Abstract
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] The RJ45 connector is a standard physical interface used in network communications (such as Ethernet) to enable wired data transmission between devices. In the electronic functional module of an RJ45 connector, there are typically at least two sets of coil assemblies within the internal cavity of the insulating housing, which work together to fulfill the functional requirements of the RJ45 connector (such as a network filter).
[0003] Since both sets of coil assemblies include multiple magnetic rings and stranded wires wound on the magnetic rings, the space occupied when laying out the two sets of coil assemblies is relatively large. This results in a larger internal cavity and overall size of the insulating mold, which increases the area occupied by the electronic functional module on the circuit board of the RJ45 connector, making it difficult to achieve miniaturization 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 the electronic functional module occupies a large area of the circuit board, which is not conducive to the miniaturization of the connector.
[0005] In a first aspect, embodiments of this application provide an electronic functional module, including: An insulating mold shell has a receiving cavity in its upper part and a relief groove in its lower part. The coil assembly is disposed inside the receiving cavity; The choke assembly is electrically connected to the coil assembly and is positioned in a clearance slot.
[0006] Optionally, the clearance groove includes a first clearance groove and a second clearance groove. The first clearance groove is located below the receiving cavity, and the second clearance groove is provided on one or both sides of the lower part of the insulating mold shell. The choke assembly is disposed in the first clearance groove or the second clearance groove.
[0007] Optionally, the receiving cavity, the first relief groove, and the second relief groove are all provided to extend along the length direction of the insulating mold shell.
[0008] Optionally, the end faces at both ends of the insulating mold shell along its length are respectively provided with a first slot and a second slot, wherein the projected area of the first slot along the length of the insulating mold shell is smaller than the projected area of the second slot along the length of the insulating mold shell.
[0009] Optionally, the electronic functional module also includes multiple terminals, which are respectively mounted on both sides of the insulating housing, and the coil assembly is electrically connected to the multiple terminals.
[0010] Optionally, the insulating housing includes two oppositely arranged sidewalls, and multiple mounting grooves extending vertically are provided on the sidewalls, with terminals installed in the mounting grooves.
[0011] Optionally, the top of the side wall is also provided with multiple wire grooves, which are connected to multiple mounting grooves one by one.
[0012] Optionally, the trough includes a guide surface that extends obliquely to the inner wall of the receiving cavity.
[0013] 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 electronic functional module is disposed on the circuit board, and the circuit board is also provided with electronic components, at least partially disposed in a recessed groove.
[0014] Optionally, the bottom of the insulating housing is provided with a downwardly protruding support portion, which abuts against the upper surface of the circuit board.
[0015] Optionally, the electronic functional module includes multiple terminals, which are respectively installed on both sides of the insulating housing, and the coil assembly is electrically connected to the circuit board through the multiple terminals.
[0016] Optionally, the choke assembly is mounted on a circuit board, and the choke assembly is electrically connected to the coil assembly via the circuit board.
[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 uses a combination of a coil assembly and a choke assembly to achieve filtering, instead of the traditional method of using two sets of coil assemblies to achieve filtering. Since the choke assembly is a small electronic component, the space required for its placement is less than that required for a conventional set of coil assemblies. As a result, the total volume of the coil assembly and the choke assembly in this application is smaller than the total volume of two sets of coil assemblies in a traditional electronic functional module.
[0018] In addition, this application only requires a set of coil assemblies to be placed in the receiving cavity of the insulating mold, while the choke assembly can be placed in the relief groove at the bottom of the insulating mold, which can reduce the volume of the receiving cavity and thus reduce the area occupied by the insulating mold on the circuit board. When the choke assembly and the insulating mold are placed on the circuit board, since the bottom of the insulating mold has a relief groove that matches the choke assembly, the area occupied by the insulating mold and the choke assembly on the circuit board can be completely or partially overlapped, which can reduce the overall area occupied by the electronic functional module on the circuit board and facilitate the miniaturization of the connector.
