Referring to FIGS. 1 to 4, a dual orientation connector assembly 100 for mating with a complementary connector (not shown) in two directions comprises an insulative housing 1, a printed circuit board (PCB) 2 received in the insulative housing 1, a mating member 3 soldered on the PCB 2, a pair of magnetic components 4 disposed in the insulative housing 1, a cable 5 extended from an end of the insulative housing 1, an LED (light emitting diode) 6 soldered on another end of the insulative housing 1, and a metal member 7 mounted on one end of the cable 5.

The insulative housing 1 is generally cylindrical. The insulative housing 1 comprises a first housing part 11 and a second housing part 12 mounted with the first housing part 11. The first housing part 11 comprises an opening 13 for being extended by the mating member 3 out of the insulative housing 1. A tail end of the first housing part 11 has an annular portion 14. Referring to FIG. 5, the insulative housing 1 comprises a light area 15. A wall thickness of the light area 15 is thinner than the wall thickness of the other portion of the insulative housing 1 to make the light through the light area 15 more visible or brighter. The insulative housing 1 comprises a side wall.

The PCB 2 comprises an upper surface 21 and an opposite lower surface 22. The PCB 2 comprises a plurality of conductive pads 23 disposed on the lower surface 22 of the PCB 2. The conductive pads 23 comprise a signal pad 231 for transmitting control signal and a power pad 232 for transmitting power signal. A size of the power pad 232 is greater than the size of the signal pad 231. The end of the PCB 2 closed to the cable 5 recesses inwardly to form a holding slot 24. Another end of the PCB 2 comprises a hole 25 for mounting the LED 6.

The mating member 3 is mounted on the upper surface 22 of the PCB 2. The mating member 3 comprises a mounting portion 31 received in the insulative housing 1 and a mating portion 32 extending out of the side wall of the insulative housing 1 for mating with the mating connector. The mating portion 32 comprises a first surface 33 and an opposite second surface 34. The first surface 33 and the second surface 34 comprise same number of terminals 35.

The pair of magnetic components 4 are mounted on the upper surface 21 of the PCB 2 and disposed on two sides of the mounting portion 31 of the mating member 3, respectively. The magnetic components 4 provide a retaining force when the dual orientation connector assembly 100 is mated with the mating connector.

The cable 5 is soldered on the lower surface 22 of the PCB 2. The cable 5 comprises an outer layer 51, a braid layer 52 enclosed in the outer layer 51, a first insulative layer 53 enclosed in the braid layer 52, a first conductor 54 enclosed in the first insulative layer 53, a second insulative layer 55 enclosed in the first conductor 54, and a second conductor 56 enclosed in the second insulative layer 55. The first conductor 54 of the cable 5 is soldered with the power pad 232, and the second conductor 56 is soldered with the signal pad 231. The first insulative layer 53 of the cable 5 is held by the holding slot 24 so that the cable 5 can be soldered with the conductive pads 23 stably.

The LED 6 comprises a lamp 61 and a connecting portion 62 electrically connected with the PCB 2. The lamp 61 comprises a first face 611, an opposite second face 612, and a side face 613 connecting the first face 611 and the second face 612. The connecting portion 62 extends from the second face 612 of the lamp 61 and bends into the hole 25 of the PCB 2. The connecting portion 62 is fixed with the PCB 2 by soldering. The first face 611 recesses toward the second face 612 to form a taper surface 614. The taper surface 614 has a coating layer made of reflective material to increase the efficiency of reflection. The light revealed by the lamp 61 emits from the side face 613 after being reflected by the taper surface 614. The taper surface 614 is a conical surface so that the light can form a light ring after being reflected. An angle of a center line and a generatrix of the taper surface 614 is about 45° so that the light can be emitted vertically after being emitted horizontally to the taper surface 614. The light emitted from the side face 613 passes through the light area 15 of the insulative housing 1. A height of the taper surface 614 is equal to the width of the light area 15. A distance from a top of the taper surface 614 to the first face 611 is shorter than the distance from the second face 612 to the first face 611.

The metal member 7 is mounted on the end of the cable 5. The metal member 7 comprises a crimping portion 71 mounted on the braid layer 52 of the cable 5 and a holding portion 72 extending from the crimping portion 71 and making the first insulative layer 53 hold onto the PCB 2.

When assembling the dual orientation connector assembly 100, the mating member 3 is soldered on the PCB 2 firstly. The cable 5 is then peeled and the braid layer 52 turned over onto the outer layer 51 to expose the first insulative layer 53, the first conductor 54, the second insulative layer 55, and the second conductor 56. The cable 5 is put on the end of the PCB 2. Then the first insulative layer 53 is held in the holding slot 24 of the PCB 2. The second conductor 56 is soldered to the signal pad 231 on the lower surface 22 of the PCB 2, and the first conductor 54 is soldered to the power pad 232. The crimping portion 71 of the metal member 7 is placed on the braid layer 52, and the holding portion 72 is placed on the upper surface 21 of the PCB 2 and holds the first insulative layer 53. The crimping portion 71 is bent to form a ring to enclose the braid layer 52 of the cable 5. The magnetic components 4 are placed on both sides of the mating member 3, respectively, and double-sided adhesives are used to fix the magnetic components 4. The connecting portion 62 of the LED 6 is inserted into the hole 25 of the PCB 2. The LED 6 is fixed by soldering. The annular portion 14 of the first housing part 11 is set from the cable 5. Lifting the first housing part 11 to make the mating member 3 extend out of the first housing part 11 from the opening 13. The first housing part 11 and the second housing part 12 are assembled together to receive the PCB 2. The first housing part 11 and the second housing part 12 are fixed by the technology of ultrasonic fusion-bonding. Peptide compounds can be filled into the insulative housing 1 to make the light sent out by the LED 6 evenly.
