The invention relates to a device for holding in position and placing in electrical contact (5) for a connection terminal of an electrical apparatus (1), arranged to hold in position and place in electrical contact at least two electrical conductors (7a, 7b ), the device (5) comprising: a first retaining element (9a) having a first engagement portion (19a) arranged to engage, in a retailing position, with a first electrical conductor (7a); a second retaining element (9b) having a second engagement portion (19b) arranged to engage, in a retaining position, with a second electrical conductor (7b ); and a clamping point (23) defined at least partially in the retaining position by the first engagement portion (19a) and the second engagement portion (19b).

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).

A conductor terminal with an insulating material housing and a spring-force terminal connection. The spring-force terminal connection has a contact body which is shaped out of a sheet element and has a base portion, lateral wall portions that protrude from the base portion and are mutually spaced, and solder connection contact tongues. The base portion together with the lateral wall portions forms a conductor receiving channel for receiving an electric conductor, and leaf spring tongues protrude from the lateral wall portions so as to face one another, each leaf spring tongue has a clamping edge for clamping an electric conductor received in the conductor receiving channel. The insulating material housing has a conductor insertion opening which leads to the conductor receiving channel on the front face.

The invention relates to an electrical contact for a conductor terminal that has an insulating material housing, wherein the contact has a terminal section for connection to an electrical conductor, wherein the terminal section has a spring force clamping connection with at least one clamping spring for connection of the electrical conductor under spring force. The invention also relates to a conductor terminal having at least one such electrical contact.

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.

A connection housing includes a connection housing rear wall, at least one open area, and at least one connection device for a conductor. The connection device preferably has at least individual conductor connections. Each individual conductor connection has a metal contact element, a spring support which is made of a non-conductive material such as synthetic plastic, and includes a base wall and a clamping spring. The spring support is inserted into the open area such that the base wall lies parallel to the rear wall of the connection housing at a distance therefrom. The base wall forms a guide for conductors to be inserted, and the base wall completely or partly closes the housing towards the outside in the region of the open area.
