Abstract
An electronic equipment comprises key input means having a plurality of key input areas, a frame member for sandwiching a metal plate therein, and printed circuit means having a key input circuit adapted to be closed by a depression force from the key input area and having an electronic part connected thereto. The key input means covers an upper surface of the frame member. The frame member has convey means for conveying the depression force from the key input area to the printed circuit means.
Claims6
Electronic equipment comprising:
- a frame body made of high molecular material;
- a metal plate, having substantially the same peripheral shape as said frame body, insert-molded into said frame body to be sandwiched therein thereby to comprise a frame member having upper and lower surfaces, said metal plate being thin and being formed with a plurality of movable contacts divided into a plurality of groups and with a plurality of connection terminals for interconnecting said plurality of groups;
- means having a plurality of key inputting areas for covering said upper surface of said frame member
- printed circuit means having a key input circuit adapted to be closed by a depression force from said key inputting areas;
- and
- electronic parts connected to said printed circuit means;
- at least a portion of said connection terminals being severed electrically to isolate adjacent groups of said contacts, and at least a portion of said connection terminals being severed and bent continuously to make electrical connection with said printed circuit means;
- said frame member further having convey means for conveying the depression force from said key inputting area to said printed circuit means.

Electronic equipment comprising:
- a frame body made of high molecular material and having upper and lower surfaces;
- a metal plate having substantially the same peripheral shape as and being integrally sandwiched within said frame body between said upper and lower surfaces thereby to comprise a frame member;
- means having a plurality of key inputting areas covering said upper surface of said frame member;
- printed circuit means having a key input circuit adapted to be closed by application of a depression force to said key inputting areas;
- and
- electronic components connected to said key input circuit actuated by closure thereof;
- said frame member further including conveying means for conveying a depression force from said key inputting areas to said printed circuit means;
- said metal plate including a plurality of projecting portions projecting from said frame body and supported by a mold support during the insert-molding operation;
- at least some of said projecting portions being severed electrically to isolate adjacent parts of said metal plate and at least some of said projecting portions being severed and bent continuously to make electrical connection with said printed circuit means.
6 more elements
Electronic equipment having a key input function comprising:
- printed circuit means having an open key input circuit;
- and
- a frame member having means for closing said key input circuit, said frame member comprising a frame body made of insulative high molecular material and a metal plate insert-molded within said frame body, at least one portion of said metal plate defining said closing means and which may be supported directly by a mold support during the insert-molding operation;
- said frame member further comprising a plurality of projections including a portion of said metal plate, other than said closing means, formed by being directly supported by a mold support during the insert-molding operation;
- at least some of said projections being severed electrically to isolate adjacent parts of said metal plate and at least some of said projections being severed and bent continuously to make contact with said printed circuit means.
