Description

Technical Field

[0001] This invention relates to a network port connection structure, specifically a network port connection structure for a high-protection plug-in panel, belonging to the technical field of control and protection devices. Background Technology

[0002] Currently, the network port connection structure of the control and protection plug box in the power system has significant design shortcomings: the communication (RJ45) socket module is directly soldered to the back of the board and embedded in the panel opening, relying only on the connection cover for protection. This network port connection structure has both mechanical fixation and environmental protection deficiencies. In addition, the network port base is installed with cross countersunk screws, which are prone to loosening and failure under transportation vibration conditions.

[0003] As the application scenarios of control and protection devices continue to expand, the vibration protection standards for network port structures are also being upgraded. Existing structures face two major pain points: first, vibration and frequent plugging / unplugging can easily cause poor contact at the socket solder joints, leading to communication interruptions; second, the gap between the RJ45 plug and the panel perforation poses a potential conductive contact risk, severely weakening electromagnetic shielding effectiveness. Furthermore, network port plugs need to meet both dustproof sealing and anti-detachment requirements. Therefore, developing a high-protection-level integrated network port structure has key engineering value for improving the environmental adaptability and operational stability of control and protection modules. Summary of the Invention

[0004] The purpose of this invention is to provide a high-protection socket panel network port connection structure that not only meets the dual requirements of dustproof sealing and anti-detachment, but also avoids poor contact at the socket solder joints due to vibration, impact, or frequent plugging and unplugging, and avoids weakening the electromagnetic shielding effectiveness. This solves the technical drawbacks of the existing control and protection device panel network port structure, which cannot meet the requirements of high protection and operational stability.

[0005] To achieve the above objectives, the technical solution of the present invention is: a network port connection structure for a high-protection plug box panel, the innovation of which lies in: including a network port fixing assembly and a protective elastic plug movably disposed on the communication socket.

The communication socket passes through the clearance through hole of the button board and is connected to the communication socket connection board by soldering.

[0007] In the above technical solution, a hexagonal spacer post is provided between the communication socket connection board and the keypad board for adjusting the distance between them. The pan head screw of the pan head screw assembly passes through the hexagonal spacer post, so that the communication socket connection board and the keypad board form a detachable connection structure.

[0008] In the above technical solution, the network port base is provided with a slanted guide square hole, and the communication socket on the communication socket connection board passes through the guide square hole, so that the outer periphery of the communication socket fits against the inner wall of the square hole of the network port base.

[0009] In the above technical solution, the guide square hole of the network port base has an opening with a 2°~5° angle towards the insertion direction of the communication socket, so that the side wall of the guide square hole and the communication socket form a sealed connection, thereby improving the structural rigidity and electromagnetic shielding effectiveness.

[0010] In the above technical solution, the mesh base and the insertion box panel are connected by countersunk screws. The front of the insertion box panel and the end face of the countersunk screws are covered with PET film to fix and limit the countersunk screws to prevent rotation and / or loosening.

[0011] In the above technical solution, two slotted holes are provided on the insert box panel, and two countersunk screws pass through the corresponding slotted holes and are threadedly connected to the mesh base attached to the back of the insert box panel to form a stable and fastened structure with two points and one surface.

[0012] In the above technical solution, the end face of the countersunk screw is parallel to the front face of the insert panel. The adhesive backing of the PET film is bonded to the front face of the insert panel and the end face of the countersunk screw. The thickness of the adhesive backing of the PET film is 0.15mm~0.25mm, which is used to offset the height difference between the countersunk screw and the front face of the insert panel, so that the insert panel, the PET film and the countersunk screw are tightly bonded, forming an anti-loosening and sealing structure.

[0013] In the above technical solution, the tail of the protective elastic plug fits into the groove of the mesh base, and at the same time, a sealed connection is formed between the protective elastic plug and the side wall of the opening of the insertion box panel.

