Description

[0002] The optical cable junction box is a junction device that provides termination and jumpering for the trunk layer optical cable and the distribution layer optical cable. After the optical cable is introduced into the optical cable junction box, it is fixed, terminated, and fiber-matched, and then the trunk layer optical cable and the distribution layer optical cable are connected using jumpers. The optical cable junction box is a connection device installed outdoors. The most fundamental requirement for it is that it can withstand drastic changes in climate and harsh working environment. It must be resistant to water vapor condensation, water and dust, insect and rodent damage, and strong resistance to impact damage. It must be able to withstand relatively harsh external environments.

[0003] The existing optical cable junction box has certain disadvantages when in use. The box door of the traditional optical cable junction box has only a circle of rubber pads to play a role of sealing and waterproofing. The box door is closed by a door lock to close the box body and the box door. When closing, the rubber pad is squeezed to further achieve sealing. As the box body is used for a long time, the service life and sealing effect of the rubber ring will decrease, so dust and rainwater will easily enter the optical cable junction box. For this reason, the utility model proposes a waterproof and dustproof optical cable junction box, which achieves better waterproof and dustproof technical effects for the optical cable junction box by providing a sealed box door and a waterproof frame and a new sealing mechanism provided therebetween.
