    摘要： A system for mounting a recessed electrical or electronic device housing in (behind or above) a wall or ceiling surface utilizes a pair of resilient spring clips that are threadedly attached to respective diametrically opposed threaded screws. The threaded screws are accessible from the front surface of the housing so that the recessed-mounted housing may be inserted into a hole in the wall or ceiling material and fixedly mounted therein by rotating the screws from the front (ceiling or wall) surface of the housing. Each spring clip includes a bearing tab that bears down against the back side of the wall or ceiling material to sandwich the ceiling material between the bearing tab and an annular flange on the front, open end of the housing. Each threaded screw is journaled in a shouldered bushing which is press-fitted into the housing annular flange. The length of the shouldered bushing approximates the thickness of the ceiling or wall material so that, when the spring clip bearing tab bears down against the back side of the ceiling or wall material, the bearing tab is essentially coplanar with the back side of the material in order to distribute the retaining force of the housing and the weight of the housing and its contents over a maximum area of the ceiling or wall material in contact with the spring clip bearing tab. The spring clip is adapted to compress slightly inwardly (toward the housing) as the housing is inserted into a hole in the ceiling or wall material, springing back outwardly in a manner to grip the back side of the ceiling or wall material once the spring clip is beyond the back surface of the ceiling or wall material. Thereafter, tightening the spring clip down against the back side of the ceiling or wall material retains the recessed-mounted housing in place.

    摘要翻译： 用于将凹入的电气或电子装置壳体安装在墙壁或天花板表面（后面或上方）的系统利用一对弹性弹簧夹，螺旋连接到相应的直径相对的螺纹螺钉。 螺纹螺钉可从壳体的前表面接近，使得凹入安装的壳体可以插入到墙壁或天花板材料的孔中并且通过从螺栓的前部（顶板或壁）表面旋转螺钉而被固定地安装在其中 住房。 每个弹簧夹包括承载翼片，该承载翼片抵靠壁或天花板材料的后侧，以将天花板材料夹在轴承翼片和壳体的前部开口端之间的环形凸缘之间。 每个螺纹螺纹都轴颈安装在一个肩部衬套中，该衬套被压配合到壳体环形凸缘中。 肩带衬套的长度近似于天花板或墙壁材料的厚度，使得当弹簧夹承载接片抵靠天花板或墙壁材料的后侧时，承载片基本上与材料的背面共面 以便将壳体的保持力以及壳体及其内容物的重量分布在与弹簧夹支承片接触的天花板或墙壁材料的最大面积上。 弹簧夹适合于当壳体插入天花板或墙壁材料的孔中时稍微向内（朝向壳体）压缩，弹簧夹以弹性回弹的方式夹住天花板或墙壁材料的背面一旦弹簧夹 超出天花板或墙壁材料的背面。 此后，将弹簧夹紧压靠在天花板或墙壁材料的背面，将凹入安装的壳体保持在适当位置。
