Technical Field

[0001] The utility model relates to the technical field of low-voltage intelligent switch cabinets, in particular to a dual RJ45 interface communication device. Background Art

[0002] With the rapid development of smart grids and smart substations, low-voltage smart switchgear, as an important part of the power system, has a modular design of smart drawer units, which are safe, reliable, and highly versatile. Their applications in projects are gradually increasing. With the widespread demand for intelligent applications, low-voltage drawer cabinet feeder circuits are mostly equipped with data storage and (Mabao) protection devices, which exchange data with the superior monitoring system in real time through the communication interface on the drawer unit to achieve remote monitoring, debugging, control and management, including start, stop, restart and other operations.

[0003] At present, the communication of intelligent drawer units mostly adopts secondary plug-in wiring or USB conversion, which can realize simple communication connection mode, but has too many wiring heads and connection points, cumbersome operation, poor shielding, and easy to cause poor contact and communication interruption. At the same time, it has disadvantages such as low communication rate, so it is not convenient for users to use widely, and there are technical defects and shortcomings.

[0004] Secondly, the communication interface of the intelligent switch cabinet mostly adopts a single interface, but in actual applications, a single interface may have problems such as low communication rate and poor stability, and cannot meet the requirements of high reliability and high-speed data transmission.

[0005] Therefore, there is room for improvement, and the utility model provides a dual RJ45 interface communication device. Utility Model Content

[0006] In view of the shortcomings of the prior art, the utility model aims to provide a dual RJ45 interface communication device, the specific scheme is as follows:

[0007] A dual RJ45 interface communication device, the dual RJ45 interface communication device comprising:

[0008] A movable plug assembly, used for being placed on the movable drawer component;

[0009] The static socket assembly is used to be placed on the frame outlet plate;

[0010] The movable plug assembly includes a movable plug body and a plug device. The movable plug body can be detachably mounted on one side of the movable drawer component. The plug device can be detachably mounted in the movable plug body. The plug device has an RJ45 communication plug module 1 built in.

[0011] The static socket assembly includes a static socket body and an RJ45 straight-through adapter. The static socket body can be detachably mounted on one side of the frame outlet plate. The RJ45 straight-through adapter can be detachably mounted in the static socket body. The RJ45 straight-through adapter is equipped with an RJ45 communication plug module 2 for accessing an external communication cable. The end of the RJ45 straight-through adapter facing away from the RJ45 communication plug module 2 is provided with a plug connection slot for freely plugging and unplugging with the RJ45 communication plug module 1.

[0012] Among them, a retractable guide component is provided between the movable plug body and the static socket body, and the movable plug component switches between a contact state and a separation state with the static socket component through the guide component.

[0013] Thus, through the cooperation of the dynamic plug assembly and the static socket assembly, due to the setting of the RJ45 communication plug module 1 and the RJ45 communication plug module 2, the two assemblies are respectively provided with independent RJ45 interfaces, which can provide two high-speed and stable communication channels at the same time. When the intelligent drawer unit needs to perform communication functions such as data transmission, with the assistance of the guide assembly, when the dynamic plug assembly moves with the movable drawer component to the contact state with the static socket assembly, since the guide assembly has the functions of free extension and correction, the contact stroke can be automatically adjusted during the plug-in process of the RJ45 communication plug module 1 on the dynamic plug assembly and the RJ45 straight-through adapter on the static socket assembly, until the RJ45 communication plug module 1 and the RJ45 straight-through adapter are connected. In addition, the RJ45 communication plug module of the RJ45 straight-through adapter can be connected to an external communication cable.

[0014] Therefore, for example, when one end of the RJ45 communication plug module in the movable drawer component is plugged into the protection device, the entire communication circuit can be connected to ensure real-time transmission and backup of data.

[0015] Further, the plug device includes a telescopic mold box, a pressure block, and a fastening screw;

[0016] The telescopic mold box is clamped on the movable plug body, and an installation slot for accommodating the RJ45 communication plug module 1 is formed inside the telescopic mold box. The pressure block is detachably fixedly connected to the telescopic mold box by fastening screws. The pressure block is in the installation slot, and the pressure block is crimped to the RJ45 communication plug module 1.

