An electrical pop out device has an shroud and a pop out housing configured to be inside the shroud in a retracted position and to extend outside the shroud in an extended position. A guidance mechanism connects the pop out housing with the shroud and allows movement of the pop out housing with respect to the shroud between a retracted position and an extended position. The electrical pop out device includes an electrical connection for powering an electrical/electronic device in the pop out housing and/or charging a battery of the electrical/electronic device in the pop out housing. The electrical pop out device may also include audio, video and/or data connections for the electrical/electronic device in the pop out housing. In some embodiments, the electrical/electronic device is portable and the pop out housing is detachable from the shroud.

This application discloses a coil spring type wire-locking terminal block, including a plurality of insulating seats arranged in sequence. A mounting groove is formed in each insulating seat. A wire inlet hole is formed in one side wall of the mounting groove. A connecting terminal is mounted at the bottom of the mounting groove, one end of the connecting terminal penetrates through the bottom of the mounting groove, and a first through hole is formed at one side of the connecting terminal. A wire locking frame is slidably connected in the mounting groove. A compression elastic member is arranged in the wire locking frame, and a second through hole is formed in the side wall of the wire locking frame. The wire inlet hole, the first through hole and the second through hole are arranged corresponding to each other.

A terminal block with a handle structure includes an insulation base having an accommodation space, an insertion port, and a side opening. The insulation base has a limit column and a pivot part formed in the accommodation space. A conductive terminal includes a conductive body and plural lead pins, and the conductive body is positioned in the accommodation space, and the lead pin passes out from the insulation base. An elastic plate includes an abutting arm with a curved surface, a bend section sheathing the limit column, and the abutting arm is suspended on a side of the insertion port, and a pivot of the handle structure is combined with the pivot part to make a handle protrude from the insulation base, and a pressing cam abuts against the curved surface of the abutting arm, so that the handle structure may avoid damages and provide a labor-saving effect.

A connecting terminal having a plurality of conductor connection modules, wherein the conductor connection modules each have an insulating material housing with a conductor insertion opening for receiving an electrical conductor. In each case two conductor connection modules arranged next to one another are connected via a web, wherein the web is designed flexibly in such a way that the conductor connection modules can be arranged from an initial position into an arrangement different from the initial position, and vice versa.

A spring force terminal such as a direct plug-in terminal for connecting a flexible stranded conductor includes a housing having a chamber and a plug-in channel for the conductor into the chamber. A busbar or a clamping cage are provided and a clamping spring arranged in the chamber acts as a compression spring for fixing the electrical conductor on the busbar or the clamping cage in the region of a clamping point. The clamping spring has a clamping leg pivotable around a pivot axis, which is adjustable from a latching state in which it is latched in a latching position into a clamping state in which it is unlatched from the latching position and presses the electrical conductor against the busbar or the clamping cage. The latching state is produced by pressing on the clamping leg in the conductor insertion direction using a pusher wherein the clamping leg is releasable from the latching state using two different actuatable adjustment devices. The second release element is designed to release the pusher from the latching position to release the clamping leg from the latching state. The release element is arranged and formed laterally in relation to the pusher in the chamber in such a way that it acts on the pusher essentially perpendicularly to the conductor insertion direction to release the pusher from the latching position.

A modular plug connector in a strip-shaped design can be plugged together with a corresponding mating plug connector such as a printed circuit board plug connector.
