A secure locking and unlocking system includes a plug body that is cylindrical in shape, a locking ring and a notched washer. One face of the notched washer is positioned on the locking surface of the locking ring. The system further includes a holding pin that locks the position of a locking element and an upper ring mounted on the locking ring. The locking ring includes a ramp-shaped groove with a linear part, a rising ramp and a descending ramp. A ramp spring is configured so that the locking or unlocking movement of the upper ring is mobile and the locking ring is fixed. The upper ring includes a hole in which a lug is placed. The end of the lug cooperates with the ramp-shaped groove of the locking ring that guides the upper ring in relation to the locking ring.

A connection arrangement is for an electrical connection from an interior room of a sealed housing to an outside of the sealed housing. The connection arrangement includes a first connection line, a second connection line, and an interconnecting element. The first connection line is adapted to be electrically coupled to an electric source arranged outside the housing. The second connection line is adapted to be electrically coupled to an electric element arranged in the interior room. The first connection line is configured for being guided through an opening in a wall of the housing into the interior room. An end section of the first connection line and an end section of the second connection line are both electrically and/or mechanically connected to the interconnecting element to establish an electrical connection from the interior room to the outside of the sealed housing. The end section of the first connection line and the interconnecting element are both sealed using a sealing material with respect to the opening in the wall such that the interior room of the housing is sealed with respect to the surroundings of the housing.

A reliable contact is produced in a simple and inexpensive manner for an internal electric device surrounded by a housing. An electric connection device for a housing element of the housing has at least one external electric connection element on the housing element for connecting a supply line of the internal electric device to an external electric device outside the housing. At least one line section, electrically connected to the external electric connection element on one side, and at least one terminal element, connected to the line section on the other side, connect to the supply line of the internal electric device. The external electric connection element, the at line section, and the terminal element are fixed on the housing element, and the terminal element is an inner face of the housing element and accessible from an outer face in a vicinity of an assembly opening in the housing element.

An electrical connector is provided and includes a housing and a contact. The housing includes a retention wall with a contact receiving passageway. The contact is secured in the contact receiving passageway and includes a front press fitting section and a rear press fitting section positioned rearward of the front press fitting section by a pitch.

Provided is an electronic control device that is easily assembled and with which it is possible to reduce the effects of vibration and external force applied from a connector. Electronic components are installed on a substrate. A base covers a surface of the substrate. A cover covers a surface of the substrate. A first connector, which is installed on the surface, connects to a connector fixed to an on-board transmission. A second connector, which is installed on the surface, connects to a connector of a harness. First vibration-suppressing parts, which are provided to the inside surface of the base facing the end surface of the first connector on the surface side, suppress the vibration of the first connector.

A connector assembly for insertion into a hollow portion of a tool, fixture, or housing. The connector assembly may have a connector having two terminated end portions for reducing assembly time and cost with on-site termination. The connector assembly may include a first outer body having a hollow portion for insertion of at least a portion of a first insert-assembly sleeve portion. The connector assembly may have at least one retaining portion extruding radially inward and configured to be positioned into at least one radially inward groove of the first insert-assembly sleeve portion for securing at least a portion of the first terminated end portion in the first outer body. With this assembly, one of the terminated end portions without an outer body may be passed through the hollow portion and then assembled to the corresponding outer body and reinserted into an end of the hollow portion.
