[0001] The embodiments of the present application relate to the technical field of electrical connectors, and in particular to a connector assembly, an electronic device, and a manufacturing method of the connector assembly. Background Art
[0002] A coaxial cable is a cable with a multi-layer coaxial structure from the inside to the outside, and generally includes a conductor, a shielding layer, and a first insulating layer (or called a sheath) sequentially arranged from the inside to the outside. This structure enables the coaxial cable to effectively resist electromagnetic interference during signal transmission, thereby ensuring the stability and integrity of the signal. A connector usually has conductive terminals electrically connected to the cable.
[0003] Currently, in fields such as drones, high-definition cameras, and in-vehicle display systems, a component assembled by a connector and multiple coaxial cables is required, and the communication precision requirement is very high.

Specifically, a copper bar with grounding spikes is used, and the grounding spikes of the copper bar pierce the first insulating layer of each coaxial cable, so that the grounding spikes are connected to the shielding layer of the coaxial cable, and then the copper bar is connected to the shielding housing to implement this solution. Subsequently, the inventors further found that although the electromagnetic interference prevention effect is improved in this way, the shielding effect still fails to meet the expectation, and the signal transmission does not obtain an ideal effect. Through multiple detections, comparisons, and discussions, it is finally found that during the process of the grounding spikes piercing the first insulating layer and penetrating into the coaxial cable, the piercing force and angle of the grounding spikes are difficult to accurately control, which easily causes damage to the shielding layer, deformation or position deviation of the pierced copper bar, and further leads to a poor connection effect between the grounding spikes and the cable.

The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.
[0044] In the related art, components assembled by a connector and multiple coaxial cables are widely used in fields such as unmanned aerial vehicles, high-definition cameras, and in-vehicle display systems. The communication precision requirements of the connector components are very high. Therefore, there is a high demand for electromagnetic interference prevention at the connection between the conductive terminals and the coaxial cable. How to improve the electromagnetic interference prevention here is an urgent problem to be solved in the industry.
[0045] In view of this, the inventor found during the research and development process that a shielding housing can be provided in the connector, and the shielding housing is connected to the shielding layer of the coaxial cable to provide a continuous shielding path, which plays a role in preventing electromagnetic interference for the conductive terminals and the cable connection part located in the receiving cavity.
[0046] The embodiment of the present application provides a connector assembly 1000 and a manufacturing method of the connector assembly 1000, which is beneficial to improving the shielding connection reliability between the cable and the connector and enhancing the shielding effect.
[0047] Please refer to Figure 1 , the connector assembly 1000 includes a connector 1, a cable 2, and a first shielding member 3. The cable 2 is electrically connected to the connector 1, and the first shielding member 3 is used to shield-connect the cable 2 and the connector 1.
[0048] Shielding connection means establishing an electrical connection between the shielding structures of different components to form a continuous shielding path, so that external interference signals such as electromagnetic interference are blocked or attenuated, thereby reducing the risk of interference to the signals transmitted between different components.
[0049] In some embodiments, please refer to Figures 2 to 4 , the connector 1 includes a main housing 11, a shielding housing 12, and conductive terminals 13. The shielding housing 12 covers the main housing 11 and forms a receiving cavity 10. The conductive terminals 13 are arranged in the main housing 11, and at least part of the conductive terminals 13 is located in the receiving cavity 10. The conductive terminals 13 are used to electrically connect with the cable 2 and electrically connect with an external interface or other connectors 1. The shielding housing 12 is used to shield-connect with the cable 2 to play an electromagnetic shielding role for the cable 2 and the connector 1.
[0050] In some embodiments, the main housing 11 is provided with a receiving groove 110, and the shielding housing 12 covers the receiving groove 110 of the main housing 11 to form the receiving cavity 10.
[0051] In some embodiments, please refer to Figure 4 , the main housing 11 is respectively provided with a first limiting groove 111 and a second limiting groove 112 at both ends of the receiving groove 110. The first limiting groove 111 is used to receive at least part of the conductive terminals 13, and the second limiting groove 112 is used to limit and carry the cable 2.
[0052] In some embodiments, please refer to Figure 7, the cable 2 includes a conductor 21, a shielding layer 23, and a first insulating layer 24 arranged in sequence from the inside out. The shielding layer 23 is used to provide electromagnetic shielding for the conductor 21, and the first insulating layer 24 is used to provide electrical isolation and protection for the entire cable 2.
