Description

Plate end high-frequency connector shielding device

Technical field

The present invention relates to a kind of plate end connection device of electronic technology field, particularly a kind of plate end high-frequency connector shielding device.

Background technology

At present, the PCB of high-frequency apparatus generally needs a plurality of PCB to do laminated layout, need to use the plate terminal adapter while between pcb board and pcb board, needing to connect.The conventional panels terminal adapter all is not with shielding construction.In order to prevent between pcb board, between pcb board and plate terminal adapter, and the plate terminal adapter disturbs for the signal of other inter-modules of PCB, need to carry out the shielding between signal.

Shown in Figure 1 is the syndeton between two pcb boards of commonly seeing, and wherein the first pcb board 101 carries out the signal connection by high frequency connectors 104 and the second pcb board 102.In high frequency connectors 104, the magnetic field effect of each terminal after producing by electric current via pcb board 102 can the phase mutual interference, causes output current unstable, and then affects the high high-frequency signal of pcb board 102.And electromagnetic radiation also can produce interference to other assemblies on pcb board, such as, consulting in Fig. 1 shown in arrow,

device

103a and 103b on pcb board are all disturbed by the magnetic field that high frequency connectors produce.

For overcoming the defect of conventional art, industry mainly by welding manner with Copper Foil 105 around high frequency connectors, and weld a copper cash 106 in the PCB earth terminal, thereby realize magnetic field shielding (consulting Fig. 2).But the operations such as the welding of the Copper Foil in this technology and copper wire welding exist the problem of production cost and welding quality keyholed back plate aspect.

Summary of the invention

The object of the present invention is to provide a kind of plate end high-frequency connector shielding device, it can realize between a plurality of pcb boards, between pcb board and high frequency connectors, between high frequency connectors and high frequency connectors and high frequency connect the signal shielding between other components and parts on device and pcb board, thereby overcome deficiency of the prior art.

For achieving the above object, the present invention has adopted following technical scheme:

A kind of plate end high-frequency connector shielding device, comprise high frequency connectors, and it is characterized in that: described screening arrangement also comprises the insulation magnetic core array, and the metal terminal of described high frequency connectors is from described magnetic core array, passing, and with two pcb boards that cooperatively interact, be connected respectively.

Particularly, described high frequency connectors bottom is connected or pegs graft with the first pcb board paster, in its upper end open section, the second pcb board is set.

As a kind of optional execution mode, described high frequency connectors comprise that the upper shed insulator that is arranged at top, the insulation catch that is arranged at bottom and connection run through the metal terminal more than of this insulation catch and this upper shed insulator.

As preferred implementation, between described insulation catch and upper shed insulator, the insulation magnetic core array is set, described metal terminal is from passing this insulation magnetic core array.

As more preferred execution mode, an above through hole is set in described insulation magnetic core array, described metal terminal passes in described through hole.

Postscript, described insulation catch lower end also can connect the insulation keeper, and described metal terminal runs through this insulation keeper.

By above technical scheme, the present invention can realize between two pcb boards by screening arrangement, between pcb board and high frequency connectors, between high frequency connectors and high frequency connectors and high frequency connect the signal shielding between other components and parts on device and pcb board, and it is simple in structure, with low cost, be easy to make, and quality is easy to control.

Embodiment

Below in conjunction with accompanying drawing and a preferred embodiment, technical scheme of the present invention is further described.

Consult Fig. 3-5, this plate end high-frequency connector shielding device 2 comprises high frequency connectors and insulation magnetic core array 202, and the metal terminal 204 of described high frequency connectors is from described magnetic core array, passing, and with two pcb boards 101,102 that cooperatively interact, is connected respectively.

As a kind of optional execution mode, aforementioned high frequency connectors comprise the upper shed plastic insulation 201 that is arranged at top, the plastic retainer sheet 203 that is arranged at bottom and connect the some metal terminals 204 that run through this insulation catch and this upper shed insulator.

Preferably, aforementioned dielectric magnetic core array 202 is arranged between insulation catch 203 and upper shed insulator 201, and the aforementioned metal terminal is from passing this insulation magnetic core array.And described magnetic core array is circumferential enclosure space.

In the aforementioned dielectric magnetic core array, some through holes can be set, described metal terminal passes in described through hole, sees through this design, the noise between each terminal can be done effectively and is covered, and avoids phase mutual interference between each signal.

Postscript, aforementioned plastic retainer sheet 203 lower ends also can connect the insulation keeper, for the position of fixed magnetic core body.The aforementioned metal terminal runs through this insulation keeper 205.
