    • A blocking outlet and corresponding locking plug provide a completely enclosed safety electrical connection system for supplying electrical power from a wall fixture. The blocking outlet installs in a conventional wall-mounted electrical box, providing access to building electrical wiring. The outlet has receptacles that retain spring-loaded covers, which have a closed position generally flush with the front side of the face plate. The springs provide sufficient tension to the covers to block small children from inserting fingers or foreign objects into a receptacle, preventing inadvertent exposure to hazardous voltage. Yet adults can easily insert a corresponding locking plug directly into a receptacle without cover removal. Regardless, the interior of a receptacle has no exposed contacts. Small access apertures in the interior of an outlet receptacle contain recessed contacts. When inserted, the plug compresses the cover fully into the receptacle to an open position, exposing the access apertures to retractable plug prongs. An ergonomic finger hold on the plug is pulled-out to retract the prongs for insertion into an outlet. After insertion, the finger hold is pushed-in to extend the prongs into the access slots, wiping against the outlet contacts and connecting the plug to electrical power. The extended prongs also lock the plug into the receptacle. For removal, the finger hold is pulled-out, unlocking the plug, which can then be easily pulled from the outlet. A face plate seals the receptacles and provides a wall trim for both the electrical box and the outlet in a manner comparable to a standard face plate. An adapter plug has a socket that accepts a standard AC plug, converting it to a locking plug.
    • 阻塞出口和相应的锁定插头提供用于从墙壁固定装置提供电力的完全封闭的安全电气连接系统。 阻塞出口安装在传统的壁挂式电气箱中,提供进入建筑物电气接线。 出口具有保持弹簧加载的盖的插座,其具有通常与面板的前侧齐平的关闭位置。 弹簧为盖子提供足够的张力以阻止小孩子将手指或异物插入插座,防止意外暴露于危险电压。 然而,成年人可以容易地将相应的锁定插头直接插入到插座中而不需要盖子移除。 无论如何,插座的内部没有暴露的触点。 在出口插座内部的小进孔包含凹入的接触。 当插入时,插头将盖子完全压入插座到打开位置,将进入孔暴露于可伸缩的插头插脚。 将插头上的符合人体工程学的手指拉出,以缩回插脚插入插座。 插入后,手指保持被推入以将插脚延伸到接入槽中,擦拭出口触点并将插头连接到电力。 扩展插脚也将插头锁定到插座中。 为了取出,手指保持被拉出,解锁插头,然后可以容易地从插座拉出。 面板密封插座,并以与标准面板相当的方式为电箱和插座提供壁饰。 适配器插头具有接受标准AC插头的插座,将其转换为锁定插头。
