Description

Technical Field

[0001] This utility model relates to the field of conductive connection technology, and in particular to a split-type camera connector rear shell assembly. Background Technology

[0002] With the continuous development of automotive intelligence and connectivity technologies, in-vehicle cameras play a crucial role in improving driving safety and enhancing user experience. As a key component connecting in-vehicle cameras to other electronic systems, the design and manufacturing quality of camera connectors directly impacts overall vehicle performance and consumer satisfaction. Currently, common camera rear housing assemblies on the market typically employ a method of forging an aluminum housing and a FAKRA connector into a single, integral part to reduce quality risks associated with multi-stage assembly. However, this simplistic design approach also has significant shortcomings, hindering industry development to some extent.

[0003] Firstly, while forging the aluminum housing and FAKRA connector into a single unit reduces structural loosening and sealing issues, it also sacrifices the rigidity of the FAKRA connector. This design makes the connector more susceptible to deformation or damage under mechanical stresses such as vibration and impact, affecting the stable connection and normal operation of the camera. Furthermore, since the FAKRA connector itself has various snap-fit ​​sizes, the current integral forging method requires the manufacture of corresponding housing forging dies for different snap-fit ​​sizes. This not only complicates the production process and increases manufacturing difficulty but also significantly increases production and development costs. Therefore, a new design improvement is needed for the existing camera connector. Utility Model Content

This improves the performance of the camera connector and enhances its adaptability to complex application environments, providing users with greater reliability and a better user experience.

[0027] A method for manufacturing a split-type camera connector rear shell assembly includes the following steps: Phase 1, Pre-assembly of zinc alloy plug 2: Step S1.1, Oriented insertion of electrical terminal 33: The electrical terminal 33 is oriented and conveyed by a vibratory feeder, and inserted into the insulator 31 and the seal 32 by a mechanical arm to form the electrical assembly 3; Step S1.2, The polytetrafluoroethylene seal 32 is shrunk by 0.05mm by liquid nitrogen freezing and then installed into the sealing step 251, and springs back at room temperature to form an interference fit; Step S1.3, Press-fitting of insulator 31: The insulator 31 is shrunk by low temperature freezing and then pressed into the electrical fixing part 25 of the zinc alloy plug 2; Phase 2, riveting and integration of aluminum shell 1: Step S2.1, interference fit assembly: insert the assembly fixing end 21 of zinc alloy plug 2 into the mating fixing groove 12, and the interference fit point 214 interferes with the interference fit groove 122; Step S2.2, riveting forming: riveting groove 231 is formed on one side of the fixed rivet point 23 by riveting with a riveting head, so that the fixed rivet point 23 is embedded into the fixed inclined surface 123, thereby making the zinc alloy plug 2 and aluminum shell 1 riveted together to form an integral unit; Phase 3, Encapsulation and Reinforcement: Step S3.1, Vacuum Injection: Inject epoxy resin into the filling part under negative pressure; Step S3.2, UV Curing: Cure the adhesive by irradiation with a UV lamp.

[0028] In Phase 1, the pre-assembly of the zinc alloy plug 2 ensures the stability and sealing of the electrical connection through a series of meticulous operations. In step S1.1, the vibratory feeder orientation conveying and robotic arm clamping insertion technology of the power connection terminal 33 improves the degree of automation and assembly accuracy, reduces human error, and thus ensures the consistency and reliability of the power connection assembly 3. In step S1.2, the interference fit design of the PTFE seal 32 after liquid nitrogen freezing shrinkage ensures a seamless connection between the seal 32 and its mounting part, effectively improving waterproof and dustproof performance. In step S1.3, the low-temperature freezing of the insulator 31 and its press-fitting to the zinc alloy plug 2 further enhances the electrical insulation performance of the connector, providing a foundation for subsequent high-quality signal transmission.

[0029] In Phase Two, during the riveting and integration of the aluminum shell 1, a robust connection between the zinc alloy plug 2 and the aluminum shell 1 is achieved through interference fit and riveting forming. The interference fit ensures a tight fit of the assembly fixing end 21, increasing the stability of the mechanical connection. The riveting forming technology, by riveting the fixing groove 231 into the fixed riveting point 23, integrates the zinc alloy plug 2 and the aluminum shell 1 into a single structure. This improves the connector's vibration and impact resistance, adapting it to the complex environment of vehicle operation.

[0030] Finally, the third stage of encapsulation reinforcement further enhances the connector's protective performance through vacuum injection and UV curing. Vacuum injection technology ensures that the epoxy resin completely fills the voids within the component, preventing air bubbles and enhancing waterproofing and moisture resistance. UV curing rapidly hardens the adhesive, improving production efficiency while forming a robust protective layer, further improving the connector's durability and environmental adaptability.

[0031] This invention, through precise operating procedures and innovative manufacturing technology, endows the vehicle-mounted camera connector with excellent mechanical strength, electrical performance, and environmental tolerance, ensuring its long-term stable operation under harsh vehicle conditions. The manufacturing method not only improves product quality but also significantly reduces failure rates and maintenance costs, providing users with a more reliable experience.

[0032] Step 1.3 In the press-fitting of insulator 31, the nano-coating pretreatment is performed: the surface of insulator 31 is sandblasted and coated with a nano-silica coating. The thickness of the nano-silica coating is 2μm, which reduces the coefficient of friction. In this embodiment, the sandblasting and the application of the nano-silica coating significantly improve the assembly quality and performance of insulator 31 and zinc alloy plug 2. Sandblasting makes the surface of insulator 31 more uniform and effectively removes tiny impurities, providing a good foundation for coating adhesion. The 2μm thickness of the nano-silica coating reduces the coefficient of friction, making it easier for insulator 31 to be embedded into the electrical fixing part 25 of zinc alloy plug 2 after low-temperature freezing. This enhances the smoothness of the assembly process and improves the wear resistance of insulator 31, ensuring stability and reliability during long-term use, thereby improving the overall durability and performance of the connector.

[0033] In step S3.1, the vacuum injection process enhances adhesive penetration through laser microtexturing of the inner wall of the mating fixing groove 12, creating pits with a diameter of 80 μm and a density of 200 pits / mm². Adhesive modified with 0.5% carbon nanotubes is then injected. In this embodiment, the adhesive penetration enhancement process, achieved through laser microtexturing of the inner wall of the mating fixing groove 12 and the use of carbon nanotube-modified adhesive, significantly improves the adhesion and penetration of the adhesive. The laser microtexturing technology creates dense pits on the inner wall, increasing the surface area and mechanical locking effect, allowing for better filling and curing of the adhesive. The addition of 0.5% carbon nanotubes to the modified adhesive improves thermal conductivity and electrical properties, while also enhancing structural strength. This ensures uniform distribution and firm adhesion of the adhesive within the fixing groove, improving the connector's leak-proof performance and environmental resistance, and extending its service life and reliability.

[0034] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
