It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element or one or more intervening elements can be present therebetween. When an element is described as "connected to" another element, it can be directly connected to the other element or one or more intervening elements can be present therebetween.

[0040] Unless otherwise defined, all technical and scientific terms used in the present application have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the present application are only for the purpose of describing specific embodiments of the present application and are not intended to limit the present application. The term "and / or" used in the present application includes any and all combinations of one or more related listed items.

[0041] In the related art, the assembly of the connector and the plurality of coaxial cables is widely used in the fields of unmanned aerial vehicles, high-definition cameras, vehicle-mounted display systems, etc. The communication precision of the connector assembly is required to be very high, and therefore there is a high demand for the connection between the conductive terminal and the coaxial cable to resist electromagnetic interference. How to improve the electromagnetic interference resistance at this position is a problem to be solved in the industry.

[0042] Therefore, the inventors found during the research and development that a shielding shell can be arranged on the connector, and the shielding shell is connected with the shielding layer of the coaxial cable to provide a continuous shielding path to resist electromagnetic interference on the conductive terminal and the cable connection part in the accommodation cavity.

[0043] The embodiments of the present application provide a connector assembly 1000 and a manufacturing method of the connector assembly 1000, which are beneficial to improve the shielding connection reliability of the cable and the connector and enhance the shielding effect

[0044] 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 with the connector 1, and the first shielding member 3 is used to shield and connect the cable 2 and the connector 1.

[0045] Shielding connection refers to establishing a conductive 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 of signals transmitted between different components.

[0046] In some embodiments, please refer to Figures 2 to 4The connector 1 comprises a main housing 11, a shielding shell 12 and a conductive terminal 13. The shielding shell 12 covers the main housing 11 and forms the receiving cavity 10. The conductive terminal 13 is arranged on the main housing 11 and at least partially located in the receiving cavity 10. The conductive terminal 13 is used for electrical connection with the cable 2 and electrical connection with the external interface or other connectors 1. The shielding shell 12 is used for shielding connection with the cable 2 to achieve electromagnetic shielding effect of the cable 2 and the connector 1.

[0047] In some embodiments, the main housing 11 is provided with a receiving groove 110, and the shielding shell 12 covers the receiving groove 110 of the main housing 11 to form the receiving cavity 10.

[0048] In some embodiments, referring to Figure 4 The main housing 11 is 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 for receiving at least part of the conductive terminal 13, and the second limiting groove 112 is used for limiting the cable 2.

[0049] In some embodiments, referring to Figure 7 The cable 2 comprises a conductor 21, a shielding layer 23 and a first insulating layer 24 arranged in sequence from inside to outside. The shielding layer 23 is used for electromagnetic shielding effect of the conductor 21, and the first insulating layer 24 is used for providing electrical isolation and protection effect for the whole cable 2.

[0050] In some embodiments, the shielding layer 23 is formed by a plurality of shielding conductors.

[0051] In the related art, a copper strip with a grounding spike is used to pierce the first insulating layer of the coaxial cable, so that the grounding spike is connected with the shielding layer of the coaxial cable, and then the copper strip is connected with the shielding shell to achieve the shielding scheme. However, the inventors have 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 the ideal effect. Through repeated detection, comparison and discussion, it is finally found that the force and angle of the grounding spike piercing the first insulating layer and penetrating into the coaxial cable are difficult to accurately control in the process of piercing the first insulating layer, which easily leads to damage of the shielding layer, deformation or position deviation of the piercing copper strip, and further leads to poor connection effect of the grounding spike and the cable.

[0052] In view of this, in some embodiments, referring to Figure 8, along the extending direction of the cable 2, the cable 2 is provided with the connecting section 25 and the shielding section 26 connected in sequence, and the connecting section 25 and the shielding section 26 are arranged in the accommodating cavity 10. The conductor 21 of the connecting section 25 is electrically connected with the conductive terminal 13. The shielding section 26 has a welding area 261 without the first insulation layer 24, and the shielding layer 23 of the welding area 261 is welded with the first shielding member 3, and the first shielding member 3 is also electrically connected with the shielding shell 12 to achieve the shielding effect. In the embodiment, the first shielding member 3 is welded with the shielding layer 23 of the cable 2, instead of the scheme of piercing the first insulation layer by the copper strip and the grounding spike, so as to solve the problem of poor connection effect caused by the difficulty in controlling the piercing force and angle of the grounding spike. The welding connection mode is conducive 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.

[0053] In some embodiments, the cable 2 is also provided with an extending section 27, along the extending direction of the cable 2, the extending section 27 is connected to one end of the shielding section 26 away from the connecting section 25, and the extending section 27 has the first insulation layer 24, and the extending section 27 is located outside the accommodating cavity 10.

