Description

Technical Field

[0001] The invention relates to the field of electronics and communications, and in particular to a high-speed, low-loss connector with reliable elastic contact and an interconnection system. Background Art

[0002] In the connector system, when the devices are connected to each other, in order to ensure the reliability of the connection, each connection subsystem must be able to ensure good and reliable connection. The existing structure of single-point contact on a cross-sectional width of 0.2mm has the defects of contact slippage and low life. This contact on the cross-sectional edge is prone to jamming and poor contact quality, which can easily cause poor contact and distortion of high-speed signal transmission.

[0003] In order to solve the problem that the existing contact method uses 0.2mm width edges as the contact part, there is a great risk of the spring arm falling off and getting stuck. After calculation, when the edge of the contact part of another device in contact with the spring arm deflects by 1°, 75% of the area is in contact, and when it deflects by 2°, only about 50% of the area is in contact. At this time, there is a high probability of falling off under vibration and assembly errors, resulting in getting stuck or contacting with components with non-same functions, causing electrical transmission failure. This deflection of the contact part is because the device is formed by metal stamping. Due to stress and precision factors, according to the existing structure, its stress is difficult to eliminate, and improving the forming precision will greatly increase the cost; at the same time, impedance and crosstalk are very important considerations in high-speed connection systems, which directly affect the quality of electrical signal transmission. It is urgent to solve the shortcomings of the original pressure plate feature width and short guide, which lead to poor impedance adaptation, poor crosstalk and low guide ability.

[0004] For shielding components with EMI and EMC functions, in order to enable the shielding part to contact with the corresponding components well, in order to solve the problem that the spring piece in the original shielding layer has a snake head shape and a square shape that is opposite to the direction when docking, this state can easily lead to damage to the inserted component due to poor control of the size and angle of the spring arm, resulting in jamming. Summary of the invention

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide a high-speed, low-loss connector and an interconnection system with reliable elastic contact. The ground pin is designed as two opposite D-shaped structures to achieve side wall contact and the shielding layer is designed as an equilateral triangle spring sheet to contact the adjacent grounding terminal, thereby avoiding damage and jamming of the existing structure and reducing the risk of falling off. Spaced columnar protrusions are arranged to contact the ground pin; a conical plastic column is arranged to pass through the shielding body and the shielding layer is fixed by extruding the conical plastic column. The mutual contact of the ground pins and the grounding contact of the shield are used to isolate the periphery of the device differential signals from each other to achieve the purpose of EMI and EMC and improve crosstalk.

The plastic steps are L-shaped, and the right-angled surface thereof is arranged opposite to the female end shell. The female end shell is provided with an embedding groove for embedding the vertical end of the plastic step at a position opposite to each plastic step. An elastic body is arranged in the embedding groove opposite to the horizontal end of the plastic step, and the elastic body is bent toward the horizontal end of the plastic step for abutment.

10. A high-speed, low-loss interconnection system with reliable elastic contact according to claim 8, characterized in that: The thin sheet body is connected with the thin sheet body through an L-shaped limiting piece and an extrusion connection is adopted to realize the limiting fixation of each thin sheet body. The horizontal end of the L-shaped limiting piece is located at the top, and the horizontal end of the limiting piece is provided with a plug-in groove along the vertical direction. The upper part of the female end shell is provided with plug-in cavities at intervals to form plug-in columns. The plug-in columns are provided with rounded corners at the insertion head end for facilitating the embedding of the plug-in groove, and rounded edge protrusions are provided on both sides of the plug-in column.
