【Specific embodiment】
Various embodiments of the present invention are high-frequency electric connecter, and the high-frequency electric connecter includes upper and lower two rows high-frequency signal terminal and the shield between two row's high-frequency signal terminals.Current electric connector high frequency signal terminal typically uses differential terminal pair, such as the electric connector such as USB Type C, HDMI, DisplayPort, Thunderbolt uses differential terminal to transmission high-frequency signal.Traditional piece way for ground wire of a holding wire, differential transfer simultaneous transmission of signals in both threads are different from, and the amplitude of two signals is identical, opposite in phase.In current transmission rate more and more higher（Such as each channel transfer 10Gbps）, size it is less and less（Such as terminal is smaller than 0.5 millimeter）In the case of, the coupled interference between upper and lower row signal is increasingly severe.
Fig. 1 to Fig. 3 simulates a pair of differential lines（T+、T-）（Function is equivalent to differential terminal pair）With ground connection layers of foil SP（Function is equivalent to shield）Between position relationship to insertion loss（Differential Insertion
Loss）Influence.In Fig. 1, a pair of differential lines are set on a circuit board PCB（T+、T-）With ground connection layers of foil SP, the differential line is 4mil (1mil=0.0254 millimeters) with the distance between layers of foil H is grounded, i.e. H=1.016 millimeters, impedance is 100 ohm.When layers of foil SP is grounded using copper product or stainless steel material, as shown in Fig. 2 S11 shows the insertion loss that layers of foil is grounded using stainless steel material, S21 shows that copper product is grounded the insertion loss of layers of foil for the simulation drawing of insertion loss, as can be seen that conductance copper higher（Conductance is 80%）Obtain a relatively good insertion loss, and stainless steel material（Conductance is 4%）Then obtain a undesirable insertion loss.In figure 3, increase the differential line (T+, T-) and be grounded the distance between layers of foil SP, H is 8mil, that is H1=2.032 millimeters, obvious copper product ground connection layers of foil SP remains unchanged than stainless steel ground connection layers of foil has more preferable insertion loss, but both gaps are obviously reduced, such as when transverse axis is 10GHz, S22 is substantially better than S21.By above-mentioned simulation insertion loss, illustrate that ground connection layers of foil is smaller with the distance of differential line, insertion loss from desired value more away from, now influence of the conductance of ground connection layers of foil SP to insertion loss is also bigger, ground connection layers of foil conductance is more high then more effective to improving insertion loss, and the principle is applied to differential terminal pair and shield.
Fig. 4 to Fig. 6 shows the USB Type C socket connectors 100 with high frequency differential terminal pair, the metal shell 40 that the socket connector 100 includes insulating body 10, two row's terminals 20, shield 30 and is coated on outside docking hyoplastron, insulating body includes base portion 12 and the docking hyoplastron 11 extended from base portion, and the metal shell docks chamber 101 with dock to be formed between hyoplastron.Two row's terminals 20 are tabular and are docking two contact sites of apparent surface 21 of hyoplastron and extending the pin 22 of insulating body with exposed, the shield 30 is fixed in insulating body and between two row's terminals 20, and shield 30 is extended in base portion 12 from hyoplastron 11 is docked.The docking hyoplastron 11 has two the two of apparent surface sides 111 of connection, and the shield 30 has exposed two lock lateral margins 311 in docking hyoplastron side.The often row terminal include USB2.0 signal terminals to, ground terminal, power supply terminal and USB3.1 signal terminals be the differential terminal pair of transmitting high-frequency signal to 24, USB3.1, the material strip 23 between the terminal that wherein Fig. 6 shows can be removed in the final product.Fig. 7 shows the simulation insertion loss of the upper and lower row's terminals of USB3.1, and S is the loss numerical value that USB Type C connector specifications specify, used as a reference value；When shield 30 is using copper product, the insertion loss S31 of the upper row USB3.1 and insertion loss S32 of lower row USB3.1 is satisfied by requiring；When shield 30 still uses stainless steel material, the insertion loss S41 of the upper row USB3.1 and insertion loss S42 of lower row USB3.1 is also satisfied by requiring.However, when carrying out high frequency experiment for product material object and analyzing, the test data of stainless steel shield 30 can not meet demand as shown in figure 8, the insertion loss S51 of USB3.1 is less than a reference value S that specifications specify interlude A at；When stainless steel shield 30 carried out in two apparent surface it is gold-plated（Preferably, two apparent surfaces of this shield in kind are integrally gold-plated for the conductance of gold）Afterwards, the insertion loss S61 of USB3.1 is above a reference value S, meets and requires.
The shield 30 can be by the material of high conductivity, such as directly manufacture is formed copper alloy etc., it is also possible to coat the material of high conductivity, such as gold, silver etc. on its surface.In most preferred embodiment, as shown in fig. 6, shield 30 includes base plate 31 and is coated in two coatings of apparent surface 32 of base plate, the base plate 31 is stainless steel material, and coating 32 is the metal material of high conductivity.The coating can fill two apparent surfaces of whole base plate, it is also possible to topical application, but at least fill with two rows differential terminal to the part alignd and including pin（The dash area of the meaning of label 32 as shown in Figure 6, that is, define the differential pair terminal correspondence and form shadow region in shield, and the coating at least coats the shadow region）.The coating of the shield can also be formed using other high conductivity materials, such as copper, silver wait until that conductance is at least above 10% material.Compared to copper product shield, the shield of gold-plated rust Steel material has relatively good intensity because of its stainless steel plate, can provide preferable snap action, and the structure that shield 30 is embedded in the docking hyoplastron of insulating body can also strengthen the intensity of docking hyoplastron.Also one most of all, stainless steel material adds this infrastructure cost of coating also very low.To sum up, influence of the shield 30 to differential terminal pair is mainly the conductance on its surface, in the present invention, the upper and lower apparent surface of the shield at least has the conductance higher than stainless steel material conductance, including being formed by coating or formed by whole base plate, the conductive material of the coating of high conductivity for conductance more than 10%.
