Description

Technical Field

[0001] This application relates to the technical field of wire installation, and in particular to a sliding contact type wire trough connection device. Background Technology

[0002] Currently, busbar products in the power transmission and distribution industry are usually assembled with each phase conductor using an insulating component on the outer shell. When the busbar supplies power to electrical equipment, a plug-in box needs to be installed at the connection point. The busbar product shell needs to be opened with plug-in holes to realize the plug-in connection of the plug-in box, and the plug-in hole also needs to be equipped with a tap head.

[0003] This setup not only makes the manufacturing process complicated, but also makes installation and operation troublesome for users. Furthermore, during long-term use, the connection between the plug-in box and the busbar trunking is prone to loosening due to vibration, aging, and other factors, leading to poor contact and potential safety hazards such as overheating and arcing. When maintaining and repairing the busbar trunking connection device, it is necessary to disassemble and reinstall the plug-in box and the busbar trunking, which will consume a lot of time and manpower. Summary of the Invention

[0004] To address the problems of existing power connection devices, this application provides a sliding contact type cable tray power connection device, which simplifies the device structure and improves ease of operation.

[0005] This application provides a sliding contact type cable tray power connection device, which adopts the following technical solution: A sliding contact type cable tray power connection device, comprising: The main frame includes a plug-in slot that penetrates one side wall. A live wire latch, a neutral wire latch, and a ground wire latch are respectively fixed on the three inner side walls of the main frame, such that the live wire latch and the neutral wire latch are arranged on opposite inner side walls, and the ground wire latch is arranged on the inner side wall opposite to the opening of the plug-in slot. A busbar assembly includes at least two busbars and one grounding busbar, wherein one of the busbars is engaged in the live wire engagement part, one of the busbars is engaged in the neutral wire engagement part, and the grounding busbar is engaged in the ground wire engagement part; The power connection mounting base contains electrical components, a live wire, a neutral wire, and a ground wire. The live wire, neutral wire, and ground wire are connected to the electrical components to realize the circuit connection of the electrical components. A sliding plug is located on one side of the power connection mounting base. The sliding plug is detachably connected to the plug slot. The live wire, neutral wire, and ground wire all pass through the sliding plug, and each of the three wires has a conductive contact fixed at its end. The conductive contact connected to the live wire contacts the busbar that is snapped into the live wire snap-in part, the conductive contact connected to the neutral wire contacts the busbar that is snapped into the neutral wire snap-in part, and the conductive contact connected to the ground wire contacts the grounding busbar that is snapped into the ground wire snap-in part. The conductive contacts are not arranged in parallel on the same extension line.

[0006] By adopting the above technical solutions, the structure of the device is cleverly improved, making it more simplified. The sliding plug and the socket are detachably connected, making the connection more flexible and improving the ease of assembly and disassembly. At the same time, the conductive contacts of the live wire, neutral wire, and ground wire are not arranged in parallel on the same extension line, which can realize independent power connection of the three-phase circuit and avoid mutual interference between circuits, further improving electrical safety. Moreover, the contact connection method between the conductive contacts and the busbar and grounding busbar, compared with the traditional connection method of the socket box and busbar trunking, can effectively reduce the loosening problems caused by vibration, aging and other factors, reduce the safety hazards such as overheating and arcing caused by poor contact, and achieve the effect of enhancing the user's electrical safety and simplifying operation.

[0007] Preferably, the power mounting base has a connection port on the side near the sliding joint, and the connection port has a groove recessed around its wall. The sliding plug includes a T-shaped insert plate, which is inserted into the groove.

[0008] By adopting the above technical solution, the cooperation between the T-shaped plug and the slot makes the connection between the sliding plug and the power mounting base more stable, which helps to reduce the possibility of loosening or falling off during use, and further improves the reliability and stability of the device. At the same time, the slot can limit the plug, ensuring that the plug is accurately inserted into the designated position, and ensuring that the two will not separate when the sliding plug undergoes an angle change within the main frame. This ensures that the conductive contacts of the live wire, neutral wire, and ground wire can always accurately contact and connect to the corresponding busbar and grounding busbar, reducing the risk of poor contact.

