[embodiment]

In following examples, a plurality of input/output interfaces are integrated, can disposablely be installed on the printed circuit board (PCB), save time, raise the efficiency.

Embodiment one

As shown in Figure 1, be the overall structure stereogram of input/output interface, this input/output interface comprises a serial line interface 100 and a VGA interface 200.Wherein serial line interface 100 and VGA interface 200 parallel interval setting side by side, interface are all towards same direction, and serial line interface 100 and VGA interface 200 are fixed together by supporting structure 300 and form integral structure.

As shown in Figure 2, serial line interface 100 comprise first metal shell 110, as the first plastic cement structure 120 and the serial pin 130 of serial line interface 100 agent structures.Wherein the first plastic cement structure 120 comprises first collets, 122, the first connecting portions 121 and first collets, 122 one-body molded the making of the cuboid of first connecting portion 121 that the front end and first metal shell 110 join and rear end.The width of first collets 122 makes first connecting portion, 121 two ends protrude to Width with respect to first collets 122 less than the width of first connecting portion 121.First connecting portion, 121 two ends projections are provided with first through hole, and the position that first metal shell 110 is corresponding with first through hole of first connecting portion 121 is provided with first connecting hole 111 (as shown in Figure 4).Serial pin 130 separates each other and is distributed in the plastic cement structure 120, one end stretches out the space that is in 110 encirclements of first metal shell from first connecting portion, 121 1 sides at first metal shell, 110 places, and the other end stretches out the back from first collets, 122 1 sides and extends insertion VGA interface 200.

VGA interface 200 comprises second metal shell 210, as the second plastic cement structure 220 and the VGA pin 230 of VGA interface 200 agent structures.The second plastic cement structure 220 comprise second connecting portion 221 that the front end and second metal shell 210 join, rear end cuboid second collets 222 and be housed in intercalation part 223 (as shown in Figure 4) in second metal shell 210.Intercalation part 223, second connecting portion 221 and second collets 222 connect and one-body molded making successively.The width of the intercalation part 223 and second collets 222 makes second connecting portion, 221 two ends protrude to Width with respect to the intercalation part 223 and second collets 222 less than the width of second connecting portion 221.Second connecting portion, 221 two ends projections are provided with second through hole, and the position that second metal shell 210 is corresponding with second through hole of second connecting portion 221 is provided with second connecting hole 211 (as shown in Figure 4).VGA pin 230 separates each other and is distributed in second collets 222, and an end is arranged in the intercalation part 223 that second metal shell 210 surrounds and the interface holes 224 by intercalation part 223 exposes, and an end stretches out from second collets 222.Serial pin 130 inserts second collets 222 from second collets, 222 1 sides, and passes from opposite side, constitutes the grafting pin of input/output interface with VGA pin 230.

As shown in Figure 3, because the position of serial line interface 100 and VGA interface 200 is comparatively close, the signal between them may influence each other, in order to suppress this influence, the outer wrap of second collets 222 layer of metal screen 600.

Supporting structure 300 comprises two identical members, is individually fixed in the both sides of input/output interface.Described member comprises two mutually perpendicular first limits 310 and second limit 320.All fixedly connected with VGA interface 200 with serial line interface 100 in first limit 310, second limit 320 and serial line interface 100 and VGA interface 200 towards parallel.Wherein on first limit 310 first screwed hole and second screwed hole are arranged, screw 400 is fixedly connected sequentially first metal shell 110, first connecting portion 121 and described first limit 310 by first connecting hole 111, first through hole and first screwed hole, screw 400 is fixedly connected sequentially second metal shell 210, second connecting portion 221 and described first limit 310 by second connecting hole 211, second through hole and second screwed hole, thereby serial line interface 100 and VGA interface 200 is formed to be arranged in parallel up and down, interface is towards being fixed as one structure consistent, that the grafting pin is concentrated.

As shown in Figure 2, in order to hold more pin, second collets, 222 volume ratios, first insulation certainly 112 volume wants big, and serial pin 130 also needs to do suitable outwardly-bent insertion second collets 222 that extend then downwards.

As shown in Figure 4, on second limit 320 of supporting structure 300 two holes 321 are arranged, two of fixedly pin 500 that the centre is provided with opening wore described hole 321 and fixedlyed connected with second limit 320.When being fixed on input/output interface on the printed circuit board (PCB), fixedly pin 500 via hole that passes printed circuit board (PCB) is fixed on input/output interface on the printed circuit board (PCB), and the fixedly pin 500 that the centre is provided with opening is out of shape when passing via hole, is easy to assembling and fixing.

Embodiment two

Metal screen layer 600 also can be wrapped in all coated metal screens 600 of outside or first collets 122 of first collets 122 and second collets 222.

The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
