Description

Technical Field

[0001] The utility model relates to the field of optical fiber communication, in particular to an optical cable optical unit sealing device. Background Art

[0002] The optical unit of the optical cable enters the interior of the box through the base hole of the junction box. The entrance of the chassis is sealed with liquid sealant, and then the clamp nut is tightened to achieve a sealing effect. The entrance of the optical unit of the existing junction box is sealed with liquid glue, which has the following defects: 1. The glue takes a long time to cure and may flow, resulting in poor sealing; 2. Liquid glue will corrode and deteriorate in performance under external conditions. 3. The glue injection process is performed on-site, and the sealing effect varies from person to person. At the same time, the sealant does not apply pressure and cannot guarantee the long-term stability of the seal. The above defects will destroy the sealing effect of the overall junction box, and long-term operation will damage the optical fiber, which will seriously affect line communications.
