[0002] With the rapid development of information technology, the internet has deeply integrated into all aspects of social life. Whether it's personal online shopping and social interaction, or online office work, data storage and transmission for businesses, or the operation of critical national infrastructure systems such as power, transportation, and finance, all rely heavily on networks. This makes network interface modules, as the bridge connecting network devices and the network, increasingly important. They need to meet the high-speed and stable data transmission requirements in different scenarios, ensuring that various devices can efficiently access the network and exchange data.

[0003] Current network interface modules mainly suffer from three problems: First, their physical structure lacks effective protection and is easily damaged by accidental bumps or environmental factors; second, the housing and mounting bracket adopt a separate structure, and the plug-in design of the module interface is not user-friendly, making operation inconvenient and resulting in a poor user experience; finally, and most importantly, their data transmission efficiency is low, which has become a bottleneck for network performance and seriously affects normal use. Summary of the Invention

[0004] The purpose of this invention is to provide a network interface module device to solve the problems mentioned in the background art.

The bottom of the needle holder is fitted with a transparent cover, and the top of the housing is fitted with a protective component for protecting the connector. The gold needle assembly includes gold needles and a fixing block. The fixing block is interlocked with the bracket. Multiple gold needles are fixedly connected to the top surface of the fixing block. The multiple gold needles are designed to cross each other, with their intersection points on the same horizontal line and their highest points on the same horizontal line. A mounting bracket is fixedly connected to the top of the housing, and the housing and the mounting bracket are designed as an integral molded structure. Labeling positions are provided on both sides of the outer wall of the needle holder, and labels are provided at the labeling positions.

[0006] Preferably, the two ends of the fixing block are fixedly connected to the snap-fit ​​blocks, the two ends of the inner wall of the bracket are provided with snap-fit ​​cavities at the bottom, and the snap-fit ​​cavities are snap-fitted to the snap-fit ​​blocks. The bracket surface is provided with a contact port above it, and the contact port communicates with the insertion port. The top of the contact port is horizontally arranged with a partition plate for separating adjacent gold needles.

[0007] Preferably, the protective assembly includes a protective door and a spring. The protective door is in movable contact with the top of the housing at the insertion port.

[0010] Beneficial effects

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model solves the problem of insufficient protection of existing modules through a dual protection design: On the one hand, the shell and the mounting bracket adopt an integrated molding structure, which greatly improves the structural strength compared with the spliced ​​shell. It can effectively reduce the thickness between the top surface of the shell 1 and the mounting point while improving the overall structural strength and impact resistance, reducing the risk of damage caused by accidental bumps, and also improving the operability and user experience when plugging and unplugging the crystal head; On the other hand, the top of the shell is equipped with a protective component consisting of a protective door, a spring and a guide rod. When not in use, the spring can drive the protective door to automatically close the connector, which can not only prevent dust and water stains from entering the shell and contaminating the gold needle component and circuit board, but also prevent foreign objects from hitting the gold needle and causing deformation of the contact end, significantly improving the adaptability of the device in complex environments and extending the service life of the core components.

[0013] 2. This utility model effectively solves the problem of low transmission efficiency in existing modules by optimizing the connection structure between the gold pin assembly and the circuit: the gold pin assembly adopts a cross design and the highest points of multiple gold pins are on the same horizontal line. This structure ensures that when the external connector is inserted, each gold pin can form a sufficient and uniform contact area with the connector contact point, reducing contact resistance and reducing contact loss during signal transmission; at the same time, a fisheye structure is opened at one end of the chuck in the pin holder, which tightly connects to the surface of the circuit board. Compared with the traditional soldering connection, this reduces the risk of loose connection, and the fisheye structure can accommodate the slight displacement of the circuit board, ensuring the stability of signal transmission, thereby improving the overall data transmission rate and meeting the needs of high-speed data interaction scenarios.

[0014] 3. This utility model achieves low insertion loss, low return loss, low propagation delay, and reduced crosstalk by setting multiple corresponding card-shaped connection holes and multiple gold-pin connection holes according to the TIA / EIA568A and TIA / EIA568B standard wiring sequences, and by setting multiple different crosstalk group arrangements between wire pairs on both sides of the main component of the circuit board. This enables the circuit board to meet the transmission performance requirements of CAT6 and CAT6A. Attached Figure Description

[0032] Example 1

[0033] like Figure 1-8 This is a schematic diagram of a network interface module device according to a preferred embodiment of the present invention. In this embodiment, the present invention provides a network interface module device, including a housing 1, a gold pin assembly 2, a bracket 3, a circuit board 4, a protective assembly 5, a pin holder 6, a transparent cover 7, a card cutter 8, and a label 9.

[0034] In this embodiment, as Figures 1-2As shown, the top surface of the housing 1 has a connector 11 for connecting an external network connector. The housing 1 and the mounting bracket 14 adopt an integrated molding structure design, which can effectively reduce the thickness between the top surface of the housing 1 and the mounting point while improving the overall structural strength and impact resistance, reducing the risk of damage caused by accidental bumps, and also improving the operability and user experience when plugging and unplugging the RJ45 connector. A bracket 3 is fixedly connected inside the housing 1, and the bracket 3 is installed in the housing 1 by snap-fit ​​or screw fixing. A gold pin assembly 2 is snapped into the bracket 3, and the top of the gold pin assembly 2 is set in the connector 11 for contact with the external connector. A pin holder 6 is snapped into the bottom of the housing 1, and a circuit board 4 is installed in the pin holder 6 near one end of the housing 1. The surface of the circuit board 4 is electrically connected to the bottom of the gold pin assembly 2 by crimping to realize signal transmission. Multiple clips 8 are distributed on the bottom surface of the pin holder 6. The top of the clips 8 passes through the pin holder 6 and is fixed and electrically connected to the bottom surface of the circuit board 4 by crimping. A transparent cover 7 is snapped onto the bottom of the pin holder 6 to protect the internal components, facilitate observation, and prevent the network cable from falling out. A protective component 5 is installed on the top of the housing 1 to protect the connector 11 from dust, foreign objects, damage to the gold pin assembly 2, and oxidation of the gold pin assembly 2.

