Description

Technical Field

[0001] This utility model relates to the field of new energy connector technology, specifically to an Avita E15DK5 antenna device. Background Technology

[0002] The central control connector in new energy vehicles is a key component used to connect the central control system (such as displays, control modules, etc.) with other electronic devices or wiring harnesses in the vehicle. It enables reliable transmission of current or signals through a physical interface, ensuring efficient communication and data exchange between the central control system and various vehicle components.

[0003] A search revealed a new energy connector disclosed in Chinese utility model patent CN222300945U. This utility model patent includes a main body with a sealing ring, a retaining edge, and a protrusion. The main body and the retaining edge are detachably connected. Side platforms are provided on both sides of the main body corresponding to the protrusion. A groove is formed between the upper surface of the side platform and the side wall of the protrusion. The sealing ring includes an extension that fits onto the protrusion and extends to the groove. The sealing ring is fitted onto the protrusion, and a retaining block is provided on the protrusion. The retaining block can be engaged in the groove and forms a clamping effect with the side platform on the extension. Addressing the shortcomings of existing technologies, this utility model provides a new energy connector that facilitates sealing ring installation, improves the phenomenon of sealing ring detachment during airtightness and mating in traditional connectors, effectively increases product utilization, and reduces product production costs.

[0004] Traditional connectors, due to their loose structure, insufficient electromagnetic shielding performance, limited mating life, and poor stability, are no longer able to meet the comprehensive requirements of new energy vehicles for compact design, efficient signal transmission, high reliability, and environmental resistance. For example, existing connectors are prone to signal interference and unstable contact resistance under high-voltage environments, leading to communication interruptions or data errors between the central control system and vehicle components. At the same time, the limitations of traditional materials in terms of heat resistance, chemical resistance, and mechanical strength further limit the service life of connectors under harsh working conditions. Therefore, an Avita E15DK5 antenna device is proposed to solve the above problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 An Avita E15DK5 antenna device in this embodiment includes a front shell 1, a rear cover 2 fixedly installed on the top of the front shell 1, a plug 3 fixedly installed on the left end of the front shell 1, a plastic part 4 fixedly installed inside the front shell 1, a pin 5 inserted into the plastic part 4, a fisheye through hole 6 opened inside the pin 5, and heat dissipation through holes 7 opened on both the front and rear sides of the front shell 1, with heat dissipation capsules 8 fixedly installed inside the heat dissipation through holes 7.

[0021] exist Figure 2In the process, the pin 5 adopts a copper-nickel-silicon alloy fisheye structure with a fisheye through hole 6 inside. It achieves a solderless press-fit connection with the PCB board through mechanical pressure. In specific implementation, after the pin 5 is inserted into the through hole of the PCB board, the fisheye through hole 6 is deformed by pressure to form an elastic contact, ensuring that the contact resistance is ≤5mΩ and the stability is better than traditional soldering.

[0022] exist Figure 3 In the middle, heat dissipation holes 7 are opened on both the front and rear sides of the front shell 1, and polymethyl methacrylate (PMMA) heat dissipation capsules 8 are embedded inside. The capsules are filled with paraffin phase change material (PCM). When the working temperature of the antenna device rises to 45°C, the paraffin absorbs heat and melts, absorbing 120J / g of heat, reducing the internal temperature rise by 10-15°C. When the temperature drops to 35°C, the paraffin solidifies and releases heat, forming a dynamic thermal equilibrium. The heat dissipation capsules 8 are tightly attached to the inner wall of the heat dissipation holes 7 through the matrix material, and the thermal conductivity is increased to 2W / (m·K), which is 4 times more efficient than air convection heat dissipation.

[0023] exist Figure 2 In the middle, the plastic part 4 is fixed inside the front shell 1 by an integrated embedding process. The plastic part 4 is made of PBT + 30% glass fiber reinforced material with a heat distortion temperature of 220℃ and solderability that meets the requirements of lead-free soldering process. The copper-nickel-silicon alloy pin 5 is directly pressed into the hole of the plastic part 4. The hole-shaft fit clearance is controlled at 0.02-0.05mm to form an interference fit. This structure increases the vibration resistance of the pin 5 to 15g vibration frequency of 10-2000Hz, which is 50% higher than the traditional welding structure. It effectively avoids contact loosening caused by vibration during vehicle operation. At the same time, the plastic part 4 and the front shell 1 are fixed by a snap-fit ​​structure, which shortens the assembly time to 10 seconds / piece, making it suitable for mass production on automated production lines.

[0024] During implementation, follow these steps: When in use, connect the front shell 1 and the rear cover 2 with snaps or threads to ensure a tight seal. Align the plug 3 with the corresponding interface of the new energy vehicle's central control system, gently press it in until it is locked, and confirm that the electrical connection is stable. Check whether the fisheye through-hole 6 of the internal pin 5 of the plastic part 4 is aligned with the PCB board pads to avoid loose connections. After running continuously for 1 hour, use an infrared thermometer to detect the surface temperature of the front shell 1. If the temperature exceeds the heat resistance limit of polymethyl methacrylate (PMMA) material by about 80°C, check whether the paraffin phase change inside the heat dissipation capsule 8 is complete and the liquid state is normal.

[0025] In summary, the Avita E15DK5 antenna device features a front shell 1 and a rear cover 2 made of PBT material, which combines high strength, high rigidity, and excellent electrical insulation to ensure stable operation under high temperature and complex chemical environments. The pins 5 are made of copper-nickel-silicon alloy, which has superior electrical and thermal conductivity compared to traditional brass, significantly reducing contact resistance and improving durability. Internally, the fisheye through-hole structure 6 and integrated embedded plastic part 4 achieve a weld-free press-fit connection, simplifying the production process while improving mechanical stability and vibration resistance, preventing the risk of poor soldering and short circuits. The heat dissipation through-hole 7 embeds a polymethyl methacrylate-based paraffin heat dissipation capsule 8, effectively enhancing heat dissipation. Thermal management efficiency ensures long-term operational reliability and solves the problems of traditional connectors, such as loose structure, insufficient electromagnetic shielding performance, limited mating life, and poor stability. These issues make it difficult to meet the comprehensive requirements of new energy vehicles for compact design, efficient signal transmission, high reliability, and environmental resistance. For example, existing connectors are prone to signal interference and unstable contact resistance under high-voltage environments, leading to communication interruptions or data errors between the central control system and vehicle components. At the same time, the limitations of traditional materials in terms of heat resistance, chemical resistance, and mechanical strength further limit the service life of connectors under harsh working conditions.
