Portion 12 and a kink 14 being bent to form by the top of this connecting portion 12.
This back plate 20 is provided with some flutings 201.This back plate 20 is provided with a supporting part in the bent over of these flutings 201
21, this back plate 20 forms a decorating plate 23 in the top of this supporting part 21.The tabs 24 that decorating plate 23 projection two is parallel, tabs 24
Middle part be provided with opening, the top of two tabs 24 is bent respectively to form a banking stop 242 relatively.Back plate 20 is in the middle of two tabs 24
A through hole 25 is offered in the position of central authorities, and in upside projection one retainer 252 of through hole 25, the downside projection one of through hole 25 is upwards
The L-shaped limiting section 254 of bending.The open space of the decorating plate 23 position correspondence tabs 24 between two tabs 24 arranges four pivots
Rotor 26, two pivot sheets 26 in the middle of it are positioned at the left and right sides of through hole 25.Each pivot sheet 26 offers a pivoting hole 262.
The left and right sides of through hole 25 is respectively provided with a convex bridge 27 in every two positions pivoted between sheet 26.Decorating plate 23 is in two tabs 24
Outside is respectively provided with a card 28, and a U-shaped draw-in groove 282 offered relatively by each card 28.
Seeing also Fig. 2, this pressure fastener 30 includes the driving plate 32 of four trianglees that parallel interval arranges, and each drives
Dynamic plate 32 includes hypotenuse 322 and one first straight flange 324,1 second straight flange 326.First straight flange 324 of each driving plate 32 with
A pivoting hole 327 is offered in angle between hypotenuse 322, offer at the close hypotenuse 322 of each driving plate 32 one substantially with tiltedly
The chute 328 that limit 322 is parallel.This pressure fastener 30 includes a plate 34, and this connecting plate 34 is straight by the first of four driving plates 32
Limit 324 concatenates.The bottom of this pressure fastener 30 is provided with some pressure card divisions 36 parallel with the second straight flange 326, the end of pressure card division 36
L-shaped.
The interval, bottom of this operating parts 40 arranges four chutes 328 of four projections 42 correspondence pressure fastener 30 respectively.This behaviour
The both sides of workpiece 40 outside projection one stopper 43 respectively, for reinforcement structure, the cross section of stopper 43 takes the shape of the letter U.In this operating parts 40
Between position convex set one handle 44 and one with the elastic pulling part 45 of the flat shape of handle 44, pulling part 45 deviate from the one of handle 44
Side is provided with a card block 452, card block 452 be arranged over some anti-slip veins 454.The middle part of this operating parts 40 rolls downwards
Tiltedly extend and form a vertical stop section 46 in end.Operating parts 40 is in both sides projection one block 47 respectively of stop section 46.
Each pivot 50 is L-shaped shaft-like of a bending, and it includes kelly 52 and a pivot rods 54.Pivot rods 54 is close
Bending part is provided with a salient point 542.
Please with reference to Fig. 3, during assembling, pressure fastener 30 is placed between two tabs 24 of decorating plate 23, makes pressure fastener 30
Pivoting hole 327 respectively align pivot sheet 26 pivoting hole 262, the pivot rods 54 of two pivots 50 is worn respectively outside two tabs 24
Enter the opening of tabs 24, corresponding pivoting hole 327 and pivoting hole 262, so that pressure fastener 30 is articulated in back plate 20.The card of pivot 50
Bar 52 prevents pivot 50 from outwards coming off in being respectively clamped into draw-in groove 282.Salient point 542 on pivot rods 54 prevents pivot rods 54 from excessively wearing
Enter tabs 24.The projection 42 of operating parts 40 is respectively clamped in the corresponding chute 328 of pressure fastener 30.
Seeing also Fig. 4 to Fig. 7, when installing expansion board 100, above carry operating parts 40, the projection 42 of operating parts 40 is in pressure
Slide in the chute 328 of fastener 30, make pressure fastener 30 rotate counterclockwise to sufficient space and expansion board 100 is inserted circuit board
In slot (not shown), the catch 10 of expansion board 100 is placed at fluting 201 and makes the kink 14 of catch 10 be placed in supporting part 21
On.Depression part 40, the projection 42 of operating parts 40 slides in the chute 328 of pressure fastener 30, makes pressure fastener 30 dextrorotation
Turning, pressure card division 36 pressure to pressure fastener 30 is stuck in the bending place of catch 10, because pressure card division 36 is L-shaped, can press respectively and be stuck in catch
The connecting portion 12 of 10 and kink 14.Now, the card block 452 of operating parts 40 blocks shelves on the downside of the retainer 252 of back plate 20, anti-
Only move on operating parts 40.The two stoppers 43 card shelves respectively of operating parts 40 inside the banking stop 242 of back plate 20, the gear of operating parts 40
Stop 46 is inserted inside the limiting section 254 of back plate 20, and two blocks 47 of operating parts 40 are pressed in two convex bridges 27 of back plate 20 respectively.
During dismounting expansion board 100, the pulling part 45 pulling operating parts 40 makes it to the direction away from back plate 20, elasticity occur
Deformation, departs from card shelves to the card block 452 of operating parts 40 and the retainer 252 of back plate 20, above carries operating parts 40, operating parts 40
Projection 42 slides in the chute 328 of pressure fastener 30, makes pressure fastener 30 rotate counterclockwise to sufficient space and is pulled out by expansion board 100
Go out.When pulling pulling part 45, operator can press handle 44 simultaneously, firmly makes pulling part 45 deform to facilitate.
