The structural design of the terminal box makes it meet the functional requirements

The terminal box is composed of three parts: the outer shell, the internal components, and the optical fiber connector protector. It has the functions of leading the optical cable, leading out the distribution pigtail and fixing and protecting the optical cable, the distribution pigtail and the performance of the optical fiber in it from being damaged. It has the function of protecting the fiber optic cable terminal from environmental influences. It has the function of insulating the metal components of the optical cable from the shell of the optical cable terminal box and conveniently leading out the ground. Provide the placement of the optical cable terminal and the remaining space for optical fiber storage, and make the installation and operation convenient. The box body can be fixed with sufficient impact resistance, and has corresponding installation functions for different usage occasions. When necessary, it should have the function of branching and connecting optical cables. The service life is up to 20 years.
The shell of the terminal box should be easy to open and easy to install; the shell should have a lead-out device for the high-voltage protective grounding of the metal components of the optical cable. The internal components of the terminal box should include the following parts: the support frame is the main body of the internal structure and is used for the support of the internal structure; The length of the cable should not be less than 1.6m, and the radius of curvature of the remaining optical fiber tray should not be less than 37.5mm. It also provides easy-to-identify fiber number marks and convenient operation space for reconnection; the fixing device is used for fixing the cable sheath, fixing the fiber optic cable strengthening member and fixing the pigtail.