[0035] In this embodiment, as Figure 4 and Figure 6 As shown, the gold needle assembly 2 includes a fixing block 21 and multiple gold needles 22. The fixing block 21 is interlocked with the bracket 3. Specifically, the two end faces of the fixing block 21 are fixedly connected to the interlocking blocks 23, and the two ends of the inner wall of the bracket 3 are provided with interlocking cavities 33 at the bottom. The interlocking blocks 23 and the interlocking cavities 33 are interlocked to achieve quick installation and fixation of the gold needle assembly 2. Multiple gold needles 22 are fixedly connected to the top surface of the fixing block 21, and the top of the gold needles 22 is located inside the connector 11. The multiple gold needles 22 adopt a cross design, with their intersection points on the same horizontal line, and the highest points of all gold needles 22 are on the same horizontal line. This design ensures that when the external connector is inserted, each gold needle 22 can form a sufficient and uniform contact area with the connector contact, reducing contact resistance, improving signal transmission stability, and meeting the requirements of CAT6 and CAT6A transmission performance. A contact port 31 is provided on the upper surface of the bracket 3, which communicates with the connector 11 to facilitate the exposure of the gold needles 22. A partition plate 32 is fixedly connected to the top of the contact port 31 in a horizontal arrangement. The partition plate 32 is used to separate adjacent gold needles 22 to prevent short circuits or mutual interference between the gold needles 22.

[0036] In this embodiment, as Figure 3 and Figure 5As shown, the protective assembly 5 includes a protective door 51 and a spring 52. The protective door 51 is in contact with the top of the housing 1 at the connector 11, and is used to open and close the connector 11. A compression groove 12 is provided at one end of the top of the housing 1 at the connector 11, and a first guide rod 13 is fixedly connected to the end of the compression groove 12 away from the connector 11. The spring 52 is disposed in the compression groove 12, and one end of the spring 52 is sleeved on the outer wall surface of the first guide rod 13. A second guide rod 53 is fixedly connected to the bottom of the protective door 51, and the other end of the spring 52 is sleeved on the outer wall surface of the second guide rod 53. When the external connector is not inserted, the elastic force of the spring 52 drives the protective door 51 to close the connector 11, preventing dust or foreign objects from entering; when the external connector is inserted, the protective door 51 is pushed open, the spring 52 is compressed, and the protective door 51 automatically resets after the connector is pulled out.

[0037] In this embodiment, as Figure 2 , Figure 7 and Figure 8 One end of the gold needle 22 has a gold needle eye 24, and multiple gold needle connection holes 41 are evenly distributed in the middle of the surface of the circuit board 4. The gold needle eye 24 is connected to the gold needle connection hole 41 to achieve electrical connection. One end of the card cutter 8 has a card cutter eye 81, and multiple card cutter connection holes 42 are evenly distributed on the outer side of the surface of the circuit board 4. The card cutter eye 81 is connected to the card cutter connection hole 42. By setting multiple corresponding card-type connector holes and multiple gold-pin connector holes according to the TIA / EIA568A and TIA / EIA568B standard wiring sequences, and by setting multiple different crosstalk group arrangements between wire pairs on both sides of the main component of the circuit board 4, the functions of low insertion loss, low return loss, low propagation delay, and reduced crosstalk are achieved, enabling the circuit board to meet the transmission performance requirements of CAT6 and CAT6A. The gold-pin connector hole 41 and the card-type connector hole 42 are electrically connected in a one-to-one correspondence, so that the signal is transmitted from the gold-pin 22 to the circuit board 4, and then led out to the external line through the card-type connector 8, which plays a role in compensating between lines and improving transmission performance. The gold-pin fisheye 24 and the card-type fisheye 81 structure provide elastic contact to ensure a tight connection with the circuit board 4, reduce the risk of loose connection, and accommodate the slight displacement of the circuit board 4, thereby improving connection reliability.

[0038] In this embodiment, as Figure 2 As shown, label positions 61 are provided on both sides of the outer wall of the pin holder 6. Label positions 61 are provided with labels 9, which are marked with two wiring methods, 568A and 568B, to meet different termination requirements, as well as markings indicating the product categories CAT6 and CAT6A.

[0039] Example 2

[0040] Based on Example 1, such as Figure 9As shown, this embodiment further optimizes the structure of the network interface module device housing 1. The structure of housing 1 is existing technology. The housing 1 is also provided with a snap-fit ​​assembly, which includes an inclined snap-fit ​​block located on one side of the housing 1 and an elastic buckle located on the other side of the inclined snap-fit ​​block. Other structures and assembly methods are the same as in Embodiment 1.

[0041] Working principle:

[0042] In use, the external network connector is inserted into the socket 11, the protective door 51 is pushed open, and it comes into contact with the gold pins 22 of the gold pin assembly 2. The cross-shaped design of the gold pins 22 ensures that all pins make simultaneous and uniform contact, reducing signal loss. The signal is transmitted to the circuit board 4 through the gold pins 22, and then led out to the external circuit through the fisheye structure 81 of the clip 8. The protective assembly 5 automatically closes after the connector is pulled out, keeping the inside of the socket 11 clean. The one-piece molded structure of the housing 1 enhances durability, and the transparent cover 7 facilitates observation of the internal status. The overall device has the advantages of strong protection, high transmission efficiency, and simple operation.
