Description

Technical Field

[0001] This invention relates to the field of connector technology, and more particularly to an improved multi-port network connector. Background Technology

[0002] Connectors are indispensable components in electronic devices. Their forms and structures vary depending on the application, frequency, power, and environment, resulting in a wide variety of connector types. The primary function of connectors is to bridge gaps in circuits or connect isolated circuits, allowing current to flow and enabling the circuit to perform its intended function.

[0003] In network connectivity technology, network connectors serve as bridges for data transmission. The most common type is the RJ45 network port, widely used in daily life. When connecting external electronic devices, connectors with integrated network interfaces are employed, significantly improving convenience in certain office environments or emergency situations. However, with the trend towards smaller, thinner electronic products, and in environments with more people, such as conference rooms, broadband switches, hubs, servers, and communication applications, traditional bulky network connectors with fewer ports can no longer meet user needs.

[0004] Currently, most multi-port connectors used in the industry are formed by combining multiple individual components into one piece. For example, the early Chinese patent CN208782143U (titled "A Waterproof and Dustproof RJ45 Network Port") uses multiple copper shells to cover the upper part of the corresponding ferrule on a one-to-one basis to prevent electromagnetic interference. Such a design requires many components and is complex to manufacture, which is not conducive to reducing costs and improving product yield.

[0005] To address the aforementioned issues, the applicant has provided a multi-port connector in Chinese patent CN202022487757.1. Although it solves the technical problems of compression, consolidation, and shielding, the design of the shielding sheet makes its processing relatively complex, and the presence of the shielding sheet makes its installation relatively complex. Moreover, for connectors that require a multi-layer structure in the vertical direction, it results in a complex structure and low integration. Summary of the Invention

[0006] This invention provides an improved multi-port network connection that can realize multi-layer multi-port network port connection. By utilizing the structural design of longitudinal and transverse partitions, it can not only effectively improve the shielding effect between each port, but also effectively reduce its processing and assembly costs.

[0007] According to one aspect of the present invention, an improved multi-port network connector is provided, comprising a PCB base plate, transverse partitions, and a light guide mounted on a base. The light guide is vertically mounted on the PCB base plate, and a longitudinal partition parallel to the light guide is mounted in the middle of the PCB base plate. Main PCB boards are mounted parallel to each other on both sides of the longitudinal partitions. The transverse partitions are mounted parallel to each other on the main PCB boards at intervals and form a mounting cavity with the PCB base plate. A module housing is installed in the mounting cavity. Terminal modules are mounted at intervals on the main PCB boards, and the terminal modules are electrically connected to the PCB base plate through the main PCB boards.

[0008] Based on the above scheme, the light guide is preferably L-shaped and connected by a connecting conductor.

[0009] Based on the above solution, preferably, the base is provided with a positioning body, and the positioning body has a slot in the middle, which is adapted to the connecting conductor.

[0010] Preferably, based on the above scheme, the module shell has a rectangular frame structure, and the bottom, top and one of the side end faces of the module shell are respectively provided with connection terminals.

[0011] Based on the above scheme, the bottom end of the module shell extends outward to form a snap-fit ​​flange, and a POE adapter module is installed on the snap-fit ​​flange.

[0012] Based on the above scheme, preferably, the top of the module shell is recessed downward to form a recessed groove for accommodating the POE coil, and the middle of the side end of the module shell is recessed inward to form a cavity for accommodating the transformer coil.

[0013] Based on the above-mentioned scheme, the preferred embodiment further includes an insulating shell, which is U-shaped and covers the outside of the two light guides. A front plate is provided on the insulating shell, and the front plate is provided with a socket corresponding to the terminal module.

[0014] In a preferred embodiment of the above scheme, the insulating shell is further covered with a metal shielding shell.

[0015] This invention discloses an improved multi-port network connector. Through a structural design employing a PCB base plate and horizontal and vertical partitions, multiple mutually isolated mounting cavities are formed. Module shells are installed within these cavities, and terminal modules are spaced apart on the PCB board and electrically connected to the main PCB board and the PCB base plate. This not only enables the stacking of multiple ports, improving the product's shielding effect, but also, due to the design of the vertical partitions, achieves spatial isolation on both sides with a single partition, avoiding the technical problems of complex processing and high costs caused by connecting multiple partitions and insulating shells.

[0030] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0031] Please see Figure 1 and combined Figure 2 and Figure 3 As shown, the improved multi-port network connector provided by the present invention includes a PCB base plate 2, a transverse partition 3 and a light guide 4 mounted on a base 1. The base 1 is a plastic base 1, which provides a mounting foundation for the PCB base plate 2.

[0032] Specifically, the light guide 4 is vertically mounted on both sides of the PCB base plate 2, and a longitudinal partition 5 is mounted in the middle of the PCB base plate 2, which is parallel to the light guide 4. The main PCB board 6 is mounted on both sides of the longitudinal partition 5, that is, the same PCB base plate 2 is divided into two parts by the longitudinal partition 5. In actual use, multiple longitudinal partitions 5 can be set according to actual needs.

