The advantage of medical connectors
When designing new medical devices, one of the decisions faced by medical device manufacturers may be to choose a connector or supporting socket. For some ordinary devices, using standard connector products is a feasible choice. For other special application devices, it may be more appropriate to choose custom or hybrid connectors. Customized connector products usually include engineering technology and mold manufacturing costs, and these upfront costs may be one of the factors in choosing customized connector solutions. However, when the cost of connector design and mold is determined, the cost of customized connector products is usually lower than the unit price of ready-made connector products. The selection of ready-made connector products generally has transparent unit price and high price in the market.


Choose Custom and off the shelf connector products to distinguish them from:

1. Customized logo or other marks according to customer requirements;

2. Unique design is required to ensure that only specific cable or connector products can be connected to the instrument;

3. Multiple signal types must be carried in a single connector, such as high voltage, low voltage, high bandwidth, data, thermocouple, etc;

4. Better meet the cost target of medical devices;

5. The unique pin socket pattern or connector shape is used to prevent the connection of incompatible connector products, so as to improve the safety of medical devices.

6. The shape of the selected connector must match the shape of the medical device;

With the rapid development of connector technology, medical connectors used in the medical field have played a great advantage in the interconnection of medical equipment components. In this way, the interconnection of medical devices can be realized conveniently and effectively, and the rapid plug-in can be realized. Of course, in the challenges that medical connectors need to face, the quality of medical connectors is very important, so how should we detect connectors? Let's talk about how to test the performance of medical connectors


The specific test methods of medical connectors are as follows:

1. Connector plugging force test: verify whether the plugging force of the connector can meet the requirements of the enterprise's product design specifications.

Principle: completely insert or pull out the connector at the specified rate, and record the corresponding force value.
2. Connector durability test: evaluate the impact of repeated plugging and unplugging on the connector, and simulate the plugging and unplugging condition of the connector in use.

Principle: continuously plug and unplug the connector at the specified rate until the specified number of times is reached.

3. Test the cold and hot shock performance of the connector: evaluate the impact of the connector on its performance and quality under rapid and large temperature difference.

4. Voltage withstand test of connector; Verify whether the connector can work safely under the rated voltage and withstand overvoltage, so as to evaluate whether the insulation material or insulation gap of the connector is appropriate.

Principle: observe and analyze whether there is breakdown or discharge in the sample information by applying the specified working voltage between the connector contact and the contact and between the contact and the shell and maintaining it for different times specified by the enterprise.

5. Connector contact resistance test: verify the resistance value generated when the current passes through the contact surface.

Principle: by letting the specified current pass through the connector, measure the voltage drop at both ends of the connector to obtain the resistance value.

6. Connector vibration test: verify the impact of system vibration on the performance of electrical connectors and related components. The vibration data types are random vibration and sinusoidal vibration.

7. Mechanical impact test of connector: verify the impact resistance of connector and its components or evaluate whether its structure is firm. Test waveform: half sine wave, square wave.

8. The resistance of connector insulating material passes the test: verify whether the insulation performance of the connector under high temperature, humidity and other environmental stress meets the requirements of circuit design, or whether its resistance value meets the provisions of relevant technical conditions.

Working principle: the resistance generated when voltage is applied to the insulating part of the connector, resulting in leakage current in the insulating part or inside.

9. Connector salt spray test: evaluate the salt spray corrosion resistance of connector, terminal and coating.

10. High temperature test of connector: evaluate the performance of terminal and insulator after the connector is exposed to high temperature environment for the specified time and whether it can develop and change.

11. The temperature and humidity combination of the connector can be tested by the circulating system: evaluate the impact of the connector stored in the high temperature and high humidity environment on the performance of the connector.

12. Corrosion performance test of connector mixed gas; Evaluate the corrosion resistance of connectors exposed to different concentrations of mixed gases and its effect on their performance.


Many market factors are creating new opportunities for medical grade connectors. With the growth of the population aged 65 and over, the medical device manufacturing industry is also growing. The demand for protecting people's health is changing with each passing day, and the demand of the medical market is also growing significantly. Next generation devices are taking advantage of the growing Internet of things to improve connectivity. Devices designed for home use must be able to communicate with expert medical teams for diagnosis. Fixed imaging equipment needs to be able to quickly transmit information between departments or facilities, and the connectors in these equipment must be able to facilitate fast data transmission. In addition, they must be able to withstand various methods of use by patients and medical staff with different experiences, especially under great pressure.


Small portable electronic devices, such as rotary dental tools for cleaning teeth, can easily be discarded in the clinic educational environment. The internal connector enterprise must be able to ensure the safe management of the connection in case of vibration, collision and sudden impact. Larger devices, such as MRI, X-ray equipment, and medical service machines equipped with wheeled trolleys, may be squeezed into door frames and walls, or hit by patient gurney or cleaning staff. Therefore, once again, safe and effective connection is the most important. In addition, disposable equipment is a rapidly growing research field of medical facilities and equipment. We need disposable connectors, which cannot find a balance between high performance and cost control.


Medical connectors are practical and widely used. They are developing into a new connector field, providing better treatment and care performance, and dealing with many information transmission problems. At the same time, it also has a great impact on the acceleration of industrial automation!
