Embodiment Construction

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0014] see figure 1 , the embodiment of the present invention includes:

[0015] A circuit board fixing assembly, comprising: a screw head 2 and a stud 4, the stud 4 is arranged concentrically under the screw head 2, the screw head 2 and the stud 4 are an integrated structure, the structure is firm, and the stud 4 4. An external thread is arranged on the outer circle of the lower part, which is convenient to cooperate with the threaded hole on the support seat of the case.

[0016] The circuit board fixing assembly...

Abstract

The invention discloses a circuit board fixing assembly, comprising: a screw head and a stud, the stud is concentrically arranged below the screw head, the circuit board fixing assembly further comprises a vertical support plate, the vertical support The upper end of the plate is provided with a first flat plate perpendicular to the vertical support plate, the lower end of the vertical support plate is provided with a second flat plate parallel to the first flat plate, and the stud extends from the first flat plate to the second flat plate. Below, a compression spring sleeved on the outside of the stud is arranged between the first flat plate and the second flat plate. Through the above method, in the circuit board fixing assembly of the present invention, the second flat plate is pressed on the circuit board to increase the force bearing area and stability, and the compression spring is used to enhance the elastic force of the first flat plate and the second flat plate, so as to reduce the vibration of the chassis and the circuit breaker. The impact of the vibration of the on-board fan on the screw head improves the seismic performance of the circuit board, the fixation is more stable, the installation is fast, and the maintenance is convenient.

Description

technical field [0001] The invention relates to the field of circuit boards, in particular to a circuit board fixing assembly. Background technique [0002] There are a large number of parts and wires on the circuit board, which is highly integrated and easy to use. The use of the circuit board makes the circuit more miniaturized and intuitive, which plays an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances. [0003] For the safety protection and stable operation of the circuit board, the circuit board needs to be fixed in the box for use. The circuit board is usually provided with fixing holes, and the screws are passed through the fixing holes to fix it on the support base. It is easy to install, but the stability is poor, especially the rotation of the fan on the circuit board and the shaking of the box can easily cause the screws to loosen and fall off, affecting normal use of the circuit board.
