50A 80A stackable connector, IP67 waterproof connector, 2+1+5 battery pack

To understand the advantages and features of the 2+1+5 stackable connector, we need to analyze it from various perspectives, including structural design, electrical performance, installation and maintenance, and application scenarios:

>I. Features (Structure and Design)

● Modular Stackable Structure

Adopting a layered layout of "2 (power terminals) + 1 (signal/communication terminal) + 5 (power terminals)," this connector achieves multifunctional integration through standardized interfaces and stackable installation:

● 2/5 are power transmission terminals: meeting high-current, high-power power transmission requirements (such as powering motors and drive devices);

1 is the signal/communication terminal: used for low-current, high-speed signal exchange, including data transmission, control signals, and sensor signals.

● Compactness and Space Optimization

The stackable design significantly reduces the overall connector size, making it suitable for space-constrained industrial equipment (such as robotic joints and automated production line modules), enabling integrated "power + signal" connectivity within confined spaces.

● Interface Identification and Installation Compatibility
Numbered markings (such as "1, 2, 5, 6, and 8" in the image) are included on the housing to quickly identify port functions. Mounting holes are located along the edge of the housing, allowing for a variety of fastening methods (screws, clips, etc.) to accommodate different device mounting structures.

●Industrial-Grade Protective Design
Judging from the material (the dark gray housing in the image) and structure, it offers protection against dust, water, and impact, ensuring reliable connections in outdoor, heavy-load, and harsh environments (IP67-rated protection).

> II. Advantages (Performance and Application Value)

●Multi-Scenario Integration, Cost Reduction and Efficiency Improvement
No longer requiring separate power and signal connectors, the integrated "power + signal" stack reduces equipment procurement, storage, and maintenance costs. It also simplifies wiring logic and reduces harness complexity.

● High reliability and durability
The stacking structure ensures stable plug-in and pull-out force, low contact resistance, and strong long-term stability through precise tolerance control and plug-in self-locking design; combined with industrial-grade protection (dustproof/waterproof/impact-proof), it can operate reliably in harsh scenarios such as industrial robots and new energy equipment for a long time.

● Signal and power separation to ensure safety
The power end (2+5) and the signal end (1) are physically isolated to avoid electromagnetic interference (EMI) of large current on the signal, while achieving the coexistence connection of "strong power (power) + weak power (signal)" to meet the synchronization requirements of "power drive + status monitoring/control".

● Fast deployment and maintenance
The stacking structure simplifies the connection process: the "power + signal" full link connection can be completed in one operation, reducing installation time; in the event of a fault, the modular port can be quickly located and replaced, reducing maintenance costs.

● Compatibility and scalability
The standardized stacking interface is compatible with power modules of different power levels (such as high current, high voltage modules) and signal modules of different speeds, adapting to equipment upgrades and function expansion requirements, and extending the product life cycle.

●The core value of this type of connector is "all-in-one, small size, and high reliability", which perfectly matches the needs of industrial automation, new energy, robotics, etc. for "power + signal" dual transmission, compact space, and harsh environment.
