Description

Technical Field

[0001] This application relates to the field of network communication and data transmission technology, and in particular to an electronic functional module and connector. Background Technology

[0002] With the trend of miniaturization in connectors, the size of the internal components of connectors is gradually shrinking, and the components are tightly connected, which puts forward higher requirements for the manufacturing yield and reliability of connectors.

[0003] For example, an RJ45 connector (a standard interface connector used for Ethernet) typically includes an electronic functional module and a circuit board for electrical connection. The electronic functional module includes multiple signal terminals for connecting to the circuit board. Since the multiple signal terminals are closely arranged in the same direction, the distance between the pins of two adjacent signal terminals is relatively close. When multiple pins are soldered to the circuit board, the excessively close pin spacing will cause the solder to flow unimpeded between the terminal pins, which can easily lead to solder bridging, resulting in short circuits or signal interference, affecting the manufacturing yield and reliability of the connector. Summary of the Invention

[0004] This application provides an electronic functional module and connector to solve the technical problem in the prior art where excessively dense terminal pins in electronic functional modules lead to solder bridging, affecting the processing yield and reliability of connectors.

[0005] In a first aspect, embodiments of this application provide an electronic functional module, including: An insulating mold shell, with multiple mounting grooves on its side walls; The terminal assembly includes a plurality of first terminals and a plurality of second terminals, which are alternately arranged in a plurality of mounting slots along the length of the sidewall; the first terminals have first pins, the second terminals have second pins, and the plurality of first pins and the plurality of second pins are alternately arranged.

[0006] Optionally, the insulating housing includes two oppositely arranged sidewalls, each sidewall being equipped with a terminal assembly, and the terminal assemblies installed on the two sidewalls are arranged in a centrally symmetrical manner.

[0009] Optionally, the groove has an upwardly inclined wall surface, the bottom end of which is connected at an angle to the inner wall surface of the mounting groove.

[0010] Optionally, the angle between the bottom end of the inclined wall and the inner wall of the mounting groove is the first included angle; The first terminal also includes a first main body segment extending in a vertical direction. The first main body segment is disposed in the mounting groove. The bent segment is connected to the first main body segment at an angle, and the included angle between the bent segment and the first main body segment is a second included angle, and the second included angle is greater than or equal to the first included angle.

[0011] Optionally, the insulating housing and terminal assembly are integrally formed.

[0013] Optionally, the upper part of the insulating mold shell is provided with a receiving cavity, and the coil assembly is disposed in the receiving cavity; The insulating housing has upwardly extending protective sections at both ends, which protrude from the coil assembly.

[0014] Optionally, the lower part of the insulating mold shell is provided with a relief groove.

[0015] Secondly, embodiments of this application provide a connector, including the electronic functional module provided in the first aspect of embodiments of this application, and also including a circuit board. The circuit board includes a communication area corresponding to the sidewall, and the communication area is provided with a plurality of connecting parts, which are staggered along the length direction of the sidewall.

[0016] Optionally, the bottom of the insulating mold shell has a first positioning part, and the circuit board has a second positioning part that matches the first positioning part.

[0017] The technical solutions provided in this application have the following advantages compared with the prior art: The electronic functional module provided in this application includes a plurality of first terminals and a plurality of second terminals alternately spaced along the length of the sidewall of the insulating housing. This allows for a tight arrangement of the multiple first terminals and the multiple second terminals along the length of the sidewall. The first pins of the first terminals and the second pins of the second terminals are alternately arranged to form a "W" shape. While maintaining the spacing between the first terminals and the second terminals along the length of the sidewall, the spacing between the pins of adjacent first terminals and second terminals can be extended. This not only achieves a compact arrangement of multiple terminals on the insulating housing, but also avoids solder bridging during the soldering connection with the circuit board due to excessively dense pin spacing, thus improving soldering quality and product reliability.

[0018] The connector provided in this application includes the above-mentioned electronic functional module. It can avoid solder bridging between the pins and the circuit board during the soldering process by using multiple staggered pins, thereby avoiding short circuits or signal interference.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0026] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0027] To address the technical problem in existing electronic functional modules where excessively dense terminal pins lead to solder bridging, affecting the processing yield and reliability of connectors, this application provides an electronic functional module and connector. The terminal assembly 2 in the electronic functional module includes multiple first terminals 21 and multiple second terminals 22, which are alternately spaced along the length of the side wall 11 of the insulating housing 1. The first pin 211 of the first terminal 21 and the second pin 221 of the second terminal 22 are staggered, which can maximize the pin spacing between two adjacent terminals (and the first terminal 21 and the second terminal 22), thereby avoiding solder bridging when the electronic functional module is soldered to the circuit board 4, and thus improving the processing yield and reliability of the connector.

