Abstract

A system is provided for varying the capacitive coupling between adjacent terminals in an electrical connector. A connector housing includes at least a pair of adjacent terminal-receiving passages. At least a pair of terminals are insertable into the passages. Each terminal includes a contact end and a terminating end. A pair of generally parallel, laterally spaced arms extend in a given direction between the contact and terminating ends. One end of one of the arms is joined to the contact end, and one end of the other of the arms is joined to the terminating end. An irregularly shaped portion joins the ends of opposite end of the arms. Therefore, the pair of terminals can be inserted into the passages as mirror images of each other to maximize capacitive coupling between the terminals. Alternatively, the pair of terminals alternately can be inserted into the passages inverted relative to each other to transversely misalign the irregularly shaped portions and, thereby, reduce the capacitive coupling between the terminals.

Claims

1. A system for varying the capacitive coupling between the adjacent terminals in an electrical connector, comprising:

a dielectric housing having at least a pair of adjacent terminal-receiving passages; and

at least a pair of terminals insertable into said passages, each terminal including

a contact end,

a terminating end,

a pair of generally parallel laterally spaced arms extending in a given direction between said ends,

one end of one of said arms being joined to said contact end,

one end of the other of said arms being joined to said terminating end, and

an S-shaped portion joining the ends of said arms opposite said one ends,

whereby the pair of terminals can be inserted into the passages as mirror images of each other transversely of said given direction to maximize capacitive coupling between the terminals, and the pair of terminals alternately can be inserted into the passages inverted relative to each other to transversely misalign said S-shaped portions and, thereby, reduce the capacitive coupling between the terminals.

2. The system of claim 1 wherein the terminating end of each of said terminals includes a base portion extending transversely of said given direction and to which said one end of the other of said arms is joined.

3. The system of claim 2 wherein said terminating end comprises a tail portion extending from the base portion.

4. The system of claim 3 wherein said base portion is elongated sufficiently to provide plural locations from which the tail portion can extend.

5. The system of claim 1 wherein said contact end of each terminal comprises a contact blade.

6. The system of claim 1 wherein said pair of arms of the pair of terminals substantially overlap each other transversely of said given direction when the terminals are inverted relative to each other.

7. The system of claim 1, including a plurality of pairs of said terminal-receiving passages for receiving a corresponding plurality of pairs of said terminals, whereby at least one pair of terminals can be oriented as mirror images of each other and at least one other pair of terminals can be oriented as inverted relative to each other.

8. A system for varying the capacitive coupling between the adjacent terminals in an electrical connector, comprising:

a dielectric housing having at least a pair of adjacent terminal-receiving passages; and

at least a pair of terminals insertable into said passages, each terminal including

a contact end,

a terminating end,

a pair of generally parallel laterally spaced arms extending in a given direction between said ends,

one end of one of said arms being joined to said contact end,

one end of the other of said arms being joined to said terminating end,

an irregularly shaped portion joining the ends of said arms opposite said one ends, and

the terminating end having a centerline extending in the given direction, each arm located an equal distance from said centerline, the contact end extending in said given direction parallel to the centerline and the irregularly shaped portion being symmetrical about a line beginning at said one end of said one arm and ending at said one end of said other arm so that the contact end moves along said centerline,

whereby the pair of terminals can be inserted into the passages as mirror images of each other transversely of said given direction to maximize capacitive coupling between the terminals, and the pair of terminals alternately can be inserted into the passages inverted relative to each other to transversely misalign said irregularly shaped portions and, thereby, reduce the capacitive coupling between the terminals.

9. The system of claim 8 wherein the terminating end of each of said terminals includes abase portion extending transversely of said given direction and to which said one end of the other of said arms is joined.

10. The system of claim 9 wherein said terminating end comprises a tail portion extending from the base portion.

11. The system of claim 10 wherein said base portion is elongated sufficiently to provide plural locations from which the tail portion can extend.

12. The system of claim 8 wherein said contact end of each terminal comprises a contact blade.

13. The system of claim 8 wherein said pair of arms of the pair of terminals substantially overlap each other transversely of said given direction when the terminals are inverted relative to each other.

14. The system of claim 8, including a plurality of pairs of said terminal receiving passages for receiving a corresponding plurality of pairs of said terminals, whereby at least one pair of terminals can be oriented as mirror images of each other and at least one other pair of terminals can be oriented as inverted relative to each other.

15. The system of claim 8, wherein the pair of arms are generally the same length.
