The square dust-proof cover includes: a body, which is a square cover, forming a narrower side on the left and right sides and a wider side on the upper and lower sides. The wider outer end has a radian, and a rounded corner at the connection with the narrower outer end. The front end of the body forms a square opening, the rear end has a protective wall, and the inner front end of the body forms an outer wide inner narrow side to the inner back end of the body. The outer end of the protective wall and the body are provided with rounded corners; the plural clamping rib is a long strip, convex from the inner part of the narrower side and the inner part of the wider side of the body, and the clamping rib forms an outer wide inner narrow taper from the inner front end of the body to the inner back end of the body, and the front end is connected with the body with a rounded angle; the plural friction part is a rectangular cylinder, which is located in the body. Its dust-proof effect is better than that of conventional technology. It is not easy to loosen and plug out. It has strong practicability, high safety, excellent insulation and corrosion resistance.

方型防尘盖
本创作系关于一种防尘盖;更详细而言,本创作系关于一种方型防尘盖。
技术介绍
现有技术之防尘盖,一般适用于光纤导线的插头上,而光纤导线为一种讯号传转线,其主要具有下列的特性及优点:1.光纤导线主要在传输先的讯号,是属于宽带传输的讯号线,所能传输的讯号范围较广。2.光纤导线所传输的是光波,而非电波,故不会产生感应电磁波,便传讯中不会干扰其它无线通信设备,也不会被外来电磁波所干扰,故而传讯质量既稳定且优良。3.光纤导线传递讯号的速度较快,已为通信业公认最佳的传输线。上述之光纤导线的价格昂贵,在一般家庭里大都作为音响的声音传输线,或者作为PDA、DVD的信号传输线,以使声音、画质的显现效果良好。然而,该光纤导线若沾染到灰尘,即会严重的影响传讯质量,是以该光纤导线的插接头的前端必须用防尘盖包覆以防尘。但是,目前市面上之防尘盖仅为一简易的外套盖包覆于光纤导线之外,容易导致松脱而无法达成防尘的效果。有鉴于此,如何提供一种方型防尘盖,可有效解决上述问题点,乃为目前业界引领期盼所欲解决之问题。新型内容本创作之目的在于提供一种方型防尘盖,其可有效保护光纤之插接头内不会进尘 ...