[0009] Preferably, the sliding connector includes a first connecting cover, a second connecting cover, and a locking member. The first connecting cover and the second connecting cover are connected by the locking member, and a storage cavity is formed between the first connecting cover and the second connecting cover. The live wire, neutral wire, and ground wire all pass through the storage cavity.

[0010] By adopting the above technical solution, the first and second connecting covers are connected by a locking mechanism, which facilitates the installation, inspection, and maintenance of the wiring inside the storage cavity. When it is necessary to inspect or replace the wiring, simply open the locking mechanism to easily open the connecting cover for operation, which improves the maintainability of the device. Moreover, placing the live wire, neutral wire, and ground wire inside the storage cavity can protect the wiring, prevent it from being interfered with or damaged by external factors, and extend the service life of the wiring.

[0011] Preferably, the sliding joint includes at least three guide plug portions, and the conductive contact slides on the guide plug portions.

[0012] By adopting the above technical solution, the guide plug can provide accurate guidance for the sliding of the conductive contact, so that the conductive contact remains stable during the sliding process, ensuring more reliable contact between the conductive contact and the busbar and grounding busbar, reducing the occurrence of poor contact due to offset during the sliding process. Moreover, the guide plug can also play a certain protective role for the conductive contact, preventing the conductive contact from being damaged by collision or friction during the sliding process, further improving the stability and reliability of the device.

[0013] Preferably, a locking mechanism is provided between the power connection mounting base and the sliding plug to improve the connection capability between the sliding plug and the main frame.

[0014] Preferably, the locking mechanism includes a pressing slider and an elastic element. The pressing slider is slidably mounted on the sliding plug and is arranged on the side close to the power connection mounting base. One end of the elastic element is fixed to the sliding joint and the other end is fixed to the pressing slider. The side of the pressing slider away from the power connection mounting base presses against the main frame.

[0015] By adopting the above technical solution, when the sliding plug's insert plate is inserted into the slot of the power connection mounting base, the sliding connector is also inserted into the main frame. The pressing slider always maintains a tight pressing state with the main frame. At this time, the elastic element has an elastic deformation that returns to the direction closer to the power connection mounting base, which makes the pressing slider further press the main frame, enhancing the connection stability between the sliding plug and the main frame. This connection method can effectively prevent the sliding plug from shaking or loosening during use, ensuring that the conductive contacts and the busbar and grounding busbar always maintain good contact, reducing safety hazards caused by loose connections.

[0016] Meanwhile, the locking mechanism is adjustable. When the sliding plug needs to be disassembled or replaced, simply overcome the elastic force of the elastic element and slide the pressing slider a certain distance away from the main frame to easily release the lock between the sliding plug and the main frame. When installing the sliding plug, the elastic element will automatically push the pressing slider towards the main frame to achieve fast and reliable locking.

[0017] Preferably, both the live wire connector and the neutral wire connector are U-shaped structures, with the opening of the U-shaped structure facing the interior of the main frame, and the two ends of the busbar abutting against the opposite side walls of the U-shaped structure.

[0018] Preferably, the live wire latch, the neutral wire latch, and the ground wire latch all have a limiting part.

[0019] By adopting the above technical solution, the U-shaped structure can provide a stable snap-fit ​​space for the busbar. The two ends of the busbar abut against the opposite side walls of the U-shaped structure, realizing the installation of the busbar within the main frame. The limiting part can limit the busbar and the grounding busbar, ensuring that they are accurately installed in the corresponding snap-fit ​​parts and will not shift or shake during use. This helps to ensure good contact between the subsequent conductive contacts and the busbar and the grounding busbar, improving the stability and reliability of the connection.

[0020] Preferably, the live wire connector, neutral wire connector, and ground wire connector all have heat dissipation parts.

[0021] By adopting the above technical solution, the heat dissipation unit can dissipate the heat generated by the busbar and grounding busbar during the power-on process in a timely manner, preventing the temperature from becoming too high due to heat accumulation, thereby avoiding damage to the snap-fit ​​part and the conductive busbar, helping to reduce the risk of electrical safety accidents and ensuring the electrical safety of users.

[0022] Preferably, the main frame has multiple live wire connectors and multiple neutral wire connectors, with the live wire connectors arranged side by side along one side of the main frame and the neutral wire connectors arranged side by side along the other side of the main frame. At the same time, each live wire connector and each neutral wire connector is connected to a busbar.

