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.
