Abstract:
1. A surface mount electronic module comprising: a housing having a bottom wall, lateral side walls and a rear wall which cooperate to define a space in said housing having a front opening and an upper opening, said lateral side walls comprising inner surfaces opposite each other and elongated grooves formed in said inner surfaces and extending in a fore and back direction of said housing and in parallel with each other, said bottom wall comprising an inner surface defining said space and a plurality of openings formed in said inner surface of said bottom wall which are spaced apart from one another in a lateral direction of said housing; a lead-frame comprising elongated leads each having a rear portion embedded in said bottom wall of said housing and a forward portion protruding forwardly from said bottom wall and adapted to be soldered on a mounting substrate for surface-mounting of said electronic module on the mounting substrate, said rear portion having a rear end disposed in a corresponding one of said plurality of openings and convex in shape so that a portion thereof protrudes into said space from said corresponding one of said plurality of openings; and an electronic device comprising a printed circuit board having an upper surface, a lower surface, and lateral side edges, and at least one electronic component mounted on said upper surface, said circuit board being fitted in said space in said housing with said lateral side edges of said printed circuit board slidably engaged in said elongated grooves from said front opening of said space of said housing, whereby said rear ends of said leads are elastically pressed by and electrically connected to said printed circuit board.
