An electrical connector assembly having a female member and a male member is provided. The female member includes: a peripheral wall formed in an annular shape to define a first interior space; a plurality of exterior walls each formed in a semi-annular shape to define a plurality of second interior spaces located outwardly of the first interior space. In particular, the peripheral wall includes a plurality of slots corresponding to the plurality of exterior walls, and the plurality of slots communicates the first interior space with the plurality of second interior spaces. The male member includes a plurality of partition walls sized to be received by corresponding second interior spaces and slots whereby the partition walls separate the first interior space into corresponding chambers for each electrical prong of the male member.

A connector 20 to be fit into an open receptacle 13 of a male connector 10 includes a terminal 25 connected to an end part of a wire 22, and a housing 40 for holding the terminal 25. The housing 40 includes a lead-out portion 54 for leading out the wire 22 connected to the terminal 25 to outside, a protruding portion 46 protruding outward to face a tip part of the receptacle 13, an external fitting portion 50 projecting from the protruding portion 46 toward the receptacle 13 to be externally fit to the tip part of the receptacle 13 and expose an outer surface of a base end side of the receptacle 13, and a reinforcing rib 60A, 60B connected to the lead-out portion 54 and the protruding portion 46.

Connectors having contacts that can be highly corrosion resistant, can conserve precious materials, and can be readily manufactured. Examples can provide connector contacts that are highly corrosion resistant. These contacts can be formed of a precious metal or a precious-metal alloy. The precious-metal alloy can be a high-entropy alloy. To conserve the precious materials, a contact can be formed by a stamping a structure that becomes the contact, instead of stamping the contact from a structure. The structure can be a rod. To conserve the precious materials, only contacts that convey high voltages, such as power supplies, might be formed of the precious materials.

A current detector includes: a printed circuit board; and a resistor for detecting an electric current of the electrochemical device, wherein a connector having a first terminal is mounted on the printed circuit board, and the resistor has a second terminal which is brought into contact with the first terminal.

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 technique facilitates construction of a sealed electrical connector, e.g. sealed pothead assembly. Depending on the application, the electrical connector may be used to connect a power cable and a powered component such as an electric submersible pumping system. The electrical connector comprises at least one connector component and at least one electrical component. An injection molding process is used to construct an injection molded feature sealed to a corresponding component, e.g. to the at least one electrical component. The injection molded feature is readily formed and located between the at least one electrical component and the at least one connector component to form a simple and reliable seal which prevents unwanted passage of fluids.

A connector includes a terminal configured to electrically connect to an insertable and removable connection target, a housing configured to accommodate the terminal, and a retainer configured to fit into the housing in which the terminal is accommodated. The terminal includes a base end portion provided with an electric cable connection portion (flexible wiring member connection portion) configured to connect to an electric cable (flexible wiring member), a leading end portion provided with a contact portion configured to contact a connection target, and a spring portion positioned between the base end portion and the leading end portion. When the retainer is in a state fitted to the housing, the base end portion is movable with respect to the housing within a predetermined movable region in a connector front-rear direction that is an insertion/removal direction of the connection target.
