Description
Technical field
The utility model is related to PCB circuit board fields, and in particular to a kind of multilayer circuit board that anti-seismic performance is good.
Background technology
PCB circuit board, also known as printed circuit board are cut into certain size using insulation board as base material, at least have one thereon
A conductive pattern, and it is furnished with hole（Such as component hole, fastener hole, plated through-hole）, it is used for replacing previous device electronic component
Chassis, and realize the interconnection between electronic component.Carrier of the pcb board as electronic component is widely used
In various electronic equipments.
For multilayer circuit board, especially as the multilayer circuit board of master board, in the circuit commonly used in complexity, on
The face meeting multiple electronic components of integrated installation, are then fixedly mounted on by the screw hole of surrounding a little in the shell of equipment, however,
If electronic equipment falls to ground or severe jolt vibrations occurs, the electronic component on circuit board may be caused to loosen,
Desoldering is damaged so as to cause electronic equipment.
Utility model content
The purpose of this utility model is to provide a kind of multilayer circuit board that anti-seismic performance is good, to prevent circuit board because acute
Violent shock is dynamic and the electronic component of circuit board top is caused to loosen.
The utility model in order to solve its technical problem used by technical solution be：
A kind of multilayer circuit board that anti-seismic performance is good comprising be set to the wiring area at circuit board center and be set to
The bradyseism area of circuit board periphery, the bradyseism area include the hollow slots of multiple mounting holes and multiple strips, from the circuit board
Edge to the center of the circuit board, the length of the hollow slots of the multiple strip gradually increases.
Further, it is provided with elastic washer in the mounting hole.
Further, the circuit board is rectangle, and the mounting hole is set to rectangular four corners.
Further, the hollow slots of the multiple strip are parallel to every one side of the circuit board.
Further, the surface soldered in the wiring area has multiple electronic components.
Compared with prior art, the good multilayer circuit board of the anti-seismic performance of the utility model is being set to circuit board center
Wiring area periphery setting bradyseism area, the bradyseism area includes the hollow slots of multiple mounting holes and multiple strips, when
When strenuous vibration occurs for circuit board, the bradyseism area can gradually deform upon and absorb the vibrations and generate from outside to inside first
Energy, to slow down the impact suffered by the wiring area at protection circuit plates center；From the edge of the circuit board to the electricity
The length at the center of road plate, the hollow slots of the multiple strip gradually increases, so that the energy absorbed gradually increases
Add, prevents the bradyseism area from damaging；In addition, elastic washer is arranged in the mounting hole, it can further slow down strenuous vibration pair
Influence caused by the circuit board.
Description of the drawings
Fig. 1 is the structural schematic diagram of the good multilayer circuit board of anti-seismic performance of the utility model.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
The realization of the utility model is described in detail below in conjunction with specific embodiment.
As shown in Figure 1, the utility model embodiment provides a kind of multilayer circuit board that anti-seismic performance is good comprising be set to
The wiring area 1 at circuit board center and the bradyseism area 2 for being set to circuit board periphery, the bradyseism area 2 include multiple mounting holes
21 and multiple strips hollow slots 22.The circuit board is rectangle, and the hollow slots 22 of the multiple strip are arranged in parallel
In every one side of the circuit board.It is engraved from the edge of the circuit board to the center of the circuit board, the multiple strip
The length of empty slot 22 gradually increases.When strenuous vibration occurs for circuit board, the bradyseism area 2 can gradually occur from outside to inside first
Deformation and absorb it is described vibrations generate energy, to slow down the impact suffered by the wiring area 1 at protection circuit plates center.From
The length at the edge of the circuit board to the center of the circuit board, the hollow slots 22 of the multiple strip gradually increases, from
And can so that the energy absorbed is stepped up, prevent the bradyseism area from damaging
The mounting hole 22 is set to four corners of the circuit board.The mounting hole 22 be used for on electronic product
Bolt arrangement is mutually fixed.22 inside of the mounting hole is provided with elastic washer（It is not shown）, so as in the electronic product
The energy that vibrations are absorbed when strenuous vibration, prevents the circuit board to be damaged.
Further, the surface soldered in the wiring area 1 has multiple electronic components 11, to realize the circuit board
Function.
In conclusion the good multilayer circuit board of the anti-seismic performance of the utility model is in the circuit cloth for being set to circuit board center
The periphery setting bradyseism area in line area, the bradyseism area includes the hollow slots of multiple mounting holes and multiple strips, when circuit board is sent out
When raw strenuous vibration, the bradyseism area can gradually deform upon and absorb the energy that the vibrations generate from outside to inside first, from
And slow down the impact suffered by the wiring area at protection circuit plates center；In from the edge of the circuit board to the circuit board
The length of the heart, the hollow slots of the multiple strip gradually increases, so that the energy absorbed is stepped up, prevents institute
State the damage of bradyseism area；In addition, elastic washer is arranged in the mounting hole, it can further slow down strenuous vibration to the circuit board
Caused by influence.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
