A push-pull connector is an interface device that enables quick connection and disconnection through "push" and "pull" actions. It features a built-in self-locking mechanism (such as claw locks, spring clips), automatically locking when pushed in and unlocking when pulled out, eliminating the need for rotation and significantly enhancing operational efficiency. Push-pull connectors play a crucial role in scenarios involving high-frequency plugging and unplugging, harsh environments, or limited space.

Push-pull connectors consist of plugs and sockets, with integrated conductive contacts or mechanical interfaces inside. The self-locking mechanism utilizes designs like claw locks and slots, locking automatically upon pushing and unlocking when the release button is pulled. Some models have guide grooves to ensure precise alignment. Metal push-pull connectors typically have casings made of aluminum alloy or high-strength engineering plastics. Combined with sealing designs, they achieve an IP67+ protection rating, offering water, dust, and vibration resistance. Additionally, stainless steel spring components and gold-plated contacts provide a minimum of 5,000 insertion and extraction cycles, and the pearl chrome plating process on the metal casing enhances corrosion resistance.

Push-pull connectors can be operated with one hand, increasing connection speed by 3 - 5 times in high-frequency scenarios. The locking structure passes the USCAR-2 vibration test, ensuring stable connections in highly vibrating environments. They have a wide operating temperature range from -55°C to 200°C, and an IP68 protection rating allows them to withstand high-pressure steam flushing. They also support the mixed transmission of power, signals, and data.

In the industrial and new energy sectors, push-pull connectors are used for fast charging of electric vehicles, energy storage device connections, and tool changing interfaces of industrial robots. The B series push-pull connector, as a general-purpose product, is applied in industrial automation production lines, capable of adapting to harsh environments. In medical equipment, their convenient operation and reliable connections meet various connection requirements such as electrical and pneumatic circuits, for interfaces of endoscopes and monitors. In the communication field, coaxial T-series push-pull connectors ensure stable transmission of 5G and 6G signals. In areas with high protection requirements, the K series push-pull connector (IP67 protection) is used for outdoor lighting, while the W series is suitable for underwater detection (IP68 protection). In aerospace and defense, push-pull connectors meet the demand for stable equipment operation in extreme environments, such as satellite payload interfaces and military communication devices.
