Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1 to 7, the multi-service signal optical transceiver includes a housing 3, a jack 2, and a connection line 13. The shell 3 is provided with a U-shaped wire fixing frame 4. The wire fixing frame 4 is composed of a connecting shaft 41 and a clamping plate 42. The connecting shaft 41 is fixedly connected with the housing 3. The thread clamping plate 42 is provided with threading holes 6 with the same number as the thread insertion openings 2. A pressing plate 5 is arranged in the threading hole 6, and a telescopic shaft 7 is arranged on the upper surface of the pressing plate 5. The telescopic shaft 7 is in threaded connection with the clamp plate 42, and the upper end of the telescopic shaft 7 is provided with a rotating handle 71. Rotating the rotating handle 71 drives the pressing plate 5 to move up and down. The connecting shaft 41 is provided with a line-extending frame 1, the line-extending frame 1 is provided with a placing rod 11, and the placing rod 11 is parallel to the shell 3. The two ends of the placing rod 11 are provided with sliding blocks 111, and the sliding blocks 111 are connected with the delay line frame 1 in a sliding manner through the first sliding rail 12, so that the placing rod 11 can move up and down along the first sliding rail 12. The bottom of the sliding block 111 is provided with a telescopic spring 112, the upper end of the telescopic spring 112 is fixedly connected with the sliding block 111, and the lower end is fixedly connected with the connecting shaft 41. The left side of the shell 3 is provided with a ventilation grid 9, and a baffle plate 8 is arranged outside the ventilation grid 9. The shielding plate 8 is connected with the shell 3 in a sliding way through a sliding rail II 10. The shutter 8 is provided with a handle 14. The handle 14 is pulled, and the shielding plate 8 can be moved left and right to shield or open the ventilation grid 9. The right side of the housing 3 is provided with a heat sink 15.

As shown in fig. 5, the pressing plate 5 which can move up and down is arranged on the threading hole 6, so that the height of the threading hole 6 can be adjusted, the threading hole is matched with the connecting wires 13 with different thicknesses to penetrate through, and the effect that the pressing plate 5 extrudes and fixes the connecting wires 3 is also achieved.

The arrangement of the ventilation grids 9 and the radiating fins 15 can greatly improve the radiating effect. When the optical transceiver is not in a working state, the shielding plate 8 can be used for covering the ventilation grid 9, so that the dustproof effect is achieved.

As shown in fig. 4, in the actual use process, the connecting wire 13 penetrates through the threading hole 6, then the extended connecting wire 13 is hung on the placing rod 11, then the extended connecting wire 3 is inserted into the wire inserting opening 2, the reserved length of the connecting wire 3 between the wire inserting opening 2 and the threading hole 6 is longer than the actual connecting length, so that the connecting wire 3 between the wire inserting opening 2 and the threading hole 6 is in a bent state, and finally the rotary handle 71 is rotated to enable the pressing plate 5 to move downwards until the connecting wire 13 is pressed and fixed. When being affected by external force, the connecting wire 13 is stretched outwards, and the connecting wire 3 cannot be separated from the wire inserting opening 2 because the connecting wire 13 is fixed on the clamping plate 42. If the dynamics ratio of external force leads to connecting wire 13 and clamp plate 5's extrusion to appear not hard up, lead to being located connecting wire 13 between plug wire mouth 2 and the through wires hole 6 also by outside stretching, then connecting wire 13 is to placing pole 11 extrusion downwards, expanding spring 112 also follows the downward compression, then expanding spring 112's the extension power that resets can be to placing pole 11 downstream production resistance, the outside extension force of connecting wire 13 has further been combatted, it breaks away from plug wire mouth 2 to hinder connecting wire 13. Therefore, under the double security of the clamping plate 42 and the placing rod 11, the probability that the connecting wire 13 is separated from the wire plugging port 2 is greatly reduced.
