Abstract: Предлагаемое изобретение относится к механизму петли для портативного блока связи с откидной крышкой. Техническим результатом является обеспечение соединения блока связи с полуактивной защелкивающейся частью, при котором соединение разъемного звуковода не пропускало бы посторонние шумы. Механизм петли обеспечивает плотное звукопроводящее соединение в звуководе, который распределен между блоком связи и откидной защелкивающейся частью. По меньшей мере два стержневых элемента соединяют с возможностью вращения, защелкивающуюся часть - с блоком связи. Каждый стержневой элемент размещается в соответствующей точке вращения защелкивающейся части вдоль оси вращения защелкивающейся части. Звуководное соединение размещается в первой точке вращения защелкивающейся части между противодействующей поверхностью на защелкивающейся части и противодействующей поверхностью на блоке связи. Части звуковода, таким образом, соединяются друг с другом вне зависимости от того, какое положение поворота занимает защелкивающаяся часть относительно блока связи. Механизм петли содержит по меньшей мере один сжимающий упругий элемент, который посредством стержневого элемента во второй точке вращения производит усилие на две противодействующие поверхности, так что звуководное соединение сдавливается и становится звуконепроницаемым. 23 з.п. ф-лы, 8 ил.
