Product Description

Product Description

XC XCD XCE XCF XCG series Introducing our circular electric connectors designed with cutting-edge bayonet-type fast connection technology. These connectors promise swift connections with unparalleled reliability, compact dimensions, and exceptional high-density features. They are engineered to endure harsh environments, making them ideal for aerospace and military applications. The connectors offer versatile end connection methods including crimping, welding, and printed board welding. Utilizing hyperboloid wire spring jack, they support a plethora of plug and socket structures with various coatings to suit diverse needs. Featuring five-key positioning, they facilitate blind insertion while preventing misinsertion. Additionally, they include an array of accessories like straight shielding nuts and cable clamps. These connectors excel in moisture, mold, rain, and dust resistance, adhering to national military standard GJB2889 and enterprise standards Q/321283HH02-2018, perfect for use in aviation, aerospace, and naval sectors.

Mechanical properties
(1)Common type and through-wall sealing adapter:
-Shell:High strength aluminum alloy or stainless steel
-Shell coating:
For shielding, the coating options include Galvanized in military green, electroless nickel plating, and stainless steel passivation.
For unshielded applications, the coating is anodized in a sleek black finish.
- Insulator: crafted from durable thermosetting material
- Sealing body and sealing ring: made from resilient silicone rubber material
- Contact: manufactured from gold-plated copper alloy ensuring excellent conductivity

(2)Glass sintered square plate seal socket
-shell: made of stainless steel for enhanced durability
- Shell coating: finished with nickel plating for added protection
- Insulator: constructed from high-quality vitreous body
- Contact: crafted from gold-plated Corval alloy for superior electrical performance

(1) AND (2)
- Vibration: designed to endure frequencies from 10 to 2000Hz and accelerations up to 196m/S²
- Impact: capable of withstanding an acceleration of 980m/S²
- Constant acceleration: sustained up to 980m/S²
- Mechanical life: robust design allows for 1000 operational cycles

Environmental performance

- Salt spray resistance: offers outstanding durability with electroless nickel plating and galvanizing lasting 96 hours, and stainless steel passivation enduring 1000 hours
- Working height: optimal performance up to 30,000m
- Air tightness:
Through-wall sealing adapter: maintains a pressure difference of 50.7KPa, with a leakage rate ≤46Pacm³/S
Glass sintering airtight type: withstands a pressure difference of 152KPa, ensuring a minimal leakage rate of ≤0.1Pacm³/S

Behaviour of electricity
-Rated voltage and withstand voltage: meticulously designed to meet all specifications

work environment	Hermetically sealed electrical connector		Common type electrical connector
	nominal voltage(V)	withstand voltage(V)	nominal voltage(V)	withstand voltage(V)
normal temperature status	500	1500	500	1500
Damp-heat condition	500	750	500	1125
Low pressure condition(1KPa)	150	300	250	300

-insulation resistance(MΩ): ensures reliable and consistent performance

-Electrical continuity between enclosures:
aluminium alloy housing maintains continuity at ≤2.5mΩ
Steel shell ensures continuity at ≤5mΩ

Avoid misplugging with precision-engineered design
Typically, the plug and socket shells are ingeniously categorized into five distinct keyways (N/W/X/Y/Z). These keyways are meticulously crafted to be assembled by the manufacturer according to the user's specific key number requirements, ensuring seamless compatibility. This design guarantees that plugs and sockets with corresponding assembly keys of the same variety fit perfectly together, while ensuring that plugs and sockets with different assembly keys remain incompatible, thereby preventing any unintended mismatches.
