Title
(EN) Switch with safe wiring structure
(ZH) 一种具有安全装线结构的开关
Abstract
(EN) The invention provides a switch with a safe wiring structure. The switch comprises a pre-embedded frame installed on a wall body, a base installed together with the pre-embedded frame, and a main panel installed on the front face of the base, wherein an accommodating cavity is formed in the base; a PCB is installed in the accommodating cavity; a boss is arranged above the base; at least two threading holes are formed in the boss; the threading holes are used for realizing electrical connection between a cable and the PCB in the base; the boss is covered with a protective cover; the protectivecover is rotationally connected with the boss; and the protective cover wraps the threading holes. According to the switch with the safe wiring structure in the invention, the movably connected protective cover is arranged on the base to seal and cover the positions of the threading holes, so waterproof and dustproof treatment on the positions of the threading holes in the base does not need to becarried out by additionally and independently carrying objects such as a cap and the like, installation and operation of workers are facilitated, water mist or dust is prevented from entering the base, and a base body is effectively protected.
(ZH) 本发明提供的一种具有安全装线结构的开关,包括安装在墙体上的预埋框、与预埋框安装的基座和安装在基座正面的主面板,所述基座内设有一容置腔,所述容置腔内安装有PCB板,所述基座上方设有一凸台,所述凸台上设有至少两个穿线孔,所述穿线孔用于与线缆与基座内的PCB板电连接,所述凸台外罩有防护罩,所述防护罩与凸台转动连接,所述防护罩将穿线孔包裹在内。本发明提供的一种具有安全装线结构的开关,在基座上设有活动连接的防护罩对穿线孔的位置进行密封盖合,不需另外单独携带盖帽等物件对基座上穿线孔位置进行防水防尘处理,方便工人安装操作,避免水雾或灰尘进入基座内,对基座本体进行一个有效的防护。
