【Product Overview】DC-049 DC Power Jack with Dual PCB Positioning Pegs

DC-049 is a DIP through-hole DC power jack (female connector)designed for high-stability requirements. For usage scenarios involving frequent plugging/unplugging or external force pulling, DC-049 features dual PCB mechanical positioning pegs (Dual Positioning Pegs)specially designed on the plastic body, which enable precise alignment when inserted into the PCB and withstand the majority of mechanical shear forces.

DC-049 features a regular flush-mount panel slot, supporting structural housing embedded installation, and is widely used in various household appliances, automotive electronics, security surveillance, and smart control terminals.

[Expert-Level B-Side Selling Points and B2B Procurement Decision Factors]

1. Dual PCB positioning posts design, tear resistance improved by 200%

Compared to products with a single positioning post or none, the dual positioning pin structure completely eliminates vibration during wave soldering or manual soldering, effectively preventing PCB pad copper foil from peeling and cracking due to frequent plugging and unplugging.

2. High-elasticity copper alloy contacts, low temperature rise, no power interruption

The interior uses high-conductivity copper alloy spring contacts with low contact resistance, maintaining a strong grip after repeated plugging and unplugging, ensuring stable power transmission and avoiding excessive heat generation.

3. Panel slot structure for more precise assembly positioning

The front opening features a panel clearance snap-in design, compatible with housing assembly, resulting in tighter seams on the device exterior and significantly enhancing the assembly quality of the end product.
