A first connector and a second connector of this connector assembly can mutually connect along the vertical direction. The first connector comprises a first housing provided with a sliding surface, a locking surface, and a receiving surface. The locking surface intersects, at an angle of 90° or less, with a line segment extending straight upward from the locking surface. The second connector comprises a second housing provided with a spring section and a locked section. The locked section can move forward and backward as the spring section elastically deforms. The locked section has a locked surface. When the second connector is in a separated state of being separated from the first connector, the locked surface intersects, at an angle of 90° or less, with a line segment extending straight upward from the locked surface. In a fitting step, the locked section moves downward while being pressed against the sliding surface. The locked section abuts the receiving surface upon moving downward on the sliding surface.

A plug connector pluggable together with a counter connector includes a connector housing having a guiding member and a lever device. The lever device has a lever transferrable from a plug position to a securing position, a coupling that is movable by the lever to engage the counter connector, and a lever extension attached to the lever and extendable and/or retractable with respect to the lever. A swivel movement of the lever out of the securing position is blocked by the lever extension retracted with respect to the lever. The guiding member blocks a shifting of the lever extension if the lever is moved out of the plug position and is not in the securing position.

In an electric work vehicle, a power feeding assembly which connects a battery device to a power controller unit so as to feed power includes a fixed connector which is fixed to the battery device and electrically connected to the battery device, a cable harness connected to a power controller unit, and a free connector which is connected to an end of the cable harness and connectable to a fixed connector, and a connecting operation tool is configured to be movable the free connector between the connecting position in which the free connector is connected to the fixed connector and the detaching position.

A lever mechanism for sealing a telecommunications closure includes a plurality of hinge elements; a leveraging element extending upwardly from each hinge element; an arm section extending from the leveraging element; a biasing element downwardly extending from the arm section; and a handle coupled to the biasing element such that upon application of a compressive force to at least a portion of the handle, each hinge element, each leveraging element, each arm section, and each biasing element moves, allowing the lever mechanism to change from a non-actuated position to an actuated position. The lever mechanism is further configured to couple with a spring-activated element and environmentally seal the telecommunications closure.

The present invention provides a solid-state hard disk lug-in device, including: a main body; a solid-state hard disk installation slot arranged on one side of the main body; and plug-in components. The plug-in components include an operating switch and an operating handle. When the operating switch is closed, the operating handle is restricted to a closed position, and when the operating switch is open, the operating handle is released to an extended position; when the operating handle in the closed position is pushed by an external force, the solid-state hard disk can be inserted into the hard disk slot of the solid-state hard disk system; when the operating handle in the extended position is pulled by an external force, the solid-state hard disk can be pulled out of the hard disk slot.

A lever-type connector has a male housing (10) including a bottom wall (11) formed with through hole (23, 24) and a receptacle (12) extending forward from an outer periphery of the bottom wall (11). A female housing (30) is capable of fitting into the receptacle (12). A lever (33) is mounted on the female housing (30) and connects the male and female housings (10, 30) by being rotated from an initial position to a connection position. An arm (36) of the lever (33) is between an outer surface of the female housing (30) and an inner surface of the receptacle (12). First and second closing portions (40, 41) are on the arm (36) and are configured to close a clearance between an upper opening (13) of the receptacle (12) and the lever (33) by being above the through holes (23, 24) with the lever (33) at the connection position.

A method for latching an electrical connector includes aligning a connector with an inlet. A first surface of the connector is within a first distance of a second surface of the inlet. A puller arm of the connector is extended into the inlet to a second distance from the second surface of the inlet. The puller arm includes a gripping element configured to apply a first compressive force against the inlet. The puller arm is retracted relative to the connector while applying the first compressive force against the inlet. The puller arm remains in the inlet at the second distance, thereby inserting a first electrode of the connector into the inlet to connect the first electrode with a second electrode of the inlet. The first electrode transfers power to the second electrode from a high-power supply.
