios and the flexibility of operation.

[0009] A further improvement of this utility model is that the grounding terminal is made of conductive metal, the grounding terminal includes a connecting ring plate and a connecting sleeve, the ring plate and the connecting sleeve are integrally connected, and the tail end of the grounding wire is inserted into the interior of the connecting sleeve.

[0010] A further improvement of this utility model is that the pressing mechanism also includes a support block, which is disposed on the horizontal part of the lower support rod close to the pressure frame, and the connecting ring is placed on top of the support block.

[0011] A further improvement of this utility model is that the pressing mechanism also includes a magnetic ring, which is disposed on the upper part of the support block and can be magnetically connected to the connecting ring plate.

[0012] A further improvement of this utility model is that the pressing mechanism further includes a constraint circular plate, which is located inside the magnetic ring, and the connecting circular plate can be sleeved on the outside of the constraint circular plate.

[0013] A further improvement of this utility model is that a fixed sleeve is provided at the end of the upper support rod away from the handheld gun, and the telescopic cylinder is disposed inside the fixed sleeve.

[0014] A further improvement of this utility model is that the lower support rod has an L-shaped structure, and the upper end of the vertical part of the lower support rod is connected to the upper support rod. The pressure-bearing frame is set at the position of the lower pressure plate corresponding to the horizontal part of the lower support rod, and the extended end of the telescopic cylinder faces the horizontal part of the lower support rod.

[0015] A further improvement of this utility model is that the pressure-bearing frame has a U-shaped structure, and the open end of the pressure-bearing frame corresponds to the lower pressure plate.

[0016] A further improvement of this utility model is that the upper support rod has a built-in connecting wire, through which the control panel is electrically connected to the telescopic cylinder and the pressure sensor.

[0017] A further improvement of this utility model is that the bottom of the lower pressure plate is an arc-shaped groove.

[0018] As can be seen from the above technical solutions, the beneficial effects of this utility model are: 1. This device has significant advantages in terms of scene adaptability and portability, effectively making up for the shortcomings of existing technologies. Existing technologies rely on large, fixed equipment such as injection molding machines and ultrasonic pressing machines, which cannot be separated from the factory environment; while this device, based on a handheld gun with a detachable battery, does not require an external power source and can flexibly adapt to mobile operations at the installation and maintenance site of power switchgear. Whether working at heights, in confined spaces, or performing immediate processing after cutting grounding wires on site, it can respond efficiently and completely solve the defect of "no suitable equipment for on-site processing".

[0019] 2. This device significantly improves the reliability and processing quality of the connection between the grounding terminal and the grounding wire through precise control and structural optimization. Traditional manual crimping with pliers relies on experience, which can easily lead to excessive pressure damaging the wire or insufficient pressure causing a loose connection; comparison document 1 relies solely on welding / riveting connections without pressure force detection and control. This device uses a "pressure sensor + intelligent controller" to control the pressure in real time, ensuring that the force is within the standard range; the grounding terminal is made of a highly conductive metal, and the connecting sleeve wraps around the wire core and is then crimped to fit snugly, ensuring conductivity, reducing grounding resistance, and strengthening the connection to prevent the terminal from falling off.

[0020] 3. This device enhances operational convenience, safety, and durability through meticulous design. The magnetic ring and constraint plate automatically achieve magnetic positioning and radial limiting of the grounding terminal, eliminating the need for manual intervention and reducing reliance on experience. The support block prevents deformation of the connecting ring plate, the built-in connecting wire reduces wear and tear, and the trigger protection frame prevents accidental operation. These designs reduce labor intensity, extend device life, and create a system more adaptable to field operations, superior to existing technologies without positioning assistance.

