Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
A retention device for retaining bumperless plastic quad flat packs in a frame-shaped socket cover of the type having slots in the base for receiving end portions of leads extending outwardly from the pack, the retention device comprising: a resilient arm attached to a cover wall adjacent each corner and extending into an opening into which a flat pack may be received; and an engaging member attached to and extending perpendicular from an end of said arm and having a flat surface facing in and slanted outwardly, said flat surface adapted to engage a flat surface of a reversed slanted orientation on the flat pack to urge the flat pack outwardly against the restraining force of the end portions in the slots.
Claim 2
Dependent Claim
122 words
A retention device for retaining bumperless plastic quad flat packs in a frame-shaped socket cover of the type having slots in the base for receiving end portions of leads extending outwardly from the pack, the retention device comprising: a resilient arm attached to a cover wall adjacent each corner and extending into an opening into which a flat pack may be received; and an engaging member attached to and extending perpendicular from an end of said arm and having a flat surface facing in and slanted outwardly, said flat surface adapted to engage a flat surface of a reversed slanted orientation on the flat pack to urge the flat pack outwardly against the restraining force of the end portions in the slots.
Claim 3
Dependent Claim
14 words
The retention device of claim 1 wherein said resilient arm includes a curved portion.
Claim 4
Dependent Claim
99 words
An electrical socket cover for electronic devices, said cover comprising: side walls defining a central opening for receiving an electronic device; slots in the base of said side walls for receiving end portions of leads extending outwardly from the electronic device; a resilient arm attached to a side wall at each corner and extending into said central opening; and an engaging member attached to and extending perpendicular from an end of said arm and having a surface facing obliquely outwardly and adapted to engage a surface on the electronic device to urge the device outwardly of said central opening.
Claim 5
Dependent Claim
99 words
An electrical socket cover for electronic devices, said cover comprising: side walls defining a central opening for receiving an electronic device; slots in the base of said side walls for receiving end portions of leads extending outwardly from the electronic device; a resilient arm attached to a side wall at each corner and extending into said central opening; and an engaging member attached to and extending perpendicular from an end of said arm and having a surface facing obliquely outwardly and adapted to engage a surface on the electronic device to urge the device outwardly of said central opening.