[0017] Therefore, the stability of the RJ45 communication plug module in the telescopic mold box can be improved by pressing the block.

[0018] Furthermore, two wire outlet notches are symmetrically provided on the pressing block, and a wire binding rack is embedded in the wire outlet notches. The wire binding rack is used to contact the communication wire in the RJ45 communication plug module.

[0019] In this way, the communication wire can pass through the telescopic mold box under the guidance of the wire binding rack and the gap, which is convenient for cooperation with the subsequent RJ45 straight-through adapter.

[0020] Furthermore, a mounting circular hole is provided on the movable drawer component, and the movable plug body is detachably fixedly connected to the movable drawer component through the mounting circular hole by using a plurality of step screws, and a gap is provided between the step screw and the mounting circular hole.

[0021] Thus, the entire movable plug assembly can be assembled on the movable drawer component, which is convenient for operation.

[0022] Furthermore, a card slot is symmetrically provided on the main body of the static socket, and buckles are provided on both wings of the card slot. A card block cooperating with the buckles is provided on the outer wall of the RJ45 straight-through adapter. The RJ45 straight-through adapter is inserted into the card slot, and the buckles cooperate with each other to achieve locking.

[0023] In this way, the static socket body and the RJ45 straight-through adapter can be snapped into place, making installation easier.

[0024] Further, the guide assembly includes a spring and a guide pin;

[0025] The telescopic mold box is located around the plug device to form at least two cylindrical guide cavities, and the movable plug body is located at the end of the guide cavity to form an undercut limit plate, and a spring is placed in each guide cavity, and the spring abuts against the undercut limit plate;

[0026] Two guide pins are provided and are detachably mounted on the static socket body for matching with different guide cavities.

[0027] Therefore, the guide pin plays a guiding role for the movable plug assembly, and the free expansion and contraction of the spring plays a role in automatically adjusting the contact stroke.

[0028] Furthermore, the frame outlet plate and the static socket body are also provided with mounting circular holes, one end of the guide pin is set as a threaded end, and the threaded end of the guide pin is successively passed through the mounting circular holes on the frame outlet plate and the static socket body and then locked by a nut.

[0029] Therefore, the entire static socket assembly can be assembled on the frame outlet plate through the guide pin, which is easy to operate.

[0030] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0031] (1) The utility model adopts a dynamic plug assembly and a static socket assembly, and based on the design of a dual RJ45 interface, it can provide two high-frequency, high-speed, and stable communication channels at the same time. Compared with the defects of the secondary plug-in wiring method or USB conversion method in the prior art, the utility model only needs to build two components involving the RJ45 interface into the dynamic plug assembly and the static socket assembly, and then with the assistance of a purely mechanical structure, wiring and connection can be achieved. The wiring heads and connection points are reduced, and the RJ45 interface can realize the rapid plugging and unplugging of communication cables, which is simple to operate. Therefore, the utility model ensures the continuous stability of communication, meets the high-speed data transmission rate, and the communication interface is plug-and-play, easy to operate, wide in application, safe and reliable.

[0032] (2) In the RJ45 communication plug module 1, the RJ45 straight-through adapter, and the RJ45 communication plug module 2 of the present invention, high-quality industrial-specific plug devices and optimized structural designs are used inside the plug-in to ensure the stability and reliability of communication; the plug-in design has good versatility and scalability, and can be easily integrated and expanded with other devices or systems.

[0033] (3) Through the setting of the guide assembly, the movable parts of the utility model have automatic extension and correction functions, thereby avoiding collision, jamming and poor contact caused by structural size errors, and ensuring reliable communication.

