Description

Fiber coupled connector

The present invention relates to the field of 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.

Existing 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-coupled connector in which the structural strength is not affected.

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, a central axis of the through hole is perpendicular to a central axis of the blind hole, and the lens is located at a bottom end of the blind hole, and the blind hole is used for The optical fiber is housed, and the inner side of the through hole is provided with ribs in the radial direction for reinforcing the strength of the outer casing.

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.

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 first 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 which are disposed opposite to each other in the axial direction, a third surface 113 and a fourth surface 114 which are connected to both the first surface 111 and the second surface 112, and the third surface 113 and the fourth surface The surfaces 114 are oppositely disposed.

The body portion 110 has two axially and parallelly arranged blind holes 115, that is, the blind holes 115 extend from the fourth surface 114 toward the third surface 113 and terminate near the third surface 113. The blind hole 115 is used to receive an optical fiber (not shown). The grip portion 120 is formed by extending 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 or a digital camera, the grip portion 120 can be inserted and inserted.

The lens 12 is located at a position corresponding to the blind hole 115 of the third surface 113, and the third surface 113 is protrudedly provided with the insertion end 116.

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, that is, the central axis of the through hole 117 is perpendicular to the central axis of the blind hole 115. When the optical fiber group is loaded into the blind hole 115, the assembly of the optical fiber can be observed through the through hole 117.

The inner wall of the through hole 117 is radially protruded to form a strip-shaped first rib 118 and a second rib 119. The first rib 118 and the second rib 119 are both parallel to the third surface 113, that is, the first rib 118 and the second rib 119 are The main body portion 120 is integrally formed. Therein, the first rib 118 is adjacent to the first surface 111, and the second rib 119 is adjacent to the second surface 112, and both have a sufficient distance for the optical fiber to pass through. Since the first rib 118 and the second rib 119 serving as supporting members are provided in the through hole 117, the structural strength of the main body portion 110 can be enhanced.

Of course, the number of blind holes 115 can be changed according to actual needs, for example, four, six, eight, and the like. Each of the blind holes 115 is provided with a through hole 117 at a corresponding position, and each of the through holes 117 has a first rib 118 and a second rib 119 disposed therein.

As shown in FIG. 4, the basic structure of the fiber-optic coupling connector 20 of the second embodiment of the present invention is basically the same as that of the fiber-optic coupling connector 10, and the difference is that the through hole Only one first rib 218 is disposed within the 217, and the first rib 218 is perpendicular to the third surface 213.

The first rib 218 is separately formed and then glued into the through hole 217 with glue, the material of which may be the same as or different from the fiber coupling connector 20.

Of course, the first rib 218 may not be perpendicular to the third surface 213, and may have any angle between the two, such as 30 degrees, 60 degrees, and the like.

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.
