The front end of the insulating body 1 is surrounded by four walls to form a trapezoidal insertion space 11 for accommodating a mating connector (not shown). A plurality of terminal grooves 12 are provided on the upper and lower walls of the insulating body 1 and communicate with the insertion space 11 for receiving the conductive terminals 2 . Each conductive terminal 2 is inserted from the rear end to the front end of the insulating housing 1 along the terminal slot 12 , and extends inward into the insertion space 11 for electrical contact with the mating connector. The insulating housing 1 further includes a body portion 14 , an extension portion 15 extending backward from the body portion 14 , and a pair of hooks 16 located at a rear end of the extension portion 15 . A step 13 is formed between the main body portion 14 and the extension portion 15 .

The upper and lower surfaces of the printed circuit board 3 have several conductive sheets 31 .

The casing 5 is made of metal material, zinc alloy in this embodiment, and includes a front casing 51 and a rear casing 52 installed at the rear of the front casing 51 . The front housing 51 includes a frame-shaped base 511 matching the outline of the insulating body 1, a housing space 510 surrounded by the frame-shaped base 511, a docking portion 513 extending backward from the base 511, and a pair of sockets located at the rear end of the docking portion 513. Notch 514. A step (not shown) is formed between the base portion 511 and the docking portion 513 .

The rear housing 52 is integrally formed, and has a receiving space 520 for receiving the stress relief element 6 and the grounding ring 7 , and a through hole 521 located at the rear end and communicating with the receiving groove 520 .

The grounding ring 7 is stamped and formed of metal material, which has a fixed ring 71 with the same shape as the cable 4, a pair of elastic pieces 72 separated from the fixed ring 71 and opened outwards, and formed by expanding the elastic pieces 72 outwards. Notch 73.

When assembled, the conductive terminal 2 is inserted into the terminal groove 12 of the insulating body 1 from back to front, its front end protrudes into the insertion space 11 , and its rear end part is exposed to the rear end of the insulating body 1 .