DETAILED DESCRIPTION

[0043] The present invention will be further described in detail below in conjunction with the embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0044] A dual RJ45 interface communication device adopts a straight-through dual RJ45 interface design and can provide two high-frequency, high-speed and stable communication channels at the same time. The RJ45 interface realizes fast plugging and unplugging of communication cables to solve the defects and shortcomings of the existing technology and meet the high-speed communication requirements of the intelligent switch cabinet.

[0045] like Figure 1 The device includes a movable plug assembly 3 arranged on a movable drawer component 1 and a static socket assembly 6 arranged on a frame outlet board 2.

[0046] It should be noted that in a low-voltage intelligent switch cabinet, the intelligent drawer units are usually arranged vertically in front of the cabinet. According to different needs, multiple layers can be configured. Each intelligent drawer unit can be plugged in and out independently, and each layer of intelligent drawer units is responsible for different power distribution and control tasks. In the intelligent drawer unit, the movable drawer component 1 is usually assembled at the front position of the cabinet, which is convenient for operators to directly plug in and out the intelligent drawer unit from the front panel and perform various operations such as installation, maintenance and replacement; the frame outlet board 2 is generally installed at the rear position, bottom position or side position of the cabinet. In the utility model, in order to facilitate the cooperation with the movable plug assembly 3, the frame outlet board 2 is in the rear position to provide sufficient space and interface, facilitate cable access and fixation, and ensure that the wiring is firm and neat.

[0047] like Figure 2The movable plug assembly 3 is composed of a movable plug body 4 and a plug device 5. The movable plug body 4 is a bearing component and can be detachably installed on one side of the movable drawer component 1. The plug device 5 can be detachably installed in the movable plug body 4, and the movable plug body 4 wraps the plug device 5.

[0048] like Figure 3 , wherein the movable plug body 4 is in the shape of a rectangular shell as a whole, and one end of the movable plug assembly 3 is bent to form a mounting surface. In order to install the entire movable plug assembly 3 on the movable drawer component 1, a mounting circular hole 10 is respectively opened at the four corners of the movable drawer component 1, and a mounting circular hole 10 is also correspondingly opened on the mounting surface. The movable plug body 4 is detachably fixedly connected to the movable drawer component 1 through the mounting circular hole 10 using four step screws 11, and the step screws 11 are locked by nuts 12.

[0049] It should be noted that a gap is provided between the step screw 11 and the mounting circular hole 10 so that the step screw 11 is in a free-floating state, so that the position of the movable drawer component 1 can be adjusted to a certain extent during the subsequent plugging and unplugging process.

[0050] Combination Figure 2 , 3 Secondly, the plug device 5 is composed of a telescopic mold box 51, an RJ45 communication plug module 52, a fastening screw 53 and a pressing block 54. The RJ45 communication plug module 52 is used to connect with the device in the movable drawer component 1 to transmit signals. In order to accommodate the RJ45 communication plug module 52, a symmetrically arranged installation slot 511 is formed inside the telescopic mold box 51. The installation slot 511 is provided with an anti-stuck rib. The RJ45 communication plug module 52 is correspondingly plugged into the installation slot 511, and its plug head protrudes from the outside of the movable plug body 4. Afterwards, the RJ45 communication plug module 52 is fixed in the telescopic mold box 51 by the pressing block 54, and finally the plug device 5 is formed.

[0051] It should be noted that the plug device 5 is integrally mounted in the movable plug body 4. In order to achieve the mounting, the inner wall of the movable plug body 4 is provided with an anti-dropping slot. Correspondingly, retractable clips are provided on the two sides of the retractable mold box 51. The retractable clips are connected with the RJ45 interface in the prior art to achieve a clamping structure. After the retractable mold box 51 is built into the movable plug body 4, the anti-dropping slot and the retractable clip cooperate to make the retractable mold box 51 removable and fixed in the movable plug body 4.