[0014] In the above technical solution, the tail of the protective elastic plug is provided with an I-shaped connector, and the I-shaped connector is snapped into the corresponding connection hole on the mesh base to prevent the protective elastic plug from falling off or falling off the mesh base after being pulled out.

[0015] In the above technical solution, the mesh base is provided with two stepped holes, and the I-shaped connector at the tail of the protective elastic plug is engaged in the corresponding stepped hole, so as to adjust and ensure the suspension length of the protective elastic plug under the working conditions of insert box panels of different thicknesses.

[0016] In the above technical solution, blind hole rivet studs are pressed onto the plug box panel, and the keypad is fixed to the blind hole rivet studs by screws, so as to achieve stable fixing of the keypad and communication socket connection board at different heights from the plug box panel.

[0017] In the above technical solution, the network port base includes an integral base positioning plate. The base positioning plate has a groove and a guide square hole. The guide square hole is surrounded by a limiting barrier with a clearance notch. The groove is adjacent to the clearance notch of the limiting barrier. A portion of the communication socket is embedded in the guide square hole and forms a sealed connection with the limiting barrier.

[0018] In the above technical solution, the protective elastic plug includes a protective cover plate and a socket protective sleeve that are integrated together. The protective cover plate is located at the opening of the plug box panel, and the socket protective sleeve is located on the back of the protective cover plate. After passing through the opening of the plug box panel, it is inserted into the socket hole of the communication socket.

[0019] In the above technical solution, the back of the protective cover is provided with a flexible elastic cord to prevent loss, and the tail of the flexible elastic cord is provided with an I-shaped connector. The flexible elastic cord is disposed in the groove of the mesh base, and the I-shaped connector is snapped into the corresponding connection hole in the groove.

[0020] In the above technical solution, the front side of the protective cover is provided with a flexible plug-in connector.

[0021] In the above technical solution, the mesh base is made by a one-time metal powder molding process, and the protective elastic plug is a silicone rubber plug or a polyurethane elastic plug.

[0022] The positive effects of this invention are: by adopting the network port connection structure of the high-protection plug box panel of this invention, since this invention includes a network port fixing assembly and a protective elastic plug movably disposed on the communication socket, The network port mounting assembly includes a network port base mounted on the back of the sub-panel panel. The network port base is detachably connected to the sub-panel panel. The communication socket is fixedly connected to a PCB board assembly located on the back of the sub-panel panel, and the communication socket and the network port base are connected in a plug-in manner. The protective elastic plug passes through the opening in the socket panel and is inserted into the socket of the communication socket, forming a movable and sealed connection between the protective elastic plug and the communication socket. At the same time, the network port base forms an isolation barrier between itself and the external environment, improving the overall protection level. The advantages of this network port connection structure design of the present invention are: (1) The network port base and the communication socket are in close contact and fit together. The protective elastic plug is inserted into the inner hole of the communication socket and the opening of the plug box panel, forming a movable sealing connection structure, so that the network port base forms an isolation barrier with the external environment, and achieves the isolation of internal devices from the outside world to achieve a high protection effect of IP65.

[0023] (2) The mesh base structure described in this invention is simple, has low processing cost, and has good overall strength and precision, making it suitable for mass production.

[0024] This invention ensures a rigid connection between the network port base, the communication socket, and the socket panel, preventing loosening or failure under transportation vibration. It also prevents poor contact at the socket's solder joints, thus avoiding communication interruptions, under vibration, impact, and frequent plugging / unplugging. Furthermore, the sealing structure between the communication socket and the socket panel overcomes the potential for conductive contact due to gaps in existing technologies, preventing a weakening of electromagnetic shielding effectiveness. In addition, the protective elastic plug of this invention addresses both dustproof sealing and anti-detachment requirements.

