Conductive Elastomers 导电橡胶 FASTENER REQUIREMENTS 紧固件要求 1. Applied Force 1. 施加的力 Most applications do not require more than 100 psi (0.69 MPa) to achieve an effective EMI seal. 在大多数应用中,仅需不超过 100 psi (0.69 MPa)的力即可达到有效的 EMI 密封。 Waveguide flanges often provide ten times this amount. Hollow strips require less than 10 pounds per in. Compression deflection data for many shapes, sizes and materials is included in the Performance Data section of this Design Guide. 波导凸缘通常可提供 10 倍 的力。空心垫条要求力小于每英寸 10 磅。各种形状、尺寸和材料的压紧变形参数见本设计指南中的“性能参数”一章。 The force required at the point of least pressure, generally midway between fasteners, can be obtained by using a large number of small fasteners spaced closely together. Alternatively, fasteners can be spaced further apart by using stiffer flanges and larger diameter bolts. Sheet metal parts require more fasteners per unit length than castings because they lack stiffness. 受压最小点(通常是紧固件之间的位置)上所需的力,可通过使用大量间距较小的小型紧固件实现。作为选择,通过采用刚性较大的凸缘和大直径螺栓,可以增加紧固件之间的间距。板金件因刚度低于铸造件,因此每单位长度需要更多的紧固件。 To calculate average applied force required, refer to load-deflection curves for specific gasket materials and cross sections (see Performance Data). 如要计算所需施加的平均力,请参见特定垫片材料和截面类型的荷载-变形曲线(见性能参数)。 2. Fastener Sizes and Spacing 2. 紧固件尺寸和间距 Fastener spacing should be determined first. As a general rule, fasteners should not be spaced more than 2.0 inches (50 mm) apart for stiff flanges, and 0.75 inch (19 mm) apart for sheet metal if high levels of shielding are required. An exception to the rule is the spacing between fasteners found in large cabinet doors, which may vary from 3 inches (76.02 mm) between centers to single fasteners (i.e., door latches). The larger spacings are compensated for by stiffer flange sections, very large gaskets, and/or some reduction in electrical performance requirements. 应首先确定紧固件间距。作为一般原则,如果要求较高的屏蔽等级,刚性凸缘上紧固件之间的间距不可大于 2.0英寸 (50mm);而板金上紧固件之间的间距不可超过0.75 英寸(19mm)。作为例外情况,在大型机柜的柜门上,紧固件之间的间距可在3 英寸(76.02)的中心矩到单个紧固件的范围内(即门插销)。更大的间距可通过更具刚性的法兰截面、非常大的垫片和(或)降低某些电气性能要求对其进行补偿。 The force per bolt is determined by dividing the total closure force by the number of bolts. Select a fastener with a stress value safely below the allowable stress of the fastener. 每螺栓上承受的力可通过总闭合力除以螺栓个数确定。在选择紧固件时,应保证该紧固件承受的应力值绝对小于紧固件的许可应力。 3. Flange Deflection 3. 凸缘变形 The flange deflection between fasteners is a complex problem involving the geometry of the flange and the asymmetrical application of forces in two directions. The one-dimensional solution, which treats the flange as a simple beam on an elastic foundation, is much easier to analyze and gives a good first order approximation of the spacings required between fasteners, because most EMI gaskets are sandwiched between compliant flanges 凸缘在紧固件之间的变形是一个非常复杂的问题,其中涉及凸缘的几何形状、及力在两个方向上施加的对称性。将凸缘视为支撑于弹性基础上的简支梁的一维方法可以非常简单地分析紧固件之间所需的间距和确定较好的一次近似值,因为大多数的 EMI 垫片都是夹持于相容的凸缘之间。 |
