Description

Technical Field

[0001] This application relates to the field of connector technology, and in particular to an RJ strip connector structure. Background Technology

[0002] In the field of electronic information and network communication, RJ connectors and printed circuit boards (PCBs) are the core basic components of various network terminals and communication equipment. Among them, RJ series RJ connectors are interface components used to establish physical connections for wired networks. By plugging and unplugging with network cables, external network signals are introduced into the device. The PCB integrates various electronic components such as resistors, capacitors, chips, and sensors. Through the pre-set circuit traces on the PCB, the transmission of electrical signals and power distribution between the components are realized.

[0003] When the RJ connector is assembled with the PCB board, the RJ connector is fixed to the surface of the PCB board through its own mounting structure. The signal terminals inside the RJ connector form an electrical connection with the circuit pads on the PCB board, thereby stably transmitting the network signal input from the external network cable to the PCB board. At the same time, it receives and processes the signal and feeds it back to the external network, ultimately realizing the functions of network communication and data exchange of the device.

[0004] In related technologies, for electronic devices requiring multiple network interfaces, such as multi-port routers, the industry commonly uses multiple independent RJ connectors side-by-side spliced ​​onto a PCB board. The diameter of the mounting pins of existing RJ connectors is showing a significant increasing trend, and the increased diameter is larger than the diameter of the pre-set mounting holes on the PCB board. Because the diameter of the mounting pins is larger than the mounting holes on the PCB board, an axial force must be applied during assembly to forcefully press the mounting pins into the corresponding mounting holes on the PCB board. After the protruding part of the mounting pin has completely passed through the mounting hole, the protruding part will form a mechanical limit with the back of the PCB board. Without applying additional reverse force, the connector and the PCB board cannot be easily separated. At the same time, existing connectors use a traditional surface mount method to complete the final positioning with the PCB board. The signal terminals inside the connector have a plug-in assembly structure. During the production process, each terminal needs to be inserted into the pre-set slot of the connector's plastic housing one by one, and each terminal needs to be equipped with a pair of grounding solder pins to ensure the purity and stability of signal transmission in order to form a complete signal transmission channel.

[0005] However, during the assembly process, when external force is applied to the contact area between the mounting feet and the PCB board, instantaneous impact vibration will be generated. This impact vibration will be quickly transmitted through the PCB board structure to the vibration-sensitive components that have been assembled or are to be assembled on the PCB board. The internal structure of such components has low tolerance to vibration impact, and vibration transmission can easily lead to physical damage, ultimately causing the electronic equipment to malfunction after assembly and reducing the product assembly yield. Utility Model Content

[0006] To address the aforementioned issues, this application provides an RJ strip connector structure.

[0007] The RJ strip connector structure provided in this application adopts the following technical solution: it includes a connector body, the connector body is provided with at least one mounting foot, the mounting foot is matched with the diameter of the hole in the PCB board, the mounting foot is inserted into the hole in the PCB board, the bottom surface of the mounting foot is provided with a groove, the groove is connected to the gap formed between the side wall of the mounting foot and the hole wall of the PCB board, after the mounting foot is inserted into the hole in the PCB board, the gap formed between the side wall of the mounting foot and the hole wall of the PCB board is filled by injecting filler into the groove, so that the side wall of the mounting foot expands outward and forms an interference fit with the hole in the PCB board.

[0008] By adopting the above technical solution, in the assembly stage of the connector body and the PCB board, firstly, because the mounting pins of the connector body are pre-matched with the hole diameters of the PCB board, the insertion process of the mounting pins into the PCB board hole only requires a small auxiliary thrust. This reduces the instantaneous impact vibration generated at the contact point between the mounting pins and the PCB board from the initial assembly action. After the mounting pins are fully inserted into the PCB board hole, filler is injected into the groove on the bottom surface of the mounting pins. The filler flows along the groove and fills the gap formed between the side wall of the mounting pin and the PCB board hole. As the filler continues to be injected and solidified, it generates a uniform lateral thrust on the side wall of the mounting pin, pushing the side wall of the mounting pin to slowly expand outward, ultimately forming an interference fit between the mounting pin and the PCB board hole. The entire outward expansion process of the filler is a flexible force transmission, which reduces the vibration impact on vibration-sensitive components and improves the assembly yield.

