Abstract
Description
Technical Field
[0001] This invention relates to the field of cable connector technology, and in particular to a cable connector for a power distribution cabinet. Background Technology
[0002] A distribution cabinet is a standardized cabinet in a power system used to centrally install electrical components such as distribution switches, protection devices, monitoring instruments, and connectors. Its core function is to receive, distribute, control, and protect input electrical energy, ensuring the safe and reliable transmission of power to various power terminals. It is widely used in buildings, factories, infrastructure, and other applications, and is a key node in the power distribution network. To ensure the absolute safety and stable operation of cable electrical connections, cable connectors are used to fix the cables to the distribution cabinet. This prevents the joints from loosening or falling off due to cabinet vibration, cable weight, or accidental pulling, and avoids problems such as overheating, sparks, or even fires caused by poor cable contact. This also meets the mandatory requirements of electrical installation specifications for cable mechanical stress relief and reliable grounding.
[0003] Currently, the cable connectors used in power distribution cabinets still have the following problems: Most cable connectors in existing power distribution cabinets use bolt crimping, elastic clamping, or fixing clamps. Although these methods can provide initial clamping force for the cables, during the operation of the power distribution cabinet, there will be continuous vibration, thermal expansion and contraction of the cables themselves, or accidental external pulling. At this time, the clamping force on the cables cannot adapt to changes, resulting in safety hazards such as increased contact resistance, overheating, or even power outages due to loose cables. At the same time, although some cable connectors have anti-loosening designs, such as adding locking nuts, manual active force or intervention is still required. There is a lack of a structure that automatically converts unfavorable external pulling force into clamping force, making it difficult for the cable connectors to provide safety protection at the cable connection points when the power distribution cabinet is in use. Summary of the Invention
[0004] In view of the problem of constant clamping force in the cable connectors of power distribution cabinets in the above or existing technologies, this invention is proposed.
[0005] To solve the above-mentioned technical problems, the present invention provides a power distribution cabinet cable connector, which is achieved by the following specific technical means:
[0006] A cable connector for a power distribution cabinet includes a cabinet and a fixed housing that is fixedly installed inside it for connecting cables. A connecting cylinder is fixedly installed inside the fixed housing, and several arc-shaped frames that move up and down are arranged in a circumferential array inside the connecting cylinder.
[0007] Several arc-shaped pressure blocks are arranged in a linear array inside the arc-shaped frame. The arc-shaped pressure blocks are hinged to the connecting cylinder by a set pin. An inclined secondary arc-shaped pressure block is fixedly installed on the upper end of the arc-shaped pressure block, and the size of the secondary arc-shaped pressure block is larger than that of the arc-shaped pressure block. A connecting rod is ball-hinged at the lower end of the arc-shaped frame. Several connecting rods are provided with a wire fixing mechanism at their lower ends for fixing to the outer wall of the cable.
[0008] When the cable passes through the connecting cylinder, the surrounding arc-shaped pressure blocks press and fix the outer wall of the cable. When the cable is pulled, the cable fixing mechanism tilts and pulls the corresponding arc-shaped frame down through the connecting rod. The arc-shaped pressure block rotates and switches to a secondary arc-shaped pressure block that contacts the outer wall of the cable. This is used to increase the clamping force on the cable by increasing the degree of compression on the force-bearing side of the cable through unfavorable external force.
[0009] Preferably, the connecting cylinder consists of an upper ring cover at the upper end and a mounting cylinder at the lower end. The pin on the arc-shaped pressure block passes through the outer ring wall of the mounting cylinder, and the outer walls of both the arc-shaped pressure block and the secondary arc-shaped pressure block are covered with a rubber layer.
[0010] Preferably, the arc-shaped frame is composed of upper and lower symmetrical arc-shaped plates and left and right symmetrical support columns located between the upper and lower arc-shaped plates. The arc-shaped pressure block and the secondary arc-shaped pressure block are located between the left and right symmetrical support columns, and the connecting rod is made of deformable metal material.
[0011] Preferably, the connecting cylinder is provided with a guide assembly for guiding and resetting the arc-shaped frame. The guide assembly includes through holes that are symmetrically arranged on the lower arc-shaped plate. Guide posts corresponding to the through holes are fixedly installed on the lower end face of the connecting cylinder. Several springs are fixedly installed in an array between the upper arc-shaped plate and the upper ring cover.
[0012] Preferably, a mating rod is fixedly installed inside the arc-shaped pressure block, and a connecting plate symmetrical about the corresponding arc-shaped pressure block is hinged to the mating rod. The connecting plate is hinged to the corresponding support column to accommodate the angle change when the arc-shaped pressure block rotates.
[0013] Preferably, a rubber column located between adjacent arc-shaped frames is fixedly installed on the inner ring wall of the mounting cylinder, and the rubber column is fan-shaped.
