It is aimed to provide a connector capable of dealing with a change in the number of poles without structurally changing a mating connector. Housings (11) for accommodating terminal fittings (12) electrically connectable to tab-like terminals (52) include a main housing (11M) having a locking structure (21) for locking a mating connector (52) and a plurality of types of sub-housings (11S) having different number of poles and selectively unitable with the main housing (11M). The main housing (11M) and the sub-housing (11S) are united by coupling side surfaces to each other. A tab insertion groove (25) into which the tab-like terminal (52) is to be inserted at the time of connection to the mating connector is formed in a coupling part of the united housings (11).

An electrical connector includes contact pins, insulating housings for containing the contact pins therein and metallic outer contacts for respectively covering the housings. Each of the contact pins includes a horizontally extending portion, a contact portion, a connection portion, a downwardly extending portion and a press-fitting shoulder extending from a side portion of a base end portion of the horizontally extending portion in a width direction thereof. A width of the press-fitting shoulder of each of the contact pins decreases from a base side toward a tip side.

A module connector includes a first connection part and a second connection part that can be electrically conductively connected with the first connection part. The first connection part has a first attachment element and the second connection part has a second attachment element; the first attachment element can be inserted into the second attachment element. Each of the first connection part and the second connection part has a contact protection at a side facing the other connection part. The contact protection has an outer electrically insulating collar and an electrically insulating protection pin surrounded by the outer electrically insulating collar. At least one of the first connection part and the second connection part has a current bridge between the outer electrically insulating collar and the electrically insulating protection pin. The outer electrically insulating collar and the electrically insulating protection pin extend beyond the current bridge.

A plug-in connector part for plug-in connection to a mating plug-in connector part includes: a housing part which has at least one receiving opening and at least one electrical contact element disposed in the at least one receiving opening; and a staking element arranged on the housing part and which in a preassembled state of the connector part is movable along a staking direction to the housing part and by moving in the staking direction is brought into interaction with a staking section of the housing part so that, in an assembled state, the at least one electrical contact element is staked to the housing part.

Systems, devices, and methods including: a cable; a housing having a tapered exit hole connected to an internal volume; a tapered seal having a tapered outer surface and an inner aperture, where the inner aperture of the tapered seal receives the cable; an encapsulant disposed in the internal volume and about one or more wires of the cable; and a compression cap placed over the tapered seal and about a flange of the housing to compress the tapered seal into the tapered exit hole; where compression from the compression cap forces the encapsulant up inside the cable and around the one or more wires of the cable, and where curing of the encapsulant seals the cable from moisture incursion.

A connector includes a housing having a lock portion to be engaged with a mating housing when the housing is fitted with the mating housing, and a fitting-ensuring component mounted on the housing and configured to detect whether the housing and the mating housing are fitted with each other by avoiding interference with the lock portion and being movable to a predetermined mounting position when the housing and the mating housing are fitted with each other. The lock portion and the fitting-ensuring component are configured that at least a part of one of the lock portion and the fitting-ensuring component enters a recess of the other of the lock portion and the fitting-ensuring component so as to extend a movable range of the lock portion when the lock portion is operated so as to release engagement between the lock portion and the mating housing.

A connector for exactly two conductors that includes a forward connector body, a rear connector body, a metal frame and exactly one pair of electrical contacts. The rear connector body interfaces with the forward connector body. The metal frame surrounds at least a portion of both the forward connector body and the rear connector body. The metal frame including a shielding interface, wherein the metal frame is secured to the forward connector body with at least two retaining features. The exactly one pair of electrical contacts comprises a first electrical contact and a second electrical contact that extend from the rear connector body into the forward connector body.

An electric connection member including: a bus bar that has at least one terminal portion; a primary molded portion formed in one piece with the bus bar in a state where the terminal portion is exposed; a secondary molded portion formed in one piece with the primary molded portion; and a seal member embedded in the secondary molded portion, wherein the primary molded portion includes an exposed portion that is exposed from an opening portion provided in the secondary molded portion, the seal member is shaped to surround the circumference of the exposed portion without a gap, and a boundary portion of the seal member to the secondary molded portion is heat sealed to the secondary molded portion.

An electrical cable connecting system includes a modular electrical or electronic wiring device assembly, in which an electrical or electronic wiring device and a connector may be electrically coupled via pig-tail jumper electrical wires. The connector may be coupled to cable electrical wires fitted with a cable protector to protect the electrical wire conductors therein. The connector may include internal electrical terminals for electrically coupling building electrical cable wires with corresponding jumper electrical wires. The connector may be mechanically and electrically coupled to and directly terminate one or more building electrical cables, which may provide power to or from one or more electrical or electronic wiring devices by establishing an electrical pathway from a source of electrical power, through the building electrical cable wires, the connector, the pig-tail jumper electrical wires and an electrical or electronic wiring device.

A connector includes: a contact batch that is composed of two or more groups of contacts; an inner shield that electrically separates the two or more groups of contacts from each other; a body in which the contact batch and the inner shield are press-fitted and fixed; and a shell that covers the contact batch, the inner shield, and the body.
