Abstract
Abstract In order to assist the mounting of a printed circuit board to a metallic frame and the soldering of a conductive pattern of the former to the latter, a wire rod of high solderability is bent to conform substantially with the outline of the frame and is disposed at the juncture between the frame and the marginal edge of the circuit board. The circuit board can thus be temporarily fixed to the frame by the resilience of the wire rod and then subjected to dip soldering.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
121 words
In a structure for mounting a printed circuit board formed with a conductive pattern in at least a marginal edge thereof to a frame, wherein abutting portions between the marginal edge of the printed circuit board and the frame are to be soldered; the improvement including means for holding said printed circuit board to said frame prior to soldering of said abutting portions and increasing the mechanical and electrical connection of said abutting portions by the soldering thereof, said means comprising a length of wire bent to conform substantially to the outline of the frame and being located at said abutting portions, said wire being resilient and being easily soldered, whereby said abutting portions inclusive of said wire may be soldered.
Claim 2
Dependent Claim
121 words
In a structure for mounting a printed circuit board formed with a conductive pattern in at least a marginal edge thereof to a frame, wherein abutting portions between the marginal edge of the printed circuit board and the frame are to be soldered; the improvement including means for holding said printed circuit board to said frame prior to soldering of said abutting portions and increasing the mechanical and electrical connection of said abutting portions by the soldering thereof, said means comprising a length of wire bent to conform substantially to the outline of the frame and being located at said abutting portions, said wire being resilient and being easily soldered, whereby said abutting portions inclusive of said wire may be soldered.
Claim 3
Dependent Claim
63 words
A mounting structure for a printed circuit board as defined in claim 1, wherein engaging members are respectively formed at end portions of said wire, while engaging portions adopted to coact said engaging members are provided in said frame, and said engaging members of said wire abut on said engaging portions of said frame so as to hold said wire on said frame.
Claim 4
Dependent Claim
26 words
A mounting structure for a printed circuit board as defined in claim 2, wherein said wire resiliently abuts on said frame owing to its own elasticity.
Claim 5
Dependent Claim
44 words
A mounting structure for a printed circuit board as defined in claim 2, wherein said wire is located on a lower surface of said printed circuit board so as to prevent said printed circuit board from falling out of said frame during the soldering.
Claim 6
Dependent Claim
26 words
A mounting structure for a printed circuit board as defined in claim 1, wherein said wire is a steel wire whose outer peripheral surface is tinned.
