Technical Field
[0001] The utility model relates to the technical field of connectors, in particular to a connector pin with firm connection. Background Art
[0002] With the large-scale popularization of products for LAN applications, the RJ45 network connector socket, as a standard configuration for wired LAN networks and a key component, its characteristics must also meet the new requirements of the next-generation Ethernet. In terms of servers and routers, the RJ45 network connector socket needs to further meet the requirements of high speed and high reliability. Laptops, digital TVs, HDD recorders, and game consoles have the need for further miniaturization and ultra-thinness. In particular, current laptops and all-in-one computers have an increasingly high demand for thinness and lightness, and the requirements for the RJ45 network connector socket will be higher and higher, and the demand will also be larger and larger.
[0003] However, for existing laptops, digital TVs, HDD recorders, game consoles, etc., the current standard height (13.6 mm) of the RJ45 network connector socket often becomes the biggest problem point that must be solved on the road to pursuing thinness and lightness. Summary of the Utility Model
[0004] Aiming at the above-mentioned disadvantages of the existing technology, the purpose of the utility model is to provide a sunken RJ45 network connector socket with a simple structure, which can reduce the height protruding from the circuit board surface, has good parallelism of pins, and is convenient for insertion and soldering.
[0005] The technical solution adopted by the utility model to solve its technical problems is a sunken RJ network socket, including a socket housing and pins. The front of the socket housing is provided with an insertion interface, the back of the socket housing is provided with an installation groove, the bottom of the installation groove is communicated with the bottom surface of the insertion interface. The pins are provided with a contact section, a plugging section, and a connection section. The contact section is arranged in parallel and inclined backward and upward in the insertion interface, the plugging section is arranged in parallel and vertically downward outside the rear end of the insertion interface, the connection section connects the contact section and the plugging section, the connection section is fixedly arranged with the installation groove. The back of the socket housing below the top of the installation groove is provided with a notch. The connection section is arranged along the extending direction of the installation groove, and a pin retaining seat is also connected in the notch. The pin retaining seat includes a vertical rear retaining part and a horizontal upper retaining part. The rear retaining part is arranged corresponding to the front wall surface of the notch and is provided with a corresponding pin avoidance cavity. The upper retaining part is arranged corresponding to the upper wall surface of the notch and is used for inserting and fixing and limiting the plugging section.
[0006] Advantages of adopting the above technical solution: By opening a notch at a corresponding position on the back of the socket housing, the lower part of the end of the socket housing with the insertion interface can be embedded in the circuit board, thereby reducing the height of the RJ network socket protruding from the surface of the circuit board. Therefore, electronic products such as laptops, digital TVs, HDD recorders, and game consoles can be made thinner without being restricted by the RJ45 network socket. And due to the setting of the notch, in order to make the structure of the pin more reasonable, the connecting section of the pin will be in a bent structure that fits the installation groove. At this time, by setting a pin retainer composed of a rear retaining portion and an upper retaining portion in the notch, the rear retaining portion and the upper retaining portion can form installation positioning for the part of the connecting section in the notch. The installation effect of the pin is good and it will not be overly exposed. At the same time, it can also limit the insertion section, preventing the insertion section from deforming under circumstances such as turnover transportation or collision, ensuring that the insertion section has good position accuracy and parallelism, and facilitating connection with the PCB board. Therefore, the overall structure is simple, and at the same time, the height protruding from the surface of the circuit board can be reduced, and the parallelism is good, facilitating insertion and welding.
[0007] Further, on both sides of the back of the socket housing above the notch, recessed portions are respectively formed. The recessed portions are communicated with the notch and internally provided with protrusions with card slots. At corresponding positions of the upper retaining portion, hooks are provided, and the hooks are engaged with the card slots on the protrusions.
[0008] Advantages of adopting the above technical solution: The setting of the recessed portions can effectively reduce the molding cost, and the protrusions with card slots are arranged in the recessed portions, so as to achieve the purpose of detachable installation of the pin retainer through the cooperation of the hooks and the card slots, and the structural position design is also reasonable.
