Description

Connector combination and pin connector thereof

[technical field]

The present invention relates to a kind of connector combination and pin connector thereof that improves signal transmission rate.

[background technology]

At the end of Year 2008, USB association has issued the USB standard of 3.0 versions, and this kind USB 3.0 connectors are to increase on the basis of original USB 2.0 connectors to be provided with two pairs of difference signal terminal and an earth terminal in order to improve the transmission rate of original USB connector.The transmission rate of this kind USB 3.0 connectors can reach the 5G per second, and can peg graft simultaneously USB 2.0 and USB 3.0 butt connectors.Yet, because conducting terminal quantity is more on USB 3.0 connectors, so that it is complicated to be connected in the cable internal structure of USB 3.0 rear sides, the problem such as the heavier and high frequency of cable and make it the longlyest only can arrange 5 meters, inconvenient consumer's use.In addition, the transmission speed of USB 3.0 connectors still can not satisfy the transmission demand of the large capacity electronic equipments such as similar blue-ray DVD.

For overcoming the problems referred to above, optical fiber is widely used in the telecommunications field gradually, replaces wire rope can reach low-loss, remote, the low laser propagation effect that disturbs by optical fiber.Thus, but but connector manufacturers respectively increase by an optical fiber module to form optical fiber USB socket connector and the optical fiber USB plug connector of a kind of not only transmitting optical signal but also transmission of electric signals on the basis based on USB socket connector and USB plug connector, this kind optical fiber USB socket connector or optical fiber USB plug connector not only can be electrically connected to satisfy with existing USB plug connector or USB socket connector the transmission demand of ordinary electronic equipment, also can carry out the transmission of high-speed optical signal to satisfy the signal transmission demand of the electronic equipment that carries out the high definition transmission by the optical fiber module simultaneously.Described optical fiber USB socket connector generally includes insulating body so that the optical fiber module of described transmitting optical signal to be set; The USB terminal is arranged on the described insulating body with transmission of electric signals; And metal shell coats described insulating body.Described metal shell comprises roof, the diapire relative with roof, connects two side and the receiving space between roof, diapire and two side of roof and diapire; described optical fiber module and USB terminal are exposed in the described receiving space; for so that after optical fiber USB plug connector inserts this optical fiber USB socket connector; both are docked reliably, one or some shell fragments can be set on the roof of this metal shell, diapire and the two side usually protrude into receiving space to increase the confining force with the pin connector shell.Yet; when optical fiber USB plug connector inserts this optical fiber USB socket connector; mechanical friction can occur and produce a large amount of metal break flours in the shell of these shell fragments and optical fiber USB plug connector, and these metal break flours usually can drop on the optical fiber module of socket and plug and affect the transmission quality of light signal.

So be necessary to provide a kind of have structure improved connector combination and pin connector thereof, to overcome defects.

[summary of the invention]

Technical problem to be solved by this invention is to provide a kind of connector combination and pin connector thereof of protecting fiber device.

For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of connector combination, and it comprises socket connector and the pin connector that matches with described socket connector; Described socket connector comprises jack body, is located at the optical fiber module on the jack body and coats described jack body and the metal shell of optical fiber module, described metal shell comprises roof, the diapire relative with roof, connects two side and the receiving space between roof, diapire and two side of roof and diapire, and described optical fiber module is exposed in the described receiving space; Described pin connector comprises header body, be located on the described header body and with the optical coupling of described optical fiber module with the fiber device of transmitting optical signal, coat described header body and fiber device cover shell and magnetic element, described magnetic element is located at and is describedly covered outside the shell and attract mutually with the metal shell of described socket connector.

A kind of pin connector, it comprises header body, be located at fiber device on the header body, coat covering shell and being located at the described magnetic element that covers outside the shell and be positioned at described fiber device rear of described header body and fiber device.

Compared with prior art, the present invention has following beneficial effect: magnetic element of the present invention utilizes the magnet principle to attract the metal shell of described socket connector, thereby make the mutual fixing of pin connector and socket connector, so that described pin connector is not easy to come off from described socket connector after inserting socket connector, therefore, the metal shell of socket connector need not to arrange the structures such as shell fragment of projection, thus phase mutual friction and produce that the metal break flour drops on the fiber device of socket connector and pin connector and the optical fiber module and the transmission that affects light signal when having avoided pin connector to insert this socket connector.
