technical field

The present invention relates to the field of Universal Serial Bus (USB), in particular to a mechanical component of an optical fiber coupling connector and an optical fiber coupling connector.

Background technique

USB data transmission technology has been widely used. For example, a USB coupling connector is used to connect a computer to a printer to complete printing work, or a removable storage disk is inserted into a computer USB jack through a plug-in USB coupling connector to realize data transfer.

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

Existing optical fiber coupling connectors usually include a plug mechanism and a receptacle mechanism. Although the plug mechanism and the receptacle mechanism are in a male-female butt relationship, they have different mechanical structures, so that they need to be adjusted separately during the production process. It carries out processes such as mold opening and measurement, which further increases production costs.

Detailed ways

Please refer to FIG. 1 and FIG. 2 , the optical fiber coupling connector 100 of the embodiment of the present invention includes a plug mechanism component 10 and a socket mechanism component 20 that are used together.

Please refer to FIG. 3 together. The plug mechanism 10 includes a first main body 11 and two first lenses 12 disposed on the first main body 11 .

Of course, the number of the first lenses 12 is not limited to two, and can be changed according to the requirements of the optical fiber coupling connector 100, for example, four, six, eight, and so on.

The first body part 11 is substantially in the shape of a cuboid, and has a first surface 111 and a second surface 112 opposite to each other. The first lens 12 is disposed on the second surface 112 with optical axes parallel to each other.

Two sides of the first main body 11 are integrally formed to form two first sidewalls 113 perpendicular to the first surface 111 , and the first sidewalls 113 have first wings 1130 thereon. One end of the two first sidewalls 113 close to the first lens 12 respectively has a first insertion hole 114 and a first post 115 .

The shape of the first post 115 can be cylindrical, truncated conical, conical, cuboid etc.; direction gradually decreases.

The first side wall 113 is elastic relative to the first main body 11 , and the first side wing 1130 is located in the middle of the first side wall 113 . When inserting the plug mechanism component 10 into the electronic device, pinch the two first side walls 113 to reduce the distance between the two to facilitate the assembly of the plug mechanism component 10, and the first side wings 1130 snap into the corresponding parts of the electronic device. The mating structure enables the plug mechanism component 10 to be fixed in the electronic device.

There are two first receiving holes 118 extending from the first surface 111 to the second surface 112 on the first main body 11 , and the number of the first receiving holes 118 corresponds to the number of the first lenses 12 . The first receiving hole 118 is used for receiving an optical fiber, and the central axis of the first receiving hole 118 coincides with the optical axis of the first lens 12 .

There is a first cylinder 116 between the two first receiving holes 118 , and the two first receiving holes 118 are symmetrically distributed with respect to the first cylinder 116 . The first cylinder 116 is used to position the two first receiving holes 118 , and the first receiving holes 118 are symmetrical with respect to the first cylinder 116 , of course, the first cylinder 116 can also be omitted.

There is a first positioning structure 117 between the two first lenses 12 , the first positioning structure 117 is a trapezoidal groove, and the geometric center coincides with the central axis of the first cylinder 116 .

The first positioning structure 117 is used to position the two first lenses 12 , of course, the first positioning structure 117 can also be omitted.

If the first lens 12 is an even number such as four, six, etc., the first positioning structure 117 divides them into two groups.

In addition, a first groove 119 is disposed on the first main body 11 , and the first groove 119 is parallel to the first surface 111 and the second surface 112 to expose part of the first receiving hole 118 to the outside. When the optical fiber is inserted into the first receiving hole 118 , a viscous medium such as glue can be filled in the first groove 119 to fix the optical fiber in the first receiving hole 118 .

Referring to FIG. 4 , the structure of the socket mechanism 20 is the same as that of the plug mechanism 10 , including a second main body 21 and two second lenses 22 disposed on the second main body 21 .

The second main body 21 has a second side wall 213 , a second post 214 , a second insertion hole 215 , a second column 216 , a second positioning structure 217 , a second receiving hole 218 and a second groove 219 . The second side wall 213 has a second side wing 2130 having the same function as the first side wing 1130 .

The structure of the second post 214 is the same as that of the first post 115, the structure of the second socket 215 is the same as that of the first socket 114, and the second post 214 is matched with the first socket 114, The second insertion hole 215 matches with the first post 115 .

When the shape of the first post 115 changes, the shape of the second post 214 needs to change accordingly, and at the same time, the shapes of the first jack 114 and the second jack 215 change accordingly, so as to ensure that the plug mechanism 10 The same structure as the socket mechanism member 20.

When the plug mechanism 10 is inserted into the socket mechanism 20, the first pole 115 is inserted into the second hole 215, and the second pole 214 is inserted into the first hole 114, so that the first lens 12 and the second lens The optical axes of 22 can overlap to ensure that the optical signal emitted from the first lens 12 or the second lens 22 can be normally transmitted to the other party.

Since the structure of the plug mechanism 10 and the socket mechanism 20 is the same, a single mold can be used to produce the plug mechanism 10 and the socket mechanism 20, thereby greatly reducing the cost of mold opening, measurement and equipment.

It can be understood that those skilled in the art can also make other changes within the spirit of the present invention to be used in the design of the present invention, as long as they do not deviate from the technical effects of the present invention. These changes made according to the spirit of the present invention should be included in the scope of protection of the present invention.