[0025] In summary, this invention not only meets the dual requirements of dustproof sealing and anti-detachment, but also prevents poor contact at the socket solder joints due to vibration, impact, or frequent plugging and unplugging, and avoids weakening of electromagnetic shielding effectiveness. It solves the technical drawbacks of the existing control and protection device panel network port structure, which cannot meet the requirements of high protection and operational stability.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0029] like Figure 1 , 2 As shown in Figures 3, 4, 5, 6, 7, and 8, a network port connection structure for a high-protection plug box panel includes a network port fixing assembly and a protective elastic plug 1 movably disposed on the communication socket 3 (RJ45 socket). The network port mounting assembly includes a network port base 2 mounted on the back of the sub-panel panel 5. The network port base 2 is detachably connected to the sub-panel panel 5. The communication socket 3 is fixedly connected to a PCB board assembly on the back of the sub-panel panel 5, and the communication socket 3 and the network port base 2 are connected in a plug-in manner. The protective elastic plug 1 passes through the opening in the plug box panel 5 and is inserted into the socket of the communication socket 3, so that the protective elastic plug 1 and the communication socket 3 form a movable sealed connection structure. At the same time, the network port base 2 forms an isolation barrier with the external environment, improving the overall protection level.

[0030] Furthermore, such as Figure 3As shown, in order to ensure that the communication socket is fixedly connected to the corresponding connection board without interfering with other boards, the PCB board assembly includes a communication socket connection board 4 and a button board 8. The communication socket connection board 4 and the button board 8 are detachably connected by a pan head screw assembly 11, and the button board 8 is detachably connected to the plug box panel 5. The communication socket 3 passes through the clearance through hole of the button board 8 and is connected to the communication socket connection board 4 by soldering.

[0031] Furthermore, such as Figure 3 As shown, in order to simultaneously achieve the relative position between the communication socket and the board, the communication socket connection board, after being soldered with the communication socket, uses spacers to control its relative position and is fixed to the keypad board. A hexagonal spacer 13 is provided between the communication socket connection board 4 and the keypad board 8 to adjust the distance between them. The pan head screws of the pan head screw assembly 11 pass through the hexagonal spacer 13, forming a detachable connection structure between the communication socket connection board 4 and the keypad board 8. That is, the present invention controls the relative position of the communication socket connection board 4 and the keypad board 8 by controlling the length of the hexagonal spacer 13, thus adjusting the appropriate distance.

[0032] Furthermore, such as Figure 3 , 4 As shown in Figure 5, in order to enable the network port base and the communication socket to be quickly positioned and guided for connection, the network port base 2 is provided with a slanted guide square hole. The communication socket 3 on the communication socket connection board 4 passes through the guide square hole, and the outer periphery of the communication socket 3 is in contact with the inner wall of the square hole of the network port base 2.

[0033] Furthermore, such as Figure 7 As shown, in order to make the guide square hole sidewall of the network port base form a tight contact and fit with the communication socket, the opening of the guide square hole of the network port base 2 is provided with an angle of 2°~5° towards the insertion direction of the communication socket 3, so that the guide square hole sidewall and the communication socket 3 form a sealed connection, thereby improving the structural rigidity and electromagnetic shielding effectiveness.

[0034] Furthermore, the mesh base 2 of the present invention is preferably designed with a 2° angled opening.

[0035] Furthermore, such as Figure 2As shown, in order to facilitate the detachable connection between the mesh port base and the insert panel, and to fix and restrict the countersunk screws from rotating or loosening, ensuring the tightness of the connection between the two and preventing loosening, and with the synergistic effect of the PET film, to seal the openings of the insert panel, forming a complete isolation barrier, so that the overall protection level reaches IP65, the mesh port base 2 and the insert panel 5 are connected by countersunk screws 9. The front of the insert panel 5 and the end face of the countersunk screws are covered with PET film 7, which is used to fix and restrict the countersunk screws to prevent rotation and / or loosening.

