2.0mm Pitch Double Row 2×8P High Latch Cow Horn Box Header, SMT Surface Mount Type, Plastic With Integrated Latch Overall Height 21mm, Solder Foot Width 7.3mm, 6T Housing, 0.8μm Gold Plating, 48 Hours Salt Spray Resistance

Description

This 2.0mm pitch 2×8P high ear cow horn box header, commonly known as cow horn male connector, is a high-performance SMT surface mount connector specially designed for PCB surface soldering and board-to-cable connection. Unlike simple box headers without locking latches, this high ear cow horn box header adopts an integrated high latch structure molded together with the plastic insulator housing. The high latch can firmly lock the matched IDC female receptacle after mating, effectively preventing accidental disconnection caused by vibration, pulling force and equipment shaking during long-term continuous operation. This anti-drop locking characteristic makes it the preferred connecting component for equipment that requires stable and secure wiring connection in automated production environments.

The connector housing is manufactured from premium 6T high-temperature resistant engineering plastic. 6T material is a specialized high-performance polymer widely used in precision electronic connectors. It has outstanding heat resistance, excellent mechanical toughness, low shrinkage rate and superior dimensional stability. During the high-temperature SMT reflow soldering process, the 6T plastic housing will not deform, bubble or crack, maintaining precise dimensions after soldering. It can withstand continuous temperature fluctuation inside electronic equipment and resist impact force during assembly and plugging operations. The overall height of the plastic housing including the integrated side latch reaches 21mm. The high ear latch design increases the locking stroke and clamping force when mating with the IDC socket, greatly improving the reliability of the locking connection.

This product features double row 2×8P layout, with a total of 16 contact positions. It adopts SMT surface mount structure, the solder foot width of the SMT terminal is 7.3mm. The SMT patch pins are designed for surface mounting on PCB pads. During reflow soldering, the terminal feet are directly welded on the surface of the circuit board without the need to drill through holes on the PCB. This surface mounting method helps designers save PCB space, simplify circuit board layout and realize high-density wiring design. SMT technology is highly compatible with modern automatic SMT placement machines, supporting high-speed automated assembly, greatly improving production efficiency for mass manufacturing. The 2×8P pin arrangement provides 16 signal transmission channels, perfectly meeting low and medium quantity signal transmission requirements of various electronic control modules, without occupying excessive PCB layout area.

All contact terminals of this cow horn box header are plated with 0.8μm gold plating. Gold plating is a mature premium surface treatment technology for electronic contacts. The 0.8-micron gold layer fully covers the contact area of terminals. Gold hardly oxidizes under normal working environment, which can permanently avoid rust and oxidation of copper base terminals. It keeps contact resistance low and stable throughout the whole service cycle, preventing intermittent signal, poor conduction and signal attenuation caused by terminal oxidation. Stable signal transmission is critical for precision electronic systems. 0.8U gold plating greatly reduces the risk of contact failure, extends connector service life and improves the overall reliability of electronic equipment. Compared with tin-plated connectors, gold-plated terminals maintain stable electrical performance even after multiple plugging cycles and long-term environmental exposure.

This high ear cow horn box header has passed strict 48-hour salt spray test. Salt spray test is an accelerated corrosion verification standard widely adopted in the connector industry. The 48H salt spray performance proves the terminals and plastic assembly have excellent anti-corrosion and anti-rust ability. The connector can run reliably in high humidity, coastal atmosphere, slightly corrosive factory workshop environment. For equipment deployed in humid regions or factories with vapor and trace chemical corrosion, this connector can effectively slow down electrochemical corrosion and reduce maintenance and replacement frequency of wiring assemblies. It greatly lowers the risk of equipment downtime caused by connector corrosion.

The integrated high ear latch is one of the core highlights of this cow horn box header. The latch and insulator are molded in one piece, eliminating the risk of latch falling off. When mating with 2.0mm pitch IDC female socket, the high ear latches clip both sides of receptacle tightly. Operators need to press the two latches to release the socket, which avoids unexpected separation caused by accidental tug or machine vibration. This locking design is widely used in industrial control equipment where continuous and uninterrupted signal transmission is mandatory.

Our factory implements strict multi-stage quality inspection for each batch of cow horn box headers. Every finished product will go through visual inspection, dimensional measurement, pin position tolerance check, terminal flatness test, continuity test, plugging durability test and salt spray aging test before delivery. We strictly control production tolerance to guarantee consistency between mass production goods and customer drawings. Customization service is available for customers with special demands. We can adjust solder foot size, change plating specification, modify pin number, adjust structural height and customize packaging solution. Whether for prototype small batch trial order or mass production large order, we can provide stable quality and professional technical support.