Detailed Implementation

[0028] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0029] Now refer to Figures 1-5The following is a description of a specific embodiment: The power switchgear grounding wire processing device of this utility model includes a handheld gun 2 and a grounding terminal 3. Referring to existing industrial-grade handheld equipment, the handheld gun 2 includes a trigger and a grip. A detachable battery block is installed inside the grip, and a protective frame strip is installed on the outside of the trigger of the handheld gun 2. The working end of the handheld gun 2 is provided with a pressing mechanism that cooperates with the grounding terminal 3. The grounding terminal 3 is located at the tail end of the grounding wire 1. Through the pressing mechanism, the grounding terminal 3 can be pressed together with the tail end of the grounding wire 1. The pressing mechanism includes an upper support rod 4, a lower support rod 5, a telescopic cylinder 6, a lower pressure plate 7, a pressure sensor 8, and a pressure-bearing frame 9. The upper support rod 4 is located at the working end of the handheld gun 2, and the lower support rod... 5 is an L-shaped structure, and the upper end of the vertical part of the lower support rod 5 is connected to the upper support rod 4; the telescopic cylinder 6 is located at the end of the upper support rod 4 away from the handheld gun 2, and the extended end of the telescopic cylinder 6 faces the horizontal part of the lower support rod 5; the lower pressure plate 7 is located below the extended end of the telescopic cylinder 6, and the pressure sensor 8 is located between the extended end of the telescopic cylinder 6 and the lower pressure plate 7; the pressure-bearing frame 9 is a U-shaped structure, located below the lower pressure plate 7, and the pressure-bearing frame 9 is located at the position of the horizontal part of the lower support rod 5 corresponding to the lower pressure plate 7, and the lower pressure plate 7 can enter into the pressure-bearing frame 9; the handheld gun 2 is equipped with a control panel 10, and the control panel 10 is equipped with an intelligent controller, and the control panel 10 is electrically connected to the telescopic cylinder 6 and the pressure sensor 8.

[0030] In use, first insert the tail end of the grounding wire 1 to be processed into the grounding terminal 3, then hold the handheld gun 2 with a handle. The removable battery block inside the handle powers the entire device, eliminating the need for an external fixed power source, making it suitable for mobile operations during the installation and maintenance of power switchgear. The protective frame strip on the outside of the trigger effectively prevents accidental triggering and misoperation. After starting the device, set the target pressing force through the control panel 10 on the handheld gun 2. The built-in intelligent controller sends a start signal to the telescopic cylinder 6. The extended end of the telescopic cylinder 6 extends horizontally towards the lower support rod 5, driving the lower pressure plate 7 to move down synchronously until the lower pressure plate 7 enters the pressure frame 9 of the lower U-shaped structure. At this time, the lower pressure plate 7 cooperates with the pressure frame 9 to apply pressure to the grounding terminal 3 and the tail end of the grounding wire 1 placed between them. During the process, the pressure sensor 8 between the extended end of the telescopic cylinder 6 and the lower pressure plate 7 detects the pressing force in real time and transmits the pressure signal to the intelligent controller. When the detected pressure reaches the set value, the intelligent controller immediately controls the telescopic cylinder 6 to stop extending, completing the pressing operation.

[0031] Compared to the traditional manual clamping method, this device achieves portability through a "removable battery block," solving the problem of operation without a fixed power source on site. The combination of "pressure sensor + intelligent controller" enables precise control of the clamping force, effectively avoiding the problems of "excessive pressure damaging the grounding wire" or "insufficient pressure causing unstable connection" that occur during manual operation. At the same time, the "protective frame" can prevent the risk of misoperation. The overall structure meets the core requirements of on-site processing of grounding wires for power switchgear, and compared with existing technologies, it significantly improves the adaptability to different scenarios and the flexibility of operation.

[0032] Specifically, refer to Figure 2 The grounding terminal 3 is made of conductive metal. The grounding terminal 3 includes a connecting ring plate 301 and a connecting sleeve 302. The ring plate 301 and the connecting sleeve 302 are integrally connected. The tail end of the grounding wire 1 is inserted into the interior of the connecting sleeve 302.

[0033] The grounding terminal 3 is made of a metal with good conductivity. Its integrally connected connecting ring 301 and connecting sleeve 302 form a structure suitable for grounding operation: Before processing, the tail end of the grounding wire 1 is inserted into the connecting sleeve 302 so that the connecting sleeve 302 completely wraps the wire core of the grounding wire 1; during the pressing process, the lower pressure plate 7 and the pressure frame 9 apply pressure to the connecting sleeve 302, forcing the connecting sleeve 302 to undergo plastic deformation and tightly fit the wire core of the grounding wire 1, while the connecting ring 301 maintains structural integrity. After pressing is completed, it is used to connect with the grounding system such as the grounding busbar of the switch cabinet.

