Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, specifically to a FAKRA angled vehicle camera connector and its manufacturing method. Background Technology

[0002] Traditional camera connectors typically use a vertical insertion structure, meaning the connector's insertion direction is perpendicular to the back cover plane. However, in practical applications, due to compact internal layouts, space constraints, or wiring angle requirements, camera connectors with an angled design are often necessary to avoid interference with other components.

[0003] Existing camera connector technologies, such as the "Connector with a Large Angled FAKRA to SMP Port" disclosed in Chinese Patent CN223309248U, although achieving a tilted design for the camera connector insertion direction, have the following drawbacks in practical use:

[0004] 1. The plastic shell is an essential component of this connector. However, due to its extremely low thermal conductivity, heat accumulates inside the conductor and cannot dissipate. For low-pixel automotive cameras (1-2 megapixels), the image sensor has low data processing requirements, low frame rate, and extremely low power consumption, resulting in minimal heat generation and a relatively low overall temperature rise during normal operation. However, for mid-to-high-pixel automotive cameras (3-8 megapixels), with the pixel count doubling, image sampling, signal transmission, and image processing power increase significantly. This leads to a surge in power consumption and sustained high heat generation in the camera module. Prolonged operation causes concentrated heat buildup, which can easily lead to internal overheating, affecting image quality and accelerating plastic aging.

[0005] 2. The connector has a mating groove on its outer conductor that mates with the inclined body, which can easily form a mating gap in the circumferential direction, resulting in electromagnetic leakage and reducing the electromagnetic shielding performance of the connector.

[0006] 3. The connector's structure relies excessively on the plastic shell for fixation, resulting in limited fatigue life and poor reliability. Especially under repeated insertion and removal and vibration environments, the plastic shell is prone to deformation and connector fixing components may fail.

[0007] 4. Waterproof sealing of connectors can only be achieved by using multi-component discrete sealant or sealant. Independent sealant or supplementary sealant needs to be applied to multiple locations such as mating surface, shell split surface, and terminal through holes. Failure at any one location will lead to overall waterproof failure. With long-term use, there is a risk of multiple nodes failing simultaneously after aging.

[0008] 5. This connector has many components, and the assembly process is cumbersome, complex, and has low production efficiency, which can easily lead to assembly errors, thereby affecting the connector's transmission performance and waterproof sealing performance.

[0009] In addition, the aforementioned defects can also cause a series of problems, such as deformation of the plastic shell disrupting the intended sealing state, and complex sealing structures limiting the optimization space for shell materials.

[0010] Therefore, there is an urgent need for an angled vehicle camera connector with good shielding and heat dissipation performance and reliable connection, which can simplify assembly steps, improve production efficiency, ensure waterproof performance, and enable multi-scenario connection to improve product practicality. Summary of the Invention

[0011] This invention provides a FAKRA angled vehicle camera connector and its manufacturing method, overcoming the problems in the prior art. The technical solution adopted by this invention is as follows:

[0012] A FAKRA angled vehicle camera connector includes: a metal rear cover having a mounting panel, a rear cover sidewall, a mounting hole formed on the mounting panel, and an accommodating cavity formed by the mounting panel and the rear cover sidewall;

[0013] A terminal assembly, including a center terminal and an insulator sleeved on the outside of the center terminal;

[0014] The first outer conductor is an integral metal structure, including a mounting part, a plug-in part, and a first cavity formed inside the first outer conductor to accommodate the terminal assembly; the mounting part is also provided with a clearance groove, which is formed along the axis of the plug-in part and communicates with the first cavity, so that the terminal assembly can be installed into the first cavity along the axis of the plug-in part; a FAKRA connector is integrally formed on the outer side of the plug-in part; a preset angle is formed between the axis of the plug-in part and the axis of the mounting part; the mounting part is perpendicular to the mounting panel and plugged into and fixed in the mounting hole; and a non-perpendicular angle is formed between the axis of the plug-in part and the mounting panel.

