1Reliability
If a non-conductive plastic housing is used for unshielded connection elements, then the housing avoids unwanted couplings and short circuits, but transmission behavior deteriorates at high transmission rates due to alien crosstalk
Solution Approach 1:
The housing is made of non-conductive plastic with selective conductive coatings applied only to specific local areas. The inner surface has conductive zones positioned to provide shielding against alien crosstalk from adjacent connection elements, while the outer surface has conductive areas for electromagnetic shielding. This localized application of conductive properties maintains the overall non-conductive nature of the housing, preventing unwanted couplings while providing targeted protection against interference.
Solution Approach 2:
The housing combines non-conductive plastic material with conductive coating layers to create a composite structure. This composite design allows the housing to exhibit both non-conductive properties (preventing short circuits) and conductive properties (providing electromagnetic shielding). The conductive coatings are applied selectively to specific surfaces and areas, creating a multi-functional housing that addresses both crosstalk prevention and electrical isolation requirements.
2Object-affected harmful factors
If conductive coatings are applied to the housing surfaces, then electromagnetic shielding is improved, but unwanted couplings between adjacent housings may occur
Solution Approach 1:
Conductive coatings are applied selectively to specific local areas rather than covering the entire housing surface. The inner surface receives conductive coatings in zones positioned to shield against alien crosstalk from neighboring connection elements. The outer surface has conductive areas configured for electromagnetic shielding. This localized approach provides necessary shielding while minimizing the conductive surface area that could create unwanted couplings between adjacent housings.
Solution Approach 2:
The non-conductive plastic housing material acts as an intermediary layer between the conductive coatings and the external environment. This intermediate non-conductive matrix isolates the conductive coating areas from direct contact with adjacent housings, preventing unwanted couplings while allowing the conductive coatings to provide their shielding function. The non-conductive plastic serves as a physical and electrical barrier that mediates between the conductive shielding layers and external interference sources.
