[0015] The following will be based on embodiments of the present invention. Figures 1-8 The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.
[0016] It should be noted that the "electrical connection" described in this invention refers to the conduction of current between two conductors through direct contact or indirect coupling, such as by connecting them with wires, or by transmitting current through conductive adhesive, welding, etc., all of which fall within the scope of the "electrical connection" of this invention.
[0017] like Figures 1-4 This invention proposes a connector structure for a flow-feeding rail, wherein an electrical connection is achieved between two adjacent flow-feeding rails via a connector; the connector includes a socket end 3 and a plug end 4; The socket end 3 includes a socket housing 301, a socket cover plate 302, and a socket cable 5; The plug end 4 includes a plug housing 401, a plug cover plate 402, and a plug cable 6; Both the socket housing 301 and the plug housing 401 are provided with through holes for the flow rails to pass through. The first flow rail 1 passes through the through hole of the socket housing 301, and the second flow rail 2 passes through the through hole of the plug housing 401. The first and second flow rails are coaxially connected. Both the socket housing 301 and the plug housing 401 are provided with openings on their sides, and the flow rails are located in the openings. The socket housing 301 is detachably connected to the socket cover plate 302 on the side away from its opening, and the socket cable 5 is installed between the socket housing 301 and the socket cover plate 302; the plug housing 401 is detachably connected to the plug cover plate 402 on the side away from its opening, and the plug cable 6 is installed between the plug housing 401 and the plug cover plate 402. When the socket end 3 and the plug end 4 are inserted into each other, the opposite ends of the socket cable 5 and the plug cable 6 are used for plugging and mating to achieve electrical connection, and the opposite ends are respectively electrically connected to the first current supply rail 1 and the second current supply rail 2.
[0018] The current-feeding rails are existing technology. For ease of description, two adjacent current-feeding rails in a row along the axial direction are described as the first current-feeding rail 1 and the second current-feeding rail 2. The specific implementation requires two rows of current-feeding rails, with an induction linear motor installed between them. The carbon brushes of the induction linear motor obtain a continuous and stable current from the two current-feeding rails during sliding. That is, the induction linear motor, the current-feeding rails on both sides of the induction linear motor, the connector, and the power supply together constitute an electrical circuit. Arc-shaped slots are provided on opposite sides of the socket housing 301 and the socket cover 302 to secure the socket cable 5. Arc-shaped slots are also provided on opposite sides of the plug housing 401 and the plug cover 402 to secure the plug cable 6.
[0019] In this invention, the openings in the socket housing 301 and the plug housing 401 provide space for the carbon brush to move, preventing interference and allowing multiple current-carrying rails to connect continuously and without obstruction. When two adjacent current-carrying rails are installed and connected, the socket end 3 and the plug end 4 are interlocked, so that the opposite ends of the socket cable 5 and the plug cable 6 are connected to form an electrical connection between the first current-carrying rail 1 and the second current-carrying rail 2. Disassembly is achieved by reversing the operation. The ends of the socket cable 5 and the plug cable 6 are respectively connected to the socket 501 and the plug 601, which are interlocked to form an electrical connection.
[0020] This invention uses a cable plug-in method to replace the traditional contact conductivity of the current-receiving rail. Electrical connection is achieved through the plugging of the socket cable 5 and the plug cable 6, avoiding the wear and contact resistance problems caused by direct contact with the current-receiving rail. The electrical connection reliability of this invention is higher, reducing contact loss. Moreover, it is convenient to install and maintain, and can realize modular and rapid docking of the current-receiving rail. It avoids the wear problems of traditional contact conductivity and extends the service life of the current-receiving rail.
[0021] Furthermore, the end of the plug end 4 is provided with a plug portion 407, and the end of the socket end 3 is provided with a recessed portion 304, and the plug portion 407 is used to be inserted into the recessed portion 304. The opposite ends of the first current-feeding rail 1 and the second current-feeding rail 2 are used to abut against the insulating baffle 406. The opening is formed on the side of both the plug housing 401 and the plug portion 407. The insulating baffle 406 is located inside the opening of the plug portion 407. The end of the plug cable 6 passes through the insulating baffle 406.
