1. Contact materials:
The internal contact structure of high-voltage connectors usually uses materials with good conductivity, such as copper, aluminum, copper alloys, or silver, to ensure low resistance and high conductivity. Silver is a commonly used contact material due to its excellent conductivity and antioxidant properties.
2. Contact shape:
The shape of the contact structure can be diverse, including pins, blades, springs, spherical contacts, etc. Designers will choose appropriate contact shapes to ensure stable connections, reduce contact resistance, and prevent electrical gaps.
3. Spring contact:
In some high-voltage connectors, spring contact structures can provide pressure and elasticity, ensuring good contact and maintaining reliable connections in the event of vibration or temperature changes.
4. Insulation and sealing:
To prevent electric shock, arc, and electrical leakage, the internal contact structure of high-voltage connectors is usually designed with insulation and sealing. This includes insulation sleeves, insulation materials, and sealing rings to ensure that the external environment does not affect the internal electrical connections.
5. Anti corrosion coating:
Some high-voltage connectors may require anti-corrosion coatings to increase their corrosion resistance, especially when used in harsh environments.
6. Cleaning and maintenance:
Due to the importance of the contact structure inside high-voltage connectors, regular cleaning and maintenance are necessary to ensure the reliability and safety of the connections.
7. Temperature and pressure tolerance:
The internal contact structure of high-voltage connectors must be able to withstand high temperatures and high pressure environments, therefore the design considers factors such as material selection, insulation, and sealing.
8. Safety design:
The internal contact structure of high-voltage connectors should have a safety design to prevent electric shock and accidental touch. This includes ensuring that the internal parts are not exposed when the connector is not connected.
