EMI protection housing and connector seal for circuit packs installed in electronics systems

摘要

A circuit pack housing for providing EMI protection for a circuit pack which may be inserted into an electronics system such as a telecommunications base station cabinet. The circuit pack housing has a single piece plastic design which surrounds the enclosed circuit pack. The internal walls of the circuit pack housing are metalized, and the inner surface of the housing comprises one or more grounding tabs with metalized surfaces. The metalized plastic circuit pack housing also comprises two opposite living hinges and a self latching mechanism, such that when the circuit pack is placed inside the housing and the housing is closed on itself (i.e., with use of the living hinges), the circuit pack is sealed within the housing and protected from EMI thereby. Moreover, the housing may include protruding flexible tabs at the ends thereof, which advantageously seals around the connector which energizes the circuit pack.
