Figure 1 shows that a kind of common heat abstractor combination 50, it comprises a base 51, the lower surface of base 51 is used for contacting to conduct the heat of its generation with electronic component, the upper surface of base 51 is provided with some radiating fins 53, thereby the heat that base 51 conduction are come effectively distributes, the both sides of base 51 are respectively equipped with a pilot hole 54, assembling one is used for heat abstractor combination 50 locked instruments 56 that are fixed on the circuit board in each pilot hole 54, this locked instrument 56 comprises that one can be located in the bolt 57 in this pilot hole 54, one elastic component 58 and a stop ring 59, this bolt 57 comprises a stubborn solid portion 571 that is positioned at base 51 1 sides and a groove 573 and a locking part 575 that is positioned at the base opposite side, this elastic component 58 is set on the bolt 57 and spacing twisting between solid portion 571 and the base 51, this stop ring 59 is attached in the groove 573 of bolt 57, thereby the external screw thread on the locking part 575 of this bolt 57 matches with the screw on the circuit board this heat abstractor combination 50 is locked to this circuit board, and the lower surface of this base 51 is contacted with an electronic component.When but the bolt 57 in this heat abstractor combination 50 needs to change if damage, at first stop ring 59 to be pried open, just the bolt 57 that damages can be pulled down, and then new bolt is installed, at this moment it is good with bolt to need with another new stop ring, not only dismounting is loaded down with trivial details, and maintenance cost is higher.
Summary of the invention
In view of above content, be necessary to provide a kind of heat abstractor combination of easy accessibility.
A kind of heat abstractor combination, it comprises that a base and is assembled to the locked instrument on the described base, described locked instrument comprises a bolt and an elastic component, offered at least one shoulder hole on the described base, be provided with a step in the described shoulder hole, a breach that is communicated to described shoulder hole has been offered at the edge of described base, thereby offered a groove around described bolt on the described bolt and on described bolt, formed a thinner holding division, described holding division passes described breach and enters in the described shoulder hole, described step is placed in the described groove and limits described bolt and shift out from described shoulder hole along the bearing of trend of described shoulder hole, described elastic component is set on the described bolt, and the part of described elastic component stretches in the described shoulder hole and offsets with the edge of described breach and limit described bolt and shift out from described breach.
Compared to prior art, described heat abstractor combination easy accessibility.
Description of drawings
Fig. 1 is the three-dimensional exploded view of existing heat abstractor combination.
Fig. 2 is the three-dimensional exploded view of the utility model heat abstractor combination.
Fig. 3 is the three-dimensional assembly diagram of the utility model heat abstractor combination.
Embodiment
See also Fig. 2, the utility model heat abstractor combination 10 comprises a base 11, base 11 is provided with a lower surface 113 and a upper surface 115 that is used for contacting with electronic component with the heat that conducts its generation, the upper surface 115 of base 11 is provided with some radiating fins 13, thereby the heat that lower surface 113 conduction are come effectively distributes, the both sides of base 11 are respectively equipped with a shoulder hole 14 that runs through base 11, shoulder hole 14 comprises that a macropore 143 and that is positioned at upside is positioned at the aperture 145 of macropore 143 downsides, the edge of aperture 145 forms a step 141 around aperture 145, and the breach 15 that is connected with shoulder hole 14 has been offered at the edge of base 11.
One locked instrument 16 can be assemblied in the shoulder hole 14, and this locked instrument 16 comprises a bolt 17 and an elastic component 18, and in the present embodiment, this elastic component 18 is a Hookean spring.Bolt 17 comprises that a stubborn solid portion 171, that is positioned at the top is positioned at the locking part 175 that the bar portion 172 and of twisting solid portion 171 downsides is positioned at bar portion 172 downsides, the outside of locking part 175 is provided with screw thread, offered a groove 173 around bar portion 172 in the bar portion 172, thereby formed a thinner holding division 177 in bar portion 172, the height of holding division 177 is greater than the height of step 141; Holding division 177 comprises two relative longer side 178 shorter sides 179 relative with two, and the width of shorter side 179 is less than the width of breach 15, and the width of longer side 178 is less than the diameter of aperture 145, but greater than the width of breach 15.
See also Fig. 2 to Fig. 3, when being assembled to locked instrument 16 in the shoulder hole 14, at first elastic component 18 is enclosed within the bar portion 172 of double-screw bolt 17, and the shorter side 179 of relief holding division 177 is relative with breach 15, compression elastic piece 18 makes the upper end of elastic component 18 be against the downside of twisting solid portion 171, allow the lower end of elastic component 18 be higher than the upper surface 115 of base 11, the shorter side 179 of holding division 177 is filled in the breach 15, and allow holding division 177 all pass breach 15 and enter in the aperture 145 of shoulder hole 14, discharge elastic component 18 this moment, the downside of elastic component 18 stretches in the macropore 143 of shoulder hole 14, the lower end of elastic component 18 is against on the step 141, the part that stretches into macropore 143 on the elastic component 18 is kept out at the edge of breach 15, thereby stop the holding division 177 of bolt 17 from breach 15, to shift out, step 141 is placed in the groove 173 simultaneously, thereby restriction double-screw bolt 17 shifts out from shoulder hole 14 along the vertical direction, so locked instrument 16 is by firm being assembled in the shoulder hole 14.
With locked instrument 16 when base 11 is pulled down, rotating bolt 17 in shoulder hole 14, make the shorter side 179 of holding division 177 relative with breach 15, compression elastic piece 18 makes progress, make the lower end of elastic component 18 be higher than the upper surface 115 of base 11, the shorter side 179 of holding division 177 is filled in the breach 15, and allowed holding division 177 all pass breach 15 and from shoulder hole 14, shift out, then locked instrument 16 is pulled down from base 11.
