A connector with at least one guiding portion is provided along with a shell and an insulating body of the connector. The connector includes a plurality of metal terminals in addition to the insulating body and the shell. The metal terminals are fixedly provided in the insulating body. The insulating body is mounted in the shell, and the connector is characterized in that at least one plate-shaped guiding portion extends upward from a portion of the top edge of either the shell or the insulating body. While another connector is being connected to or disconnected from the connector, the guiding portion guides the another connector to facilitate electrical connection with or detachment from the connector.

Systems and methods of deploying seismic data acquisition units from a marine vessel are disclosed. The system can include a mechanical attachment device comprising a cavity formed by interlocking a first member and a second member. Protrusions located on the first member and second member can increase the coefficient of friction between a rope and the mechanical attachment device responsive to an increase in tension on the rope. A lanyard can couple a seismic data acquisition unit to the mechanical attachment device.

A connector (10) includes a housing (12) to which a mating housing (82) is to be connected from front, side walls (56) constituting an outer surface of the housing (12) and adjacent to upper and lower surfaces via corners (59), and steps (62) provided from the side walls (56) to the corners (59) and becoming gradually thicker in a vertical direction and a lateral direction toward a front side.

An electrical connector comprises a first housing member that engages a second housing member engages to form an enclosure. In the enclosure, a substrate supports a central set of conductive members in a second tubular portion. A first arm is pivotably attached to the second housing member. The first arm is resiliently biased inwardly toward the second base portion. A second arm is pivotably attached to the second housing member and spaced apart from the first arm. The second arm is resiliently biased inwardly toward the second base portion. In accordance with one aspect, the arms support automatic latching of the connector portion to a mating connector.

A connector set includes: a first connector having a first housing; a second connector having a second housing; and a slide member slidably held in one of the housing. An engaging part is formed on the slide member, the engaging part being locked to a locked part formed on the other housing to restrict the sliding of the slide member to the first position when the slide member is slid to the second position. The locked part is formed on the housing main body of the other housing.

A moving plate (13) is inserted into a receptacle (11) of a connector body (12) and movable between a partial locking position and a connection position and includes partial locking portions (91) and resilient locking pieces (46). The partial locking portions (91) restrict movement of the moving plate (13) to the connection position. The resilient locking pieces (46) lock to receiving portions (75) of a mating connector (60) and allow movement from the connection position to the partial locking position by being kept locked to the receiving portions (75) while separating the mating connector from the receptacle (11). The connector body (12) has restricting surfaces (28) to restrict deflection of the resilient locking pieces (46) until a riding amount of the partial locking portions (91) on second interfering portions (36) is a maximum when the moving plate (13) returns from the connection position to the partial locking position.

Disclosed herein is an air cleaner capable of being coupled or separated in a vertical direction to improve space utilization. An air cleaner may include a first air cleaning module provided with a first connection unit, and a second air cleaning module detachably coupled to the first air cleaning module and provided with a second connection unit, wherein the second connection unit is configured to be detachably coupled to the first connection unit, and configured to be rotatable with respect to the first connection unit when the second connection unit is coupled to the first connection unit.

A foolproof electrical connector interface system includes a connector male, a connector female, two fixing plates and two junction boxes. The connector male and the connector female are fixed in installing slots of a photovoltaic panel; the fixing plates are provided with positioning columns, first hooks and second hooks; the fixing plates are connected with the photovoltaic panel, and then the connector male and the connector female are respectively fixed between the first hooks and between the second hooks; the connector male and the connector female are electrically connected by a wire; the connector male is provided with a male plug; the male plug is provided with a bump; the connector female is provided with a female plug; the female plug is provided with a groove; the junction boxes are waterproof junction boxes; the junction boxes are respectively electrically connected with the connector male and the connector female through wire.

A plurality of plug side connectors are prevented from moving relative to each other in the connecting/disconnecting direction with respect to the device side connector, and one of the plug side connectors can be individually disconnected from the device side connector. The connector structure includes a longitudinal movement restricting protrusion (54) provided on one of laterally facing side surfaces of the moveable member which is resiliently deformably provided on the plug side housing (32), and a pair of stopper portions (56, 58) provided on another of the laterally facing side surfaces of the piece (48), and configured to restrict a movement of the longitudinal movement restricting protrusion (54) of the laterally adjoining second housing (32) in the longitudinal direction by aligning with the longitudinal movement restricting protrusion (54) with respect to the longitudinal direction. When in an unlocked state in which the plug side connector (30) can be pulled out of the device side connector (10), the longitudinal movement restricting protrusion (54) and the stopper portions (56, 58) are placed out of alignment with each other to release the restriction of the movement in the longitudinal direction.
