摘要： There is disclosed an electrical connector system for a device powered by high current comprising a plug with two high current female contacts and one low current female contact, a socket in the device having two high current male contacts and one low current male contact. The high current contacts are longer than the low current contact so that when the plug is inserted, the high current contacts make connection before the low current contact and when the plug is removed the low current contact is disconnected first, breaking the circuit and preventing arcing. The high current contacts in the socket are electrically connected to the electrical device by a solid-state switch wherein the control gate is operated by the low current contact.
摘要翻译：公开了一种用于由大电流供电的装置的电连接器系统，其包括具有两个高电流母接触件和一个低电流母接头的插头，该装置中的插座具有两个高电流公接头和一个低电流公接头。高电流触点比低电流触点长，因此当插头插入时，高电流触点在低电流触点之前进行连接，并且当插头被移除时，低电流触点首先断开，防止电弧。插座中的高电流触点通过固态开关电连接到电气装置，其中控制栅极由低电流触点操作。

摘要： There is disclosed an electric cord mechanical interlock system which prevents the user from removing or inserting the cord of an electric appliance when the appliance is switched on thus preventing arcing across the contacts. Arcing is prevented by providing an extension as part of the on-off switch control which, when the switch is off, engages and raises a flexible arm containing a pin, allowing the plug to be inserted or removed.
摘要翻译：公开了一种电线机械互锁系统，其防止用户在开启设备时移除或插入电器的电线，从而防止电弧穿过触点。通过提供扩展作为开关开关控制的一部分来防止电弧，当开关断开时，接合和升起包含销的柔性臂，允许插头被插入或移除。