[0014] Preferably, the wire fixing mechanism includes a clamp assembly and a gasket. The clamp assembly includes a semi-circular clamp that is disposed below the connecting rod and is symmetrical in front and back. One side of the symmetrical semi-circular clamp is hinged by a pin, and the other side of the symmetrical semi-circular clamp is fixedly connected by two second bolts distributed vertically.
[0015] Preferably, the connecting rod is provided with a connecting component and an installation component. The installation component includes an arc-shaped installation plate disposed on the upper end face of the semi-circular clamp and corresponding to the arc-shaped frame. The arc-shaped installation plate is threaded with a first bolt symmetrical about the corresponding connecting rod. The semi-circular clamp and the arc-shaped installation plate are fixedly connected by the symmetrical first bolts.
[0016] Preferably, the connecting assembly includes through slots formed on the lower end face of the mounting cylinder and corresponding to the connecting rods one by one. Hinges are fixedly installed on the upper end face of the arc-shaped mounting plate and the lower end face of the arc-shaped frame. The connecting rods are ball-hinged with the corresponding arc-shaped mounting plate and arc-shaped frame through the hinges.
[0017] Preferably, the gasket is fixedly installed on the inner ring wall of the semi-circular clamp, and a plurality of rubber protrusions are arranged in an array on the inner ring wall of the gasket.
[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the lever design of the arc-shaped pressure block and the secondary arc-shaped pressure block, the clamping force of the cable is controlled in stages. Under normal conditions, the smaller arc-shaped pressure block provides moderate clamping force to avoid damage to the cable insulation layer due to excessive initial pressure. When the cable is under tension, it automatically switches to the larger secondary arc-shaped pressure block to provide a locking force greater than normal, thereby ensuring the stability of the connector fixing the cable and effectively protecting the cable body. Furthermore, by switching between the two, the unfavorable tensile force is automatically converted into a larger radial compressive force on the sidewall of the cable, so that the cable achieves a self-locking effect of tightening as it is pulled, eliminating the safety hazard of easy loosening under dynamic conditions in traditional fixing methods. At the same time, the circumferential array of arc-shaped frames can respond to tensile forces in different directions and effectively transmit and amplify them, thereby enabling the connector to change from passively bearing external forces to actively using external forces to enhance the reliability of its own fixing.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0031] The terms used in this invention, such as "upper," "lower," "left," "right," "middle," and "one," are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.
[0032] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6A cable connector for a power distribution cabinet includes a cabinet 1 and a fixed housing 2 fixedly installed inside it for connecting cables. A connecting cylinder 3 is fixedly installed inside the fixed housing 2, and several arc-shaped frames 4 that move up and down are arranged in a circumferential array inside the connecting cylinder 3.
[0033] Please see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 9 The arc frame 4 has several arc-shaped pressure blocks 41 arranged in a linear array. The arc-shaped pressure blocks 41 are hinged to the connecting cylinder 3 by a set pin. An inclined secondary arc-shaped pressure block 42 is fixedly installed on the upper end of the arc-shaped pressure block 41. The secondary arc-shaped pressure block 42 is larger than the arc-shaped pressure block 41. The lower end of the arc frame 4 is ball-hinged with a connecting rod 5. The lower ends of several connecting rods 5 are jointly provided with a wire fixing mechanism 6 for fixing to the outer wall of the cable.
[0034] When the cable passes through the connecting cylinder 3, the arc-shaped pressure blocks 41 around the cable press and fix the outer wall of the cable. When the cable is pulled, the cable fixing mechanism 6 tilts and pulls the corresponding arc-shaped frame 4 down through the connecting rod 5. The arc-shaped pressure block 41 rotates and switches to a secondary arc-shaped pressure block 42 to contact the outer wall of the cable, so as to increase the clamping force on the cable by increasing the degree of compression on the force side of the cable through unfavorable external force.
[0035] Among them, cabinet 1 serves as the main structure of the power distribution cabinet, which is used to house and protect the internal electrical components and ensure that the cable connectors can be reliably fixed inside the power distribution cabinet. The fixed outer shell 2 serves as the external support structure for the cable connectors, providing a mounting base for the connecting cylinder 3 and other internal components, and protecting its internal structure from the influence of the external environment.
[0036] The connecting rod 5 transmits the cable tension sensed by the cable fixing mechanism 6 to the arc frame 4, and can adapt to the tilting and pulling of the cable according to the angle change during the transmission process. The cable fixing mechanism 6 directly senses the cable tension and transmits the tension to the arc frame 4 through the connecting rod 5, thereby adaptively clamping.
[0037] In actual operation, when no force is applied, the arc-shaped pressure block 41 is slightly tilted downwards. When the cable is inserted into the connecting cylinder 3, the outer wall of the cable contacts the arc-shaped pressure block 41 and lifts it slightly upwards. At this time, the arc-shaped pressure blocks 41 around the cable are tightly fitted to the outer wall of the cable, thereby applying slight radial pressure to the outer wall of the cable, thus achieving the initial positioning and fixation of the cable.
