【Product Overview】DC-015 Square Snap-in Embedded Panel DC Power Socket

DC-015 is a DC power socket (jack) with excellent anti-rotation performance, featuring a square snap-in embedded panel design.5.5×2.1mm and and 5.5×2.5mm It is fully benchmarked against international leading manufacturers such as TE Connectivity and Amphenol for panel-mount equivalent product design standards, compatible with standard adapter power plugs.

Unlike traditional round snap-in sockets, the DC-015 adopts asquare front structure with four-corner positioning slots.The device enclosure only requires a standard square hole; the socket pushes in and locks securely. Due to the physical constraints of the square structure, the socket has natural anti-rotation on the panel.Anti-RotationCapability: no matter how the user twists the male power connector, the socket remains as solid as a rock. The terminal block at the tail end adoptsStandard solder lug with hole, making it extremely easy for wire harness hooking and manual flying lead soldering.

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

1. Square panel slot design, achieving 100% physical anti-rotation

This overcomes the pain point of traditional round DC jacks, which tend to rotate and spin within the panel hole under frequent plugging/unplugging or external twisting forces. The square slot precisely engages the edges of the square hole, completely eliminating internal wire pull-outs or poor contact caused by spinning.

2. Tool-free snap-fit panel mounting, significantly saving assembly line labor time

No screws or nuts are required for fastening; assembly personnel simply push from the outside of the chassis, and the connector snaps into place automatically. In semi-automated and manual assembly lines, this can greatly improve assembly efficiency and reduce the total cost of ownership (TCO) of the product.

3. High-elasticity copper alloy contacts, ultra-low contact resistance and anti-arcing

The internal core conductive parts and center pin are made of high-conductivity, high-elasticity copper alloy, with finely nickel-plated/silver-plated surfaces, and contact resistance ≤0.03Ω. They feature excellent fatigue resistance, maintaining tight clamping force even after more than 5,000 repeated insertions and withdrawals, effectively preventing arc flashing under high voltage and high current.

4. High-impact-resistant flame-retardant housing, with reliable temperature resistance and insulation performance

The base is injection-molded from high-heat-resistant engineering plastic that meets the UL94V-0 flame-retardant rating, with a high heat deflection temperature. During manual soldering iron wire-connection processes, the housing base does not shift, melt, or deform, maintaining top-level air tightness and insulation resistance at all times.
