The present disclosure is directed to high density coupling panels and, more specifically, to high density panels incorporating couplers that electrically couple pairs of connectors; each connector coupled to a singled twisted pair of conductors.
A single twisted pair of conductors can be used to transmit data and/or power over a communications network that includes, for example, computers, servers, cameras, televisions, and other electronic devices including those on the internet of things (IoT), etc. In the past, this has been performed through use of Ethernet cables and connectors that typically include four pairs of conductors that are used to transmit four differential signals. Differential signaling techniques, where each signal is transmitted over a balanced pair of conductors, are used because differential signals may be affected less by external noise sources and internal noises sources such as crosstalk as compared to signals that are transmitted over unbalanced conductors.
In Ethernet cables, the insulated conductors of each differential pair are tightly twisted about each other to form four twisted pairs of conductors, and these four twisted pairs may be further twisted about each other in a so-called “core twist.” A separator may be provided that is used to separate (and hence reduce coupling between) at least one of the twisted pairs from at least one other of the twisted pairs. The four twisted pairs and any separator may be enclosed in a protective jacket. Ethernet cables are connectorized with Ethernet connectors; a single Ethernet connector is configured to accommodate all four twisted pairs of conductors. However, it is possible that data and/or power transfer can be effectively supported through a singled twisted pair of conductors with its own more compact connector and cable. Couplers that can enable electrical coupling of connectors, with each connector coupled to a single pair of electrical conductors, are an important element in broadening the use of data and/or power transfer over a single pair of electrical conductors. A further element in broadening the use of data and/or power transfer over a single pair of electrical conductors is a high density coupling panel.
A high density coupling panel of the present disclosure presents a compact grouping of coupler wherein each of the couplers couples a first free connector with a second free connector wherein each of the free connectors is coupled to exactly two electrical conductors. The high density coupling panel can be manufactured in a shielded (e.g., metal) or non-shielded (e.g. non-metal) form as appropriate to a specific application. In the shielded configuration, a bonding strip is used to connect all metal components (e.g., shielded free connectors, shielded couplers, and metal panel of the high density coupling panel) to ground via a shielding tab.
In certain aspects, the present disclosure is directed to a high density coupling panel that includes a panel module, a coupler, a metal panel and a bonding strip. The panel module includes a plurality of channels. A shielded coupler is inserted within each of the plurality of channels and each coupler includes exactly one pair of electrical and data coupling contacts. The metal panel receives the panel module and a bonding strip electrically couples the metal panel and shield couplers to a shielding tab that is coupled to ground.
Another aspect of the present disclosure is directed to a method of assembling a high density coupling panel, including inserting a panel module, that includes a plurality of channels, into a panel until the panel module is releasably secured therein and inserting into each of the plurality of channels a coupler, which includes exactly two electrical and data coupling contacts, until the coupler is releasably secured therein.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
The present disclosure is directed to a high density coupling panel. The high density coupling panel generally comprises a metal panel, a plurality of panel modules and a metal bonding strip. Each of the plurality of panel modules includes a plurality of channels into which are inserted shielded couplers. The couplers are configured to couple shielded first and second free connectors, each of which is coupled to exactly two metal conductors that both conduct electricity and transmit data. The panel modules are inserted into the panel, the couplers are inserted into the channels of the panel modules, and a bonding strip operates to electrically couple the couplers (and free connectors coupled thereby) and the panel to a shielding tab to provide a grounded configuration.

The forward connector body 202 includes an elongate forward portion 210 and a rear receiving portion 212 that is separated by a shoulder 211.
The elongate forward portion 210 of the forward connector body 202 includes a forward face 223 having a pair of offset openings 224a, 224b corresponding to contact receiving channels 226a, 226b; the openings 224a, 224b receive pin contacts that electrically interface with the tuning fork contacts 206a, 206b. In certain embodiments, a recess 228 is provided on each side face of the elongate forward portion 210 to interface with and retain the metal frame 204. Each recess 228 includes a recessed notch 229 to receive an interfacing tab 244 of the metal frame 204 to further ensure that the metal frame 204 remains secured to the forward connector body 202. The forward connector body 202 also includes a cantilevered latch 230.
