Abstract

An electrical connector terminal has an elongated wire board mounting portion that fits axially in a terminal opening in a wiring board. An elongated, generally planar wire connecting portion has an axis in common with that of the mounting portion and is formed to connect with an outside lead. A shoulder portion between the mounting portion and the wire connecting portion has a first section extending from a base of the wire connecting portion and normally of the wire connecting portion, wherein the terminal is held stable when the first section is restrained by a part outside the plane of the wire connecting portion. A second section of the shoulder portion diverges from an end of the first section and extends parallel to the wire connecting portion. An end of the second section provides a desired coupling with a confronting end of a shoulder portion of a like connector terminal.

Claims

1. An electrical connector terminal, comprising:

an elongated wire board mounting portion having an axis, wherein the mounting portion is formed to fit axially in a terminal opening in a wire board;

an elongated generally planar wire connecting portion having an axis the same as the axis of the mounting portion and formed to connect electrically with an outside wire lead; and

a shoulder portion formed between the mounting portion and the wire connecting portion, wherein the shoulder portion has a first section that extends from a base of the wire connecting portion in a direction normal to the wire connecting portion so that the terminal will be held stably relative to the wire board when the first section of the shoulder portion is restrained by an outside part at a position outside the plane of the wire connecting portion;

the shoulder portion has a second section that diverges from an end of the first section farther from the wire connecting portion, and the second section extends in a direction that is parallel to the wire connecting portion; and

an end of the second section of the shoulder portion is dimensioned and arranged to provide a desired amount of coupling in association with a confronting end of a second section of a shoulder portion of a like connector terminal.

2. A terminal according to claim 1, wherein said mounting portion, said wire-connecting portion and said shoulder portion are formed integrally from a sheet of metallic material.

3. A terminal according to claim 1, wherein said wire-connecting portion has an insulation displacement connector (IDC) configuration.

4. A terminal according to claim 1, wherein said mounting portion has two opposed curvilinear sections forming an elongated, open needle-eye configuration about the axis of the mounting portion.

5. An electrical connector terminal arrangement, comprising:

a wire board; and

at least a first connector terminal and a second connector terminal mounted on the wire board, wherein each terminal includes;

an elongated wire board mounting portion having an axis, wherein the mounting portion is formed to fit axially in a terminal opening in the wire board;

a wire connecting portion formed to lie in a first plane which coincides with the axis of the mounting portion, and the connecting portion is formed to connect electrically with an outside wire lead; and

a shoulder portion joined between the mounting portion and the wire connecting portion, wherein the shoulder portion has a first section that extends in a second plane parallel to the axis of said mounting portion and which is normal to the first plane of the wire connecting portion so that the terminal will be held stably relative to the wire board when the first section of the shoulder portion is restrained by an outside part at a position outside the first plane of the wire connecting portion;

the shoulder portion has a second section that diverges from the first section and extends in a third plane that is parallel to the first plane of the wire connecting portion, and

an end of the second section of the shoulder portion of the first terminal is aligned with and spaced from an end of the second section of the shoulder portion of the second terminal to obtain a desired coupling between the first and the second connector terminals.

6. An electrical connector terminal arrangement according to claim 5, wherein said mounting portion, said wire-connecting portion and said shoulder portion are formed integrally from a sheet of metallic material.

7. A terminal arrangement according to claim 5, wherein said wire-connecting portion has an insulation displacement connector (IDC) configuration.

8. An electrical connector terminal arrangement according to claim 5, wherein said mounting portion has two opposed curvilinear sections forming an elongated, open needle-eye configuration about the axis of the mounting portion.

9. An electrical connector terminal block, comprising:

a housing;

a wire board supported in the housing;

a base wall supported in the housing in the vicinity of the wire board;

a first connector terminal and a second connector terminal mounted on the wire board, wherein each of the first and the second connector terminals includes;

an elongated wire board mounting portion having an axis, wherein the mounting portion is formed to fit axially in a terminal opening in the wire board;

an elongated generally planar wire connecting portion having an axis the same as the axis of the mounting portion and formed to connect electrically with an outside wire lead; and

a shoulder portion formed between the mounting portion and the wire connecting portion, wherein the shoulder portion has a first section that extends from a base of the wire connecting portion in a direction normal to the wire connecting portion, so that the first and the second connector terminals are held stable relative to the wire board when the first section of the shoulder portion of each terminal is restrained by said base wall at a position outside the plane of the wire connecting portion of each terminal;

the shoulder portion of each terminal has a second section that diverges from an end of the first section farther from the wire connecting portion, and the second section extends in a direction that is parallel to the wire connecting portion; and

an end of the second section of the shoulder portion of the first terminal is aligned with and spaced from an end of the second section of the shoulder portion of the second terminal in such a manner as to obtain a desired coupling between the first and the second connector terminals.

10. An electrical connector terminal block according to claim 9, including a third connector terminal mounted on the wire board and aligned between the first and the second connector terminals.

11. An electrical connector terminal block according to claim 10, wherein the third connector terminal also has said wire board mounting portion, said wire connecting portion, and said shoulder portion.

12. An electrical connector terminal block according to claim 9, including terminal wire guide posts formed on said housing, wherein the guide posts have channels for receiving the wire connecting portions of the first and the second connector terminals.

13. An electrical connector terminal block according to claim 11, including terminal wire guide posts formed on said housing, wherein the guide posts have channels for receiving the wire connecting portions of the first, the second, and the third connector terminals, and the shoulder portion of the third connector terminal is restrained by a bottom surface of the terminal wire guide posts.