[0009] Preferably, the groove extends along the length of the bottom surface of the mounting foot, and the groove is a through groove that penetrates the side wall of the mounting foot.

[0010] By adopting the above technical solution, when the mounting pin of the connector body is inserted into the PCB hole, the groove extends along the length of the mounting pin's bottom surface, and its coverage area can match the main area of ​​the mounting pin's bottom surface. At the same time, the groove is a through groove that penetrates the side wall of the mounting pin. Through the opening in the side wall of the mounting pin, it directly connects with the gap formed between the side wall of the mounting pin and the PCB hole. The internal space of the groove and the gap formed between the side wall of the mounting pin and the PCB hole form a channel through the through part of the side wall. At this time, when filler is injected into the groove, the filler first spreads along the length of the groove on the bottom surface of the mounting pin. Then, because the groove penetrates the side wall of the mounting pin, the diffused filler can flow smoothly through the through opening in the side wall to the gap between the side wall of the mounting pin and the PCB hole, forming a complete flow path from the groove to the through opening in the side wall, and then to the gap between the side wall of the mounting pin and the PCB hole. This connection method allows the filler to be evenly distributed along the gap between the side wall of the mounting pin and the PCB hole. When the filler solidifies, it can push the side wall of the mounting pin to expand evenly, ensuring that the mounting pin and the PCB hole form a stable interference fit.

[0011] Preferably, the connector body includes multiple connector housings, which are integrally formed into a row of housings.

[0012] By adopting the above technical solution, since the multiple connector shells of the connector body are processed into a row of shells by integral molding, when multiple interface configurations need to be implemented on the PCB board, the entire row of shells can be operated directly. Through one positioning and one insertion action, the mounting structure corresponding to all connector shells in the row of shells can be synchronously adapted to the preset mounting area on the PCB board, reducing the number of times multiple independent RJ connectors need to be spliced ​​together and reducing the complexity of assembly operations.

[0013] Preferably, each end of the connecting housing is provided with a pair of grounding solder feet, and multiple connector housings share a pair of grounding solder feet.

[0014] By adopting the above technical solution, traditional independent connector housings require a separate grounding solder pad for each connector housing. Since the row housing is integrally formed from multiple connector housings, a pair of grounding solder pads can be set at both ends of the row housing to meet the grounding requirements of all connector housings sharing the row housing. This reduces the total number of grounding solder pads, simplifies the overall structure of the row housing, reduces the cost of metal materials and processing complexity, and reduces the number of steps in assembling the grounding solder pads, thus improving assembly efficiency in multi-interface scenarios.

[0015] Preferably, the grounding solder joint includes a plug portion, the row housing is provided with a plug groove, the plug portion is plugged into the plug groove, the plug portion and the plug groove are interference fit, and the thickness of the plug portion is greater than the thickness of the plug portion corresponding to a conventional single connector.

[0016] By adopting the above technical solution, the plug and the socket are interference-fitted, which has a basic connection and tightness. The thickness of the plug is greater than that of the plug corresponding to a traditional single connector. The increase in thickness directly expands the contact area between the plug and the socket. The stability of the interference fit depends on the friction and engagement force generated by the contact between the plug and the socket. The larger the contact area, the greater the friction under a unit external force, and the more difficult it is for the plug to come loose from the socket. The thicker plug has higher structural strength and stronger resistance to deformation. During the process of inserting it into the socket during assembly, or when subjected to external forces such as vibration and impact during long-term use, it is not easy to have deformation problems such as bending or breakage, and can always maintain the interference fit with the socket.

[0017] Preferably, the grounding weld foot further includes a grounding part that protrudes outward from the row of housings, and the surface flatness deviation of the grounding part is less than 0.1 mm.

