Embodiment
Your juror can further understanding and understanding be arranged for ease of, for the embodiment conjunction with figs., to be described in detail as follows now technical problem, feature and the effect of shape of the present utility model, structure and device:
What the utility model proposes is a kind of in order to prevent that electromagnetism from involving the member of reinforcement printed circuit board (PCB), it mainly is installed on the printed circuit board (PCB) 10, see also shown in Figure 1, one end of this printed circuit board (PCB) 10 is provided with a panel 11, the then protruding dew of the other end has connector (connector) (not shown) of a plurality of predetermined spaces of being separated by, and this connector is in order to connect each node in each set on this printed circuit board (PCB) 10 parts (not shown) or the system.
Wherein in the upper side edge of this printed circuit board (PCB) 10 and lower side between this panel 11 and its other end connector, respectively be provided with a long and narrow iron plate 20 respectively, this long and narrow iron plate 20 is a L shaped section body, the one side of this long and narrow iron plate 20 is an installment surface 21, its upper side edge and lower side that acts on this printed circuit board (PCB) 10 connects, and this long and narrow iron plate 20 then is a reinforcement face 22 at the another side that joins with these installment surface 21 orthogonals, it can be used to these long and narrow iron plate 20 intensity of reinforcement, simultaneously, setting by this reinforcement face 22 is this printed circuit board (PCB) 10 of reinforcement relatively, make it remain on the plane, do not lift up the phenomenon generation of bending distortion and do not have.
In this embodiment, the installment surface 21 of this long and narrow iron plate 20 is fixed on the upper side edge and lower side of this printed circuit board (PCB) 10 by a blind rivet 23 modes, but the utility model is not limited thereto when reality is implemented, and it can be designed to alternate manner and fix.
By above-described member, can know and learn, see also Fig. 2, shown in 3, when panel 11 with these printed circuit board (PCB) 10 1 ends, when the set guide groove of metal up and down 31 pushes in a device 30, long and narrow iron plate 20 on these printed circuit board (PCB) 10 upper side edges and the lower side, just can distinguish directly with should about metal guide groove 31 contact, make it when slipping into this metal guide groove 31, can be by the each other metallic character of this long and narrow iron plate 20 with metal guide groove 31, and more light, smooth and easy, simultaneously, by this long and narrow iron plate 20 and contacting of metal guide groove 31 up and down, more can reach the electromagnetic interference (EMI) effect that prevents that this device 30 from being produced when operating.In addition, because of this long and narrow iron plate 20 is arranged on the upper side edge and the lower side of this printed circuit board (PCB) 10, can prevent effectively that lifting up of this printed circuit board (PCB) 10 from bending is out of shape, and makes it remain on the straight horizontal plane, when making it in inserting this device 30, can obtain a preferable guiding face and a holding power.
Otherwise, when taking out these printed circuit board (PCB)s 10, equally can be by the guiding booster action of these long and narrow iron plates 20, and can be under no deflection, the state that rocks, the application of force makes these printed circuit board (PCB)s 10 take out smoothly along the guide groove of metal up and down 31 of this device 30.
In this embodiment, aforesaid this device 30 can be electronic products such as a server, networking interchanger.
Therefore, greatest feature of the present utility model, be to have overcome the traditional printing circuit board because of occupying suitable area, cause lifting up easily bending and be out of shape, the softer phenomenon of losing easily of substrate, and the structure (as: contact flat spring) that prevents electromagnetic interference must additionally be set on the guide groove of metal up and down 31 of this device 30 and then increase the shortcoming of the phenomenon of cost, so this long and narrow iron plate 20 is located on the side up and down and side of printed circuit board (PCB) 10, use the intensity of this printed circuit board (PCB) 10 of reinforcement, make it remain on the straight horizontal plane, do not bend distortion and can not produce to lift up, so, can effectively reach the electromagnetic interference that is produced when preventing these device 30 runnings, and then realized preventing that this printed circuit board (PCB) 10 from lifting up bends distortion, cross soft shortcoming, simultaneously, solve the problem of electromagnetic interference in the lump, because the utility model not only possesses more traditional advantage simple in structure, and on cost, also can significantly reduce, simultaneously, can have reinforcement again concurrently and prevent electromagnetic interference, therefore, the utility model is one to meet the design of hommization in fact.
The above, only be the specific embodiment of the utility model the best, only structural feature of the present utility model is not limited thereto, and allly anyly is familiar with this skill person in the utility model field, can think easily and variation or modification, should all covered in the claim of this case.