[0038] When the cable is subjected to external tension, the cable fixing mechanism 6 will move together with the cable. Due to the cooperation between the connecting rod 5, the cable fixing mechanism 6, and the arc frame 4, the tension of the cable will be transmitted to the arc frame 4 through the connecting rod 5. If there is an angle of inclination in the direction of the tension, the ball joint of the connecting rod 5 allows the cable fixing mechanism 6 to change angle, thereby converting the tension into a force that causes the arc frame 4 to move downward.
[0039] As the arc frame 4 descends, the arc-shaped pressure block 41 inside it will rotate around the pin. At this time, the secondary arc-shaped pressure block 42 will gradually contact and press against the outer wall of the cable. Since the secondary arc-shaped pressure block 42 is larger in size than the arc-shaped pressure block 41 and is set at an angle, the contact area and squeezing effect between the secondary arc-shaped pressure block 42 and the cable will be significantly enhanced, thereby converting the cable tension into a larger radial clamping force, effectively preventing the cable from loosening or falling off.
[0040] Furthermore, due to the change in angle of the cable fixing mechanism 6 caused by external tension, the relative compressive force can be applied to different areas of the cable through the arc frame 4 to ensure the cable is fixed.
[0041] Therefore, during the operation of the distribution cabinet, when the cable is subjected to external tension, the adverse external force can be automatically converted into radial clamping force on the cable, solving the problem that the clamping force of the cable connector cannot adapt to changes in the existing technology, reducing safety hazards such as increased contact resistance, overheating or even power failure caused by loose cables, and providing continuous and reliable safety protection for cable connections in the distribution cabinet.
[0042] Please see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The connecting cylinder 3 consists of an upper ring cover 31 at the upper end and a mounting cylinder 32 at the lower end. The pin on the arc-shaped pressure block 41 passes through the outer ring wall of the mounting cylinder 32. The outer walls of both the arc-shaped pressure block 41 and the secondary arc-shaped pressure block 42 are covered with a rubber layer.
[0043] In practical operation, the split structure of the connecting cylinder 3 simplifies the assembly and maintenance process of internal components, improves the maintainability of the distribution cabinet cable connectors, and the pin shaft of the arc-shaped pressure block 41 passes through the outer ring wall of the mounting cylinder 32 to ensure the stability of the arc-shaped pressure block 41 during rotation and switching. The rubber layer increases the friction between the two and the outer wall of the cable, making it less likely for the cable to slip off during the initial fixing stage. When the cable is subjected to adverse external force, the secondary arc-shaped pressure block 42 can provide stronger gripping force when it contacts the cable, converting the tension into a greater squeezing and clamping force, thereby further enhancing the fixing effect and anti-loosening ability of the cable.
[0044] Please see Figure 6 and Figure 7The arc frame 4 is composed of an upper and lower symmetrical arc plate 401 and a left and right symmetrical support column 402 located between the upper and lower arc plates 401. The arc pressure block 41 and the secondary arc pressure block 42 are located between the left and right symmetrical support columns 402. The connecting rod 5 is made of deformable metal material.
[0045] In actual operation, the symmetrical frame structure of the arc frame 4 can ensure that the arc pressure block 41 and the secondary arc pressure block 42 maintain precise positioning and uniform force during rotation switching, avoid pressure block position displacement, and thus ensure uniform clamping effect on the cable.
[0046] The connecting rod 5 is made of deformable metal material, which allows the connecting rod 5 to deform appropriately when the wire fixing mechanism 6 is tilted, effectively absorbing and transmitting tension, ensuring the sensitivity and reliability of the descent action of the arc frame 4, and avoiding poor force transmission or component damage that may be caused by rigid connection.
[0047] Please see Figure 6 and Figure 7 The connecting cylinder 3 is provided with a guide assembly 43 for guiding and resetting the arc frame 4. The guide assembly 43 includes through holes 431 that are symmetrically opened on the lower arc plate 401. The lower end face of the connecting cylinder 3 is fixedly installed with guide posts 432 that correspond one-to-one with the through holes 431. Several springs 433 are fixedly installed between the upper arc plate 401 and the upper ring cover 31 in an array.
[0048] Please see Figure 6 and Figure 7 A mating rod is fixedly installed inside the arc-shaped pressure block 41. A connecting plate 44 symmetrical about the corresponding arc-shaped pressure block 41 is hinged on the mating rod. The connecting plate 44 is hinged to the corresponding support column 402 to accommodate the angle change when the arc-shaped pressure block 41 rotates.
[0049] Please see Figure 4 , Figure 5 and Figure 6 A rubber column 45 located between adjacent arc-shaped frames 4 is fixedly installed on the inner ring wall of the mounting cylinder 32. The rubber column 45 is fan-shaped.