[0022] Both the plug housing 401 and the plug cover 402 have insertion portions at their ends, forming a joint 407. During connection, the joint 407 of the plug end 4 is aligned with the recess 304 of the socket end 3 and inserted. The opposite ends of the first current-carrying rail 1 and the second current-carrying rail 2 abut against the insulating baffle 406. The plug cable 6 passes through the insulating baffle 406 and is then connected to the socket cable 5. The joint 407 and the recess 304 provide a positioning function, and the plug cable 6 limits the movement of the insulating baffle 406. The insulating baffle 406 separates the first current-carrying rail 1 and the second current-carrying rail 2, ensuring that they can only be electrically connected via cable conduction, avoiding contact loss from direct contact and preventing the generation of electric arcs or sparks. The cross-sectional structure of the insulating baffle 406 is the same as that of the current-carrying rails to form a continuous connection structure and avoid structural interference.
[0023] Furthermore, a mounting groove 405 is provided on the side of the plug housing 401 away from its opening, and a locking block 403 is provided in the mounting groove 405; the locking block 403 has a "U" shaped structure, with a wedge-shaped part and a pressing part at its two ends respectively; the opening end face of the plug housing 401 is provided with a first square hole adapted to the pressing part, and the opening end face of the plug part 407 is provided with a second square hole adapted to the wedge-shaped part; the wedge-shaped part extends through the second square hole, and the pressing part extends through the first square hole; an elastic member 404 is provided between the locking block 403 and the plug cover plate 402; The socket housing 301 has an opening end face with a limiting hole that matches the wedge-shaped part. When the plug part 407 is inserted into the recessed part 304, the wedge-shaped part passes through the limiting hole.
[0024] During mating, the insertion part 407 is inserted into the recessed part 304. The wedge-shaped part slides along the opening end face of the socket housing 301 during insertion, eventually passing through the limiting hole to achieve locking. To unlock, press the pressing part; the wedge-shaped part retracts into the second hole, allowing the insertion part 407 to be pulled out of the recessed part 304. The elastic component 404 provides both locking and reset functions. The elastic component 404 can be a common elastic element such as a spring or elastic rubber. Locking by the locking block 403 effectively prevents the connector from accidentally dislodging under vibration or other operating conditions; locking and unlocking operations are simple and quick, facilitating installation and maintenance.
[0025] Furthermore, multiple socket cables 5 and plug cables 6 are provided vertically along the first and second flow rails. In this embodiment, as shown... Figure 1 Three current-carrying rails are arranged vertically side by side. Three rails are also provided for the socket cable 5 and the plug cable 6 respectively; the multiple sets of current-carrying rails are arranged in parallel with the cables to increase the conductive cross-sectional area and improve the overall current-carrying capacity.
[0026] based on Figures 1-4 In this implementation method, since the flow rail is affected by vibration, temperature, etc. during operation, it is necessary to test the connection performance of the connector. To facilitate testing, the present invention also proposes the following improvements: like Figure 5 The present invention also includes a detection mechanism 7, which is used to detect the electrical connection performance of the socket cable 5 and the plug cable 6. It should be noted that three detection mechanisms 7 are provided, corresponding to three sets of socket cables 5 and plug cables 6. Electrical connection performance refers to electrical continuity performance, that is, whether each set of cables suffers from poor contact or open circuit due to vibration, temperature, oxidation, etc. The present invention can detect the connection status of each set of cables through the detection mechanism 7, ensuring a stable and reliable conductive path.
[0027] Furthermore, the detection mechanism 7 includes an insulating housing 701 and two connecting components; The insulating housing 701 is detachably connected to the side of the socket cover 302 and the plug cover 402 away from the current supply rail; the socket cover 302 and the plug cover 402 are respectively provided with mounting holes; one end of each of the two connecting components is respectively disposed in the mounting holes of the socket cover 302 and the plug cover 402. The connecting assembly includes a conductive pin 703 and a conductive bushing 704; the conductive bushing 704 is disposed in the mounting hole, and the conductive pin 703 is inserted into the conductive bushing 704; the socket cable 5 and the plug cable 6 are respectively electrically connected to one of the conductive bushings 704; The electrical connection performance of the socket cable 5 and the plug cable 6 is determined by detecting the current between the two conductive pins 703.
