  • Publication number: 20110147074
    Abstract: A fixing rack for a telecommunication apparatus allows the easy mounting, heat dissipation and maintenance of the telecommunication apparatus. A frame of the fixing rack is configured with a second hanging portion, a second joint portion and a fixing portion, wherein the fixing portion fixes the fixing rack on the installation surface, the second hanging portion hangs the telecommunication apparatus on the fixing rack with the first hanging portion configured on the back of the telecommunication apparatus, and the second joint portion joins with the first joint portion of the telecommunication apparatus and fixes the telecommunication apparatus on the fixing rack. The second hanging portion and the first hanging portion allow the telecommunication apparatus to be conveniently mounted onto the fixing rack. The fixing rack generates a gap between the telecommunication apparatus and the installation surface and facilitates heat dissipation and maintenance of the telecommunication apparatus.

  • Publication number: 20110147246
    Abstract: A case for communication signal access apparatus comprises a box, a cover, and a hinge portion. The opening surrounding the box is configured with a first leaning part, and the opening surrounding the box is configured with a second leaning part, and the edge surrounding the second leaning part is configured with side dike. The hinge portion is configured on the inner surface on one side of the box and on the inner surface on one side of the cover. When the cover is closed and sealed with the box, the side dike seals the seam from the closing of the first leaning part with the second leaning part. Thus, the case for communication signal access apparatus according to the present invention employs the side dike to separate water or dust from introducing into the case through the seam between the first leaning part and the second leaning part.
