  • Patent number: 10257961
    Abstract: An apparatus and system for a heat sink assembly, and a procedure for forming a heat sink assembly. The heat sink assembly includes a heat sink having a base and fins extending from the base, and a spring clip disposed on the heat sink between the fins. The spring clip includes a first tab that forms a first angle with respect to the base of the heat sink and including a second tab that forms a second angle with respect to the base of the heat sink. The first and second tabs are attached to the circuit board. By virtue thereof, a heat sink attachment to cage is provided that is space-efficient and permits a higher density of cages on a circuit board than do conventional arrangements.
    Type: Grant

  • Patent number: 9215814
    Abstract: Small form-factor pluggable (SFP) ports are often employed in telecommunications hardware to take advantage of their lower profile and to provide connections to other network elements. The use of SFP ports has increased the density of ports possible for a given circuit board size, but this increase has previously meant that individual ports are difficult to access. Also, identification of those ports is frustrated by a lack of free space to place labeling. Example embodiments of the present invention address these issues by placing a divider plate between columns of SFP ports that provides surface area adjacent to the SFP ports for affixing labeling. The divider plate is offset from the SFP ports to allow access when the plate is installed. As a result, hardware employing embodiments of the present invention can achieve a higher density of SFP ports with ease of access by personnel assembling or servicing the hardware.
