Embodiments of a securing system for plug connectors may have an adapter and a pair of housing parts, each with at least one plug place with a plug place interface for receiving the adapter whose exterior may have an adapter interface for positioning in the plug space. The adapter may have an interior geometry for receiving a plug connector. The exterior of the adapter and the plug place may form a primary securing means for securing the adapter in the respective plug place when the adapter is inserted into a defined plug position to secure the adapter in the plug place. Embodiments may include a secondary securing means, which can be plugged into the housing part up to a defined end position at which the secondary securing device to secure the plug connector in the adapter.

A multi-line electrical assembly that includes a multi-line cable (14), including a multiplicity of insulated conductive wires (59); and a multi-line electrical plug (16), physically connected to the cable. The plug has a housing (56) and a plurality of spaced-apart printed circuit hoards (PCBs, 48), housed in the housing and having a first end (47) that is connected to the cable and having a second end (46), separated from the first end. Further, the PCBs bear a plurality of conductive traces (50), at least some of the traces being electrically connected to the wires proximal to the first end. The traces terminate proximal to the second end.

A convertible force latching system includes two complementary connector bodies. Each connector body has a first mating face under which two series of magnets oriented alternating directions. A moving portion of the latching system allows the connector bodies and the magnets within to alter their alignment by the interaction of a user along a predetermined motion path. In a first arrangement, the series of magnets are aligned with such that the magnets of one connector body are attracted to the magnets of the other connector body. When the user actuation shifts the moving portion, the second arrangement positions the series of magnets such that they are aligned such that the magnets of one connector body are repelled to the magnets of the other connector body.

A multi-core connector used for 5G communication repeater, in which as a 5-core connector, with respect to prior art, an overall diameter is reduced from 32-35 mm to about 24.10 mm; the maximum external diameter is reduced from about 39.73 mm to about 27.70 mm, increasing an adaptive frequency from DC-20 GHz to DC-40 GHz to meet a demand of mmWave; an outer conductor of a female connector and that of a male connector abut against each other, so a gap possibly existed in the prior art is cancelled in a contacting interface, so as to enhance a shielding effect; in order to improve a push-on accuracy and avoid a traditional blind mate, right orientation indicating marks are set on a cylindrical surface of the male connector and that of the female connector, respectively; at least two bayonets are arranged circumferentially on an outer insert guiding surface of a male connector shell, and grooves matched with the bayonets are arranged circumferentially on an inner receptacle guiding surface of a female connector shell; a cylinder surface of a coupling nut is provided with spiral grooves, thus after the bayonets enter the spiral grooves, once the coupling nut is rotated up to an angle, the plug and socket can be clicked.

An electrical connector for a compressor of an HVAC system includes electrical leads and a plug communicatively coupled to the electrical leads. The plug includes a plug body and first connectors configured to electrically couple the electrical leads to second connectors of the compressor via engagement of the first connectors with the second connectors. The first connectors are symmetrically distributed on the plug body such that the first connectors can align with the second connectors in a plurality of alignment orientations of the first connectors and the second connectors. The plug also includes at least one interference projection radially extending from a periphery of the plug body. The at least one interference projection is configured to physically interfere with a positioning guide of the compressor and block engagement between the first connectors and the second connectors in all except for one alignment orientation of the plurality of alignment orientations.

An electrical connector system for use with independently heated hoses includes a first electrical connector, a second electrical connector, a third electrical connector, and a fourth electrical connector. The first electrical connector includes a first key that mates with a second key of the second electrical connector. The third electrical connector includes a third key that mates with a fourth key of the fourth electrical connector. The first and second keys differ from the third and fourth keys, ensuring the electrical connectors are correctly connected.

An electrical plug connector, in particular an electrical pin connector socket for the power electronics in the automotive sector, comprising a plug connector body for receiving a contact device and comprising a shield. The plug connector body is designed for introducing into an opening of a housing part of a housing of an electronics unit. The plug connector body is designed in multiple parts and has at least one inner plug connector body and an outer plug connector body, which are positioned on opposite sides of the housing part. The inner plug connector part can be fixed in the housing of the electronics unit independently of the housing part. Securing means connect the plug connector bodies to one another so that the housing part is fixed between the plug connector bodies.