[0019] The connector provided in this application includes the above-mentioned electronic functional module. It can avoid the choke coil assembly and electronic components through the first and second clearance grooves provided at the lower part of the insulating mold shell. Therefore, it naturally has the technical effects of the above-mentioned electronic functional module. Attached Figure Description

[0022] 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.
[0023] 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.
[0024] 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.
[0025] To address the technical problem in existing technologies where electronic functional modules occupy a large area on the circuit board, hindering connector miniaturization, this application provides an electronic functional module and connector. This electronic functional module replaces a set of coil assemblies with a choke coil assembly 3. Only one set of coil assemblies 2 needs to be placed in the receiving cavity 11 of the insulating housing 1, while the choke coil assembly 3 can be placed in a clearance groove at the bottom of the insulating housing 1, reducing the volume of the receiving cavity 11 and thus reducing the area occupied by the insulating housing 1 on the circuit board 5. When the choke coil assembly 3 and the insulating housing 1 are arranged on the circuit board 5, the clearance groove at the bottom of the insulating housing 1, which matches the choke coil assembly 3, allows for complete or partial overlap of the areas occupied by the insulating housing 1 and the choke coil assembly 3 on the circuit board 5. This reduces the overall area occupied by the electronic functional module on the circuit board 5, facilitating connector miniaturization.
[0026] Please see Figures 1 to 10 The first aspect of this application provides an electronic functional module, including an insulating housing 1, a coil assembly 2, and a choke assembly 3. The insulating housing 1 is used to install and protect other components in the electronic functional module. The coil assembly 2 includes multiple magnetic rings 21 and stranded wires 22 wound on the magnetic rings 21, which can filter electrical signals. The choke assembly 3 can be used to replace another set of coil assemblies in a conventional electronic functional module to achieve filtering function. Since the choke assembly 3 is arranged in the form of a small electronic component, the space occupied by the arrangement is less than that required by a conventional set of coil assemblies, so that the total volume of the coil assembly 2 and the choke assembly 3 in this application is smaller than the total volume of the two sets of coil assemblies in a conventional electronic functional module.
[0027] The upper part of the insulating housing 1 has a receiving cavity 11 for accommodating and protecting the coil assembly 2, such as... Figure 1 and Figure 3 As shown. The lower part of the insulating mold shell 1 is provided with a relief groove, which includes a first relief groove 12 and a second relief groove 13. The first relief groove 12 is located below the receiving cavity 11, and the second relief groove 13 is provided on one or both sides of the lower part of the insulating mold shell 1, as shown. Figure 4 and Figure 5 As shown, multiple accommodating spaces can be formed at the bottom of the insulating mold shell 1. When the bottom of the insulating mold shell 1 is connected to the circuit board 5, other components can still be arranged below the first clearance groove 12 and the second clearance groove 13, so as to achieve a compact arrangement of the insulating mold shell 1 and various electronic components on the circuit board 5.
[0028] The coil assembly 2 is located inside the receiving cavity 11. Compared with traditional electronic functional modules, since the receiving cavity 11 only needs to accommodate one set of coil assembly 2, the volume of the receiving cavity 11 can be greatly reduced, thereby reducing the projected area of the receiving cavity 11 and the insulating mold shell 1 on the circuit board 5, which can greatly reduce the area occupied by the electronic functional module on the circuit board 5.
[0029] The choke coil assembly 3 is electrically connected to the coil assembly 2, forming a key magnetic component in the electronic functional module. Together, they can filter electrical signals. The choke coil assembly 3 is disposed in the first clearance slot 12 or the second clearance slot 13, such as... Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, the projected areas of the choke assembly 3 and the insulating housing 1 on the circuit board 5 can be completely or partially overlapped, thereby reducing the overall area occupied by the electronic functional module on the circuit board 5 and facilitating the miniaturization of the connector.