[0028] The conductive bushing 704 and the corresponding cable core can be connected by welding, wire connection, or other methods to form a parallel structure. By measuring the current between the two conductive pins 703, the electrical connection between the socket cable 5 and the plug cable 6 can be determined to be normal.
[0029] Furthermore, an insulating sleeve 705 is provided inside the mounting hole and fitted onto the conductive pin 703.
[0030] The detection of each group of cables in this invention includes, but is not limited to, the following two implementation methods: Implementation method 1, such as Figure 5 The insulating housing 701 has two detection holes, and the end of the conductive pin 703 is disposed in the corresponding detection hole. The opening of the detection hole is connected to an insulating bolt 702. During testing, the insulating bolt 702 is unscrewed, and the probe of the testing device (multimeter) is inserted into the detection hole to contact the end of the conductive pin 703 for testing. After testing, the insulating bolt 702 is screwed on to close the detection hole. In specific implementation, as follows... Figure 7 The two probes of the multimeter can be touched to one of the conductive pins 703 and the corresponding current-carrying rail respectively. This test checks whether the electrical connection between the cable and the current-carrying rail is unobstructed; if... Figure 8 The two probes of the multimeter are respectively connected to the two conductive pins 703. This test checks whether the electrical connection of the cable mating contact is unobstructed. Implementation method 1 can achieve rapid testing of connectors. By manually checking each connector one by one, problems such as poor connection or open circuit can be detected in a timely manner.
[0031] Implementation method 2 is a further improvement on implementation method 1, such as... Figure 6 The detection mechanism 7 also includes an outer cover plate 706 and an intermediate conductive component 11; the outer side of the insulating shell 701 is provided with a groove, the outer cover plate 706 is provided with a protrusion, the protrusion is inserted into the groove, and the insulating shell 701 and the outer cover plate 706 are detachably connected. The two connecting components are symmetrically arranged. Each connecting component further includes a conductive metal plate 714, a conductive metal post 707, a conductive metal sheet 708, a Y-shaped conductive metal block 710, and a conductive connector 711. The end of the conductive pin 703 abuts against the conductive metal plate 714. The conductive metal plate 714 is electrically connected to the conductive metal post 707. The side of the conductive metal post 707 is electrically connected to the conductive metal sheet 708. The conductive metal sheet 708 is inserted into the opening of the Y-shaped conductive metal block 710 and is electrically connected. The conductive metal plate 714, the conductive metal pillar 707, and the conductive metal sheet 708 are all disposed inside the insulating housing 701. One end of the conductive metal sheet 708 protrudes from the inner side of the insulating housing 701 and is located in the groove, so that when the outer cover plate 706 is installed, the end of the conductive metal sheet 708 is inserted into the opening of the Y-shaped conductive metal block 710. The conductive metal sheets 708 of the two connecting components are arranged opposite to each other. The Y-shaped conductive metal blocks 710 of the two connecting components are respectively disposed on both sides of the protrusion of the outer cover plate 706. The opposite sides of the two Y-shaped conductive metal blocks 710 are respectively electrically connected to the conductive connector 711. The intermediate conductive component 11 is disposed inside the protruding portion of the outer cover plate 706. The two ends of the intermediate conductive component 11 are electrically connected to the conductive connector 711 respectively. An overload protection device 8, a resistor device 9 and a current detection device 10 are electrically connected in sequence on the intermediate conductive component 11.
[0032] Overload protection 8, resistive device 9, and current detection device 10 are existing technologies. Overload protection 8 can be common overload protection components such as fuses and circuit breakers; resistive device 9 can be common resistive elements such as resistance wires and resistance sheets, the purpose of which is to limit the current magnitude by connecting resistors in series, reduce the branch current, and reduce losses; current detection device 10 can be devices capable of measuring current magnitude such as ammeters and current sensors. Intermediate conductive component 11 can be common conductive elements such as wires and busbars.
