The present disclosure relates to an electrical contact assembly of a plug-in connection terminal, which has an electrical contact having a first connector element for connecting a plug-in contact in a plug-in direction, a second connector element for connecting an electrical conductor in a clamping manner being arranged on the electrical contact, the first connector element having at least one contact element that has at least one first section and one second section, the width of the first section at a right angle to the plug-in direction being greater than the width of the second section at a right angle to the plug-in direction.

An electrical connector comprises a contact, an electric wire connection spring connecting an electric wire to the contact, and a housing. The housing includes a contact accommodating portion receiving the contact, a mechanism accommodating portion receiving the electric wire connection spring, and a lock arm supported on the contact accommodating portion in front of the mechanism accommodating portion and configured to catch a mating connector. The mechanism accommodating portion has a front opening disposed between a rear end portion of the lock arm and the electric wire connection spring.

An electrical connector comprises a contact, a housing retaining the contact, and a lock arm configured to catch a mating connector. The lock arm has an arm main body integrally formed with the housing and a releasing operation portion formed separately from the housing and attached to the arm main body.

The terminal block includes a movable operation feeling generating member (60) which generates an operation feeling according insertion of a conductor portion into an accommodating portion (12) from a first opening portion (111), and a first protruding portion (63) disposed in the accommodating portion to be capable of coming into contact with the movable operation feeling generating member being rotated by the insertion of the conductor portion into the accommodating portion from the first opening portion after the conductor portion and a terminal electrode portion (20) are changed from the non-connected state to the connected state. The movable operation feeling generating member includes a first contact portion (61) capable of coming into contact with the conductor portion inserted into the accommodating portion, and a second contact portion (62) which has a second protruding portion (70) generating the operation feeling by coming into contact with the first protruding portion (63).

Electrical wiring devices that incorporate clamp-type wire terminal connections are described. The electrical wiring devices include for example, single and duplex blade-type electrical receptacles, blade-type locking electrical receptacles, single or multi-pole electrical switches, combination switches and blade-type receptacles, blade-type plugs for electrical cords and blade-type connectors for electrical cords. The electrical wiring devices include a plurality of contact assemblies. Each contact assembly includes a wire terminal and a plunger.

A terminal block includes a state display portion which displays whether a conductor portion and a terminal electrode portion are in a connected state or a non-connected state at a third opening portion and a movable display member. The movable display member has a main body portion capable of reciprocating in a direction intersecting a terminal connection surface, a contact portion capable of coming into contact with a conductor portion inserted from a first opening portion into an accommodating portion, a force transmitting portion which moves the main body portion toward the terminal connection surface when the conductor portion is inserted from the first opening portion to the accommodating portion, and rotating mechanism portions which rotate the state display portion so that display of the state display portion can be changed between a connected state and a non-connected state in accordance with the reciprocating movement of the main body portion.