[0018] By adopting the above technical solution, when the connector body is assembled with the PCB board, the protruding grounding part can preferentially form physical contact with the grounding pads preset on the PCB board, providing basic contact conditions for the conduction of grounding current. The surface flatness deviation of the grounding part is less than 0.1mm, reducing the situation of contact breakpoints or local suspension caused by uneven grounding part surface. It can make the grounding part surface uniformly fit the PCB board grounding pads. This fit can effectively reduce contact resistance and ensure that the grounding current is conducted quickly and stably.

[0019] Preferably, the connector body further includes multiple terminal structures, each of which corresponds to a plurality of connector housings, and the multiple terminal structures are embedded in the connector housings.

[0020] By adopting the above technical solution, the one-to-one correspondence design of multiple terminal structures and multiple connector housings can match the preset installation slots of each connector housing in the row housing, ensuring that after each terminal structure is embedded in the corresponding connector housing, the position of each terminal structure is consistent with the overall assembly requirements of the row housing. At the same time, the terminal structure is embedded in the connector housing, so that the terminal structure and the corresponding connector housing are tightly combined. When the row housing is synchronously adapted to the PCB board through one action, the terminal structure in each connector housing can also be synchronously adapted to the circuit pads on the PCB board.

[0021] Preferably, the connector body is mounted on the PCB board using surface mount technology.

[0022] By adopting the above technical solutions, surface mount technology can control the mounting position of the connector body on the PCB board, reduce installation deviations, and ensure that the interface position of the connector body is highly matched with the preset circuit layout of the PCB board and the adaptation path of external plug-in components. At the same time, surface mount technology can realize the synchronous mounting and soldering of the connector body and other electronic components on the PCB board, reducing the need to set up a separate mounting station for the connector body and shortening the total assembly time. Especially in mass production scenarios, it helps to reduce the assembly cost per unit connector body and improve production efficiency.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. During the assembly stage of the connector body and the PCB board, since the mounting pins and the hole diameters of the PCB board are pre-matched, only a small auxiliary pushing force is needed to insert the mounting pins into the PCB board holes. This reduces the instantaneous impact vibration acting on the contact area between the mounting pins and the PCB board from the initial assembly action. After the mounting pins are fully inserted, the filler injected into the groove will flow along the groove and fill the gap between the side wall of the mounting pin and the hole of the PCB board. As the filler continues to be injected and solidified, it will generate a uniform lateral thrust on the side wall of the mounting pin, pushing the side wall of the mounting pin to slowly expand outward. The entire expansion process is a flexible force transmission, which can reduce the vibration impact on vibration-sensitive components on the PCB board, thereby improving the assembly yield of the product. 2. Multiple connector housings are manufactured in one piece to form a row of housings. When multiple interface configurations need to be implemented on the PCB board, the entire row of housings can be operated directly. Through one positioning and one insertion action, the mounting structure corresponding to all connector housings in the row of housings can be synchronously adapted to the preset mounting area on the PCB board, thereby reducing the number of times multiple independent RJ connectors need to be spliced ​​together and reducing the complexity of assembly operations. 3. Since the row housing is integrally formed from multiple connector housings, only one pair of grounding solder feet is set at both ends of the row housing to meet the grounding requirements of all connector housings sharing the row housing. This not only reduces the total number of grounding solder feet and simplifies the overall structure of the row housing, but also reduces the cost of metal materials and processing complexity. Furthermore, it reduces the number of steps in assembling the grounding solder feet and improves the assembly efficiency in multi-interface scenarios. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] This application discloses an RJ strip connector structure. (Refer to...) Figure 1 The connector includes a connector body 1, wherein mounting feet 12 are disposed on the connector body 1. In this embodiment, two mounting feet 12 are provided and disposed at both ends of the connector body 1. The mounting feet 12 are pre-matched with the diameter of the holes in the PCB board. The mounting feet 12 are inserted into the holes in the PCB board. The insertion process of the mounting feet 12 into the holes in the PCB board only requires a small auxiliary pushing force, which reduces the instantaneous impact vibration generated at the contact point between the mounting feet 12 and the PCB board from the initial assembly action. After the mounting feet 12 are fully inserted into the PCB board... After the board hole is formed, filler is injected into the groove 1221 on the bottom surface of the mounting foot 12. The filler will flow along the groove 1221 and fill the gap formed between the side wall of the mounting foot 12 and the PCB board hole. As the filler is continuously injected and solidified, the filler will generate a uniform lateral thrust on the side wall of the mounting foot 12, pushing the side wall of the mounting foot 12 to slowly expand outward, and finally make the mounting foot 12 and the PCB board hole form an interference fit. The entire outward expansion process of the filler is a flexible force transmission, which reduces the vibration impact on vibration-sensitive components and improves the assembly yield.