[0052] like Figure 3In order to fix the RJ45 communication plug module 1 52 in the telescopic mold box 51, two outlet notches 541 are symmetrically opened on the pressing block 54, and a screw hole 542 is opened around and in the center respectively, and a protruding tail is provided at the end. After the RJ45 communication plug module 1 52 is correspondingly plugged into the installation slot 511, the pressing block 54 is also placed in the installation slot 511, and the outlet notch 541 leads out the communication wire on the RJ45 communication plug module 1 52 to avoid interference. After that, a fastening screw 53 is correspondingly installed in each screw hole 542. Under the locking cooperation of multiple fastening screws 53 and the telescopic mold box 51, the pressing block 54 realizes a detachable fixed connection. Correspondingly, five circular blind holes can be opened on the surface of the telescopic mold box 51, so that the fastening screws 53 are placed in the circular blind holes after passing through the pressing block 54, avoiding damage to the telescopic mold box 51.

[0053] More specifically, Figure 3 A wire tie frame 543 with arc-shaped surfaces at both ends is embedded in the wire outlet notch 541. The wire tie frame 543 is used to contact the communication wires in the RJ45 communication plug module 1 52 to limit the two communication wires and improve stability. After the two communication wires are led out from the pressing block 54, they can be tied with the protruding tail of the pressing block 54 using a cable tie to prevent them from loosening.

[0054] It should be noted that one end of the RJ45 communication plug module 52 in the movable drawer unit 1 is plugged with the protection device (or detection device), and the other end is deeply connected to the plug device 5 in the movable plug assembly 3, and its communication wire is reserved with a certain arc and can be freely extended. It should be noted that the protection device is a data storage and (Mabao) protection device, and in the present utility model, there is no specific limitation, and the RJ45 communication plug module 52 can also be plugged with other devices in the intelligent drawer unit.

[0055] Combination Figure 3 and Figure 4 The static socket assembly 6 includes a static socket body 61 and an RJ45 straight-through adapter 62 . The static socket body 61 is a bearing component and can be detachably installed on one side of the frame outlet board 2 . The RJ45 straight-through adapter 62 can be detachably installed in the static socket body 61 .

[0056] Among them, the RJ45 straight-through adapter 62 has a built-in RJ45 communication plug module 2 621, and the RJ45 communication plug module 2 621 is used to connect to the external communication cable 63. It should be noted that the external communication cable 63 is the communication output part, and the use of the RJ45 communication plug can achieve fast connection to form a high-speed communication network. In addition, the end of the RJ45 straight-through adapter 62 away from the RJ45 communication plug module 2 621 is provided with a plug connection slot 622 for free plugging and unplugging with the RJ45 communication plug module 1 52.

[0057] Secondly, in order to realize the detachable installation of the RJ45 straight-through adapter 62 in the static socket body 61, the static socket body 61 is symmetrically provided with a card slot 611, and the two wings of the card slot 611 are provided with buckles. The outer wall of the RJ45 straight-through adapter 62 is provided with a card block that cooperates with the buckle. The RJ45 straight-through adapter 62 is inserted into the card slot 611, and the buckle and the card block cooperate to achieve locking, thereby realizing detachable installation.

[0058] It should be noted that the static socket assembly 6 connected to the external communication cable 63 can achieve communication connection between the static socket assembly 6 and the dynamic plug assembly 3 through the built-in RJ45 straight-through adapter 62 .

[0059] Combination Figure 2 and Figure 5 Under normal circumstances, when the movable drawer component 1 and the outlet function board are in a separated / isolated state, the static socket assembly 6 and the dynamic plug assembly 3 are also in a separated state, the RJ45 communication plug module 1 52 and the RJ45 straight-through adapter 62 are separated, and the RJ45 communication plug module 1 52 and the RJ45 straight-through adapter 62 are equivalent to a primary plug-in at this time, and the RJ45 communication plug module 2 621 and the external communication cable 63 are not connected, and the RJ45 communication plug module 2 621 and the external communication cable 63 are equivalent to a secondary plug-in at this time.

