摘要： An apparatus for clamping electrical cables, particularly where cables of widely varying diameter are clamped. Cables of relatively greater diameter are accommodated by utilizing clamping jaws with criss-cross gripping ribs to reduce elliptical distortion through a multi-mode distribution of the clamping forces. Cables of relatively lesser diameter are accommodated by extending the gripping ribs to overlap the interface between the clamping jaws and enfold the cable within a conduit. The overlapping and crisscrossed ribs also provide for a more even distribution of the clamping forces to prevent cable ruptures.
摘要翻译：用于夹紧电缆的装置，特别是在夹紧不同直径的电缆的情况下。具有相对较大直径的电缆通过利用具有十字形夹紧肋的夹钳夹住以通过夹紧力的多模式分布来减少椭圆形变形。相对较小直径的电缆通过延伸夹持肋而与夹钳之间的界面重叠并且将电缆覆盖在导管内而被容纳。重叠和十字交叉的肋还提供了更均匀的夹紧力分布，以防止电缆破裂。

摘要： An electrical connector is provided with a thin centrally apertured resilient dust seal gasket that is adapted to hug a conductor cable passing through it. The gasket is held within a cylindrical insulating shell against a radial wall thereof by a flexible wafer made of nylon or equivalent, which in turn is secured to the shell by pins molded with the shell and on which the dust gasket and then the wafer are impaled. The assembly of the gasket and wafer within the shell is done in one pushing operation.
摘要翻译：电连接器设置有薄的中心有孔的弹性防尘密封垫圈，其适于拥抱穿过其的导体电缆。垫圈通过由尼龙或等效物制成的柔性晶片保持在圆柱形绝缘壳体的径向壁之下，该柔性晶片又通过与外壳成型的销固定到壳体上，并且其上的灰尘垫圈然后被撞击。外壳中垫圈和晶片的组装在一个推动操作中完成。

摘要： A connector cap assembly for use in an attachment plug or cable connector wherein the cap assembly comprises a cylindrical body having an open bottom and a top with a cylindrical wall extending upwardly therefrom. A pair of supporting ears projects upwardly from the top to adjustably carry a pair of clamping members by means of a pair of screw assemblies. Cooperating guide means are provided on the clamping members and the wall portions to assure alignment of the clamping members throughout their entire travel.
摘要翻译：一种用于附接插头或电缆连接器的连接器盖组件，其中，盖组件包括具有开口底部的圆柱形主体和具有从其向上延伸的圆柱形壁的顶部。一对支撑耳从顶部向上突出，通过一对螺丝组件可调节地携带一对夹紧构件。配合导向装置设置在夹紧构件和壁部分上，以确保夹紧构件在其整个行程中的对准。
