A pin assembly includes a plurality of pins and a plurality of seals. The plurality of seals are separate from one another and are each formed from an elastically deformable material. The seals are each disposed on one of the pins and are each retained on the one of the pins by interaction of the elastically deformable material with the one of the pins.

The invention relates to an electrical connector (2) including a connector body (20), which includes at least one accommodation (21), and at least two electrical connecting organs (22, 22′), which each include at least one internal section (220, 220′) extending inside said at least one accommodation (21). This electrical connector (2) is characterized in that it includes electrical insulating means (23), which have a tracking resistance index, CTI, higher than 600, which are located at least inside said at least one accommodation (21), which surround at least the internal section (220, 220′) of the at least two electrical connecting organs (22, 22′), and which extend at least over the internal section (220, 220′) of the at least two electrical connecting organs (22, 22′).

The purpose of the present invention is to provide a feature making it easy to accommodate a terminal-equipped wire in a connector housing. This connector-equipped wire is provided with: a terminal-equipped wire comprising a jacketed wire and a terminal component that is provided to an end part of the jacketed wire; and a connector housing comprising a body component where a cavity has been formed and a cover component mounted onto the body component. A distal end part of the terminal component is accommodated in the cavity. A rear end part of the terminal component protrudes out to outside the cavity, and is covered by the cover component or by the cover component and the body component. In the state where the rear end part of the terminal component protrudes out to outside the cavity, the cover component can be mounted onto the body component in accordance with a sliding movement in a direction intersecting the longitudinal direction of the cavity.

A vehicular electrical plug or connector is provided. In another aspect, an electrical connector includes a wire cable having a first end that is permanently connected to a wheeled recreational vehicle, a second end with an outlet-engageable plug thereon, and a switch allowing for a high potential or dielectric withstand test by the vehicle manufacturer in one switch condition, and then the switch allowing for normal use while detecting and/or alerting a user of an electrical ground and/or polarity problem in another switch condition. A further aspect of an electrical connector employs multiple lights on a plug, one of which alerts a user of an electrical ground and/or polarity problem, and another of which is illuminated when electricity is flowing through the plug. Another aspect of a vehicular electrical plug and method of manufacturing same, includes liquid polyurethane fed into a hole in a plug housing which then fills the otherwise open area therein to create a water-resistant seal for the plug.

The present invention provides a dummy plug that can be automatically corrected to a normal orientation, and a dummy plug structure. A dummy plug (10) is provided with a square fitting part (12) extending in the longitudinal direction. The square fitting part (12) has four corner sections (15) at diagonal positions about the axis in the longitudinal direction. Each of the four corner sections (15) has a chamfered section (17) outwardly expanding rearward and having a rearwardly tapering width dimension in the direction about the axis. Each chamfered section (17) has a ridgeline section (18) extending in the longitudinal direction and protruding outward. Each ridgeline section (18) is inclined so as to be offset further in one direction about the axis as the ridgeline section (18) extends rearward.

A bicycle equipment is provided, including an electric power supply unit electrically connected to a first electric connector; a first component; a second component with an electrically powered device and a second connector. A through hole is provided in the first or second component. An electric connector assembly includes a third connector matching the first connector and permanently connected to the first component at a seat for the electric power supply unit; a fourth connector matching the second connector; and an electric cable extending between the third connector and the fourth connector. The through hole, the third connector and the fourth connector are sized such that the fourth connector may pass, in at least one orientation thereof, in the through hole and the third connector may not pass in the through hole.

A connector includes a resin housing to be assembled to a wall portion of a box-shaped body, a bus bar held by the housing and having a fastened portion that is disposed inside the wall portion and is to be connected to a terminal fitting by fastening using a bolt, and a nut held by the housing with a gap between the nut and the fastened portion, the gap allowing insertion of the terminal fitting and engaged with the bolt to fasten the fastened portion and the terminal fitting inserted into the gap together. In the bus bar, a recessed portion recessed such that the bus bar is cut off is provided inside the wall portion. The recessed is exposed to an outside of the housing without being covered with a resin constituting the housing.

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.

Various techniques are provided for displacing air from partial discharge sensitive regions of a connector of a low partial discharge high voltage connector to other regions of the low partial discharge high voltage connector where electrical flux is reduced. A plug member is mated with a receptacle member to provide the connector, with a seal member disposed in a cavity provided by the plug member and/or the receptacle member. In response to the mating, the seal member is compressed at an initial contact region between an innermost layer and an outermost layer of the seal member. In response to the compressing, air is forced radially inward toward the innermost layer and radially outward toward the outermost layer away from the initial contact region to reduce partial discharge associated with the connector. Additional methods and systems are also provided.

An electro-mechanical connection apparatus. The apparatus includes a connection base configured to mechanically support an external device, and a first connection device operably connected to the connection base, wherein the first connection device is configured to operably connect with a second connection device associated with the external device. The first connection device includes a first electrical contact configured to establish an electrical connection with a second electrical contact of the external device, wherein the first electrical contact establishes the electrical connection with the second electrical contact while the connection base mechanically supports the external device.
