Two tabs 212 extend up from the bottom wall 21, adjacent to the sidewalls 23, respectively. Each tab 212 is parallel to the sidewalls 23, and forms a hook 213 on a first end of the top of the tab 212. The hook 213 extends toward a second end of the top of the tab 212 away from the first end. Two fasteners 231 respectively protrude from inner surfaces of the sidewalls 23, away from the tabs 212. An opening 233 is defined in each sidewall 23 adjacent to the corresponding fastener 231. A notch 235 is defined in the top of each sidewall 23 above the corresponding opening 233.
Each fixing device 30 includes a bracket 40, a resilient plate 50, a handle 60, and a pin 70. In the embodiment, the pin 70 is a spring pin.
The bracket 40 includes a rectangular main body 41, a bending portion 43 extending out and down from the bottom of the main body 41, a fixing plate 45 perpendicularly extending in from a first end the bottom of the bending portion 43, and a supporting plate 47 extending down and in from a second end of the bottom of the bending portion 43 away from the fixing plate 45. Two fixing holes 414 are defined in the main body 41 adjacent to opposite ends of the main body 41, respectively. Two pivot holes 412 are defined in the main body 41 adjacent to two top corners of the main body 41, respectively. Two protrusions 416 are formed on an outer surface of the main body 41, between the fixing holes 414. A post 451 defining a threaded hole is formed on a middle of the fixing plate 45.
The resilient plate 50 is stamped out of sheet metal, and includes a fixing portion 51, a connecting portion 53 slantingly extending outwards from an end of the fixing portion 51, and a resilient arm 55 slantingly concaving inwards from an end of the connecting portion 53 away from the fixing portion 51. A through hole 512 is defined in the fixing portion 51 adjacent to the connecting portion 53. A projection 514 perpendicularly extends from an inner surface of the fixing portion 51 away from the connecting portion 53. A latching hole 551 is defined in the resilient arm 55 away from the connecting portion 53.
The handle 60 includes two opposite side plates 61, and a top plate 63 connected between tops of the side plates 61. Each side plate 61 includes a first plate 613, a second plate 611, and a slot 612 defined between the first and second plates 613 and 611. The bottom end of each slot 612 extends through the bottom of the corresponding side plate 61. Each second plate 611 defines a pivot hole 614 away from the corresponding slot 612, and a positioning hole 618 adjacent to the corresponding slot 612. A block 619 extends from an inner surface of each second plate 611 towards the opposite second plate 611 adjacent to the corresponding pivot hole 614. A concave portion 616 is formed on an outer surface of each first plate 613.
Referring to FIGS. 1 and 2, to assemble the fixing devices 30, the resilient plates 50 are respectively arranged at the outer sides of the brackets 40. The projection 514 of one of the resilient plate 50 is extended through the fixing hole 414 of one of the corresponding brackets 40 adjacent to the fixing plate 45, and is riveted to the corresponding bracket 40. The projection 514 of the other resilient plate 50 is extended through the fixing hole 414 of the other bracket 40 adjacent to the supporting plate 47, and is riveted to the other bracket 40. Thereby, the fixing portions 51 of the resilient plates 50 are fixed to the outer sides of the brackets 40, respectively. The protrusions 416 of each bracket 40 adjacent to the corresponding projection 514 is extended through the through hole 512 of the corresponding resilient plate 50, and exposed out of the corresponding resilient plate 50. Each resilient arm 55 gradually approaches the main body 41 of the corresponding bracket 40 from an end adjacent to the corresponding connecting portion 53 to an opposite end away from the corresponding connecting portion 53.
The top corner of each main body 41 adjacent to the corresponding projection 514 is inserted into a space between the blocks 619 of the corresponding handle 60, to allow the pivot hole 412 adjacent to the projection 514 to align with the pivot holes 614 of the corresponding handle 60. A pin 70 is extended through the pivot holes 614 and 412 of the handle 60 and bracket 40 of each fixing device 30, to rotatably connect the handle 60 to the bracket 40.
Referring to FIG. 4, to assemble the motherboard 10, the fixing devices 30 are oppositely arranged, to allow each of the opposite sides 11 of the motherboard 10 to be sandwiched between the supporting plate 47 and the fixing plate 45 of the corresponding bracket 40, and to allow the through holes 13 of the motherboard 10 to align with bottoms of the threaded holes of the posts 451 of the brackets 40, respectively. Two screws (not shown) are respectively extended through the through holes 13, and engage in the corresponding threaded holes of the posts 451, to fix the opposite sides 11 of the motherboard 10 to the fixing plates 45 of the brackets 40, respectively. The motherboard 10 and the fixing devices 30 are placed in the chassis 20. The hooks 213 are extended through the corresponding slots 15 of the motherboard 10, to allow the motherboard 10 to be supported on the tabs 212. The motherboard 10 is slid towards the first ends of the tabs 212, until the motherboard 10 is stopped by the hooks 213. The hooks 213 engage with the top of the motherboard 10. The latching holes 551 of the resilient plates 50 of the fixing devices 30 align with the fasteners 231 of the sidewalls 23 of the chassis 20, respectively.
Referring to FIGS. 3 and 4, the handles 60 are rotated towards the corresponding brackets 40. To each fixing device 30, the fixing portion 51 of the resilient plate 50 and a first end of the corresponding bracket 40 connected to the fixing portion 51 are inserted into a space between the second plates 611 of the corresponding handle 60, the connecting portion 53 of the resilient plate 50 is inserted into the slot 612 on an outer side of the corresponding handle 60, and the first plate 613 on the outer side of the handle 60 is inserted into a space between the bracket 40 and the resilient arm 55 of the resilient plate 50. The resilient arm 55 of each resilient plate 50 is deformed towards the corresponding sidewall 23 by the corresponding first plate 613. The fastener 231 of each sidewall 23 engages in the latching hole 551 of the corresponding resilient arm 55. Thereby, the fixing devices 30 and the motherboard 10 are fixed to the sidewalls 23 of the chassis 20. A second end of each bracket 40 aligning with the corresponding resilient arm 55 is inserted into a space between the first plates 613 of the corresponding handle 60. The protrusion 416 of each bracket 40 engages in the positioning hole 618 of the second plate 611 on an outer side of the corresponding handle 60, to lock the handle 60 to the corresponding bracket 40. The concave portion 616 on an outer side of each handle 60 is aligned with the notch 235 of the corresponding sidewall 23. The resilient arm 55 of each resilient plate 50 is aligned with the opening 233 of the corresponding sidewall 23.
Referring to FIG. 5, to detach the motherboard 10 from the chassis 20, an operator inserts fingers into the notches 235 of the sidewalls 23 and operates the concave portions 616 of the handles 60, to rotate the handles 60 upwards. The protrusions 416 of the brackets 40 disengage from the positioning holes 618 of the corresponding handles 60. The operator inserts fingers into the openings 233 of the sidewalls 23 and presses the resilient arms 55 towards the corresponding brackets 40, to allow the resilient arms 55 to disengage from the fasteners 231 of the corresponding sidewalls 23. The resilient arms 55 are restored inwards. The motherboard 10 is slid to disengage from the hooks 213 of the chassis 20. Thereby, the motherboard 10 and the fixing devices 30 can be detached from the chassis 20, and the motherboard 10 is ready to be detached from the fixing devices 30.
