Description

Technical Field

[0001] This utility model mainly relates to the field of communication devices, and in particular to an optical fiber connector. Background Technology

[0002] Existing fiber optic connectors, especially those with a cable fixing section at the tail, primarily use this section to secure the fiber optic cable. The cable fixing section is connected to the connector's housing for secure attachment. The cable fixing section is typically square for easy insertion and fixation. Most existing cable fixing sections have a cover, usually L-shaped, to enclose and secure the cable. This cover is typically 180 degrees to the groove of the cable fixing section. Since the cover and the groove are at a 180-degree angle, a 180-degree fold is required for them to snap together. However, the cable fixing section is usually made of plastic and is relatively small. The pivot or hinge between the cover and the cable fixing section is fragile and prone to breakage after repeated use, requiring materials with high toughness. Utility Model Content

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1 and Figure 2 As shown, a fiber optic connector includes a housing 1 with a through-cavity. The front half 2 of the cavity accommodates a fiber optic fixing assembly 36. A spring arm 4 extending rearward is located near the front end of the housing 1. The rear of the spring arm 4 has a receiving opening 5. The fiber optic fixing assembly 36 is provided with a locking block 6 having a right-angled surface facing forward and a sloped surface facing rearward. Thus, the fiber optic fixing assembly 36 can be inserted from front to back, pushing open the spring arm 4 to allow the fiber optic fixing assembly 36 to enter the front half 2 of the cavity. After the locking block 6 enters the receiving opening 5, its position is restricted to ensure that the fiber optic fixing assembly 36 has a certain amount of movement in the front-rear direction. The spring arm 4 abuts against the right-angled surface of the locking block 6 to block it. A spring 7 of the fiber optic fixing assembly 36 abuts against a step 8 of the front half 2 of the cavity. The housing 1 has a tapered passage 9 facing the fiber optic fixing assembly 36 for the passage of the fiber optic cable. The rear body of the housing 1 is square and is provided with a locking slot 10 and an observation window 11.

[0017] like Figure 3As shown, the fiber optic fixing assembly 36 mainly includes a housing 12, a cover 13, a clamping spring 14, a spring 15, and a ceramic ferrule 16. The ceramic ferrule 16 is located at the front end of the housing 12. The spring 15 is sleeved on the tail tube 17 of the housing. A V-groove 18 is provided in the middle of the housing 12. The cover 13 is used to fasten onto the housing 12. The clamping spring 14 is used to clamp the housing 12 and the cover 13 to clamp the optical fiber located within the V-groove 18. The clamping spring 14 applies clamping force at the connection point between the optical fiber and the pre-embedded optical fiber 19. The ceramic ferrule 16 of the fiber optic fixing assembly 36 extends out of the housing 1 and is used for communication.

[0018] like Figure 4 and Figure 5 As shown, the optical cable fixing part 3 is detachably disposed within the tail portion of the housing 1. The optical cable fixing part 3 has an optical cable fixing groove 20 and a cover 21. The optical cable fixing groove 20 is configured to be through-hole and has an open surface that allows the optical cable to enter from the outside. The cover 21 is configured to be flat and is foldable onto the optical cable fixing groove 20 via a hinge 22. The cover 21 can open or close the open surface to surround and fix the optical cable from all sides. The cover 21, the optical cable fixing groove 20, and the hinge 22 are integrally molded. The cover 21 is configured to be positioned along the direction in which the optical cable enters the optical cable fixing groove 20. That is, during integral injection molding, the cover 21 is at a 90-degree angle to the open surface. Thus, when folded later, the cover 21 can be rotated 90 degrees to achieve a fastening. For different optical cable models, a gasket 23 can be provided to accommodate optical cables of different diameters. The gasket 23 is configured to be inserted into the bottom of the optical cable fixing groove 20 from the top, i.e., the open side. The optical cable fixing part 3 is provided with spring arms 24 on both sides, and the spring arms 24 have locking blocks. The spring arms cooperate with the locking slots 10 of the housing 1 so that the optical cable fixing part 3 can be detachably installed in the tail of the housing 1. The optical cable fixing groove 20 is provided with spikes or locking strips 28 for fixing the optical cable.

[0019] The cover 21 has strip-shaped locking holes 25, and cover locking ribs 26 are provided on the inner wall of the strip-shaped locking holes of the cover 21. The optical cable fixing part 3 is provided with fixing part locking ribs 27. The cover 21 is opened or locked by the cooperation of the cover locking ribs 26 and the fixing part locking ribs 27. Thus, when the cover 21 is fastened to the optical cable fixing part 3, the fixing part locking ribs 27 do not protrude from the outer side of the cover 21, that is, after fastening, there is no protrusion at the fastening position that prevents the optical cable fixing part 3 from being inserted into the tail of the housing 1, and the two cooperating locking ribs are hidden in the thickness direction of the cover 21.

[0020] like Figure 6 As shown, the optical cable fixing groove 20 can also be configured to have a first fixing groove 29 near the front end and a second fixing groove 30 near the tail end. The first fixing groove 29 and the second fixing groove 30 correspond to two different diameter optical cables, and the depth of the second fixing groove 30 is greater than the depth of the first fixing groove 29.

[0021] like Figure 7 and Figure 8 As shown, the back of the fixed-length tool bar 31 has a groove for accommodating the optical cable fixing part 3. After the optical cable with optical fiber is installed on the optical cable fixing part 3, it is placed on the back and the coating layer on the optical fiber is stripped by the coating layer stripper 34. By pulling the optical cable, the optical cable and the optical cable fixing part 3 are moved outward together, thereby removing the coating layer.

[0022] The length-fixing tool bar 31 has a cable fixing part receiving groove 32. After the coating layer is removed, the optical cable with optical fibers and the cable fixing part 3 are fixed to the cable fixing part receiving groove 32, and then the optical fibers on the optical cable are cut to a fixed length. The cable fixing part 3 installed in the housing 1 is the cable fixing part 3 after the cable fixing part 4 is fixed to the length-fixing tool bar 31 and the optical fibers on the optical cable are cut to a fixed length. In this way, the end of the length-fixing tool bar 31 can be provided with a clamping arm 35, which is used to help remove the cable fixing part 3 from the housing 1.
