Add-on housing for a plug-in connection, which add-on housing has a housing side with at least one first fastening form and a plug-in side with at least one holding form, wherein a flange is arranged between the housing side and the plug-in side, which flange is provided for attaching the add-on housing to an appliance housing, wherein the plug-in side has at least two holding forms, at least one first holding form and at least one second holding form.

A terminal module includes a circuit board having: an upper layer having a row of upper conductive pads; a lower layer having a row of lower conductive pads; a first upper signal layer having upper conductive vias and a first upper inner conductive trace connecting with corresponding upper conductive pads through the upper conductive vias; a first lower signal layer having lower conductive vias and a first lower inner conductive trace connecting with corresponding lower conductive pads through the lower conductive vias; and a ground isolation layer; and a row of upper mating terminals connected to the upper conductive pad, and a row of lower mating terminals connected to the lower conductive pad; wherein neither the upper conductive via nor the lower conductive via passes through the ground isolation layer, and the ground isolation layer shields electromagnetic interference between the upper mating terminals and the lower mating terminals.

The present invention provides a system comprising PoE apparatus including midspans, switches and routers that can provide high powered PoE connections that enable the recovery of DC power in sufficient quantities that allow it to be converted to AC power by way of an inverter. The invention also provides a method for providing AC power, data and light to office workstations using a single PoE connection. The invention further comprises a common mode signaling system that operates independently of any TCP/IP signal transmitted through an Ethernet connection wherein said signaling system is adapted to communicate with and control PoE powered devices.

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.

A receptacle connector with a cable-clamped structure of the invention includes a housing, an electrical module and a cable clamping module. The electrical module is disposed in the housing and includes a circuit board, a plurality of contacting terminals and a plurality of prick type terminals. The circuit board is disposed in the housing. The contacting terminals and the prick type terminals are disposed on the printed circuit board. The cable clamping module includes a first clamping member, a second clamping member and a cable clamper, wherein the first clamping member engages the second clamping member, and the cable clamper is pivoted to the first clamping member. A cable extends through the first clamping member and the second clamping member engaging the first clamping member, the cable clamper presses the cable with the first positioning portion positioned in the second positioning portion of the first clamping portion.

A plug arrangement for use with cables (K) having cable plugs (S) comprises a housing (1) for receiving the cable plug (S), a clamping element (5) encompassing the cable (K) and accommodated in the housing (1), which clamping element (5) clamps, in a compressed state, the cable (K), and a clamping sleeve (3) for establishing a threaded connection with the housing (1). When the threaded connection is tightened, the clamping element (5) is braced in the housing (1) and the cable (K) is clamped in the clamping element (5). The front end of the clamping element (5) facing the cable plug (S) is configured for receiving and positioning the cable plug (S) in a predetermined position at the front end of the clamping element (5) or is provided with at least one stop for the cable plug (S). Thus, when the threaded connection is tightened, the cable plug (S) is also positioned with respect to the housing (1) and the clamping element (5) so as not to rotate and fixed.

Provided is a secure quick communication system disconnect switch box that enables remote verification of communication path connection or disconnection status. The box utilizes a lid having an affixed jumper circuit/assembly bridging or coupling at least two network connections. When the lid to the switch box is attached, the at least two computers/networks are connected via the jumper circuit/assembly. When the lid is removed from the switch box, the jumper circuit/assembly is disconnected from the at least two computer/networks, thereby disconnecting and isolating the otherwise coupled computers/networks. Removal of the lid additionally exposes network maintenance/access ports to provide access to one or more of the computers/network. When the lid is closed, the network maintenance/access ports are inaccessible to the user.
