The invention discloses a circuit board integrated cage based on a USB bus. The circuit board integrated cage is composed of a box body part, a plug-board part and a back board part. The box body partis square cylindrical, and the front and rear parts of the box body part are respectively filled by the plug-board part and the back board part. The left and right inner walls of the box body part are provided with forward and backward guide slots used for inserting board cards. The front end of the board cards is a board card front connector as a signal acquisition input end, and the rear end ofthe board cards is a board card rear connector as a signal output end. The main body of the plug-board part consists of a front panel, and the center of the front panel is provided with an opening sothat the board card front connector extends out of the opening. The main body of the back board part is a back board, and the back board located inside the box body part is provided with a back boardconnector that is plugged-in with the board card rear connector. The back board connectors are integrated in the form of a USB bus and collected into a USB bus interface. The circuit board integratedcage can adapt to a complex electromagnetic environment, dust is not easy to accumulate thereon, the number of connecting cables is reduced, maintenance is easy, and the cage size and the number of board cards that can be placed can be flexibly adjusted.
Description
technical field [0001] The invention belongs to the technical field of missile-borne electronic equipment, and in particular relates to a circuit board integrated cage based on a USB bus. Background technique [0002] With the development of missile weapon systems, the functional types and quantities of electronic equipment on board will increase, and its layout will become more and more complex. Integrated design is an effective design idea. Correspondingly, since most of the missile-borne electronic equipment is in the form of a board, people have developed a circuit board integrated cage. [0003] Most of the existing circuit board integrated cages are open and have poor three-proof performance. Long-term work will cause a lot of dust to accumulate on the circuit board, resulting in a high failure rate of the circuit board and poor electromagnetic compatibility. In addition, the traditional circuit board has many external connectors, and the wiring is cumbersome and den...
