An apparatus configured to couple to an electrical penetration assembly is disclosed in which the apparatus comprises a connector comprising an inorganic seal to seal an inorganic flange and/or housing to an electrical penetration assembly.

A cooling device for cooling at least one electric line which is connected to a plug connector part includes: a cooling module disposable on the at least one electric line and having a cooling channel for flowing coolant therethrough, the cooling module having two housing assemblies, each of which has a respective connection section and a flow opening molded onto the connection section, the two housing assemblies being separate in a preassembly state and being connectable together to be placed on the at least one electric line such that the at least one electric line is received between the housing assemblies. The flow openings of the connection sections of the two housing assemblies are fluidically connected together to form the cooling channel.

The invention relates to a plug connector plug for a plug connector having an increased vibratory strength, comprising a plug connector plug housing with at least one contact element which is introduced into a receiving chamber of the plug connector plug housing, the contact element being elastically mounted and/or positioned with an elastomer element in the receiving chamber of the plug connector plug housing. The invention further relates to a plug connector comprising such a plug connector plug.

An electrical connector which is designed to be connected and coupled in a direction of introduction to a corresponding electrical connector, the electrical connector having a coupling element extending in the direction of introduction. The coupling element has a first protuberance extending in a first direction perpendicular to the direction of introduction and at least one second protuberance extending in a second direction which is perpendicular to the first direction and to the direction of introduction.

A connector device according to one or more embodiments includes a male connector including multiple male contact pieces, and a male contact piece retention portion, and a female connector including multiple female contact pieces, and a female contact piece retention portion. The male contact piece retention portion has multiple concentrically formed convex portions. The multiple male contact pieces are mounted on an outer circumferential wall of the convex portions, and arranged concentrically, with a tip end thereof being inclined toward the center of the convex portions. The female contact piece retention portion has concentrically formed multiple concave portions. The multiple female contact pieces are mounted on an inner circumferential wall of the concave portions, and arranged concentrically, with a base end thereof being inclined toward the center of the concave portions. The convex portion and the concave portion are brought into contact and tightly fitted with one another.

Disclosed is a connector capable of improving heat dissipating performance while suppressing an increase in size. This connector 10 is provided with a housing 26 made of a synthetic resin and having a facing surface 28 facing a mounting target, a connection terminal 34 accommodated within the housing 26, an electric power conductor 32 connected to an end of a power line 30 and accommodated within the housing 26, and a shield shell 36 made of metal and covering the housing 26, wherein the shield shell 36 has an extending part 87 covering the facing surface 28 of the housing 26, the housing 26 has a first accommodating recess 52 accommodating a first fastening member 50 made of metal and fastening the connection terminal 34 and the electric power conductor 32, and a second accommodating recess 68 accommodating a second fastening member 66 made of metal and fastening the housing 26 and the extending part 87 of the shield shell 36, the first accommodating recess 52 and the second accommodating recess 68 being adjacent to each other with a shared resin wall 70 interposed therebetween.

An electrical feedback barrier is configured to safely interconnect an intrinsically safe power supply to a non-intrinsically safe electrical load device in a hazardous environment. Electrical feedback from the non-intrinsically electrical load device is blocked by the electrical feedback barrier to protect the intrinsically safe power supply from adverse operating conditions. The electrical feedback barrier and the electrical load device are enclosed in an explosion-proof or flameproof enclosure for compliance with electrical equipment safety standards in the hazardous environment.
