Embodiment
See also Fig. 1, Fig. 1 illustrates the synoptic diagram according to a kind of circuit board fixing mechanism 100 in one embodiment of the invention.Circuit board fixing mechanism 100 is please consulted Fig. 5 in the lump in order to circuit board 200 is fixed in the cabinet of desktop PC, industrial computer or server host, and Fig. 5 illustrates circuit board fixing mechanism 100 circuit board 200 is fixed in the synoptic diagram in the cabinet.As shown in Figure 5, cabinet can comprise housing 102 and loam cake 110, and wherein, housing 102 comprises base plate 102a and side plate, and side plate is positioned at the edge of base plate 102a and vertical with base plate.In Fig. 5, side plate comprises side plate 102b and side plate 102c, and side plate 102b and side plate 102c lay respectively at base plate 102a both sides of the edge, and it against each other and vertical with base plate 102a respectively.
As shown in Figure 1, circuit board fixing mechanism 100 of the present invention comprises locating part 104, drive-connecting shaft 106 and rotational structure 108.Locating part 104 is arranged on the base plate 102a; It is one group configuration that locating part 104 can be two C font structures; Two C font structures are arranged at the both sides of base plate 102a respectively, form the position of a locating slot 104a in order to restricting circuits plate 200 between two C font structures.
Drive-connecting shaft 106 is positioned on the side plate (side plate 102b); Rotational structure 108 with the side plate 102b that is arranged at the right side in Fig. 1 is an example; Be merely illustrational convenience, in like manner be positioned at the framework that also can have equality on the side plate (side plate 102c) of opposite side, below provide an explanation no longer especially.
One end of rotational structure 108 is articulated on the drive-connecting shaft 106, and the other end of rotational structure 108 has stop section 108a.In this embodiment, stop section 108a can be formed through bending by the part of rotational structure 108, and in the practical application, rotational structure 108 can adopt a panel beating material, and the panel beating material forms the shape of rotational structure 108 through cutting, punching press, bending and/or soldering.
The operating personnel of manufacturer the user is provided with or the process of populated circuit board 200 in; At first; Circuit board 200 can from top to bottom vertically insert the space between two C font structures of locating part 104, and promptly the feather edge 200a of circuit board 200 can get into locating part 104 formed locating slot 104a.
Then, the operating personnel can push rotational structure 108 near stop section 108a part, and rotational structure 108 is rotated down by discharging angle (as shown in Figure 1).Then please consult Fig. 2 and Fig. 3 in the lump, it illustrates the synoptic diagram when rotational structure 108 rotates to fixed angle in the circuit board fixing mechanism 100.As shown in Figure 2, on the top edge 200b of circuit board 200, rotational structure 108 went to fixed angle and circuit board 200 was close proximity on the base plate 200a this moment up to stop section 108 in rotational structure 108 sustainable rotations.
Then see also Fig. 4, it illustrates the synoptic diagram that is assembled to housing 102 last time circuit board fixing mechanism 100 when loam cake 110.As shown in Figure 4, in this embodiment, when rotational structure 108 has gone to fixed angle, can then loam cake 110 be assembled on the housing 102.When loam cake 110 is accomplished assembling; Loam cake 110 just can with rotational structure 108 butts; And rotational structure 108 is sticked in this fixed angle; Press on base plate 102a so as to feather edge 200a and go up and circuit board 200 is fixed between stop section 108a and the base plate 102a, can not rotate the problem that structure 108 is become flexible circuit board 200.In the present embodiment, utilize the original loam cake 110 of General System cabinet to fix the anglec of rotation of rotational structure 108, do not need extra trip, stuck point or other structure, escapable cost.In addition, when the user removes loam cake 110, just can easily circuit board 200 be disassembled, very convenient in the use.
What must specify is; As shown in Figure 4, wherein when circuit board 200 was fixed on the base plate 102a, circuit board 200 still maybe be at a distance of clearance height G1 with loam cake 110; In the present embodiment, the width of the stop section 108a of rotational structure 108 can design by corresponding clearance height G1.The vertical width of stop section 108a approximates clearance height G1 greatly, can obtain the fixed effect of preferable circuit board 200.
In addition, the circuit board fixing mechanism 100 in the present embodiment can reach desirable fixing effect by three direction of principal axis difference fixing circuit board 200.As shown in Figure 3, locating part 104 formed locating slot 104a have linear direction, and two C font structures of locating part 104 make circuit board 200 limited can't moving along first direction D1 (in Fig. 3, being fore-and-aft direction) in order to restricting circuits plate 200.
On the other hand; The stop section 108a of rotational structure 108 and base plate 102a then seize circuit board 200 on both sides by the arms by both sides up and down; Make it in order to restricting circuits plate 200 and can't move (vertical direction about being) along second direction D2 in Fig. 3, wherein first direction D1 is vertical with second direction D2.
In addition, as shown in Figure 5, the side plate 102b of side plate and side plate 102c are respectively against the two side ends of circuit board 200.That is to say that side plate 102b and side plate 102c and then restricting circuits plate 200 make it and can't move (in Fig. 5, being the left and right horizontal direction) along third direction D3.Wherein, first direction D1, second direction D2 and third direction D3 are vertical respectively each other.
See through first direction D1, second direction D2 and three axial spacing fixing of third direction D3; Just can circuit board 200 closely be fixed on the ad-hoc location on the base plate 102a; And when rotational structure 108 is outwarded winding, also can easily circuit board 200 be unloaded.
In sum, the present invention proposes a kind of circuit board fixing mechanism, utilizes rotational structure easily circuit board to be fixed on the casing.Rotational structure can be articulated on the side plate of cabinet housing and utilize rotation mode to push fixing circuit board, and it has the characteristic of the more convenient application of force.And this fixed mechanism can fill the space that part is utilized the side plate of housing, does not need to fight for or take the space in the chassis backplane portion with other primary clustering (like motherboard).
Though the present invention discloses as above with embodiment; Right its is not in order to limit the present invention; Anyly be familiar with this art; Do not breaking away from the spirit and scope of the present invention, when can doing various changes and retouching, so protection scope of the present invention is as the criterion when looking the scope that appending claims defines.
