Description

The optical fiber coupled connector

Technical field

The present invention is about a kind of optical fiber coupled connector.

Background technology

The usb data transmission technology has been able to widespread use, for example, adopts the USB coupled connector that computing machine and printer are coupled together the completion print job, or removable storage disks is inserted computing machine USB jack by plug-in type USB coupled connector realize the data transfer.

The USB coupled connector of different technologies standard has the different pieces of information transfer rate.For example, existing USB2.0 equipment can move with 480Mbps.Along with development of technology, having more, the optical fiber coupled connector of high data rate arises at the historic moment.

The optical fiber coupled connector comprises plug and socket, and the material of plug and socket is a plastic material, and plug and plug have integrated lens respectively, and locatees each other through the location structure that is provided with above that.

Because plug and socket is plastic material, have elasticity, lens can make the butt joint degree of depth of lens different because of the size of butt joint strength in butt joint, and then influences the uncertain of distance between the lens, and transfer efficiency is therefore instability also.

Summary of the invention

In view of this, be necessary to provide the optical fiber coupled connector that distance is confirmed between a kind of lens.

A kind of optical fiber coupled connector; It comprises plug and the socket that is complementary with said plug; First lens that said plug has first optical fiber and is coupled with said first optical fiber; The end that said plug has said first lens has reference column, said socket comprise second optical fiber and with second lens of the said second optical fiber even coupling, the end that said socket has said second lens has the pilot hole that matches with said reference column; Said reference column is provided with at least one projection, has at least one groove that matches with said at least one projection on the hole wall of said pilot hole.

Compared with prior art, when the plug of the optical fiber coupled connector of the embodiment of the invention docked with socket, projection propped up behind the bottom of groove, can confirm plug and socket butt joint location, also can guarantee the distance between the plug and socket simultaneously.

Embodiment

To combine accompanying drawing that the embodiment of the invention is done further explain below.

See also Fig. 1 and shown in Figure 2, the optical fiber coupled connector 10 that the embodiment of the invention provides comprises the plug 11 and socket 12 that is separated from each other setting.Wherein, socket 12 is located at equipment such as main frame, printer, camera, and plug 11 is portable, is used for cooperating with socket 12, and data are inputed or outputed to aforementioned device.

Plug 11 adopts four optical fiber outputs or receives signal, and correspondingly, 12 of sockets adopt the transmission of signal between four optical fiber realizations and the plug 11.

Certainly, the number of optical fiber can change according to actual needs.

Plug 11 roughly is square, and corresponding four optical fiber, an end of plug 11 are provided with four first lens, 13, the first lens 13 and are used for output or receive signal with the fiber optics coupling, and first lens 13 are one-body molded with plug 11.

Socket 12 roughly is square, corresponding first lens 13, an end of socket 12 be provided with that the coupling of four second lens, 14, the second lens 14 and fiber optics is used to realize and plug 11 between the signal transmission, second lens 14 are one-body molded with socket 12.

The end that plug 11 has first lens 13 is provided with reference column 110, and reference column 110 is conical, and the diameter of reference column 110 reduces to the direction away from plug 11 gradually.

Reference column 110 on the corresponding plug 11; Socket 12 offers pilot hole 120 at an end that is positioned at second lens 14; The diameter of pilot hole 120 increases to the direction away from socket 12 gradually, thereby makes a less end aligned hole 120 diameter larger parts of reference column 110 diameters insert pilot hole 120.Reference column 110 inserts pilot holes 120 and makes the optical axis coincidence of the lens 13 and second lens 14 of winning, and makes to win and have certain distance between the lens 13 and second lens 14 with coupling optical signal preferably.

Certainly, reference column 110 also can be other shape, and is for example cylindrical, correspondingly, and the corresponding change of the shape of pilot hole 120.

Reference column 110 is provided with a projection 111 away from the side of first lens 13, and projection 111 is formed to the less end extension of diameter by the maximum end of reference column 110 diameters.Corresponding projection 111; Have groove 121 on the hole wall of pilot hole 120, when plug 11 docked with socket 12, projection 111 propped up behind the bottom of groove 121; Can confirm first lens 13 and second lens, 14 butt joint location, also can guarantee the distance between first lens 13 and second lens 14 simultaneously.

Certainly, projection 111 also can be arranged on other position of reference column 110, and for example reference column 110 is near a side of first lens 13, the perhaps centre position of reference column 110.

Certainly, the shape of projection 111 can be different shape, for example cylindrical, rectangular parallelepiped, cone etc.

The number that is appreciated that projection 111 is not limited to one, can be two, three, four etc.When number during more than or equal to two, projection 111 is evenly distributed on the reference column 110.

The length of projection 111 is not limit; Its length is less than the length of reference column 110, for example can be reference column 110 length etc.

Certainly, when the shape of projection 111, position, number, length, when the regularity of distribution changes, the groove 121 on the pilot hole 120 also must correspondingly change, and in other words, the quantity of projection 111 equates that with the quantity of groove 121 projection 111 is corresponding one by one with groove 121.

Be appreciated that when projection 111 when a plurality of, groove 121 can be an annular groove on the hole wall that is arranged on pilot hole 120.

It is understandable that those skilled in the art also can do other variation etc. and be used for design of the present invention in spirit of the present invention, as long as it does not depart from technique effect of the present invention and all can.These all should be included within the present invention's scope required for protection according to the variation that the present invention's spirit is done.
