Gold-Plated 3.5mm TRS Audio Connector Plug

Type

Electronic Component Connector (TRS Jack)

Purity

Gold-Plated (typically 24K flash plating over brass)

Gold Type

Yellow Gold (Industrial Flash Plating)

Weight

2.0 - 5.0 grams (Total component weight)

Description

This is a standard 3.5mm Tip-Ring-Sleeve (TRS) audio connector, commonly used for headphones and auxiliary cables. It features a decorative and functional gold flash plating over a base metal (likely brass). The plating serves a dual purpose: providing a premium aesthetic and enhancing corrosion resistance for better electrical connectivity.

Key Features

Triple-contact TRS design (Tip, Ring, Sleeve) with two insulating black spacers; tapered tip for easy insertion; industrial yellow gold plating.

Color & Finish

Vivid rich yellow; industrial polished finish with visible surface patina and micro-scratches from insertion wear.

Hallmarks & Stamps

None visible; industrial components of this type rarely carry precious metal hallmarks.

Dimensions Estimate

3.5mm diameter; approximately 15mm-20mm in length for the plug section.

Gemstones & Inlays

None; features two black plastic/polymer insulating rings to separate Tip, Ring, and Sleeve signals.

Clasp & Closure

None (Friction-fit insertion mechanism for female audio ports).

Chain & Links

Not applicable; solid brass core construction cylindrical rings.

Craftsmanship Details

Precision lathe-turned brass or copper alloy with automated electroplating; consistent tolerances for standard audio jack compatibility.

Authentication Indicators

The 'gold' color is characteristic of industrial electroplating rather than solid gold alloy; consistent weight-to-volume ratio for brass; lack of hallmarks for 24K items.

Origin & Maker

Generic Industrial Manufacturer (likely East Asian mass-production).

Era & Period

Contemporary (Standardized audio technology circa 1950s-present; this specific unit appears modern).

Age Estimate

Likely manufactured within the last 5-10 years based on oxidation patterns.

Cultural Significance

Iconic symbol of the analog audio era and consumer electronics; ubiquitous in music culture until the rise of wireless Bluetooth technology.

Condition Notes

Good; shows visible wear on the contact rings (scuffs) indicating frequent use in an audio jack. Some oxidation/tarnish visible on the upper sections.

Value Estimate

Melt Value: Negligible (less than $0.01 USD in gold content); Market Value: $0.50 - $2.00 as a functional electronic component.

Care & Maintenance

Clean with high-percentage isopropyl alcohol to remove oils; avoid abrasive polish which will strip the thin gold plating; store in a dry environment.

Interesting Facts

Gold is used in electronics because it is a highly conductive metal that does not oxidize or tarnish as easily as copper or silver, ensuring a clean audio signal over time.
