Abstract
Description
Technical Field
[0001] This utility model relates to an optical connector, specifically a multimode multicore non-contact optical connector. Background Technology
[0002] Existing connectors rely on direct physical contact between the fiber end faces (such as PC and APC end faces) to achieve optical coupling. Repeated insertion and removal operations can easily lead to scratches, wear, or dust / oil contamination of the end faces, significantly increasing optical signal loss. Long-term use results in a sharp drop in reliability, requiring frequent cleaning or replacement, and incurring high maintenance costs.
[0003] Harsh environments such as industrial and outdoor applications require connectors to have strong sealing properties. Existing designs mostly use a single sealing ring, but this cannot effectively prevent external dust and moisture from entering the fiber end face area. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a multimode multicore non-contact optical connector to solve the problems existing in the background art.
[0005] This utility model of a multimode multicore non-contact optical connector is achieved through the following technical solution, including an optical connector plug and an optical connector socket; The optical connector socket is provided with a connection hole, and the optical connector plug is inserted into the connection hole of the optical connector socket through a guide structure. Both the optical connector socket and the optical connector plug are equipped with optical fiber lines. When the optical connector socket is connected to the optical connector plug, the optical fiber lines are positioned correspondingly. Collimating lenses are provided at the corresponding ends of the optical fiber lines, and there is a gap between the collimating lenses, thereby achieving the effect of non-contact transmission.
[0006] As a preferred technical solution, the optical connector socket is provided with a locking structure and the optical connector plug is provided with a locking hole. When the optical connector socket and the optical connector plug are connected, the locking end of the locking structure is placed in the locking hole, thereby realizing the fixation between the optical connector socket and the optical connector plug.
[0007] As a preferred technical solution, the guiding structure includes guide grooves disposed on both sides of the optical connector plug and guide blocks disposed on both sides of the connection socket; When the optical connector plug is connected to the connection socket of the optical connector receptacle, the optical connector plug is guided by the guide groove and the guide block.
[0008] As a preferred technical solution, a stop is provided on the connector plug, and when the optical connector plug and the optical connector socket are inserted into place, the stop contacts the optical connector socket.
[0009] As a preferred technical solution, a first sealing structure is provided between the block and the optical connector socket, and a second sealing structure is provided at the optical fiber mounting positions of the optical connector plug and the optical connector socket; the connection sealing of the optical connector plug and the optical connector socket is achieved through the first sealing structure and the second sealing structure.
[0010] As a preferred technical solution, the first sealing structure includes a first sealing ring disposed on the outside of the block and the outside of the optical connector socket, and the sealing is achieved through contact between the first sealing ring and the first sealing ring.
[0011] As a preferred technical solution, the second sealing structure includes a second sealing ring and a sealing groove; The sealing groove is located on the outside of the optical fiber mounting position of the optical connector plug, and the second sealing ring is located on the outside of the optical fiber mounting position of the optical fiber connector socket. When the optical connector plug is inserted into the optical connector socket, the second sealing ring is placed in the sealing groove.
[0012] As a preferred technical solution, the locking structure includes a locking screw and a locking seat disposed on the optical connector socket; The locking screw is mounted on the locking seat, and the locking end of the screw passes through the locking seat and is placed inside the locking hole of the optical connector plug, thereby fixing the optical connector socket and the optical connector plug. The beneficial effects of this utility model are: This invention avoids the physical wear and contamination of the end face caused by repeated plugging and unplugging of traditional connectors through non-contact transmission, significantly improving the service life and reliability of the connector, eliminating optical loss fluctuations and instability caused by poor end face contact, and ensuring long-term stable optical signal transmission performance.
[0013] This invention, through the setting of a guiding structure and a collimating lens, ensures that the optical fibers in each channel can achieve high-precision spatial alignment in multimode multicore application scenarios, thus meeting the requirements of high-density connections.
[0014] This invention provides excellent dustproof, moistureproof, and liquid intrusion-proof capabilities through a double-sealing method, making the connector suitable for various harsh or easily polluted environments. Attached Figure Description
