The assemblies are insertable into the housing defining modular jacks in the outer housing.
Description




BACKGROUND OF THE INVENTION




The invention relates to a connection assembly providing multiple port connections.




Known connector assemblies exist having multiple receptacle connectors in a common housing, which provides a compact arrangement of such receptacle connectors. Such a connector assembly is useful to provide multiple connection ports. Accordingly, such a connector assembly is referred to as a multiple port connector assembly. In preferred arrays, the housing has jacks one above the other, forming a plurality of arrays in stacked arrangement, so-called stacked jack arrangements. The receptacle connectors, that is, modular jacks, each have electrical terminals arranged in a terminal array, and have plug receiving cavities. Specifically, the receptacle connectors are in the form of RJ-45 type modular jacks that establish mating connections with corresponding RJ-45 modular plugs.




For example, as disclosed in U.S. Pat. No. 5,531,612, a connector assembly has two rows of receptacle connectors, that is, modular jacks, arranged side-by-side in an upper row and side-by-side in a lower row in a common housing, which advantageously doubles the number of receptacle connectors without having to increase the length of the housing. The receptacle connectors have plug-receiving sections with plug receiving cavities that are profiled to surround modular plugs that are to be inserted in the cavities. The modular plugs have resilient latches, which engage with latching sections on the modular jacks. The latches are capable of being grasped by hand, and being resiliently bent inwardly toward the plugs to release them from engagement with the latching sections on the modular jacks.




One application for such connector assemblies is in the field of telephony wherein the modular jacks provide ports for connection with a telephone switching network of a telephone service provider, such as, a regional telephone company or national telephone company. The corresponding RJ-11 modular plugs terminate opposite ends of telephone cords leading to wall mounted telephone outlets inside a building. The telephone outlets connect to telephone lines outside of the building, which, in turn, connect to the telephone switching network of the telephone service provider.




Alternatively, such connection systems have found utility in office computer networks, where desktops are interconnected to office servers by way of sophisticated cabling. Such networks have a variety of data transmission medium including coaxial cable, fiber optic cable and telephone cable. One such network topography is known as the Ethernet network, which is subject to various electrical standards, such as IEEE 802.3 and others. Such networks have the requirement to provide a high number of distributed connections, yet optimally requires little space in which to accommodate the connections.




Furthermore, such networks now operate at speeds of 1 gigabit and higher which requires significant conditioning to the signals. For instance, it is common to require shielding for controlling electromagnetic radiation per FCC standards, while at the same time controlling electromagnetic interference (EMI) within the assembly, between adjacent connections. It is therefore also a requirement to provide such components within the assembly as magnetic coils, inductors, chip capacitors, and the like, to condition the signals. While the technology exists for conditioning the signals, no connection devices exist which are capable of handling such speeds, while at the same time package the signal conditioning components required to maintain these speeds.




Another design is shown in U.S. Pat. No. 6,227,911 to Boutros et al., which discloses a modular jack assembly having multiple ports for connection to multiple modular jacks. While this assembly further discloses having packaged magnetic assemblies, or other components, this design, as in other attempts to signal condition connection devices, simply adds the components to known connection devices. Therefore the volume within the assembly is inadequate to provide the proper signal conditioning devices for the high speeds now required.




The objects of the inventions are therefore to overcome the shortcomings of the prior art.




BRIEF SUMMARY OF THE INVENTION




The objects of the invention have been accomplished by providing an electrical connector assembly, which comprises a housing member having a front mating face having at least two openings therethrough, profiled to receive a plurality of electrical plugs, wherein the openings are positioned one above the other.