[0023] Preferably, an insulating part is provided between two adjacent live wire connectors and between two adjacent neutral wire connectors.

[0024] By adopting the above technical solution, the setting of multiple live wire and neutral wire connectors can meet different power needs. Users can insert them in either direction according to actual needs, and can choose the busbars in the live wire and neutral wire connectors of different heights for power connection, which greatly improves the applicability and flexibility of the device.

[0025] The insulation can block the conduction of current between adjacent busbars, ensuring the independence and safety of each circuit. This effectively prevents leakage between adjacent busbars, avoiding safety problems such as short circuits and fires caused by leakage, and further improving the electrical safety of the device.

[0026] Preferably, connecting rails are fixed on opposite side walls of the main frame, the extension direction of the connecting rails is consistent with the length direction of the main frame, and the bottom surfaces of the sliding plug are slidably connected to the corresponding connecting rails.

[0027] Preferably, the main frame has two limiting rails fixed on the side near the opening of the insertion slot, and the connecting rails on the same side of the limiting rails are directly opposite each other, and the top surfaces of the two sides of the sliding plug are respectively slidably connected to the corresponding limiting rails.

[0028] By adopting the above technical solution, the connecting rail provides an accurate track for the sliding plug, enabling the sliding plug to slide smoothly and steadily along the length of the main frame. At the same time, with the cooperation of the limiting rail, the vertical movement of the sliding plug can be effectively restricted, preventing the sliding plug from wobbling up and down or detaching from the connecting rail during the sliding process. This makes the sliding of the sliding plug within the main frame more precise, helping to ensure that the conductive contacts maintain good contact with the busbar and grounding busbar at all times, thus ensuring the stability of the power connection.

[0029] In addition, this structural design makes it easier for users to operate the sliding plug. Users can easily slide the sliding plug along the connecting rail and the limiting rail to the desired position to achieve quick power connection or disconnection, thus improving the ease of use of the device.

[0030] Preferably, the main frame is covered with a shielding shell.

[0031] By adopting the above technical solution, the shielding shell can effectively shield external electromagnetic interference, prevent external electromagnetic signals from affecting the internal circuits of the device, ensure the normal operation of the device, and at the same time, it can play a certain role in protecting the main frame, preventing the main frame from being affected by external factors such as collisions, dust, and moisture, and extending the service life of the device.

[0032] Preferably, both the main frame and the shielding shell are provided with weight-reducing parts.

[0033] By adopting the above technical solutions, the weight reduction section can effectively reduce the weight of the device without affecting the structural strength of the main frame and shielding shell, thereby reducing the production and transportation costs of the device.

[0034] In summary, this application includes at least one of the following beneficial technical effects: 1. The device's structure has been cleverly improved, making it more simplified. The sliding plug and the socket are detachably connected, making the connection more flexible and improving the ease of assembly and disassembly. At the same time, the conductive contacts of the live wire, neutral wire, and ground wire are not arranged in parallel on the same extension line, which can realize independent power connection of the three-phase circuit and avoid mutual interference between circuits, further improving electrical safety. Moreover, the contact connection method between the conductive contacts and the busbar and grounding busbar, compared with the traditional connection method of the socket box and busbar trunking, can effectively reduce the loosening problems caused by vibration, aging and other factors, reduce the safety hazards such as overheating and arcing caused by poor contact, and achieve the effect of enhancing the user's electrical safety and simplifying operation. 2. The T-shaped plug and the slot make the connection between the sliding plug and the power mounting base more secure, which helps to reduce the possibility of loosening or falling off during use, and further improves the reliability and stability of the device. At the same time, the slot can limit the plug, ensuring that the plug is accurately inserted into the designated position. It also ensures that the two will not separate when the sliding plug changes angle within the main frame, so that the conductive contacts of the live wire, neutral wire and ground wire can always accurately contact and connect to the corresponding busbar and grounding busbar, reducing the risk of poor contact. 3. When the sliding plug's insert plate is inserted into the slot of the electrical mounting base, the sliding connector is also inserted into the main frame. The pressing slider always maintains a tight pressing state with the main frame. At this time, the elastic element has an elastic deformation that returns towards the electrical mounting base, causing the pressing slider to further press the main frame, which enhances the connection stability between the sliding plug and the main frame. This connection method can effectively prevent the sliding plug from shaking or loosening during use, ensuring that the conductive contacts and the busbar and grounding busbar always maintain good contact, reducing safety hazards caused by loose connections.

