Abstract
A kind of line construction of high speed frequency class transmission cable component, described cable-assembly includes one group of flat cable and PCB, the flat cable is suppressed with the outer mold piece that flat cable is crimped together and is integrally formed with PCB with the junction of PCB, described line construction connects with the rearward end of the PCB including flat cable leading section and at inserted sheet end of the PCB leading section formed with slotting company, it is characterized in that the PCB internal circuit that is at least provided with one side at the inserted sheet end communicates with the corresponding lead of flat cable, in a townhouse pin of be set with side by side, it is right that 25 pairs of side band lines positions are designed to high-frequency line position on the townhouse pin, and grounding design therebetween is independent grounding wire position；It has simple in construction, and easy to use, interface is frivolous, electric circuit design optimization, broadness, the features such as can be suitably used for greater demand occasion.
Description
Technical field
The present invention relates to a kind of line construction of high speed frequency class transmission cable component, especially unmasked type are anti-interference
The line construction of data cable component, the transmission of information in the systems such as data center, cloud computing, data storage is primarily adapted for use in,
Belong to communication technical field.
Background technology
The connection interfaces of interface newest structure-SlimLine SAS 4.0 of existing SAS classes cable-assembly, be primarily present as
Lower two problems：First, PCB is in assembly forming, the position inaccurate in die cavity；And signal transmission interface unicity compared with
By force, compatibility is poor；In traditional PCB design, there are 5 couples of sidebands respectively（Sideband）Line position, it is low frequency wire
Position；If it is designed to as high-speed signal transmission lines position, while the requirement of compatible sideband function again, so to it
In the related electric function of this group of high speed signal pair need independent use；In PCB, the middle ground of this group of line position is set
Meter is independent, can not connect effect jointly with whole PCB circuit loops, therefore the cost of PCB can be increased, correlation merit
It is it is required that higher.
The content of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and it is reasonable to provide a kind of structure composition, user
Just, interface is frivolous, electric circuit design optimization, broadness, can be suitably used for greater demand occasion, the phase such as be particularly suitable for use in SAS, PCIe
Close the high speed frequency class transmission cable modular construction of agreement transmission.
The purpose of the present invention is completed by following technical solution, a kind of circuit of high speed frequency class transmission cable component
Structure, described cable-assembly include the circuit of one group of flat cable and PCB, the flat cable and PCB
Junction is suppressed with the outer mold piece that flat cable is crimped together and is integrally formed with PCB, described line construction
Connect including flat cable leading section with the rearward end of the PCB and in PCB leading section formed with slotting company
Inserted sheet end, it is characterised in that the inserted sheet end is at least provided with PCB internal circuit and flat electricity on one side
The corresponding lead of cable communicates, the townhouse pin in be set with side by side, is all provided with 25 pairs of side band lines positions on the townhouse pin
Count into that high-frequency line position is right, and grounding design therebetween is independent grounding wire position.
As preferred：Described pcb board is with golden finger corresponding relation；
Golden finger PIN definition is defined as PIN1, PIN2, PIN3 ... PIN35, PIN36, PIN37 from left to right；
Pad PIN definition is defined as PIN1, PIN2, PIN3 ... PIN35, PIN36, PIN37 from left to right；
Corresponding line is corresponds, i.e. golden finger PIN1- pads PIN1, golden finger PIN2- pad PIN2, golden finger PIN3-
Pad PIN3 ... golden finger PIN35- pad PIN35, golden finger PIN36- pad PIN36, golden finger PIN37- pads PIN37.
The invention belongs to improvements over the prior art, and reasonable with structure composition, easy to use, interface is frivolous, electrically electricity
Road design optimization, broadness, can be suitably used for greater demand occasion, the related protocol such as be particularly suitable for use in SAS, PCIe transmit the features such as.

Portion connects and is at least provided with inserted sheet end 4 of the leading section of PCB 2 formed with slotting company, the inserted sheet end 4 on one side
Communicated by the internal circuit of PCB 2 with the corresponding lead of flat cable 1, the townhouse pin in be set with side by side, described
25 pairs of side band lines positions 5 are designed to high-frequency line position is right, and grounding design therebetween is independent grounding on townhouse pin
Line position, the performance requirement of high frequency signal transmission was so both can guarantee that, and can compatibility low frequency signal sidebands functional requirements should
With broader.
Fig. 2, shown in 3, described pcb board is with golden finger corresponding relation；
Golden finger PIN definition is defined as PIN1, PIN2, PIN3 ... PIN35, PIN36, PIN37 from left to right；
Pad PIN definition is defined as PIN1, PIN2, PIN3 ... PIN35, PIN36, PIN37 from left to right；
Corresponding line is corresponds, i.e. golden finger PIN1- pads PIN1, golden finger PIN2- pad PIN2, golden finger PIN3-
Pad PIN3 ... golden finger PIN35- pad PIN35, golden finger PIN36- pad PIN36, golden finger PIN37- pads PIN37；
The line position arrangement of specific signal path is as shown in Figure 3.
