An optical system includes a cage and an optical transceiver. The optical transceiver is inserted into the cage in a pluggable manner, and includes a housing, a partition component provided on the housing, and a fastening component movably disposed on the housing. The fastening component is detachably fastened with the cage. The partition component is located between the fastening component and the cage to separate at least a part of the fastening component from the cage.

Each of a first connector and a second connector of a connector assembly includes at least two high frequency signal terminals. When viewed from a first direction, each periphery of the high frequency signal terminals is surrounded by an outer shell and an inner shell. The outer shell has a substantially quadrilateral shape. The high frequency signal terminals, the outer shells surrounding peripheries of the high frequency signal terminals, and the inner shells, which are disposed on a second symmetry axis form a linearly symmetrical shape with the second symmetry axis as a center line of the outer shells along a second direction orthogonal to the first direction in which the high frequency signal terminals are arranged.

Various embodiments disclosed herein are directed to a Network system including: a connector comprising a housing comprising a groove running widthwise on a surface of the housing; and a push-pull tab comprising a complementary groove, wherein the push-pull tab is detachably connected to the housing; and a receiver device comprising one or more ports for receiving the connector, the one or more ports having an interchangeable anchor device including a first portion and a second portion; wherein the groove is configured to receive the first portion of the interchangeable anchor device when the connector is inserted into the receiving element, and wherein the complimentary groove is configured to receive the second portion of the interchangeable anchor device when the connector is inserted into the receiving element, the push-pull tab being configured to disengage the second portion of the interchangeable anchor device from the complementary groove when the push-pull tab is moved in a direction away from the connector, thereby disengaging the first portion of the interchangeable anchor device from the grove of the connector. Other aspects are described and claimed.

An arc prevention system including a jack having a receptacle, with the receptacle having an upper wall, a bottom wall, two opposing side walls and a back wall between the two opposing side walls, a sensor unit positioned on the back wall of the receptacle, where the sensor unit is positioned on the back wall of the receptacle such that the sensor unit engages a plug inserted into the receptacle.

The invention relates to a clamping device (5) for an electrical plug-in connection (1), which has a n electrical plug-in connector (2), an electrical mating plug-in connector (3) that can be electrically and mechanically connected to the plug-in connector (2), and a primary latching arrangement (4) for latching the connection between the plug-in connector (2) and the mating plug-in connector (3). Provision is made for the clamping device (5) to be designed to brace the plug-in connector (2) and the mating plug-in connector (3) relative to one another in a connected state in addition to the latching by way of the primary latching arrangement (4).

A connector is provided with a first housing, a second housing to be stacked on and coupled to the first housing and a mating housing to be connected to the first housing and the second housing. The mating housing includes a projecting portion to be arranged between first and second facing surfaces of the first housing and the second housing and capable of contacting the respective facing surfaces of the first housing and the second housing.

A cable connector includes a case, a fastener and an unlocking member. At least one side of the case has a texture area with a guide surface which is a smooth surface. The fastener is attached on the case and extended with a flexible arm. Part of the flexible arm is attached to the guide surface. The unlocking member includes a handle and a pushing block connected to the handle. The pushing block is sandwiched between the case and the flexible arm. When the unlocking member is pulled, the pushing block moves along the guide surface to separate the flexible arm from the case. When the unlocking member is released, the pushing block is pressed by the flexible arm to slide and return along the guide surface. The pushing block may return to original position without elasticity of a spring to simplify the structure and save the costs.

An electrical junction box includes: a first housing configured to hold a first terminal having a flat plate shape; a second terminal configured to allow the first terminal to be inserted thereinto such that the second terminal is conductively connected to the first terminal when the first terminal is inserted into the second terminal; and a second housing configured to be engaged with the first housing. The first housing has a first space defining, together with a second space of the second housing, a space configured to accommodate the second terminal. The first space is configured to accommodate a part of the first terminal. When the first housing is engaged with the second housing, the first terminal is allowed to be inserted into the second terminal such that the first terminal and the second terminal are conductively connected.

A manual oral care implement comprises a handle, a connector and a head, the head being repeatedly attachable to and detachable from the handle via the connector. The handle has a distal end and a proximal end opposite to the distal end and adjacent to the head when the head is attached to the handle. The proximal end has an upper surface that is at least partially chamfered. The handle has a longitudinal axis and a cross-sectional area extending substantially perpendicular to the longitudinal axis. The chamfered surface and the cross-sectional area define therebetween an angle α from about 15° to about 30°.