Detailed Implementation

[0042] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0043] This application discloses a sliding contact type cable tray power connection device.

[0044] Reference Figure 1 and Figure 2 A sliding contact type cable tray power connection device includes a main frame 1, a conductive busbar 2, a power connection mounting base 3, and a sliding plug 4. The main frame 1 provides support and a mounting foundation for the entire device. The conductive busbar 2 transmits current. The power connection mounting base 3 is used to install electrical components and achieve circuit connection. The sliding plug 4 connects to both the main frame 1 and the power connection mounting base 3, and can slide within a slot in the main frame 1 to achieve power connection. Compared to traditional plug-in methods, the sliding contact power connection method of the sliding plug 4 reduces the complexity of the plug-in structure and installation steps, while maintaining more stable contact with the conductive busbar 2, thus improving the reliability and safety of the power connection.

[0045] Specifically, the main frame 1 includes a plug-in slot that runs through one side wall. The main frame 1 is made of plastic with good insulation properties, which can effectively prevent current leakage and ensure electrical safety. A live wire latch 11, a neutral wire latch 12, and a ground wire latch 13 are respectively fixed on the three inner side walls of the main frame 1. The live wire latch 11 and the neutral wire latch 12 are located on opposite inner side walls, and the ground wire latch 13 is located on the inner side wall opposite the opening of the plug-in slot. This layout makes the latching parts of the three-phase circuit reasonably distributed, facilitating the subsequent installation of the conductor busbar 2 and the connection operation of the sliding plug 4.

[0046] Furthermore, the main frame 1 has two live wire connectors 11 and two neutral wire connectors 12. The two live wire connectors 11 are arranged side by side along one side of the main frame 1, and the two neutral wire connectors 12 are arranged side by side along the other side of the main frame 1, so that the two live wire connectors 11 and the two neutral wire connectors 12 are symmetrically arranged along the center line of the main frame 1. Insulating portions 16 are provided between two adjacent live wire latches 11 and between two adjacent neutral wire latches 12. Specifically, the insulating portion 16 can be an insulating plastic partition. Placing the insulating plastic partition between adjacent live wire latches 11 and neutral wire latches 12 can ensure that each circuit remains independent. Alternatively, the insulating portion 16 can be a partition groove formed between two neutral wire latches 12 or two live wire latches 11, which can reliably block the conduction of current between adjacent busbars 21 and effectively avoid short circuits caused by leakage. In this embodiment, the partition groove is used as the insulating portion 16 to reduce production costs. At the same time, the partition groove can also serve as a sliding groove, which is beneficial for the subsequent sliding engagement of the sliding plug 4 and the main frame 1.

[0047] In this application, the busbar group 2 includes a busbar 21 and a grounding busbar 22, such that a busbar 21 is snapped into each live wire snap-in part 11 and each neutral wire snap-in part 12, and a grounding busbar 22 is snapped into the ground wire snap-in part 13. Both the busbar 21 and the grounding busbar 22 are made of high-purity copper, which has good conductivity and thermal conductivity and can efficiently transmit current.

[0048] Specifically, the live wire latch 11, neutral wire latch 12, and live wire latch 13 are all U-shaped structures, with the openings of the U-shaped structures facing inwards towards the main frame 1. Furthermore, each of these three terminals has a limiting part 14. During installation, the two ends of the busbar 21 abut against the opposite side walls of the U-shaped structure, and the two ends of the grounding busbar 22 also abut against the corresponding opposite side walls of the U-shaped structure. The limiting part 14 can be a protrusion or a groove, used to restrict the position of the busbar assembly 2 and prevent displacement during use. Users can adapt the structure of the live wire latch 11, neutral wire latch 12, and live wire latch 11 according to the specific shape and structure of the actual busbar assembly 2, for example, by using a C-shaped structure or other similar latching structures to ensure stable installation of the busbar assembly 2.