[0050] In actual operation, the through hole 431 and the guide post 432 cooperate to restrict the vertical movement of the arc frame 4, ensuring that it can rise and fall smoothly in the vertical direction and avoid deviation caused by external force. The spring 433 enables the arc frame 4 to automatically return to the initial position after the external tension is released.
[0051] When the cable is subjected to tension and the arc frame 4 descends, it causes the arc pressure block 41 to rotate and switch to the secondary arc pressure block 42 to contact the cable. The cooperating rod serves as the rotation axis of the arc pressure block 41 and works in conjunction with the symmetrically hinged connecting plate 44 to provide stable support and guidance at the hinge point between the connecting plate 44 and the support column 402. This ensures that the rotation process of the arc pressure block 41 is smooth, stable, and the angle change is precise and controllable.
[0052] The rubber column 45 can absorb the impact and minor displacement of the cable during the operation of the distribution cabinet, thereby avoiding hard contact and friction between the cable and the connecting cylinder 3 or the arc frame 4, reducing noise generation. At the same time, the fan-shaped structure of the rubber column 45 allows it to better fit the curved surface of the outer wall of the cable, increasing the contact area and providing more uniform lateral support and clamping force, thereby further enhancing the cable's fixation stability and preventing accidental loosening or displacement. Moreover, under adverse external forces, the fan-shaped rubber column 45 can work in conjunction with the arc-shaped pressure block 41 and the secondary arc-shaped pressure block 42 to jointly improve the overall clamping effect on the cable, thereby ensuring the long-term reliability and safety of the cable connection.
[0053] Please see Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The wire fixing mechanism 6 includes a clamp assembly 61 and a gasket 62. The clamp assembly 61 includes a semi-circular clamp 611 that is disposed below the connecting rod 5 and is symmetrical in front and back. One side of the symmetrical semi-circular clamp 611 is hinged by a pin, and the other side of the symmetrical semi-circular clamp 611 is fixedly connected by two second bolts 612 distributed vertically.
[0054] Please see Figure 8 The gasket 62 is fixedly installed on the inner ring wall of the semi-circular clamp 611, and a number of rubber protrusions 621 are arranged in an array on the inner ring wall of the gasket 62.
[0055] In actual operation, the semi-circular clamp 611 and the second bolt 612 cooperate to facilitate the installation and disassembly of the cable connector. The gasket 62 not only increases the friction but also provides buffer protection between the cable and the clamp, avoiding damage to the cable surface. When the rubber protrusion 621 is subjected to cable compression or external vibration, it can adaptively fit into the outer wall of the cable, thereby generating additional friction to ensure the stability of the cable fixing mechanism 6. When the cable is pulled by external force, the cable fixing mechanism 6 can effectively suppress the displacement of the cable, thereby improving the reliability and anti-loosening effect of cable fixing.
[0056] Please see Figure 4 , Figure 5 , Figure 7 and Figure 8The connecting rod 5 is provided with a connecting component 51 and a mounting component 52. The mounting component 52 includes an arc-shaped mounting plate 521 set on the upper end face of the semi-circular clamp 611 and corresponding to the arc-shaped frame 4. The arc-shaped mounting plate 521 is threaded with a first bolt 522 symmetrical about the corresponding connecting rod 5. The semi-circular clamp 611 and the arc-shaped mounting plate 521 are fixedly connected by the symmetrical first bolts 522.
[0057] Please see Figure 4 , Figure 5 and Figure 8 The connecting component 51 includes a through groove 511 opened on the lower end face of the mounting cylinder 32 and corresponding to the connecting rod 5. The upper end face of the arc-shaped mounting plate 521 and the lower end face of the arc-shaped frame 4 are both fixedly installed with hinge seats 512. The connecting rod 5 is ball-hinged with the corresponding arc-shaped mounting plate 521 and arc-shaped frame 4 through the hinge seats 512.
[0058] In actual operation, the arc-shaped mounting plate 521 cooperates with the first bolt 522 to ensure that the connecting rod 5 can stably transmit the force to the arc-shaped frame 4, thereby causing the arc-shaped pressure block 41 to rotate and switch to the secondary arc-shaped pressure block 42 to increase the clamping force on the cable.
[0059] The through slot 511 provides movement space for the connecting rod 5, ensuring that it can move smoothly during tilting and descent under force. At the same time, the hinge seat 512 is ball-jointed with the connecting rod 5, enhancing the flexibility of the connection point and enabling it to adaptively adjust its posture to match the relative movement and angle changes between the wire fixing mechanism 6 and the arc frame 4. This ensures that the external tension can be efficiently transmitted to the arc frame 4 through the connecting rod 5, ultimately achieving adaptive enhancement of the cable clamping force.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