[0015] The second outer conductor has a hollow cylindrical metal structure, and its interior is provided with a second cavity for the terminal assembly to pass through and fit. The second outer conductor is coaxially installed in the mounting part. The second outer conductor and the first outer conductor together form a circumferentially continuous cylindrical shielding structure.

[0016] The sealant includes a first sealant filled in the accommodating cavity of the metal rear cover and a second sealant filled in the first cavity of the first outer conductor;

[0017] The end of the mounting part is riveted to the second outer conductor and the metal back cover to form a riveting part, so that the first outer conductor, the second outer conductor, and the metal back cover are fixedly connected into an integral structure.

[0018] Furthermore, the insulator is integrally formed, including an inclined body and an upright end connected to the inclined body. A recess is formed at the connection between the inclined body and the upright end, and the inclined body has a receiving surface at the recess that is perpendicular to the axis of the plug-in portion, for receiving external thrust to insert the terminal assembly into a predetermined position in the first cavity.

[0019] Furthermore, the mounting portion penetrates the mounting hole, the inner edge of the end face of the mounting portion is riveted to the second outer conductor to form a first riveting portion, and the outer edge of the end face of the mounting portion is riveted to the metal back cover to form a second riveting portion.

[0020] Furthermore, an annular platform is provided on the outer side wall of one end of the second outer conductor, and an annular groove communicating with the first cavity is provided in the mounting part, and the annular platform of the second outer conductor is installed in the annular groove of the first outer conductor.

[0021] Furthermore, a protrusion is provided on the outer end face of the ring platform of the second outer conductor, and a limiting groove communicating with the ring groove is provided on the inner wall of the mounting part. The protrusion and the limiting groove cooperate to form a limiting structure to prevent the insulator from coming out of the second outer conductor.

[0022] Furthermore, the inner wall of the mounting part is provided with an anti-rotation groove, and the insulator is provided with an anti-rotation protrusion. The anti-rotation groove and the anti-rotation protrusion are matched in a limiting manner to restrict the insulator from rotating circumferentially relative to the first outer conductor.

[0023] Furthermore, the outer end face of the anti-rotation bump near the second outer conductor abuts against the ring platform to limit the insulator.

[0024] Furthermore, the first sealant is used to fill the gap between the mounting hole and the second outer conductor, and the second sealant is used to fill the gap between the inner wall of the insertion portion of the first outer conductor and the center terminal.

[0025] Furthermore, a limiting platform is provided between the insertion part and the mounting part, and the limiting platform is used for installation stop when the mounting part is installed in the mounting hole.

[0026] Furthermore, a method for manufacturing the aforementioned FAKRA angled vehicle camera connector includes the following steps:

[0027] Step 1: Center terminal punching and forming. A center terminal with a strip is formed by one-time stamping on a metal plate, forming a center terminal strip, and then the center terminal strip is electroplated.

[0028] Step 2: Injection molding to form terminal assemblies. The electroplated center terminal strip is cut into segments, each segment containing multiple center terminals. The cut strip segments are placed into the injection mold, so that the center terminals are injection molded with an insulator, resulting in multiple terminal assemblies with the strip.

[0029] Step 3: Cutting and separating. Place multiple terminal assemblies with material strips into a cutting fixture and cut and separate them to obtain individual terminal assemblies.

[0030] Step 4: Assemble the terminal assembly. Fix the plug end of the first outer conductor in the fixture, and then install the individual terminal assembly from the opening of the mounting part of the first outer conductor and install it into the first cavity along the axis of the plug end.

[0031] Step 5: Assemble the second outer conductor, then coaxially install the second outer conductor with the mounting part of the first outer conductor. Use a riveting and dotting process to rivet the inner edge of the end face of the mounting part to fix the second outer conductor and the first outer conductor to form a plug-in assembly.

[0032] Step 6: Assemble the metal back cover, then insert and fix the mounting part of the plug-in assembly perpendicular to the mounting panel into the mounting hole of the metal back cover, with the end of the mounting part extending into the receiving cavity. Use a riveting and dotting process to rivet the outer edge of the end face of the mounting part to fix the metal back cover to the plug-in assembly.