[0049] In this application, these snap-fit ​​parts also have heat dissipation parts (not shown in the figure). The heat dissipation parts are heat dissipation grooves or heat dissipation holes opened on the side of the snap-fit ​​part away from the interior of the main frame 1, which helps to dissipate the heat generated by the conductive busbar 2 and improve the safety of the device.

[0050] To shield against electromagnetic interference, refer to Figure 1 and Figure 3 The outer wall of the main frame 1 is covered with a shielding shell 7, which can be made of metal. The outer wall of the main frame 1 has an installation groove, which is a U-shaped groove on the top surface of the main frame 1. There are at least two installation grooves symmetrically opened along the center line of the main frame 1. The shielding shell 7 fits perfectly with the outer contour of the main frame 1. The two ends of the shielding shell 7 are hooked to the corresponding installation grooves.

[0051] Furthermore, both the main frame 1 and the shielding shell 7 are provided with weight-reducing sections 15. These weight-reducing sections 15 can be weight-reducing grooves without any partitioning, reducing weight while ensuring device strength. Specifically, the weight-reducing sections 15 of the main frame 1 can be located on the left and right sides of the live wire connection 11, neutral wire connection 12, and ground wire connection 13, achieving both weight reduction and blocking current conduction between adjacent busbars 21. The weight-reducing sections 15 of the shielding shell 7 can be located on the side away from the mounting groove of the main frame 1. The shielding shell 7, while completely covering the outer wall of the main frame 1, forms an I-beam structure, effectively shielding against electromagnetic interference and minimizing the overall weight of the device while ensuring sufficient strength.

[0052] To achieve the connection between the sliding plug 4 and the main frame 1, refer to... Figure 1 and Figure 3Connecting rails 17 are fixed on opposite side walls of the main frame 1. The extension direction of the connecting rails 17 is consistent with the length direction of the main frame 1. Two limiting rails 18 are fixed on the side of the main frame 1 near the opening of the insertion slot. The connecting rails 17 on the same side of the limiting rails 18 are directly opposite each other. Specifically, one connecting rail 17 and one limiting rail 18 on the same side are arranged vertically opposite each other.

[0053] Reference Figure 4 and Figure 5 The power connection mounting base 3 is generally made of plastic and has an internal cavity for storing parts. It possesses good insulation performance and structural strength. In this application, the power connection mounting base 3 houses electrical components, a live wire 61, a neutral wire 62, and a ground wire 63. These wires are connected to the electrical components to achieve circuit connection. A connection port 31 is provided on the side of the power connection mounting base 3 near the sliding connector. The connection port 31 has recessed grooves 32 along its wall for connecting to the sliding plug 4.

[0054] The sliding connector includes a first connecting cover 41, a second connecting cover 42, and a locking member 43. The first connecting cover 41 and the second connecting cover 42 are connected by the locking member 43. A storage cavity is formed between the first connecting cover 41 and the second connecting cover 42. The live wire 61, the neutral wire 62, and the ground wire 63 all pass through the storage cavity. The locking member 43 can be a locking screw. The user only needs to tighten the locking screw to make the first connecting cover 41 and the second connecting cover 42 tightly connected, ensuring the stability of the circuit in the storage cavity.

[0055] Furthermore, a large insert post is fixed to the side of the first connecting cover 41 near the second connecting cover 42, and a guide hole is passed through the middle of the large insert post. A guide insert post that matches the guide hole is fixed to the side of the second connecting cover 42 near the first connecting cover 41. When the first connecting cover 41 and the second connecting cover 42 are connected, the guide insert post is first inserted into the guide hole to achieve positioning, thereby improving the accuracy of the connection between the two. Then, the locking piece 43 is used to lock the two together, thereby improving the installation stability of the two.

[0056] After the first connecting cover 41 and the second connecting cover 42 are fixed, a T-shaped insert plate 44 and a rectangular connector 45 are formed. When the sliding connector is assembled with the power connection mounting base 3, the insert plate 44 is inserted into the slot 32. The fit between the two is a clearance fit, so that the angle between the two can change when the user rotates the power connection mounting base 3. The connector 45 is fixed at one end of the insert plate 44 near the main frame 1. A clearance rounded corner 451 is provided on the outer wall of the connector 45. Two clearance rounded corners 451 are set at two diagonally opposite corners of the connector 45. A mating groove 471 is provided at one of the corners with the rounded corner. Two L-shaped connecting grooves 472 are formed between the insert plate 44 and the connector 45. The two connecting grooves 472 are symmetrically arranged along the center line of the connector 45. In addition, a reinforcing slider 46 is fixed on the outer wall of the connector 45 on the side away from the mating groove 471.

