[0002] Under the background of rapid development of electronic technology today, as an indispensable part of electronic equipment, the performance requirement of connector is increasingly improved. Especially in the aspects of insulation and waterproof, the traditional connector design has been difficult to meet the needs of high-end application scenarios. At present, the general connector adopts high polymer plastic as an insulator positioning piece to fix the terminal, and after crimping the cable conductor, the positioning piece and the cable are integrally formed into an insulating shell through an injection molding process. However, for the full shielding connector, the improvement of waterproof performance has become a problem to be solved.

[0003] The full shielding connector increases a metal shielding layer on the basis of the traditional connector to enhance electromagnetic compatibility and prevent external electromagnetic interference. However, the addition of the metal shielding layer brings a series of new challenges, especially in waterproof performance. Because there are gaps between the metal shielding layer and the fixing piece, these gaps are easy to become channels for water vapor penetration when the connector is exposed to a humid environment or immersed for a long time. This not only causes the terminals inside the connector to be eroded by water vapor, affecting their conductivity, but also may cause the connector to completely fail, unable to meet the requirements of high-level waterproof standards such as IPX7.
