Description

Technical Field

[0001] This utility model relates to an automotive Ethernet connector, and more particularly to an automotive Ethernet connector with better electromagnetic interference protection and improved high-frequency signal transmission stability. Background Technology

[0002] With the rapid development of the automotive industry, various functional components and parts in automobiles are constantly evolving towards intelligence, refinement, and reliability, which also places higher demands on the structural design, appearance design, and materials of automotive connectors.

[0003] Chinese patent application CN115336118A discloses a "cable element for terminating a cable," comprising a cable element mating end and a cable element receiving end. A metal housing is positioned close to the cable element mating end. The metal housing has a mating contact engagement portion. A housing made of dielectric material is located within the metal housing. A resilient contact arm is disposed on the mating contact engagement portion of the metal housing. The resilient contact arm extends from close to the cable element mating end. The front end of the resilient contact arm is positioned close to the cable element mating end and cooperates with the protective portion of the cable element to prevent the front end of the resilient contact arm from being impacted when the cable element mates with the mating element.

[0004] However, when transmitting high-frequency signals, the internal structure of the connector can cause electromagnetic field resonance, resulting in particularly poor high-frequency characteristics in certain frequency bands. Combined with impedance mismatch, this leads to increased insertion and reflection losses, affecting crosstalk. This phenomenon is more severe at high frequencies, further impacting the signal quality transmitted by the electrical connector. Furthermore, the flexible contact arm is integrally stamped with the metal housing, and it is formed by bending a metal sheet into a ring. The aforementioned manufacturing method for the flexible contact arm requires extremely high precision, thus hindering effective improvement in product yield.

[0005] Therefore, it is necessary to provide an automotive Ethernet connector with better electromagnetic interference protection and improved high-frequency signal transmission stability. Furthermore, automotive Ethernet connectors offer simple manufacturing methods and high production yields. Utility Model Content

At the same time, the rear ring portion 32 of the elastic metal shell 3 contacts the outer surface of the extension portion 13 of the front metal shell 1. The front surfaces of the upper and lower ends of the sleeve portion 63 are provided with several protrusions 65. The several protrusions 65 contact the inner surface of the rear end of the first main body portion 11 of the front metal shell 1. The positioning post 95 extends upward from the middle of the upper surface of the plate portion 91 of the locking member 9. The positioning post 95 is fixed inside the assembly hole 84 of the outer shell 8, and the top end of the positioning post 95 protrudes from the assembly hole 84 of the outer shell 8 and is fixed inside the positioning hole 24 of the rear metal shell 2 to achieve positioning and fixation of the locking member 9, the outer shell 8 and the rear metal shell 2. The top end of the positioning post 95 abuts against the outer surface of the lower side wall of the first main body 11 of the front metal shell 1, thereby preventing the rear metal shell 2 from moving backward. The middle of the positioning post 95 is recessed inward to form the positioning groove 96, and the sealing ring 97 is disposed at the position of the positioning groove 96. The sealing ring 97 is tightly fitted with the assembly hole 84 of the outer shell 8 to achieve the effect of sealing and waterproofing. Therefore, the automotive Ethernet connector 100 of this utility model has better electromagnetic interference protection, improved high-frequency signal transmission stability, waterproofing and structural stability.
