## Background
FIELD OF THE INVENTION
The present invention generally relates to connectors suitable for transmitting data, more specifically to input/output (I/O) connectors with high-density configuration and high data transmitting rate.
DESCRIPTION OF PRIOR ART
One aspect that has been relatively constant in recent communication development is a desire to increase performance. Similarly, there has been constant desire to make things more compact (e.g., to increase density). For I/O connectors using in data communication, these desires create somewhat of a problem. Using higher frequencies (which are helpful to increase data rates) requires good electrical separation between signal terminals in a connector (so as to minimize cross-talk, for example). Making the connector smaller (e.g., making the terminal arrangement more dense), however, brings the terminals closer together and tends to decrease the electrical separation, which may lead to signal degradation.
In addition to the desire at increasing performance, there is also a desire to improve manufacturing. For example, as signaling frequencies increase, the tolerance of the locations of terminals, as well as their physical characteristics, become more important. Therefore, improvements to a connector design that would facilitate manufacturing while still providing a dense, high-performance connector would be appreciated.
Additionally, there is a desire to increase the density of I/O plug-style connectors and this is difficult to do without increasing the width of the connectors. Increasing the width of the plug connectors leads to difficulty in fitting the plug into standard width routers and/or servers, and would require a user to purchase non-standard equipment to accommodate the wider plug converters. As with any connector, it is desirable to provide a reliable latching mechanism to latch the plug connector to an external housing to maintain the mated plug and receptacle connectors together modifying the size and/or configuration the connector housing may result in a poor support for a latching mechanism. Latching mechanisms need to be supported reliably on connector housings in order to effect multiple mating cycles. Accordingly, certain individuals would appreciate a higher density connector that does not have increased width dimensions and which has a reliable latching mechanism associated therewith.
As discussed above, an improved electrical connector overcoming the shortages of existing technology is needed.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide an electrical connector assembly with high-density configuration and high data transmitting rate, and easily mating to and discrete from a complementary connector.
In order to achieve the above-mentioned objects, an electrical connector assembly, comprises: a housing having a receiving room therein communicated with an exterior along a longitudinal direction and defining a receiving cavity formed on a top surface thereof, a pair of supporting posts formed in the receiving cavity; two paralleled printed circuit boards received into the receiving room and positioned in the housing; a latching member located in the receiving cavity and engaged with the housing; and a pulling member supported by the top surface of the housing and having a front portion extending into the receiving cavity and interconnected with the latching member, the pulling member defining a curving portion supported by the pair of supporting posts.

Two screws 9 are passed through the two through holes 8151 and received into the receiving holes 53 to interlock the metallic holder 8 and the strain relief 5. As the strain relief 5 is disposed in the housing 1, so the metallic holder 8 is indirectly positioned with the housing 1 through the screws 9.
Referring to FIGS. 1 to 11, the assembling process of the electrical connector assembly 100 made in according to the present invention starts from soldering the conductors 41 of each cable 4 to the terminating section 22 of the printed circuit board 2. Thus, two combinations of the cable 4 and the printed circuit board 2 are accomplished.
Then, turning over the first shield part 15 to make the opening 152 facing upward and assembling a combination of the cable 4 and the printed circuit board 2 into the first shield part 15 through the opening 152. The printed circuit board 2 is supported by the first positioning posts 153 along a vertical direction. The printed circuit board 2 is positioned with the first shield part 15 along a front-to-rear direction due to two 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 a rear end of the shield part 15.
Then, assembling the strain relief 5 to a rear end of the first shield part 15. And, the ring 42 of the cable has a half portion received into a corresponding structure of the first shield part 15. The ring 42 has another half portion received into a recess 51 of the strain relief 5.
Then, assembling the spacer 3 into the first shield part 15. The spacer 3 is positioned with the first shield part 15 and located on the first PCB 21. The pair of second positioning posts 154 of the first shield part 15 pass through the corresponding two grooves 32 of the spacer 3 along an up-to-down direction to limit a movement of the spacer 3 along a front to rear direction.
Then, assembling another combination of the printed circuit board 2 and the cable 4 together into 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 two slots 231 of the printed circuit board 2 cooperated with the pair of second positioning posts 154 of the first 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 another recess 51 of the strain relief 5.
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 are received into the receiving room 11 of the housing 1 and positioned in the housing 1.
Then, assembling the latching member 6 to the pulling member 7 together through following steps. Firstly, the latching member 6 is disposed in front of pulling member 7 and arranged perpendicular to the pulling member 7. Secondly, the actuating section 73 of the pulling member 7 is passed through the rectangular hole 621 of the latching member 6 and located below the latching member 6. Thirdly, the latching member 6 is rotated 90 degree to make the latching member 6 and the pulling member 7 arranged in line. Thus, the latching member 6 is interconnected with the pulling member 7. And, the latching 6 is not easily discrete from the pulling member 7 due to the width of the actuating section 73 is wider than the rectangular hole 621.
Then, assembling the latching member 6 and the pulling member 7 together to an exterior surface of housing 1. The connecting section 72 of the pulling member 7 is located on the first surface 121 of the body portion 12 of the housing 1. The curving section 722 of the pulling member 7 is supported by the pair of supporting posts 143 located in the receiving cavity 14. Thus, the pair of supporting posts 143 are attached to a bottom surface of the curving section 722 of the pulling member 7. The operating section 71 of the pulling member 7 extends rearwardly and is beyond the rear surface of the housing 1. In addition, the latching member 6 is received into the receiving cavity 14. Thus, the actuating section 73 of the pulling member 7 is disposed between the latching member 6 and the third surface 141 of the receiving cavity 14. The retaining portion 61 of the latching member 6 is engaged with the housing 1. The connecting portion 62 of the latching member 6 is located above the third surface 141. 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. 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.
Finally, assembling a metallic holder 8 to the housing 1. The main portion 81 of the metallic holder 8 binds the first part 15, the second shield part 16 and a portion of the pulling member 7 together. 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. The strain relief 5 is also limited in the housing 1 by the metallic holder 8 through the pair of screws 9. The rear end of the latching member 6 and the front end of the pulling member 7 is shielded by the shielding portion 82 of the metallic holder 8.
After the above assembling steps, the entire process of assembling of the electrical connector assembly 100 is finished. The electrical connector assembly 1 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.
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.