[0033] Step 7: Sealing process. Fill the gap between the mounting hole and the second outer conductor with a first sealant, and fill the gap between the inner wall of the insertion part of the first outer conductor and the center terminal with a second sealant.

[0034] Compared with the prior art, the beneficial effects of the FAKRA angled vehicle camera connector and its manufacturing method provided by the present invention are as follows:

[0035] 1. Facilitates installation in confined spaces, improving space utilization.

[0036] In use, the camera connector's plug end connects to the wire harness connector, and the back cover connects to the camera. This invention transforms the plug end into an angled extension along the back cover, so the mating connector that connects to the angled camera connector along the plugging direction is an angled plug, freeing up the thickness space behind the camera. This allows it to be installed in narrow areas that previously could not accommodate a vertical camera connector, such as inside the rearview mirror housing, the inner layer of the bumper, or near the license plate light. The angled connector moves the wire end connector body that it mates with to the side of the camera, improving the utilization rate of the space behind the camera. This provides greater freedom for terminal shape design and camera layout optimization.

[0037] 2. Excellent electromagnetic shielding and heat dissipation performance.

[0038] The first and second outer conductors of this invention are fitted together to form a circumferentially continuous cylindrical shielding layer. Combined with a tight fit with the metal back cover, this creates a closed cavity, effectively suppressing electromagnetic leakage and preventing external electromagnetic interference from entering the connector. Furthermore, this invention eliminates the need for a plastic outer shell, and the metal back cover has a high thermal conductivity and a large surface area, allowing heat to be conducted through the metal back cover, forming an efficient heat dissipation channel. Therefore, the angled camera connector provided by this invention possesses excellent electromagnetic shielding performance and efficient heat dissipation performance, fully meeting the comprehensive performance requirements of high-pixel cameras for heat dissipation, shielding, and structural strength.

[0039] 3. The use of riveting for fixing significantly improves connection reliability.

[0040] Unlike the prior art which relies on a plastic shell for fixation, this invention directly and mechanically fixes the metal back cover, the first outer conductor, and the second outer conductor by riveting and dotting. Therefore, under repeated insertion and removal and vibration environments, the problems of plastic shell deformation and fixing component failure are avoided, and the connection stability is effectively guaranteed.

[0041] 4. Waterproofing and sealing effects can be achieved by using two seals.

[0042] The connector structure of this invention only requires sealant to be applied at two locations: inside the insertion port and inside the accommodating cavity, to achieve waterproof and sealing effects. It eliminates the need to apply sealant at multiple locations such as the mating surface and the split surface of the plastic shell, reducing the number of sealing nodes. This not only effectively reduces the probability of overall waterproof failure of the connector due to aging or damage of any node, but also avoids the problem of the preset sealing state being destroyed due to deformation of the plastic shell, resulting in more stable and reliable waterproof performance.

[0043] 5. Easy to assemble and readily automates production.

[0044] The connector of this invention has simple components, fewer assembly steps, and convenient processing, which helps to reduce the probability of assembly errors. The sealing process is set at the last step of the entire process, avoiding the wasted time of waiting for the sealant to cure during assembly, effectively improving assembly efficiency, and is suitable for automated assembly lines.

[0063] The accompanying drawings, which form part of this application, are used to provide a further understanding of the invention. The illustrative embodiments of the invention and their descriptions are used to explain the invention and do not constitute an improper limitation of the invention. Detailed Implementation

[0064] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application. Furthermore, the terms "first," "second," etc., in the specification and claims are used to distinguish similar objects and are not used to describe a specific order or sequence.

[0065] refer to Figures 1 to 4 A FAKRA angled vehicle camera connector, comprising:

[0066] The metal back cover 100 has a mounting panel 101, a back cover sidewall, a mounting hole 102 opened on the mounting panel 101, and an accommodating cavity 103 formed by the mounting panel 101 and the back cover sidewall.

