Abstract
Abstract A switching coax jack is disclosed having a housing which contains first and second spaced apart electrical conductors. At least a first port is formed in the jack housing and sized to receive a jack plug which is inserted through the port into the housing with a jack plug in electrical communication with the first conductor. A switch assembly contains a normal spring for connecting the first and second conductors. The spring is resiliently deformable away from electrical engagement with the first and second conductors. As the spring deforms, it assumes a deformed shape. The switch assembly includes a support surface opposing the normal spring and having a shape complimentary to the deformed shape of the normal spring.

Total Claims: 14
Claim 1
Independent Claim
336 words
A switch coax jack comprising: a jack housing; first and second spaced apart electrical signal conducting means disposed within said housing; at least a first port formed in said jack housing and sized to receive a jack plug to be inserted through said port and into said housing with said plug in electrical communication with said first electrical signal conducting means; a switch assembly for electrically connecting said first and second conducting means when a plug is absent from said first port and for breaking electrical connection between said first and second conducting means when the plug is inserted into said first port; said switch assembly including a normal spring of electrically material with said normal spring having a first portion biased into releasable electrical contact with said first conducting means and a second portion in electrical contact with said second conducting means; said switch assembly further including urging means for urging said first portion away from said first conducting means in response to an insertion of a plug into said first port with said urging means applying an urging force on said first portion at a first predetermined location; said switch assembly including means for retaining said normal spring in said jack housing with said normal spring having a portion held in a fixed location; said normal spring first portion resiliently deformable from said fixed location to said predetermined location in response to said urging force, said first portion presenting a spring surface of predetermined shape as said first portion is deformed in response to an urging force in an absence of restraints opposing said first portion assuming said predetermined shape; and said switch assembly including a support surface opposing said first portion as said first portion is deformed, said support surface selected to be complementary to said predetermined shape and positioned to oppose and abut said spring surface as said spring surface is urged to said predetermined shape with said support surface positioned to complementarily mate with said spring surface in said predetermined shape.
