Connectors are components in electronic devices that connect power circuits to transmit current, boasting indispensable performance. The majority of a connector's structure can be divided into four main parts: contact pieces, insulators, housing, and accessories.

Contact: Comprising of positive and negative contacts, it is electrically connected by mating the two contacts of the female connector, which are arranged in three rows of pins. The contact piece is a critical component of the connector, primarily responsible for the electrical connection function.

Insulators: Contact pieces can be arranged according to the required location and spacing, ensuring the dielectric strength between the center of the mounting socket contact pieces. Insulators, also known as bases or mounting plates, require insulating materials with excellent grounding resistance, high working voltage resistance, and ease of use.

Customized Piercing Shell: As the housing for connectors, it is crucial for the installation board of the inner window insulation layer and the pin insertion for industrial equipment maintenance.

Attachments: There are two types of accessories - structural and installation. Structural accessories include items such as retainer rings, connecting rings, cable clamps, locating pins, lead pins, seals, and gaskets; installation accessories consist of screws, nuts, extruder screws, spring washers, etc.

After the manufacturing process of pin headers by the pin header producer, it is generally necessary to conduct inspections on the finished products. For example, for connector testing like BTB/FPC, it is required to select a high current spring plate gold micro-needle contact group for connection, which can serve the function of breaking and making current, ensuring the stability of the test. The gold micro-needle contact group with current springs can withstand a load of up to 50A and has a usable pitch as small as 0.15mm. It boasts an average lifespan of 20,000 uses, high precision, and low characteristic impedance, which is beneficial for enhancing testing efficiency.
