Abstract

An electrical connector is adapted for mounting on a printed circuit board. The connector includes a dielectric housing having at least one row of terminal-receiving passages. A plurality of terminals are received in the passages and include tail portions in a row for connection to appropriate circuit traces on the printed circuit board. The tail portions of some of the terminals in the row are adapted for insertion into holes in the circuit board. The tail portions of other of the terminals in the row are adapted for surface mounting on the circuit board. Tail portions of some of the terminals extend through holes in the tail aligner while enlarged cutout areas in the tail aligner accommodate the surface mount tail portions of the others of the terminals.

Claims

1. An electrical connector for mounting on a printed circuit board, comprising:

a dielectric housing having at least one row of terminal-receiving passages;

a plurality of terminals received in said passages and including tail portions in a row for connection to appropriate circuit traces on the printed circuit board, the tail portions of some of the terminals in said row being adapted for insertion into holes in the circuit board and being the sole means of connecting said some of the terminals to the circuit traces on the board, and the tail portions of other of the terminals in said row being adapted for surface mounting on the circuit board and being the sole means of connecting said other of the terminals to the circuit traces on the board; and

a tail aligner through which the tail portions of the terminals extend, the tail aligner including holes through which the tail portions of said some of the terminals extend, and the tail aligner including enlarged cutout areas adjacent an edge of said tail aligner for accommodating the tail portions of said other of the terminals.

2. The electrical connector of claim 1 wherein the connector is a right-angled connector with a mating portion facing in a direction generally parallel to the printed circuit board.

3. The electrical connector of claim 2 wherein said terminals have right-angled configurations, including contact portions extending in said direction of the mating portion of the connector, and said tail portions extending generally perpendicular to the contact portions.

4. The electrical connector of claim 1 wherein said terminals are stamped and formed from conductive sheet metal material.

5. An electrical connector for mounting on a printed circuit board, comprising:

a right-angled dielectric housing having a mating portion facing in a direction generally parallel to the printed circuit board and at least one row of terminal-receiving passages; and

a plurality of terminals received in said passages, the terminals being stamped and formed from conductive sheet metal material and having right-angled configurations with contact portions extending in said direction of the mating portion of the connector and tail portions extending in a row generally perpendicular to the contact portions for connection to appropriate circuit traces on the printed circuit board, the tail portions of some of the terminals in said row being adapted for insertion into holes in the circuit board and being the sole means of connecting said some of the terminals to the circuit traces on the board, and the tail portions of other of the terminals in said row being adapted for surface mounting on the circuit board and being the sole means of connecting said other of the terminals to the circuit traces on the board.

6. The electrical connector of claim 5, including a tail aligner through which the tail portions of the terminals extend, the tail aligner including holes through which the tail portions of said some of the terminals extend, and the tail aligner including enlarged cutout areas for accommodating the tail portions of said other of the terminals.

7. The electrical connector of claim 6 wherein said enlarged cutout areas of the tail aligner are located at an edge of the tail aligner.

8. An electrical connector for mounting on a printed circuit board, comprising:

a dielectric housing having first and second generally parallel rows of a plurality of terminal-receiving passages, said housing having a mating portion extending forwardly from an elongated flange and generally between said rows of terminal receiving passages; and

first and second pluralities of terminals received in respective ones of said first and second rows of passages, each terminal including a contact portion for mating with a complementary mating connector and a tail portion for connection to appropriate circuit traces on the printed circuit board, the contact portions of said first plurality of terminals being located on a first side of said mating portion and the contact portions of said second plurality of terminals being located on a second side of said mating portion, said second side being opposite said first side, the tail portions of said first plurality of terminals being adapted for insertion into a hole in the circuit board and being the sole means of connecting the terminals to respective circuit traces on the board, and the tail portion of at least one of the second plurality of terminals being adapted for insertion into a hole in the circuit board and being the sole means of connecting the terminals to respective circuit traces on the board, the tail portion of at least one other of the second plurality of terminals being adapted for surface mounting on the board and being the sole means for connecting the other terminal to a circuit trace on the board.

9. The electrical connector of claim 8 wherein the connector is a right-angled connector and said mating portion extends in a direction generally parallel to the printed circuit board.

10. The electrical connector of claim 9 wherein said terminals have right-angled configurations and said tail portions extending generally perpendicular to the contact portions.

11. The electrical connector of claim 8 wherein said terminals are stamped and formed from conductive sheet metal material.

12. The electrical connector of claim 8, including a tail aligner through which the tail portions of the terminals extend, the tail aligner including a hole through which the tail portion of said at least one of said second plurality of terminal extends, and the tail aligner including an enlarged cutout area for accommodating the tail portion of said at least one other of said second plurality of terminals.

13. The electrical connector of claim 12 wherein said enlarged cutout area of the tail aligner is located at an edge of the tail aligner.

14. An electrical connector for mounting on a printed circuit board, comprising:

a dielectric housing having at least one row of terminal-receiving passages;

a plurality of terminals received in said passages and including tail portions for connection to appropriate circuit traces on the printed circuit board, the tail portions of some of the terminals in said row adapted for insertion into holes in the circuit board and arranged in first and second rows such that the first row is staggered from the second row, and being the sole means of connecting said some of the terminals to the circuit traces on the board, and the tail portions of other of the terminals in said row adapted for surface mounting on the circuit board and being the sole means of connecting said other of the terminals to the circuit traces on the board; and

a tail aligner through which the tail portions of the terminals extend, the tail aligner including holes through which the tail portions of said some of the terminals extend, and the tail aligner including enlarged cutout areas adjacent an edge of said tail aligner for accommodating the tail portions of said other of the terminals.

15. The electrical connector of claim 14 wherein the connector is a right-angled connector with a mating portion facing in a direction generally parallel to the printed circuit board.
