Description
Technical field
The present invention relates to a kind of fixed part, the fixed part that particularly a kind of circuit board is used.
Background technology
The mode that motherboard is fixed in such as the chassis backplane of server or personal computer mostly is the copper post of arranging in pairs or groups and supporting motherboard and be fixed in chassis backplane with screw, in recent years in order to promote the convenience of installing motherboard, so a kind of plastics system and arise at the historic moment without the fixing fixture of instrument.
See also Fig. 1, fixed part 1 comprises hollow housing 10, is located at the flange 11 of these hollow housing 10 bottoms and rotates the pressing part 12 that is incorporated into these hollow housing 10 tops, wherein, this hollow housing 10 has the shell fragment 101 of side direction, this pressing part 12 then is made of a rotating shaft 120 and the both wing portions 121 that extended by these rotating shaft 120 both sides, and this both wing portions 121 has the interval with 10 of this hollow housings.
Can be provided with roughly hole that should hollow housing 10 bottom peripheries in the chassis backplane of server or personal computer (figure does not show), and this fixed part 1 is set out by this hole by the chassis backplane back side, make the flange 11 of the bottom of this shell fragment 101 and this hollow housing 10 bottoms be held on this chassis backplane to periphery that should hole, so that this fixed part 1 is fixed in this chassis backplane.
Then, by the sheathed motherboard in the top of this fixed part 1, it has the thickness that is slightly less than the hole (all not shown) around these hollow housing 10 tops and roughly is matched with this interval H, make this hollow housing 10 these motherboards of top support, and can make this both wing portions 121 suppress end face by rotating this rotating shaft 120 in this motherboard, with this motherboard is fixed in this chassis backplane and and this chassis backplane between keep certain interval.
Though fixed part 1 can tentatively be realized the purpose of fixed host computer plate, but it is because of having both wing portions 121, therefore the hole of being offered on this motherboard must be slightly larger than the area of this both wing portions 121 at least, thereby taken the space on the motherboard, and then the wiring on the restricting host plate, when motherboard was used a plurality of fixed part 1, the occupied space of institute was bigger.
And, the rotating shaft 120 of fixed part 1 can have the effect of best compacting motherboard in rotating 90 degree back both wings 121, the also many limit rotation with rotating shaft in present technique field are rotated between 90 degree now, yet and can't make this rotating shaft 120 be fixed in specific rotational angle, so both wings 121 easily because of vibrations or other external force become flexible.
Moreover the hollow housing 10 of this fixed part 1 only can't limit horizontal the moving of this motherboard for this motherboard of support, therefore makes motherboard produce sliding phenomenon easily when carrying or being subjected to external force.
Therefore, how solving above various shortcoming, is to become the technical problem that present stage demands urgently thinking deeply.
Summary of the invention
The fixed part that provides a kind of circuit board that increases the circuit board wiring degree of freedom to use is provided for shortcoming in view of the above, a purpose of the present invention.
Of the present invention time a purpose is to provide a kind of fixed part that the clear and definite circuit board of operation is used that has.
The fixed part that provides a kind of circuit board with located lateral function to use is provided a further object of the present invention.
For reaching above-mentioned purpose and other purpose, the invention provides the fixed part that a kind of circuit board is used, in order to circuit board is fixed in the chassis backplane of electronic installation, this circuit board has perforate, this fixed part has hollow housing and with the periphery of this circuit board perforate of top support of this hollow housing, it is characterized in that: this hollow housing has first end and the second end in horizontal direction, in this first end, rotate and be combined with a rotating shaft, the top of this rotating shaft exposes to the top of this hollow housing, and the top of this rotating shaft and have the pressing arm that an end extends to this second end certainly, by rotating this rotating shaft the end of this pressing arm is suppressed in this circuit board, thereby this circuit board is fixed on this chassis backplane.
Suppress in motherboard with both wing portions than the fixed part of prior art and to make the perforate of motherboard institute tool must comprise the area of both wings at least, and then influence can the connect up shortcoming of area of motherboard, the fixed part that circuit board of the present invention is used, can reach the effect of fixing circuit board with a pressing arm, so the perforate of circuit board can be dwindled the area of half nearly than prior art.
The top of this hollow housing can have chute with around being sleeved on this rotating shaft, locate concave point and on these protruding rank, can have one, this rotating shaft then side direction is protruding with for the positioning convex point that is positioned this location concave point, when this circuit board is subjected to top institute's support of this hollow housing and make the positioning convex point of this rotating shaft be positioned this location concave point, this pressing arm can the optimum rotation angle be suppressed on this circuit board, and non-ly is difficult for pivot offset through painstakingly pulling.
This hollow housing is in the second end and have a boss that protrudes from this top, the outer rim of this boss can be matched with the partial shape of the perforate of this circuit board, add that this rotating shaft also can be the shape of the perforate other parts that cooperate this circuit board in the part of protruding this hollow housing top, so that being subjected to the support of fixed part of the present invention, this circuit board has horizontal locating effect, to improve the easy traversing defective of motherboard in the prior art.
As from the foregoing, the fixed part that circuit board of the present invention is used can improve the shortcoming of prior art, therefore has industrial utilization.
