Description

Technical Field

[0001] This utility model relates to the field of shielding devices, specifically a shielding structure for an electrical connector. Background Technology

[0002] The background technology of electrical connector shielding structures mainly involves solving electromagnetic interference (EMI) and electromagnetic compatibility (EMC) problems, ensuring reliable and stable signal transmission in various electrical and electronic devices. In modern electronic equipment, circuits generate electromagnetic radiation during operation, especially in high-frequency signal transmission or high-speed digital communication, where EMI is particularly prominent. Unshielded connectors can lead to signal distortion, data loss, or malfunctions. Shielding technology adds a conductive shielding layer or structure (such as a metal shell, shielding cover, or shielding mesh) to the outside of the connector, forming a Faraday cage to prevent external electromagnetic waves from entering or internal signal leakage. The shielding structure needs to have good conductivity, grounding effect, and high shielding performance.

[0003] Chinese Patent No. CN202384579U discloses an electrical connector with a shielding structure, including a housing, an adapter connected to the housing, a thermoplastic sleeve fitted onto the adapter, and a shielding mesh. One end of the shielding mesh is fitted onto the adapter, which has a rear cover that protects the shielding mesh. The thermoplastic sleeve is fixed to the adapter and the rear cover. This design reduces the overall size of the electrical connector, lowers component costs, reduces manufacturing processes, and improves work efficiency.

[0004] Existing electrical connector shielding structures have issues such as an integrated shielding shell design, a wide range of shielding materials, resulting in high costs, an inability to adapt shielding to specific needs, and the possibility of loosening of the pin conductor connection due to vibration or thermal expansion.

[0005] Therefore, a shielding structure for electrical connectors is proposed to address the above problems. Utility Model Content

[0007] The technical solution adopted by this utility model to solve its technical problem is: an electrical connector shielding structure, including an outer flexible insulating shielding layer, a high conductivity copper shielding layer and a pin conductor assembly.
