A device includes a housing including a rail mount and a stopper to lock an engagement flange (RAb) on a DIN rail (RA) with the rail mount receiving the DIN rail (RA). A locking member is at a locking position to lock an engagement flange (RAb) on the DIN rail (RA) and at a release position to unlock the engagement flange (RAb) with the rail mount receiving the DIN rail (RA). A release button including a pressing portion to be pressed by a user is located in the housing with the pressing portion exposed outside the housing. An arm moves the locking member from the locking position to the release position in response to movement of the release button from a standby position to a pressed position deeper in the housing than the standby position.

DIN rail installation kit including main body, spring hook, latch fastener and elastic element and combined with electronic device. When latch fastener is pulled down first to move to second position, buckle of latch fastener pushes down on hook body of spring hook, and after passing under hook body, hook end of hook body can be temporarily positioned on side wall of latch fastener. When user releases latch fastener, elastic element returns latch fastener, buckle is then buckled on buckle portion of hook body, and second buckle means of latch fastener is kept away from first buckle means of main body to present a removable state. When latch fastener is pulled down secondarily to return to first position, buckle is separated from buckle portion of hook body, and second buckle means and first buckle means are relatively buckled on DIN rail to exhibit a state of tight coupling.

An I/O system having redundant removable and/or replaceable components. Each of the removable/replaceable components can be removed by displacement parallel to a common axis. An I/O device having an I/O base with a lock-out toggle to prevent installation of one or more I/O modules to the I/O base unless a ground screw has been secured to supporting structure.

A technique for exchanging signals between a control system (200) and at least two field devices (300) is described. One device aspect of the technique comprises a base (102) that comprises a control interface (104) and at least two slots (106). The control interface (104) is configured to connect (108.1) to at least two electrical line channels (108) of the control system (200) and the at least two slots (106) are each configured to detachably mechanically connect (106.1) to a module (110) and to pass (106.2) at least one of the line channels (108) to the respective module (110). Furthermore, the device comprises one or more modules (110), each of which comprises a base-side slot interface (112) and a field-side input and/or output interface, I/O interface, (114) different from the slot interface (112), wherein the slot interface (112) is configured for a detachable mechanical and electrical connection to one of the slots (106) of the base (102), and the I/O interface (114) is configured for a connection (116.1) to signal lines (116) of one of the field devices (300).

Provided in the present disclosure is a guiderail fixing structure. The guiderail fixing structure comprises: a housing; a transverse fixing component, arranged at the bottom part of the housing, being two mounting stands provided opposite each other, and used for implementing transverse fixing between a guiderail and the housing; and a vertical fixing component, arranged at the bottom part of the housing and within the two mounting stands provided opposite each other, and used for implementing vertical fixing between the guiderail and the housing. The vertical fixing component comprises engaging hooks and an engaging hook part. When the vertical fixing component is employed, the engaging hooks of the vertical fixing component used for engaging are arranged outside of either edge of the guiderail, and the engaging hook part of the vertical fixing component is arranged within the guiderail.

An electrical device includes: a first housing sub-assembly; a second housing sub-assembly that has a housing wall; and a locking device. The first housing sub-assembly and the second housing sub-assembly are positionable adjacent to one another along a plug-in direction and, when in a position in which they are adjacent to one another, are interlocked via the locking device. The locking device has an actuation element arranged on the second housing sub-assembly so as to be adjustable along an actuation direction, and a locking element connected adjustably to the housing wall and operatively connected to the actuation element. The locking element is configured, in the position of the housing sub-assemblies in which they are adjacent to one another, to interlock the first housing sub-assembly and the second housing sub-assembly, and, by moving the actuation element in the actuation direction towards the housing wall, are movable in an unblocking direction.

Described herein are radio tray assemblies that include space for a specific radio and its power supply and that additionally provide cooling and power conversion and control functionalities. The disclosed radio tray assemblies are designed to have a form factor compatible with legacy radio systems (e.g., MIDS-LVT) while enabling installation of a new radio system (e.g., MIDS-JTRS). The disclosed radio tray assemblies are configured so that the radio and its power supply are secured to a tray so that the radio and power supply are side-by-side and parallel lengthwise. A cooling module or assembly of the disclosed radio tray assemblies is disposed immediately behind the radio and its power supply and is configured to cool these units using forced air cooling directed lengthwise through the radio and its power supply. A power converter and controller module converts input power into the power required by the radio power supply.

This disclosure provides a field termination assembly (FTA) providing for ease of mounting to a support rail. The FTA provides a lever on a base that cushions against shocks and vibrations during shipment and operation while a housing is mounted on a base secured to a support rail. The base includes a dampener feature which makes it more capable of meeting operation and transportation vibration and shock requirements even for marine applications while still providing high channel density and cable count.

An electrical component is provided, comprising at least one plug-in socket for receiving an accommodated component, in particular a relay or an optocoupler, in or on the electrical component, the accommodated component having first electrical contact elements on its underside, for being electrically connected to second electrical contact elements of the electrical component, and wherein in an active position of the accommodated component, the first electrical contact elements are electrically connected with the second electrical contact elements of the electrical component on the plug-in socket, and comprising a manipulation means, by means of which the accommodated component can be more easily plugged into the active position in the plug-in socket and/or pulled out thereof, wherein the manipulation means has a spacing portion, and wherein a free end of the spacing portion protrudes beyond the electrical component and/or beyond the accommodated component that is inserted in the plug-in socket in the active position.

A slot cover and an integrated circuit access device having the slot cover are provided. The slot is used to be removably inserted into a slot of an electronic device and includes a frame, a positioning portion, an engaging portion, and at least one conductive elastic plate. The frame includes a center sheet, a first-side sheet configured to connect to an integrated circuit access module, and a second-side sheet. The first-side sheet and the second-side sheet are respectively located at a first side and a second side of the center sheet. The positioning portion and the engaging portion are respectively located above and below the center sheet. The at least one conductive elastic plate is disposed at the second-side sheet. When the slot cover is inserted in the slot of the electronic device, the center sheet blocks an opening of the slot.
