A swivelling lever arrangement (3) for securing a housing arrangement (1) has at least of a first and a second housing part (11,12). The swivelling lever arrangement (3) has at least one swivelling lever (4) and a guiding pin (2). The swivelling lever (4) has a receptacle (8). The swivelling lever (4) and the guiding pin (2) are attachable on the housing parts (11,12) such that, when the swivelling lever (4) swivels from a release position into a locking position when the housing parts (11,12) are substantially brought together, the guiding pin (2) is receivable in the receptacle (8). The receptacle (8) has at least one cam (74) designed such that, when the swivelling lever (4) swivels, the guiding pin (2) is guided into a depth (84) of the receptacle (8) via the cam (74) such that part of the head portion (41) is deflected by the cam (74).

A connector includes a housing and a lock arm that extends from the housing and is engageable with a counterpart connector. The lock arm includes a first arm a has a shape of a cantilever beam and has a locking hole for being engaged with the counterpart connector at a free end side of the first arm, and a second arm that extends from an end portion on the free end side of the first arm and is capable of releasing the engagement by bending the first arm around a fixing end of the first arm. The locking hole has a hole of which the size in a width direction orthogonal to an extending direction of the first arm becomes larger as a measurement position of the size of the hole gets closer to the free end from the fixing end.

A lever assembly for mounting to a removable plug-in module for selectively engaging a lip of a rack for effecting an injection of the plug-in module into the rack, and related kit(s) and method(s). The lever assembly includes a lever handle, an elastic bias element mounted to the lever handle, a pivot arm pivotally mounted to the lever handle, a pawl pivotally mounted to the lever handle, and a pivot axle. The pivot arm and the pawl abut one another so that a rotational force applied to a forward free end of the pivot arm, urging the pivot arm to rotate away from a lower interior surface of the lever handle, is transmitted to the pawl so that a rearward tip of the pawl is urged to rotate upward.

A circuit card assembly for a communication system includes a PCB having a slot receiving a second PCB of a second circuit card assembly in a board loading direction. An electrical connector is mounted to the PCB having a receptacle housing and a mating housing movable within the receptacle housing in a connector loading direction along a connector loading axis parallel to the board loading direction. The mating housing is movable in the receptacle housing in a connector mating direction along a connector mating axis perpendicular to the connector loading axis. Contacts of the electrical connector are mated with contacts of the second electrical connector in a contact mating direction parallel to the connector mating axis.

A first connector has the rockable lever for engaging with a second connector. The lever has a working part, the operating part, and the regulating part. When a second connector is pressed downward toward the first connector, the working part is pressed by the second connector. As a result, the lever rocks and the regulating part regulates the upward movement of the second connector. At this time, the operating part moves upward. When an operator subsequently presses the operating part downward, the lever rocks in the opposite direction, and the regulating part allows the second connector to move upward. At this time, the first working part moves upward thus pressing the second connector upward.

A connector includes a connector body including an opening to which a substrate is to be inserted; guide posts provided at both sides of the connector body; and latches being rotatably connected to the guide posts, respectively, wherein each of the latches includes a lock plate configured to support the substrate from both surfaces of the substrate, when the substrate is inserted in the opening, and a presser configured to enter a notch provided at a side of the connector body.

The invention relates to a locking device for plug connector housings, wherein the locking device (1) can be mounted pivotably on a first plug connector housing (12), wherein the locking device (1) can be locked on a second plug connector housing (14), as a result of which the first and the second plug connector housings (12, 14) can be pressed resiliently against each other. The locking device has means which prevent inadvertent opening of a closed plug connection. This makes it possible to avoid machine failures and accidents. The invention also relates to a method for releasing a first plug connector housing (12) from a second plug connector housing (14) with a locking device (1) which is mounted pivotably on the first plug connector housing (12) and can be locked on the second plug connector housing (14), wherein a force required for a pivoting-open movement increases abruptly during the pivoting-open movement.

A printed circuit board (PCB)-mounted contactor including a PCB with planar surface, source and load terminals fixed to the PCB, and a contact. The contact is supported by the PCB and is movable between open and closed positions. Movement of the contact is parallel to the planar surface. Electrical assemblies having PCB-mounted contactors and methods of controlling current flow in electrical systems with PCB-mounted contactors are also described.

The present disclosure provides a connector structure (10) for secure installation, which is installed on a fixed plate (100) having a through hole (101). The connector structure (10) includes a connector housing (1), two elastic clamping arms (2), and two operable levers (3). The connector housing (1) is inserted through the through hole (101). The two elastic clamping arms (2) are extended from the connector housing (1) and arranged on two opposite sides of the connector housing (1). The two operable levers (3) are pivotally connected to the connector housing (1) and sandwiched between the connector housing (1) and the two elastic clamping arms (2). The two operable levers (3) include two inclined surfaces (31), which gradually increase in thickness (h), in a direction away from the through hole (101).

A connector assembly comprises a first connector and a second connector. The first connector comprises a first housing. The first housing is provided with an engaged portion. The second connector comprises a second housing, a lock lever and a spring. The second housing is provided with a first axis portion. The lock lever is provided with a second axis portion and an engaging portion. The engaging portion is positioned beyond the engaged portion in a first direction when the lock lever is positioned at a lock position under a mated state where the first connector and the second connector are mated with each other. The spring urges the lock lever to be moved toward the lock position. When the lock lever is positioned at the lock position, the spring urges the second axis portion to be moved in a second direction.
