As a matching component for the male straight head, this female straight head is also manufactured with great rigor. The selection of raw materials complies with the conventional standards in the industry. The insulating materials ensure safety, and the metal contact parts are well-matched with the male head. The molding process relies on precision injection molding combined with basic mechanical processing. The outer shell completely wraps the internal parts. The four pin holes are precisely positioned according to the male head. With the help of conventional calibration methods, it is ensured that the connection with the male head is tight, the contact resistance remains at a relatively low level, and the signal loss is reduced. Its appearance conforms to the general interface specifications. The straight head style is conducive to convenient installation on common circuit boards and equipment frames. Relying on its good compatibility, it is widely used in the connection of electronic circuits for common automation equipment, smart home products and so on, ensuring the normal connection of the circuits.