[0053] In some embodiments, the shielding layer 23 is formed by braiding a plurality of shielding conductors.
[0054] In the related art, a copper strip with grounding spikes is used. The grounding spikes of the copper strip pierce the first insulating layer of the coaxial cable, so that the grounding spikes are connected to the shielding layer of the coaxial cable, and then the copper strip is connected to the shielding housing to implement the shielding solution. However, the inventor further found that although the anti-electromagnetic interference effect is improved in this way, the shielding effect still fails to meet the expectation, and the signal transmission does not achieve an ideal effect. Through multiple detections, comparisons, and discussions, it is finally found that during the process of the grounding spikes piercing the first insulating layer and penetrating into the coaxial cable, the piercing force and angle of the grounding spikes are difficult to accurately control, which easily leads to damage to the shielding layer, deformation of the piercing copper strip, or position deviation, thereby resulting in a poor connection effect between the grounding spikes and the cable.
[0055] In view of this, in some embodiments, please refer to Figure 8 , along the extending direction of the cable 2, the cable 2 is provided with a connecting section 25 and a shielding section 26 that are sequentially connected. The connecting section 25 and the shielding section 26 are arranged in the receiving cavity 10. The conductor 21 of the connecting section 25 is electrically connected to the conductive terminal 13. The shielding section 26 has a welding area 261 where the first insulating layer 24 is not provided. The shielding layer 23 of the welding area 261 is welded to the first shielding member 3, and the first shielding member 3 is also electrically connected to the shielding housing 12 to achieve the shielding effect. In this embodiment, by welding the first shielding member 3 to the shielding layer 23 of the cable 2, the solution of using a copper strip and grounding spikes to pierce the first insulating layer is replaced, and the problem of poor connection effect caused by the difficult control of the piercing force and angle of the grounding spikes is solved. The welding connection method is beneficial to improving the reliability and stability of the connection between the first shielding member 3 and the shielding layer 23, and enhancing the shielding effect.
[0056] In some embodiments, the cable 2 is further provided with an extension section 27. Along the extending direction of the cable 2, the extension section 27 is connected to one end of the shielding section 26 away from the connecting section 25. The extension section 27 has a first insulating layer 24, and the extension section 27 is located outside the receiving cavity 10.
[0057] In some embodiments, please refer to Figure 7 and Figure 8 , the cable 2 further includes a second insulating layer 22. The connecting section 25 has an inner layer area 251 where the first insulating layer 24 and the shielding layer 26 are not provided. The second insulating layer 22 is provided on the outer ring of the inner layer area 251. The second insulating layer 25 is used to provide electrical isolation and protection for the conductor 21 in the inner layer area 251.
[0058] In some embodiments, the second insulating layer 22 is disposed around the conductor 21 of the overall cable 2, and the second insulating layer 22 is disposed between the conductor 21 and the shielding layer 23. For example, the second insulating layer 22 is provided outside the conductors 21 of the connection section 25, the shielding section 26, and the extension section 27. The second insulating layer 22 is used to isolate the conductor 21 from the shielding layer 23, reduce the risk of short circuit between the conductor 21 and the shielding layer 23, and at the same time provide mechanical protection to enhance the durability of the cable 2.
[0059] In some other embodiments, only the conductor 21 of the connection section 25 is provided with the second insulating layer 22, and the conductors 21 of the shielding section 26 and the extension section 27 are not provided with the second insulating layer 22.
[0060] In some embodiments, please refer to Figure 8 , the number of the cables 2 is multiple, and the multiple cables 2 are arranged in parallel. A first shielding member 3 is disposed on one side of the multiple cables 2, and the first shielding member 3 is welded to the welding areas 261 of the multiple cables 2, so that the first shielding member 3 can cover the multiple cables 2 at the same time, forming a continuous shielding structure, which helps to block or attenuate external electromagnetic interference.
[0061] Compared with the solution of piercing the copper strip grounding spike, in this embodiment, the first shielding member 3 and the multiple cables 2 are shielded and connected by welding, which not only improves the reliability of the electrical connection between each cable 2 and the first shielding member 3, reduces the risk of signal leakage or electromagnetic interference caused by poor connection, but also improves the durability of the connector assembly 1000, and reduces the risk of loosening of the connection between the cable 2 and the first shielding member 3 due to vibration or impact during long-term use.
