A plug connector comprises a first plug, a second plug, and a securing device configured to mechanically secure the first plug to the second plug. The second plug has a receptacle with a ramp surface and a locking surface. The securing device has a lever pivotably mounted on the first plug. The lever pivotably bears a connecting element which has a securing cam on a free end of the connecting element. The receptacle of the second plug receives the securing cam and the ramp surface of the receptacle cooperates with the free end of the connecting element to forcibly guide the securing cam behind the locking surface of the receptacle when the first plug and the second plug are plugged together.

A lever 30 includes two arms (31), a coupling (32) coupling base ends (31R) of the arms (31) and an operating portion (33) coupling tips (31F) of the arms (31). The lever (30) is supported rotatably on a housing (10) with rotary shafts (34) formed on the coupling (32) serving as a fulcrum. Two sliders (40) are mounted in the housing (10) while being fit to drive shafts (38) of the lever (30) and slide in conjunction with the rotation of the lever (30). The sliders (40) are formed with cam grooves (43) configured so that cam followers (53) of a mating housing (51) slide in contact with the cam grooves (43) as the sliders (40) are slid.

A connector fitting structure of a first connector and a second connector that are to be fitted and electrically connected to each other is provided. The first connector includes: a first housing that accommodates a first connection terminal; and a guide groove that is provided in the first housing. The second connector includes: a second housing that accommodates a second connection terminal; a guide protrusion portion that is provided at the second housing and is inserted into the guide groove; and a guide protection portion configured to be displaced between a covered position where the guide protection portion covers the guide protrusion portion and an exposed position where the guide protection portion does not cover the guide protrusion portion.

A connector comprises a first housing, a cam member, and an operation lever. The first housing has a mating portion configured to mate with a second housing of a second connector. The cam member has a cam groove configured to mate with a cam pin provided on the second housing. The cam member causes the second housing to mate with the first housing by sliding in a lateral direction intersecting with a direction of mating to draw the cam pin into the cam groove. The operation lever slides the cam member according to a turning operation. A nipping portion of the connector nips the cam pin in the cam groove when the cam member slides up to a mating completion position at which mating of the second housing with the first housing is completed.

The invention relates generally to a lockable socket. In one example embodiment, to methods, apparatus, and systems to a safe electrical socket, wherein the socket may lock such that the plug, wires or connectors may not be accidently or forcibly removed without activation or deactivation of the locking structures. The locking mechanism may include a cam like actuator and locking mechanism that provides a secure and strong mechanism.

The present disclosure provides an electrical connection system that comprises a first electrical connection component that is suitable for transmission of power with a voltage level greater than 0.5 k V and is arranged for coupling to a second electrical connection component suitable for transmission of power with a voltage level greater than 0.5 k V. Further, the electrical connection system comprises a mechanical coupling assembly that has first and second portions. The first portion is removeably engageable with the first electrical connection component and the second portion is removeably engageable with the second electrical connection component. The mechanical coupling assembly is structured to drive the first electrical connection component and the second electrical connection component relative to each other along a central axis of the electrical connection system and between disengaged and engaged conditions.

An electrical connection system is described. The electrical connection system comprises a first electrical connection component that is suitable for transmission of power with a voltage level greater than 1 kV. The electrical connection system also comprises a second electrical connection component that is suitable for transmission of power with a voltage level greater than 1 kV and arranged for coupling to the first electrical connection component. The electrical connection system comprises a mechanical coupling assembly for imparting a driving force to drive the first and second electrical connection components relative to each other along a central axis of the electrical connection system and between disengaged and engaged conditions. The mechanical coupling assembly is structured to impart a portion of the driving force at a first eccentric position and comprising a transmission that is arranged to transmit a further portion of the driving force to a second eccentric position. The second eccentric position has an angular orientation around the central axis that is different to that of the first eccentric position.

A board mount electrical connector (3) includes an insulative connector housing (1100) including a longitudinal bottom wall (1102) defining a plurality of contact openings (1104) for receiving a plurality of contacts (1200), first and second side walls (1106, 1108) extending upwardly from the bottom wall at opposing sides thereof, first and second end walls (1110, 1112) extending upwardly from the bottom wall at opposing ends (1102c, 1102d) thereof, first and second pairs of latch openings (1114, 1116) at opposing ends of the bottom wall, and first and second protrusions (1154, 1156) extending upwardly from the bottom wall and disposed between respective first and second pairs of latch openings. Each latch opening extends through the bottom wall and through a side wall and is configured to allow a latch to eject a mating connector by moving within the opening. Each of the protrusions is configured to engage a corresponding opening in a latch of a mating connector cover or strain relief assembled to the electrical connector.

A waterproof connector (1) includes an accommodation recess (31) formed in a wire draw-out surface (26) of a housing (10) and configured to accommodate a ventilation film (63). A wire cover (50) is mounted on the housing (10) to cover the wire draw-out surface (26) and the accommodation recess (31). A wire bending space (54) inside the wire cover (50) is configured to bend wires (15) drawn out from the wire draw-out surface (26). A partition (56) is formed in the wire cover (50) and partitions between the accommodation recess (31) and the wire bending space (54) by contacting the wire draw-out surface (26) to cover an opening of the accommodation recess (31). Drainage portions (37, 38, 39, 40) are formed in a contact area between the wire draw-out surface (26) and the partition (56) and has a convexo-concave or stepped cross-sectional shape.
