Description
Technical Field
The invention relates to the technical field of optical fiber communication, in particular to an optical fiber adapter and an optical fiber connection structure.
Background
In order to solve the problem, the conventional optical fiber adapter (for example, an LC type optical fiber adapter) is configured to include two parts, namely an input end and an output end, and the input end and the output end of the adapter are welded together by ultrasonic welding after the optical component is installed in a cavity of the input end and the output end.
However, the above-described design has the following problems: when the adapter is fixed, the connector inserted into the adapter exerts a stress of disengagement on the welding point under the action of a pretension force, so that the input end and the output end are separated after working for a period of time. In view of this, several types of solutions are proposed on the market: (1) by separating the input end optical assembly holder separately, the technical problem that the input end and the output end are fixedly connected by welding is avoided (patent number: CN207281343U or CN 201876570U); (2) the technical problem that the input end and the output end are fixedly connected in a welding mode is solved by simultaneously arranging the input end optical assembly holder and the output end optical assembly holder in a split mode (patent numbers: CN109884750A, CN102289039A or CN 102520488B).
However, the above solutions introduce two technical problems at the same time: (1) the input end optical assembly holder and the output end optical assembly holder are spliced in a post-assembly mode, due to manufacturing errors and assembly errors, axial center dislocation is easily caused between the input end optical assembly holder and the output end optical assembly holder, so that a floating space of an optical assembly in a cavity of the input end optical assembly holder and the output end optical assembly holder is reduced, or a collimation sleeve bears large stress generated by the axial center dislocation from the input end optical assembly holder and the output end optical assembly holder, and the optical assembly is easily damaged; (2) the dimensions of the input optical assembly holder and the input structural support are very difficult to control and stress is easily generated when the connectors are mated, which results in large connector losses (this problem is defined in detail in IEC61754-20 Figure5-simple adaptor interface section for J-dimension, and any feature associated with J-dimension that is mounted in an indeterminate position increases the uncertainty of J-dimension).

As shown in fig. 8 to 10, the present embodiment provides another optical fiber adapter based on the technical solution of the first embodiment, and the difference between the optical fiber adapter of the first embodiment and the optical fiber adapter of the first embodiment is that: the input end accommodating cavity 111 and the output end accommodating cavity 211 are both O-shaped accommodating cavities, the opening structure is located at the input end side end or the output end side end of the integrated contour structure and comprises an end surface opening with a corresponding end and a stop member, wherein the stop member is the input end stop member 112 or the output end stop member 212; the optical component 400 is inserted into the interior of the one-piece profile structure through the end-face opening of the respective end and in the unobstructed state before the stop is formed, and then the socket profile on the respective side is reshaped, resulting in a stop formed at the respective end. As shown in fig. 8 to 10, for example, before the optical component 2 is shaped to obtain the output-end stop member 212, since the end-face opening at the output end is in an unobstructed state, the optical component can be conveniently inserted into the end-face opening and the output-end accommodating cavity 211 in sequence, so as to achieve the purpose of being externally installed into the O-shaped accommodating cavity, and then the output-end stop member 212 functioning as a similar cover plate is shaped, so that the optical component 400 is located in the internal cavity of the adapter body without escaping, thereby providing another method and assembly structure for facilitating processing and manufacturing. Specifically, the shaping method may be, but not limited to, an existing shaping method including a local thermal melting shaping process, a local ultrasonic shaping process, or a local laser cutting shaping process, as shown in fig. 9, a thermal melting shaping tool 50 is used to perform the local thermal melting shaping process, and then the stop member formed at the output end is obtained.
