Robust FC Series Mini-Rectangular Connectors from China Suppliers - Reliable Power Connection Factory Solutions
Features and Advantages
-
1The connector system incorporates two key functional features. First, it includes a polarization or keying device to ensure correct mating orientation, preventing accidental reverse insertion that could damage sensitive circuitry — a critical advantage for protecting electronic modules.
-
2Second, it is equipped with a locking screws device (such as a captive screw or thumbscrew system).
-
3This mechanism provides a secure, mechanically fastened connection that is highly resistant to vibration and accidental disconnection, offering the significant advantage of enhanced reliability in mobile or high-shock environments.
-
4The combination of these features ensures a foolproof and robust power link. The standardized 2.5mm pitch balances good electrical isolation with a compact footprint, suitable for a wide range of power ratings.
Application
These connectors are primarily used for internal power distribution within
electronic chassis and enclosures. Their typical applications focus on creating reliable,
user-serviceable connections for modular components, including:
⚡
Power Supply Units (PSUs)
Connecting internal AC/DC or DC/DC power modules to the main system backplane or
motherboard in computers, servers, and industrial controllers.
🔧
Internal System Modules
Providing power to fan trays, drive bays, amplifier modules, or sensor arrays within a
larger electronic system.
🔬
Test and Measurement Equipment
Facilitating safe and secure power connections to internal instrument modules.
🏭
Industrial Electronics
Used in PLCs, motor drives, and other control systems where modular design simplifies
maintenance.
Frequently Asked Questions
Q
What is the purpose of the polarization or keying device in this connector system?
The polarization or keying device ensures the connector can only be mated in the correct
orientation. This prevents accidental reverse insertion, which could otherwise damage
sensitive electronic circuitry and cause costly system failures.
Q
How does the locking screw mechanism improve connector reliability?
The locking screw (captive screw or thumbscrew) creates a mechanically fastened connection
that resists vibration and accidental disconnection. This is especially valuable in mobile,
industrial, or high-shock environments where an unsecured connector could cause system
downtime or safety hazards.
Q
Why is a 2.5mm pitch used in this connector design?
The standardized 2.5mm pitch strikes an optimal balance between electrical isolation and
compact footprint. It allows the connector to handle a wide range of power ratings while
keeping the overall size suitable for dense electronic enclosures and chassis.
Q
What types of equipment commonly use these connectors?
These connectors are widely used in computers, servers, industrial controllers, test and
measurement instruments, PLCs, motor drives, and any modular electronic system requiring
reliable internal power distribution. They are ideal wherever user-serviceable, secure
connections are needed.
Q
Are these connectors suitable for high-vibration or mobile environments?
Yes. The combination of the keying device and locking screw mechanism makes these connectors
highly resistant to vibration and accidental disconnection, making them an excellent choice
for mobile equipment, vehicles, industrial machinery, and other high-shock applications.
Q
Can these connectors be used for both AC/DC and DC/DC power modules?
Yes. These connectors are designed to connect internal AC/DC or DC/DC power supply modules
to system backplanes or motherboards. Their robust locking and keying features ensure safe,
reliable power delivery regardless of the power conversion type used within the system.