[0009] Further, on the inner side of the upper wall surface of the notch relative to the recessed portion, a pair of positioning slots are formed. On the upper retaining portion, positioning blocks inserted into the positioning slots are provided.
[0010] Advantages of adopting the above technical solution: Through the cooperation of the positioning slots and the positioning blocks, the installation of the pin retainer is more stable, and the structural design is reasonable.
[0011] Further, on the front of the socket housing, indicator light grooves are formed on both sides of the insertion interface. The indicator light grooves are used for installing indicator lights and are correspondingly arranged with the recessed portions. The side surface of the protrusion opposite to the recessed portion cooperates to form a pin groove, and the pins of the indicator light pass through the pin groove and are fixed on the upper retaining portion.
[0012] The advantages of adopting the above technical solution are as follows: by installing the indicator light in the indicator light slot, the network socket can display the connection status, and the protrusion and the recessed portion are used to form a pin slot for installing the indicator light pin. Therefore, no additional mounting structure is required on the network socket, thereby optimizing the overall volume, achieving a reasonable structure, and the pins are fixed on the upper stopper, with good parallelism.
[0013] Furthermore, the connecting section is provided with an arc-shaped protrusion in the plug-in port, and the protrusion is relatively located at 1 / 2 of the length of the contact section.
[0014] The advantages of adopting the above technical solution are: the setting of the raised part makes the overall elastic effect of the pin better, and after the crystal head is inserted into the plug interface, it forms a pressure on the contact section, and the raised part also has the function of providing support for the contact section to ensure stable contact between the two.
[0015] Furthermore, a fixing opening cooperating with the adjustment handle of the crystal plug is provided on the front side of the socket housing above the plug interface, and anti-dropping blocks are symmetrically provided in the opening direction of the fixing opening.
[0016] The advantages of adopting the above technical solution are as follows: when connecting the crystal head, adjust the adjustment handle on the crystal head so that the upper end of the crystal head is deformed to avoid the anti-dropping block, and then loosen the adjustment handle and limit it in the fixed mouth with the anti-dropping block, so that the crystal head is fixed in the plug interface. When the crystal head is in the plug interface, the adjustment handle is in a natural state and will not be affected by the force of the network cable interface. Therefore, the structure is stable and not easy to be damaged. The symmetrically arranged anti-dropping blocks are more stable when connecting the crystal head, avoiding the crystal head from tilting.
[0017] Furthermore, the network socket also includes a shielding shell covering the outside of the socket shell, and the shielding shell is formed with plug pins and grounding springs.
[0018] The advantages of adopting the above technical solution are as follows: by setting a shielding cover, interference from external signals can be effectively prevented; by setting plug pins, the connection between the network socket and the PCB board is made more secure; by setting a grounding spring sheet in contact with the metal outer casing, a grounding effect is achieved, making it safer to use.
[0019] Furthermore, the left and right sides of the shielding shell are provided with clamping springs extending into the plug interface for contacting the crystal head, and the corresponding side wall surface of the plug interface is also provided with a clearance groove matching the clamping springs.
[0020] The advantages of adopting the above technical solution are as follows: as the crystal head is inserted, the clamping spring generates an elastic clamping force, thereby making the crystal head more firmly fixed. The setting of the yield groove prevents the clamping spring from being fixed to the inner wall surface of the plug interface, making it more reasonable to use.
[0021] Furthermore, limiting bumps are provided on both sides of the socket housing and pass through the shielding cover to form a limit.
[0022] Advantages of adopting the above technical solution: The limiting bumps on both sides of the socket housing limit the position of the shielding cover on the socket housing, making the connection between the shielding cover and the socket housing more stable, and preventing the shielding cover from falling off during product use and thus affecting the product's use.

Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings, and other embodiments can be obtained. Additionally, the terms related to orientation only represent the relative positional relationship between components, rather than the absolute positional relationship.
