Challenges

In applications such as outdoor lighting, electric garden tools, and marine equipment, connectors are often exposed to demanding conditions where high humidity, salt spray, and continuous vibration occur simultaneously. Traditional threaded connectors can slow down installation and require additional tools for tightening in the field. Conventional snap-fit connectors, meanwhile, may loosen under vibration, potentially leading to poor electrical contact and unplanned equipment downtime. At the same time, high-current transmission up to 40A places greater demands on contact reliability and insulation performance, making it challenging for conventional connector designs to balance temperature rise and dielectric strength.

The Large 3 Pin (40A) Push Lock Connector addresses these challenges with a self-locking Push Lock mechanism that engages upon insertion, enabling fast, tool-free assembly. With IP67 protection and 48-hour salt spray resistance, the connector is designed to provide reliable performance in demanding outdoor and marine environments. Its 40A rated current and 300V rated voltage support dependable high-current power transmission while helping maintain stable electrical performance under demanding operating conditions.

Positioning

The Large 3 Pin (40A) Push Lock is a high-current circular connector featuring a self-locking, push-to-connect design for fast and reliable assembly. It supports a 40A rated current, IP67 protection, and an operating temperature range of -40°C to 105°C, providing dependable electrical and mechanical performance across demanding operating conditions.

Designed for applications including IoT devices, outdoor lighting, electric garden tools, robotics, AGVs, and marine equipment, the connector addresses key challenges in high-current power connections where fast installation, secure locking, and reliable performance are required in harsh outdoor environments.

Features

Self-Locking Push Lock Design for Fast, Tool-Free Assembly

The Push Lock self-locking mechanism automatically secures the connector when the plug is fully inserted into the receptacle, eliminating the need for threaded rotation or additional tools. Compared with traditional threaded connectors, the design can help shorten installation time at each connection point while reducing the risk of poor contact caused by inconsistent tightening torque. For field installation and equipment assembly, this enables more efficient connector integration, reduces reliance on specialized tools and operator training, and helps minimize connection failures associated with installation errors.

40A High-Current Capacity for Reliable Power Delivery

With a 40A rated current and 300V rated voltage, the connector is designed to support continuous power delivery for high-power equipment. Compared with connectors designed for lower-current applications, its high-current design provides improved temperature-rise performance under demanding loads while maintaining sufficient insulation and dielectric strength. This makes it suitable for high-power applications such as electric garden tools, AGVs, and robotics, helping support stable power transmission and reduce the risk of overheating-related downtime caused by insufficient current-carrying capacity.

IP67 Protection and Wide Temperature Range for Outdoor Applications

The connector provides IP67 protection when mated and supports an operating temperature range of -40°C to 105°C, helping maintain reliable connection performance in environments exposed to dust, rain, and temperature extremes. Compared with conventional indoor-grade connectors, the design provides greater environmental adaptability for outdoor applications, helping maintain housing integrity at low temperatures and insulation performance at elevated temperatures. For applications such as outdoor lighting, marine equipment, and outdoor IoT nodes, the connector can help simplify system protection requirements and reduce the need for additional protective enclosures and frequent maintenance.

Applications

IoT, outdoor lighting, electric gardening tools, robotics, AGVs, and marine equipment.
