PCB mounting and fixing apparatus convenient to mount and dismount

Abstract

The invention relates to the technical field of a PCB, and discloses a PCB mounting and fixing apparatus convenient to mount and dismount. The PCB mounting and fixing apparatus comprises a shell; a left fixed plate is fixedly connected with one side of an inner cavity of the shell and a right fixed plate is fixedly connected with the other side of the inner cavity of the shell; connecting plates are fixedly connected with the upper and lower ends of the inner cavity of the shell respectively; an auxiliary sliding groove is formed in one end of each connecting plate; an auxiliary sliding blockis glidingly connected in the interior of each auxiliary sliding groove; a sliding plate is fixedly connected with one side of each auxiliary sliding block; and a fixing apparatus is fixedly connectedwith one side of each connecting plate. The PCB mounting and fixing apparatus convenient to mount and dismount is provided with mounting apparatuses; inner rods are fixedly connected with the two sides of the PCB in a sleeving manner; the inner rods are arranged in outer rods in a sleeving manner, so that the length of the PCB can be adjusted conveniently; when the PCB is mounted, the PCB is adjusted to a proper length firstly, then a main sliding block is aligned to a main sliding groove, and the main sliding groove drives the main sliding block to slide, so that a clamping block can be clamped in a clamping groove when the PCB enters the interior of the shell, thereby realizing fixing and mounting of the PCB; and convenience in mounting and dismounting also can be achieved.

Description

technical field [0001] The invention relates to the technical field of PCB boards, in particular to a fixing device for facilitating the installation of PCB boards. Background technique [0002] The PCB board is a printed circuit board, also known as a printed circuit board, and is a provider of electrical connections for electronic components. Its development has a history of more than 100 years. Its design is mainly layout design. The main advantage of using circuit boards is that it greatly reduces wiring and assembly errors, improves automation level and production labor rate, and can be divided according to the number of circuit board layers. For single-sided board, double-sided board, four-layer board, six-layer board and other multi-layer circuit boards. [0003] Most of the existing PCB board fixed installation structures cannot adjust the space where the PCB board is installed, which will lead to the inability to apply the use of PCB boards with different area spec...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a fixing device for PCB board installation, which has the advantages of being easy to disassemble, adapting to the installation of PCB boards of different sizes, and strengthening and stabilizing. Disassembly and assembly are more cumbersome and the scope of application is lower