[0032] Please refer to Figures 1 to 7 As shown, a surface-mounted RJ network socket includes a socket housing 1 and pins 2. An insertion interface 3 is provided on the front surface of the socket housing 1, and a mounting groove 4 is provided on the back surface of the socket housing 1. The bottom of the mounting groove 4 is in communication with the bottom surface of the insertion interface 3. The pins 2 are provided with a contact section 5, a plug-in section 6, and a connection section 7. The contact section 5 is arranged in parallel and obliquely upward backward within the insertion interface 3. The contact section 5 is combined with the crystal head. The plug-in section 6 is arranged in parallel and vertically downward outside the rear end of the insertion interface 6. The plug-in section 6 is connected to the PCB board. The connection section 7 connects the contact section 5 and the plug-in section 6, and the connection section 7 is fixedly arranged in the mounting groove 4.
[0033] In this embodiment, a notch 8 is provided below the top of the mounting groove 4 on the back surface of the socket housing 1. By providing a notch 8 at the corresponding position on the back surface of the socket housing 1, the lower part of the end of the socket housing 1 provided with the insertion interface 3 can be embedded in the circuit board, thereby reducing the height of the RJ network socket protruding from the surface of the circuit board. Therefore, electronic products such as notebook computers, digital TVs, HDD recorders, and game consoles can be made thinner without being restricted by the RJ45 network socket. And due to the setting of the notch 8, in order to make the structure of the pin 2 more reasonable, the connecting section 7 is arranged along the extending direction of the mounting groove 4. That is to say, the connecting section 7 of the pin 2 will have a bent structure that matches the mounting groove 4. More specifically, the head end of the connecting section 7 is fixedly arranged with the mounting groove 4 on the bottom surface of the insertion interface 3, the middle section of the connecting section 7 will be bent upward and is arranged relative to the mounting groove 4 on the rear end of the insertion interface 3 at an interval (the free end of the inclined contact section 5 will be limited and abutted in the mounting groove 4 on the rear end of the insertion interface 3), and the tail end of the connecting section 7 is fixedly arranged with the mounting groove 4 at the upper wall surface of the notch 8. In order to make the connection between the pin 2 and the PCB more convenient and stable, a pin retaining seat 9 is also connected in the notch 8. The pin retaining seat 9 includes a vertical rear retaining portion 10 and a horizontal upper retaining portion 11. The rear retaining portion 10 is arranged corresponding to the front wall surface of the notch 8 and is provided with a corresponding pin avoidance cavity 12. The setting of the pin avoidance cavity 12 makes it impossible to form interference after the rear retaining portion 10 is installed. The upper retaining portion 11 is arranged corresponding to the upper wall surface of the notch 8 and is used for inserting and fixing and limiting the insertion section 6. By providing the pin retaining seat 9 composed of the rear retaining portion 10 and the upper retaining portion 11 in the notch 8, the rear retaining portion 10 and the upper retaining portion 11 can form installation positioning for the part of the connecting section 7 in the notch 8. The installation effect of the pin 2 is good, and it will not be overly exposed. At the same time, it can also limit the insertion section 6, which can prevent the insertion section 6 from being deformed in the case of turnover transportation, collision, etc., and ensure that the insertion section 6 has good position accuracy and parallelism, which is convenient for connection with the PCB board. Therefore, the overall structure is simple, and at the same time, the height protruding from the surface of the circuit board can be reduced, and the parallelism is good, which is convenient for insertion and welding.
[0034] In this embodiment, recessed portions 13 are respectively formed on both sides above the notch 8 on the back surface of the socket housing 1. The recessed portions 13 are communicated with the notch 8 and are internally provided with protrusions 14 with card slots 15. Hooks 16 are provided at the corresponding positions of the upper retaining portion 11. The hooks 16 are engaged with the card slots 15 on the protrusions 14. The setting of the recessed portions 13 can effectively reduce the molding cost, and the protrusions 14 with card slots 15 are arranged in the recessed portions 13, so as to achieve the purpose of detachable installation of the pin retaining seat 9 through the cooperation of the hooks 16 and the card slots 15, and the structural position design is also reasonable.
