Description

Technical Field

[0001] The utility model relates to the technical field of photoelectric connectors, in particular to a docking device for photoelectric connectors. Background Art

[0002] Optical connectors, also known as optical active connectors, are passive devices used to connect two optical fibers or optical cables to form a continuous optical path. They have been widely used in optical fiber transmission lines, optical fiber distribution frames, and optical fiber test instruments and meters. They are the most widely used optical passive devices. Currently, there are many types of optical connectors, but the basic structure of various types of optical connectors is the same, that is, most optoelectronic connectors generally use high-precision components (consisting of two pins and a coupling tube, a total of three parts) to achieve the alignment and connection of optical fibers.

[0003] At present, when two photoelectric connectors are docked, the usual method is to align them directly and plug them in. In this way, the two photoelectric connectors are docked after being plugged in, thereby realizing the connection of the two optical fibers. However, there is a significant problem with this docking method: after the connection is completed, due to the lack of an effective fastening structure, when the optical fiber is pulled or subjected to external force, the docked photoelectric connectors are very likely to be detached, thereby affecting the normal transmission of optical signals and the stability of the entire optical communication system. In view of this, we propose a docking device for photoelectric connectors. Utility Model Content

A second spring 27 is sleeved on the slide bar 26, and one end of the second spring 27 is pressed against the clamp block 25. A connecting rod 21 is fixed at the opening of the bracket 20, and a first spring 22 is sleeved on the connecting rod 21. A movable seat 23 that can move horizontally is slidably installed on the connecting rod 21, and a detachable pressing ring 24 is installed above the movable seat 23.

The photoelectric connector 3 is clamped between the fixing groove 231 and the pressing ring 24, and the wiring harness of the photoelectric connector 3 passes through between two adjacent clamping grooves 251 and is clamped and fixed by the clamping grooves 251.

[0032] In this embodiment, the overall shape of the fixing groove 231 is arc-shaped, and a plurality of anti-skid grooves are provided on the top of the fixing groove 231. The arc-shaped design facilitates clamping the photoelectric connector 3 through the fixing groove 231, and the provision of the anti-skid grooves increases the fixing effect of the fixing groove 231 on the photoelectric connector 3.

[0033] In this embodiment, the front end of the double-ended screw 10 is coaxially keyed to an adjusting head 11, and a plurality of anti-slip grooves are provided on the outer wall of the adjusting head 11. The adjusting head 11 facilitates the rotation of the double-ended screw 10, thereby improving the convenience of operation.

[0034] In this embodiment, two guide rails 201 are fixed on the top of the bracket 20, and two slide grooves 232 are provided at the bottom of the movable seat 23 for sliding connection with the guide rails 201. The setting of the guide rails 201 guides the horizontal movement of the movable seat 23, ensuring the stability and smoothness of the movable seat 23.

[0040] When in use, the user first places the photoelectric connector 3 in the fixing groove 231 on one side, and places the pressure ring 24 on the top of the photoelectric connector 3. At this time, the user passes the fixing bolt 242 through the flap 241 and is threadedly connected to the movable seat 23, and the photoelectric connector 3 is fixed. Repeat the above steps and fix the photoelectric connector 3 on the other side; then the user pushes the clamping block 25 from the middle to both sides, and the clamping block 25 drives the slide bar 26 to move to both sides, and the second spring 27 is compressed. At this time, the user passes the wiring harness of the photoelectric connector 3 through the notch 204 and places it between the two clamping grooves 251, loosens the clamping block 25, and Under the action of elasticity, the clamping blocks 25 on both sides clamp and fix the wiring harness, and repeat the above steps to fix the wiring harness of the optoelectronic connector 3 on the other side; then the user rotates the adjusting head 11, and the adjusting head 11 drives the double-headed screw 10 to rotate. As the double-headed screw 10 rotates, the two connecting blocks 12 move synchronously toward the middle relative to each other, and the connecting blocks 12 simultaneously drive the bracket 20 and the optoelectronic connector 3 to move toward the middle. At this time, the optoelectronic connector 3 on one side is plugged into the optoelectronic connector 3 on the other side, and the movable seat 23 slides along the connecting rod 21, and the first spring 22 is compressed. When the docking between the two optoelectronic connectors 3 is completed, the user stops rotating the adjusting head 11.
