[0036] After the strain relief 5 is assembled to the first shield part 15, then assembling the spacer 3 to the first shield part 15. The spacer 3 is positioned with the first shield part 15 and located on the printed circuit board 2. The pair of second positioning posts 154 of the first shield part 15 pass through the corresponding two grooves 33 of the spacer 3 along an up-to-down direction to limit a movement of the spacer 3 along a front to rear direction.
[0037] After the spacer 3 is assembled to the first shield part 15, then assembling another printed circuit board 2 and cable 4 together to the first shield part 15 and located on the spacer 3. The printed circuit board 2 is positioned with the first shield part 15 along a front-to-rear direction due to a pair of slots 231 of the printed circuit board 2 cooperated with the pair of second positioning posts 154 of the shield part 15. And, a front end of the cable 4 is supported by the strain relief 5. The ring 42 of the cable 4 has a half portion located in a depressed section 51 of the strain relief 5.
[0038] After another printed circuit board 2 and cable 4 are together assembled to the first shield part 15, then assembling the second shield part 16 to the first shield part 15. Thus, the opening 152 of the first shield part 15 is shielded by second shield part 16 along an up-to-down direction. And, the two printed circuit boards 2 and a spacer 3 are received into the receiving room 11 of the housing 1 and positioned in the housing 1.
[0039] After the second shield part 16 is assembled to the first shield part 15, then assembling the latching member 6 to the pulling member 7 together through following steps. Firstly, the pulling member 7 is disposed above the latching member 6 to make the two through holes 731 of the two actuating sections 73 in alignment with two through holes 621 of the latching member 6 along a transversal direction. The pair of actuating sections 73 of the pulling member 7 are located at two sides of the two hooks 623 of the latching member 6. Secondly, the retaining piece 9 is passed through the through holes 621, 623. Thus, the pulling member 7 is interconnected with the latching member 6 by the retaining piece 9. The pulling member 7 can be rotated to the latching member 6 based on the retaining piece 9 along a clockwise direction.
[0040] Then, assembling the latching member 6 and the pulling member 7 together to an exterior surface of housing 1. The latching member 6 is disposed in the receiving cavity 14. The pulling member 7 is located on the top surface 121 of the body portion 12 of the housing 1. The supporting piece 17 is disposed in the receiving cavity 14 when the pulling member 7 is rotated along a clockwise direction. Two sides of the supporting piece 17 are received into the two recesses 144. The supporting piece 17 is spaced apart with the bottom surface 141 of the receiving cavity 14. Then, the pulling member 7 is rotated along a counter-clockwise direction and attached to the top surface 121 of the body portion 12 of the housing 1. Thus, the curving section 722 of the pulling member 7 is supported by the supporting piece 17. The retaining section 61 of the latching member 6 is engaged with a rear end of the receiving cavity 14. The connecting section 62 of the latching member 6 is disposed above the bottom surface 141 of the receiving cavity 14. The latching portion 63 extends forwardly and is located above the second surface 131 of the mating portion 13 of the housing 1. The latching portion 63 is cantilevered from the retaining portion 61. The two actuating sections 73 of the pulling member 7 is generally located above the connecting section 62 of the latching member 6. A tape 74 is passed through the slit 711 and connected to the pulling member 7. When a rearward pulling force is exerted on a rear end of the pulling member 7 or the tape 74, the latching portion 63 of the latching member 6 will be raised up. When the rearward pulling force is released, the latching portion 63 of the latching member 6 will resume to an original state.
[0041] Finally, assembling the metallic holder 8 to the housing 1 along a rear-to-front direction. The first part 15, the second shield part 16 and the strain relief 5 are bound together by the metallic holder 8. A portion of the pulling member 7 and the latching member 6 is also shielded by the metallic holder 8. And, the pulling member 7 can be moved along a front to rear direction relative to the housing 1 and limited by the metallic holder 8 along a vertical direction. Two tabs 815 are attached to the rear surface of the strain relief 5. Two retaining pieces 9 are respectively passed through the two holes 8151 of the two tabs 815 and received into the two receiving holes 52 of the strain relief 5. Thus, the metallic holder 8 is engaged with the strain relief 5.
[0042] After the above assembling steps, the entire process of assembling of the electrical connector assembly 100 is finished. The electrical connector assembly 100 has a new mating surface to meet higher and higher data transmitting rate. In addition, the electrical connector assembly 1 has a narrow profile and high-density configuration. Thus, the complementary connector (not shown) for mating with the electrical connector assembly 100 will also occupy little space to meet a miniaturization of an internal room of the communication device. On another aspect, a reliable latch mechanism is provided to an exterior surface of the housing. And, an easily and conveniently operating manner between the latching member 6 and the pulling member 7 is achieved.
[0043] It will be understood that the invention may be embodied in other specific forms without departing from the spirit or central characteristics thereof. The present examples and embodiments, therefore, are to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the details given herein.