[0035] In this embodiment, a pair of positioning slots 17 are formed on the upper wall surface of the notch 8 relative to the inner side of the recess 13. The positioning slots 17 are also distributed left and right. A positioning block 18 inserted into the positioning slots 17 is provided on the upper blocking portion 11. Through the cooperation of the positioning slots 17 and the positioning block 18, the installation of the pin blocking seat 9 is more stable, and the structural design is reasonable.
[0036] In this embodiment, on the front surface of the socket housing 1, indicator light grooves 19 are formed on both sides of the insertion interface 3. The indicator light grooves 19 are used to install the indicator lights 20 and are correspondingly arranged with the recess 13. The side surface of the convex block 14 opposite to the recess 13 cooperates to form a pin groove 21. More specifically, two pin grooves 21 are formed by the cooperation of the two side surfaces of the convex block 14 and the two side surfaces of the recess 13. The two pins of the indicator light 20 are fixedly penetrated through the two pin grooves 21 on the upper blocking portion 11. By installing the indicator light 20 in the indicator light groove 19, the network socket has the purpose of displaying the connection status, and the pin groove 21 for installing the pins of the indicator light 20 is formed by the convex block 14 and the recess 13. Therefore, no additional installation structure needs to be provided on the network socket, the overall volume is optimized, the structure is reasonable, and the pins are fixedly penetrated on the upper blocking portion with good parallelism.
[0037] In this embodiment, the connecting section 7 is provided with an arc-shaped protruding portion 22 in the insertion interface 3. The protruding portion 22 is relatively located at the midpoint of the length of the contact section 5. The protruding portion 22 does not protrude out of the installation groove 4. The setting of the protruding portion 22 makes the overall elastic effect of the pins 2 better, and after the crystal head is inserted into the insertion interface, it can form a pressing force on the contact section 5. The protruding portion 22 also has the function of providing support for the contact section 5 to ensure stable contact between the two.
[0038] In this embodiment, a fixing opening 23 for cooperating with the adjustment handle of the crystal head is provided above the insertion interface 3 on the front surface of the socket housing 1. Anti-detachment blocks 24 are symmetrically provided in the opening direction of the fixing opening 23. When connecting the crystal head, adjust the adjustment handle on the crystal head so that the upper end position of the crystal head is deformed to avoid the anti-detachment blocks 24, and then release the adjustment handle and it is limited by the anti-detachment blocks in the fixing opening, so that the crystal head is fixed in the insertion interface. When the crystal head is in the insertion interface, the adjustment handle is in a natural state and will not be affected by the acting force of the network cable interface. Therefore, the structure is stable and not easily damaged. The symmetrically arranged anti-detachment blocks 24 are more stable when connecting the crystal head and prevent the crystal head from tilting.
[0039] In this embodiment, the network socket further includes a shielding cover 25 covering the outside of the socket housing 1. Plug-in pins 26 and grounding elastic pieces 27 are formed on the shielding cover 25. By providing the shielding cover 25, external signal interference is effectively prevented. By providing the plug-in pins 26, the connection between the network socket and the PCB board is made more firm. By providing the grounding elastic pieces 27 in contact with the metal outer casing, the grounding function is realized, making the use safer.
[0040] In this embodiment, the left and right sides of the shielding shell 25 are provided with clamping springs 28 extending into the plug interface 3 for contacting the crystal head. The corresponding side wall surface of the plug interface 3 is also provided with a clearance groove 29 that cooperates with the clamping spring 28. As the crystal head is inserted, the clamping spring 28 generates an elastic clamping force, thereby making the crystal head more firmly fixed. The provision of the clearance groove 29 avoids the clamping spring 28 from being fixed to the inner wall surface of the plug interface 3, which is more reasonable to use. More specifically, the positioning slot 17 corresponds to and is connected to the clearance groove 29.
[0041] In this embodiment, both sides of the socket shell 1 are further provided with limiting protrusions 30 that pass through the shielding shell 25 to form a limit. The limiting protrusions 30 on both sides of the socket shell 1 limit the position of the shielding shell 25 on the socket shell 1, so that the connection between the shielding shell 25 and the socket shell 1 is more stable, thereby preventing the shielding shell 25 from falling off during the use of the product and affecting the use of the product.
