Fixing component for rotation stopping of circuit board

Abstract

The invention discloses a fixing component for rotation stopping of a circuit board. The fixing component comprises a bolt head and a double-screw bolt, wherein the bolt head is arranged at the top of the double-screw bolt; the fixing component for rotation stopping of the circuit board also comprises a fixing ring through which the double-screw bolt penetrates; a rotation stopping ring is arranged above the fixing ring; a hexagonal through hole corresponding to the bolt head is formed in the rotation stopping ring; a plurality of limiting holes are formed in the upper surface of the fixing ring; limiting posts corresponding the limiting holes are separately arranged at the lower part of the rotation stopping ring; and a non-slip mat is arranged below the fixing ring. By adopting the mode, the fixing component for rotation stopping of the circuit board, disclosed by the invention, has the advantages that the circuit board is fixed by using the bolt head to drive the double-screw bolt for rotating; the non-slip mat is directly contacted with the surface of the circuit board, so that a friction force is increased, and the rotation of the fixing ring and the rotation stopping ring are avoided; and the bolt head is finally screwed into the hexagonal through hole of the rotation stopping ring for fixing, so that the rotation of the double-screw bolt in the use process is prevented, and the stability of the circuit board is improved.

Description

technical field [0001] The invention relates to the field of circuit boards, in particular to a circuit board anti-rotation 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 will easily cause the screws to gradually rotate and loosen. Even fall off, lack of anti-...
