摘要： An electronic isolation shield mounts on a circuit board, around an electronic component to provide a minimum amount of shielding over a set period of time. The shield has a body made from a shielding material that is sized and shaped to fit around and cover the electronic component. The body has a sealing edge that is adapted to contact an upper surface of the circuit board and surround the electronic component. Resilient downwardly projecting tabs are attached to the body and each includes a securing end that extends past the sealing edge. The tab is securable to the circuit board along a securing axis. The sealing edge of the body is forced into sealing engagement with the upper surface of circuit board. The tab is laterally displaced with respect to the securing axis continuously over the set period of time so that the sealing edge is forced into the circuit board sufficiently to provide the minimum amount of shielding to the electronic component over the set period of time. A method of determining the minimum number of tabs that are required includes ascertaining the creep strain for the tab material, determining the mathematical ratio between pressure applied by the tabs at the beginning of the shield's service life to the pressure applied at the end of the service life, determining the minimum amount of pressure that is required to be applied by the tabs throughout the service life, and determining the minimum number of tabs that are required to apply the determined minimum pressure throughout the entire set period of time based on the determined mathematical ratio.
摘要翻译：电子隔离屏蔽件安装在电路板上，围绕电子元件在一段时间内提供最小量的屏蔽。屏蔽件具有由屏蔽材料制成的主体，其尺寸和形状适于围绕并覆盖电子部件。主体具有适于接触电路板的上表面并围绕电子部件的密封边缘。弹性向下突出的突片附接到主体，并且每个突出部分包括延伸穿过密封边缘的固定端。标签可沿着固定轴线固定到电路板上。主体的密封边缘被迫与电路板的上表面密封接合。突片在设定的时间段内相对于固定轴线横向移位，使得密封边缘被强制进入电路板，足以在设定的时间段内向电子部件提供最小量的屏蔽。确定需要的最小拉片数量的方法包括确定拉片材料的蠕变应变，确定由盾构件使用寿命开始时的拉片施加的压力与服务结束时施加的压力之间的数学比率确定在整个使用寿命期间由标签应用的最小压力量，以及基于确定的数学式确定在整个设定的整个时间段内施加所确定的最小压力所需的最小标签数量比。

摘要： A seal construction of a polymer insulator has a core member, an outer cover member including a sheath portion and sheds, which is arranged on an outer surface of the core member, and a securing metal fitting is arranged on each end of the core member. A tip portion of the sheath portion is arranged between the securing metal-fitting and the core member, and a sealant is arranged between an inner surface of the securing metal fitting and an outer surface of the tip portion of the sheath portion. The seal construction mentioned above includes a small rib projecting radially outward from the sheath portion of the outer cover member. The small rib has a side surface connected to an open end portion of the securing metal fitting via the sealant, and the sealant does not protrude from a portion between the side surface of the small rib and the open end portion of the securing metal fitting.

摘要： The aim of the invention is to provide an improved ventilation valve (8), especially for ventilating a mold (5) in the production of umbrella type insulators (1), so that harmful deformation of the molded body can be avoided during removal from the mold (5). This is achieved by providing the ventilation valve with a rod-like or pin-shaped housing (8.2) with an orifice (8.5) on one of its front faces and by providing a valve body (8.3) on the other front face which is detachably mounted in an axial extension of the valve housing (8.2).

摘要： Methods of manufacturing and assembling a composite insulator are provided. At least one metal end fitting is provided having a sleeve portion which defines a bore with a first diameter, d1. An insulator subassembly is then formed. The insulator subassembly includes a rod of electrically insulating plastic material and an insulator sheath covering at least a portion of the outer surface of the rod. An end portion of the sheath has a deformable circumferential ridge formed on the outer surface thereof. This circumferential ridge has a second diameter, d2, which is greater than the first diameter, d1. The insulator subassembly is then inserted into the bore of the metal end fitting with a spacer member interposed between the metal end fitting and at least the circumferential ridge. The spacer member serves to deform the ridge to define a temporary vent for allowing air within the bore to escape. The spacer member is then removed thereby allowing the resilient ridge to return to its original size and shape to form a tight seal between the metal end fitting and the insulator subassembly. The resultant composite insulator has a construction which includes an insulator subassembly including a rod and a sheath covering at least a portion of the outer surface of the rod. The sheath has an end portion and at least one deformable circumferential ridge formed on an outer surface thereof. The composite insulator also includes a metal end fitting having a sleeve portion that surrounds the end portion of the sheath. An end region of the metal end fitting that overlaps the ridge is free from deformation. As a result, it is no longer necessary to crimp the metal end fitting to form a good seal, although the crimping step could be performed if additional tightness is desired.
