[Product Overview] DC-020 Thickened Block-Type Screw-Fixed Panel DC Power Socket with Ears

DC-020 is a DC power socket (female jack) with heavy-duty physical strength, featuring a thickened block-type screw-fixed panel design with ears.5.5×2.1mm and and 5.5×2.5mm It is fully aligned with the Heavy-Duty Flange Mount industrial-grade panel connector design standards of international manufacturers such as TE Connectivity and Amphenol, for standard adapter power plugs.

DC-020 adopts athickened block-type rectangular flange base (Block Flange Base)structure, with mounting holes penetrating the thickened plastic blocks on both sides. During installation, the socket is firmly secured to the equipment chassis or panel via screws, providing extremely highWithstands torque, resists pull-out, and provides anti-vibration performanceEven under harsh conditions involving frequent plugging/unplugging or violent tugging, the connector will never break or collapse. The tail wiring terminal 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. Thickened block-type flange base, strong load-bearing capacity and crack resistance

The base adopts a thickened injection-molded block with reinforcing rib structure, effectively dispersing fastening stress. When assembled with a high-torque electric screwdriver, the ears are not prone to cracking, and it fits perfectly with thicker or heavier chassis panels.

2. Standard 5.5mm cavity, wide compatibility

Adopts a standard 5.5mm outer diameter interface design, offering two center pin specifications of 2.1mm / 2.5mm, widely compatible with most standard power adapters on the market, reducing end-user matching costs.

3. Perforated solder lug, providing strong tin adhesion and pull resistance

The tail three-pin terminal block features standard wire-through holes; wires are threaded through in a staggered pattern before soldering, resulting in full solder fill and low contact resistance. Combined with heat-shrink tubing insulation, it effectively withstands the tensile stress of internal wire harnesses within the chassis, eliminating cold solder joints.

4. High-impact, flame-retardant engineering plastic base

Molded from high-heat-resistant engineering plastic that meets 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.