[0030] It should be noted that, since the choke component 3 in the existing technology is usually integrated in the form of a surface mount inductor, it is small in size and can be directly mounted on the circuit board 5 through surface mount technology (SMT) without the need for wire winding and soldering processes, which is conducive to achieving automated production.
[0031] The coil assembly 2 and the choke assembly 3 are respectively located at the upper and lower parts of the insulating mold shell 1, enabling a three-dimensional layered design, such as... Figure 9 As shown, this helps to reduce the overall area occupied by the electronic functional module on the circuit board 5.
[0032] In some embodiments of this application, please refer to Figure 4 , Figure 8 and Figure 9 The second clearance groove 13 includes a first groove wall 131 and a second groove wall 132 connected at an angle. The first groove wall 131 is concave upwards to allow for clearance in the height direction, and the second groove wall 132 is concave horizontally towards the interior of the insulating mold shell 1 to allow for clearance in the horizontal direction. When the choke assembly 3 or other electronic components are arranged in the second clearance groove 13, the choke assembly 3 or other electronic components can be brought as close as possible to the center of the insulating mold shell 1, thereby achieving a compact arrangement of multiple components on the circuit board 5, which helps to reduce the area of the circuit board 5.
[0033] It should be noted that the included angle between the first groove wall 131 and the second groove wall 132 is preferably a right angle or an obtuse angle, which can form a larger opening on the side of the second relief groove 13 facing away from the insulating mold shell 1, making it easier to install the choke coil assembly 3 or other electronic components into the second relief groove 13.
[0034] As a specific embodiment of this application, please refer to Figure 4 , Figure 8 and Figure 9 The first groove wall 131 is set horizontally, and the second groove wall 132 is set vertically. The included angle between the first groove wall 131 and the second groove wall 132 is a right angle, which facilitates the processing of the second relief groove 13. For example, when the insulating mold shell 1 is manufactured by injection molding, it is easy to demold.
[0035] Please refer to some preferred embodiments of this application. Figure 4 and Figure 5 The lower two sides of the insulating mold shell 1 are provided with second clearance grooves 13, so that electronic components can be compactly arranged on both sides of the insulating mold shell 1. When the lower part of the insulating mold shell 1 is connected to the circuit board 5, the area occupied by the lower part of the insulating mold shell 1 on the circuit board 5 can be reduced to the greatest extent.
[0036] In some embodiments of this application, please refer to Figure 3 , Figure 4 and Figure 5 The receiving cavity 11, the first clearance groove 12, and the second clearance groove 13 are all extended along the length direction of the insulating mold shell 1. This can make full use of the space along the length direction of the insulating mold shell 1, so that the receiving cavity 11 can arrange multiple magnetic rings 21 in the coil assembly 2 in sequence along the length direction of the insulating shell. The choke coil assembly 3 set in the first clearance groove 12 or the second clearance groove 13 can also be adapted and connected to the wiring of the coil assembly 2, which helps to reduce the complexity and chaos of the layout and improve the rationality and operability of the design.
[0037] When manufacturing the insulating mold shell 1, the receiving cavity 11, the first relief groove 12, and the second relief groove 13, which extend in the same direction, are easier to standardize and scale up during processing. For example, when injection molding the insulating mold shell 1, the design and manufacturing of the mold can be simpler, and the process parameters during molding are easier to control, which helps to reduce manufacturing costs and improve production efficiency.
[0038] In some embodiments of this application, please refer to Figures 3 to 5 The end faces of the two ends of the insulating mold shell 1 along the length direction are respectively provided with a first slot 14 and a second slot 15. The projected area of the first slot 14 along the length direction of the insulating mold shell 1 is smaller than the projected area of the second slot 15 along the length direction of the insulating mold shell 1. This can realize the differentiated design of the two ends of the insulating mold shell 1, which facilitates the realization of mistake-proof assembly during the assembly process.
[0039] Specifically, the first slot 14 and the second slot 15 can be used to engage with the assembly fixture, so that the insulating mold 1 can only engage with the fixture in a single accurate position, and then the fixture is used to assemble the insulating mold 1 with the circuit board 5.
