Abstract: An in-tank type fuel pump prevents electrical connection from terminals corroding by discharging foreign substances such as water, degraded fuel and the like entering its electrical connector unit. A terminal protrudes outwardly from a pump case inside a cylindrical terminal housing formed integrally with a pump cover of the fuel pump. A hole which is different from a terminal inserting hole is formed at a bottom portion of the terminal housing to permit fluid to flow therethrough and to connect the pump housing with the terminal housing. Therefore, since liquid having a large specific gravity such as water, degraded fuel and the like in the electrical connector unit is discharged to the outside of the electric connecter by the fluid injected to an internal portion of the terminal housing, the terminal of the electric connecter unit can be prevented effectively from corroding.

Abstract: An electrical connector assembly for a wiring harness and connectable to a control module includes a vent tube for venting the interior of the control module.

Abstract: Apparatus and methods for reducing the risk of flashover during loadbreak operations of insulated separable connectors. In one aspect, the flashover distance for an electrical connector assembly is increased by supplementing exposed conductive portions of the male connector with insulated portions such that energized points on the energized connector are placed a greater distance away from the nearest ground plane on the complimentary connector. The additional insulation compensates for reductions in dielectric strength of the air occurring during separation of the male connector from the female connector. Also, the semi-conductive ground shield of the bushing is supplemented by an insulating sleeve. The insulative sleeve effectively removes a common ground plane to which an arc might tend during a flashover. In another aspect, a substantial airtight seal is prevented between elastomeric seals of the female connector and the probe of the male connector.

The connection is between a first electrical conductor extending from a non-hazardous area and a second electrical conductor extending through the wellhead barrier. The second conductor includes a conductive portion circumscribed by insulation. The first and second conductors are electrically and mechanically coupled to form a connection. A breather boot protects the connection from moisture, the breather boot including an inner cavity for containing the coupling. A first opening receives the first electrical conductor and a second opening receives the second electrical conductor within which the insulation is terminated.

Abstract: Disclosed is a corrosion-free connector-structure of a fuel pump used in a vehicle fuel supply system. An electrical connector portion of a fuel pump is shaped into a square tube and its tubular wall is formed with a lock window for engagement with an engagement nail of a female connector and a fluid discharge port at an upper and lower portion thereof, respectively. As gasoline fuel level in the fuel tank lowers, the connector portion is exposed to air in the fuel tank and gasoline in the upper space within the connector portion or tubular wall pushes down and discharges water and degraded gasoline remaining in the lower space within the connector portion through the discharge port. Since water and degraded gasoline will not remain within the connector portion, electrical connector members or electrodes may be prevented from corrosion.

Abstract: Devices for use with high voltage system components for the safe expulsion of conductive moisture within such components include elbow and T-shaped connector bodies composed of insulating elastomeric bodies covered with conductive elastomer layers. The horizontal legs include all components normally found in such components. The bore of the vertical leg provides a circuitous passage from the horizontal leg to a container or the soil for the collection of such moisture. The circuitous path prevents the moisture from leaving as a stream and the grounded metal cap at the vertical leg extremity discharges any charge carried by the moisture. The circuitous path can be provided by modules each having a curved, linear or combined path such that the total path is longer than the length of the vertical leg. A vacuum access port can provide a means to draw out the moisture if gravity is insufficient to withdraw the moisture from the high voltage system components.

Abstract: Electrical connectors are provided with an electrically insulating base member having a connector mounting portion from which at least one pair of mounting lugs extend from an interior surface thereof. A pair of spaced-apart clamp-type connectors, each of which includes a clamp member having a generally U-shaped portion, are provided so as to resiliently engage (and thus mount) an electrical component (e.g., a cylindrical type lamp). The connectors define mounting holes for receiving a respective one of the mounting lugs, whereby the connectors are mounted to said insulating base member. A pair of ribs is provided on the connectors (preferably adjacent the mounting holes) so as to establish a vent space between said connectors and the interior surface of the base member's connector mounting portion. The established vent space allows heat generated during use of the electrical component to dissipate.
