摘要： A folded electrical box for mounting an electrical wiring device to a support member. Preferably, the electrical box is formed by folding a unitary blank of thin sheet material. In the preferred embodiment, the electrical box includes an integral mounting bracket. The mounting bracket has a pair of bracket portions extending outwardly from one side wall of the electrical box for coupling the electrical box to a support member. Each of the bracket portions has side mounting section extending from the electrical box for engaging one side of the support member extending perpendicular to the dry wall plaster and a face mounting section extending substantially perpendicularly from the side mounting section for engaging the side of the support member with the dry wall plaster secured thereto. The side mounting section of the mounting bracket is reinforced by folding the sheet material to double its thickness, while the face mounting section has a single thickness to avoid bulging the dry wall plaster. In another embodiment, the mounting bracket is replaced by a pair of fasteners or nails which extend through the electrical box to add rigidity and to prevent unfolding of the box.
摘要翻译：一种用于将电气接线装置安装到支撑部件上的折叠电箱。优选地，电箱通过折叠薄片材料的整体坯料而形成。在优选实施例中，电气箱包括整体安装支架。安装支架具有从电箱的一个侧壁向外延伸的一对托架部分，用于将电箱耦合到支撑构件。每个托架部分具有从电气箱延伸的侧安装部分，用于接合垂直于干墙石膏延伸的支撑构件的一侧;以及面安装部分，其从侧安装部分基本上垂直地延伸，用于接合支撑构件的侧面干墙膏固定在其上。安装支架的侧面安装部分通过折叠片材来加强其厚度，而面部安装部分具有单个厚度以避免膨胀干燥的墙面石膏。在另一个实施例中，安装支架被一对延伸穿过电箱的紧固件或钉子代替，以增加刚性并防止盒子展开。

摘要： A plastic ceiling box adapted to support a ceiling fan thereon and adapted to be mounted on a structural member, such as a ceiling joist. The ceiling box comprises a body member having a lower wall and a pair of side walls defining a recess for snugly receiving the ceiling joist therein. Box mounting holes for receiving box mounting fasteners are located at opposite sides and ends of the lower wall for attaching the ceiling box to the joist. Openings for receiving fan supporting fasteners are formed in the body member adjacent the box mounting holes. Brackets at opposite ends of the body member aid in attaching the body member to the joist. This overall arrangement provides sufficient support and strength to resist dynamic loads of a ceiling fan even though the ceiling box is formed of plastic.
摘要翻译：一种适于在其上支撑吊扇并适于安装在诸如天花板托梁的结构构件上的塑料吊顶盒。吊顶箱包括主体构件，其具有下壁和限定用于在其中紧密地接收天花板托梁的凹部的一对侧壁。用于接收箱安装紧固件的箱体安装孔位于下壁的相对侧和端部，用于将吊顶箱附接到托梁。用于接收风扇支撑紧固件的开口形成在与盒安装孔相邻的主体构件中。身体构件相对端的支架有助于将身体构件附接到托梁。这种整体布置提供足够的支撑和强度以抵抗吊扇的动态负载，即使天花板盒由塑料形成。

摘要： An electrical wall or ceiling box adapted to rapidly and securely couple an electrical wiring device thereto. The electrical box includes a pair of wedge-shaped inserts positioned within a pair of openings in the end walls of the electrical box. The inserts have a threaded, curved face portion for gripping a mounting screw and an oppositely facing sloping face portion for interacting with the sloping wall portions of the openings in the electrical box. The inserts also have a shoulder extending outwardly on three sides for engaging a three-sided ledge within the openings for retaining the inserts therein. This structure results in a significantly higher retention force than in prior devices, tending to resist disengagement of the inserts with the box upon insertion of a mounting screw therein.
摘要翻译：适于将电气接线装置快速且牢固地连接到其上的电壁墙或吊顶盒。电气箱包括位于电气箱的端壁内的一对开口内的一对楔形插入件。插入件具有用于夹持安装螺钉的螺纹弯曲面部分和用于与电箱中的开口的倾斜壁部分相互作用的相对面向的倾斜面部分。插入件还具有在三个侧面向外延伸的肩部，用于在开口内接合三边形凸缘以将插入件保持在其中。这种结构导致比现有装置中显着更高的保持力，倾向于在将安装螺钉插入其中时抵抗插入件与盒的分离。

摘要： A connector structure includes a body having a cylindrical recess dimensioned to receive the end of a piece of conduit and a retaining clip to hold the conduit in the recess. The cylindrical recess is provided with an annular recess. The clip comprises a ring with inwardly extending fingers bent out of the plane of the ring, one or more of the fingers having ends thereof bent to form latch tabs. When the conduit is inserted through the clip into the cylindrical recess, the rings are bent against the inner walls of the cylindrical recess so that the tabs enter the annular recess, the intermediate tabe engaging the outer surface of the conduit to hold the assembly together.
摘要翻译：连接器结构包括具有圆柱形凹部的主体，该圆柱形凹部的尺寸适于容纳导管的一端，以及用于将导管保持在凹部中的保持夹。圆柱形凹槽设置有环形凹部。夹子包括一个具有向内延伸的指状物的环，该指状物从环的平面弯曲出来，一个或多个指状物的端部弯曲形成闩锁片。当导管通过夹子插入圆柱形凹槽中时，环相对于圆柱形凹槽的内壁弯曲，使得凸片进入环形凹部，中间凸片与导管的外表面接合以将组件保持在一起。

摘要： A knockout structure is provided for selectively forming openings for either one of two different sizes of conduit. The center of the inner knockout is offset from the center of the outer knockout, creating an eccentric relationship which permits a positive ground to be established between the smaller conduit and the box wall by a standard lock washer when the smaller conduit is mounted therein. A secure mechanical connection is similarly established.

摘要： A connector for engaging non-metallic liquid-tight conduit includes an inner ferrule having a cylindrical portion with an annular rib dimensioned to be inserted into the end of the conduit, and a surrounding sleeve having a conical outer surface and axially extending slots. The sleeve surrounds the conduit and is engaged by a compression nut which radially inwardly decreases the radius of the sleeve, engaging the conduit between the smaller compressed end thereof and the annular rib on the ferrule. The connector also includes a body with threads to engage the nut and the ferrule and body include means for limiting rotational motion of the ferrule.

摘要： A molded, thermoplastic outlet box is provided with openings near the back wall and clamp arrangements inside the openings. Each clamp arrangement includes a swingable clamp arm having teeth at the end thereof which cooperate with teeth formed on an inner wall of the box to engage a cable which has been inserted. An abutment prevents the clamp arm from swinging inwardly until a predetermined force has been exceeded. Flexibility of the arm is enhanced by parallel slots extending away from the opening on opposite sides of the clamp arm.
摘要翻译：模制的热塑性出口箱在开口附近设有靠近后壁和夹具装置的开口。每个夹具装置包括一个可摆动的夹紧臂，在其端部具有齿，该齿与形成在箱的内壁上的齿配合以接合已插入的缆索。支座防止夹臂向内摆动，直到超过预定的力。臂的灵活性通过从夹紧臂的相对侧上的开口延伸的平行槽来增强。
