7/8 connector-assembly crimping plastic shell connector, with a lightweight and durable plastic shell, adapted to 7/8-16UN standard interface, supports 3-5 pins flexible configuration. The product combines assembly convenience and crimping stability, has good insulation performance and environmental adaptability, is suitable for signal transmission and power connection in industrial equipment, control systems and other scenarios, and provides an efficient solution for cable integration.
1. Product Features
The connector uses plastic shell as the core material, which is both lightweight and insulated, effectively reducing weight and improving durability; it adopts the industry standard 7/8-16UN interface design, has strong compatibility, and is suitable for mainstream equipment cables; it supports flexible selection of 3/4/5 pins to meet the signal transmission needs of different scenarios. The assembled structure is matched with the crimping process, which is convenient to install and has close contact, ensuring stable signal transmission and long-term reliability. At the same time, it has certain dust and moisture resistance and is suitable for complex industrial environments.
2. Product size and number of pins
Product size:
Male head: shell diameter 28.0mm, total length 70.2mm, the interface is adapted to 7/8-16UN specifications, and the plastic shell is marked “PC9”;
Female head: shell diameter 30.0mm, total length 60.9mm, also uses “PG9” plastic shell to meet the requirements of different cable outer diameters.
Number of pins configuration: Three specifications are available: 3-pin, 4-pin, and 5-pin (see table). The male and female pinholes are arranged scientifically, and the contacts are evenly distributed to ensure signal integrity when connecting multiple pins, and adapt to the electrical connection requirements of various scenarios.
