Abstract

A terminal connection component including press-fit terminals and terminal metal-fittings. The press-fit terminals have a plate shape in which a taper is disposed at one tip, and the terminal metal-fittings also have a plate shape in which a fitting section is disposed at one end side. The fitting sections of the terminal metal-fittings have a first hole part and a second hole part from the one end in parallel. The tips of the press-fit terminals are press-fitted and are connected to the fitting sections of the terminal metal-fittings, and a portion between the first hole part and the second hole part of the fitting section, which serves as an elastic deformation section, is elastically deformed in a thickness direction of the press-fit terminal and biases the press-fit terminal so that the press-fit terminals are surely press-fitted to the fitting sections of the terminal metal-fittings.

First claim

The invention claimed is:

1. A terminal connection component, comprising:
press-fit terminals; and
terminal metal-fittings,
wherein said press-fit terminals have a plate shape in which a taper is disposed at one tip, and said terminal metal-fittings have a plate shape and have a fitting section at one end,
wherein said fitting sections of said terminal metal-fittings have a first hole part and a second hole part from said one end in parallel,
wherein said first hole part is a rectangular shape,
wherein said second hole part is a rectangular shape, and a central portion of one long side near said first hole part is shifted to an interior of said second hole part so that a length of a central portion of said second hole part is slightly shorter than a thickness of said press-fit terminals, and
wherein said tips of said press-fit terminals are press-fitted to and are connected to said fitting sections of said terminal metal-fittings, and a portion between said first hole part and said second hole part of said fitting section, which serves as an elastic deformation section, is elastically deformed in a thickness direction of said press-fit terminals and biases said press-fit terminal so that said press-fit terminals are surely press-fitted to said fitting sections of said terminal metal-fittings.

2. The terminal connection component according to claim 1 ,
wherein said taper, which is disposed at one tip of said press-fit terminal, has round sections having a curvature at both corner portions in said end portion of said plate, and has a portion that a thickness of side surface portions of said plate decreases toward said end portion.

3. A terminal connection structure between a control unit using said terminal connection component according to claim 1 and a motor,
wherein said control unit comprises a substrate on which at least a control circuit is mounted, and said press-fit terminals stood from said substrate,
wherein said terminal metal-fittings are disposed on said motor, and said motor is connected to one end of said terminal metal-fittings, and
wherein a connection between said control unit and said motor is performed by press-fitting said tips of said press-fit terminals to said fitting-in sections of said terminal metal-fittings.

4. A terminal connection component, comprising:
press-fit terminals, and
terminal metal-fittings,
wherein said press-fit terminals have a first fitting-in section and a second fitting-in section, a tip of said first fitting-in section and a tip of said second fitting-in section are branched from a branch section, said first fitting-in section and said second fitting-in section from said tip to said branch section comprise a guide section and a straight portion, said guide section comprises a first taper section and a second taper section, and a taper ratio of said first taper section is smaller than that of said second taper section,
wherein said terminal metal-fittings have a plate shape, and comprise a fitting section to which said first fitting-in section and said second fitting-in section of said press-fit terminal are press-fitted, at one end,
wherein said fitting section comprises first and second rectangular hole parts which are in parallel disposed in a width direction of said terminal metal-fitting at one end of said terminal metal-fitting, and a bridge section formed between said first and second hole parts, and said first and second hole parts have a short side in a width direction of said terminal metal-fitting and have a long side in a longitudinal direction of said terminal metal-fitting,
wherein a length of said short side of said first and second hole parts is longer than respective widths of said tips of said first and second fitting-in sections in said press-fit terminal, and is shorter than respective widths in said straight portion side of said first and second fitting-in sections,
wherein a length of said long side of said first and second hole parts is longer than respective thicknesses of said first and second fitting-in sections in said press-fit terminal,
wherein a width of said bridge section of said terminal metal-fitting is longer than a space between an inner surface of said first fitting-in section of said press-fit terminal and an inner surface of said second fitting-in section of said press-fit terminal,
wherein a farthest space of said long side between said first hole part and said second hole part is formed shorter than a space between an outer surface in said straight portion of said first fitting-in section of said press-fit terminal and an outer surface in said straight portion of said second fitting-in section of said press-fit terminal,
wherein a connection between said press-fit terminal and said terminal metal-fitting is performed by inserting said tips of said first and second fitting-in sections of said press-fit terminal into said first and second hole parts of said fitting-in section of said terminal metal-fitting, and press-fitting said tips of said first and second fitting-in sections of said press-fit terminal to said first and second hole parts of said fitting-in section of said terminal metal-fitting, and
wherein said press-fitting is achieved by disposing said width direction of said press-fit terminal parallel to said width direction of said terminal metal-fitting at a substantially central portion of said first and second rectangular hole parts of said fitting section, and by pressing said press-fit terminal to said terminal metal-fitting at two portions in first contact regions of both side surfaces of said bridge section and two portions in second contact regions where an inner side-surface of said long side of said first hole part is farthest to that of said second hole part.

5. The terminal connection component according to claim 4 ,
wherein a reference dimension in a width of said bridge section of said terminal metal-fitting is the same as that of a space between an inner surface in said straight portion of said first fitting-in section of said press-fit terminal and an inner surface in said straight portion of said second fitting-in section of said press-fit terminal,
wherein a reference dimension in a farthest space of said long side between said first hole part of said terminal metal-fitting and said second hole part of said terminal metal-fitting is the same as that of a space between an outer surface in said straight portion of said first fitting-in section of said press-fit terminal and an outer surface in said straight portion of said second fitting-in section of said press-fit terminal,
