Abstract
The present invention proposes a kind of installation in the housing of double-layer circuit board and fixing means, and described installing component is mainly by upper shell, lower housing, the compositions such as upper layer circuit board, lower circuit plate and mounting screw.It is characterized in that：Upper layer circuit board is shored upwards by lower housing, and lower circuit plate is shored downwards by upper shell, and the support column of lower housing is staircase structural model and to pass through lower circuit plate；Upper-lower casing is directly connected to by four screws；Supporting accessory is not needed between upper layer circuit board and lower circuit plate.This method can effectively remove the standing finish between two-tier circuit plate.And quickly and effectively it can install or dismantle.So that production process is reduced, production efficiency improves.
Description
Technical field
The present invention is mainly suitable for the installation of a kind of instrument or electronic equipment internal circuit board and fixing means.Because
Can all there are one or two even more control circuit boards inside instrument and control electronics, these control circuit boards must
It must want firm with shell to be fixed together.When the installation parallel with surface of shell of odt circuit plate face, often have very
More screw hole can support upper and lower plates, installation very cumbersome with four intermediate sleeves.It, can be with using such fixing means
It is effective to reduce mounting hole and screw, and do not need sleeve and be supported.It is easy for assemble or unload, it is readily replaceable, facilitate repair.
Background technology
Can all there are even multiple circuit boards, the installation direction of circuit board in common instrument or electronic equipment internal
It is also many with mode, it is generally divided into parallel installation and right angle setting two ways.When circuit plate face and shell front vertical are installed
When, some card slots can be designed in the both sides of shell, circuit board is slid into from card slot, and in tail portion squeeze admittedly
It is fixed.When circuit plate face and shell frontoparallel are installed, some discontinuous wedge-shaped projections can be done in shell rim, it will be electric
Road plate pushing, which is stuck in below wedge-shaped projection, to be fixed.Or it is directly locked at the back side of shell with screw.When have two layers with peace
When the parallel circuit board in dress face needs installation, between upper and lower plates other than communication link wiring, it can be fixed to each other without other
Position.Traditional method can all be expected being carried out with the copper stud of four appropriate height respectively on four angles of two-tier circuit plate
Support, this method is unquestionably feasible.But in producing installation process, needs that four copper studs are installed, also to pacify
Four screws are filled, many processing and installation processes are undoubtedly increased.Using the method for this patent introduction can reduce upper and lower plates it
Between support copper stud.Directly two layers of plank is fixed on shell, it is only necessary to four screws can by double-layer circuit board and
Shell is firm to be fixed together.It can very easily mount and dismount, and reduce process, improve production efficiency.
Invention content
In view of the above shortcomings of the prior art, the present invention proposes the installation and fixation of a kind of double-layer circuit board in the housing
Method.This method can effectively remove the standing finish between two-tier circuit plate.And can quickly and effectively install or
Dismounting.So that production process is reduced, production efficiency improves.
The present invention solves its technical problem, and used technical solution is：A kind of installation of double-layer circuit board in the housing
And fixing means, described installing component is mainly by upper shell, lower housing, upper layer circuit board, lower circuit plate and installation
The compositions such as screw.It is characterized in that：Upper layer circuit board is shored upwards by lower housing, and lower circuit plate is pushed up downwards by upper shell
The support column of support, lower housing is staircase structural model and to pass through lower circuit plate；Upper-lower casing is directly connected by four screws
It connects；Supporting accessory is not needed between upper layer circuit board and lower circuit plate.
Compared with prior art, the beneficial effects of the invention are as follows：
（1）It the installation of this method and uses and can make the simpler convenience of the installation of double-layer circuit board in the housing, reduce peace
Cartridge screw and installation procedure.
（2）It the installation of this method and uses so that the support of two-tier circuit plate fully relies on shell, without at two layers
Increase supporting accessory among circuit board.
Description of the drawings
Fig. 1 is the structure chart designed by the present invention.
Specific implementation mode
As shown in Figure 1, needing the lower circuit plate made consistent with the size of layer shell（Including installation interval size）,
And the edge of the non-position of mounting hole of the size of upper layer circuit board reduces 5mm than lower circuit plate border width, in this way may be used
So that layer shell edge lug boss passes through upper layer circuit board.The quadrangle of two circuit boards is required for four mounting holes of setting, upper layer
The mounting hole of circuit board is smaller than the mounting hole of lower circuit plate, and the mounting hole of lower circuit plate needs and the ruler of lower housing boss
It is very little to be consistent so that lower circuit plate is just placed on the cylinder step boss of lower housing.Double-layer circuit board is installed into shell
When body, upper layer circuit board is first placed in upper shell, and then lower circuit plate is placed on the edge step boss of layer shell,
It needs that mounting hole is kept to be aligned with the mounting hole of case top.Lower housing is passed through to the mounting hole of lower circuit plate, lower housing again
Four column tops just shore layer circuit board.Then lower housing is directly rushed across with screw to be locked on upper shell.
Reference numeral title
4 lower circuit plate of layer circuit board, 5 screw on 1 upper shell, 2 upper shell side boss 3
6 be 7 lower housing of shell cylindricality step, 8 mounting hole.