[0062] In addition, it should be noted that in the solution of piercing the copper strip grounding spike in the related art, when the number of the cables 2 is multiple, the copper strip correspondingly has multiple grounding spikes. Based on the inventor's multiple studies, it is found that when there are multiple grounding spikes, there are still dimensional deviations between the multiple grounding spikes, and the dimensional deviations are amplified based on the increase in the number. Moreover, with the increase of the grounding spikes, it is more difficult to accurately control the piercing force and angle of each grounding spike, and usually there will be problems of poor communication of several cables. In the embodiment of the present application, the first shielding member 3 is welded to the welding areas 261 of the multiple cables 2, which not only does not require the alignment and calibration of the positions of each cable and each shielding connection component (grounding spike), greatly improves the connection effect between the first shielding member 3 and the multiple cables 2, but also simplifies the structure of the connector assembly 1000, reduces the processing difficulty, reduces the number of components, and reduces the manufacturing cost.
[0063] In some embodiments, along the radial direction of the cable 2, the connector assembly 1000 further includes a second shielding member 5 ,In the radial direction along the cable 2, the second shielding member 5 is disposed on the side of the shielding section 26 away from the first shielding member 3.
[0064] In an embodiment where there are multiple cables 2, both the first shielding member 3 and the second shielding member 5 are welded to the shielding layer 23 of the welding area 261 of the multiple cables 2, further enhancing the shielding effect and connection strength.
[0065] In some embodiments, please refer to Figure 8 , a first welding medium layer 4 is provided between the first shielding member 3 and the shielding layer 23 of the shielding section 26. The reliable welding of the first shielding member 3 to the cable 2 is achieved through the first welding medium layer 4, reducing the risk of damaging the shielding layer 23 of the cable 2 due to direct welding.
[0066] In some embodiments, a first welding medium layer 4 is also provided between the second shielding member 5 and the shielding layer 23 of the shielding section 26. The reliable welding of the second shielding member 5 to the cable 2 is achieved through the second welding medium layer 4, reducing the risk of damaging the shielding layer 23 of the cable 2 due to direct welding.
[0067] In some embodiments, the main housing 11 is provided with a limiting post 14 in the receiving groove 110. When the first shielding member 3, the second shielding member 5 and the cable 2 are disposed in the receiving cavity 10 of the connector 1, the second shielding member 5 on the side of the cable 2 away from the shielding housing 12 is limited and fixed by the limiting post 14, further enhancing the connection stability between the cable 2 and the connector 1.
[0068] In some embodiments, along the direction in which the shielding housing 12 covers the main housing 11, the shielding housing 12, the first shielding member 3, the cable 2, the second shielding member 5 and the limiting post 14 are arranged in sequence.

[0075] In some embodiments, there are multiple conductive terminals 13 , and the conductive terminals 13 are connected to the cables 2 in a one-to-one correspondence.
[0076] In some embodiments, see Figure 6 and Figure 9 The conductive terminal 13 is provided with a piercing portion 131. After the piercing portion 131 passes through the second insulating layer 22 of the connecting section 25, it contacts the conductor 21 of the connecting section 25, thereby realizing a piercing electrical connection between the conductive terminal 13 and the cable 2. Compared with the direct contact electrical connection between the conductive terminal 13 and the conductor 21 of the cable 2, the second insulating layer 22 of the cable 2 and the piercing portion are tightly connected when the piercing electrical connection is adopted, and no additional welding or fixing parts are required, which simplifies the installation process and improves the installation efficiency and maintainability.
[0077] In some embodiments, see Figure 6 The piercing portion 131 is provided with a piercing groove 1310, and the piercing groove 1310 includes a guide section 1311 and a piercing section 1312.

The limit member 15 is located on the side of the connecting section 25 of the cable 2 away from the main shell 11. The limit member 15 covers at least a portion of the conductive terminal 13 and at least a portion of the connecting section 25 to limit and fix the connection between the connecting section 25 and the conductive terminal 13, thereby reducing the risk of loosening the connection between the cable 2 and the conductive terminal 13 due to the arching of the connecting section 25.
[0079] In some embodiments, the limiting member 15 covers the connecting section 25 of the cable 2 and the piercing portion 131 of the conductive terminal 13 .

[0083] In some embodiments, refer to Figure 10 , a second welding medium layer 6 is provided between the first shielding member 3 and the shielding case 12, and the second welding medium layer 6 connects the first shielding member 3 and the shielding case 12. The reliable welding between the first shielding member 3 and the shielding case 12 is achieved through the second welding medium layer 6, which not only reduces the risk of damaging the structures of the first shielding member 3 and the shielding case 12 due to direct welding, but also improves the practicability of the connector assembly 1000. By adjusting the thickness of the second welding medium layer 6, it can adapt to the first shielding member 3 and the shielding case 12 with different spacings.