[0036] Furthermore, such as Figure 2 As shown, in order to ensure a stable fit and fixation structure between the mesh port base and the insertion box panel, two slotted holes are provided on the insertion box panel 5. Two countersunk screws 9 pass through the corresponding slotted holes and are threadedly connected to the mesh port base 2 attached to the back of the insertion box panel 5, forming a stable fit and fixation structure with two points and one surface.

[0037] Furthermore, such as Figure 2 As shown, in order to compensate for the height difference between the countersunk screw and the insert panel, and to ensure that the countersunk screw can form an anti-loosening and sealing structure with the insert panel and the film, the end face of the countersunk screw 9 is parallel to the front face of the insert panel 5. The adhesive backing of the PET film 7 is bonded to the front face of the insert panel 5 and the end face of the countersunk screw 9, and the thickness of the adhesive backing of the PET film 7 is 0.15mm~0.25mm. That is, this thick adhesive backing of the present invention can offset the height difference between the countersunk screw and the front face of the insert panel 5, so that the insert panel 5, the PET film 7 and the countersunk screw 9 form a tight bond, forming an anti-loosening and sealing structure and mutually restraining and fixing state, avoiding the risk of screw loosening under harsh transportation conditions. At the same time, the film isolates the gaps in the screw hole, improving the protection level.

[0038] Furthermore, such as Figure 4 As shown, in order to ensure the sealing between the protective elastic plug and the insert panel, and to position the protective elastic plug, the tail of the protective elastic plug 1 is fitted into the groove of the mesh base 2, and a sealed connection is formed between the protective elastic plug 1 and the side wall of the opening of the insert panel 5.

[0039] Furthermore, such as Figure 4 As shown, in order to prevent the protective elastic plug from falling off after being pulled out and thus avoid loss, the tail of the protective elastic plug 1 is provided with an I-shaped connector 11, and the I-shaped connector 11 is snapped into the corresponding connection hole on the mesh base 2, so as to prevent the protective elastic plug 1 from falling off or falling off the mesh base 2 after being pulled out.

[0040] Furthermore, the mesh base 2 is provided with two stepped holes, and the I-shaped connector at the tail of the protective elastic plug 1 is engaged in the corresponding stepped hole. This satisfies the need to adjust and ensure the suspension length of the protective elastic plug 1, i.e., the suspension length of the flexible elastic 14, under different thicknesses of panel inserts. The present invention provides stepped holes at two different locations on the mesh base. This design aims to allow the protective elastic plug to be fitted into different stepped holes, adjusting its suspension length to meet the installation requirements of both thick aluminum panels and thin steel panels.

[0041] Furthermore, such as Figure 3 As shown, in order to achieve the requirement of stable fixation at different heights between the keypad and communication socket connection board and the plug box panel, and to simultaneously meet the requirements of convenient plug-in of the communication socket and smooth keypad function, blind hole rivet studs 12 are pressed onto the plug box panel 5. The keypad 8 is fixed to the blind hole rivet studs 12 by screws, so as to achieve stable fixation of the keypad 8 and communication socket connection board 4 at different heights with the plug box panel 5.

[0042] Furthermore, such as Figure 6 , 7 As shown, in order to enable the network port base of the present invention to take into account multiple functions and functions and have a reasonable structure, the network port base 2 includes a base positioning plate 21 that is integrated with the base. The base positioning plate 21 has a groove 22 and a guide square hole, and the periphery of the guide square hole is provided with a limiting barrier 23 with a clearance notch. The groove 22 is adjacent to the clearance notch of the limiting barrier 23. A portion of the communication socket 3 is embedded in the guide square hole and forms a sealed connection with the limiting barrier 23.

[0043] Furthermore, such as Figure 8 As shown, in order to meet the dual requirements of dustproof sealing and anti-detachment of the protective elastic plug, the protective elastic plug 1 includes a protective cover plate 12 and a socket protective sleeve 13 that are integrated together. The protective cover plate 12 is located at the opening of the plug box panel 5, and the socket protective sleeve 13 is located on the back of the protective cover plate 12, and it passes through the opening of the plug box panel 5 and is inserted into the socket hole of the communication socket 3.