[0054] In some embodiments, referring to Figure 7 and Figure 8 , the cable 2 further comprises a second insulation layer 22, the connecting section 25 has an inner layer area 251 without the first insulation layer 24 and the shielding layer 26, and the second insulation layer 22 is arranged outside the inner layer area 251, and the second insulation layer 25 is used to provide electrical isolation and protection for the conductor 21 of the inner layer area 251.

[0055] In some embodiments, the second insulation layer 22 is arranged outside the conductor 21 of the whole cable 2, and the second insulation layer 22 is arranged between the conductor 21 and the shielding layer 23. For example, the second insulation layer 22 is arranged outside the conductor 21 of the connecting section 25, the shielding section 26 and the extending section 27. The second insulation layer 22 is used to isolate the conductor 21 and the shielding layer 23, reduce the risk of short circuit between the conductor 21 and the shielding layer 23, and provide mechanical protection, thereby enhancing the durability of the cable 2.

[0056] In some other embodiments, the second insulation layer 22 is arranged outside the conductor 21 of only the connecting section 25, and the second insulation layer 22 is not arranged outside the conductor 21 of the shielding section 26 and the extending section 27.

[0057] In some embodiments, referring to Figure 8 , the number of the cables 2 is multiple, and the multiple cables 2 are arranged in parallel with each other, and the first shielding member 3 is arranged on one side of the multiple cables 2, and the first shielding member 3 is welded with the welding area 261 of the multiple cables 2, so that the first shielding member 3 can cover the multiple cables 2 at the same time, and form a continuous shielding structure, which is helpful to block or attenuate the electromagnetic interference from the outside.

[0058] Compared with the scheme of piercing the copper strip grounding spike, the first shielding member 3 and the plurality of cables 2 are connected by welding in the embodiment, which not only improves the electrical connection reliability of 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 loose connection between the cable 2 and the first shielding member 3 caused by vibration or impact during long-term use.

[0059] In addition, it should be noted that in the related art, when the number of cables 2 is multiple, the copper strip has multiple grounding spikes. Based on the inventor's research, when there are multiple grounding spikes, there is a size deviation between the multiple grounding spikes. The size deviation is amplified based on the increase in the number, and it is more difficult to accurately control the force and angle of piercing of each grounding spike. Therefore, there is usually a problem of poor communication of several cables. In the embodiment of the present application, the welding area 261 of the first shielding member 3 and the plurality of cables 2 are welded, which not only eliminates the need for position corresponding calibration of each cable and each shielding connecting part (grounding spike), greatly improves the connection effect between the first shielding member 3 and the plurality of cables 2, but also simplifies the structure of the connector assembly 1000, reduces the processing difficulty, reduces the number of parts, and reduces the manufacturing cost.

[0060] In some embodiments, along the radial direction of the cable 2, the connector assembly 1000 further comprises a second shielding member 5, which is arranged on the side of the shielding section 26 away from the first shielding member 3 along the radial direction of the cable 2.

[0061] In the embodiment in which the cable 2 is multiple, the first shielding member 3 and the second shielding member 5 are welded with the shielding layer 23 of the welding area 261 of the plurality of cables 2, which further enhances the shielding effect and the connection strength.

[0062] In some embodiments, referring to Figure 8 , a first welding medium layer 4 is arranged between the first shielding member 3 and the shielding layer 23 of the shielding section 26, and the reliable welding of the first shielding member 3 and the cable 2 is realized through the first welding medium layer 4, which reduces the risk of damaging the shielding layer 23 of the cable 2 caused by direct welding.

[0063] In some embodiments, a first welding medium layer 4 is also arranged between the second shielding member 5 and the shielding layer 23 of the shielding section 26, and the reliable welding of the second shielding member 5 and the cable 2 is realized through the second welding medium layer 4, which reduces the risk of damaging the shielding layer 23 of the cable 2 caused by direct welding.

[0064] In some embodiments, the main shell 11 is provided with a limiting post 14 at the receiving groove 110. When the first shielding member 3, the second shielding member 5 and the cable 2 are arranged in the receiving cavity 10 of the connector 1, the second shielding member 5 located at the side of the cable 2 away from the shielding shell 12 is limited and fixed by the limiting post 14, further enhancing the connection stability of the cable 2 and the connector 1.

[0065] In some embodiments, the shielding shell 12, the first shielding member 3, the cable 2, the second shielding member 5 and the limiting post 14 are sequentially arranged in the direction in which the shielding shell 12 covers the main shell 11.

[0066] In some embodiments, the first shielding member 3 is made of metal, alloy or other conductive material. As an exemplary example, the first shielding member 3 is a copper strip.

[0067] In some embodiments, the second shielding member 5 is made of metal, alloy or other conductive material. As an exemplary example, the second shielding member 5 is a copper strip.

[0068] In some embodiments, the first shielding member 3 and the second shielding member 5 are made of the same material.

