It is connected to cooperate with the first support portion 112 of the first shield 110 and the second support portion 113, it can be to differential signal
It wraps up being formed, increases shield effectiveness, to further reduce the crosstalk between differential pair.In other optional embodiments
In, above-mentioned connector 122 can only include one group, for example, being only arranged at the first side 1211 or the of the second support plate 121
Two sides 1212.
In optional embodiment of the present invention, each group of connector 122 includes at least one baffle 1221.
When secondary shielding body 120 is connected to the first shield 110, the end of each baffle 1221 all extends to groove
In 111.
In optional embodiment of the present invention, each group of above-mentioned connector 122 includes two baffles 1221.Specifically
Ground, in the first side 1211 of the second support plate 121, there are two baffles 1221 for setting, and two intervals of baffle 1221 are arranged.Equally
Ground, in the first side 1211 of the second support plate 121, there are two baffles 1221 for setting, and two intervals of baffle 1221 are arranged.Pass through
Two baffles 1221 are set simultaneously in the two sides of the second support plate 121, for extending in the first shield 110, further
The shield effectiveness of entire shielding part 100 is enhanced, the crosstalk between differential pair is reduced.
Further, the distance between above-mentioned two groups of baffles 1221 that 121 two sides of the second support plate are arranged in is less than first
The distance between first support portion 112 and the second support portion 113 of shield 110.In other words, when secondary shielding body 120 connects
When being connected to the first shield 110, two groups of baffles 1221 are between the first support portion 112 and the second support portion 113.
Still optionally further, referring to Fig. 3, one group of connector is also equipped in the third side 1213 of the second support plate 121
122.That is the second support plate 121 is provided with three groups of connectors 122 altogether, and two groups of connectors 122 are separately positioned on the second support plate 121
The first opposite side 1211 and second side 1212, third group connector 122 are arranged in third side 1213, that is, are located at the first side 1211
Between second side 1212.By simultaneously be arranged three groups of connectors 122, can further improve entire shielding part 100 for
The shield effectiveness of signal terminal reduces the crosstalk between differential pair.
Further, the connector 122 at third side 1213 is set, also can choose including at least one baffle
1221.It should be noted that the shape size of baffle 1221 does not limit, it can be according to practical situation to the size of baffle
Diminution, amplification or adjustment appropriate are carried out, to select that an appropriate number of baffle is arranged.
Further, incorporated by reference to Fig. 1 and Fig. 5, the first support portion 112 and the second support portion 113 are arranged in two groups of baffles
1221 outside can preferably wrap up two groups of baffles 1221.At this point, can be seen that from the end face direction of entire shielding part 100
First shield 110 and secondary shielding body 120 form respectively the package shielding construction of U-shaped, and the formation of the first shield 110
U-shaped the package shielding construction U-shaped that is located at the formation of secondary shielding body 120 package shielding construction inside, to reach double
Shield effectiveness again.Therefore, the crosstalk between differential pair can be greatly reduced.
In other optional embodiments of the invention, the shape of two groups of connectors 122 above-mentioned, which also can choose, to be set as
Other shapes, such as round, ellipse or other irregular shapes.
