Abstract
The utility model relates to the technical field of electronic connectors for signal transmission and especially relates to a connection device for signal transmission. The connection device comprises a plate-end PCB, a component module plastic part and a plate-end connector, wherein component modules are arranged in the component module plastic part, the plate-end connector includes a plate-end plastic part and plate-end signal terminals corresponding to the component modules, each component module is provided with a plug-in piece and an assembly arranged outside the plug-in piece, each assembly is composed of a metal/conductive plastic shielding sheet and a connecting piece fixed at the lower end of the metal/conductive plastic shielding sheet, the plate-end connector further includes plate-end metal shielding sheets, and the plate-end signal terminals and the plate-end metal shielding sheets are placed in a staggered mode. The connection device for signal transmission is simple in structure, mutual interference among signals can be greatly reduced due to the additional arrangement of the plate-end metal shielding sheets as well as the metal/conductive plastic shielding sheets on the component modules, signals can be transmitted faster and more stably, and the high-frequency performance of the whole system can be improved.
Description
Technical field
The utility model relates to the technical field for the electric power connector of signal transmission, especially a kind of jockey for the signal transmission.
Background technology
The High speed rear panel connector is mainly used in the inner mainboard of connection server and subcard, subcard and subcard, to reach the purpose of power supply and signal transmission, the High speed rear panel connector, the jockey that namely is used for the signal transmission in the current industry, is used for the jockey of signal transmission in use, the problem of phase mutual interference is serious between the signal, has so just reduced widely the stability of whole system and the operating efficiency of system.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of jockey that is used for the signal transmission for promoting signaling rate and raising stable signal transmission is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of jockey for the signal transmission, comprise plate end PCB, component module plastic parts and plate terminal adapter, be provided with component module in the component module plastic parts, the plate terminal adapter comprise plate end plastic parts and with the corresponding plate end signal of component module terminal, described component module has plug-in unit and is fixedly mounted on the sub-assembly in the plug-in unit outside, sub-assembly is comprised of metal/conductive plastic shielding sheet and the connector that is fixed on metal/conductive plastic shielding sheet lower end, described plate terminal adapter also comprises plate end metallic shield sheet, and plate end signal terminal and plate end metallic shield sheet are staggeredly placed.
Be provided with at least four outwards shell fragments of projection on the described plate end metallic shield sheet, plate end signal terminal and plate end metallic shield sheet carry out the signal transmission by shell fragment.
What described shell fragment was inhomogeneous is distributed on the plate end metallic shield sheet.
The beneficial effects of the utility model are: the utility model is simple in structure, the phase mutual interference of the metal that increases on the component module/conductive plastic shielding sheet between can greatly less signal, can make faster, the more stable transmission of signal, improve the high frequency performance of whole system.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.

Among the figure: 1. component module plastic parts, 2. plate terminal adapter, 21. plate end plastic parts, 22. plate end signal terminals, 23. plate end metallic shield sheets, 3. component module, 31. plug-in units, 32. sub-assemblies, 321. metals/conductive plastic shielding sheet.
Embodiment
With preferred embodiment the utility model is further described by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Such as Fig. 1, Fig. 2, Fig. 3 and a kind of jockey for the signal transmission shown in Figure 4 comprise plate end PCB, component module plastic parts 1 and plate terminal adapter 2, be provided with component module 3 in the component module plastic parts 1, plate terminal adapter 2 comprise plate end plastic parts 21 and with component module 3 corresponding plate end signal terminals 22, component module 3 has plug-in unit 31 and is fixedly mounted on the sub-assembly 32 in plug-in unit 31 outsides, sub-assembly 32 is comprised of metal/conductive plastic shielding sheet 321 and the connector that is fixed on metal/conductive plastic shielding sheet 321 lower ends, described plate terminal adapter 2 also comprises plate end metallic shield sheet 23, and plate end signal terminal 22 is staggeredly placed with plate end metallic shield sheet 23.
Be provided with at least four outwards shell fragments of projection at plate end metallic shield sheet 23, what shell fragment was inhomogeneous is distributed on the plate end metallic shield sheet 23, and plate end signal terminal 22 carries out the signal transmission with plate end metallic shield sheet 23 by shell fragment.
The utility model has increased plate end metallic shield sheet 23 and has increased metal/conductive plastic shielding sheet 321 at the sub-assembly 32 of component module 3, plate end metallic shield sheet 23 is interconnected with metal/conductive plastic shielding sheet 321, plate end signal terminal 22 can be enclosed in signal in the shielding sheet with the component module terminal, the phase mutual interference between the greatly less signal.
The effect that plate end metallic shield sheet 23 can shell fragment longitudinally in the utility model is set, and shell fragment divided, be surrounded with horizontal plate end metallic shield sheet 23 shell fragment with the centre so again, thereby make the signal can faster more stable transmission, and improved the high frequency performance of product.
Differential signal between metal on each module/321 pairs of modules of conductive plastic shielding sheet plays shielding action simultaneously, reduces crosstalking between the differential signal between the module.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present utility model and is implemented; can not limit protection range of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in the protection range of the present utility model.
