In the figure: SVG power unit body 1, SVG power unit fiber interface 2, optical fiber connector seat 3, optical fiber plug 4, dust cover 5, the dust cover body 51, cable via hole 52, laminating hem 53, installation hem ear 54, mounting hole 55, set screw 6, dust joint 7, silicone tube 8, optic fibre 9.

Detailed Description

As shown in fig. 1-5, an air-cooled SVG power unit optical fiber interface dust prevention device comprises a dust cover 5, a dust joint 7 and a silicone tube 8, wherein a cable via hole 52 is formed in the dust cover 5, the cable via hole 52 is in threaded connection with the front end of the dust joint 7, the silicone tube 8 extends into the rear end of the dust joint 7 and wraps an optical fiber cable, and the edge of the front end of the dust cover 5 is attached to and detachably connected with the SVG power unit body 1.

As shown in fig. 3, the optical fiber plug 4 can pass through the through hole of the dust cap 7 and the through hole 52 of the cable and is connected with the optical fiber connector base 3, the edge of the dust cap 5 is attached to the SVG power unit body 1 to prevent dust from invading into the optical fiber plug 4 from the edge, the through hole 52 of the cable is sealed by being connected with the front end of the dust cap 7, the through hole at the rear end of the dust cap 7 is filled by the silicone tube 8, and the problem of the locking of the dust cap caused by the size inconsistency of the optical fiber plug 4 and the optical fiber cable is solved.

The dust cover 5 has the structure that: including the dust cover body 51 that is the cuboid casing, dust cover body 51 one end is uncovered, and other end side is equipped with cable via hole 52, and both sides are equipped with laminating hem 53 about the uncovered end, and the left and right sides is equipped with the installation and rolls over ear 54, and the installation is rolled over and is equipped with mounting hole 55 on the ear 54, and fixed screw 6 passes mounting hole 55 and with SVG power unit body 1 fixed connection.

The attaching structure of the attaching folding edge 53 and the attaching folding ear 54 enables the dustproof cover body 51 to be closely attached to the SVG power unit body 1, the rectangular shell structure provides enough structural rigidity when being convenient for manufacturing steps such as folding edge welding, and the like, and plays a role in protecting joints.