[0032] Reference Figure 2Specifically, the connector body 1 includes multiple connector housings 112. In this embodiment, four connector housings 112 are provided, arranged horizontally and integrally formed by injection molding, so that the four connector housings 112 together form a row housing 11. Two mounting feet 12 are fixedly disposed on the row housing 11, and the two mounting feet 12 are respectively arranged at both ends of the row housing 11. On the end face of the row housing 11 that is fixedly connected to the mounting feet 12, three positioning strips 15 are also provided. Two positioning strips 15 are fixedly connected to the side wall of the corresponding mounting feet 12, and the other positioning strip 15 is disposed in the middle position between the two mounting feet 12. The PCB board usually has a positioning groove, and the positioning strip 15 is inserted into the positioning groove.

[0033] Furthermore, when multiple interface configurations need to be implemented on the PCB board, compared to the traditional method of sequentially assembling multiple independent connector housings 112 to the PCB board, the process of installing the row housing 11 onto the PCB board can be directly operated on the entire row housing 11. First, the positioning strip 15 on the end face of the row housing 11 is engaged with the preset positioning slot on the PCB board to complete one positioning. Then, the two mounting feet 12 at both ends of the row housing 11 are simultaneously inserted into the holes on the PCB board. This allows the mounting structures corresponding to all connector housings 112 within the row housing 11 to be synchronously adapted to the preset mounting areas on the PCB board, reducing the number of times multiple independent RJ connectors need to be assembled, reducing the complexity of assembly operations, and improving assembly efficiency and space utilization.

[0034] Specifically, the mounting foot 12 includes a foot post 121 and a filling part 122. The foot post 121 is a cylindrical column structure, and the filling part 122 is a truncated cone shape, that is, a frustum of a cone with one narrow end and the other wide end. The side wall of the filling part 122 is an inclined structure, and the wide end face of the filling part 122 is fixedly connected to the foot post 121. The groove 1221 is provided on the narrow end face of the filling part 122. The groove 1221 extends along the circular diameter length direction of the narrow end face of the filling part 122 and passes through the side wall of the filling part 122 to form a through groove structure. In the embodiment of this application, the groove 1221 is a straight groove, and the groove 1221 is directly machined on the mounting foot 12.

[0035] This explains that, since the groove 1221 extends along the length of the bottom surface of the mounting foot 12, the coverage area of ​​the groove 1221 can match the main area of ​​the bottom surface of the mounting foot 12. At the same time, the groove 1221 is a through groove that penetrates the side wall of the mounting foot 12. Through the opening that penetrates the side wall of the mounting foot 12, it directly connects with the gap formed between the side wall of the mounting foot 12 and the PCB board hole. The internal space of the groove 1221 and the gap formed between the side wall of the mounting foot 12 and the PCB board hole form a channel through the through part of the side wall.

[0036] At this time, filler is injected into the groove 1221. The filler first spreads along the length of the groove 1221 on the bottom surface of the mounting foot 12. Then, since the groove 1221 penetrates the side wall of the mounting foot 12, the diffused filler can flow smoothly through the through opening in the side wall to the gap between the side wall of the mounting foot 12 and the PCB hole, forming a complete flow path from the groove 1221 to the through opening in the side wall, and then to the gap between the side wall of the mounting foot 12 and the PCB hole. This connection method, combined with the guiding effect of the inclined structure, allows the filler to be more evenly distributed along the gap between the side wall of the mounting foot 12 and the PCB hole. When the filler solidifies, it can push the side wall of the mounting foot 12 to expand evenly outward, ensuring that the mounting foot 12 and the PCB hole form a stable interference fit.