[0067] Terminal assembly 200 includes a center terminal 201 and an insulator 202 sleeved on the outside of the center terminal 201;

[0068] The first outer conductor 300 is an integral metal structure, including a mounting part 303, a plug-in part 302, and a first cavity 301 formed inside the first outer conductor 300 for accommodating the terminal assembly 200. The mounting part 303 is also provided with a clearance groove 306, which is formed along the axis of the plug-in part 302 and communicates with the first cavity 301, so that the terminal assembly 200 can be installed into the first cavity 301 along the axis of the plug-in part 302. The plug-in part 302 has an integrally formed FAKRA connector (FAKRA is a standard connector for radio frequency connectors) for mating with a mating connector on its outer side. The axis of the plug-in part 302 and the axis of the mounting part 303 form a preset angle. The mounting part 303 is perpendicular to the mounting panel 101 and is plugged into and fixed in the mounting hole 102. The axis of the plug-in part 302 and the mounting panel 101 form a non-perpendicular angle.

[0069] The second outer conductor 400 has a hollow cylindrical metal structure and a second cavity 401 inside for the terminal assembly 200 to pass through and fit. The second outer conductor 400 is coaxially and fixedly connected to the mounting part 303 of the first outer conductor 300. The second outer conductor 400 is coaxially installed in the mounting part 303, and the second outer conductor 400 and the first outer conductor 300 together form a circumferentially continuous cylindrical shielding structure.

[0070] The sealant includes a first sealant 501 filled in the accommodating cavity 103 of the metal back cover 100 and a second sealant 502 filled in the first cavity 301 of the first outer conductor 300.

[0071] The end of the mounting part 303 is riveted to the second outer conductor 400 and the metal back cover 100 to form a riveting part 304, so that the first outer conductor 300, the second outer conductor 400 and the metal back cover 100 are fixedly connected to form an integral structure.

[0072] The non-perpendicular angle design of this invention provides a secondary angle reinforcement effect. The insertion portion 302 of the first outer conductor 300 and the vertically mounted mounting portion 303 form a first-level angle constraint, thus fixing the tilt angle of the insertion portion 302 to a preset angle value. The second outer conductor 400 is mounted on top of the first outer conductor 300, further fixing the same preset angle. By repeatedly locking the same angle twice, the stability of the connector's non-perpendicular angle is significantly enhanced, effectively preventing tilt angle deformation during use and ensuring performance stability in confined spaces or specific angle installation scenarios.

[0073] The mounting part 303 is mounted perpendicularly to the mounting hole 102 and is interference-fitted. In addition, the angle formed between the axis of the insertion part 302 and the mounting panel 101 is an acute angle.

[0074] Furthermore, while ensuring reliable fixation between the connector and the mounting panel, the center of the mounting hole 102 is offset from the geometric center of the mounting panel 101 and offset towards the side wall of the metal back cover 100. After the connector is installed, the projection of the insertion part 302 is located outside the mounting panel 101 when projected perpendicularly to the mounting panel 101. This design facilitates insertion with the wire end connector and can also optimize stress distribution.

[0075] Specifically, the first outer conductor 300 is integrally die-cast and has no groove or limiting installation mechanism on its outer surface. It is installed only through the end port of the first outer conductor 300. The center terminal 201 is integrally formed in a bent shape, and the first cavity 301 can accommodate the inflection point of the center terminal 201 so that the waterproof sealant can be arranged to achieve better waterproof and shielding effects.

[0076] In normal use, the camera connector's plug end connects to the wire harness connector, and the back cover connects to the camera. Since the plugging direction of this application no longer extends vertically along the metal back cover 100, but instead extends obliquely relative to the metal back cover 100, the mating connector that connects to the angled camera connector along the plugging direction is an oblique plugging, which frees up the thickness space behind the camera. This allows it to be installed in narrow areas that previously could not accommodate a vertical camera connector, such as inside the rearview mirror housing, the inner layer of the bumper, or near the license plate light. The angled connector moves the wire end connector body that it mates with to the side of the camera, improving the utilization rate of the space behind the camera. This provides greater freedom for terminal shape design and camera layout optimization.

