Изобретение относитс к области радиотехники и предназначено дл использовани при сборке печатных плат в пакет в приборах, подвергающихс большим механическим воздействи м .The invention relates to the field of radio engineering and is intended for use in the assembly of printed circuit boards in a package in devices exposed to large mechanical stresses.
Известно устройство дл креплени плат, выполненное в виде набора последовательно соединенных звеньев, состо щих из замков и рамок с отверсти ми. Замки выполнены в виде стержн , один конец которого снабжен цангой, а другой, проход щий через отверстие в рамке, соединен с разрезной втулкой, взаимодействующей с цангой предыдущего стержн .A device for fastening boards, made in the form of a set of series-connected links consisting of locks and frames with openings, is known. The locks are made in the form of a rod, one end of which is provided with a collet, and the other, passing through a hole in the frame, is connected to a split sleeve that interacts with the collet of the previous rod.
Однако это устройство громоздко и ненадежно в работе, так как может быть использовано лищь в приборах, не подверл енных воздействию больщих механических нагрузок .However, this device is cumbersome and unreliable in operation, since it can be used only in devices that are not subjected to heavy mechanical loads.
Прототипом изобретени вл етс устройство дл креплени печатных плат, выполненное в виде последовательно соединенных звеньев с петл ми, несущими печатные платы, каждое из которых представл ет собой кронштейн , снабженный вилкой и двум ушками, одно из которых образует шарнирное соединение с вилкой последующего звена, а другое служит дл шарнирного соединени петель .The prototype of the invention is a device for mounting printed circuit boards, made in the form of serially connected links with loops carrying printed circuit boards, each of which is a bracket equipped with a fork and two ears, one of which forms a hinged connection with a plug of the next link, and the other serves to swivel the hinges.
Однако и это устройство недостаточно надежно в работе из-за наличи зазоров между звень ми, создающих возможность взаимного перемещени элементов устройства при воздействии механических нагрузок.However, this device is not sufficiently reliable in operation due to the presence of gaps between the links, which create the possibility of mutual displacement of the elements of the device when exposed to mechanical loads.
Цель изобретени - повышение надежности креплени и упрощение конструкции - достигаетс тем, что в устройстве дл креплени печатных плат, выполненном в виде последовательно соединенных звеньев, состо щих из кронштейнов с закрепленными на них печатными платами и с выступами, образующими щарнирные соединени , кронштейн каждого звена снабжен петлей, выполненной в видеThe purpose of the invention is to increase the reliability of fastening and simplify the design, because in the device for mounting printed circuit boards made in the form of series-connected links consisting of brackets with printed circuit boards mounted on them and with projections forming jointed joints, the bracket of each link is provided loop, made in the form of
пластины с втулкой за одно целое с кронштейном , на которой закреплена печатна плата и в полости которой закреплена шпллька с возможностью ст гивани кронштейнов между собой.plates with a sleeve in one piece with the bracket, on which the printed circuit board is fixed and in the cavity of which the splice is fixed with the possibility of the brackets being pressed together.
На фиг. 1 схематически изображено предлагаемое устройство дл креплени печатных плат, общий вид; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - кронштейн. Устройство дл креплени печатных платFIG. 1 shows schematically the proposed device for mounting printed circuit boards, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - bracket. PCB Attachment Device
выполнено в виде последовательно соединенных звеньев, состо щих из кронштейнов 1 с закрепленными на них печатными платами 2 и с выступами 3, образующими шарнирные соединени .made in the form of serially connected links consisting of brackets 1 with printed circuit boards 2 fixed on them and with protrusions 3 forming hinged connections.
