A connector includes: a terminal metal fitting that is connected to an electric wire and is configured to be inserted into a connector insertion hole of a metal case of a counterpart device from an opening; a housing includes a connector insertion part configured to be inserted into the connector insertion hole from the opening together with the terminal metal fitting; a liquid seal member that is configured to seal a gap between the housing and a rim of the opening in the case; a shield shell that includes a cylindrical accommodation body accommodating the housing therein, an annular flange configured to be opposed to an annular surface around the rim of the opening in the case, and a fixed part configured to be fixed to the case; and an annular interposed member that is configured to be interposed between the flange and the annular surface to be sandwiched therebetween.

An electrical connector assembly includes a connector housing defining a cylindrical terminal cavity, an electrical terminal having a cylindrical portion, and an electrical terminal seal. The electrical terminal seal includes a base formed of a compliant material and a cylindrical protrusion integrally formed with the base and extending from a major surface of the base. The electrical terminal seal defines a cylindrical aperture extending through the protrusion. The protrusion includes a first circumferential rib that is integrally formed with the protrusion. The first circumferential rib extends into the aperture from an inner surface of the protrusion.

A connector comprising a contact, a plunger, and a spring activated seal is provided. The contact is positioned within the housing and configured to transmit at least one of an electrical signal and an optical signal between the connector and a secondary device. The plunger is positioned within the housing and in communication with the contact. The spring activated seal comprises a flexible portion and a spring configured to urge the flexible portion to contact the housing and at least one of the plunger and a contact of the secondary device to form a fluid tight seal therebetween.

A connector (10) includes busbars (40A, 40B) including connecting portions (43) to be connected to terminals (101) of wires (100A, 100B) routed inside a case. Further, the connector (10) includes a housing (80) made of resin and including a separation wall (81) separating the inside and outside of the case. Further, the connector (10) includes a cover (90) made of resin and to be mounted on the housing (80) to cover the connecting portions (43). The busbar (40A, 40B) includes one end part provided with the connecting portion (43) and another end part on a side opposite to the one end part. The busbar (40A, 40B) is embedded in the separation wall (81) of the housing (80) and the one and the other end parts are exposed from the separation wall (81).

Systems and methods for sealing a pothead connection to prevent external fluids from leaking into an ESP motor. In one embodiment, a pothead housing has a set of sealing assemblies, where each of the sealing assemblies has a sealing body that is positioned in a port of the motor's housing to form a direct seal against both a corresponding motor lead extension cable and the motor housing. The sealing assembly has a pothead terminal that is electrically connected to the conductor of the corresponding cable. When the pothead is secured to the motor housing, the pothead terminal engages a corresponding motor housing terminal positioned in the port. The motor housing terminal is connected to the motor windings, so this electrically connects the motor lead to the windings. An insulator is positioned to electrically isolate the motor housing terminal from the housing itself.

A high voltage connector, connected to a device, that experiences a reduced electromagnetic interference (EMI), avoids galvanic corrosion of dissimilar metals within or without a fluid environment, and provides an effective electrical ground system. The connector includes an outer housing assembly, an inner housing mounted inside the outer housing, a set of cable reinforcement retainer assemblies secured inside the inner housing, a back cover through which the cables respectively slide along and covers a central opening of the outer housing, a braided shield covering the cables, and a clamp that connects the shield onto the outer housing. When assembling the high voltage connector, the outer housing is mounted onto the device; the inner housing is secured inside the outer housing; the set of cable reinforcement retainer assemblies with associated cables is secured in and extends in a substantially vertical direction from the inner housing; a back cover is slid along the cables, and enters and covers a central opening of the outer housing; and a braided shield is mounted and connected to the outer housing by a clamp.

Various embodiments provide a stackable deformable electrical connector system including a plug body and a connector body each having at least one of studs and jacks with angled and/or misaligned axes. A deformation of one or more of a plug body, studs, jacks, and a connector body or another stackable connector is created when plugging together the angled studs and jacks. The deformation creates resultant forces between the studs and jacks for electrical contact. The connectors may integrate deformable bars in the connector body, locking features and features to ensure polarity. The studs and jacks may be solid metal corrosive-resistant parts, such as titanium, Hastelloy, or Inconel.