[0077] Compared to Figure 10 and Figure 11 The camera connector shown in the background art, and the angled vehicle camera connector provided by this invention, employs a first outer conductor 300 and a second outer conductor 400 sleeved together to form a circumferentially complete cylindrical shielding layer. Combined with a tight fit with the metal back cover 100, the entire shielding structure forms a closed cavity, effectively suppressing external electromagnetic interference and preventing electromagnetic radiation leakage from the internal circuitry, ensuring the signal integrity and stability of the camera module in high-frequency operating environments. Furthermore, this invention does not use a plastic shell, and the metal back cover 100 has a high thermal conductivity and a large heat dissipation area, quickly conducting the heat generated by the camera module to the external environment, avoiding localized overheating, thereby extending device lifespan and maintaining image quality. Therefore, the angled camera connector provided by this invention possesses excellent electromagnetic shielding performance and efficient heat dissipation performance.

[0078] Traditional plastic housings are typically only suitable for cameras with one or two megapixels. Because plastic has poor thermal conductivity, heat easily accumulates, causing the camera to overheat during continuous operation, thus affecting image clarity and sensor reliability. Therefore, the angled automotive camera connector provided in this application fully meets the comprehensive performance requirements of high-resolution cameras for heat dissipation, shielding, and structural strength.

[0079] In addition, the rivet part 304 enables the connector to form a permanent, vibration-resistant mechanical connection without the need for additional fasteners or adhesives, and can withstand greater insertion and extraction forces and maintain a stable connection.

[0080] Meanwhile, the components of the camera connector in this application are simpler. The structure and installation method of the first outer conductor 300, the second outer conductor 400, and the metal back cover 100 allow the connector to achieve a sealing and waterproof effect with only two sealing and waterproof parts. This meets the needs of scenarios such as narrow spaces and installation at specific angles.

[0081] refer to Figure 3 In this embodiment, the insulator 202 is integrally injection molded and includes an inclined body 2021 and an upright end 2022 partially connected to the inclined body 2021. A recess 2023 is formed at the connection between the inclined body 2021 and the upright end 2022, and the inclined body 2021 has a receiving surface 2024 perpendicular to the axis of the insertion portion 302 at the recess 2023 to receive the external pushing force to insert the terminal assembly 200 into a predetermined position in the first cavity 301. Furthermore, the insulator 202 is also provided with an annular recess 2027, which reduces the friction during the installation of the terminal assembly 200, facilitating installation. In addition, the annular recess 2027 can reduce the effective dielectric constant of the insulator 202 by introducing air, thereby optimizing the impedance matching performance of the connector and reducing high-frequency signal transmission loss.

[0082] refer to Figure 1 , Figure 4 and Figure 9 In this embodiment, an annular platform 402 is provided on the outer side wall of one end of the second outer conductor 400, and an annular groove 305 communicating with the first cavity 301 is provided on the inner wall of the mounting part 303. The annular platform 402 of the second outer conductor 400 is coaxially mounted in the annular groove 305 of the first outer conductor 300. This achieves the positioning and installation between the first outer conductor 300 and the second outer conductor 400, ensuring the space requirement for coaxial installation of the center terminal 201, thereby keeping the center terminal 201 aligned with the axis throughout the transmission path, effectively reducing signal reflection and loss, and improving the high-frequency transmission performance of the connector.

[0083] refer to Figure 4 , Figure 6 and Figure 7In this embodiment, the mounting part 303 passes through the mounting hole 102, the inner edge of the end face of the mounting part 303 is riveted to the second outer conductor 400 to form a first riveting part 304a, and the outer edge of the end face of the mounting part 303 is riveted to the metal back cover 100 to form a second riveting part 304b.