[0057] In this application, the live wire 61, neutral wire 62, and ground wire 63 are led out from inside the power connection mounting base 3, passing through the connection port 31 of the power connection mounting base 3 and the storage cavity of the sliding joint. The ends of the three are all fixed with conductive contacts 64. A guide insertion part is provided on the side wall of the sliding joint. The sliding joint includes at least three guide insertion parts. The conductive contacts 64 slide on the guide insertion parts. The guide insertion parts can be insertion holes. After the conductive contacts 64 pass through the guide insertion parts from the storage cavity, the conductive contacts 64 connected to the live wire 61 make contact with the busbar 21 that is locked in the live wire locking part 11, the conductive contacts 64 connected to the neutral wire 62 make contact with the busbar 21 that is locked in the neutral wire locking part 12, and the conductive contacts 64 connected to the ground wire 63 make contact with the grounding busbar 22 that is locked in the ground wire locking part 13. They are not arranged in parallel on the same extension line.

[0058] In application, the user first inserts the sliding plug 4 into the insertion slot of the main frame 1, and rotates it 90° around the trajectory of the sliding plug 4 with the avoidance rounded corner 451 until the two connecting grooves 472 are slidably connected to the two limiting rails 18 respectively. The mating grooves 471 slide into the connecting rails 17, and the reinforcing slider 46 extends into the partition groove of the insulating part 16 that is close to it, and the two also slide into each other. At this time, the three conductive contacts 64 can make good contact with the corresponding busbar 21 and grounding busbar 22 respectively to achieve power connection.

[0059] Reference Figure 6A locking mechanism 5 is provided between the power connection mounting base 3 and the sliding plug 4 to improve the connection capability between the sliding plug 4 and the main frame 1. Specifically, the locking mechanism 5 includes a pressing slider 51 and an elastic element 52. The pressing slider 51 is slidably mounted on the sliding plug 4 and is arranged on the side close to the power connection mounting base 3. One end of the elastic element 52 is fixed to the sliding connector and the other end is fixed to the pressing slider 51. The side of the pressing slider 51 away from the power connection mounting base 3 presses against the main frame 1.

[0060] More specifically, an assembly cavity is provided at the corner of the electrical mounting base 3. The opening of the assembly cavity is in the same direction as the opening of the connection port 31. A moving rail is fixed on the assembly cavity. The pressing slider 51 is a Z-shaped slider, which slides against the sliding slider and the inner wall of the assembly cavity at the same time. At the same time, a guide groove is also provided through the pressing slider. The extension direction of the guide groove is perpendicular to the movement direction of the pressing slider 51. A guide post 53 is fixed in the assembly cavity. The guide post 53 passes through the guide groove and is used to guide and limit the pressing slider. The elastic element 52 can be a spring, with one end of the spring fixed to the sliding joint and the other end fixed to the pressing slider 51. The extension and contraction direction of the elastic element 52 is consistent with the movement direction of the pressing slider 51.

[0061] After the sliding plug 4 is assembled with the main frame 1, the side wall of the pressing slider 51 presses against the surface of the main frame 1. At this time, the elastic element 52 is in a compressed state. Due to the restriction of the insertion plate 44 of the sliding plug 4 and the slot 32 of the power connection mounting base 3, the elastic element 52 has the elastic deformation to recover towards the power connection mounting base 3, so that the pressing slider 51 further presses the main frame 1, which enhances the connection stability between the sliding plug 4 and the main frame 1. This connection method can effectively prevent the sliding plug 4 from shaking or loosening during use, and ensure that the conductive contact 64 and the busbar 21 and the grounding busbar 22 always maintain good contact, reducing the safety hazards caused by loose connection.

[0062] The above are all preferred embodiments of this application. These embodiments are merely explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of this application should be covered within the scope of protection of this application.
