The lever includes a cam plate portion. A cam groove to be engaged with a cam pin provided on the mating connector is provided to penetrate through the cam plate portion. A reinforcing rib is provided to cover the cam pin and extend over the cam groove near an entrance opening of the cam groove, into which the cam pin enters. The connector housing includes lever protection walls. The lever protection walls are provided to project from both side walls of the connector housing to come into contact with an outer edge part of the cam plate portion located outside the cam groove with respect to a rotary shaft when the lever is at the connection start position.

A connector 1 includes: a connector housing 10 that includes a housing main body 10A that can be fitted to a mating connector 60, and a CPA holding portion 21 that is disposed on an outer surface of the housing main body 10A; a CPA member 40 that is attached to the CPA holding portion 21, and that can be moved from a standby position to a fitting assurance position when the housing main body 10A is in a fitting complete position relative to the mating connector 60; and a two-dimensional code 50 that is disposed on the outer surface of the housing main body 10A. A part of the two-dimensional code 50 is covered by the CPA member 40 when the CPA member 40 is in the standby position, and the entire two-dimensional code 50 is exposed when the CPA member 40 is in the fitting assurance position.

A position assurance apparatus, which is used for a connector assembly connected to a signal circuit are provided. The connector assembly comprises a first connector and a second connector, which are connected in pairs, wherein the first connector is connected to the signal circuit, and the second connector is inserted in the first connector. The position assurance apparatus comprises a first connecting portion and a second connecting portion, which are electrically connected to each other. The first connecting portion and the second connecting portion are configured to be electrically connected to the signal circuit by means of the first connector, so as to turn on the signal circuit when the first connector and the second connector are inserted in place.

A lever of a connector can rotate between a first position and a second position and can slide between the second position and a third position. When the lever is rotated to the second position in a state in which the connector whose lever is on the first position is on a fitting preparation position with respect to a mating connector, the connector is drawn to a fitting position, which is closer to the mating connector, by a cam mechanism and a main terminal of the connector and a mating main terminal of the mating connector are connected with each other. When the lever is slid to the third position, a flange portion provided to a housing of the connector and a mating flange portion provided to a mating housing of the mating connector are accommodated in a groove portion of the lever.

A connector assembly comprises a first connector including a first connector body, and a shaft connected to the first connector body. A lever is rotatably connected to the shaft and is selectively fixable to the first connector body in a caught state. A second connector of the assembly includes a second connector body insertable into the first connector body, a releasing element defined on the second connector body for releasing the lever from the caught state, and a biasing element defined on the second connector body for rotating the lever after being released from the caught state.

A connector with an interlock housing, to which an interlock terminal is attached, separately from a lever that performs connection and disconnection of main terminals with a mating connector, and a first spring piece is formed on the lever. After the main terminals are mutually connected by rotating the lever from a first position to a second position, the lever is slid from the second position to a third position and the interlock housing is pushed down from an opening position to a closing position. When the lever is on the third position and the interlock housing is on the opening position, the first spring piece generates a first elastic restoring force. When applying no external force that slides the lever to the third position against the first elastic restoring force, the lever moves away from the third position and the interlock housing cannot be pushed down.

A power tool including a housing that has a battery pack receiving portion configured to receive an interface of a battery pack, device contacts extending from the housing and configured to mechanically and electrically engage with the battery pack, and a latching mechanism supported by the housing and including an actuator and a latch member configured to selectively engage the interface of the battery pack. The actuator is pivotable to operatively pivot the latch member.

Provided is a connector including first and second connector members connected to each other. The first connector member is formed with a protrusion. The second connector member includes a lever member rotatably provided thereto. The lever member is formed with at least one claw-shaped part configured to lock the protrusion. When connecting the first and second connector members, the lever member is rotated so that the protrusion locked in the claw-shaped part of the lever member is drawn in a connecting direction, and the first and second connector members are moved in the connecting direction and brought into contact with each other. After the movement is restrained, the lever member is further rotated so that the lever member is fixed while being elastically deformed.

An electrical connector has a connector housing, a securing element and an actuating element movable between a home position and a locking position and which is designed to lock the electrical connector with a corresponding electrical counterpart connector. The connector housing has a locking guide for guiding the securing element between an initial position, and a securing position, wherein the securing element engages with the actuating element so that the actuating element is locked in the locking position. The securing element has a latching tab and the locking guide has a first stop for the latching tab to block the securing element in the initial position. The actuating element has a releasing body which penetrates into a recess in the locking guide to displace the latching tab of the securing element, to release the securing element.

A connector assembly enables electrically safe disconnection and separation because it is possible to secure an interval between the point of time of separation of interlock terminals and the point of time of separation of power terminals when connectors are separated. The connector assembly can implement two steps of cutting power after restricting a lever in a locked state and then completely disconnecting connectors by additionally operating the lever by including an intermediate locking mechanism that restricts the lever for disconnecting connectors in a state in which interlock terminals of two connectors are separated from each other but power terminals of the two connectors are in contact with each other to disconnect and separate female and male connectors.
