One end of the third anti-retraction part 27 abuts against the wall surface of the positioning post 95 of the locking member 9, thereby preventing the rear metal shell 2 from moving backward, thus making the structure of the automotive Ethernet connector 100 of this utility model more stable. The top end of the positioning post 95 of the locking member 9 abuts against the outer surface of the lower sidewall of the socket 23 of the rear metal shell 2.

[0087] As described above, the automotive Ethernet connector 100 of this utility model, through an innovative structural design, forms a gap 101 between the front end of the sleeve portion 23 of the rear metal shell 2 and the rear end of the inward portion 12 and the extension portion 13 of the front metal shell 1. The rear ring portion 32 of the elastic metal shell 3 is fixed in the gap 101 and contacts the inner surface of the front end of the sleeve portion 23 of the rear metal shell 2. 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.
