Technical field

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

Background technology

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

The USB coupled connector of different technologies standard has different pieces of information transfer rate.For example, existing USB2.0 equipment can move with 480Mbps.Along with the progress of technology, there is the more optical-fiber coupling connector of high data rate and arise at the historic moment.

Optical-fiber coupling connector (being generally divided into public connector and female connectors) carrys out transmission information by optical fiber, and it comes correcting and fixed fiber by blind hole.The optical-fiber coupling connector of difference needs the optical fiber of varying number, and then needs the blind hole of respective numbers, needs to design different dies according to different optical-fiber coupling connectors and enters son with moulding blind hole.In actual production, die enters son for consumptive material, in production run, easily loses, and cost accounts for quite large proportion, and in addition because die enters son in device for injection moulding process, easily because melting material is impacted, to cause die to enter son crooked and then affect optical signal transfer.

Summary of the invention

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

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

A kind of optical-fiber coupling connector manufacture method, described optical-fiber coupling connector comprises the first noumenon and the second body, on described the first noumenon, there is lens and groove, described the 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 the second body is positioned at described groove, described optical-fiber coupling connector manufacture method comprises: adopt the first device for injection moulding to manufacture described the first noumenon, described the first noumenon has first surface, the second surface relative with described first surface, the 3rd surface and four surface relative with described the 3rd surface, described groove is caved in to described second surface by described first surface, the 3rd surface of described the first noumenon has described lens, adopt the second device for injection moulding to manufacture described the second body, utilize die to enter through hole described in sub-moulding, described the second body is glued in the groove of described the first noumenon, and the optical axis of described lens is coaxial with the central shaft of described through hole.

Compared with prior art, the lensed the first noumenon of optical-fiber coupling connector tool of the embodiment of the present invention is the structure of two independences with second body with up-winding fiber structure, adopts the first shaped device manufacture the first noumenon, the second shaped device to manufacture the second body in manufacture process.This measure can design respectively the first shaped device and the second shaped device, and then when manufacture has other optical-fiber coupling connector of same fibre number, the second shaped device can reuse, and can only design the first shaped device, thereby shortens design process and reduce design cost.Owing to changing blind hole into through hole, in ejection formation process, the die of forming through hole can be entered to son fixing in addition, thereby make die enter son, be not easy distortion, also in ejaculation process, be difficult for impacting and causing die to enter the crooked optical signal transfer that affects of son because of melting material.

Embodiment

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

Refer to shown in Fig. 1, Fig. 2 and Fig. 3, the optical-fiber coupling connector 10 that the embodiment of the present invention provides comprises the first noumenon 11 and two the second bodies 12.

The first noumenon 11 has first surface 111, the second surface 112 relative with first surface 111, the 3rd surface 113 and four surface 114 relative with the 3rd surface 113.Wherein, first surface 111 is connected 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 the second body 12 with the shape of the second body 12.

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

On the 3rd surface 113 of the first noumenon 11, have lens 13, the optical axis of lens 13 is coaxial with the central shaft of through hole 120, and the coupling of the fiber optics on lens 13 and the second body 12.

The quantity of the second body 12 can adjust according to actual needs, for example, only have second body 12, or more the second body 12.

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

In addition, can be using second body 12 with a through hole 120, two through holes 120 or more through hole 120 as standard component, while manufacturing different structure optical-fiber coupling connector 10, only need to design the device for injection moulding of different size moulding the first noumenon 11, and do not need the die that simultaneously designs forming through hole 120 to enter son, and then shortened the processing procedure time and reduced manufacturing cost.

When manufacturing optical-fiber coupling connector 10, adopt the first device for injection moulding to manufacture the die that the first noumenon 11, the first device for injection moulding have shaping groove 110; Adopt the second device for injection moulding to manufacture the die that the second body 12, the second device for injection moulding have forming through hole 120 and enter son; Then the second body 12 is bonded in the groove 110 of the first noumenon 11.

In manufacture process, adopt the first shaped device manufacture the first noumenon 11, the second shaped device to manufacture the second body 12, this measure can design respectively the first shaped device and the second shaped device, and the second shaped device can reuse, and then when manufacture has other optical-fiber coupling connector of same fibre number, can only design the first shaped device, thereby shorten processing procedure and reduce costs.

Due to, the blind hole of fixed fiber changes through hole 120 into, the die of forming through hole 120 can be entered to son fixing, therefore in ejection formation process, die enters son and is not easy distortion, also in ejaculation process, is difficult for impacting and causing die to enter the crooked optical signal transfer that affects of son because of melting material.

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