[0040] It should be noted that the first slot 14 and the second slot 15 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 14 and the second slot 15, thereby improving the accuracy and efficiency of operation.
[0041] As a specific embodiment of this application, please refer to Figure 4 and Figure 5 The width of the first slot 14 is smaller than the width of the second slot 15, so that the projected area of the second slot 15 along the length of the insulating mold 1 is larger than the projected area of the first slot 14 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 14 and the second slot 15.
[0042] In some embodiments of this application, please refer to Figure 2 , Figure 6 , Figure 8 and Figure 9 The electronic functional module also includes multiple terminals 4, which are respectively installed on both sides of the insulating housing 1, and the coil assembly 2 is electrically connected to the multiple terminals 4 so as to achieve electrical connection with the circuit board 5 and the choke assembly 3 through the multiple terminals 4.
[0043] It should be noted that since multiple terminals 4 are respectively installed on both sides of the insulating housing 1, a variety of interface options are provided for the electrical connection between the coil assembly 2 and the circuit board 5 and the choke assembly 3. This facilitates the connection of multiple cables 221 of the twisted wire 22 in the coil assembly 2 to the terminals 4 on both sides of the insulating housing 1 through the receiving cavity 11. This can shorten the routing length of the cables 221 and avoid long-distance winding of the cables 221 inside or outside the insulating housing 1. This not only reduces the amount of cables 221 used and lowers the material cost, but also effectively reduces the resistance and inductance of the cables 221, and reduces signal loss and interference during transmission.
[0044] In some embodiments of this application, please refer to Figure 8 and Figure 9The insulating housing 1 includes two opposing side walls 16, and multiple mounting grooves 17 extending vertically are provided on the side walls 16. The terminal 4 is installed in the mounting groove 17, which provides a precise installation position and a stable fixing structure for the terminal 4, ensuring the positional accuracy of the terminal 4 during the use of the electronic functional module and avoiding poor contact problems caused by loose terminal 4.
[0045] Meanwhile, mounting slots 17 are vertically formed on the side wall 16 of the insulating housing 1, making full use of the vertical space of the relatively small side wall 16 of the insulating housing 1 and improving space utilization. Mounting slots 17 are formed on both opposite side walls 16 to install terminals 4, making the distribution of terminals 4 more symmetrical and orderly. This helps optimize the overall layout of the entire electronic functional module or circuit board 5, making electrical connections more regular, reducing the crossing and tangling of cables 221, and improving the reliability and maintainability of the circuit.
[0046] In some embodiments of this application, please refer to Figure 6 The coil assembly 2 includes four magnetic rings 21, each magnetic ring 21 is wound with a stranded wire 22, and the stranded wire 22 wound on each magnetic ring 21 is respectively connected to the three terminals 4 on the left and the three terminals 4 on the right to realize the filtering function of the coil assembly 2.
[0047] In some embodiments of this application, please refer to Figure 3 , Figure 6 and Figure 7 The top of the side wall 16 is also provided with multiple wire grooves 18, which are connected to multiple mounting grooves 17 one by one. They can be used to fix multiple cables 221 that are split and extended from the twisted wire 22, so that the multiple cables 221 are arranged in a preset position to prevent the cables 221 from getting tangled or crossing each other.
[0048] The connection between the cable tray 18 and the mounting slot 17 provides intuitive positioning guidance for welding the cable 221 to the top of the terminal 4. This facilitates the positioning and welding of the cable 221 to the top of the terminal 4. During welding, operators can accurately guide the cable 221 to the corresponding top of the terminal 4 along the cable tray 18, eliminating the need for extensive searching and alignment of the cable 221. This intuitive positioning method greatly improves welding accuracy and reduces welding defects caused by inaccurate positioning, such as cold solder joints and mis-soldering.