[0034] The use of a "metal material with good conductivity" ensures that the grounding terminal 3 has reliable conductivity, avoiding excessive grounding resistance due to insufficient material conductivity and ensuring the leakage protection effect of the power system. The structural design of "connecting sleeve 302 wrapping the wire core + pressing and deformation" greatly improves the connection between the grounding terminal 3 and the grounding wire 1. Compared with simple terminals without connecting sleeves, it effectively reduces the risk of terminal detachment during long-term use. The "connecting ring 301" simplifies the subsequent docking process with the grounding system, eliminating the need for additional processing of the connection structure and improving overall work efficiency.

[0035] Specifically, refer to Figure 5 The pressing mechanism also includes a support block 11, which is located on the horizontal part of the lower support rod 5 close to the pressure frame 9, and the connecting ring plate 301 is placed on top of the support block 11.

[0036] Before pressing, the connecting ring 301 of the grounding terminal 3 is placed on the top of the support block 11. The support block 11 is fixed to the horizontal part of the lower support rod 5 and close to the pressure frame 9, forming a support structure for the connecting ring 301. During pressing, the lower pressure plate 7 applies pressure to the connecting sleeve 302. Due to the support of the support block 11, the connecting ring 301 only bears the stable support force in the vertical direction, avoiding bending or displacement due to the deformation of the connecting sleeve 302.

[0037] The device effectively prevents the connecting ring plate 301 from deforming under stress during the pressing process by setting the support block 11, ensuring its structural integrity when connected to the grounding system. If the ring plate is deformed, it may not fit tightly with the grounding bar, increasing the grounding resistance. At the same time, the support block 11 supports and positions the connecting ring plate 301, indirectly ensuring the alignment accuracy of the connecting sleeve 302 with the lower pressure plate 7 and the pressure frame 9, further improving the stability of the pressing quality.

[0038] Specifically, refer to Figure 2 and Figure 5 The pressing mechanism also includes a magnetic ring 12, which is disposed on the upper part of the support block 11 and can be magnetically connected to the connecting ring plate 301.

[0039] When the grounding terminal 3 is placed before pressing, the magnetic ring 12 on the upper part of the support block 11 forms a magnetic connection with the metal material of the connecting ring plate 301 through its own magnetism, which firmly fixes the connecting ring plate 301 to the top of the support block 11, so that the grounding terminal 3 can be kept in a stable position without manual support; during the pressing process, the magnetic force can resist the slight displacement tendency caused by the vertical extrusion force applied by the lower pressure plate 7, ensuring that the grounding terminal 3 is always in the preset pressing position.

[0040] This device frees up the operator's hands by using magnetic fixation, eliminating the need to manually support the grounding terminal. This significantly improves operational convenience and safety, especially when working at heights or in confined spaces. Furthermore, compared to mechanical snap-fit ​​positioning, magnetic positioning eliminates the need for frequent disassembly and assembly, and does not cause scratches or damage to the connecting ring 301, thus ensuring both positioning reliability and terminal integrity.

[0041] Specifically, refer to Figure 2 , Figure 4 and Figure 5 The pressing mechanism also includes a constraint circular plate 13, which is located inside the magnetic ring 12, and the connecting circular ring 301 can be sleeved on the outside of the constraint circular plate 13.

[0042] When placing the grounding terminal 3, the connecting ring 301 is sleeved on the outside of the constraint plate 13 inside the magnetic ring 12. The constraint plate 13 limits the radial position of the connecting ring 301 through radial limiting, ensuring that the center of the connecting ring 301 is aligned with the center of the constraint plate 13. This allows the connecting sleeve 302 of the grounding terminal 3 to be precisely aligned with the pressing center of the lower pressure plate 7 and the pressure frame 9, preventing radial offset between the connecting sleeve 302 and the tail end of the grounding wire 1.

