Abstract
Abstract An easily assembled battery contact arrangement for a radio is formed of mating parts which can be assembled without tools and fitted into a mating receptacle in the radio. This arrangement includes an opening which accepts the terminal of a chargeable battery, and provides electrical connection to an external projection which permits the battery to be charged while the battery is in the radio.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
253 words
In a battery powered radio receiver or the like that requires a battery to be charged while said battery is positioned in said radio receiver or the like, an improved battery contact arrangement for said radio receiver or the like comprising: a. a metallic member having an opening therethrough; b. an insulating member positioned adjacent said metallic member, said insulating member having a first opening therethrough substantially in alignment with said opening in said metallic member, and said insulating member further having an enlarged opening adjacent to said first opening and located on the side of said first opening away from said metallic member; c. a metallic contact positioned in said enlarged opening in said insulating member in the vicinity of said first opening in said insulating member, said metallic contact being larger than said first opening in said insulating member for retention in said enlarged opening in said insulating member; d. a metallic spring positioned in said enlarged opening in said insulating member against said metallic contact; e. and a metallic charging projection having a contact portion for engaging an external battery charging terminal and having a base portion, said metallic charging projection being positioned with said base portion in contact with said insulating member on the side thereof away from said metallic member and with said contact portion in contact with said spring, and said metallic charging projection holding said spring in said enlarged opening in said insulating member between said metallic contact and said contact portion of said charging projection.
Claim 2
Dependent Claim
253 words
In a battery powered radio receiver or the like that requires a battery to be charged while said battery is positioned in said radio receiver or the like, an improved battery contact arrangement for said radio receiver or the like comprising: a. a metallic member having an opening therethrough; b. an insulating member positioned adjacent said metallic member, said insulating member having a first opening therethrough substantially in alignment with said opening in said metallic member, and said insulating member further having an enlarged opening adjacent to said first opening and located on the side of said first opening away from said metallic member; c. a metallic contact positioned in said enlarged opening in said insulating member in the vicinity of said first opening in said insulating member, said metallic contact being larger than said first opening in said insulating member for retention in said enlarged opening in said insulating member; d. a metallic spring positioned in said enlarged opening in said insulating member against said metallic contact; e. and a metallic charging projection having a contact portion for engaging an external battery charging terminal and having a base portion, said metallic charging projection being positioned with said base portion in contact with said insulating member on the side thereof away from said metallic member and with said contact portion in contact with said spring, and said metallic charging projection holding said spring in said enlarged opening in said insulating member between said metallic contact and said contact portion of said charging projection.
Claim 3
Dependent Claim
81 words
The battery contact arrangement of claim 1 wherein said opening in said metallic member and said opening in said insulating member are aligned and large enough to permit passage of the terminal of a chargeable battery to engage said metallic contact for charging, and wherein said metallic contact is spaced from said metallic member to prevent engagement thereof by the terminal of a nonchargeable battery, whereby both batteries can engage said metallic member for operating said radio receiver or the like.