[0028] Please see Figures 1 to 13 The first aspect of this application provides an electronic functional module, including an insulating housing 1 and a terminal assembly 2. The insulating housing 1 is used for mounting and protecting other components in the electronic functional module, and the terminal assembly 2 is used for electrical connection with a circuit board 4 in a connector, such as... Figure 1 , Figure 2 and Figure 3As shown.

[0029] Multiple mounting slots 12 are provided on the side wall 11 of the insulating housing 1 for mounting the terminal assembly 2, thereby fixing and positioning the terminal assembly 2. This ensures that the terminal assembly 2 is installed in a preset position, eliminating random errors from manual assembly and facilitating accurate assembly, positioning, and connection between the terminal assembly 2 and the circuit board 4. Figure 5 , Figure 7 and Figure 8 As shown.

[0030] Terminal assembly 2 includes a plurality of first terminals 21 and a plurality of second terminals 22, which are alternately spaced in a plurality of mounting slots 12 along the length of the sidewall 11, such as... Figure 3 and Figure 4 As shown, multiple first terminals 21 and multiple second terminals 22 can be closely arranged in the length direction of the side wall 11, which is beneficial to the miniaturization of the insulating mold shell 1 and the connector.

[0031] The first terminal 21 has a first pin 211, and the second terminal 22 has a second pin 221. Multiple first pins 211 and multiple second pins 221 are arranged alternately (i.e., the first pins 211 and second pins 221 are alternately distributed on both sides of the sidewall 11 in the width direction), forming a "W" shape arrangement. Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 11 and Figure 13 As shown. Without changing the spacing between the first terminal 21 and the second terminal 22 along the length of the side wall 11, the pin spacing between adjacent first terminals 21 and second terminals 22 can be extended. This allows for a compact arrangement of multiple terminals on the insulating housing 1 and avoids solder bridging during the soldering process with the circuit board 4 due to excessively close pin spacing.

[0032] It should be noted that this application staggers the pins of adjacent first terminals 21 and second terminals 22, thereby extending the pin spacing between adjacent first terminals 21 and second terminals 22 without changing the distance between them along the length of the side wall 11. This achieves a compact arrangement of multiple terminals on the insulating housing 1, saving space, and effectively avoids solder bridging during the soldering process with the circuit board 4 due to excessively close pin spacing, thus improving soldering quality and product reliability.

[0033] In some embodiments of this application, please refer to Figure 3 , Figure 6 and Figure 11The insulating mold shell 1 includes two opposing sidewalls 11, each of which is equipped with a terminal assembly 2. This allows multiple terminals to be distributed on both sides of the insulating mold shell 1, which helps to shorten the length of the insulating mold shell 1. The terminal assemblies 2 installed on the two sidewalls 11 are centrally symmetrical (i.e., they overlap after rotating 180 degrees). During the injection molding manufacturing of the insulating mold shell 1, only one mold core corresponding to the terminal assembly 2 needs to be made to prepare the mounting grooves 12 on both sides of the insulating mold shell 1, thereby realizing the installation of the terminal assemblies 2 on both sides of the insulating mold shell 1. This helps to reduce mold development costs and the manufacturing costs of electronic functional modules.

[0034] In some embodiments of this application, please refer to Figure 4 , Figure 6 , Figure 8 and Figure 13 The first terminal 21 includes a bent section 212, which extends along the width direction of the side wall 11. The first pin 211 is connected to the bent section 212, so that the first pin 211 is misaligned with the second pin 221 of the second terminal 22 in the width direction of the side wall 11, thereby increasing the distance between the first pin 211 and the adjacent second pin 221. While maintaining the compact arrangement of the terminals (such as the distance between the first terminal 21 and the second terminal 22 in the length direction of the side wall 11 remains unchanged), the pin spacing is expanded by the misalignment in the width direction, so that the solder can fully climb to the root of the pin, forming a reliable solder joint and reducing the risk of solder bridging.

[0035] In some embodiments of this application, please refer to Figure 4 The first terminal 21 includes a first main body segment 213, a bent segment 212 and a first pin 211 that are connected in a stepped shape, while the second terminal 22 includes a second main body segment 222 and a second pin 221 that are connected in a straight line. The first pin 211 is connected to the end of the bent segment 212 away from the second terminal 22, which can maximize the distance between the first pin 211 and the second pin 221.