[0049] At the same time, during the welding process, the cable tray 18 effectively restrains the cable 221, preventing the cable 221 from loosening or shifting due to vibration, external pulling, or other reasons, which is conducive to achieving precise welding through automated welding equipment.
[0050] It should be noted that one or more cables 221 can be installed in the cable tray 18, such as... Figure 6 As shown, the corresponding arrangement between cable 221 and cable tray 18 is determined according to the specific wiring scheme.
[0051] In some embodiments of this application, please refer to Figure 9 and Figure 10 The cable tray 18 includes a guide surface 181 that extends obliquely to the inner wall of the receiving cavity 11. When the cable 221 extends from the receiving cavity 11 into the cable tray 18, it can make surface contact with the guide surface 181, thereby increasing the contact area between the cable 221 and the cable tray 18 and preventing the cable 221 from only contacting the sharp edges of the cable tray 18 and causing wear.
[0052] In some embodiments of this application, please refer to Figure 7 and Figure 8 The cable trough 18 is also provided with limiting surfaces 182 and guide surfaces 183 on both sides. When the cable 221 is inserted into the cable trough 18, it can be guided by the inclined guide surfaces 183. Just bring the cable 221 close to the guide surfaces 183 and press it down. The cable 221 will slide naturally into the cable trough 18 between the two limiting surfaces 182 along the inclined direction of the guide surfaces 183. Thus, the two limiting surfaces 182 are used to clamp and position the cable 221.
[0053] Please see Figures 1 to 10 The second aspect of this application provides a connector, including the electronic functional module described in the above embodiments, and also including a circuit board 5. The circuit board 5 is provided with electronic components 6, and the electronic components 6 and the choke assembly 3 are respectively disposed in the first clearance groove 12 and the second clearance groove 13.
[0054] When the electronic functional module is set on the circuit board 5, the electronic components 6 installed on the circuit board 5 can be avoided by the first clearance slot 12 or the second clearance slot 13. The layout area of the circuit board 5 can be fully utilized to achieve a compact layout of various electronic components, reduce unnecessary space waste, make the overall connector smaller, and facilitate the miniaturization of the connector.
[0055] It should be noted that, in order to avoid interference between the choke assembly 3 and the electronic component 6 at the bottom of the insulating mold shell 1, when one of the choke assembly 3 and the electronic component 6 is set in the first clearance groove 12, the other is set in the second clearance groove 13. To avoid mutual interference and influence between them in space, the positions of the choke assembly 3 and the electronic component 6 can be interchanged, and no limitation is made here.
[0056] Please refer to some preferred embodiments of this application. Figure 1 , Figure 2 , Figure 8 and Figure 9 The choke assembly 3 is located in the first clearance groove 12, directly below the coil assembly 2, which facilitates electrical connection between the circuit board 5 and the terminals 4 on both sides of the coil assembly 2, thereby realizing the corresponding connection between the choke assembly 3 and the coil assembly 2; the electronic component 6 includes components such as resistors and capacitors, and the electronic component 6 is located in the second clearance groove 13, which can reduce the area occupied by the insulating mold shell 1 on the circuit board 5.
[0057] It should be noted that other electronic components can also be set on the side of the circuit board 5 facing away from the insulating mold 1 to achieve other functions. This can make full use of the layout area of the upper and lower surfaces of the circuit board 5, so that the volume of the circuit board 5 can be reduced as much as possible, thereby achieving the miniaturization of the connector.
[0058] In some embodiments of this application, please refer to Figure 4 , Figure 5 and Figure 9 The bottom of the insulating housing 1 is provided with a downwardly protruding support part 19, which abuts against the upper surface of the circuit board 5. This support part 19 can raise the lower opening of the first relief groove 12 upward, so that the heat inside the first relief groove 12 can be transferred along the... Figure 9 The dashed arrows radiate outwards to prevent heat from accumulating inside the first clearance groove 12, which could affect the working efficiency and lifespan of the electronic components inside the first clearance groove 12.
