A terminal connection unit has a novel structure that enables advantageously absorbing tolerance between positions of a terminal fitting and a connection portion while also ensuring a good state of connection between the terminal fitting and the connection portion. A terminal connection unit includes: a current-carrying member that has a connection portion for connection to a terminal fitting provided at the terminal end of an electric wire; and a support portion that fixedly supports the current-carrying member. The current-carrying member includes a fixing portion that is fixed to the support portion, and an extendable portion that couples the connection portion and the fixing portion to each other and can extend and contract in the first direction. The support portion includes an attachment portion that is attached to the connection portion and is displaceable in a first direction.

A connector includes a terminal fitting, a housing that houses the terminal fitting at a housing complete position, and a terminal retaining member that, at an assembling complete position to the housing, retains the terminal fitting remaining at the housing complete position. The terminal fitting includes a penetration hole. The terminal retaining member includes a retaining protrusion that is, at the assembling complete position, inserted into the penetration hole at the housing complete position, and retains the terminal fitting while the terminal fitting remains at that position. The penetration hole is formed to have a left-right asymmetric shape including a first hole part on the left side and a second hole part having a shape different from a shape of the first hole part and arranged on the right side of the first hole part.

The housing includes a protecting portion for protecting the terminal. The protecting portion projects in the first direction from the facing surface. A projection amount of the protecting portion is larger than that of the terminal. The protecting member includes a first through hole for insertion of the terminal and a second through hole for insertion of the protecting portion. The protecting member is displaced between a first position between a tip of the protecting portion and a tip of the terminal in the first direction and a second position between the tip of the terminal and the facing surface in the first direction.

Provided are embodiments for an electrical connector system. Embodiments include an electrical connector and a support ring where the support ring includes a baseplate having a first side and a second side, a recessed portion on a first side of a baseplate for a primary O-ring, and a sidewall extending from the second base plate. Embodiments also include a housing coupled to the support ring, wherein the sidewall extends into the housing, wherein the support ring is coupled to the electrical connector on the first side, and the support ring is coupled to the housing on the second side. Also provided are embodiments for the support ring and assembling the electrical connector system.

An electrical feed-through includes: a feed-through component having an opening; at least one conductor sealed into the opening of the feed-through component in a glass material or a glass ceramic material; and at least one guide component connected to the feed-through component, the at least one guide component including a material that is a plastic.

A mounting assembly for an electrical fixture has an upper unit and a lower unit. The upper unit includes a first portion of a detent mechanism and an upper contact for connection to a power source. The lower unit is configured for connection to an electrical fixture and includes a second portion of a detent mechanism and a lower contact for connection to the electrical fixture. When the lower unit engages the upper unit, the first portion and the second portion of the detent mechanism cooperate to releasably retain the upper unit and lower unit together and the upper contact and lower contact touch to create an electric pathway between the power source and the electrical fixture.

A device connector is provided with a terminal block including a resin housing having a tubular portion and three or more terminals, and a connector cover for covering one end side opening of the tubular portion. Connecting portions of the three or more terminals project from a first partial inner peripheral surface toward a second partial inner peripheral surface of the tubular portion. The connector cover includes an inserting portion to be inserted into the tubular portion, a resin cover portion having separation walls and a sealing ring. The plurality of separation walls respectively partition the three or more connecting portions. First ribs project along the first partial inner peripheral surface from each of the plurality of separation walls, and second ribs extend along the second partial inner peripheral surface from each of the plurality of separation walls.

A mounting plate for an electrical outlet includes a central region having a front surface, a rear surface, and an opening for accessing an outlet. A first mounting tab and a second mounting tab extend from the central region at an angle. The mounting plate may be used to attach an outlet to an outlet housing having a wiring compartment and a panel at least partially enclosing the wiring compartment. The panel has a front wall and an opening for receiving an outlet.

A connector that prevents damage to an electric circuit provided inside a connecting object is provided. Two shield cables constituting a wire harness, a cable-side connector accommodating a distal end of the shield cable, and a device-side connector secured to a unit case are included. The cable-side connector includes a conductive shield shell including a shell body and a shell cap member, and a female housing that is made of an insulating resin and accommodated in the shield shell to allow the shield cable to be inserted therein. The shell securing portion for securing together the shell body and the shell cap member is provided in a position to oppose in the fastening direction of the bolt the device-side securing portion that secures the device-side connector to the unit case.

Provided is a wall bushing for establishing contact between a plug connector and a housing wall or the like. The wall bushing can be placed and fastened over an opening by three fastening bores. Advantageous arrangement of the three fastening bores ensures that the wall bushing is fitted on the housing in a particularly safe and stable manner. The special shaping of the wall bushing additionally allows a high mounting density of a large number of wall bushings in a small area.