[0060] In this way, when a communication channel needs to be established in the intelligent drawer unit, the movable plug assembly 3 needs to be displaced and combined with 2 and Figure 6 , that is, the movable drawer component 1 is pushed from the separation position to the test position, and the movable drawer component 1 is pushed so that the movable plug assembly 3 and the static socket assembly 6 are in contact. At this time, the RJ45 communication plug module 1 52 and the RJ45 straight-through adapter 62 are still separated, and the RJ45 communication plug module 2 621 and the external communication cable 63 are connected, and the communication circuit is connected. At this time, the movable drawer component 1 can be debugged.

[0061] After debugging is completed, the movable plug assembly 3 continues to move and combines Figure 2 and Figure 7 , the movable drawer component 1 will be pushed from the test position to the connection position. At this time, the RJ45 communication plug module 52 and the RJ45 straight-through adapter 62 will also be connected, so that the primary plug-in and the secondary plug-in inside the intelligent drawer unit are connected, and the entire communication circuit is connected. At this time, the dual RJ45 interface communication device of the utility model is in normal working state.

[0062] It should be noted that, during the displacement of the movable plug assembly 3, in order to avoid collision, jamming and poor contact due to structural dimensional errors, a retractable guide assembly 7 is provided between the movable plug body 4 and the static socket body 61, and the movable plug assembly 3 is switched between the contact state and the separation state with the static socket assembly 6 through the guide assembly 7.

[0063] Specifically, if Figure 6 The guide assembly 7 has automatic telescopic and guiding functions, and specifically includes a spring 8 and a guide pin 9. The spring 8 is used to achieve automatic telescopic movement, and the guide pin 9 plays a guiding function.

[0064] Combination Figure 2 and Figure 3 The telescopic mold box 51 is located around the plug device 5 and forms four cylindrical guide cavities 512. One end of the guide cavity 512 is open and the other end is closed. A spring 8 is placed in each guide cavity 512, and the spring 8 can freely expand and contract in the guide cavity 512. The plug body is located at the end of the guide cavity 512 to form an inverted limit plate 41. Figure 6 It can be seen that the height of the movable plug body 4 is slightly greater than the height of the telescopic mold box 51, so that there is a certain distance between the inverted limit plate 41 and one end of the guide cavity 512. When installing the spring 8, the spring 8 is inserted into the guide cavity 512, and the spring 8 abuts against the inverted limit plate 41, and is locked in the guide cavity 512 by the inverted limit plate 41.

[0065] There are two guide pins 9 for matching with different guide cavities 512. One end of the guide pin 9 is set as a threaded end, and the other end is set with a rounded corner. In order to install the guide pin 9, the frame outlet plate 2 and the static socket body 61 are also provided with installation circular holes 10. The threaded ends of the guide pins 9 are successively passed through the installation circular holes 10 on the frame outlet plate 2 and the static socket body 61 and are locked by nuts 12. Therefore, the utility model only needs to set the guide pins 9 to simultaneously complete the assembly of the static socket assembly 6 and the free correction of the movable plug assembly 3.

[0066] In this way, when the movable plug assembly 3 moves to contact with the static socket assembly 6 and then cooperates, the movable plug assembly 3 is freely guided by the guide pin 9, and as the guide pin 9 extends into the guide cavity 512, the spring 8 is compressed until the movable plug assembly 3 and the static socket assembly 6 are in contact. Afterwards, when the RJ45 communication plug module 1 52 is plugged into the RJ45 straight-through adapter 62 in the static socket assembly 6, the spring 8 will continue to be compressed, and under the action of the guide pin 9, until the RJ45 communication plug module 1 52 is inserted into the RJ45 straight-through adapter 62, the pressure of the spring 8 is relatively reduced.

[0067] Since the spring 8 can freely expand and contract after being stressed, the contact formation of the movable plug assembly 3 can be automatically adjusted to ensure reliable communication. While ensuring the contact reliability, the service life of the spring 8 is increased.

[0068] In summary, through the cooperation of the dynamic plug assembly 3 and the static socket assembly 6, the intelligent drawer unit can be quickly plugged in and out to ensure the stability of communication with each other, making maintenance faster. At the same time, the communication plug-in of this structural solution meets the three-position requirements of the drawer.

[0069] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