The rear receiving portion 212 of the forward connector body 202 is unitary (e.g. molded as a single unit) with the elongate forward portion 210 of the forward connector body 202. The rear receiving portion 212 defines a central cavity 232 that provides rear access to the contact receiving channels 226a, 226b of the elongate forward portion 210. Each side face 231, 233 of the rear receiving portion 212 includes a slot 235 to interface with the rear connector body 208 and an outward extending tab 237 to interface with the metal frame 204.
The metal frame 204 of the free connector 200 comprises a metal shell body 240 having a central cavity 234 that is slidable over the rear receiving portion 212 of the forward connector body 202. The metal frame 204 is held in place about the rear receiving portion 212 through use of a pair of flex tabs 242 that interface with corresponding recesses 228 of the forward connector body 202. Each of the flex tabs 242 includes in inward facing tab 244 to interface with recessed notch 229 of the forward connector body 202. Each side face 246, 248 of the metal frame 204 includes an opening 250 to interface with outward extending tab 237 of the forward connector body 202. Each point of interface between the metal frame 204 and the forward connector body 202 assists in securing the metal frame 204 to the forward connector body 202. Each side face 246, 248 of the metal frame 204 is additionally equipped with an inward directed beam 252 (e.g. shield beam) to establish an electrical interface with a cable shield (foil or drain wire) of the cable carrying the single pair of conductors (e.g., see
Electrical contacts 206a, 206b each include a forward portion having a tuning fork receptacle contact 254a, 254b while a rear portion of each of the electrical contacts 206a, 206b includes an insulation displacement contact (IDC) 255a, 255b. Each tuning fork receptacle contact 254a, 254b includes a pair of opposing spring arms 60a, 60b presenting an angled opening to receive a pin contact. Each of the electrical contacts 206a, 206b includes a shoulder 256a, 256b that interfaces with a stop 258 (see
The rear connector body 208 of the free connector 200 includes a rear body portion 260 that defines a central cavity 272 into which is inserted a pair of conductors (e.g., conductors 12, 14). Each side face is provided with an elongate opening 274 into which the inward directed beams 252 of the metal frame 204 extend wherein an electrical interface with the foil (or drain wire) of a conductor within the cavity 272 is established. A latch (now shown) on a lower face of the rear body portion 260 interfaces with a cut-out (not shown) of the metal frame 204 to secure the rear connector body 208 to the metal frame 204. A lip edge 277 of the rear body portion 260 seats against a rear face 257 of the metal frame 204.
The rear connector body 208 of the free connector 200 includes a contact receiving portion 280 that extends forward from the rear body portion 260. The contact receiving portion 280 is essentially divided into a first half 282a to accommodate the upper positioned electrical contact 206a and a second half 282b to accommodate the lower positioned electrical contact 206b. The first half 282a of the contact receiving portion 280 includes an upward channel that is contoured to direct the end of a conductor upward (e.g., a 90 deg. bend) to extend through a contact receiving slot. The second half 282b of the contact receiving portion 280 includes a downward channel that is contoured to direct the end of a conductor downward (e.g., a 90 deg. bend) to extend through a contact receiving slot.
The IDC contacts 255a, 255a of the electrical contact 206a, 206b are inserted into their respective contact receiving slots to establish an electrical interface with the conductor extending there through. The IDC contacts 255a, 255b applies a normal force to the respective conductor and cuts through both the insulation of the conductor and a portion of the conductor itself to create the electrical interface. Note that the electrical interface is established without requiring crimping of the conductor to the electrical contact, i.e. the electrical interface is crimp-less. The upward channel is, in part, defined by an upper outward extending arm 294 while the downward channel is, in part, defined by a lower outward extending arm 296. Each of upper outward extending arm 294 and lower outward extending arm 296 interface with respective corresponding slots 235 of the forward connector body 202 when the free connector 200 is assembled to assist in aligning and stabilizing the rear connector body 208 relative to the forward connector body 202.
