Electric connecting structure

摘要

An electric connecting structure includes L-shaped terminals having electric connecting portions and a resin member which contains the electric connecting portions. The L-shaped terminals are assembled to a circuit board so that a mounting direction of electric components to the resin member is substantially parallel to an extending direction of the circuit board. The electric components are mounted to the resin member in a plurality of stages which are stacked in a substantially vertical direction with respect to the extending direction of the circuit board. Mounting planes of the resin member in which the electric components are mounted to the resin member are arranged in a step-like shape so as to be displaced backward in the mounting direction by a unit of the stage in accordance with increasing of a distance from the circuit board.

主权项

1. An electric connecting structure comprising:
a circuit board having a major surface; and L-shaped terminals having horizontal plate portions which extend parallel to the major surface of the circuit board, the horizontal plate portions having electric connecting portions for connecting electric components respectively, the L-shaped terminals being assembled to the circuit board and including a first L-shaped terminal, a second L-shaped terminal, a third L-shaped terminal, and a fourth L-shaped terminal, wherein the L-shaped terminals are arranged such that a horizontal plate portion of the fourth L-shaped terminal is positioned above the horizontal plate portion of the third L-shaped terminal relative to the major surface of the circuit board, the horizontal plate portion of the third L-shaped terminal is positioned above the horizontal plate portion of the second L-shaped terminal relative to the major surface of the circuit board, the horizontal plate portion of the second L-shaped terminal is positioned above the horizontal plate portion of the first L-shaped terminal relative to the major surface of the circuit board, and a length of the horizontal plate portion of the second L-shaped terminal is greater than a length of the horizontal plate portion of the third L-shaped terminal, the electric connecting portions of the first and second L-shaped terminals extend towards and terminate at a first plane, which is perpendicular to the major surface of the circuit board, and the electric connecting portions of the third and fourth L-shaped terminals extend towards and terminate at a second plane, which is in parallel with the first plane and displaced from the first plane by a predetermined distance.
