Ambulances serve as a lifeline between hospitals and emergency patients, and any failure in the hardware equipment associated with ambulances can jeopardize lives. Therefore, various onboard medical devices in ambulances have stringent requirements for the technical performance of crucial components, particularly the connectors. Selecting a highly compatible industrial waterproof connector that meets the demands of medical environments is of utmost importance in ambulance medical devices.

Key Considerations for Connectors in Ambulance Medical Devices:

Reliability of the Connector:

Ambulance medical devices are exposed to environments filled with liquids such as water, medications, and disinfectants. Therefore, industrial connectors used in these devices must have stringent requirements for waterproofing and corrosion resistance. They should have an IP65 or higher waterproof rating, and their salt spray testing performance should be ≥48 hours.

Durability of the Connector:

Ambulance devices are subject to vibrations and require connectors with high resistance to withstand the conditions. This can be achieved by using connectors with outer casings that possess sufficient strength and rigidity. Additionally, the separation force of the connector should not be less than 100N to prevent accidental disconnection.

Safety of the Connector:

Connectors used in ambulance medical devices should comply with technical standards such as UL and TUV, ensuring reliable electrical isolation. Generally, the connector’s insulation impedance should be greater than 100MΩ. The materials used should be environmentally friendly and comply with standards like CE and RoHS, ensuring they do not contain harmful substances like lead, mercury, or cadmium that could cause secondary harm to patients.

Endurance for Continuous Use:

Ambulances are often deployed for extended periods without interruption. Therefore, the waterproof connectors used in these devices should meet standards such as IEC 61984 or GBT 34989, with a temperature rise value ≤30K, ensuring stable performance during prolonged usage.

Interpreting Shine Industry DH20 Series Waterproof Connectors’ Compatibility with Ambulance Medical Devices:

The DH20 3-pin power connector developed by Shine Industry Electric is a highly reliable industrial waterproof connector. It is primarily used in ambulance applications to connect the battery and charging terminals of various onboard medical devices, enabling power distribution to different electrical equipment. It perfectly meets the technical requirements of connectors for ambulance medical devices, demonstrating high compatibility. The key features include:

Reliability of DH20 Connector:

The DH20 series waterproof connectors feature Shine Industry’s patented waterproof design, providing excellent waterproof performance. The standard product has an IP65/IP67 waterproof rating, with the highest level reaching IP68. The connector’s housing is made of high-quality zinc alloy and aluminum alloy, with a salt spray testing performance of ≥48 hours. This ensures that the DH20 series waterproof connectors meet the waterproof and corrosion resistance requirements in the medical environment of ambulances, ensuring reliable operation.

Durability of DH20 Connector:

The DH20 series waterproof connectors exhibit superior durability. The connector’s housing design features an independent patented alloy all-metal structure, surface-treated with chrome plating and anodization, providing high resistance against impacts and collisions that may occur in medical rescue environments. The DH series adopts a three-point spiral locking connection design, ensuring secure locking and a separation force not less than 100N, preventing accidental disconnection.

Safety of DH20 Connector:

The DH series industrial waterproof connectors have obtained professional certifications from multiple countries, such as GBT 34989 (CQC), UL, and IEC 61984 (TUV). They provide high electrical isolation safety, with an insulation impedance of 500MΩ, exceeding the standard requirement of 100MΩ. The connector’s materials comply with environmental standards such as CE, RoHS, and REACH. They are free from harmful heavy metals like lead, mercury, and cadmium, meeting the environmental requirements for ambulance medical devices and ensuring they do not pose any secondary harm to patients.

Minimal Temperature Rise, Stable Performance:

Industrial connectors generate heat primarily at the contact points. The DH series waterproof connectors have a contact impedance of only 1.0MΩ, resulting in minimal heat generation. Moreover, the internal structure of the DH series connectors incorporates Shine Industry’s exclusive patented heat dissipation design, providing sufficient heat dissipation area and channels for efficient cooling. These technological advancements contribute to the excellent temperature rise performance of the DH series connectors, with a temperature rise value ≤30K. This ensures stable performance even during prolonged usage in ambulances.

YM Series: A Full Plastic Anti-Corrosion Option for Ambulance Applications:

In addition to the DH series waterproof connectors, the YM series connectors are also suitable for ambulance medical devices. Both series feature connector types that are fully interchangeable and utilize a spiral locking connection, offering high environmental adaptability.

The main difference between the two lies in their materials. The DH series connectors are made of full metal, while the YM series connectors are constructed with high-performance outdoor engineering plastic. Although the YM series connectors may have slightly lower vibration and impact resistance compared to the full metal DH series, they excel in corrosion resistance. Therefore, if the priority is to prioritize vibration and impact resistance, the DH series connectors are recommended. Conversely, if the priority is salt spray corrosion resistance, the corrosion-resistant YM series connectors are a suitable choice.

Conclusion

when selecting connectors for ambulance medical devices, several factors need to be considered, including reliability, durability, safety, and endurance. Shine Industry’s DH20 series waterproof connectors, with their exceptional performance and compatibility with ambulance applications, provide a reliable and efficient solution. Additionally, the YM series connectors offer an alternative for users who prioritize corrosion resistance. By selecting the appropriate connector based on specific requirements, the medical devices in ambulances can operate seamlessly and reliably, contributing to effective emergency care and potentially saving lives.
