Improvement of connector structure

This creation is a cable connector with a PCI-Express Oculink interface with multiple plug slots.

In recent years, the rapid changes in technology, the rapid development of cloud technology, followed by the transmission of large amounts of data, at this time the connector transmission of information has become an indispensable key technology, currently, PCI-Express abbreviation (PCI-E The market has become more and more demanding on the size and cost of this type of connector product. For this, the PCI-E Oculink line end connector has been developed. This type of connector is designed for PCI-E internal applications and small data lines such as external devices. The initial data transfer rate is 8Gbps (1GB/S), which is further improved to 4 channel specifications of PCI-E. The Oculink line-end connector has a data transfer rate of up to 16 Gbps. The demand for high-speed information access technology solves the bottleneck of traditional parallel technology and provides faster signal transmission.

When the connector is designed and assembled, due to the large number of PCI-E Oculink interface terminals and the overall volume becoming smaller, how to overcome electromagnetic interference (EMI) in a limited space must be solved. When the number of terminals is large, the internal slot structure can be stably assembled, which has become an issue to be solved in the industry.

As shown in the sixth figure, Taiwan’s No. M517438 announcement patent application revealed The PCI-E line end connector comprises a conductive terminal A1, a plastic part A2, a back cover A3, an iron shell A4 and a PCB board A5, and the conductive terminal A1 is divided into two pieces, and the symmetrical pins are arranged on both sides of the plastic part A2 to form The assembly body; the rear cover A3 is engaged with the iron shell A4, and the assembly is accommodated in the inner space formed by the rear cover A3 and the iron shell A4; the PCB board A5 is matched with the rear end of the conductive terminal A1. The plastic part A2 includes a body A21 and a side piece A22. The rear end of the body A21 can be clamped in the back cover A3. The body A21 includes a card slot A23. The card slot A23 is disposed at the rear end of the plastic part A2, and the side piece A22 is set at the conductive terminal. In the middle of A1, the conductive terminal A1 is pressed into the body A21, and the side member A22 is simultaneously clamped in the card slot A23. The conductive terminal A1 includes the root portion A11. After the conductive terminal A1 is pressed into the body A21, the conductive terminals on both sides A1 is supported by the card slot A23, and the roots A11 are parallel to each other. The rear cover A3 includes a fastener A31, the fastener A31 is disposed outside the rear cover A3, the iron shell A4 includes a buckle hole A41, and the buckle hole A41 is disposed outside the rear end of the iron shell A4, when the rear cover A3 is engaged with the iron shell A4 The fastener A31 is fastened in the buttonhole A41.

When assembling the PCI-E Oculink line end connector, the root A11 of the conductive terminal A1 needs to be pre-pressed. The specific operation process is as follows: 1.

During the pressing process, the side members A22 themselves are also clamped in the card slot. A23, thereby realizing the fixing of the conductive terminal A1, and also achieving the effect of ensuring that the root portions A11 are parallel to each other.

However, in the foregoing technology, the PCI-E Oculink cable connector only relies on the side member A22 itself to be clamped in the card slot A23, thereby realizing the fixing of the conductive terminal A1, due to the size of the two structures in the snap-fit design. Most of the above designs are not tight assembly, and some buffer space is reserved to avoid errors in the manufacturing process.
