斜45度俯视近景，方形1:1画幅，深灰渐变暗调纯净背景，主体为赛博朋克风格圆柱形金属接口装置，外壳采用带细微划痕的拉丝银灰色金属材质，顶部端面内嵌黑色PCB电路板，板面排布金色电路走线与多组镀金接触触点，顶部外圈环绕一圈明亮发光的冰蓝色霓虹灯带，金属侧壁透出粉紫色霓虹光晕，侧面带有小型彩色全息光效装饰条，装置下部连接多层嵌套的精密金属锁扣卡扣结构，接口端引出黑色编织纹理线缆，低角度轮廓光勾勒金属边缘，霓虹自发光形成柔和的溢光效果，整体质感精致硬核，无多余背景元素。

Close-up oblique top-down view, 1:1 square frame, dark gray gradient pure background, the main subject is a cyberpunk-style cylindrical metal connector device, the shell is made of brushed silver-gray metal with subtle scratches, the top end face is embedded with a black PCB circuit board, the board is arranged with golden circuit traces and multiple sets of gold-plated contact pins, the top outer ring is surrounded by a bright glowing ice-blue neon light strip, the metal side wall glows with purple-pink neon halo, the side is equipped with small colorful holographic effect decorative strips, the lower part of the device is connected to a multi-layer nested precision metal buckle structure, the interface end leads out a black braided texture cable, low-angle rim light outlines the metal edges, the neon self-illumination forms a soft overflow effect, the overall texture is exquisite and hardcore, no redundant background elements.
