Description
Technical field
The utility model relates to the backplane technology of communication equipment, particularly a kind of double-sided inserted backplane.
Background technology
At present, along with the requirement that communication system improves integrated level, adopt the double-sided inserted backplane number of slots order that directly doubles to become the trend of backplane technology.The multiplication of number of slots purpose makes the configuration granularity of system business on veneer better carry out balance, directly brings the flexibility and the reliability of design, and the integrated possibility that provides of fecund product also is provided simultaneously.
Referring to Fig. 1, Fig. 1 is the connection diagram of prior art double-sided inserted backplane and veneer.Wherein, preceding veneer 100 is by the pronotum connector 111 of plug 101 insertion double-sided inserted backplanes 110, and back veneer 120 inserts double-sided inserted backplanes 110 postnotum connectors 112 by plug 121.As shown in Figure 1, before veneer 100 and its correspondence back veneer 120 front and back over against, and pronotum connector 111 and postnotum connector 112 be not on same level height, pronotum connector 111 is positioned at the upside of double-sided inserted backplane 110 fronts, and postnotum connector 112 is positioned at the downside of double-sided inserted backplane 110 back; Accordingly, the plug 121 of the plug 101 of preceding veneer 100 and back veneer 120 also not on same level height, promptly staggers up and down.From the front, the upper right side of veneer 100 before the plug 101 of preceding veneer 100 is positioned at, the plug 121 of back veneer 120 is positioned at the lower right of back veneer 120, and back veneer 120 is from the back side, so plug 121 is positioned at the lower left of back veneer 120 among Fig. 1.
Among Fig. 1, the structure of preceding veneer 100 and back veneer 120 is different, though the definition of the interface contact pin of pronotum connector 111 and postnotum connector 112 can be identical, and their upper-lower position difference, so preceding veneer 100 and back veneer 120 are general before and after can not be on double-sided inserted backplane.
As seen, this double-sided inserted backplane has a shortcoming that is difficult to overcome: the veneer of forward and backward groove position can not be general, and it is integrated back-to-back to be similar to two frames in essence.
At above-mentioned shortcoming, occurred adopting special-purpose back panel connector to realize the general design philosophy of front and back groove position veneer.
Referring to Fig. 2, Fig. 2 is the general double-sided inserted backplane of prior art and the design diagram of veneer.Wherein, preceding veneer 200 is by the pronotum connector 211 of plug 201 insertion double-sided inserted backplanes 210, and back veneer 220 inserts the postnotum connector 212 of double-sided inserted backplanes 210 by plug 221.Pronotum connector 211 and postnotum connector 212 all comprise power interface and signaling interface, on same level height, the interface contact pin definition of pronotum connector 211 and postnotum connector 212 is identical, so preceding veneer 200 and back veneer 220 can be general on backboard.Back veneer 220 so plug 221 is positioned at the left side of back veneer 120, sees in fact that back veneer 220 is identical with preceding veneer 200 from the back side among Fig. 2 from the front.
Wherein, pronotum connector 211 on the double-sided inserted backplane 210, postnotum connector 212 adopt identical special-purpose back panel connector, and front and back, complete matching up and down, the contact pin crimping degree of depth of the contact pin of pronotum connector 211 and postnotum connector 212 must less than or near equaling half of back plate thickness, mutually insulated.
Above-mentioned this double-sided inserted backplane requires quite highly to the circuit board of double-sided inserted backplane, thickness error requires very little, otherwise can not guarantee the special-purpose back panel connector crimping degree of depth less than or near a half-sum mutually insulated that equals back plate thickness.Because the specificity of this back panel connector, and backboard PCB design, production, backboard processing of adopting this connector etc. all have specific (special) requirements, directly bring difficulty expensive and that the big grade of engineering difficulty is difficult to overcome, so this double-sided inserted backplane only is in the design philosophy stage at present, can't in actual production, be achieved, can't be used widely.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of double-sided inserted backplane, and veneer is general before and after realizing, reduces the design and the production difficulty of double-sided inserted backplane, reduces the design cost of veneer simultaneously.
For achieving the above object, the technical solution of the utility model specifically is achieved in that
A kind of double-sided inserted backplane, the one side of this double-sided inserted backplane is provided with one or more pronotum connectors, the another side of this double-sided inserted backplane is provided with one or more postnotum connectors, and pronotum connector and postnotum connector stagger up and down, and described pronotum connector distance of veneer height mid point to the double-sided inserted backplane equates with the distance of postnotum connector to veneer height mid point; Described pronotum connector and postnotum connector are same size, the contact pin definition back panel connector of reversed in order and left and right sides reversed in order up and down.
Wherein, each forward and backward back panel connector all can comprise power interface connector, signaling interface connector and backboard alignment connector.
Described power interface connector and signaling interface connector all can be common back panel connector, for example common ZD connector.
Described backboard alignment connector can be guiding/anti-error pin; Guiding/anti-error pin can be separately positioned on the upper/lower terminal of forward and backward back panel connector.
Described guiding/anti-error pin can lead for taper/guiding/anti-error pin of anti-error pin or other shapes.
By the technical solution of the utility model as seen, this double-sided inserted backplane of the present utility model, pronotum connector and postnotum connector stagger up and down, pronotum connector distance of veneer height mid point to the double-sided inserted backplane equates with the distance of postnotum connector to veneer height mid point, and the definition of front and back back panel connector contact pin is reversed in order, left and right sides reversed in order up and down, like this, as long as veneer Rotate 180 degree just can be inserted on the another side of double-sided inserted backplane.Therefore, the utility model can adopt general connector to realize that very easily forward and backward veneer is general, all do not have specific (special) requirements for backboard PCB design, production, backboard processing etc., reduced the design and the production difficulty of double-sided inserted backplane, reduce the design cost of veneer simultaneously.
