A system has an electronics housing and a grounding contact assembly for electromechanical switchgear that can be mounted on a mounting rail, wherein the grounding contact assembly can be mounted in the electronics housing. The base region of the electronics housing faces a mounting rail, is provided with an externally accessible mounting duct for a grounding contact that can be mounted in the duct, and contacts the mounting rail in a spring-leaded manner. The contact part has a blade contact at one end and at the other end a terminal receiving part which is angled perpendicularly to the first free end of the blade contact and is designed as a detent pin. The grounding contact assembly can be pushed into the mounting duct irrespective of the position of the electronics housing on the mounting rail.

Provided is a plug connector module for inserting in a holding frame of a modular plug connector. The plug connector module is provided so as to make electrical contact with the holding frame. A housing that forms the plug connector module is embodied from metal and can be connected in a mechanical and electrically conductive manner by way of a first type of fastener and a second type of fastening means to the holding frame.

A terminal block assembly is provided, comprising a plurality of terminal blocks mounted on a common horizontal support member, including a supply terminal block connected with a voltage source, and a plurality of distribution terminal blocks connected with a plurality of loads, respectively, characterized in that the length and height dimensions of the terminal blocks are the same, but the width of the supply terminal block is greater than that of the distribution terminal blocks, and that the supply conductor contact arrangements of the supply terminal block are designed for connection with a supply conductor having a relatively large cross-sectional area, while the distribution conductor contact arrangements of the distribution terminal blocks are designed for connection with distribution conductors having a relatively small cross-sectional area. A conductive comb member extends transversely across the assembly to interconnect the electrical circuitry contained within the terminal block housings.

A neutral bus bar for an electrical distribution apparatus. The neutral bus bar includes an elongated body that has a rail and a plurality of wire connectors arranged. Each of the wire connectors includes a side hole on the body and a top hole. The side hole can receive an electrical neutral wire such as from a pig tail type circuit breaker. The top hole has a mouth which opens onto the recessed channel and can receive a tightening screw to secure the received electrical wire in the side hole.

An earth-conducting element includes a conductor lamina designed to electrically connect together two wires and a substantially vertical shaped body extending in the longitudinal direction. The substantially vertical shaped body including a bottom body section having a bottom free edge, a first end, a second end, and a flat-lamina spring. The bottom free edge extends in the longitudinal direction for resting in the vertical direction on a DIN-standard rail. The first end includes a tooth to engage with one of the two folded flanges of the DIN standard rail B. The second end is opposite to the first end and is designed to form a means for engaging and retaining the flat-lamina spring. The flat-lamina spring includes a head and two flat-pins legs for engagement with the other folded flange of the rail.

An electronic device is detachably mounted on a DIN rail. The DIN rail includes a first protruding edge and a second protruding edge. The electronic device includes a main body and two clips. The two clips are movably disposed on the main body. Each clip includes a base and an extension part. The base includes a notch. The notch is selectively engaged with or disengaged from the first protruding edge or the second protruding edge. The extension part is connected with the base and extended from the base. The extension part includes a double-bevel bulge and an elastic extension arm. The elastic extension arm is located beside the double-bevel bulge. A free end of the elastic extension arm has an engaging part. The notches of the two clips are engaged with or disengaged from the first protruding edge and the second protruding edge, respectively.

A conductive component structure of rail-type terminal device includes a conductive component disposed in an insulation case body. The conductive component has a first section and a second section connected with the base section. The first section and the second section are respectively formed with a bow portion, a first portion and a second portion. A load arm and an elastic unit assembled with the load arm are disposed on the first section and/or the second section. The elastic unit includes a first elastic section and a second elastic section. The load arm passes through the first elastic section and at least a part of the second elastic section. When the load arm is displaced or moved, the first elastic section and the second elastic section respectively provide tension (or pushback force) and pulling force effect so as to improve the shortcoming of the conventional terminal device.

A rail holding structure of rail terminal includes a case body and a grounding member received in the case body. Two lateral sides of the grounding member are connected in the case body for holding a preset grounding rail. The case body is formed with two lower sections respectively corresponding to two sides of the grounding member. A foot section extends from at least one of the two lower sections. A first connection side and a second connection side are disposed on two lateral sides of the foot section. The first and second connection sides are connected with an outer sidewall of the lower section to form a socket with an open top side. A tool can be extended into the socket to pull and extend the foot section. Via the lower section, the grounding member is driven to detach from the grounding rail or hold the grounding rail.

A busbar unit for a hybrid vehicle includes an integrally formed housing part. The busbar unit also includes contact terminal parts which are installed at an inner side of the housing part. The busbar unit further includes a connector part which is coupled to a front surface of the housing part to be electrically connected to the contact terminal parts. The busbar unit yet further includes a coupling member which is coupled to the connector part via the contact terminal parts at a lower side of the housing part. The busbar unit includes a grounding bracket including one end fixed to a front surface of the connector part and the other end extending toward a seating surface for electrical grounding to the seating surface of a motor cover where a bottom surface of the housing part is seated.
