Connector mould 100 manufacturing method thereofs of group of bright design are simple, are suitable for large-scale industrial production, yield is controllable, finished product service life
It is long.
It please refers to shown in Figure 23, for the high speed interconnecting assembly 400 that the present invention discloses, the high speed interconnecting assembly 400 includes
There are two pieces of circuit boards 200, a connector mould group 100 and two socket connectors 500 being separately fixed on each circuit board 200
(an also settable socket connector 500), and the cable 3 of the connection connector mould group 100 and socket connector 500.
Certainly, in other embodiments, also it can pass through connector mould group 100 in the not same lateral position of same circuit board 200
Cable 3 is cooperated to realize signal transmission with socket connector 500.
Certain foregoing circuit plate 200 can be any currently known printed circuit board, or be equipped with certain mating chip
The printed circuit board of (not shown), or can be the physical layer device of any other surface installation as known in the art.
500 correspondence of socket connector can be docked with external optical module (not shown), to realize external optical module (light
Cable-end) to the high speed transmission of signals of board side, so that module high speed signal passes through socket connector 500, cable 3, connector
Mould group 100, the copper foil cabling on circuit board 200 enter mating chip.
Connector mould group 100 in the design can accomplish more to minimize with respect to conventional jack connector (not shown),
Height dimension can control within 3.5mm, has lower height, connector mould group 100 is allowed to be installed in mating
The lower section of the radiator of chip, therefore connector mould group 100 can be made closer to the mating chip (target element for needing to connect
Part), to reduce connector mould group 100 to the signal transmission distance between mating chip, transmission loss can be reduced, so may be used
To reduce requirement to circuit board material while guaranteeing high speed transmission of signals demand, can be used for example it is more common it is low at
This material (such as FR-4) circuit board substitutes high-end and high-cost (such as M7) material circuit board, greatlys save cost.In addition
200 wiring space of circuit board can be greatlyd save, the space utilization rate of circuit board is improved.In addition the design connector mould group 100
Transmission density it is high, per square centimeter area, which can design, reaches seven differential pairs (i.e. seven pairs of signal terminals 22), each difference
Divide to highest operating rate up to 56Gbps, and there are also bigger transmission rates to promote potential.Certainly, the height in the design
The overall transmission rate of fast interconnecting assembly 400 also needs the performance of matching cable 3, circuit board 200, mating chip on circuit board.
Furthermore the design connector mould group 100 is cell configuration, that is to say, that the quantity of differential pair can be extending transversely, solves tradition
Socket connector cooperates plug connector terminals quantity extension bring technical difficulty and performance to influence.
The socket connector 500 can be known QSFP-DD (Quad Small Form-factor Pluggable
Double Density) connector.The socket connector 500 generally comprises connector assembly (not labeled), covers at connection
The metal cap 51 of device assembly periphery and the radiating module 52 for being mounted on 51 top of metal cap.The connector assembly has generally comprised
Insulating part (not labeled) and several female terminal (not labeled) fixed with insulating part.The insulating part and metal cap 5 are common
It encloses to set to define and is formed with grafting space 501, and interface 502 is formed by 5 one end of metal cap.Each female terminal generally comprises
There is the female terminal fixed part (not labeled) being fixed in insulating part, extended in grafting space 501 by female terminal fixed part
Female terminal contact portion (not labeled) and extend the female terminal docking section (not labeled) of insulating part by fixed part.If described
Stem socket terminal is divided into several high speed receptacle signal terminal (not labeled) and several non-high-speed receptacle signal terminals (are not marked
Number).Realize that signal passes by above-mentioned cable and connector mould group 100 in the female terminal docking section of the high speed receptacle signal terminal
Defeated, the female terminal docking section of the non-high-speed receptacle signal terminal is directly realized with the copper foil cabling docked on circuit board 200
Signal transmission.
The above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to preferred embodiment to this hair
It is bright to be described in detail, those skilled in the art should understand that, it can modify to technical solution of the present invention
Or equivalent replacement, without departing from the spirit and scope of the technical solution of the present invention.