[0084] In some embodiments, the second shielding member 5 is welded to the shielding case 12 to achieve electrical connection between the second shielding member 5 and the shielding case 12. The second shielding member 5 and the shielding case 12 are fixedly electrically connected by welding through the second welding medium layer 6, which enhances the reliability of the shielding connection compared with the abutting connection.
[0085] In some embodiments, the second welding medium layer 6 connects the second shielding member 5 and the shielding case 12. The reliable welding between the second shielding member 5 and the shielding case 12 is achieved through the second welding medium layer 6, which not only reduces the risk of damaging the structures of the second shielding member 5 and the shielding case 12 due to direct welding, but also improves the practicability of the connector assembly 1000. By adjusting the thickness of the second welding medium layer 6, it can adapt to the second shielding member 5 and the shielding case 12 with different spacings

[0100] Specifically, the main housing is made of an insulating material, and the shielding housing and the conductive terminals are made of conductive materials. The main housing is provided with a receiving groove, and the main housing is provided with a plurality of first limiting grooves at one end of the receiving groove. The number of the conductive terminals is multiple, and one conductive terminal is installed in one first limiting groove.
[0101] In some embodiments, the cable includes a conductor, a shielding layer, and a first insulating layer arranged in sequence from inside to outside. The number of the cables is multiple. In some embodiments, the first shielding member is made of metal, alloy, or other conductive materials, the shape of the first shielding member is rectangular parallelepiped, and the length direction of the first shielding member is parallel to the arrangement direction of the multiple cables.
[0102] Please refer to Figure 11 , the manufacturing method of the connector assembly 1000 includes:
[0103] Step S10: Strip the end of the cable, remove part of the first insulating layer and the shielding layer of the cable to obtain a connection section, and remove part of the first insulating layer of the cable to obtain a shielding section.
[0104] In some embodiments, before stripping the end of the cable, the multiple cables are arranged in parallel, the number and spacing of the cables are determined according to the specifications of the main housing, and then they are fixed with a peelable tape. The arrangement and spacing of the multiple cables match the multiple conductive terminals.
[0105] In some embodiments, please refer to Figure 12 , Figure 12 is Figure 11 a sub-process of step S10 in
[0106] Step S11: Perform a first stripping process on the end of the cable to remove part of the first insulating layer of the cable to obtain a transition section without the first insulating layer;
[0107] Specifically, in some embodiments, first, a gas laser such as a CO2 laser is used to cut part of the first insulating layer at one or both ends of the cable, and then a displacement tool is used to displace and remove the part of the first insulating layer to obtain a transition section at one or both ends of the cable. The axial length of the transition section is determined according to the specifications of the connector and application requirements.
[0108] Step S12: Perform a second peeling process on the end of the cable to remove the shielding layer of a part of the transition section, so as to obtain a connection section without the first insulating layer and the shielding layer and a shielding section without the first insulating layer.
[0109] Specifically, in some embodiments, first cut the shielding layer of a part of the transition section through a solid-state laser such as a YAG (Yttrium Aluminum Garnet) laser, then use a displacement tool to displace and remove this part of the shielding layer, and then clean and remove dust from the cable, so as to form a connection section without the first insulating layer and the shielding layer and a shielding section without the first insulating layer in the transition section. The connection section and the shielding section are arranged in sequence along the extending direction of the cable, and the axial length of the connection section and the axial length of the extending section are determined according to the specifications of the connector and the shielding member and application requirements.
[0110] In some embodiments, the cable further includes a second insulating layer, the second insulating layer is disposed around the conductor and between the conductor and the shielding layer.

[0111] In some embodiments, along the extending direction of the cable, the cable is sequentially provided with a pre-cut section, a connection section, a shielding section, and an extending section, and the pre-cut section and the extending section have the first insulating layer. That is, in the process of peeling the end of the cable, first reserve a section of the cable without peeling as the pre-cut section to improve the accuracy of the peeling operation and the convenience of subsequent processing. When the peeling operation is inaccurate or subsequent processing requires adjustment, the pre-cut section is operated and adjusted.
[0112] Step S20: Weld the first shielding member to the shielding section.
[0113] In some embodiments, please refer to Figure 13 , Figure 13 Yes Figure 11 A sub-process of step S20 in
[0114] Step S21: Place the first shielding member outside the shielding section.
