Abstract
Abstract An outdoor wireless base station with a circuit pack within a housing. A printed circuit board of the pack has opposite edges formed with spaced projections and the housing has spaced guide elements to receive the projections for mounting purposes. To mount the circuit pack, the circuit board is moved to pass the projections laterally between the guide elements to enable the projections to become aligned with and then to move along the guide elements.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
132 words
A wireless base station for outside use comprising a housing having mounting positions for receiving two circuit packs within the housing, each circuit pack having a printed circuit board with opposite edges each formed with spaced apart projections and the housing at the associated mounting position provided with spaced apart guide elements for slidably receiving associated projections at the opposite edges of the printed circuit board, the guide elements being spaced apart to allow for lateral movement of the projections between the guide elements to permit interengagement of the projections with the guide elements and the guiding of the printed circuit board into its mounting position and wherein the circuit packs have intermateable connectors for electrically connecting one circuit pack with the other when the circuit packs are in their mounting positions.
