Abstract: A wedged sliding trough structure includes an insulating body, at least one wedged spring-flake, and at least one pin spring-flake. The insulating body has at least one wedged spring-flake receiving slot and at least one pin spring-flake receiving slot is used for receiving the wedged spring-flake and the pin spring-flake. By adding the spring-flakes in the insulating body, the wedged sliding trough structure of the present invention has the function of preventing static electricity from discharging and has increased strength so it is less likely to be broken.

Abstract: A mounting frame includes a main body, a receiving groove, a plurality of rectangular hole, an engagement groove, a pair of first threaded holes and a pair of second threaded hole. The receiving groove is positioned within the main body, extends to its bottom surface thus a receiving hole is formed. The rectangular holes are separated at an equal distance one another and aligned along a straight line, the rectangular holes are in communication with both the receiving hole and the receiving groove. The engagement groove is positioned within the main body, in vicinity of the front of the metallic main body and extending to the front of the metallic main body thus an opening is formed. Both the pair of first threaded holes and second threaded holes have inner threads positioned on their two ends. The mounting frame is applicable to various computer cases without different dedicated mounting frames.
