Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The shock-absorbing structure of a radiation source monitor as shown in fig. 1 to 5 comprises a main cavity 1, two cover plates 4, a shock-absorbing layer 5, a protective sleeve 11 and a fixing plate 12.
The main cavity body 1 is the cavity formula structure of cuboid, the up end of the main cavity body 1 is the opening with terminal surface down, and two apron 4 cover respectively and locate the opening part to it is fixed with apron 4 through the screw. Two sides are provided with draw-in groove 2 about 1 inner wall of main cavity, circuit board 3 forms tight plug with draw-in groove 2 and is connected. The shock-absorbing layer 5 is arranged between the upper surface of the circuit board and the upper wall of the main cavity 1 and between the circuit board and the lower arm of the main cavity 1 to form a protective layer. The shock absorbing layer can absorb external impact to protect the circuit board 3 from being damaged. The shock absorption layer 5 is made of soft elastic materials. Simultaneously in order to avoid 5 influences the heat dissipation of circuit board 3 of buffer layer, 5 adoption graphite heat conduction bubble are cotton for buffer layer.
The shock absorption layer 5 is provided with a plurality of concave parts 7 on one side facing the circuit board 3, and the concave parts 7 are opposite to components on the circuit board 3. The shock absorbing shell 5 can be replaced.
Since the shock-absorbing layer 5 has elasticity, the shock-absorbing layer 5 is slightly larger in volume and is fixed in the main cavity by the elastic tension of the shock-absorbing layer 5. However, since the shock absorbing layer 5 is difficult to insert due to its large volume when it is inserted into the main cavity 1, the shock absorbing layer 5 is provided with a semi-kidney-shaped groove 6 on each side thereof so as to be able to be squeezed into the main cavity 1 to some extent.