[0036] It should be noted that in the above embodiments, multiple first terminals 21 and multiple second terminals 22 can be inserted into the insulating mold shell 1 first, and then the first terminals 21 can be bent to achieve the staggered arrangement of the first pins 211 and the second pins 221; alternatively, the first terminals 21 can be bent first, and then the multiple first terminals 21 and multiple second terminals 22 can be integrally injection molded with the insulating mold shell 1, both of which can achieve the purpose of this application.

[0037] In some embodiments of this application, please refer to Figures 5 to 9The bottom of the insulating mold shell 1 is provided with multiple upwardly recessed grooves 13, which extend along the width direction of the side wall 11. Each groove 13 corresponds to a different mounting slot 12 containing the first terminal 21, and the grooves 13 extend directly to the bottom of the mounting slot 12, without requiring additional space in the thickness direction of the insulating mold shell 1. After the first terminal 21 is inserted into the mounting slot 12, the upwardly recessed grooves 13 provide positioning support for the bending of the bent section 212, ensuring the accuracy of the bending operation. Furthermore, since the bent section 212 is located within the grooves 13, the grooves 13 can limit the bending of the bent section 212, preventing the first terminal 21 from detaching from the mounting slot 12.

[0038] In some embodiments of this application, please refer to Figure 8 and Figure 9 The groove 13 has an upwardly inclined wall surface 131. The bottom end of the inclined wall surface 131 is connected at an angle to the inner wall surface of the mounting groove 12. This allows the first terminal 21 to be bent along the connection between the mounting groove 12 and the inclined wall surface 131 after it is inserted into the mounting groove 12, forming a bent section 212. The inclined wall surface 131 forms a specific angle with the inner wall surface of the mounting groove 12. During the bending process, the bent section 212 fits against the inclined wall surface 131, which can limit the degree of bending of the bent section 212 and support the bent section 212, reducing the risk of the first terminal 21 breaking.

[0039] In some embodiments of this application, please refer to Figure 4 and Figure 9 The angle between the bottom end of the inclined wall 131 and the inner wall of the mounting groove 12 is the first included angle α. The first terminal 21 also includes a first main body section 213 extending in the vertical direction. The first main body section 213 is disposed in the mounting groove 12. The bent section 212 is connected to the first main body section 213 at an angle, and the angle between the bent section 212 and the first main body section 213 is the second included angle β. The second included angle β ≥ the first included angle α. Since the metal terminal has elasticity after bending, and the first included angle α determines the bending angle of the bent section 212 bending upward, when the second included angle β ≥ the first included angle α, the bending degree of the bent section 212 can be increased, so that the design angle (i.e. β) requirement is met after its rebound.

[0040] Specifically, the two ends of the bent section 212 are perpendicularly connected to the first main body section 213 and the first pin 211 respectively (i.e., β is 90 degrees), which can ensure that the first pin 211 extends in the vertical direction and remains parallel to the second pin 221, avoiding changes in the distance between the first pin 211 and the adjacent second pin 221 caused by the tilting of the first pin 211.

[0041] It should be noted that, in the above embodiments, multiple first terminals 21 and multiple second terminals 22 can be inserted into the mounting slots 12 on both sides of the insulating mold shell 1 by an automatic insertion device, and then the multiple first terminals 21 can be bent by a bending machine, thereby realizing the staggered arrangement of the first pins 211 and the second pins 221.

[0042] In other embodiments of this application, please refer to Figures 10 to 13 The insulating mold shell 1 and the terminal assembly 2 are integrally molded. Specifically, multiple second terminals 22 and multiple bent first terminals 21 are integrally injection molded with the insulating mold shell 1. The installation of multiple first terminals 21 and multiple second terminals 22 does not need to be achieved through automatic insertion equipment, which can simplify the production process and improve production efficiency.

[0043] Meanwhile, the bottom of the insulating mold shell 1 does not need to have a groove 13, which simplifies the injection mold structure of the insulating mold shell 1. The mold core corresponding to the terminal assembly 2 does not need to be set inside the mold of the insulating mold shell 1. The mounting grooves 12 on both sides of the insulating mold shell 1 (i.e., the first mounting groove 12a and the second mounting groove 12b) can be directly formed by injection molding, which helps to reduce mold cost and production cost.

