Embodiment
Shown in Fig. 2,3, when mainboard 2 is instead inserted along guide rail 5, the position of the position of motherboard connector 22 during with normal grafting is just opposite, then causes motherboard connector 22 not corresponding with back panel connector 31, during rigid grafting, can cause the damage of motherboard connector 22 and back panel connector 31.Therefore take place for fear of this kind situation; be provided with counnter attack in backboard 3 ends in back panel connector 31 outsides and insert protective cradle 1; counnter attack is inserted protective cradle 1 and is adopted the corrosion resistant plate of 1.5mm thickness to make; the preferred SUS301 that adopts; 1.5mm the corrosion resistant plate SUS301 intensity of thickness is high especially; can bear high-intensity impact, and stainless steel also has good corrosion resistance, good die-cut Bending Processing performance.As shown in Figure 1, when mainboard 2 was just being inserted, motherboard connector 22 was pegged graft with back panel connector 31; Shown in Fig. 2,3; during mainboard 2 anti-inserting, because the grafting end face that the height of protective cradle 1 exceeds back panel connector 31 is inserted in counnter attack, then mainboard 2 at first contacts counnter attack and inserts protective cradle 1; mainboard 2 roof pressures are inserted on the protective cradle 1 in counnter attack, make motherboard connector 22 not contact back panel connector 31.The grafting end face of described back panel connector 31, the grafting end face of motherboard connector 22 are meant the two corresponding face of pegging graft mutually.When instead inserting in order to ensure mainboard, motherboard connector 22 does not contact with back panel connector 31, and then in the present embodiment, counnter attack is inserted protective cradle 1 and is provided with one in 3 two ends of backboard respectively.The end of backboard 3 is meant the outside, back panel connector 31 vertical two ends, i.e. two ends up and down shown in Fig. 1.
As shown in Figure 1, described motherboard connector 22 end arranged outside have keeper 21, be respectively arranged with guide-localization bar 32 on the corresponding backboard 3, the outside, motherboard connector 22 ends is meant the outside, motherboard connector 22 vertical two ends, the i.e. outside, two ends up and down shown in Fig. 1.For motherboard connector 22 is smooth and easy with back panel connector 31 grafting, present embodiment all is provided with keeper 21 in the outside, motherboard connector 22 both ends, and the two ends of every group of back panel connector 31 all are respectively equipped with guide-localization bar 32 on the backboard 3.And except at mainboard 2 and backboard 3 ends keeper 21 and guide-localization bar 32 being set, correspondence is provided with keeper 21 and guide-localization bar 32 respectively in every group of motherboard connector 22 and back panel connector 31.When mainboard 2 was just being inserted, keeper 21 cooperations were plugged on the guide-localization bar 32; Shown in Fig. 2,3, during mainboard 2 anti-inserting, keeper 21 roof pressures are inserted on the protective cradle 1 in counnter attack, make motherboard connector 22 not contact back panel connector 31.As Fig. 1, shown in 3, keeper 21 is provided with through hole, keeper 21 is pegged graft by through hole and guide-localization bar 32, and the length of guide-localization bar 32 will be higher than the height of back panel connector 31, therefore, in motherboard connector 22 with before back panel connector 31 contacts, guide-localization bar 32 front ends just insert in the through hole of keeper 21, mainboard 2 is pegged graft with backboard 3 under the guiding of keeper 21 and guide-localization bar 32, avoided also just having avoided the damage that not corresponding grafting causes between motherboard connector 22 and the back panel connector 31 owing to mainboard 2 departs from the problem that causes motherboard connector 22 not corresponding with back panel connector 31.
As shown in Figure 1; described counnter attack is inserted protective cradle 1 and is included in the rack body 11 that backboard 3 both ends are provided with; described rack body 11 is a plank frame; plate face perpendicular to backboard 3 is provided with; described backboard 3 two ends are provided with and are used for backboard 3 is fixed on central post 4 in the cabinet; described central post 4 is arranged on backboard 3 two ends and parallel with backboard 3 end faces, and backboard 3 two ends are meant two ends up and down as shown in Figure 1.Described rack body 11 by screw retention on central post 4.
Be extended with counnter attack in the space between the adjacent in twos back panel connector 31 in described rack body 11 toward back plate 3 ends and insert flanging 12, described counnter attack is inserted flanging 12 and is exceeded back panel connector 31 grafting end faces, and keeper 21 roof pressures of mainboard 2 are inserted on the flanging 12 and motherboard connector 22 does not contact with back panel connector 31 in counnter attack when making mainboard 2 anti-inserting.As a preferred embodiment, the position in the space of flanging 12 between adjacent in twos back panel connector 31 is inserted in counnter attack, when satisfying mainboard 2 and just inserting, described counnter attack is inserted flanging 12 between mainboard keeper 21 and adjacent another mainboard 2, does not influence the just slotting of mainboard 2.
Described rack body 11 is the stripe board of corresponding all back panel connector 31 ends, rack body 11 end faces exceed the grafting end face of back panel connector 31, described counnter attack is inserted flanging 12 and is disposed on rack body 11 end faces, each counnter attack is inserted flanging 12 1 ends and is fixed on rack body 11 end faces, and the other end extends in the gap between the adjacent in twos back panel connector 31.
The another kind of embodiment of rack body 11: rack body 11 is provided with a plurality of at interval, each rack body 11 is corresponding one or more back panel connectors 31 respectively, all be fixed with counnter attack on each rack body 11 end face and insert flanging 12, each counnter attack is inserted flanging 12 1 ends and is fixed on rack body 11 end faces, and the other end extends in the gap between the adjacent in twos back panel connector 31.
