Description
Technical field
The present invention relates to a kind of structure-improveds of line-end connector, and espespecially the plural contact terminal of insulating base frame is to be connected with
Transmission cable, make its source line group time interval one apart from and be dislocated arrangement, can avoid contacting with each other cause short circuit or electricity
It flows through load and causes superheating phenomenon, and use biggish line footpath, its power loss and heating effect can be reduced to load high current.
Background technique
It presses, electronics technology is grown up now with speed with rapid changepl. never-ending changes and improvements, so that computer kenel is to be developed by desktop computer
Small volume and notebook computer easy to carry, and the upper each corner of generally existing society, and electronic device design is all at present
It is intended to light, thin, short, small, and in order to make the volume-diminished of electronic device, connector assembly inside electronic device just need to be with
Substantially reduce, in response to current development trend, the lower thin connector and general wire rod of phase shape or the company of flexible circuit board
It connects and fixes, it will certainly be more difficult.
When electronic device data signal transmission to be carried out, or when connecting with other peripheral equipments, that is, need so-called week
Edge equipment interface, and general peripheral equipment interface is the most universal and widely masses are used, still with universal serial bus
(USB) it is used as mainstream, and utilization USB supports the function plug and play of hot plug, makes use upper more easy, due to now
USB3.0 connector has sufficiently been used in various external peripheral equipment, and in the challenge for facing other high speed interfaces, Bian You manufacturer
USB3.1Type-C interface specification is released, mainly dimensionally, support higher power source charges smaller than existing connector and confession
Electric energy power, and transmission speed may be up to 10Gbps, can be inserted using upper support front and back sides allow user will no longer be required to differentiate it is positive and negative
Except face, can more it expand on the electronic device suitable for light and thin types such as Smartphone, tablet computers, therefore especially by market
On expectation.
Since electronic device volume is smaller and smaller so that the connector structure inside electronic device then need it is more accurate and small
Type, overall structural strength also need to reinforce therewith, and general board to board connector, wire pair board connector etc. would generally utilize a public affairs
Terminal adapter carries out cooperation with a terminative connector and docks, and signal and/or power supply are sent to control electricity by circuit board
Lu Zhong to execute corresponding operation function, and is very different in USB3.1 connector and previous USB connector design,
System uses the pattern that row up and down exists simultaneously terminal, and as the downsizing of USB3.1 connector and transmission speed substantially mention
Rise, increase its numbers of terminals and be distributed it is more intensive, it is extremely easy to cause high-frequency signal to pass because getting too close between terminals of adjacent
Signal interference (such as Electromagnetic Interference (EMI), cross-talk) when defeated, the conduction for causing USB3.1 connector itself to be subject to are dry
Disturbing and/or radiate interference problem will be more serious.
Furthermore the terminal group of Male end connector and terminative connector mostly quantity is fixed, and is designed for transmission signal
And/or power supply uses, and the space configuration for terminal group entirety that how to make appropriate arrangements in the limited space of pedestal, and importing
The function of power supply is transmitted, also will be the key point for influencing more minimize in connector design, only the USB3.1 connection
The row terminal system up and down of device is connect in the way of welding with the metallic contact at printed circuit board front, and extremely by connection
The plural core wire of metallic contact and cable at rear welds, make to arrange up and down terminal grounded parts can by printed circuit board with
The ground connection core wire of cable forms a circuit being grounded jointly, although the metallic contact wiring connection type letter of such printed circuit board
Singly it is easy to make, but there is still a need for assembled and welded journey by printed circuit board in the connection because arranging terminal and cable up and down
Sequence not only causes whole fabrication schedule complex and comparable consuming working hour and cost, and printed circuit board configuration also can
Certain volume is occupied, to cause connector overall dimensions not reduce effectively, just is wanted to study to engage in this journey dealer
Improved key point.

With the first side arm 211, ejection makes its elastic arm in the contact portion 522 of conductive terminal 52 to the conductive part 21 of contact terminal 2 separately down
5221 strut and conductive part 21 enters in the elastic space 5220 of elastic arm 5221, and by the positioning convex point of conductive part 21 outward
213 be held in elastic arm 5221 support end 5222 on, with increase between terminal supporting contact strength and form certain electrical property and connect
Connect, at the same by the side plate of shield shell 4 42 separately down ejection on the positioning snap-on 534 of metal shell 53, make position snap-on
534 form lock state via being held on holding part 421 respectively after flexible deformation and the process of reset, to realize the present invention
The electrical property of line-end connector and plate terminal adapter 5 dock.
In the present embodiment, when the conductive terminal 52 of the contact terminal of line-end connector 2 and plate terminal adapter 5 contacts,
The conductive part 21 of the contact terminal 2 of its partial will with the second side arm 212 separately down ejection in the ground connection of metal shell 53
Elastic slice 532, and make grounding elastic slice 532 towards 5221 direction of elastic arm of conductive terminal 52 in a flexible deformation, and to line-end connector
Positioning is pressed to, six grounding elastic slices 532 can be supported to be contacted on contact terminal 2 respectively and increase by a current conduction path,
And cooperate corresponding third branch spare terminal and the six, the nine, 12,15,18 ground terminals in 2 definition of pin position of contact terminal
Son supports the common earth-return circuit for being contacted with and forming Multi-contact in conductive terminal 52 respectively, is promoted so that its impedance is effectively reduced
Path and density when electric current transmits, and supporting between contact terminal 2 and the conductive terminal 52 of plate terminal adapter 5 can be increased and contacted
Strength is not likely to produce loosening or break-off after docking it.
When plate terminal adapter 5 cooperates line-end connector when transmitting high-frequency signal, generated electromagnetism involves each other
Cross-talk can contact at respectively contact terminal 2 by the grounding elastic slice 532 of metal shell 53, and contradict contact terminal 2 respectively
The common earth-return circuit of Multi-contact is formed on corresponding ground terminal in 52 definition of pin position of conductive terminal, and shielding can be passed through
The contact flat spring 413 of shell 4, which is overlapped in incude on the earth plate 312 that transmission cable 3 is located above signal line group 31 respectively, to be inhaled
It receives, while being held on the holding part 421 of shield shell 4 by the positioning snap-on 534 of metal shell 53, and support elastic slice
535 contact on side plate 42 and carry out ground connection release, can be effectively reduced when it transmits high-frequency signal each other because distance is close
Generated electromagnetism involves the interference such as cross-talk, and the grounding elastic slice 532 of metal shell 53 can also be according to its 2 foot of partial contact terminal
Corresponding ground terminal, the position of spare terminal or the change setting of non-usb signal terminal and quantity, can match splice grafting in the definition of position
The common earth-return circuit that contravention 2 forms Multi-contact reduces signal interference, so keep the signal transmitting quality more stable and
Reliably.
