Abstract

The invention discloses a fast-assembled modular cabinet for a high-strength vibrating environment. The cabinet comprises a mother board (1). The cabinet further comprises a bus backboard (2), a leftside board (3), a right side board (4), a back side board (5), a cover board (6), PCBs (7), PCB supporting frames (8), a locking strip (8), a locking strip (9) and a puller (10). The base board (11) has a plate-shaped structure. A PCB motherboard (12) is a rectangular printed circuit board. In assembling, firstly, the assembled mother board (1), the assembled bus backboard (2), the left side board(3), the right side board (4) and the back side board (5) are successively assembled through screws for forming a main structure of the cabinet; and after debugging, in integral-machine assembling, four sides of a PCB assembly (21) are connected and fastened with the cabinet. Each PCB in the cabinet structure is mounted by means of the high-strength PCB supporting frame, thereby reducing vibration magnitude amplification from the cabinet to the component on the PCBs so that the integral machine can be adapted with the high-strength vibration environment.

Description

technical field [0001] The invention relates to a modularized case, in particular to a quick-installed modularized case used in a high-strength vibration environment. Background technique [0002] In the field of aerospace, boards and cards of electronic equipment need to meet the normal operation in a high-intensity vibration environment, and must be electromagnetically shielded. They also need to be sealed to meet many requirements such as anti-mold, salt spray, and even water-tight or air-tight. Therefore, chassis are generally used. For installation and bearing, the structural form of the chassis plays a vital role in whether the board can work normally in a high-intensity vibration environment. The structure of the chassis should be able to stably support the loaded electronic boards, and minimize the chassis to board The vibration magnitude of the components on the card is amplified, and the structure of the chassis should not be overweight, and it must meet the restri...
