Position is corresponding with position of the through-hole 22 on circuit board 20.
Therefore, circuit board 20 can be by two fixing post holes 21 and at least a through-hole 22 is connected and installed in mounting base 10
On, so that the connection of circuit board 20 and mounting base 10 is more firm.
In the present embodiment, the internal threaded column 12 is one, and the through-hole 22 is one.
It is above-mentioned, refer to that circuit board 20 is connected in fixed column 11 by two fixing post holes 21, in addition, a screw 30 is worn
It is installed on an internal threaded column 12 after a through-hole 22 on oversampling circuit plate 20.
Therefore, circuit board 20 can be connected and installed in peace as fixed point by two fixing post holes 21 and a through-hole 22
It fills on seat 10.When installing or removing to circuit board 20, the screw 30 on next internal threaded column 12 only need to be installed or tear open,
Two fixing post holes 21 on circuit board 20 are installed or removed from fixed column 11 again, can be completed circuit board 20 installation or
Disassembly, improves the efficiency of installation or removal.
In the present embodiment, the line of adjacent two fixed columns 11 and an internal threaded column 12 is triangle
Shape.
It is above-mentioned, refer to that the line of two fixed columns 11 and an internal threaded column 12 is triangle, specifically referring to that two are consolidated
On three angles of triangle, each fixed column 11 is equidistant with internal threaded column 12 for fixed column 11 and an internal threaded column 12.
To which two fixed columns 11 and an internal threaded column 12 surround an isosceles triangle.
In the present embodiment, the end of the fixed column 11 is equipped with the bending part for being clamped the fixing post hole 21.
Above-mentioned, one end of fixed column 11 is fixedly connected in mounting base 10, and the end of fixed column 11 refers to fixed column 11
It is not attached to one end of mounting base 10.The end of the fixed column 11 is equipped with the bending part for connecting and fixing post holes 21.Need into
One step illustrates, after fixing post hole 21 is clamped bending part, screw 30 is then passed through through-hole 22 and is installed on internal threaded column 12.Cause
This, fixing post hole 21 will not slide from bending part.Improve the stability that circuit board 20 is installed in mounting base 10.
Further, in the present embodiment, mounting base 10 can be mounting plate, fixed plate, button panel etc..

It is above-mentioned, the groove 111 of post holes 21 is connected and fixed in fixed column 11, specifically, which can be set to fixed column
11 middle part, bottom or top.It should be further noted that after fixing post hole 21 is clamped 11 groove 111 of fixed column, screw
30, which are then passed through through-hole 22, is installed on internal threaded column 12.Therefore, fixing post hole 21 will not slide from fixed column 11.Improve electricity
Road plate 20 is installed on the stability in mounting base 10.
In the present embodiment, the mounting base 10 is equipped with the key pushed, and the circuit board 20 is equipped with and the key pair
The contact switch 23 answered.
It is above-mentioned, specifically refer to mounting base 10 can for key mounting base 10, be equipped with for depressing key, circuit
Contact switch 23 and the key on plate 20 cooperate.Therefore, it when circuit board 20 is installed on mounting base 10, is pressed by lower switch
The on or off of contact switch 23 can be completed in key.
In the present embodiment, the mounting base 10 is PVC mounting base 10.
Above-mentioned, PVC (Polyvinyl chloride) is also known as polyvinyl chloride, is vinyl chloride monomer (vinyl chloride
Monomer, abbreviation VCM) in initiators such as peroxide, azo-compounds;Or Raolical polymerizable is pressed under light, heat effect
The polymer that mechanism is polymerized.Ryuron and vinyl chloride copolymer system are referred to as vinyl chloride resin.
PVC is the white powder of amorphous structure, and the degree of branching is smaller, relative density 1.4 or so, glass transition temperature 77~90
DEG C, 170 DEG C or so start to decompose, and it is poor to the stability of light and heat, in 100 DEG C or more or through a long time exposure in sunshine, Jiu Huifen
It solves and generates hydrogen chloride, and further autocatalysis is decomposed, and causes to change colour, physical mechanical property also declines rapidly, is actually answering
Stabilizer be must be added in improve the stability to light and heat.
In the present embodiment, the fixed column 11 is three, and the fixing post hole 21 is three.
It is above-mentioned, refer to and set on circuit board 20 there are three fixing post hole 21, circuit board 20 is clamped by three fixing post holes 21
In in the fixed column 11 of mounting base 10.In the present embodiment, the fixed column 11 in mounting base 10 is also three, and fixing post hole 21
It is corresponding with position of the fixed column 11 in mounting base 10 in the position on circuit board 20.In addition, screw 30 is passing through circuit board
It is installed on internal threaded column 12 after an at least through-hole 22 on 20.In the present embodiment, internal threaded column 12 is in mounting base 10
Position is corresponding with position of the through-hole 22 on circuit board 20.
Therefore, circuit board 20 can be by three fixing post holes 21 and at least a through-hole 22 is connected and installed in mounting base 10
On, so that the connection of circuit board 20 and mounting base 10 is more firm.
