A connector device including: a plug which has a plug housing and at least one electrical plug contact that is held so as to be insulated in the plug housing; and a socket which has a socket housing and a socket contact. The socket housing has an electrically insulating plug channel for receiving the plug contact, in which plug channel the socket contact is located. A sleeve is rotatably arranged on the plug housing or the socket housing. A slotted guide arrangement is operatively disposed between the sleeve, the plug housing and the socket housing. A slotted guide of the slotted guide arrangement has a separating portion having a slope relative to a circumferential direction. After the separating portion in an opening direction, a delay portion is located, which has a smaller slope than the separating portion.

A connector 10 is provided with a connector housing 15 including a wire draw-out opening 20, a terminal 14 accommodated in the connector housing 15, a wire 12 connected to the terminal 14 and pulled out to outside of the connector housing 15 through the wire draw-out opening 20, and a bracket 22 made of metal for holding the wire 12 pulled out through the wire draw-out opening 20. The bracket 22 includes a first holding portion 24 and a second holding portion 26 to be fixed to each other while sandwiching and holding the wire 12 from both sides in a direction perpendicular to an axis of the wire 12, and a fixing portion 139 to the connector housing 15.

A connector includes a back housing, a front shell having a barrel portion and a grounding portion continuous with a rear portion of the barrel portion, and a cover shell. The cover shell has a contacting portion contacting a rear end upper portion of the front shell, a catching portion catching on the grounding portion, and a spring portion elastically deformed by catching of the catching portion. The elastic deformation of the spring portion causes the cover shell to contact the back housing while pressing the back housing frontward, and to contact the front shell while pressing the rear end upper portion of the front shell upward at the contacting portion.

A terminal block of a novel structure is disclosed which can improve the heat dissipation performance of a terminal while achieving a size reduction with a small number of components. The terminal block is provided with a terminal including a connecting portion to be connected to a mating terminal on a tip side and a fixing portion on a base end side, a shield shell made of metal and including a tubular receptacle for surrounding the connecting portion of the terminal, a holding tube portion for surrounding the fixing portion of the terminal and a contact portion to be held in thermal contact with an external heat dissipation target and a filling resin portion for integrally fixing the fixing portion of the terminal to the holding tube portion of the shield shell by filling up between facing surfaces of the fixing portion and the holding tube portion.

A wet connect, including a first component having a first signal conductor, a first connector operably connected to the first signal conductor, a second component having a second signal conductor, and a mating connector operably connected to the second signal conductor. A method for wet connecting components including running a second component into connection with a first component without orienting the second component to the first component. A wellbore system, including a borehole in a subsurface formation, a string in the borehole, a wet connect, disposed within or as a part of the string.

A quick-change structure for liquid-cooled charging gun, comprises a charging connector main assembly; one side of the charging connector main assembly is fixedly connected with a terminal fixing assembly, and a detachable quick-change terminal is arranged inside the terminal fixing assembly; the front side of the charging connector main assembly is provided with a detachable quick-change gun connector head assembly. The detachable structure realizes effective saving of excessive maintenance costs, labour-hours and material costs. Worn out terminals can be completely replaced within a few minutes after the power is confirmed cut off, and no other actions are required on the charging connector end or harness end. Merely using special tools to disassemble the terminal that needs to be replaced, reassembling and resetting, the quick replacement of wearing parts can be done. Maintenance costs and technical ability requirements for maintenance and replacement are lowered, and rapid replacement and maintenance is realized.