[0044] In some embodiments of this application, please refer to Figure 1 , Figure 3 and Figure 7 The electronic functional module also includes a magnetic component 3, which is electrically connected to the terminal component 2. The magnetic component 3 can realize the filtering function of the electronic functional module, filter out high-frequency interference signals, and reduce data transmission errors and loss.

[0045] In some embodiments of this application, please refer to Figure 1 , Figure 3 and Figure 7 The magnetic component 3 includes two electrically connected coil assemblies, referred to as the first coil assembly 31 and the second coil assembly 32, respectively. The filtering function of the electronic functional module can be realized through the cooperation of the two coil assemblies. The connection method between the first coil assembly 31 and the second coil assembly 32 can refer to the prior art and is not limited here.

[0046] In other embodiments of this application, the magnetic component 3 includes an electrically connected coil assembly and a choke assembly. The filtering function of the electronic functional module can be achieved through the cooperation of a set of coil assemblies and choke assemblies. Since the choke assembly can be directly mounted on the circuit board 4 in a surface mount manner, and the coil assembly is disposed in the electronic functional module, the electrical connection between the coil assembly and the choke assembly can be achieved through the terminal assembly 2 and the circuit board 4.

[0047] In some embodiments of this application, please refer to Figure 7 , Figure 8 and Figure 13 The upper part of the insulating housing 1 has a receiving cavity 14, in which the coil assembly is disposed, which can realize the surrounding protection of the coil assembly. The top of the side wall 11 has multiple wire grooves 18, which can be used to fix the cable in the coil assembly, so as to facilitate the connection of the cable to the first terminal 21 or the second terminal 22.

[0048] For details, please refer to Figure 4 The top of the first terminal 21 is provided with a first connecting section 214, and the top of the second terminal 22 is provided with a second connecting section 223, both of which can be used to weld to the cable of the coil assembly.

[0049] The insulating housing 1 has upwardly extending protective portions 15 at both ends along its length. The protective portions 15 protrude from the coil assembly to prevent the upper part of the coil assembly from being scratched. Specifically, the top of the insulating housing 1 is usually provided with a cover plate to close the receiving cavity 14. The top of the protective portion 15 protrudes from the coil assembly to prevent the coil assembly from being scratched by the cover plate due to its excessive height.

[0050] In some embodiments of this application, please refer to Figure 5 and Figure 10 The sidewalls 11 are located at both ends in the width direction of the insulating mold shell 1, and the protective parts 15 are located at both ends in the length direction of the insulating mold shell 1. The sidewalls 11 and the protective parts 15 enclose and form a receiving cavity 14. The height of the protective parts 15 can be flush with the height of the sidewalls 11 or it can protrude from the top of the sidewalls 11. As long as the coil assembly can be prevented from being scratched, the purpose of this application can be achieved. No limitation is made here.

[0051] In some embodiments of this application, please refer to Figure 5 , Figure 10 and Figure 12 In order to facilitate the foolproof assembly of the insulating mold shell 1, the protective parts 15 at both ends of the insulating mold shell 1 are designed differently, and are respectively referred to as the first protective part 15a and the second protective part 15b. Specifically, the first protective part 15a and the second protective part 15b can be set to different shapes and sizes, or a foolproof structure can be set on one of the protective parts 15, etc., which can achieve the purpose of this application.

[0052] As a specific embodiment of this application, a mis-proof groove 151 is provided in the middle of the first protective part 15a, such as... Figure 5 and Figure 10 As shown, the front end of the insulating mold 1 is marked, allowing operators to intuitively and quickly confirm the assembly direction of the insulating mold 1 during assembly.

[0053] In some embodiments of this application, please refer to Figure 1 , Figure 3 , Figure 10 and Figure 12 The end faces of the front and rear ends of the insulating mold 1 are also provided with slots 19, which can be used to cooperate with the fixture to realize the assembly between the insulating mold 1 and the circuit board 4.

[0054] In some embodiments of this application, please refer to Figure 1 , Figure 3 , Figure 10 and Figure 12 The end faces of the two ends of the insulating mold shell 1 along the length direction are respectively provided with a first slot 19a and a second slot 19b. The projected area of ​​the first slot 19a along the length direction of the insulating mold shell 1 is smaller than the projected area of ​​the second slot 19b along the length direction of the insulating mold shell 1. This can also realize the differentiated design of the two ends of the insulating mold shell 1, which is convenient for mistake-proof assembly during the assembly process.

