Embodiment Construction

[0010] The present invention will be described in further detail below by means of specific embodiments:

[0011] The reference signs in the accompanying drawings of the specification include: a fixing plate 1 , a connecting hole 2 , a fastener 3 , a pressing plate 4 , a nut 5 , a bolt 6 , and an elastic layer 7 .

[0012] The embodiment is basically as attached figure 1 Shown: the fastening device for the circuit board, including a fixing mechanism and two fastening mechanisms, the fixing mechanism includes a fixed plate 1, and the fixed plate 1 is composed of several retractable sleeves, so that it can be adjusted according to the size of the circuit board. The length of the fixing plate 1 is set, thereby expanding the applicability of the device. The two ends of the fixed plate 1 are respectively provided with connection holes 2, and the bolts 6 for connecting the circuit board are movably connected to the connection holes 2. The two fastening mechanisms are relatively arr...

Abstract

The invention discloses a fastening device for a circuit board. The fastening device comprises a fixing mechanism and two fastening mechanisms. The fixing mechanism comprises a fixing plate. The two ends of the fixing plate are provided with connecting holes respectively. The connecting holes are movably connected with connecting pieces. The two fastening mechanisms are oppositely arranged on the fixing plate. Each fastening mechanism comprises a fastening piece fixedly arranged on the fixing plate and a pressing plate movably connected to the fastening piece. The fastening pieces are in threaded connection with nuts for limiting the corresponding pressing plates. The nuts are located above the corresponding pressing plates. The contact faces of the fastening mechanisms and the circuit board and the contact face of the fixing plate and the circuit board are provided with elastic layers respectively. By means of the technical scheme, on the one hand, wear to the circuit board is lowered by the fastening device in the vibration environment, and on the other hand, displacement, brought by a machine, of the circuit board is lowered through elasticity of the elastic layers, so that the looseness problem of an element on the circuit board is avoided.

Description

technical field [0001] The invention relates to the field of circuit board installation, in particular to a fastening device for circuit boards. Background technique [0002] The circuit board is a kind of carrier of the circuit. It is covered with countless lines. It is convenient to connect various components, and it is easy to make and replace components. Therefore, the stability and durability of the circuit board determine the service life of electronic products. The circuit board Most of them are fixed on the body by using bolts through the mounting holes on the circuit board. The connection between the circuit board and the body is purely hardware. Under long-term vibration, the electronic components on the circuit board are easy to loose and cause breakage between components, especially In industrial control, military industry, aerospace and other fields, encountering harsh vibration environments, there is no guarantee for the protection and reliability of electronic...
