An electrical connector assembly (100), comprises: a housing (1) having an upper shield part and a lower shield part (16) assembled with each other, and the upper shield part having at least two shield covers (15) arranged side by side along a transversal direction; a plurality of retaining pieces (9) assembled to each of two adjacent shield covers and interconnecting with the two adjacent shield covers; a plurality of printed circuit boards (2) disposed in the housing; a latch mechanism assembled to an exterior surface of the housing; and a metallic holder (8) surrounding and engaged with the housing.
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.
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.
And, I/O connector will has a developing trend to form multi-ports on a front end thereof to meet more and more higher data transmitting rate requirements of the server. As a result, a width of the electrical connector becomes larger. Thus, a latch formed on the electrical connector will be difficult to operate to achieve an engagement and disengagement between the I/O connector and the complementary connector.
Accordingly, an object of the present invention is to provide an electrical connector assembly with a latch mechanism easily operated.
In order to achieve the above-mentioned objects, an electrical connector assembly, comprises: a housing having an upper shield part and a lower shield part assembled with each other, and the upper shield part having at least two shield covers arranged side by side along a transversal direction; a plurality of retaining pieces assembled to each of two adjacent shield covers and interlocking with the two adjacent shield covers; a plurality of printed circuit boards disposed in the housing; a latch mechanism assembled to an exterior surface of the housing; and a metallic holder surrounding and engaged with the housing.

Secondly, each of the actuating section 73 of the pulling member 7 is passed through the rectangular opening 622 of the latching member 6 and located below the latching member 6. Thirdly, each of the latching member 6 is rotated 90 degree to make the latching member 6 and the actuating section 73 of the pulling member 7 arranged in line. Thus, the pair of latching members 6 are interconnected with the pulling member 7. And, the pair of latching members 6 are not easily discrete from the pulling member 7 due to the width of the actuating section 73 is wider than a width of the rectangular opening 622.
Then, assembling the pair of latching members 6 and the pulling member 7 together to an exterior surface of housing 1. The two connecting sections 72 of the pulling member 7 are located on the first surface 121 of the body portion 12 of the housing 1.

The operating section 71 of the pulling member 7 extends rearwardly beyond the rear surface of the housing 1. In addition, each of the latching member 6 is received into the receiving cavity 14. Thus, the retaining portion 61 of the latching member 6 is respectively disposed in a rear end of the receiving cavity 14 to make the latching member 6 engaged with the housing 1. The connecting portion 62 of the latching member 6 is located 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. 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 a body portion 12 of the housing 1 to bind the upper shield part, three strain reliefs 5 and the lower shield part 16 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. A portion of the latch mechanism is shielded by the metallic holder 8. Two holes 821 of each side wall 82 of the metallic holder 8 are respectively cooperated with the two wedge-shaped projections 17, 51 of the body portion 12 and the strain relief 5. Two holes 831 of the bottom wall 83 are cooperated with the two wedge-shaped projections 18.