[0055] It should be noted that the first slot 19a and the second slot 19b have different shapes and / or sizes, which can intuitively distinguish the two ends of the insulating mold shell 1. During production, assembly and maintenance, operators can quickly identify the different ends of the insulating mold shell 1 and accurately determine whether the installation direction of each insulating mold shell 1 is accurate based on the shape and / or size characteristics of the first slot 19a and the second slot 19b, thus improving the accuracy and efficiency of operation.

[0056] As a specific embodiment of this application, please refer to Figure 10 and Figure 12 The width of the first slot 19a is smaller than the width of the second slot 19b, so that the projected area of ​​the second slot 19b along the length of the insulating mold 1 is larger than the projected area of ​​the first slot 19a along the length of the insulating mold 1. The operator can distinguish the front end and the rear end of the insulating mold 1 by observing the dimensions of the first slot 19a and the second slot 19b.

[0057] It should be noted that, in the above embodiments, the anti-foolproof design of the anti-foolproof groove 151 and the card slot 19 can be selectively provided on the insulating mold shell 1, or both can be provided on the insulating mold shell 1, both of which can achieve the purpose of this application, and no limitation is made here.

[0058] In some embodiments of this application, please refer to Figure 3 and Figure 13 The lower part of the insulating housing 1 is provided with a clearance groove 16. When the electronic functional module is assembled on the circuit board 4, it can avoid the electronic components 5 arranged on the circuit board 4, which is conducive to the compact arrangement of various electronic components on the circuit board 4.

[0059] In some embodiments of this application, the clearance groove 16 may be disposed at the lower center and / or lower sides of the insulating housing 1 to partition and avoid electronic components 5 (such as the first electronic component 5a, the second electronic component 5b, and the third electronic component 5c) in different areas of the circuit board 4. Specifically, the electronic components 5 may be resistors, capacitors, surge suppression thyristors (TSS components), and transient voltage suppression diodes (TVS components), etc. When the magnetic assembly 3 includes a choke assembly, the clearance groove 16 may also be used to avoid the choke assembly mounted on the circuit board 4.

[0060] It should be noted that the clearance groove 16 not only allows for the avoidance of electronic components 5 or choke assemblies on the circuit board 4, but also reduces the amount of glue used during the injection molding of the insulating mold shell 1, making it easier to achieve the injection molding of the insulating mold shell 1.

[0061] Please see Figures 1 to 13 The second aspect of this application provides a connector, including the electronic functional module described in the above embodiments, and also includes a circuit board 4. The circuit board 4 includes a communication area corresponding to the side wall 11. The communication area is provided with a plurality of connecting parts 41. The plurality of connecting parts 41 are staggered along the length direction of the side wall 11 so that the staggered plurality of first pins 211 and a plurality of second pins 221 can be connected accordingly.

[0062] Specifically, after the first pin 211 and the second pin 221 are inserted into their corresponding connecting parts 41, the electrical connection between the pins and the circuit board 4 is achieved by soldering. Since the spacing between two adjacent pins is large, solder bridging can be avoided during the soldering process, thereby avoiding short circuits or signal interference, which helps to ensure the processing yield and reliability of the connector.

[0063] In some embodiments of this application, the connector is specifically an RJ45 connector. By interleaving multiple first pins 211 and multiple second pins 221, the reliability of the connection between the electronic functional module in the RJ45 connector and the circuit board 4 can be ensured, thereby ensuring that the signal of the RJ45 connector is transmitted according to the design path, reducing data transmission errors and packet loss, and improving the accuracy and stability of data transmission.

[0064] In some embodiments of this application, please refer to Figure 2 , Figure 3 , Figure 5 , Figure 10 and Figure 12 The bottom of the insulating mold 1 has a first positioning part 17, and the circuit board 4 has a second positioning part 42 that matches the first positioning part 17, which facilitates the assembly between the insulating mold 1 and the circuit board 4, thereby improving the assembly efficiency of the connector.

[0065] In some embodiments of this application, the first positioning part 17 is disposed on one side of the insulating mold shell 1, such as... Figure 5 and Figure 6 As shown, or, the first positioning part 17 is disposed at one corner of the insulating mold shell 1, such as... Figure 10 and Figure 12 As shown, the insulating housing 1 can only achieve the cooperation between the first positioning part 17 and the second positioning part 42 in a single assembly position, which can realize foolproof assembly and avoid the electronic functional module being reversed and affecting its function.
