Securing means connect the plug connector bodies to one another so that the housing part is fixed between the plug connector bodies.

Disclosed is a fast self-adaptive rotary plug-in underwater force-bearing connector, which comprises a plug part and a socket part, wherein the plug part comprises a plug housing, a pin arranged in the plug housing, and a push-pull sleeve, a rotary sleeve, a front retaining ring, a ratchet lock nut and a rear retaining ring arranged outside the plug housing; the socket part comprises a socket housing and a jack arranged in the socket housing; the pin and the jack cooperate to connect the plug part and the socket part. The fast self-adaptive rotary plug-in underwater force-bearing connector of the present application can work under the working condition of a large tensile force and has a high reliability.

A busbar assembly is disclosed herein. The assembly includes a ring body having a plurality of openings extending in an axial direction and configured to receive electrical wire connections, and a plurality of phase conductors. A high-voltage connection portion is also included in this same body. The high-voltage connection portion includes a plurality of high voltage conductors each configured to engage a respective one of the plurality of phase conductors. A plurality of connectors are each attached to a respective one of the plurality of high voltage conductors. A seal is arranged on a periphery of the high-voltage connection portion to incorporate the busbar into one combined simple design.

A connector includes a terminal, a housing, and a temperature sensor. The terminal includes a terminal connection portion that is electrically connected to a counterpart terminal, a wire connection portion that is electrically connected to a wire, and a tubular portion that is located between the terminal connection portion and the wire connection portion and is formed in a tubular shape having a space portion (accommodation space portion). The temperature sensor is disposed in the space portion of the terminal. The tubular portion is accommodated inside the housing in a state where the terminal is held by the housing.

A spring-loaded connector (2) includes a waterproof elastic member (50). The waterproof elastic member (50) includes cylindrical parts (51) corresponding to respective contact units (10). When the cylindrical part (51) is sandwiched between a first pin (11) and an intermediate member (13) of the corresponding contact unit (10), the waterproof elastic member (50) seals between the first pin (11) and the intermediate member (13) in a watertight manner while allowing the contact unit (10) to penetrate. The waterproof elastic member (50) includes, between the cylindrical parts (51) that are adjacent to each other, a water-shielding structure (52) for preventing the first pins (11) of the contact units (10) corresponding to the adjacent cylindrical parts from being electrically connected due to presence of water between the first pins (11).

A connector includes a connector housing and a shield shell. A terminal electrically connected to an end part of a wire is arranged inside the connector housing. The connector housing includes an inserting portion to be inserted into a mounting hole provided in a conductive case for accommodating an inverter and an outer arrangement portion integral with the inserting portion and to be arranged outside the case. The shield shell includes a tubular covering portion for covering an outer periphery of the outer arrangement portion and is electrically connected to the case. A shield-side sealing member seals between an outer-peripheral surface of the outer arrangement portion and an inner-peripheral surface of the covering portion. The outer-peripheral surface of the outer arrangement portion has a second intrusion suppressing groove provided over the entire outer periphery of the outer arrangement portion between the shield-side sealing member and the inserting portion.

An electrical connector assembly includes a connector housing and a busbar having a rectangular cross section defining two opposed major surfaces and two opposed minor surfaces disposed within the connector housing. A planar surface is defined by one of the two opposed major surfaces of the busbar. The electrical connector assembly further includes a cooling plate that is sized, shaped, and arranged to be in conductive thermal contact with the planar surface of the busbar. The cooling plate is configured to reduce a temperature of the busbar.

A terminal module (10) is provided with a terminal fitting (12) to be connected to an end part of a cable (11), a rubber plug (13) to be held in close contact with the outer periphery of the cable (11), a housing (14) for supporting the terminal fitting (12), and a cover (15) to be mounted on the housing (14) to cover the terminal fitting (12). The rubber plug (13) is sandwiched and held between the housing (14) and the cover (15).

An electronic device includes a housing including a side wall having a first opening and a second opening provided at one side of the first opening; a tray configured to be inserted into or extracted from the housing through the first opening; and a waterproof member provided in the second opening and configured to reciprocate linearly, wherein the waterproof member includes: a pin member configured to linearly reciprocate within the second opening; and at least one waterproof ring protruding from an outer peripheral surface of the pin member and sealing a space between the outer peripheral surface of the pin member and an inner wall of the second opening, and wherein the second opening extends at an incline with respect to a direction in which the tray is inserted or extracted.
