2. The gap between the two contact sections in one differential signal terminal pair is larger than the gap between the two elastic sections, so that the inductance distance and the capacitance distance in the differential signal terminal pair are reduced, mutual inductance and mutual capacitance are increased, the inductance and capacitance expressed externally integrally are reduced, and tight coupling is increased, so that crosstalk is reduced. Because the gap between two elastic segments in one differential signal terminal pair, namely the second gap, is smaller, the insulating body is not easy to form the partition at the second gap, and the insulating attachment layer part is positioned at the second gap and can replace the function of the partition, thereby solving the problem that the insulating body is not easy to form the partition at the second gap.
3. The elastic section of one differential signal terminal pair and the corresponding insulating attaching layer are contained in the terminal groove, one part of the insulating attaching layer is positioned between the two elastic sections of the differential signal terminal pair, the insulating attaching layer has a dielectric constant larger than air, mutual capacitance between the two elastic sections of one differential signal terminal pair is increased, the capacitance of one differential signal terminal to the whole external appearance is reduced, and crosstalk is reduced.
4. The insulating attaching layers are connected with the corresponding barriers along the arrangement direction of the conductive terminals, so that the insulating attaching layers between the two adjacent differential signal terminal pairs are as thick as possible, a larger capacitance effect is achieved between the two adjacent differential signal terminal pairs, and the crosstalk improvement effect is better.
5. The insulating attaching layer attaches the first surface of the elastic section of the differential signal terminal pair facing the butt joint element, so that the capacitance between the differential signal terminal pair and the transmission line in the butt joint element is increased, and the crosstalk between the differential signal terminal pair and the transmission line in the butt joint element is reduced.
6. The second surface of the elastic section of the differential signal terminal pair is exposed to the insulating attaching layer, so that a gap is formed between the second surface and the insulating body to ensure the elastic deformation of the elastic section.
7. The insulating attached layer is attached to the differential signal terminal pair in a spraying or transfer printing mode, and an independent die is not needed for molding the insulating attached layer, so that the manufacturing cost is saved.
8. The first part of the insulation attaching layer and the protruding part of the grounding sheet are positioned at two opposite sides of the elastic sections of the differential signal terminal pairs in a row, and the second surfaces of the elastic sections of the differential signal terminal pairs, which are back to the butting element, are exposed on the insulation attaching layer, so that after the grounding sheet is assembled to the terminal module, the insulation attaching layer can still be attached to the differential signal terminal pairs from the slot part to the first surfaces in a spraying or transfer printing mode; if the second surface is sprayed or printed with the insulating attaching layer, because the protruding part of the grounding piece covers a part of the elastic section in the horizontal direction, the second surface of the elastic section cannot be attached by the insulating attaching layer, so that impedance is easily discontinuous to cause resonance.
The above detailed description is only for the purpose of illustrating the preferred embodiments of the present invention, and not for the purpose of limiting the scope of the present invention, therefore, all the equivalent technical changes using the description and drawings of the present invention are included in the scope of the present invention.
