The application discloses a connector and a connector assembly. The connector has a housing and a terminal retaining portion. The housing is provided with a cavity; the terminal retaining portion is disposed in the cavity and configured for fixing connection terminals; the terminal retaining portion is provided with a plurality of first mounting holes configured for accommodating first connection terminals and a plurality of second mounting holes configured for accommodating second connection terminals; the first mounting hole has a cross sectional size larger than that of the second mounting hole; the plurality of first mounting holes are disposed around all of the second mounting holes. Compared with prior art, in the connector assembly provided by the application, first through-holes are arranged around second through-holes, so that the connection terminals having larger sizes for larger current therethrough can be disposed at the surrounding and be farther away from each other to help reduce the internal temperature rise of the connector thus to be safe and convenient for use.

A system is provided comprising of a first plug module and a second plug module, which can be plugged together, wherein the first plug module has a locking arrangement, whereby the plug modules can be reversely locked to each other. The system can be arranged within the housings of industrial plugs and is thus better protected from mechanical loads.

Connector assemblies including a first subassembly having a recessed portion and a pair of locator tracks and a second subassembly having a pair of locator projections, vacuum assemblies including these connector assemblies, and methods of using the same are provided herein.

A connector includes a housing and a terminal held by the housing and having a mounting part adapted to be mounted on a connecting member. The housing has a recess part in which a for-connection portion of the connecting member is housed and held and a protrusion protruding higher than the thickness of the for-connection portion and defining the recess part. The protrusion is located only at a peripheral edge portion of the housing.

An arc prevention system including a jack having a receptacle, a modular plug sized to be positioned in the receptacle of the jack, the modular connector including, a plurality of contacts, with at least two of the contacts creating an energized electrical path with an external power source in electrical communication with the external power source, a latch extending from a top surface of the modular plug, a switching unit positioned on the latch, a control circuit in electrical communication with the switch and the at least two energized contacts, where the electrical path between the control circuit and the switching unit is not energized, and the control circuit adjusts the energized electrical path to a predetermined electrical level.

The present invention is a connector for connecting an electrical cable having cladding to an aperture in an electrical panel. The assembled connector has a spring, a shell, and a insulator along a longitudinal axis. The spring has a base from which two insertion tabs extend coaxial with the axis and the shell has two side walls to prevent over-insertion of the cladding into the connector. The insertion tabs of the spring have hook latches extending past the insulator that lock the connector in the panel, and the insulator has pressure buttons for flexing the insertion tabs during insertion and removal of the connector to the electrical panel.

A framing assembly is disclosed including a first connector and a second connector. The first connector includes a body defining an edge portion. The second connector includes a base and a flange in communication with the base. To interconnect framing components of the framing assembly, the second connector is engaged with the first connector such that an engagement surface of the flange abuts the edge portion of the first connector restricting movement of the second connector relative to the first connector.

A modular I/O device includes a terminal base with a terminal block that includes a plurality of wiring connectors. An auxiliary wiring device includes a plurality of auxiliary wiring connectors and is selectively physically connectable to the terminal base in an operative position and selectively physically removable from the terminal base. The terminal block includes a receiver and the auxiliary wiring device includes a body including at least one mounting tab that projects outwardly from the body and that is located in the receiver. The receiver includes a projecting lip about which the auxiliary wiring device is pivotable relative to the receiver on a pivot axis. The terminal base includes at least one catch and the auxiliary wiring device further includes at least one latch arm that is adapted to engage the catch when the auxiliary wiring device is physically connected to said terminal base in its operative position.
