A conductor assembly structure for a rail-type terminal device includes a conductor assembly and an insulating housing. The conductor assembly structure can reduce manufacturing waste and has a larger contact surface and a better electric conduction effect. The conductor assembly has a base portion that can be pivotally connected with a conductive connector, and a first area and a second area connected to the base portion. The first area and the second area are respectively formed with a bowed portion and a first section and a second section connected to the bowed portion to be snapped onto a grounding mounting rail. At least one of the first area and the second area is provided with a load arm and an elastic member connected to the load arm for increasing the elastic fixing effect (force) of the first section and/or the second section on the grounding mounting rail.

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 connecting apparatus for connecting a current-carrying element to a rail element includes: a receiving body on which the current-conducting element is fastenable, the receiving body having a first transverse side and a second transverse side opposite the first transverse side, and a first longitudinal side and a second longitudinal side opposite the first longitudinal side; a first latching arm for fastening the connecting apparatus to the rail element; and a second latching arm for fastening the connecting apparatus to the rail element. The first latching arm is joined to the first transverse side of the receiving body. The second latching arm is joined to the second transverse side of the receiving body.

A shield device includes: a first electrical conductor; an electrical insulator that is configured to electrically insulate the first electrical conductor from a second electrical conductor; a first shield connector configured to: directly contact at least 180 degrees of a first circumference of a first shield that surrounds at least two first insulated conductors of a first section of a shielded cable; and electrically connect the first shield with the first electrical conductor; and a second shield connector configured to: directly contact at least 180 degrees of a second circumference of a second shield that surrounds at least two second insulated conductors of a second section of the shielded cable; and electrically connect the second shield with the first electrical conductor.

A metal protective conductor connection element has a metal foot arrangement which has at least one first metal foot and at least one second metal foot for supporting on a support rail. The first metal foot has a first spring element with a contact region for forming a force-fitting connection of the first spring element of the first metal foot to the support rail and a second spring element with a securing region for forming a form-fitting connection of the second spring element of the first metal foot to the support rail. The second metal foot has a first spring element with a securing region for forming a form-fitting connection of the first spring element of the second metal foot to the support rail and a second spring element for forming a form-fitting connection of the second spring element of the second metal foot to the support rail.

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.

Modular switchboard terminal block (10,20) for transmission of data signals (2) is provided, comprising a container (10a,20a) having, arranged inside it, a printed circuit (30) for processing the data signals, which has two opposite sides (30a,30b) in a transverse direction (Y-Y); connectors (11;21) for electrical connection to controlled/detection devices; and a rear end face provided with hook and spring means for mounting on a DIN switchboard rail (6).

A circuit breaker that may be plugged onto an electrical panel. The circuit breaker is preferably a low voltage circuit breaker in the range of 120-240 volts. The circuit breaker includes an electrical clip with a curved inner surface that contacts a curved outer surface of an electrical connector on the electrical panel. The circuit breaker includes a protrusion that prevents the circuit breaker from being installed in electrical panels without an electrical connector for the electrical clip to engage.

A contact assembly for an electrical connector includes a contact positioner having contact support walls holding a contact array. The contact array includes signal contacts and ground contacts interspersed with the signal contacts. The signal contacts include mating ends configured to be mated with a mating electrical connector and mounting ends configured to be terminated to a host circuit board. The signal contacts include transition portions between the mating ends and the mounting ends. The ground contacts include mating ends, mounting ends, and transition portions between the mating ends and the mounting ends. The contract assembly includes a ground bus wire extending transversely across the contact array. The ground bus wire is electrically connected to each of the ground contacts. The ground bus wire is electrically isolated from each of the signal contacts.