[0037] Furthermore, the filler is set as epoxy resin adhesive. Epoxy resin adhesive has excellent fluidity and is a low-viscosity liquid when uncured. It can spread smoothly along the tank 1221 and fill the gap between the mounting pin 12 and the PCB board hole through the through opening. After curing, it has high mechanical strength and can provide uniform lateral thrust to push the sidewall of the mounting pin 12 outward. The volume shrinkage during the curing process is small, which can reduce the gap residue caused by shrinkage and ensure the stability of the interference fit. At the same time, the bonding strength is high, which can enhance the connection reliability between the mounting pin 12 and the PCB board hole. It has high insulation resistance and can adapt to the long-term working environment of electronic equipment.

[0038] Furthermore, a pair of grounding solder feet 13 are provided at both ends of the row housing 11. Multiple connector housings 112 share a pair of grounding solder feet 13. Traditionally, independent connector housings 112 require a separate grounding solder foot 13 for each connector housing 112. Since the row housing 11 is integrally formed from multiple connector housings 112, providing a pair of grounding solder feet 13 at both ends of the row housing 11 can meet the grounding requirements of all connector housings 112 sharing the row housing 11, reducing the total number of grounding solder feet 13, simplifying the overall structure of the row housing 11, reducing the cost of metal materials and processing complexity, and reducing the number of assembly steps for the grounding solder feet 13, thereby improving assembly efficiency in multi-interface scenarios.

[0039] Reference Figure 3 and Figure 4 Furthermore, the grounding solder foot 13 includes a plug-in portion 131 and a grounding portion 132, and the row housing 11 is provided with a plug-in groove 111, as shown in the figure. Figure 4 One end of the plug-in part 131 is arc-shaped. The plug-in part 131 and the plug-in groove 111 form a plug-in fit. The arc-shaped end of the plug-in part 131 extends along the outer direction of the plug-in groove 111. The extension direction is towards the side away from the row housing 11, and finally it is fixedly connected to the grounding part 132, so that the grounding part 132 protrudes outward from the row housing 11.

[0040] Furthermore, the insertion part 131 and the insertion slot 111 are inserted into each other with an interference fit. The thickness of the insertion part 131 is greater than the thickness of the insertion part 131 in a traditional single connector. The interference fit between the insertion part 131 and the insertion slot 111 already provides basic connection tightness. The increased thickness of the insertion part 131 directly expands the contact area between the insertion part 131 and the insertion slot 111. The stability of the interference fit depends on... The friction and interlocking force generated by the contact between the plug part 131 and the plug groove 111 are such that the larger the contact area, the greater the friction under the unit external force, and the more difficult it is for the plug part 131 to be released from the plug groove 111. The thicker the plug part 131, the higher the structural strength and the stronger the resistance to deformation. During the process of inserting into the plug groove 111 during assembly, or when subjected to external forces such as vibration and impact during long-term use, it is not easy to have deformation problems such as bending or breakage, and can always maintain the interference fit with the plug groove 111.

[0041] Meanwhile, the grounding part 132 preferentially connects directly to the grounding pads pre-set on the PCB board. The surface flatness deviation of the grounding part 132 is less than 0.1mm. When the connector body 1 is assembled with the PCB board, the protruding grounding part 132 can preferentially form physical contact with the grounding pads pre-set on the PCB board, providing basic contact conditions for the conduction of grounding current. The surface flatness deviation of the grounding part 132 is less than 0.1mm, which reduces the situation of contact breaks or local suspension caused by unevenness of the surface of the grounding part 132. It allows the surface of the grounding part 132 to be uniformly attached to the grounding pads of the PCB board. This attachment state can effectively reduce contact resistance and ensure that the grounding current is conducted quickly and stably.