[0115] Specifically, in some embodiments, the shielding section is provided with a welding area, and the axial length of the welding area is greater than or equal to the width of the shielding member. Fix the first shielding member and the cable through a welding die, place the first shielding member and the shielding section of the cable in the welding die, and the first shielding member is located outside the welding area.
[0116] Step S22: Provide a first welding medium and fill the first welding medium between the shielding member and the first shielding section.
[0117] Specifically, the first welding medium is solder paste, conductive adhesive or other conductive welding materials. Through a dispensing device, the first welding medium is applied to the gap between the first shielding member and the shielding layer of the welding area.
[0118] Step S23: Heat and then cool the first welding medium to form a first welding medium layer between the first shielding member and the shielding layer of the shielding section.
[0119] Specifically, the first welding medium is heated by a heating device to melt it and fill the gap between the first shielding member and the shielding layer. After heating is completed, it is naturally cooled or cooled by a cooling device to accelerate cooling, so that the first welding medium solidifies to form a firm first welding medium layer, thereby electrically connecting and fixing the first shielding member and the shielding layer of the welding area together.
[0120] In some embodiments, the length of the provided first shielding member is greater than the arrangement length of the plurality of cables. After welding the first shielding member to the shielding section, the redundant length portion of the shielding member is cut off by a cutting tool.
[0121] In some embodiments, after the step of stripping the ends of the cables or after the step of welding the first shielding member to the shielding section, the pre-cut section of the cables is cut off by a cutting tool.
[0122] In other embodiments, the connector assembly further includes a second shielding member. The second shielding member is made of metal, alloy or other conductive materials. The shape of the second shielding member is rectangular parallelepiped, and the length direction of the second shielding member is parallel to the arrangement direction of the plurality of cables.

Arrange the first shielding member, the second shielding member and the shielding section of the cable in a welding mold. The second shielding member is located on the side of the welding area along the radial direction of the cable away from the first shielding member.
[0125] Fill the first welding medium between the second shielding member and the shielding section. Through a dispensing device, the first welding medium is applied to the gap between the second shielding member and the shielding layer of the welding area.
[0126] The first welding medium is heated and then cooled to form a first welding medium layer, and the first welding medium layer connects the second shielding member and the shielding section. The first welding medium is heated by a heating device to melt it and fill the gap between the second shielding member and the shielding layer. After heating is completed, it is cooled naturally or the cooling is accelerated by a cooling device, so that the first welding medium solidifies to form a firm first welding medium layer, thereby electrically connecting and fixing the second shielding member and the shielding layer of the welding area together.
[0127] In some embodiments, the steps of welding the first shielding member to the shielding section and the step of welding the second shielding member are carried out separately or simultaneously. When the steps of welding the first shielding member to the shielding section and the step of welding the second shielding member are carried out separately, the order of these two steps is not limited.
[0128] In some embodiments, while welding the first shielding member to the shielding section, the second shielding member is welded to the shielding section. Specifically, it includes the following steps:
[0129] The first shielding member and the second shielding member are placed on both sides of the shielding section along the radial direction of the cable. The first shielding member, the second shielding member and the shielding section of the cable are arranged in a welding die, and the first shielding member and the second shielding member are respectively located on both sides of the welding area along the radial direction of the cable.
[0130] The first welding medium is provided, and the first welding medium is filled between the first shielding member and the second shielding member. Through a dispensing device, the first welding medium is applied to the gap between the first shielding member, the shielding layer of the welding area and the second shielding member.
[0131] The first welding medium is heated and then cooled to form a first welding medium layer, and the first welding medium layer connects the first shielding member, the welding area and the second shielding member. The first welding medium is heated by a heating device to melt it and fill the gap between the first shielding member, the shielding layer and the second shielding member. After heating is completed, it is cooled naturally or the cooling is accelerated by a cooling device, so that the first welding medium solidifies to form a firm first welding medium layer, thereby electrically connecting and fixing the first shielding member, the shielding layer of the welding area and the second shielding member together.
[0132] In some embodiments, the lengths of the provided first shielding member and the second shielding member are both greater than the arrangement length of the plurality of cables. After welding the first shielding member, the second shielding member and the shielding section, the redundant length of the shielding member part is cut off by a cutting tool.
[0133] Step S30: Place the end of the cable and the first shielding member in the main housing, and electrically connect the conductor of the connecting section to the conductive terminal.
