In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with drawings and embodiments.
Reference structural representation of the present utility model shown in Figure 4:
First circuit board 401 links to each other by a pair of first connector J11 with auxiliary connecting plate 402, and second circuit board 403 links to each other by a pair of second connector J12 with auxiliary connecting plate 402.
First connector is connected in the front of assisting connecting plate by signal pin, and second connector is connected in the back side of auxiliary connecting plate by signal pin.Wherein, the first connector J11 and the second connector J12 on the auxiliary connecting plate are overlapping on riding position top, the signal pin of the first connector J11 is pulled out at lap, first circuit board 401 is connected with auxiliary connecting plate 402 signals by the remaining signal pin of the first connector J11, and second circuit board 403 is connected with auxiliary connecting plate 402 signals by the signal pin of second connector.
Auxiliary connecting plate can use backboard, can certainly use supporting plate.
First connector and second connector are the pluging connector that has signal pin, and its type, size can be identical, also can be different.
Such as, can be in the following various connector one or more:
The straight public connector of 2mmHM, the curved public connector of 2mmHM, the straight public connector of PCMCIA, the curved public connector of PCMCIA.
Certainly, in actual applications, can select one for use, also can use a plurality of.
As an application example of the present utility model, Fig. 5 shows the structural representation of the jockey of a kind of mainboard and SIC card:
In this embodiment, adopt the mode of backboard to connect mainboard and SIC card,, and make mainboard and SIC card realize that signal is connected with saving device interior space.
The end that mainboard S1 is connected with backboard S2 is crimped with curved female connectors (band shielding needle) J5 ' of 8 * 25 2mmHM, links to each other with 8 * 25 the straight public connector of 2mmHM (band shielding needle) J5 in backboard front; The end that SIC card S3 links to each other with backboard S2 is welded with PCMCIA connector J3 ', links to each other with the straight public connector J3 of PCMCIA at the backboard S2 back side; The end that SIC card S4 links to each other with backboard S2 is welded with PCMCIA connector J1 ', links to each other with the straight public connector J1 of PCMCIA at the backboard S2 back side.
The signal pin that conflicts with the straight public connector of PCMCIA position on the 2mmHM connector is pulled out, and the position of two straight public connectors of PCMCIA and 2mmHM connector are pulled out the location overlap of signal pin.
Structural design mode when the position conflict being arranged for different connector in clearer description the utility model, Fig. 6 shows the front view and the rearview of backboard:
Wherein, the straight public connector J5 of 2mmHM, J6, J7 that connect mainboard and backboard are by the vertical front that is crimped on backboard of signal pin, its base is concordant substantially with the base of backboard, so that behind the straight public connector of mainboard insertion 2mmHM, mainboard bottom surface and backboard base substantially on same horizontal plane, thereby meet design requirement.
The straight public connector J1 of PCMCIA, J2, J3, the J4 that connect SIC card and backboard are welded in the back side of backboard by signal pin.J1, J2 be near the bottom of backboard, and J3, J4 be near the top of backboard, and with the side of the straight public connector of 2mmHM one predetermined space is arranged in vertical direction respectively.
In order to reduce the requirement to the backboard height, the straight public connector J1 of PCMCIA and the straight public connector J5 of 2mmHM, J6 are overlapped, and the straight public connector J2 of PCMCIA and the straight public connector J7 of 2mmHM, J6 are overlapped.At lap, the signal pin of the straight public connector of 2mmHM is pulled out.Like this, though that the position of different connector on backboard has is overlapping, can not cause signal conflict.Mainboard is connected with backboard S2 signal by the remaining signal pin of the straight public connector of 2mmHM, and the signal pin that the SIC cartoon is crossed the straight public connector of PCMCIA is connected with backboard S2 signal.
According to the actual specification requirement of equipment, can make the base of the straight public connector of PCMCIA parallel, and keep certain interval with the base of the straight public connector of 2mmHM.Like this, after the SIC card inserted the straight public connector of PCMCIA, its base and backboard base kept certain intervals.Certainly, also can make the base of the base of the straight public connector J1 of PCMCIA, J2 and the straight public connector of 2mmHM substantially on same horizontal plane.Like this, after the SIC card inserted the straight public connector of PCMCIA, its base and backboard base were maintained at the same horizontal plane substantially.
The connector of connecting interface card and backboard (the straight public connector of PCMCIA) can be set according to actual needs with the particular location of the connector that is connected mainboard and backboard (the straight public connector of 2mmHM) on backboard.
Usually, the plug of mainboard and interface card for convenience, PCMCIA connector and 2mmHM connector on the backboard all adopt straight public connector.Like this, the curved female connectors of corresponding 2mmHM welding the corresponding straight female connectors of PCMCIA on the interface card, can realize that mainboard, SIC card are connected with backboard in crimping on the mainboard, and makes mainboard keep parallel placement up and down with the SIC card.
Certainly, when specific product designs, can select various connector according to actual needs for use.PCMCIA connector and 2mmHM connector on the backboard also can use straight female connectors.Like this, the curved public connector of corresponding 2mmHM welding the corresponding straight public connector of PCMCIA on the interface card, can realize that equally also mainboard, interface card are connected with backboard in crimping on the mainboard.
Such as, in structure shown in Figure 6, placed the straight public connector of PCMCIA of three 8 * 25 straight public 2mmHM connector, four 62mm * 9mm.Four SIC card are provided.Can connect ethernet network interface card, wan interface cards, voice interface card etc.
In order to make present technique field personnel understand the utility model better, Fig. 7 shows the end view of the jockey of above-mentioned the utility model mainboard and interface card:
From the side of backboard S2,2mmHM connector and PCMCIA connector lay respectively at the both sides of backboard, can only see 2mmHM connector J5 and PCMCIA connector J1, J3 in the drawings.2mmHM connector J6, J7 overlap with J5, and PCMCIA connector J2 overlaps with J1, and PCMCIA connector J4 overlaps with J3.
As can be seen from the figure, PCMCIA connector J1 and the position of 2mmHM connector J5 on backboard overlap.At lap, the signal pin of 2mmHM connector is pulled out.Like this, though that the position of different connector on backboard has is overlapping, can not cause signal conflict.Mainboard is connected with backboard S2 signal by the remaining signal pin of 2mmHM connector, and interface card is connected with backboard S2 signal by the signal pin of PCMCIA connector.
Fig. 8 shows the contact pin schematic diagram of three 2mmHM connectors.
Wherein, the 2mmHM connector J5 that circle is represented, the signal pin of J6, J7 are pulled out, and the remaining signal pin that round dot is represented is realized the interconnection of backboard and mainboard.
Though only mentioned PCMCIA connector and 2mmHM connector in the foregoing description, but the utility model is not limited to this two kinds of connectors, so long as the connector of plug-in type, and on the position, having conflict, those skilled in the art can make the various modifications that are equal in scope of the present utility model.
Though described the utility model by embodiment, those of ordinary skills know, the utility model has many distortion and variation and does not break away from spirit of the present utility model, wishes that appended claim comprises these distortion and variation and do not break away from spirit of the present utility model.
