Description

Fiber coupled connector

The present invention relates to a universal serial bus (USB), and more particularly to a fiber-coupled connector.

USB data transmission technology has been widely used, for example, the USB coupling connector is used to connect the computer to the printer to complete the printing work, or the removable storage disk can be inserted into the computer USB socket through the plug-in USB coupling connector for data transfer. .

USB-coupled connectors of different technical standards have different data transmission rates. For example, current USB 2.0 devices can run at 480 Mbps. As technology advances, fiber-coupled connectors with higher data transfer rates have emerged.

Conventional fiber optic coupling connectors typically include a connector housing and a concentrating lens disposed on the connector housing. A blind hole for inserting an optical fiber is usually included in the connector housing. In order to observe the assembly accuracy of the optical fiber, it is necessary to open a through hole at a corresponding position of the blind hole for observation. However, the presence of the vias affects the structural strength of the fiber-coupled connector as a whole, and its mechanical properties are affected.

In view of this, it is necessary to provide a fiber-optic coupling connector in which the structural strength is not affected and the flow resistance is reduced.

A fiber optic coupling connector includes a housing and a lens disposed on the housing The outer casing has a blind hole and a through hole penetrating the blind hole, the blind hole is for receiving an optical fiber, the lens is optically coupled with the optical fiber, and the through hole is provided with a rib for reinforcing the outer casing The strength of the rib is connected to the wall of the through hole by a lead angle.

Compared with the prior art, the through hole of the fiber-coupled connector of the embodiment of the present invention is provided with a rib, the rib is present such that the strength of the connector at the through hole is stronger than that without the rib, and therefore, the fiber-coupled connector is The structural strength is improved; in addition, the flow resistance can be reduced as the molten material flows due to the presence of the lead angle.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic illustration of a fiber optic coupling connector in accordance with an embodiment of the present invention.

2 is a schematic view of another angle of the fiber-coupled connector of the embodiment of the present invention.

Fig. 3 is a schematic view taken along line III-III of Fig. 2;

The invention will now be described in further detail with reference to the accompanying drawings.

Referring to FIG. 1, FIG. 2 and FIG. 3, the fiber-coupled connector 10 of the embodiment of the present invention includes a housing 11 and a lens 12.

The outer casing 11 has a substantially square body portion 110 and a grip portion 120 that is coupled to the body portion 110.

The main body portion 110 has a first surface 111 and a second surface 112 disposed opposite to each other, a third surface 113 and a fourth surface 114 connected to both the first surface 111 and the second surface 112, and the third surface 113 and the fourth surface 114 Relative settings.

The body portion 110 has two parallel holes 115 arranged in parallel, and the blind holes 115 are defined by the fourth surface 114. Extending to the third surface 113 and terminating near the third surface 113, the blind via 115 is used to receive the optical fiber.

Of course, the number of blind holes 115 can be changed according to actual needs, for example, four, six, eight, and the like.

The grip portion 120 is formed by extending a portion of the fourth surface 114 away from the third surface 113. When the fiber-optic coupling connector 10 is connected to an electronic device such as a notebook computer or a digital camera, the grip portion 120 is held and inserted. can.

The lens 12 is located at a position corresponding to the blind hole 115 of the third surface 113 for optical coupling with the optical fiber, and the third surface 113 is protrudedly provided with a connector end 116 for correcting alignment with the electronic device.

The main body portion 110 has a through hole 117 penetrating the first surface 111 and the second surface 112 at a position corresponding to the blind hole 115. The central axis of the through hole 117 is perpendicular to the central axis of the blind hole 115.

The through hole 117 extends inwardly adjacent to the hole wall of the second surface 112 to form a rib 1171. The rib 1171 is connected to the hole wall by a first transition angle 1172 which is smoothly transitioned, and the through hole 117 is adjacent to the hole wall of the first surface 111 to form a second hole. Lead angle 1173.

It can be understood that the hole wall of the through hole 117 near the first surface 111 may also extend to form a rib, and the rib is connected to the hole wall through the lead angle; the first lead angle 1172 and the second lead angle 1173 are round lead angles.

The through hole 117 of the fiber-coupled connector 10 is provided with a rib 1171. The presence of the rib 1171 allows the connector to have a higher strength at the through hole 117 than when the rib 1171 is not provided. Therefore, the structural strength of the fiber-coupled connector 10 is obtained. Increasing; in addition, due to the presence of the first lead angle 1172 and the second lead angle 1173, the flow resistance can be reduced as the melt flows.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention. Equivalent modifications or variations made by persons skilled in the art in light of the spirit of the invention are intended to be included within the scope of the following claims.
