Abstract

A harness connector having a header assembly that includes a header housing that extends between a plug end and a mounting end. The header housing holds header contacts. Optionally, the header housing may be mounted to a printed circuit board at the mounting end with the header contacts being electrically connected to the printed circuit board. One or more plug assemblies are received in the plug end of the header housing along a plug axis. The plug assembly includes a plug housing holding receptacle terminals. The receptacle terminals extend along terminal axes parallel to the plug axis between mating ends and terminating ends. The mating ends are mated with corresponding header contacts. The terminating ends have insulation displacement contacts configured to receive, and be electrically connected to, corresponding wires. The wires extend from the insulation displacement contacts along wire axes that are generally perpendicular to the terminal axes.

Claims

1. A harness connector comprising:

a header assembly including a header housing extending between a plug end and a mounting end, the header housing includes alignment ribs extending from the mounting end, the header housing holding header contacts, wherein each header contact is stamped into an L-shape to include a pin and a tail extending generally perpendicular to the pin, the stamped header contacts each include first and second sides and shear edges extending between the first and second sides, a shear edge along the tail being configured to be surface mounted to a printed circuit board, the alignment ribs engaging the other shear edge of each tail to align the tails for surface mounting to the printed circuit board; and

a plug assembly received in the plug end of the header housing along a plug axis, the plug assembly including a plug housing holding receptacle terminals, the receptacle terminals extending along and receiving the header contacts along terminal axes, the terminal axes being generally parallel to the plug axis, the mating ends being mated with corresponding header contacts, the terminating ends having insulation displacement contacts configured to receive, and be electrically connected to, corresponding wires, the wires received in the insulation displacement contacts along wire axes that are generally perpendicular to the plug axis and the terminal axes, and the wires extending from the insulation displacement contacts along the wire axes.

2. The harness connector of claim 1, wherein the insulation displacement contacts define slots configured to receive corresponding wires.

3. The harness connector of claim 1, wherein each terminating end has a first insulation displacement contact defining a first slot and a second insulation displacement contact defining a second slot, the first and second slots being aligned along the wire axis of the wire terminated to the corresponding receptacle terminal, the wire being received in both the first and second slots of the corresponding receptacle terminal.

4. The harness connector of claim 1, wherein the plug housing includes a front and a rear extending between an outer end and an inner end, the inner end being plugged into the header housing, the front and rear extending parallel to the terminal axes, the plug housing having a plurality of open ended channels in the front and rear at the outer end, the insulation displacement contacts receiving the wires through the open ended channels, the wires extending from the front.

5. The harness connector of claim 1, wherein the plug housing includes a front and a rear extending between an outer end and an inner end, the inner end being plugged into the header housing, the front and rear extending parallel to the terminal axes, the wire axes being oriented generally perpendicular to the front and the rear.

6. The harness connector of claim 1, further comprising a second plug assembly received in the plug end of the header housing.

7. The harness connector of claim 1, further comprising a second plug assembly received in the plug end of the header housing in a staggered relationship, the second plug assembly being positioned further from the mounting end of the header housing than the other plug assembly, the wires extending from the second plug assembly extending over the other plug assembly.

8. The harness connector of claim 1, wherein the plug assembly holds the receptacle terminals in a staggered relationship with at least one of the receptacle terminals being positioned further from the mounting end than at least one other receptacle terminal.

9. The harness connector of claim 1, wherein the receptacle terminals include a first receptacle terminal and a second receptacle terminal that is not identical to the first receptacle terminal.

10. The harness connector of claim 1, wherein the header housing includes epoxy pads extending from the mounting end, epoxy being applied to the epoxy pads to secure the header housing to a printed circuit board.

11. The harness connector of claim 1, wherein the receptacle terminals include sockets at the mating ends, the header contacts being received in the sockets, the receptacle terminals including mating fingers extending into the sockets to engage corresponding header contacts.

12. The harness connector of claim 1, wherein the receptacle terminals include sockets at the mating ends, the pins of the header contacts being received in the sockets, the receptacle terminals including mating fingers extending into the sockets to engage the header contacts, the receptacle terminals being oriented in the plug housing such that the mating fingers engage one of the first side or the second side and do not engage the shear edges.

13. The harness connector of claim 1, wherein the plug assembly includes an outer end, a space being defined along a side of the header assembly and plug assembly bounded at a bottom by a plane extending from the mounting end of the header assembly and bounded at a top by a plane extending from the outer end of the plug assembly, the wires extending from the plug assembly within the space between the plane extending from the outer end of the plug assembly and the plane extending from the mounting end of the header assembly.

14. A harness connector comprising:

a header assembly including a header housing extending between a plug end and a mounting end, the header housing having a first plug chamber and a second plug chamber extending between the plug end and the mounting end, the header housing holding header contacts in the first and second plug chambers;

a first plug assembly received in the first plug chamber through the plug end of the header housing along a plug axis; and

a second plug assembly received in the second plug chamber through the plug end of the header housing along a plug axis;

the first and second plug assemblies each including a plug housing holding receptacle terminals, the receptacle terminals extending along terminal axes parallel to the corresponding plug axis between mating ends and terminating ends, the mating ends being mated with corresponding header contacts, the terminating ends having insulation displacement contacts configured to receive, and be electrically connected to, corresponding wires, the wires being received in, and extending from, the insulation displacement contacts along wire axes that are generally perpendicular to the plug axis and the terminal axes;

wherein the first and second plug assemblies are received in the first and second plug chambers in a staggered relationship with the second plug assembly being positioned further from the mounting end of the header housing than the first plug assembly, the first and second plug assemblies being received in the first and second plug chambers such that the second plug assembly does not pass vertically over any portion of the first plug assembly and such that the first plug assembly does not pass vertically over any portion of the second plug assembly, the wires extending from the second plug assembly extending over the plug housing of the first plug assembly; and

wherein the plug housings each include a front and a rear extending between an outer end and an inner end, the inner end being plugged into the header housing, the front and rear extending parallel to the terminal axes, the wires extending from the front of the plug housing of the first plug assembly, the wires extending from the front of the plug housing of the second plug assembly over the outer end of the plug housing of the first plug assembly.