[0033] This invention includes two parallel circuits. One circuit, containing the intermediate conductive component 11, is called a branch circuit. The other circuit, containing the socket and plug cables, is called the main circuit. Specifically, the resistances of the main circuit and branch circuit can be calculated or experimentally obtained. Since the main circuit and branch circuit are connected in parallel, according to the characteristics of parallel circuits, the total current equals the sum of the currents in the main circuit and branch circuits, and the voltages in each branch circuit are equal. By rationally designing the resistance value of the resistor 9, the current ratio between the main circuit and branch circuits can be effectively distributed, ensuring the conductivity of the main circuit while also enabling current monitoring and overload protection functions through the branch circuits. Furthermore, by detecting the branch circuit current through the current detection device 10, the magnitude of the main circuit current can be obtained, thereby determining whether the electrical connection performance of the socket cable 5 and plug cable 6 is normal. When the branch circuit current exhibits abnormal fluctuations or exceeds the set range, it can be inferred that there are problems such as poor contact, open circuit, or overload in the main circuit cable connection. At this time, an alarm device can be triggered to prompt maintenance personnel to inspect and repair.
[0034] When installing the outer cover plate 706, its protruding part is inserted into the groove of the insulating shell 701, and the end of the conductive metal sheet 708 is inserted into the opening of the Y-shaped conductive metal block 710, so that the two connecting components form a detection circuit through the Y-shaped conductive metal block 710, the conductive connector 711, and the intermediate conductive component 11. The overload protection 8, the resistor 9, and the current detection device 10 are connected to the circuit in sequence. During detection, the current detection device 10 measures the circuit current to determine the electrical connection performance, and the overload protection 8 cuts off the circuit when the current is too high. The detection function of Embodiment 2 is more complete, with overload protection, improving detection safety, and enabling unmanned and automated detection. When the number of current-feeding rails is large, Embodiment 2 can significantly improve detection efficiency compared to Embodiment 1.
[0035] Additionally, it should be noted that the current detection device 10 can be connected to a computer terminal via a wireless module. The outer cover 706 can house a battery powering the current detection device 10, the wireless module, and other modules. In practice, several current detection devices 10 can be used to monitor the connectors of the entire current-feeding rail system in real time, enabling rapid response and identification of corresponding fault points for quick repair. Alarm devices can also be installed.
[0036] Furthermore, the insulating outer shell 701 has two detection holes, and the openings of the detection holes are connected to insulating bolts 702; the conductive pin 703 has a hollow structure, and a first insulating layer 712 is provided inside it. A conductive probe 711 is provided inside the first insulating layer 712, and one end of the conductive probe 711 is provided inside the detection hole; the cable cores of the socket cable 5 and the plug cable 6 are respectively electrically connected to the other end of the corresponding conductive probe 711, and a second insulating layer 713 is provided between the conductive probe 711 and the conductive bushing 704.
[0037] The cable cores of the socket cable 5 and the plug cable 6 are respectively connected to one end of the conductive probe 711. The conductive probe 711 is located within the first insulating layer 712 of the conductive pin 703 and is isolated from the conductive bushing 704 by the second insulating layer 713. During testing, the insulating bolt 702 is unscrewed, and the probe of the testing equipment contacts the end of the conductive probe 711 inside the testing hole to measure the electrical signal. The first insulating layer 712 and the second insulating layer 713 isolate the conductive probe 711 from the conductive pin 703 and the conductive bushing 704, allowing the electrical signal of the cable core to be transmitted independently through the conductive probe 711.
[0038] In practice, implementation method 2 can also be adopted. Figure 7 , Figure 8Manual testing can be performed by inserting the probes of a testing device (such as a multimeter) into the testing hole, making contact with the end of the conductive probe 711 located inside the testing hole. The connection status of the socket cable 5 and the plug cable 6 is determined by measuring the electrical signal. For example, by contacting one of the conductive probes 711 and the corresponding current rail with the two probes of the multimeter respectively, the electrical connection between the cable and the current rail can be checked for continuity; by contacting the two conductive probes 711 with the two probes of the multimeter respectively, the electrical connection of the cable plug-in contact can be checked for continuity. This manual testing method can supplement automated testing, forming a secondary confirmation function, and can be used when the current detection device 10 malfunctions, when the overload protection 8 is tripped, or when detailed troubleshooting is required.
[0039] Additionally, it should be noted that in this invention, the insulating shell 701, insulating sleeve 705, first insulating layer 712, second insulating layer 713, socket shell 301, socket cover 302, plug shell 401, and plug cover 402 are all made of insulating materials, such as common insulating materials like polycarbonate, epoxy resin, and ceramics.
