In order to solve the above technical problems, the invention adopts the following technical scheme:
A kind of metal shielding board for high-speed differential signal connector, including barricade main body, the one of above-mentioned barricade main body
It is arranged at intervals with more than two bulge-structures on side, and is provided with salient point above above-mentioned bulge-structure.
Preferably, when above-mentioned metal shielding board is mounted on above-mentioned male end signal transmission module or female end signal transmission module
When upper, above-mentioned bulge-structure is located between male end signal transmission module or the adjacent Difference signal pair of female end signal transmission module.
Preferably, the one end of above-mentioned barricade main body be provided with for female end signal transmission module or male end signal
The bending protrusion that transmission module is clamped, the protrusion direction phase of the overbending direction and above-mentioned bulge-structure of above-mentioned bending protrusion
Instead.
Preferably, one end opposite with bending protrusion in above-mentioned barricade main body is arranged at intervals with for solid with pedestal
Determine, the protruding teeth of conducting, is provided in a side of above-mentioned barricade main body for " L " type latch fixed with pedestal.
Compared with prior art, the beneficial effects of the present invention are:
It is multiple after metal shielding board is fixed with male end signal transmission module or female end signal transmission module in the present invention
Male end signal transmission module or female end signal transmission module will do it laid out in parallel, can make metal shielding board and adjacent male end
Multiple spot connection is realized between signal transmission module or the shielding shell of female end signal transmission module, to shorten return flow path.
Bulge-structure in the present invention can form ground hole around the telltale hole in signal transmission module, and be located at letter
Number differential pair between any two, to reduce the crosstalk between signal.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the side view of certain one side of the invention.
Fig. 3 is the overall structure diagram after metal screen and signal transmission module installation of the invention.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Referring to Fig. 1,2, for one embodiment of the present of invention, a kind of metallic shield for high-speed differential signal connector
Plate, including barricade main body 200 are arranged at intervals with more than two bulge-structures in a side of above-mentioned barricade main body 200
206, and the top of above-mentioned bulge-structure 206 is provided with salient point 207, and which is the one of barricade main body 200
It is the protrusion for amplifying formation upwards on the side, salient point is used for and adjacent male end signal transmission module or female end on side
Signal transmission module is contacted.In the present embodiment, when metal shielding board and male end signal transmission module or female end signal pass
After defeated module is fixed, multiple male end signal transmission modules or female end signal transmission module will do it laid out in parallel, protrusion knot
Structure 206 can make between metal shielding board and adjacent male end signal transmission module or the shielding shell of female end signal transmission module
Multiple spot connection is realized, to shorten return flow path.
Further, for one embodiment of the present of invention, on the basis of the above embodiments, when above-mentioned metal shielding board
When being mounted on above-mentioned male end signal transmission module or female end signal transmission module, above-mentioned bulge-structure 206 is located at male end signal
Between transmission module or the adjacent Difference signal pair of female end signal transmission module.As shown in figure 3, the protrusion knot on metal shielding board
When structure is mounted on male end signal transmission module or female end signal transmission module, which will be in signal differential to 301
Between formed ground hole 208, therefore bulge-structure should be located at male end signal transmission module or female end signal transmission module it is adjacent
Between Difference signal pair, to reduce the crosstalk between signal.
Further, for one embodiment of the present of invention, on the basis of the above embodiments, above-mentioned barricade main body
200 one end is provided with the bending protrusion for being clamped with female end signal transmission module or male end signal transmission module
203, the overbending direction of above-mentioned bending protrusion 203 is opposite with the protrusion direction of above-mentioned bulge-structure 206.In the present embodiment, setting
Bending protrusion is conducive to for barricade main body and male end signal transmission module or female end signal transmission module being fixed, due to bridge
Girder construction is to carry out multiple spot with adjacent female end signal transmission module or male end signal transmission module to be connected to, therefore the bending protrusion
Overbending direction be opposite with the protrusion direction of bulge-structure.
Further, for one embodiment of the present of invention, on the basis of the above embodiments, above-mentioned barricade main body
