Problems solved by technology

Consumes a lot of man-hour cost and grinding consumable cost
[0003] The injection molding of the ferrule adopts the method of high-precision pin insertion and injection molding, which requires high precision and position of the pin itself. To realize the application of single-mode optical fiber with low loss, it will bring the cost of mold development and injection molding very expensive
In addition, the guide pin hole of this type of ferrule is also adopted without chamfering through the hole. This structure will cause the surface material

Example Embodiment

[0021] The present invention will be further described below in conjunction with the drawings and embodiments.

[0022] Such as Figure 1 to Figure 2 Shown is a multi-channel V-groove optical coupling ferrule 100 in accordance with the present invention, which includes: an optical fiber aperture plate 11 and two guide pin hole barrels 12 located on both lateral sides of the optical fiber aperture plate 11. The hole barrel 12 is provided with a guide pin hole 13 penetrating in the front and rear direction, and the optical fiber hole plate 11 is provided with a row of optical fiber positioning holes 14. The optical fiber aperture plate 11 is recessed backward relative to the two guide pin hole cylinders 12, so as to reserve a working distance for laser cutting.

[0023] The guide pin hole cylinder 12 is provided with a front end surface 121 and a chamfer structure 122 located on the front end surface 121 of the guide pin hole cylinder 12. The thickness of the optical fiber aperture...

Abstract

The invention discloses a multichannel V-groove type optical coupling inserting core. The multichannel V-groove type optical coupling inserting core comprises an optical fiber hole plate and two guide pin hole cylinders locating on two transverse sides of the optical fiber hole plate, each guide pin hole cylinder is provided with a guide pin hole penetrating in the front and back direction, and the optical fiber hole plate is provided with a row of optical fiber positioning holes. The optical fiber hole plate is recessed backwards relative to the two guide pin hole cylinders, and then a working distance of laser cutting machining is reserved.

Description

technical field [0001] The invention relates to an optical coupling ferrule, in particular to a multi-channel V-groove optical coupling ferrule. Background technique [0002] The existing multi-channel fiber optic ferrule (Mechanical Transfer, MT-type ferrule for short) is all made of PPS material for injection molding. In practical applications, the front of the ferrule is processed by grinding, which needs to include: coarse grinding, fine grinding , Fine grinding, convex fiber grinding, polishing and grinding processes, including processing methods. It consumes a lot of man-hour cost and grinding consumable cost. [0003] The injection molding of the ferrule adopts the method of high-precision pin insertion and injection molding, which requires high precision and position of the pin itself. To realize the application of single-mode optical fiber with low loss, it will bring the cost of mold development and injection molding Very expensive. In addition, the guide pin ho...