[0134] Specifically, the conductive terminal is provided with a piercing portion. The main housing is provided with a plurality of second limiting grooves at the other end of the receiving groove. Place one end of the cable extension near the shielding section in the second limiting groove, and place the inner layer area of the cable correspondingly on the piercing portion of the conductive terminal.
[0135] In some embodiments, the end of the cable, the first shielding member, and the second shielding member are placed in the main housing together, and the second shielding member is limited and fixed by the limiting posts.
[0136] Next, please refer to Figure 14 , Figure 14 which is Figure 11 a sub - process of step S30 in
[0137] Step S31: Press the connection section towards the conductive terminal so that the conductive terminal contacts the conductor of the connection section to form an electrical connection.
[0138] Specifically, in some embodiments, the piercing portion is provided with a piercing groove, and the piercing groove includes a guiding section and a piercing section. Apply pressure to the inner layer area of the cable through a pressing tool, so that the inner layer area passes through the guiding section and then inserts into the piercing section. After the piercing section penetrates the second insulating layer of the inner layer area, it contacts the conductor, thereby realizing an electrical connection.
[0139] In some embodiments, after the inner layer area of the cable inserts into the piercing section of the conductive terminal, use a CCD (charge - coupled device) camera to magnify and observe the connection between the cable and the conductive terminal to inspect the piercing effect.
[0140] In some embodiments, the connector further includes a limiting member. After determining that the conductor of the inner layer area of the cable contacts the conductive terminal, cover and install the limiting member on the connection section of the cable and the piercing portion of the conductive terminal, which is used to reduce the risk of the electrical connection between the cable and the conductive terminal becoming loose due to the arching of the connection section.
[0141] In some embodiments, before covering the shielding shell on the main housing, perform semi - finished product inspection on the semi - finished product of the connector assembly assembled with the main housing, the limiting member of the conductive terminal, the cable, and the shielding member, including but not limited to electrical continuity test, insulation resistance test, and shielding effectiveness test.
[0142] Step S40: Cover the shielding shell on the main housing to form a receiving cavity, so that at least part of the conductive terminal, at least part of the first shielding member, the connection section, and the shielding section are located in the receiving cavity.
[0143] Specifically, the shielding case is snap-fitted to the main case, or fixed to the main case by fasteners such as screws, so that the shielding case fixedly covers the receiving groove of the main case, thereby forming a receiving cavity.

[0146] Specifically, please refer to Figure 15 , Figure 15 which is Figure 11 a sub-process of step S50 in
[0147] Step S51: Provide a second welding medium and fill the second welding medium between the shielding case and the first shielding member.
[0148] Specifically, the second welding medium is solder paste, conductive adhesive or other conductive welding materials. In some embodiments, through holes are provided in the circumferential direction of the structural member of the shielding case. Using a dispensing device, the second welding medium is applied from the through holes to the gap between the structural member and the first shielding member.
[0149] Step S52: Heat the second welding medium and then cool it to form a second welding medium layer between the shielding case and the first shielding member.
[0150] Specifically, the second welding medium is heated by a heating device to make it melt and fully fill the gap between the structural member of the shielding case and the first shielding member. After heating, natural cooling or a cooling device is used to accelerate the cooling process, so that the second welding medium solidifies to form a firm second welding medium layer, thereby realizing a reliable electrical connection between the shielding case and the first shielding member.
[0151] In some embodiments, please refer to Figure 11 , after the step of electrically connecting the shielding case to the first shielding member, the manufacturing method further includes:
[0152] Step S60: Fix the cable to the main case.
[0153] Specifically, through a dispensing tool, a bonding medium is filled between the extending section of the cable and the second limiting groove of the main case to bond and fix the cable to the main case.
[0154] In some embodiments, a bonding medium is also filled between the extending section of the cable and the edge of the shielding case through a dispensing tool to bond and fix the cable to the shielding case.
[0155] In some embodiments, after the cable is fixedly connected to the main housing, a protective film is wrapped around the cable extension section located outside the receiving cavity to protect the cable portion located outside the receiving cavity.
[0156] Step S70: Perform appearance inspection, dimensional inspection, and performance inspection.
[0157] Specifically, the assembled connector, cable, and shield form a connector assembly 1000. The appearance inspection is performed by magnifying with a CCD camera; the dimensional inspection and recording are performed with measuring tools; the performance inspection and recording are performed with test equipment. The performance inspection includes but is not limited to electrical continuity test, insulation resistance test, and shielding effectiveness test.
