For an endoscopy application, a customized connector with 4 coaxial and 26 signal contacts, along with a tailored insulator, requires careful consideration of both the mechanical and electrical properties to ensure optimal performance in a medical environment. Here’s a detailed overview of the key features and considerations for such a connector:

Key Features:

• 4 Coaxial Contacts: Designed to handle high-frequency signals, these coaxial contacts are essential for transmitting high-resolution video and other high-frequency data typically used in endoscopy.

• 26 Signal Contacts: These contacts handle various signals required for endoscope operation, including data transmission, power, and control signals. The high number of contacts allows for comprehensive connectivity in a compact form.

• Customized Insulator: The insulator must be designed to accommodate the specific requirements of the connector, ensuring proper separation between contacts to prevent signal interference and maintain signal integrity. It should also provide excellent dielectric properties and mechanical stability.

• Medical-Grade Materials: The connector and insulator should be made from biocompatible and sterilizable materials suitable for medical environments. This often includes materials that can withstand autoclaving or other sterilization methods.

• Compact and Robust Design: Given the small size of endoscopic devices, the connector needs to be compact yet durable, with a design that can withstand the mechanical stresses of insertion and removal, as well as frequent use.

• EMC Shielding: Effective electromagnetic compatibility shielding is crucial to protect the coaxial and signal contacts from external interference, ensuring clear signal transmission and preventing signal degradation.

• Ergonomic Design: The connector should be easy to handle and connect/disconnect, even in the context of delicate medical procedures. This often includes user-friendly features such as locking mechanisms or intuitive mating designs.

• Sealed and Protected: The connector should be sealed to protect against moisture and contaminants, which is especially important in medical applications where cleanliness is paramount.

Considerations:

• Customization Requirements: Work closely with a connector manufacturer to specify the exact dimensions, pin configurations, and materials needed for the insulator and connector body. Customized solutions often require detailed engineering drawings and prototypes to ensure fit and functionality.

• Sterilization Compatibility: Ensure that all materials used in the connector are compatible with the sterilization processes used in medical settings, such as autoclaving or chemical disinfectants.

• Mechanical Integrity: Given the potential for frequent use and handling, the connector should be designed to withstand mechanical stress without compromising performance or safety.

Applications:

These customized connectors are specifically suited for endoscopic systems where high-frequency video signals and multiple control/data signals need to be transmitted through a compact and robust connection. They are used in various medical and surgical procedures, providing essential connectivity for advanced imaging and diagnostic equipment.

In summary, a customized connector with 4 coaxial and 26 signal contacts, along with a tailored insulator, for endoscopy requires careful consideration of medical-grade materials, mechanical design, and EMC shielding to ensure reliable and safe performance in a clinical environment.