[0043] The device constrains the radial limit function of the circular plate 13, which solves the problem of "radial offset of the circular plate" that may exist when relying solely on the magnetic attraction of the magnetic ring 12. This greatly improves the consistency of the position of the grounding terminal 3 during each pressing, and avoids "partial pressing failure" caused by the misalignment of the connecting sleeve 302 and the grounding wire 1. At the same time, the standardized positioning method can reduce the reliance on the operator's experience, and even novices can quickly complete accurate positioning, improving work efficiency and quality consistency.

[0044] In one embodiment, reference Figure 1 The upper support rod 4 is provided with a fixed sleeve 14 at the end away from the handheld gun 2, and the telescopic cylinder 6 is located inside the fixed sleeve 14.

[0045] The telescopic cylinder 6 is installed inside the fixed sleeve 14 at the end of the upper support rod 4 away from the handheld gun 2. The fixed sleeve 14 limits the axial and radial displacement of the telescopic cylinder 6 through the tight fit between the inner wall and the outer wall of the telescopic cylinder 6. When the telescopic cylinder 6 is working, it extends or retracts. The fixed sleeve 14 can resist the shaking or offset tendency of the telescopic cylinder 6 caused by the force, ensuring that the extended end of the telescopic cylinder 6 always moves in the preset vertical direction, thereby ensuring that the lower pressure plate 7 is accurately aligned with the pressing area of ​​the pressure frame 9.

[0046] This device significantly improves the installation stability of the telescopic cylinder 6 through the setting of the fixing sleeve 14, avoiding the problems of "lower pressure plate offset and pressure force deviation" caused by the shaking of the telescopic cylinder 6. If the pressure force is biased, it may cause excessive deformation on one side of the connecting sleeve 302, while the other side is not fully pressed. At the same time, the fixing sleeve 14 can provide physical protection for the telescopic cylinder 6, reduce the corrosion of the telescopic cylinder 6 by dust and debris during on-site operations, and extend the service life of the telescopic cylinder 6.

[0047] In one embodiment, reference Figure 1 The upper support rod 4 has a built-in connecting wire, through which the control panel 10 is electrically connected to the telescopic cylinder 6 and the pressure sensor 8.

[0048] The upper support rod 4 has a built-in connecting wire. One end of the connecting wire is connected to the intelligent controller and power interface of the control panel 10, and the other end is connected to the power interface of the telescopic cylinder 6 and the signal interface of the pressure sensor 8, respectively. During operation, the connecting wire can stably transmit the power signal from the intelligent controller to the telescopic cylinder 6 to control the telescopic movement, and the pressure detection signal from the pressure sensor 8 to the intelligent controller. The connecting wire is hidden inside the upper support rod 4 and does not come into direct contact with the outside.

[0049] This device avoids the problems of traditional external wiring being susceptible to pulling, wear, and oil contamination by its built-in connection design, significantly reducing the risk of line failure, such as control failure or signal transmission interruption due to line breakage, thus improving the overall reliability of the device. At the same time, the concealed layout makes the device look simpler and reduces the interference of wiring on operation, such as preventing the wiring from snagging on internal components of the switch cabinet, further adapting to complex on-site working environments.

[0050] In one embodiment, reference Figure 1 The bottom of the lower pressure plate 7 is an arc-shaped groove.

[0051] During the pressing operation, the arc-shaped groove at the bottom of the lower pressure plate 7 and the outer surface of the connecting sleeve 302 of the grounding terminal 3 are mostly cylindrical or frustum-shaped, forming a close contact. The curved surface structure of the arc-shaped groove can increase the contact area between the lower pressure plate 7 and the connecting sleeve 302. Compared with the flat lower pressure plate, the arc-shaped groove can make the pressing force more evenly distributed in the circumferential direction of the connecting sleeve 302, avoiding local pressure concentration.

[0052] The uniformly distributed pressing force can prevent the connecting sleeve 302 from "cracking or metal fatigue" due to excessive local pressure, or "not fitting tightly" due to insufficient local pressure, ensuring that the connecting sleeve 302 deforms uniformly as a whole and fits tightly with the core of the grounding wire 1; at the same time, the increased contact area can reduce the pressure mark damage to the connecting sleeve 302 by the lower pressure plate, ensuring the structural strength and conductivity of the grounding terminal 3.

[0053] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
