Abstract

A method for producing a pair of electrically conductive members assembled into an electrical component assembly provided with a coil. The method includes: forming connection terminal sections provided in the pair of electrically conductive members by arranging them alternately opposite to each other and then performing press punching; and after the press punching, bending the connection terminal sections in the pair of electrically conductive members toward a side departing from the coil into a protruding form.

First claim

What is claimed is:

1. A method for producing a pair of electrically conductive members assembled into an electrical component assembly provided with a coil, the method comprising:
forming connection terminal sections provided in the pair of electrically conductive members by arranging the connection terminal sections facing each other from a side to side direction and alternately opposite to each other with spacing in an up and down direction as arranged on each of the pair of electrically conductive members, and by performing press punching of a metal plate; and
after the press punching of the metal plate, bending the connection terminal sections in the pair of electrically conductive members toward a side departing from the coil into a protruding form.

2. The method according to claim 1 , further comprising:
after the bending into the protruding form, as a resin molding step, including by insert molding the bent portions of the connection terminal sections into a terminal supporting section provided in a bobbin around which the coil is wound,
wherein, by virtue of the resin molding step, the connection terminal sections are formed integrally with the bobbin.

3. The method according to claim 1 , wherein the press punching forms extension pieces from a base to be formed into the connection terminal sections.

4. The method according to claim 3 , wherein the press punching of the connection terminal sections further forms:
tapered shape sections to be formed into winding sections;
first protruding pieces extending transversely to tapered shape sections and to be formed into guide pieces; and
second protruding pieces extending from the tapered shaped sections and transversely from a base portion, which is to be formed into wire connection sections.

5. The method according to claim 4 , wherein:
the guide pieces and the second protruding pieces extend in the up and down direction and in a transverse direction of a linkage section that connects the electrically conductive members; and
the extension pieces extend in right and left directions in a longitudinal direction of the linkage section and transversely to the first and second protruding pieces.

6. The method according to claim 5 , wherein:
a first extension piece of the extension pieces extends from a lower side of a center part of the base to be formed into an extending section, toward a second extension piece side of the extension pieces; and
the second extension piece extends from an upper side of the center part of the base toward the first extension piece side.

7. The method according to claim 6 , wherein the first extension piece and the second extension piece are arranged opposite to each other with spacing in the up and down direction and in such a manner that interference with each other is avoided.

8. The method according to claim 7 , wherein:
the bending is performed on the second protruding pieces of the electrically conductive plates and on the extension pieces.

9. The method according to claim 8 , wherein:
the second protruding pieces are bent from a middle part toward the base such as to rise from a surface of the metal plate to a side along on a first bending line, and then bent toward a lower direction of the metal plate such as to face an upper face of the base.

10. The method according to claim 9 , wherein the extension pieces protrude at right angles relative to the surface of the metal plate, and the bending is performed on the extension pieces along second bending lines toward a left and a right such as to rise from the surface of the metal plate to a near side of the base.

11. The method according to claim 10 , wherein after the bending, at a resin molding step, an insert molding is performed such that bent portions of the extension pieces are formed as resin embedded sections.

12. The method according to claim 11 , further compromising integrally forming a bobbin with the bent portions of the extension pieces.

13. The method according to claim 11 , further comprising, after the insert molding, separating the electrically conductive members from the linkage section.
