However, in this process, since the diameter of the optical fiber is not much different from that of the blind hole, when the optical fiber pushes the optical glue forward in the blind hole, the air that originally remained in the blind hole will be compressed due to the insertion of the optical fiber. , the compressed air will produce a resistance opposite to the forward direction of the optical fiber to the optical glue. When the resistance reaches a certain level, the optical glue will reverse along the forward direction of the optical fiber under the reverse push of the resistance generated by the compressed air, so that It will make it difficult for the glue to be evenly coated on the light-emitting surface of the optical fiber, so that the air gap between the light-emitting surface of the optical fiber and the bottom end of the blind hole cannot be effectively filled, and it is difficult to reduce the optical signal caused by the air gap. loss

Embodiment Construction
[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0014] Please also see figure 1 and figure 2 , the fiber coupling connector 100 provided by the embodiment of the present invention includes a housing 10 and a lens 20 .
[0015] The housing 10 has a substantially square main body 11 . The main body 11 has a first surface 111 and a second surface 112 oppositely arranged, and a third surface 113 and a fourth surface 114 connected to the first surface 111 and the second surface 112, the third surface 113 and the second surface The four surfaces 114 are arranged opposite to each other.
[0016] The main body 11 has four blind holes 115 arranged in parallel. The blind holes 115 extend from the third surface 113 to the fourth surface 114 and end at a position close to the fourth surface. The blind holes 115 are used to accommodate optical fibers (Fig. not shown).
[0017] The lens 20 is disposed on the fourt...

The invention relates to an optical fiber coupling connector comprising an outer shell, an optical fiber and a lens arranged on the outer shell. The outer shell is provided with a blind hole which is used for containing the optical fiber, the lens is arranged at the bottom of the blind hole and optically coupled with the optical fiber; the optical fiber coupling connector further comprises at least one vent hole arranged at the bottom end of the blind hole; and the vent hole is communicated with the blind hole to form a vent channel so that air in the blind hole is exhausted to the outside from the vent channel when the optical fiber is assembled into the blind hole. The invention also relates to an assembly method of the optical fiber coupling connector.
Description
technical field [0001] The invention relates to the field of Universal Serial Bus (USB), in particular to an optical fiber coupling connector and an assembly method thereof. Background technique [0002] The USB data transmission technology has been widely used, and USB coupling connectors of different technical standards have different data transmission rates. The current mainstream USB2.0 products in the market have a transfer rate of about 500MB / Sec, and the transfer rate of the next-generation product USB3.0 reaches 3?5G / Sec. The transmission media of these two products are metal wire transmission. [0003] In order to meet higher transmission requirements, fiber-coupled connectors with higher data transmission rates have emerged. A fiber-coupled connector generally includes a connector housing and a condensing lens disposed on the connector housing, and the connector housing includes a blind hole for inserting an optical fiber. Usually, the optical signal transmissio...
