Requirements for circular connectors for power devices
For power supply devices, customers may face the following pain points when using circular connectors

Pain points in power device connections

Electrical reliability of connectors
With the passage of time, the number of insertion and removal increases, the contact resistance of the connector may increase, affecting the current transmission efficiency, and may lead to excessive heating, or even short circuit or equipment damage.
In high current or vibration environments, poor contact can cause frequent power outages or unstable performance.

Resistance to shock and impact
Vibration or impact may cause the internal contact points of the connector to loosen or misposition, and in serious cases, may cause poor contact or power failure.
The structure of the connector housing may not be able to effectively resist the impact of vibration on the sealing performance, resulting in a reduction in the protection level of the connector, which in turn leads to the entry of substances such as water and dust, affecting the electrical performance.

Waterproof and dustproof grade
The protection level of the connector is insufficient, and the entry of moisture and dust will lead to corrosion or short circuit of the contact surface, affecting the stability and safety of the power supply.
In harsh environments such as high humidity and high salt spray, the sealing material and protective coating of the connector may age, resulting in a gradual decline in protective performance.

High current and high power carrying capacity
Unreasonable conductive material or design of the connector may lead to heat accumulation, especially in the case of high current transmission, too high temperature will cause the connector to melt, burn and other failures.
If the rated current of the connector is insufficient, long-term high load operation may lead to increased contact resistance, power instability, and even equipment shutdown.

Mechanical connection strength and insertion life
Frequent insertion and removal will cause the insertion and removal force of the connector to increase, and even cause mechanical damage to the plug or socket, affecting the electrical contact quality.
The design and material selection of connectors may limit their insertion and removal life and may cause contact wear and electrical failure in high frequency insertion and removal environments.

Electromagnetic Compatibility (EMC)
If the circular connector is improperly designed and the shielding effect is poor, it may lead to high-frequency signal interference and affect the electrical performance of the device.
Improper grounding design may cause radiation interference or signal loss, affecting the electromagnetic compatibility of the device.

High temperature and corrosion resistance
Unsuitable material selection can lead to plastic aging at high temperatures, metal corrosion or solder point loss, affecting the mechanical and electrical properties of the connector.
In strong chemical or salt spray environments, metal contact points are susceptible to corrosion, reducing the quality of electrical connections and affecting the long-term stability of the power supply.

Size and compatibility issues
In a limited space, the size and shape of the connector may not be compatible with the design of the power supply device, resulting in difficult installation.
Interface standards are not uniform across devices and may require additional adapters or custom connectors, which adds cost and complexity.

Cost control challenge
High quality, high durability connectors tend to be more expensive, especially when they need to carry high currents, high power or work in harsh environments, which will significantly increase the overall procurement cost.
If the selected connector is not durable enough and requires frequent replacement or maintenance, it will also increase long-term maintenance costs.

Long-term stability and low maintenance requirements
The short service life of the connector will lead to frequent replacement needs, increasing the operational downtime and maintenance costs of the equipment.
Under the conditions of high temperature, high humidity or high load operation for a long time, the performance of the connector will gradually degrade over time, affecting the reliability and safety of the equipment.
