Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
155 words
A device for connecting electrical circuits comprising a cartridge type tape player, a plug body having a lateral block thereon, a pair of metal sensors each having U-shaped ends on one end of said plug body and extending therethrough, contacting members integral with said sensor U-shaped ends and extending laterally of said plug body, a plurality of pin contacts extending through and from said block, a jack body, resilient contact fingers extending through said jack body and each positioned for detachably engaging one of said contacting members and pin contacts when said plug body is engaged with said jack body providing an electrical connection between said contact fingers and said contacting members and pin contacts and a cover case of a U-shape having ends detachably engaging said jack body, enclosing said contact fingers and an opening for receiving therethrough said contacting members and pin contacts when said plug body is plugged into said jack body.
Claim 2
Independent Claim
155 words
A device for connecting electrical circuits comprising a cartridge type tape player, a plug body having a lateral block thereon, a pair of metal sensors each having U-shaped ends on one end of said plug body and extending therethrough, contacting members integral with said sensor U-shaped ends and extending laterally of said plug body, a plurality of pin contacts extending through and from said block, a jack body, resilient contact fingers extending through said jack body and each positioned for detachably engaging one of said contacting members and pin contacts when said plug body is engaged with said jack body providing an electrical connection between said contact fingers and said contacting members and pin contacts and a cover case of a U-shape having ends detachably engaging said jack body, enclosing said contact fingers and an opening for receiving therethrough said contacting members and pin contacts when said plug body is plugged into said jack body.
Claim 3
Dependent Claim
54 words
A device for connecting electrical circuits as claimed in claim 1 wherein said plug body is mounted on the tape player chassis for utilizing said sensors as the sensing member for the electromagnetic tape of the tape cartridge and said jack body is mounted on said tape cartridge facing an opening in said cartridge.
