The DIN-type optical cable terminal box relates to a fiber optic termination box that can be installed and used in confined spaces. A DIN-type optical cable terminal box includes a box body, a cover plate, a fiber splicing tray, a fiber splicing bracket, a fiber splicing module, an adapter mounting plate, cable entry holes, strength member fixing clamps, and DIN clips. The box body is a hollow square box, with side plates perpendicular to the bottom surface on both sides and the rear end. Between the two sides and the rear side of the box body, there are oblique chamfered surfaces, which are also perpendicular to the bottom surface of the box body. The front side of the box body is the adapter mounting plate. On the inner wall of the box body's bottom surface, a fiber splicing bracket is fixedly connected, and at the upper end of the fiber splicing bracket, there is a connection device used to fixedly connect the fiber splicing tray. The upper surface of the fiber splicing tray is fixedly connected with a fiber splicing module. At the rear side of the box body, there are DIN clips, allowing the box body to be easily snapped into a predetermined position during installation.

1. A DIN-type optical cable terminal box,

Characterized by: comprising a box body, a cover plate, a fiber splicing tray, a fiber splicing bracket, a fiber splicing module, an adapter mounting plate, cable entry holes, strength member fixing clamps, and DIN clips. The box body is a hollow square box, with side plates perpendicular to the bottom surface on both sides and the rear end. Between the two sides and the rear side of the box body, there are oblique chamfered surfaces, which are also perpendicular to the bottom surface of the box body. The front side of the box body is the adapter mounting plate. On the inner wall of the box body's bottom surface, a fiber splicing bracket is fixedly connected, and at the upper end of the fiber splicing bracket, there is a connection device used to fixedly connect the fiber splicing tray.