[0084] Specifically, the riveting part 304 formed on the inner edge of the end face of the mounting part 303 acts on both the end face of the mounting part 303 and the ring platform 402, thereby fixing the first outer conductor 300 and the second outer conductor 400. The riveting part 304 formed on the outer edge of the end face of the mounting part 303 acts on both the end face of the mounting part 303 and the inner side of the mounting hole 102, thereby fixing the first outer conductor 300 to the metal back cover 100. The riveting points on the inner and outer edges are arranged at intervals.

[0085] The formation of the rivet part 304 can significantly improve the connection reliability of the connector and effectively increase the insertion and extraction force that the connector can withstand, specifically enabling the connector to withstand an insertion and extraction force of at least 110N.

[0086] Furthermore, when the first outer conductor 300, the second outer conductor 400, and the metal back cover 100 are installed, the end face of the mounting part 303 of the first outer conductor 300 protrudes slightly compared to the end face of the ring platform 402 of the second outer conductor 400 and the inner end face of the mounting hole 102, which facilitates the implementation of the riveting and dotting process.

[0087] refer to Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 9 In this embodiment, a protrusion 403 is provided on the outer end face of the ring platform 402 of the second outer conductor 400, and a limiting groove 3051 communicating with the ring groove 305 is provided on the inner wall of the mounting part 303. The protrusion 403 and the limiting groove 3051 cooperate to form a limiting structure to prevent the insulator 202 from coming out of the second outer conductor 400. At the same time, a preset angle is formed between the insertion part 302 of the first outer conductor 300 and the second outer conductor 400.

[0088] In the actual installation process, the first outer conductor 300 is installed with the second outer conductor 400 first, and then the metal back cover 100 is installed. By ensuring that the first outer conductor 300 and the second outer conductor 400 are installed at a preset angle in advance, it is ensured that the axis of the plug portion 302 of the first outer conductor 300 forms a specific angle that is not perpendicular to the mounting panel 101, thus meeting the needs of the actual scenario.

[0089] refer to Figure 3 , Figure 4 and Figure 5In this embodiment, the inner wall of the mounting part 303 is also provided with an anti-rotation groove 3052, and the insulator 202 is provided with an anti-rotation protrusion 2025. The anti-rotation groove 3052 and the anti-rotation protrusion 2025 are matched to limit the circumferential rotation of the insulator 202 relative to the first outer conductor 300, so that the terminal assembly 200 and the first outer conductor 300 are reliably fixed, which facilitates the accurate assembly of the terminal assembly 200 and the first outer conductor 300.

[0090] Furthermore, both the anti-rotation groove 3052 and the limiting groove 3051 are connected to the annular groove 305, and the anti-rotation groove 3052 and the limiting groove 3051 are arranged opposite to each other, so that the force distribution between the limiting structures of the terminal assembly 200 is balanced.

[0091] refer to Figure 1 , Figure 3 and Figure 9 In this embodiment, the outer end face of the anti-rotation bump 2025 near the second outer conductor 400 abuts against the ring platform 402, further limiting the insulator 202.

[0092] refer to Figure 8 and Figure 9 In this embodiment, a first sealant 501 is provided in the gap between the mounting hole 102 and the second outer conductor 400, and a second sealant 502 is provided in the gap between the inner wall of the insertion part 302 of the first outer conductor 300 and the center terminal 201.

[0093] The first sealant 501 is tightly adhered to the outer wall of the second outer conductor 400 and completely covers the riveting part 304; the second sealant 502 is tightly adhered to the inner wall of the insertion part 302 of the first outer conductor 300 and the outer wall of the center terminal 201 that protrudes from the second sealant 502.

[0094] By using the first sealant 501 and the second sealant 502 at the two locations mentioned above, the overall waterproofing and sealing effect of the connector can be achieved. At the same time, the first sealant 501 can further fix the first end of the insulator 202, and the second sealant 502 can further fix the tail end of the insulator 202, and prevent metal debris from being generated in the riveting part 304, thereby enhancing the connection reliability of the riveting part 304.

