[0002] With the development of intelligence and AI, the intelligence of automobiles has also developed rapidly, and correspondingly, new requirements have been put forward for automotive high-speed wiring harness connectors, which require high-speed wiring harness connectors to support higher bandwidth and better transmission performance. In order to effectively shield external interference from the signal transmission inside the wiring harness connector, existing wiring harness connectors usually have a built-in shielding structure. The main purpose of this shielding structure is to achieve the effect of shielding current. Normally, the shielding structure is directly sleeved on the outer shell of the fixed wiring harness inside the wiring harness connector, so that the shielding structure is in close contact with the outer shell surface of the fixed wiring harness. When the shielding structure is sleeved on the outside of the outer shell of the fixed wiring harness, it may not be completely fitted with the outer shell of the fixed wiring harness, resulting in poor contact and poor shielding effect.
