Abstract

A fiber coupling connector comprises a first body and second bodies. The first body comprises a first surface, a second surface which is opposite to the first surface, a third surface and a fourth surface which is opposite to the third surface. The first surface is concave in the direction of the second surface to form grooves which can deposite the second bodies. The third surface possesses lenses and the second bodies possess through holes. The through holes are used to take in fibers. The lenses are optically coupled with the fibers. The second bodies are glued in the grooves. Optical axes of the lenses are same with center axes of the through holes. The invention also provides a manufacturing method of the fiber coupling connector.

Description

Optical fiber coupled connector and manufacture method

Technical field

The present invention relates to a kind of optical fiber coupled connector and manufacture method.

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 and finishes print job, or removable storage disks is inserted computing machine USB jack with 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.

Optical fiber coupled connector (generally being divided into public connector and female connectors) comes transmission information by optical fiber, and it comes correcting and fixed fiber by blind hole.The optical fiber coupled connector of difference needs the optical fiber of varying number, and then needs the blind hole of respective numbers, then needs to go into son with the moulding blind hole according to the different different dies of optical fiber coupled connector design.Die is gone into son for consumptive material in actual production, loses easily in production run, and cost accounts for quite big proportion, in addition because die is gone into son in the device for injection moulding process, impacts and causes die to go into the son bending and then influence optical signal transfer because of melting material easily.

Summary of the invention

In view of this, be necessary the optical fiber coupled connector and the manufacture method that provide a kind of.

A kind of optical fiber coupled connector, it comprises first body and second body, described first body has first surface, with described first surface opposing second surface, the 3rd surface with relative the 4th surface, described the 3rd surface, described first surface is recessed to form the groove of accommodating described second body to described second surface, described the 3rd surface has lens, described second body has through hole, described through hole is used for up-winding fiber, described lens and the coupling of described fiber optics, described second body is glued in the described groove, the optical axis of described lens and the spigot shaft coaxle of described through hole.

A kind of optical fiber coupled connector manufacture method, described optical fiber coupled connector comprises first body and second body, have lens and groove on described first body, described second body has through hole, described through hole is used for up-winding fiber, and described optical fiber and the coupling of described optics of lens, described second body is positioned at described groove, and described optical fiber coupled connector manufacture method comprises: adopt first device for injection moulding to make described first body; Adopt second device for injection moulding to make described second body, utilize die to go into the described through hole of sub-moulding; Described second body is glued in the groove of described first body.

Compared with prior art, first body that the optical fiber coupled connector of the embodiment of the invention has lens is the structure of two independences with second body with up-winding fiber structure, and employing first shaped device is made first body in manufacture process, second shaped device is made second body.This measure can design first shaped device and second shaped device respectively, and then when manufacturing has other optical fiber coupled connector of same fibre number, second shaped device can reuse, and can only design first shaped device, thereby shortens design process and reduce design cost.Owing to change blind hole into through hole, in the ejection formation process, the die of forming through hole can be gone into sub fixing in addition, be not easy distortion, also in the ejaculation process, be difficult for causing die to go into the sub crooked optical signal transfer that influences because of melting the material impact thereby make die go into son.

Embodiment

Below in conjunction with accompanying drawing the present invention is described in further detail.

See also Fig. 1, Fig. 2 and shown in Figure 3, the optical fiber coupled connector 10 that the embodiment of the invention provides comprises first body 11 and two second bodies 12.

First body 11 have first surface 111, with first surface 111 opposing second surface 112, the 3rd surface 113 and four surface 114 relative with the 3rd surface 113.Wherein, first surface 111 links to each other with the 4th surface 114 with the 3rd surface 113.

First surface 111 is recessed to form two grooves 110 to second surface 112, and the profile of groove 110 is identical to be used for holding second body 12 with the shape of second body 12.

All have two through holes that are arranged in parallel 120 on each second body 12, through hole 120 is used for up-winding fiber.

Have lens 13 on the 3rd surface 113 of first body 11, the spigot shaft coaxle of the optical axis of lens 13 and through hole 120, and the coupling of the fiber optics on the lens 13 and second body 12.

The quantity of second body 12 can adjust according to actual needs, for example has only one second body 12, perhaps more a plurality of second bodies 12.

Certainly, the quantity of the through hole 120 on second body 12 can also suitably change according to optical fiber coupled connector 10 needed optical fiber numbers, for example on each second body 12 through hole 120 or more a plurality of through hole 120 is set all.

In addition, can will have second body 12 of a through hole 120, two through holes 120 or more a plurality of through hole 120 as standard component, when making different structure optical fiber coupled connector 10, only need the device for injection moulding of design different size moulding first body 11 to get final product, and the die that does not need to design forming through hole 120 is simultaneously gone into son, and then has shortened the processing procedure time and reduced manufacturing cost.

When making optical fiber coupled connector 10, adopt first device for injection moulding to make the die that first body, 11, the first device for injection moulding have shaping groove 110; Adopt second device for injection moulding to make the die that second body, 12, the second device for injection moulding have forming through hole 120 and go into son; Then second body 12 is bonded in the groove 110 of first body 11.

Adopt first shaped device to make first body 11 in manufacture process, second shaped device is made second body 12, this measure can design first shaped device and second shaped device respectively, and second shaped device can reuse, and then when manufacturing has other optical fiber coupled connector of same fibre number, can only design first shaped device, thereby shorten processing procedure and reduce cost.

Because, the blind hole of fixed fiber changes through hole 120 into, the die of forming through hole 120 can be gone into son and fix in the ejection formation process, therefore, die is gone into son and is not easy distortion, also is difficult for causing die to go into the crooked optical signal transfer that influences of son because of melting the material impact in the ejaculation process.

In addition, those skilled in the art can also do other variation in spirit of the present invention, and certainly, the variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
