Connector Assemblies and Electronics

technical field

Background technique

In the current communication equipment system, an interconnection system based on a printed circuit board (Printed Circuit Board, PCB for short) combined with a daughter card is the most common interconnection architecture. As the connection bridge between the backplane and daughter cards, the connector acts as a key fabric-level component. For high-speed electrical signal transmission, the loss and crosstalk performance of connectors have an important impact on the transmission performance of high-speed links.

In order to improve the anti-crosstalk performance between the differential signal pairs between the signal modules, at present, in the connector used to realize the backplane connection, the signal modules and the shielding modules are arranged in a staggered combination. Each signal must have a return current, and the shielding module is used as the return path of the signal current, which makes the design of the shielding module particularly important. In order to enable the shielding module to provide a good return path and reduce or avoid the occurrence of insertion loss resonance, in the prior art, the shielding module is designed in the form of a shielding sheet to reduce the occurrence of insertion loss fluctuation and resonance. At the same time, since the shielding sheet is located between the signal modules, the crosstalk shielding effect between the signal modules can be achieved.

However, when the size of the shield is limited, especially when the signal of the signal module (such as a differential signal pair) is close to the edge of the shield, the fringing field outside the edge of the shield can still cause coupled crosstalk between signals.

Connector: generally refers to an electrical connector, that is, a device used to connect two active devices. After the connector is connected to the two active devices, current or signals can be transmitted between the two active devices.

Crosstalk: mainly refers to the coupling phenomenon between two signal lines. Due to the close spatial distance of the signal lines, there will be inductive and capacitive coupling between the two, which will interfere with each other. As the transmission rate of the signal transmitted by the connector increases, a certain crosstalk phenomenon may occur between the signal lines of the connector, which affects the integrity of signal transmission. Therefore, reducing and reducing the signal crosstalk and loss in the connector is one of the problems to be solved urgently in the connector design.

Shielding module: The shielding module refers to the grounding unit in the basic chip unit module with the connectors arranged in the direction parallel to the mounting substrate. The unit contains a plurality of metal leads and has a common ground network property.

Differential signal: It is a numerical value to express the difference between two physical quantities. Differential signal, also known as differential mode signal, is relative to common mode signal. A differential signal is a pair of symmetrical signals of equal magnitude and opposite polarity, and differential signals are used to transmit useful signals. Differential transmission signal can play a strong anti-interference ability to external interference.

Popular signal transmission technology for high-speed signal interconnection. In the prior art, the current typical high-speed signal transmission generally adopts the NRZ mode, and the rate can generally reach 25 Gbps. Among them, NRZ refers to the non-return to zero code (Non-Return to Zero, abbreviated as: NRZ), and the digital signal can directly use the baseband. transmission. Baseband transmission is the direct transmission of electrical pulses of digital signals in the line, which is the simplest transmission method. At present, the local area network of short-range communication adopts baseband transmission.

For application scenarios currently under development that need to support high-speed signal transmission (such as 56G to 112Gbps transmission speed), the PAM4 mode is generally used for transmission. However, the use of PAM4 mode transmission will have higher requirements on the integrity of the signal when the high-speed connector is transmitted. Generally, it is necessary to shield the adjacent signals of the connector in all aspects to improve the integrity of the transmitted signal. Therefore, the connector assembly provided by the embodiments of the present application can solve the problem of signal crosstalk between adjacent signals in the contact area of the connector during high-speed signal transmission, so as to improve the integrity of the transmitted signal.

A ring-shaped closed shielding structure is formed on the periphery, which can completely shield the plug-in area after the first connector 1 and the second connector 2 are plugged, and the reverse magnetic flux generated by the oscillating magnetic field energy caused by the impedance mismatch. Suppression strengthens the isolation of electric field energy, reduces mutual inductance between loops, and weakens inductive coupling noise, thereby reducing crosstalk between adjacent signals and improving signal integrity during high-speed transmission.