[0042] Reference Figure 5 In addition, the connector body 1 also includes multiple terminal structures 14, which are also set to four. The four terminal structures 14 correspond one-to-one with the four connector housings 112. The four terminal structures 14 are embedded in the connector housings 112 and can match the preset mounting slots of each connector housing 112 in the row housing 11. This ensures that after each terminal structure 14 is embedded in the corresponding connector housing 112, the position of each terminal structure 14 is consistent with the overall assembly requirements of the row housing 11. At the same time, the terminal structure 14 is embedded in the connector housing 112, so that the terminal structure 14 and the corresponding connector housing 112 are tightly connected. When the row housing 11 is synchronously adapted to the PCB board through one action, the terminal structure 14 in each connector housing 112 can also be synchronously adapted to the circuit pads on the PCB board.

[0043] Furthermore, the connector body 1 is mounted on the PCB board using surface mount technology. Surface mount technology can control the mounting position of the connector body 1 on the PCB board, reduce installation deviations, and ensure that the interface position of the connector body 1 is highly matched with the preset circuit layout of the PCB board and the adaptation path of external plug-in components. At the same time, surface mount technology can realize the synchronous mounting and soldering of the connector body 1 and other electronic components on the PCB board, reducing the need to set up a separate mounting station for the connector body 1 and shortening the total assembly time. Especially in mass production scenarios, it helps to reduce the assembly cost of the unit connector body 1 and improve production efficiency.

[0044] The implementation principle of an RJ connector structure in this application embodiment is as follows: First, the connector body 1 is initially positioned on the PCB board by the insertion and cooperation of the three positioning strips 15 on the connector housing 11 with the preset positioning slots on the PCB board, ensuring that the entire connector housing 11 is precisely aligned with the preset installation area on the PCB board, laying the foundation for subsequent assembly. The mounting feet 12 are preset matched with the hole diameters on the PCB board, and the insertion process only requires a small auxiliary pushing force. After the mounting feet 12 are fully inserted, filler is injected into the slot.

[0045] The filler is an epoxy resin adhesive that is a low-viscosity liquid when it is not cured. It diffuses along the length of the slot and, with the help of the opening through the side wall of the slot and the guiding effect of the inclined side wall of the filler part 122, flows smoothly into the gap between the side wall of the mounting foot 12 and the hole in the PCB board, forming a complete flow path from the slot to the side wall opening and then to the gap, so that the adhesive is evenly distributed. During the curing process, the filler generates a uniform lateral thrust, pushing the side wall of the mounting foot 12 to slowly expand outward, forming a stable interference fit. The cured filler ensures the stability of the interference fit and enhances the reliability of the connection.

[0046] Furthermore, the integrated structure of the row housing 11 allows multiple connector housings 112 to be simultaneously adapted to the PCB board mounting area in a single operation, driving each terminal structure 14 to be simultaneously adapted to the PCB board circuit pads, reducing the number of independent assembly operations, lowering operational complexity, and improving assembly efficiency and space utilization. The insertion part 131 of the grounding solder foot 13 forms an interference fit with the insertion slot 111 of the row housing 11. The thickness of the insertion part 131 is greater than that of the corresponding structure of a traditional single connector, resulting in a larger contact area, stronger friction and interlocking force, and better structural strength and deformation resistance, which can maintain a stable fit for a long time.

[0047] During assembly, the grounding part 132 preferentially forms physical contact with the preset grounding pad on the PCB board, and the surface flatness deviation of the grounding part 132 is less than 0.1mm, reducing contact breaks and suspension, achieving uniform fit, reducing contact resistance, and ensuring rapid and stable conduction of grounding current.

[0048] Finally, surface mount technology is used to complete the final installation of the connector body 1 and the PCB board. This allows for control of the installation position, reduction of deviations, and ensures a high degree of matching between the interface position and the PCB board circuit layout and the adaptation path of external plug-in components. At the same time, it can be simultaneously mounted and soldered with other electronic components, reducing the need for separate installation stations, shortening the total working time, reducing the unit assembly cost of mass production, and improving production efficiency.

[0049] The above are all preferred embodiments 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.
