A system comprising of a first adapter housing, with a first contact carrier received therein, a second adapter housing, with a second contact carrier received therein, and a top-hat rail is also provided.

Daughter card assembly including a circuit board and leading and trailing connectors mounted to the circuit board. The leading and trailing connectors have mating ends that face in different directions along a board plane. The daughter card assembly also includes a support wall that is coupled to the circuit board and extends orthogonal to the circuit board. The support wall has a wall opening therethrough. The trailing connector is positioned on the circuit board such that the mating end substantially aligns with the wall opening. The daughter card assembly also includes a retention shroud that projects from an exterior surface of the support wall. The retention shroud defines a shroud passage that aligns with the wall opening. The shroud and wall openings form a receiving passage for receiving at least one of the trailing connector or a corresponding cable connector that mates with the trailing connector.

A wire connection terminal structure includes a leaf spring, a conductive plate and a fixing frame framing and connecting with the leaf spring and the conductive plate. The conductive plate is formed with a base section assembled with the fixing frame. The leaf spring is formed with an elastic swingable holding section extending to a position in contact with the base section. The holding section and the base section define therebetween an elastic holding mouth. An external electrical wire can be plugged into the holding mouth and held between the holding section and the base section and electrically connected with the conductive plate. The conductive plate and the fixing frame are two separate components so that the conductive plate is solely made of a high-conductivity material, while the fixing frame is made of a material with higher structural rigidity.

A system for coding without compilation includes: a module assembly connected to a user terminal and a function information providing server through a network and including a plurality of modules; and a function information providing server including a function information reception unit receiving function information from the plurality of modules, a function action order generation unit generating a total sequence for a function action order based on the function information, and a function action information transmission unit transferring a command word to the module based on the function action order, in which the command word includes at least one of unique information of a next module relayed next to the module which operates based on the function action order and function number type function information to be executed in the next module, and the command word is sequentially transferred to the module relayed based on the function action order.

A wiring adapter is provided which controls the shear point for a wiring system in a traffic control box and other electrical panels. The wiring adapter includes a bottom segment which is securely mounted in the control box. Incoming wires to the control box are connected to the bottom segment. The top segment of the wiring adapter includes connections for wires running from the wiring adapter to the power or control elements in the control box. The wiring adapter uses a quick release retention mechanism to secure the top segment to the bottom segment. When a triggering event occurs, the quick release mechanism separates the top segment from the bottom segment to ensure that the shear point for the wiring system occurs at the wiring adapter.

A tool-less terminal block includes an insulated base, a turning part, a conductive terminal and a spring clamp. The insulated base has a cavity and a slot communicating to the cavity; the turning part is pivotally coupled to the insulated base; the conductive terminal is fixed to the bottom of the slot; the spring clamp is accommodated in the cavity and disposed at the top of the conductive terminal, and the spring clamp has a movable elastic arm pressing the conductive terminal to seal the slot, and the movable elastic arm has a link rod fixed to the turning part and operable together with the turning part. When the turning part is turned to a released position, the link rod is pulled by the turning part to drive the movable elastic arm away from the conductive terminal to open the slot, so as to provide a convenient use.

A conductor terminal for connecting at least one electrical conductor. The conductor terminal has a base module which includes mounting rail fastening elements for fastening the conductor terminal to a mounting rail. The base module includes a housing, which extends in its longitudinal direction up to two end areas of the housing. A central area of the housing is provided between the two end areas, with the central area projecting beyond the two end areas in a direction facing away from the mounting rail fastening elements. The base module also includes at least one receptacle arrangement being disposed on the base module in each of the two end areas, each for accommodating a conductor connecting module. The conductor connecting modules each include at least one conductor terminal connection designed to connect an electric conductor.

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 locking structure includes: a locking protrusion and a locking arm. The locking arm includes a flexible arm main body and an engaging projection portion protruding from an outer surface of the arm main body. The locking protrusion includes a protrusion main body on which an arm guide surface, a protruding tip surface, and an engaging surface are disposed along the engagement direction, and a jig groove that is formed in the protrusion main body. The engaging projection portion is formed on the outer surface at a position away from an arm tip of the arm main body in the engagement direction. The protruding tip surface is longer than the arm tip in the engagement direction. The jig groove cuts out the protrusion main body in the engagement direction from the arm guide surface to the protruding tip surface.
