Contacts

‌Contacts‌ in electronic components are the core components of connectors, which are mainly responsible for realizing the conduction function of electrical connection and are indispensable basic components in modern electronic devices.

1. What is the ‌Basic Structure of Contacts?‌

1) ‌Material Composition‌: Contacts are usually made of highly conductive metal materials, such as copper alloys, gold/silver plating, etc., to ensure low resistance and high reliability.

2) ‌Morphological Design‌: According to different application scenarios, contacts can be divided into:

‌Terminal‌: Fixed end for wire crimping or welding.

‌Pin‌: Active end that cooperates with the socket to form a pluggable connection.

2. What are the ‌Functional Characteristics of Contacts?‌

‌Signal Transmission‌: Conducting circuits through physical contact to transmit electrical signals or electrical energy.

‌Current Carrying‌: Need to meet specific current capacity requirements, commonly seen in power interfaces or high-power device connections.

3. What are the ‌Technical Key Points of Contacts?‌

‌Plating Process‌: Surface plating (such as gold plating, and nickel plating) can improve corrosion resistance and contact stability.

‌Elastic Design‌: Some contacts adopt a reed structure to ensure contact pressure and durability during plugging and unplugging.

4. What are the Types of Contacts?‌

5. What is the Failure Mode of Contacts?

Oxidation/Contamination: Oxidation of the contact surface or adhesion of foreign matter leads to increased resistance.

Mechanical Fatigue: Frequent plugging and unplugging causes deformation or breakage of elastic elements.

6. What are Contacts Used for?

Widely used in consumer electronics (such as mobile phones and computers), automotive electronics, industrial control equipment and communication base stations.
