Problems solved by technology

[0002] The existing large-size inductor installation process is: directly solder an inductor pin with a size of Φ30×20mm and a weight of about 35g to the controller printed board and fix it. This inductor installation process is only applicable in the aerospace field. Perform small-scale random vibration tests on the controller; during the large-scale random vibration test (such as 30g and above), the inductance pins will break

Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0024] like figure 1 As shown, it is a large-volume inductor installation structure for aerospace field according to the present invention, including an inductor 2, a printed board 1 and an extension wire 3; wherein, the diameter of the large-volume inductor described in this embodiment does not exceed 35mm.

[0025] On the printed board 1, a hole is opened at the corresponding position of the inductor 2 to make room for binding the inductor 2 with the fastening wire 5. The specific opening is that the printed board 1 has a larger first hole at the center of the inductor 2. A hole. The diameter of the first hole does not exceed the inner diameter of the inductor 2. After the inductor 2 is installed, there are a plurality of smaller second holes on the upper and lower sides. In this embodiment, the inductor 2 is provided with three second holes on the upper and lower s...

Abstract

The invention discloses a large-volume inductor installation structure and process for aerospace field, comprising an inductor and a printed board; the printed board is located below the inductor, the inductor is fixedly connected to the printed board, and the pins of the inductor are arranged facing upward; The inductor is provided with a plurality of pins, each pin is connected with one end of an extension wire, and the other end of the extension wire is connected with the printed board. The inductor can work reliably in a large number of random vibrations without causing fatigue fracture of the inductor pins, which improves the environmental adaptability of the entire product.

Description

technical field [0001] The invention belongs to the field of printed board preparation, and relates to a large-volume inductor mounting structure and process for the aerospace field. Background technique [0002] The existing large-size inductor installation process is as follows: an inductor pin with a size of Φ30×20mm and a weight of about 35g is directly welded to the controller printed board and fixed. This inductor installation process is only applicable in the aerospace field. Conduct a small-scale random vibration test on the controller; during a large-scale random vibration test on the controller (such as 30g and above), the inductor pin will be broken. The reason for the analysis is: when the magnitude of the vibration in the Z direction is 30g, the inductance pins are stretched, and the force on the inductance pins is 9.46N (the weight of the inductance is 35g), and the maximum tensile stress of each pin is 470MPa ( Regardless of the fixing effect of silicone rubb...