[0044] Furthermore, such as Figure 8 As shown, in order to prevent loss after the protective elastic plug is removed, the back of the protective cover plate 12 is provided with a flexible elastic cord 14 to prevent loss, and the tail of the flexible elastic cord 14 is provided with an I-shaped connector 11. The flexible elastic cord 14 is disposed in the groove 22 of the mesh base 2, and the I-shaped connector 11 is snapped into the corresponding connection hole in the groove 22.

[0045] Furthermore, such as Figure 8 As shown, in order to facilitate the insertion and removal of the protective cover, the front of the protective cover 12 is provided with a flexible plug-in connector 15.

[0046] Furthermore, the network port base 2 of this invention is manufactured using a one-time metal powder molding process, resulting in a lightweight structure, material-saving design, and ease of mass production, significantly enhancing the environmental adaptability and operational stability of the control and protection device. The network port base structure of this invention is adapted to the plug-in / plug-out contact of communication sockets, the threaded assembly of screws fixing the plug box panel, and the connection requirements of the protective elastic plug tail, while simultaneously meeting the requirements of material saving, robustness, and modular mass production.

[0047] Furthermore, in order to provide a high level of protection for the opening of the insert panel and form a natural isolation barrier, the protective elastic plug 1 is a silicone rubber plug or a polyurethane elastic plug.

[0048] The advantages of this invention are: (1) The high protection plug box panel of the present invention has a network port connection structure in which the RJ45 square hole on the network port base is provided with a 2° opening facing the insertion direction, so that the side wall of the square hole of the network port base and the communication (RJ45) socket are in close contact and fit together. The bottom surface of the network port base is precisely fitted with the back of the plug box panel and is designed to prevent loosening. The silicone rubber plug is inserted into the inner hole of the RJ45 socket and the opening of the plug box panel, and is connected on the front of the plug box panel to form a complete barrier, thereby achieving the isolation between the internal components and the outside world and achieving the high protection effect of IP65.

[0049] (2) The present invention has a specially designed mesh base structure, which is simple in structure, saves materials, has good processability, and adopts a complex structure such as mesh slope formed by metal powder in one step to realize multiple functions. It has low processing cost, is suitable for mass production, and has good overall strength and precision.

[0050] (3) The present invention has two specially designed salad holes on the mesh base, combined with the length of the silicone rubber plug tail, which can simultaneously meet the working conditions of the old thick aluminum panel and the new thin steel panel.

[0051] (4) The PET film with adhesive backing described in this invention is pasted on the outer surface of the insert box panel, which not only improves the aesthetics of the panel, but also cleverly improves the anti-loosening ability of the fastening screws of the mesh base.

[0052] Therefore, this invention aims to solve the problems of insufficient mechanical fixation of network ports in existing control and protection boxes, low protection levels, poor electromagnetic shielding, and easy detachment of silicone covers. It ensures a rigid connection between the network port base, the communication socket, and the box panel, preventing loosening and failure under transportation vibration conditions. It also ensures that poor contact at the socket solder joints, leading to communication interruptions, will not occur under vibration, impact, or frequent plugging and unplugging. Furthermore, the sealing structure between the communication socket and the box panel overcomes the potential for conductive contact due to gaps in existing technologies, preventing a weakening of electromagnetic shielding effectiveness. In addition, the protective elastic plug of this invention addresses both dustproof sealing and anti-detachment requirements.

[0053] In summary, this invention achieves an IP65 protection rating through multi-level sealing protection and reinforced fastening design, improving electromagnetic shielding effectiveness and vibration resistance and anti-loosening capabilities, and solving the technical shortcomings of the existing control and protection device panel network port structure that cannot meet the requirements of high protection and operational stability.