[0095] Continue to refer to Figure 1 , Figure 3 and Figure 9 In this embodiment, a limiting platform 307 is also provided between the plug-in part 302 and the mounting part 303. When the mounting part 303 of the first outer conductor 300 is installed in the mounting hole 102, the limiting platform 307 is used for installation stop.

[0096] The present invention also provides a method for manufacturing the above-mentioned angled vehicle camera connector, comprising the following steps:

[0097] Step 1: The center terminal 201 is punched and formed. The center terminal 201 with material strip is formed by punching and forming in one step on the metal plate, forming the center terminal 201 material strip, and the center terminal 201 material strip is electroplated.

[0098] Step 2: Injection molding to form terminal assembly 200. Cut the electroplated center terminal 201 strip into segments. Each strip contains multiple center terminals 201. Place the cut strip segments into the injection mold so that the center terminals 201 are externally injection molded with insulators 202, thus obtaining multiple terminal assemblies 200 with strips.

[0099] Specifically, the insulator 202 has a radially penetrating through hole 2026. During the injection molding process of the insulator 202, the center terminal 201 can be clamped or fixed at the through hole 2026 to prevent the center terminal 201 from shaking or deforming during the injection molding process.

[0100] Step 3: Cutting and separating. Place the multiple terminal assemblies 200 with the material strip into the cutting fixture, and cut and separate them to obtain a single terminal assembly 200.

[0101] Step 4: Assemble the terminal assembly. Fix the plug-in end of the first outer conductor 300 in the fixture, and then install the single terminal assembly 200 from the opening of the mounting portion 303 of the first outer conductor 300 and install it into the first cavity 301 along the axis of the plug-in portion 302. For details, please refer to [reference needed]. Figure 5 ;

[0102] Step 5: Assemble the second outer conductor, then coaxially mount the second outer conductor 400 to the mounting portion 303 of the first outer conductor 300. Rivet the inner edge of the end face of the mounting portion 303 using a riveting and dotting process to fix the second outer conductor 400 and the first outer conductor 300 together, forming a plug-in assembly. See the attached document for details. Figure 6 ;

[0103] Step Six: Assemble the metal back cover, then insert and fix the mounting part 303 of the plug-in assembly perpendicular to the mounting panel 101 into the mounting hole 102 of the metal back cover 100, with the end of the mounting part 303 extending into the receiving cavity 103. Use a riveting and dotting process to rivet the outer edge of the end face of the mounting part 303, thus fixing the metal back cover 100 to the plug-in assembly. For details, please refer to... Figure 7 ;

[0104] Step 7: Sealing process. Fill the gap between the mounting hole 102 and the second outer conductor 400 with first sealant 501, and fill the gap between the inner wall of the insertion part 302 of the first outer conductor 300 and the center terminal 201 with second sealant 502. See the following for details. Figure 8 .

[0105] refer to Figure 8 and Figure 9 In this embodiment, a sealing platform 104 is also provided in the accommodating cavity 103. The sealing platform 104 is located on the outer ring of the mounting hole 102 and is used to accommodate the first sealant 501.

[0106] Furthermore, the specific sealing process involves dispensing. By setting up the sealing platform 104, the flow range and filling height of the sealant can be precisely controlled. This ensures that the sealant is confined within the sealing platform 104 during dispensing, preventing leakage and runoff. Simultaneously, the sealing platform 104 provides a stable containment space and adhesion surface for the cured sealant, ensuring that the sealant is not prone to peeling or cracking during long-term use, thus significantly improving the stability and reliability of the sealing connection.

[0107] The manufacturing method of the angled vehicle camera connector provided in this embodiment has simple and convenient installation steps, which greatly reduces the probability of assembly errors. The connector has simple components and the sealing process is placed after the process, which significantly shortens the installation time and effectively improves the connector assembly efficiency.

[0108] The above embodiments are preferred embodiments of the present invention, but not all embodiments. Any equivalent changes to the technical solutions of the invention made by those skilled in the art after reading the specification of the present invention are covered by the present invention.
