Carriers 320 and 322 of convex extension parts are inserted in the limit 222 of pressing on radiator 20 substrates 22, and the opposite side insertion carrier 320 of the substrate 22 of radiator 20 and protrude out 324 of bars is fixed on the fixed support 30 radiator 20.Be provided with a binding block 326 that has an opening with an end of the body 32 of convex extension part 322 adjacent sides.In addition, on four jiaos in the bottom surface of this fixed mount 30, be respectively equipped with the inner threaded leg 36 that forms.
The metal fastener 40 of one bending comprises an articulated section (figure mark) and one end vertical extent and the press section 42 that goes out from the articulated section.This articulated section is articulated in 322 of the carrier 320 of fixed mount 30 1 bodies 32 and convex extension parts, is formed with a pressure section (figure does not show) on this articulated section.This fastener 40 also comprises the button hook 44 of a terminal extended bending of self-pressing portion 42, binding block 326 on this button hook 44 and fixed mount 30 bodies 32 fastens, and make pressure section on the articulated section tightly be pressed on the pressing on the limit 222 of substrate 22 of radiator 20, and make radiator 20 more firm being fixed on the fixed mount 30.
Please further consult Fig. 3, these radiator rear panel combination 60 backboards 66 that comprise an elastomeric pad that contacts with circuit board 62, are positioned at an elastic support 64 of elastomeric pad 62 belows and accept this elastic support 64.
This backboard 66 is a rectangular horizontal metallic plate, is provided with two adjacent through holes 660 in the middle, protrudes out the side that a button hook 662, one arc lugs 664 are arranged at through hole 660 upwards, in the same way closing on each through hole 660 place.The relative both sides of these backboard 66 through holes 660 are respectively arranged with the intensity that a ribs 665 is used for strengthening backboard 66.Four installing holes 668 are separately positioned on four jiaos of backboard 66 and are corresponding with the through hole 14 of circuit board 10.
This elastomeric pad 62 is arranged between circuit board 10 and the elastic support 64, to contact with circuit board 10.This elastomeric pad 62 is a ring slice, by four bodies 620 around forming.Two bodies, 620 connections form an arc linkage section (figure mark) respectively, and the middle part of each body 620 is provided with an arc notch (figure is mark), and the relative both sides of each arc notch are respectively arranged with a downward barrier rib 6202.One stator 624 is formed between the two relative arc linkage sections in the elastomeric pad 62.This stator 624 comprises two linking arms 6240 that connect the arc linkage section and the fixed part 6242 that is positioned at two linking arms, 6240 middle parts.This fixed part 6242 is provided with button hook 662 corresponding two button holes 6244 with backboard 66, and a side of fixed part 6242 and linking arm 6240 junctions is provided with the arc lug 664 corresponding breach 6246 on the backboard 66.Two linking arms 6240 at these stator 624 two ends slightly make this stator 624 form an arcuate structure to lower recess, cooperate with button hook 662 and arc lug 664 on the backboard 66 and be convenient to fixed part 6242.
This elastic support 64 is arranged at backboard 66 middle parts, by four bodies, the 640 continuous annular frameworks that form, the shape of the shape of this annular framework and elastomeric pad 62 is roughly the same, body 640 connecting places all form an arc linkage section (figure is mark not), four feets 644 extend to form downwards from the middle part of each body 640, and the width of each feet 644 is little than the arc notch of elastomeric pad 62.
Please consult Fig. 2 once more, when being assembled in elastic support 64 on the backboard 66, earlier elastic support 64 is positioned over the middle part of backboard 66, its four feets 644 are contacted with backboard 66 stably, again elastomeric pad 62 is sticked above elastic support 64, make the barrier rib 6202 of its relative both sides of arc notch be crossed on feet 644 both sides of elastic support 64, this barrier rib 6202 is used to limit elastomeric pad 62 along 644 liang of side shiftings of feet.Two button hooks 662 on two button holes 6244 of the fixed part 6242 on the stator 624 of elastomeric pad 62 and the water sheet plate body 66 fasten, arc lug 664 on the backboard 66 is resisted against in the breach 6246 on the stator 624, makes elastic support 64 firm being positioned on the backboard 66.
When radiator rear panel combination 60, circuit board 10 and radiator 20 are fitted together by fixed mount 30, four legs 36 of fixed mount 30 pass the through hole 14 of circuit board 10 and the through hole 668 of backboard 66 screws with screw (figure does not show) again, and make the elastomeric pad 62 of radiator rear panel combination 60, four feets 644 of elastic support 64 produce strain, thereby radiator 20, circuit board 10 and radiator rear panel combination 60 are installed in together.At this moment, the below that the elastomeric pad 62 of radiator rear panel combination 60 and elastic support 64 are positioned at circuit board 10, and replace on circuit board 10 by the upper surface of elastomeric pad 62.Because elastomeric pad 62 and circuit board 10 be for face contact, more traditional radiator rear panel combination, contact area increase, circuit board 10 and elastomeric pad 62 contact positions stressed even, deformation quantity is little.
