Position muscle 121, which can be, to be arranged on pedestal rear wall 5 or bottom plate 4.It, will in circuit board mounting box when mounting circuit boards 100
The rear of circuit board 100 is caught between rear upper limit muscle 122 and rear lower limit muscle 121, until the leading edge of circuit board 100 is snapped into
Between the end of elastic cantilever fastener 8 and front lower limit rib 11.At this point, circuit board 100 is clamped and fastened on circuit board mounting box
In.In some embodiments, elastic cantilever fastener 8, front lower limit rib 11, rear lower limit muscle 121 and rear upper limit muscle 122
The quantity being arranged in circuit board mounting box is respectively at least two.In preferential embodiment, which has from downward
The leading edge of circuit board 100 is pressed downward by inclined guide part 81 along guide part 81, keeps operation more convenient.
The embodiment gone out as shown in Figure 1A there is also variation, as elastic cantilever fastener 8 can be set pedestal front side wall 7,
On pedestal rear wall 5, chassis left side wall 14 and at least one party or two sides in base right side wall 18, can also it reach and aforementioned bullet
The identical effect of embodiment that property cantilever fastener 8 is provided only on pedestal front side wall 7.
Continuing with referring to Figure 1A and Figure 1B, in one embodiment, upper cover front side wall 20 is set below upper cover rear wall
22, correspondingly, pedestal front side wall 7 is set above pedestal rear wall 5, and beneficial effect obtained, which is arranged such, is, by
It is arranged in pedestal rear wall 5 relatively low, the rear of circuit board 100 is enabled to be easier to be snapped into rear upper limit muscle 122
Between rear lower limit muscle 121, so that the installation of circuit board 100 is more convenient.Forward and backward 5,7 height of side wall of pedestal is different simultaneously
Setting so that forward and backward protruding pin 21,23 will not be blocked mutually during installation, further simplify pedestal 2 and upper cover 3 installed.
In one embodiment, it is additionally provided with notch 25 on upper cover left side wall 24 and upper cover right side wall 27, notch 25 allows
Winding displacement passes through base side wall.With embodiment shown in Figure 1A and Figure 1B there is also changing, as notch 25 can be setting
On at least one party in chassis left side wall 14, base right side wall 18, upper cover left side wall 24, upper cover right side wall 27.
It is first that the left and right sidewall of upper cover 3 and pedestal 2 is aligned with each other when needing to be installed pedestal 2 and upper cover 3, with
Side wall pushes upper cover 3, until convex ribs 26 are snapped among catching groove 16, while multiple preceding protruding pins 21 be inserted into multiple preceding pin holes 9,
Protruding pin 23 is inserted into multiple rear pin holes 13 after multiple, and upper cover 3 and pedestal 2 are directly firmly fixed.Upper cover 3 is installed with pedestal 2
Complete state is as shown in Figure 3.At this point, upper cover front side wall 20 is located at the inside of pedestal front side wall 7, upper cover rear wall 22 is located at pedestal
The outside of rear wall 5；Upper cover left side wall 24 is located at the outside of chassis left side wall 14, and upper cover right side wall 27 is located at base right side wall 18
Outside.
