Abstract

An electrical cable termination connector (10) includes a front shell (20), a printed circuit board (PCB) (30), a terminal insert (40), a back shell (50), a spacer (60), latches (72), and a boot (70). The PCB has a first edge (34) and a second edge (36) positioned at right angles to each other. First solder pads (33) along the first edge are electrically connected to corresponding second solder pads (35) along the second edge by traces (37) in the PCB. The PCB attaches to a rear of the front shell and terminals in the terminal insert electrically connect to the first solder pads. Stiff, shielded wires (80) of a cable (90) are fixed in the spacer, and conductors (81) of the wires are attached to the second solder pads. This design enables a 90 degree connection between a cable and a mating connector, without sharp bending of the shielded cable.

Claims

1. An electrical connector for terminating a cable with very stiff wires, and for mating with a complementary connector, comprising:

a front shell for coupling with a mating end of the complementary connector;

a plurality of electrical terminals fixed within the front shell, each having a mating end and a mounting end, the mating end being exposed for mating with complementary contacts of the complementary connector; and

a printed circuit board forming a polygon with more than four angles and having a first edge and a second edge, the first and second edges being oriented at a designated, non-zero angle relative to each other, the printed circuit board being electrically connected with the mounting ends of the electrical terminals along its first edge, conductors in the wires of the cable being electrically connected with the printed circuit board along its second edge, and traces within the printed circuit board electrically connecting electrical terminals with corresponding conductors in the wires in the cable.

2. The electrical connector as claimed in claim 1, wherein the angle between the first edge and the second edge is greater than 30 degrees.

3. The electrical connector as claimed in claim 1, wherein the angle between the first edge and the second edge is substantially 90 degrees.

4. The electrical connector as claimed in claim 1, further comprising a dielectric spacer accommodating ends of the wires for holding the wires in designated positions for simplifying connection of the cable to the electrical connector.

5. The electrical connector as claimed in claim 1, further comprising a plurality of first pads along the first edge and a plurality of second pads along the second edge, each first pad being connected with a corresponding second pad via the traces in the printed circuit board, the first pads being for connection with the terminals, and the second pads being for connection with the conductors in the wires.

6. The electrical connector as claimed in claim 5, wherein the traces in the printed circuit board connecting electrical terminals with corresponding conductors of the cable are designed to have substantially a same length.

7. The electrical connector as claimed in claim 1, wherein the front shell is made of a conductive material and the terminals are insert molded into one or more dielectric bodies to make one or more terminal inserts, and the one or more terminal inserts are engagable with the conductive front shell so that the mating ends of the terminals each extend forward into the front shell and the front shell provides protection from electromagnetic interference (EMI) to said mating ends.

8. The electrical connector as claimed in claim 7, further comprising a conductive back shell which is assembled to enclose a portion of the front shell and the PCB, the back shell electrically connecting to the front shell and to the shields of the wires, for providing protection from EMI to the mounting ends of the terminals, to the PCB, and to the bare conductors of the wires attaching to the PCB, the back shell further providing electrical continuity between the front shell, the back shell, and shields of the wires.

9. The electrical connector as claimed in claim 8, further comprising a dielectric boot formed to cover all of the rear shell and an end of the cable.

10. The electrical connector as claimed in claim 9, further comprising a dielectric spacer accommodating ends of the wires for holding the wires in designated positions for simplifying connection of the cable to the electrical connector.

11. The electrical connector as claimed in claim 10, further comprising at least a latch adjacent the back shell and protruding into a mating cavity of the front shell for releasably engaging with a complementary fastening member of a complementary mating connector.

12. A cable connector assembly comprising:

a sleeve defining a lengthwise direction thereof and a cavity therein;

a plurality of terminals disposed in the cavity;

a printed circuit board disposed at a rear portion of the sleeve and extending parallel to said lengthwise direction;

a shielding device enclosing said printed circuit board;

said printed circuit board forming a polygon with more than four angles and defining a first edge mechanically and electrically connected to tails of said terminals, and a second edge mechanically and electrically connected to wires of a cable, both said first edge and said second edge including planar solder pads thereon for soldering with the terminals and the wires of the cable, respectively;

wherein

said first edge extends along said lengthwise direction, said second edge extends perpendicular to said lengthwise direction, and said cable extends along said lengthwise direction without bending.

13. A cable connector assembly comprising:

a sleeve defining a lengthwise direction thereof and a cavity therein;

a plurality of terminals disposed in the, cavity;

a printed circuit board for connecting said terminals and a cable, said circuit board is disposed at a rear portion of the sleeve and extending parallel to said lengthwise direction and forms a polygon with more than four angles and;

a shielding device enclosing said printed circuit board; and

a pair of latches with levers exposed outside of said shielding device while with forward portions extending into the cavity;

wherein

said forward portions include latching structures for latchable engagement with a complementary connector to prevent said complementary connector from being withdrawn from the sleeve in a first direction perpendicular to said lengthwise direction, and said forward portions are moveable to be disengaged from the complementary connector when levers are manually moved in a second direction perpendicular to both said lengthwise direction and said first direction.
