Problems solved by technology

Although this method of fixing the circuit board solves the problem of disassembling the circuit board, due to the use of the bump and pivot structure, the structure of the holding device requires high precision. In addition, when the bump is in a locked state, The pivot will be subjected to a large shear force, but due to the limitation of the structural space, it is impossible to make the size of the pivot too large. Therefore, this buckling device is prone to fracture or deformation of the pivot, which will cause the entire circuit board to buckle. holding device failure

Embodiment Construction

[0021] refer to figure 1 The present invention is described in further detail.

[0022] Such as figure 1 As shown, the housing 1 is a frame structure for accommodating the circuit board 2 inside. It can be a closed frame surrounded by four sides, or an open frame with only two opposite side walls 3. The closed frame is beneficial to protect the circuit. As for the board 2, the open frame is good for heat dissipation of the circuit board 2.

[0023] One or more pairs of channels 4 are correspondingly provided on the inner sides 5 of the two side walls, and a positioning hole 10 is provided beside each channel 4 . The channel 4 and the side wall 3 may adopt an integrated structure, or may adopt a split structure, and be fixedly connected to the side wall 3 by screws, riveting, welding or other connection methods. Each pair of slots 4 can accommodate a circuit board. In this way, multiple circuit boards can be collectively installed in the casing 1 .

Abstract

Being matched to circuit board, slots are setup at two sidewalls of case for accommodating the circuit board. The said circuit boards are inserted on and connected to the slots. Characters are that a fastening clip is setup at an insertion edge of circuit board or two pieces of fastening clips are setup at insertion edges of circuit board. Elastic arm is at side face of the fastening clip. There are locating holes on sidewall of the case for accommodating elastic arms. Through elastic arms being fastened on the locating holes, the circuit board is fixed on the case. Advantages are: reasonable fixing method, easy of operation, and convenient to disassemble circuit board.

Description

technical field [0001] The invention relates to a connection and fixing method, in particular to a method for fixing a circuit board. Background technique [0002] Circuit boards are more and more widely used in people's life, work and study. In the past, the circuit board was connected and fixed by screw connection to fix the circuit board. However, the use of screws to fix the circuit board will inevitably cause the cooperation between the screw and the screw hole to become loose during the repeated disassembly process, which will affect the circuit board. The fixation of the circuit board will reduce the shock resistance and reliability of the whole machine because the circuit board cannot be firmly fixed. [0003] In order to overcome the above-mentioned defects, people have invented a new circuit board fixing method. In this method, the circuit board is restricted in the channel by adopting a channel structure, and the channels are respectively arranged on the two sid...
