A housing includes a housing main body configured to be fitted with a mating housing, and a cover configured to be mounted to an end portion of the housing main body from which an electric wire is drawn out and to cover the electric wire drawn out from the housing main body. The housing main body includes a lock arm for locking a protruding portion of the mating housing, and a release arm that swings when an operation portion of the release arm is pressed to release a locking of the protruding portion and the lock arm. The cover has a lock piece that is interposed between the housing main body and the operation portion when the cover is mounted to the housing main body so as to restrict a swing of the release arm.

A connector includes a housing including a terminal accommodating chamber to accommodate a terminal, and a tubular portion to surround an insertion opening, through which the terminal enters the terminal accommodating chamber, the tubular portion including an opening portion, a water stop member to prevent water from passing through the insertion opening and a holding member to be inserted from the opening portion such that the water stop member is placed between the insertion opening and the holding member, the holding member retaining the water stop member inside the tubular portion. The holding member includes a projection on an outer surface of the holding member toward an inner peripheral surface of the tubular portion at an end portion of the holding member, the end portion is close to the opening portion of the tubular portion when the holding member is fitted in the tubular portion.

A connector assembly comprises a first connector and a second connector mateable with each other along a front-rear direction (X-direction). The first connector comprises a first inner structure and a first outer member having a first lock surface, a first regulation portion and a first abutment portion. The second connector comprises a second inner structure having a second abutment portion, and a second outer member having a second lock surface and a second regulation portion. The second abutment portion is brought into abutment with the first abutment portion when the second connector is mated with the first connector. Under a mated state where the first connector and the second connector are mated with each other, the second lock surface regulates a rearward movement of the second connector relative to the first connector, and the second regulation portion regulates a forward movement of the second connector relative to the first connector.

An electrical connector includes a shell and a coupling ring. The shell has contact receiving passages and an outer wall with a coupling ring retaining projection. The coupling ring is integrally mounted on the shell. The coupling ring is movable between a first position and a second position. A spring is integrally positioned on the coupling ring. The spring is provided in a stressed position when the coupling ring is moved to the second position. Openings are provided in the coupling ring; the openings being positioned proximate the spring. The opening are dimensioned to allow the removal of residual material produced during the manufacture of the electrical connector.

A male plug and a female receptacle and a docking structure thereof include a male plug and a female receptacle docked with each other. When the male plug and the female receptacle docked with each other, the male plug is fitted with the female receptacle using a horizontal holding force provided by a first fastening structure, and is fitted with the female receptacle using a vertical holding force provided by a second fastening structure, hence further reinforcing plugging stability between the male plug and the female receptacle by the horizontal and vertical holding forces.

A conductor connection terminal with an insulating material housing, wherein the insulating material housing has a mounting opening and a conductor insertion opening, with a closure part, wherein the closure part can be inserted into the mounting opening, with a contact insert, wherein the contact insert has a busbar and a clamping spring, the clamping spring with a clamping leg extending toward the busbar with a spring clamping edge for clamping an electrical conductor, and with a first latching connection arranged between the closure part and the insulating material housing, wherein the closure part and the insulating material housing can be fixed to one another by means of the first latching connection, wherein a second latching connection is arranged between the closure part and the contact insert, wherein the closure part and the contact insert can be latched together by the second latching connection.

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.

An optoelectronic module may include a housing enclosing at least one optical transmitter or receiver, and a slider configured to move with respect to the housing. The slider may include at least one protrusion configured to engage with a cage sized and shaped to receive the housing, and a retainer configured to engage both the slider and the housing to retain the slider with respect to the housing. The retainer may include a first protrusion sized and shaped to be positioned in a slot defined by the housing, and a second protrusion sized and shaped to abut the slider.

Disclosed herein is a connector cover configured to be used in an ultrasonic probe connector and an ultrasonic probe assembly. The connector cover includes a case, and a coupling device disposed at one end portion in the case and configured to be coupled to the connector. The coupling device includes a body including a fastening portion configured to be coupled to a connector protrusion provided to protrude from the connector toward a first direction, and a rotating shaft connected to the case and the body, and the connector cover is configured to be coupled to the connector along a second direction.
