摘要： Disclosed are two embodiments of a coaxial electrical connector designed for use in hazardous locations. Mating connectors are connected coaxially, and coupled together by means of a threaded connection. When the mating connectors are connected, they cannot be disconnected manually. Rather, a tool is necessary to disconnect the connectors. In one embodiment, each connector includes a generally cylindrical coupler member having integral, axial fingers or tines spaced circumferentially. The couplers are rotatably mounted to inserts in which the connecting elements are embedded. A ratchet assembly permits the couplers to be threaded together to make a connection but is overridden in the unconnecting direction, requiring a tool to be placed in the space between adjacent tines to connect the coupler to an associated outer housing which may then be turned to disconnect the connectors. In a second embodiment, coupling members are provided with a ratchet interface surface having interlocking, yieldable teeth so that when the coupling members are secured by hand, a retaining force secures the coupling members together and prevents disconnection by manual force alone, requiring tools to deform the teeth and disconnect the connectors.

摘要翻译：公开了设计用于危险场所的同轴电连接器的两个实施例。配合连接器同轴连接，并通过螺纹连接连接在一起。连接配对连接器时，不能手动断开连接。相反，需要一个工具来断开连接器。在一个实施例中，每个连接器包括大致圆柱形的联接器构件，其具有沿圆周方向间隔开的整体的轴向指状物或尖齿。联接器可旋转地安装到嵌入连接元件的插入件上。棘轮组件允许联接器被拧在一起以形成连接，但是在非连接方向上被覆盖，需要将工具放置在相邻叉齿之间的空间中，以将联接器连接到相关联的外壳体，然后可以将其连接到断开连接器。在第二实施例中，联接构件设置有具有互锁的可屈服的齿的棘轮接口表面，使得当联接构件被手固定时，保持力将联接构件固定在一起，并且通过单独的手动力来防止断开，需要工具变形牙齿和断开连接器。
