The invention discloses a spacecraft device and an installation method of a bend-inserted printed board connector. The spacecraft device comprises a bend-inserted printed board connector, a circuit board and a structural housing. The bend-inserted printed board connector is positioned on the structural housing, the rear end of the bend-inserted printed board connector is connected with a connectorflange, and the bend-inserted printed board connector is provided with a curved needle; the circuit board is positioned and fixed on the structural housing, the circuit board is provided with a connector printed board opening for connecting with the bend-inserted printed board connector, and the curved needle is inserted into the connector printed board opening; the curved needle of the bend-inserted printed board connector is welded with a pad on the printed board opening to form an integrated structure of the bend-inserted printed board connector, the circuit board and the structural housing, realizing cabling-free connection between the bend-inserted printed board connector and the circuit board, improving the utilization rate of the internal space of the spacecraft device, avoiding generation of stress, preventing over-positioning and ensuring product quality. The difficulty of installation, later testing and maintenance is reduced, the performance is more stable, resource consumption is reduced, and the overall performance is improved.
