A circular plug-in connector for establishing a shielded plug-in connection to a mating plug-in connector includes: a contact carrier having at least one electrical contact element; a shielding sleeve that surrounds the contact carrier at least in part; and a screw housing that is rotatably connected to the shielding sleeve and adapted to screw the circular plug-in connector to the mating plug-in connector. A connection portion of the shielding sleeve is received in a receiving space of the screw housing The circular plug-in connector provides shielded contact between the screw housing and the shielding sleeve. The shielding sleeve includes a collar in the connection portion. The circular plug-in connector further includes a stopper for closing a receiving opening of the receiving space at least in part, such that the collar is trapped in the receiving space.

A pluggable optical module may include a housing enclosing one or more optical components and one or more electrical components. The pluggable optical module may include a slider to move along an exterior wall of the housing in association with latching or unlatching the pluggable optical module. The pluggable optical module may include an electromagnetic interference (EMI) shield arranged in a gap between the slider and the exterior wall of the housing such that the EMI shield contacts the slider and the exterior wall of the housing. The EMI shield reduce EMI radiation passing through the gap.

A plug connector is provided which has a base body and a slide element, wherein the base body has a plug side and a connection side, wherein the plug connector forms a plug axis which extends from the plug side to the connection side through plug the connector, wherein the slide element surrounds the base body and is arranged on the same to be movable along the plug axis. The connector additionally has a securing element, wherein the securing element is arranged between the slide element and the connection side of the plug connector, and wherein the securing element is arranged on the base body to be movable between an open position and a locked position.

A flexible and/or stretchable structural system for transmitting electrical signal between first and second rigid portions comprises a body structure and said first and second portions arranged to said body structure. The modulus of elasticity of said first portion is lower than the corresponding modulus of elasticity of said second portion. In addition the modulus of elasticity of said body structure is lower than the corresponding modulus of elasticity of said second portion. The system comprises also an interface portion, such as e.g. an electrically conducting fabric, textile or knit, which is arranged to said body structure and between said first and second portions. The interface portion electrically connects said first and second portions. The modulus of elasticity of said interface portion is lower than the corresponding modulus of elasticity of said second portion.

A connector includes a first housing (10) and a second housing (60) connectable to each other. The second housing (60) includes two walls (64) facing each other. The first housing (10) includes a receptacle (12) defining a fitting space (14), two side walls (19) connected to both circumferential ends of the receptacle (12) and a lock arm (24) arranged between the side walls (19). Entrance spaces (29) into which the walls (64) enter are defined between the side walls (19) and the lock arm (24) to communicate with the fitting space (14). Protrusions (31, 32) configured to contact the walls (64) are provided on inner surfaces of the side walls (19).

An electrical connector includes an insulation body, a seat, and a positioning plug. The seat is disposed on an outer peripheral surface of the insulation body. The seat includes a tunnel defined through the seat to form an inlet and an outlet. The outlet and a front surface of the insulation body face the same side. The seat further includes a slit and one or more first bumps disposed on an inner wall of the slit. The positioning plug includes a sliding block and rib. The sliding block movably disposed in the tunnel via the inlet with the rib movably disposed in the slit. The positioning plug further includes a second bump disposed on a lateral side of the rib facing the first bump. When the sliding block moves to an installation position, the first bump stops the second bump to fix the sliding block at the installation position.