[0069] In some embodiments, the first shielding member 3 has a cuboid shape, and the length direction of the first shielding member 3 is parallel to the arrangement direction of the plurality of cables 2.

[0070] In some embodiments, the second shielding member 5 has a cuboid shape, and the length direction of the second shielding member 5 is parallel to the arrangement direction of the plurality of cables 2.

[0071] In some embodiments, the second shielding member 5 is electrically connected to the shielding shell 12 to enhance the shielding effect.

[0072] In some embodiments, the number of conductive terminals 13 is multiple, and the conductive terminals 13 are connected to the cables 2 one by one.

[0073] In some embodiments, referring to Figure 6 and Figure 9 , the conductive terminal 13 is provided with a piercing part 131, which pierces through the second insulating layer 22 of the connecting segment 25 and contacts the conductor 21 of the connecting segment 25, so as to realize the piercing type 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 piercing type electrical connection has the second insulating layer 22 of the cable 2 closely connected with the piercing part, without the need for additional welding or fixing components, simplifying the installation process and improving the installation efficiency and maintainability.

[0074] In some embodiments, referring to Figure 6The piercing part 131 is provided with a piercing groove 1310, which includes a guide section 1311 and a piercing section 1312. The guide section 1311 is used to guide the connection section 25 of the cable 2 to be smoothly inserted, and the piercing section 1312 is used to penetrate the second insulating layer 22 of the connection section 25 to contact the conductor 21.

[0075] In some embodiments, referring to Figures 3 to 5 The connector 1 further includes a limiting piece 15 connected with the main shell 11. The limiting piece 15 is located on the side of the connection section 25 of the cable 2 away from the main shell 11, and covers at least part of the conductive terminal 13 and at least part of the connection section 25 to limit and fix the connection between the connection section 25 and the conductive terminal 13, thereby reducing the risk of loose connection between the cable 2 and the conductive terminal 13 due to arching of the connection section 25.

[0076] In some embodiments, the limiting piece 15 covers the connection section 25 of the cable 2 and the piercing part 131 of the conductive terminal 13.

[0077] In some embodiments, the side of the limiting piece 15 facing the main shell 11 is provided with a plurality of third limiting grooves 151 and a plurality of fourth limiting grooves 152. The conductive terminal 13 is arranged in one-to-one correspondence in the third limiting groove 151, and the connection section 25 of the cable 2 is arranged in one-to-one correspondence in the fourth limiting groove 152, thereby not only helping the neat arrangement of the cable 2, but also enhancing the connection strength between the cable 2 and the connector 1.

[0078] In some embodiments, the two ends of a third limiting groove 151 are respectively provided with a fourth limiting groove 152.

[0079] In some embodiments, referring to Figure 10 The first shielding piece 3 is welded with the shielding shell 12 to realize electrical connection between the first shielding piece 3 and the shielding shell 12.

The reliable welding of the first shielding piece 3 and the shielding shell 12 is realized through the second welding medium layer 6, which not only reduces the risk of damaging the structure of the first shielding piece 3 and the shielding shell 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, the first shielding piece 3 and the shielding shell 12 with different intervals can be adapted.

[0081] In some embodiments, the second shielding member 5 is welded with the shielding shell 12 to achieve electrical connection between the second shielding member 5 and the shielding shell 12. The second shielding member 5 and the shielding shell 12 are fixedly connected by the second welding medium layer 6, which enhances the reliability of the shielding connection compared with the abutting connection.

[0082] In some embodiments, the second welding medium layer 6 connects the second shielding member 5 and the shielding shell 12 to achieve reliable welding between the second shielding member 5 and the shielding shell 12. This not only reduces the risk of damaging the structure of the second shielding member 5 and the shielding shell 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, the second shielding member 5 and the shielding shell 12 with different spacings can be adapted.

[0083] In some embodiments, the shielding shell 12 is provided with a through hole 120 for the second welding medium to pass through. The second welding medium solidifies to form the second welding medium layer 6.

[0084] In some embodiments, referring to Figure 1 and Figure 2 , the shielding shell 12 is provided with a structural member 121 at the through hole 120.

[0087] In some embodiments, the first welding medium and the second welding medium are one or more of solder paste, conductive glue, or other conductive welding materials.

[0088] In some embodiments, the cable 2 is provided with a connector 1 and a first shielding member 3 at both ends, thereby improving the flexibility and practicability of the connector assembly 1000. The welding areas 261 at both ends of the cable 2 are respectively welded with a first shielding member 3, and a first shielding member 3 is electrically connected with a shielding shell 12 of a connector 1.

After heating, the first welding medium is naturally cooled or accelerated by the cooling device to solidify and form a firm first welding medium layer, thereby electrically connecting and fixing the second shield and the shielding layer of the welding area together.

[0124] In some embodiments, the step of welding the first shield to the shield segment and the step of welding the second shield are performed separately or simultaneously.