[0059] Specifically, the support part 19 can be a support plate or a support leg. Multiple support parts 19 are arranged sequentially along the circumference of the insulating mold shell 1 to support the insulating mold shell 1 and to make the lower opening of the first relief groove 12 have a preset distance from the upper surface of the circuit board 5, forming a certain air circulation space, promoting air convection, and facilitating the dissipation of heat inside the first relief groove 12. This helps to ensure that the temperature of the electronic components (such as the choke coil assembly 3 or electronic components 6) installed inside the first relief groove 12 is within the normal range, and avoids excessively high temperatures from affecting the working efficiency and service life of the electronic components.
[0060] In some embodiments of this application, please refer to Figure 2 and Figure 9 The electronic functional module includes multiple terminals 4. The coil assembly 2 is electrically connected to the circuit board 5 through multiple terminals 4. The circuit board 5 is provided with multiple connecting parts 51 for connecting to the multiple terminals 4 one by one. The connection method can be abutment, snap-fit or soldering, which is not limited here.
[0061] It should be noted that when multiple terminals 4 are symmetrically arranged on both sides of the insulating mold shell 1, the bottom ends of multiple terminals 4 on any side can be arranged in a single row, or the bottom ends of some terminals 4 can be bent to form an interlaced arrangement. There is no limitation here.
[0062] In some embodiments of this application, please refer to Figure 2 and Figure 9 The choke assembly 3 is mounted on the circuit board 5, and the choke assembly 3 is electrically connected to the coil assembly 2 through the circuit board 5 so that the choke assembly 3 and the coil assembly 2 can work together to achieve the filtering function.
[0063] Specifically, the electrical signal transmission path between coil assembly 2 and choke assembly 3 is: coil assembly 2—terminal 4—circuit board 5—choke assembly 3. The wiring design on circuit board 5 can effectively isolate interference between different signals. During the transmission of electrical signals from coil assembly 2 to choke assembly 3, circuit board 5 can separate the signal line from other lines that may cause interference, reducing the impact of electromagnetic interference (EMI) and radio frequency interference (RFI) on the signal, helping to maintain the integrity and stability of the electrical signal, and improving the reliability of the filtering function.
[0064] In some embodiments of this application, the connector is specifically an RJ45 connector. By cooperating with the coil assembly 2, the choke assembly 3 can effectively suppress high-frequency noise and common-mode interference, thereby realizing the filtering function of the RJ45 connector. Furthermore, the coil assembly 2 and the choke assembly 3 are designed in layers, which can ensure the communication function of the RJ45 connector while also enabling the miniaturization of the RJ45 connector.
[0065] In some embodiments of this application, please refer to Figures 1 to 10 The assembly process of the above connectors is as follows: Step 1: Insert multiple terminals 4 into the mounting slots 17 on both sides of the insulating mold shell 1 by automatic insertion and riveting. Place the coil assembly 2 into the receiving cavity 11 of the insulating mold shell 1, and place the cable 221 of the twisted wire 22 of the coil assembly 2 into the corresponding wire slot 18, so that the multiple cables 221 are correspondingly set with the welding ends on the top of the multiple terminals 4. The connection between the cable 221 and the terminal 4 is achieved by manual welding or automatic welding.
[0066] Step 2: Mount the choke coil assembly 3 on the upper surface of the circuit board 5, and place the electronic components 6 on the upper surface of the circuit board 5; Step 3: Assemble the insulating mold shell 1 onto the circuit board 5 using a fixture, so that multiple terminals 4 are connected to multiple connecting parts 51 on the circuit board 5, and at the same time, the choke coil assembly 3 and electronic components 6 on the upper surface of the circuit board 5 are respectively located in the first clearance groove 12 and the second clearance groove 13.
[0067] It should be noted that the order of steps one and two can be changed, or they can be performed simultaneously, both of which will achieve the purpose of this application. The structural design of this application facilitates the automated assembly of electronic functional modules and connectors, significantly reducing labor costs while improving assembly efficiency.
