What issues should be paid attention to when choosing a Type C to 2RCA connector

Type C to 2RCA connectors are an indispensable part of electronic equipment. If you follow the path of current flow, you will always find one or more connectors.

Type C to 2RCA is a coupling device that connects electrical terminals to form a circuit. It can realize the connection between wires, cables, printed circuit boards and electronic components, so it is widely used in electronic equipment.

With different application objects, application environments, frequencies, and powers, the form and structure of Type C to 2RCA connectors are also ever-changing. There are more and more types of common connectors, so what should we pay attention to when we choose connectors?

1. Electrical parameters

Most Type C to 2RCA connectors are connected to electrical components to transmit current or signals, so there are strict requirements on electrical parameters, mainly including rated voltage and rated current.

The rated voltage, also known as the working voltage, mainly depends on the distance between the insulating material used in the connector and the contact pair. Theoretically, the rated voltage of the connector should be the highest working voltage recommended by the manufacturer, but in fact the connector can work normally at a voltage lower than the rated voltage.

The rated current is also called the working current. Like rated voltage, connectors generally work well below rated current. When current passes through the contact pair of the connector, due to the existence of conductor resistance and contact resistance, the contact pair will heat up, and failure will occur when the temperature exceeds the limit. Therefore, to limit the rated current, it is necessary to limit the temperature rise inside the connector from exceeding the specified value of the design.

2. Environmental parameters

Environmental parameters mainly include ambient temperature, humidity, sudden temperature changes, and corrosive environments. The environment of the connector during use, transportation and storage has a significant impact on its performance, so the corresponding connector must be selected according to the actual environmental conditions.

3. Ambient temperature

The metal material and insulating material of the Type C to 2RCA connector determine the working environment temperature of the connector. High temperature will destroy the insulating material, causing the insulation resistance and voltage resistance to decrease; for metals, high temperature can cause the contact pair to lose elasticity, accelerate oxidation and cause coating deterioration.

4. Humidity

Long-term high-humidity environment will cause water vapor to absorb and diffuse on the surface of the insulator, which will easily reduce the insulation resistance to the point where it will cause physical deformation, resulting in electrolysis, corrosion and cracks. Connectors outside the equipment often have to consider the environmental conditions of humidity, water seepage and pollution. In this case, sealed connectors should be selected. For watertight and dust-tight connectors, the shell protection level of GB4208 is generally used to indicate.

5. Corrosive environment

According to different corrosive environments, Type C to 2RCA connectors with corresponding metal, plastic, and plating structures should be selected. Such as connectors used in salt spray environment, if there is no anti-corrosion metal surface, the performance will deteriorate rapidly. However, in an environment containing a considerable concentration of SO2, it is not suitable to use a connector with a silver-plated contact pair.

6. Connection method

The termination method refers to the connection method between the contact pair of the Type C to 2RCA connector and the wire or cable. At present, the main connection methods include welding, crimping, winding, piercing connection, screw connection and so on. Reasonable selection of termination method and correct use of termination technology are also an important aspect of using and selecting connectors.

Electrical parameters, environmental parameters and connection methods all affect the performance of the connector. Understanding your application requirements and choosing the right connector can improve the reliability of project engineering and have a great effect on improving product quality and service life.