[0033] The present invention uses multiple transverse partitions 3. In an embodiment of the present invention, there are four transverse partitions 3, which are divided into two groups and vertically installed on both sides of the main PCB board 6 and vertically connected to the PCB base plate 2. In this case, the four transverse partitions 3, the main PCB board 6, and the PCB base plate 2 form six mounting cavities 7. Six module shells 8 are installed in the mounting cavities 7. Three terminal modules 9 are installed on each main PCB board 6. Each terminal module 9 is electrically connected to the POE coil in the module shell 8 through the main PCB board 6. For the specific structure, please refer to [link / reference]. Figure 4 As shown.

[0034] It is worth noting that during production, the number of transverse partitions 3 in this invention can be set according to actual needs, and the number of terminal modules 9 on the main PCB board 6 corresponds to the number of mounting cavities 7 formed by the transverse partitions 3, such as... Figure 5 As shown.

[0035] Of course, depending on actual needs, there can be multiple longitudinal partitions 5 of the present invention, but each longitudinal partition 5 has a main PCB board 6 on both sides, so an even number of plug-in ports can be formed.

[0036] Compared with existing multi-port network connectors, this invention uses a PCB base plate 2 to form an even number of mounting cavities 7 with multiple longitudinal partitions 5 and transverse partitions 3, and installs multiple different module shells 8, corresponding to an even number of terminal modules 9, thereby realizing the design of a multi-port network connector. Its structure is simple, installation is convenient and quick, and its cost is low. Moreover, due to the function of the mounting cavity 7, the electrical components in the module shell 8 can be isolated from each other, ensuring the shielding effect between each port, and effectively reducing its processing and assembly costs.

[0037] like Figure 3 As shown, the module housing 8 of the present invention has a rectangular frame structure. Connection terminals 81 are respectively provided on the bottom, top, and one side end face of the module housing 8. The bottom of the module housing 8 is electrically connected to the PCB base plate 2 via the connection terminal 81, and the connection terminals 81 on the side end face of the module housing 8 are electrically connected to the main PCB board 6. That is, through the connection terminals 81 on the module housing 8, electrical components inside the module housing 8 can be electrically connected to the main PCB board 6 and the PCB base plate 2, such as... Figure 6 As shown.

[0038] In order to achieve electrical connection between the POE coil and the PCB base plate 2 and the main PCB board 6, the bottom end of the module shell 8 of the present invention extends outward to form a snap-fit ​​flange 82. The snap-fit ​​flange 82 is equipped with a POE adapter module 83, so that each terminal module 9 is connected to a corresponding module shell 8, thereby reducing the size of the multi-port network connector.

[0039] In this invention, the top center of the module shell 8 is recessed downward to form a recessed groove 84 for accommodating the POE coil, and the middle of the side end of the module shell 8 is recessed inward to form a cavity 85 for accommodating the transformer coil, so as to further reduce the volume occupied by the POE coil and the transformer coil.

[0040] In order to make the power-on observable after the port is connected, the present invention makes the light guide 4 L-shaped and connected by a connecting conductor. That is, the number of light guides 4 is adapted to the number of terminal modules 9, and multiple light guides 4 are arranged in parallel to each other. When the terminal module 9 is connected, the light guide 4 emits light to indicate its power-on state.

[0041] Specifically, the present invention also provides a positioning body 10 on the base 1, and a slot 11 is provided in the middle of the positioning body 10. The slot 11 is adapted to the connecting conductor. That is, through the design of the slot 11, on the one hand, the requirements for interconnection of the light guides 4 can be met, and the strength of the light guides 4 can be improved. On the other hand, through the design of the slot 11, the space occupied by the light guides 4 can be reduced, and their volume can be reduced.

[0042] The improved multi-port network connector of the present invention further includes an insulating shell 20, which is U-shaped and covers the outside of the two light guides 4. A front plate 201 is provided on the insulating shell 20, and the front plate 201 is provided with a socket 202 corresponding to the terminal module 9. Preferably, the insulating shell 20 of the present invention is also covered with a metal shielding shell.

[0043] The terminal module 9 of the present invention includes a terminal group 91 composed of several terminals and a circuit board 92. Multiple terminals are connected to form an integral structure embedded in the circuit board 92. Each terminal includes a rear-end pin 911, a straight segment 912 embedded in the circuit board 92, an arc-shaped connecting segment 913, and a front-end pin 914 connected in sequence. The rear-end pin 911 is parallel to the straight segment 912, and a vertical connecting segment 915 is provided between the rear-end pin 911 and the straight segment 912, creating a height difference between the straight segment 912 and the rear-end pin 911. The arc-shaped connecting segment 913 is set at an angle greater than 90° and less than 180°, creating an acute angle between the front-end pin 914 and the straight segment 912 to form an inclined angle conducive to multi-plug insertion. Please refer to [link to relevant documentation]. Figure 7 As shown.

[0044] This invention discloses an improved multi-port network connector. Through a structural design employing a PCB base plate 2 with horizontal partitions 3 and vertical partitions 5, multiple mutually isolated mounting cavities 7 are formed. Module shells 8 are installed within the mounting cavities 7. Terminal modules 9 are spaced apart on the PCB board and electrically connected to the main PCB board 6 and the PCB base plate 2. This not only enables the stacking of multiple ports, improving the product's shielding effect, but also, due to the design of the vertical partitions 5, achieves spatial isolation on both sides with a single partition, avoiding the technical problems of complex processing and high cost caused by connecting multiple partitions to the insulating shell 20.

[0045] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0046] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
