摘要： An electrical outlet box optionally having in combination therewith, a connector fitting for connecting a corrugated conduit to the box, the box having a back wall and at least one side wall of synthetic resin. A pressure removable plug is displaced out of the plane of the side wall so as to provide a precisely delineated zone of weakness surrounding the plug. When one preferred type of connector fitting is used in combination with the box, a wedge-shaped end portion of the fitting, having a relatively small surface area, is manually pressed against the pressure removable plug along a pressure zone immediately radially inwardly from the zone of weakness. This pops the plug out of the wall of the box, leaving a neat, smooth hole into which the connector fitting may be inserted by continued manual pressure applied thereto. The connector fitting includes an expandable cylindrical body portion, and further includes an external circumferential groove at the intersection of the cylindrical body portion with the wedge-shaped end portion. The edge of the wall which defines the opening formed on removal of the plug snaps into this groove to interlock the connector fitting in the wall of the box.
摘要翻译： 可选地与其组合的电源插座，用于将波纹管道连接到箱体的连接器配件，该箱体具有后壁和合成树脂的至少一个侧壁。 压力可拆卸插头从侧壁的平面移出，以便提供围绕塞子的精确描绘的弱点区域。 当一种优选类型的连接器配件与箱体组合使用时，具有相对小的表面积的配件的楔形端部部分沿着压力区域被手动压靠在压力区域上，该压力区域从该区域的径向向内 的弱点。 这将插头从盒子的墙壁上弹出，留下一个整洁，光滑的孔，连接器配件可以通过施加到其上的持续手动压力插入到该孔中。 连接器配件包括可扩展的圆柱形主体部分，并且还包括在圆柱形主体部分与楔形端部部分的交叉处的外部周向槽。 限定在移除插头上形成的开口的壁的边缘卡入该凹槽中以将连接器配件互锁在盒的壁中。
