An electric apparatus comprises a casing formed of an electrically insulating material and at least one connection terminal mounted in the casing and intended to establish and maintain a contact between an electrical conductor inserted in the connection terminal and an electrical link bar mounted in the casing to ensure an electrical connection between the electrical link bar and the electrical conductor. The connection terminal is of the push-in type and comprises a contact spring configured so that the contact between the electrical conductor and the electrical link bar results from a force insertion of the electrical conductor in opposition to the action of the contact spring and is automatically maintained by the contact spring after insertion of the electrical conductor. The casing comprises a peripheral wall and a cover configured to be assembled together along a mounting direction substantially parallel to the direction in which the electrical conductor is inserted in the connection terminal.

An external electrical wire can be plugged into the holding mouth and held between the holding section and the base section and electrically connected with the conductive plate. The conductive plate and the fixing frame are two separate components so that the conductive plate is solely made of a high-conductivity material, while the fixing frame is made of a material with higher structural rigidity.

A signal lead adapter according to the present invention comprises at least a clamper which is formed at one end of a base plate and two clamping plates integrally formed with and upwardly extending from the base plate. Each clamping plate comprises a first clamping section with a predetermined length and a first clamping surface forming into a first holding ditch with a first radius. Each clamping plate also comprises a second clamping section with a predetermined length and a second clamping surface forming a second holding ditch with a second radius. The signal lead of different radius can be inserted and hold in either the first holding ditch or the second holding ditch. The signal lead can be inserted into the adapter and pulled out from the same easily without causing damage of the flexibility as well as the metal coating layer of the clamping plates.

A contact element for connecting an electrical conductor and a conductor terminal with such a contact element are provided. The contact element includes a conductor insertion area in which there are two opposite first side walls, a first floor section connecting the first side walls and a first cover section opposite the first floor section. The first side walls, the first floor section and the first cover section limit a conductor insertion channel. One or both first side walls each have at least one spring tongue freed from the first floor section and the first cover section, which tongue forms a clamping point for clamping an electrical conductor by means of a spring force.

The invention relates to a plug connector contact carrier (1) for selectively populating with electrical crimp contact elements (10) or electrical screw contact elements (20), comprising a plurality of contact chambers (2) for the contact elements, which contact chambers are provided in a contact grid, wherein the contact carrier has insertion openings (11) for inserting the contact elements into the contact chambers and wherein furthermore the contact chambers are property designed in such a way that selectively either a crimp contact element or a screw contact element can be inserted into and mounted in the contact chamber.

A spring-loaded terminal contact (3) for contacting electrical conductors having at least one busbar (7) and having at least one clamping spring (9) which has an abutment member (10), a clamping member (12) and a curved resilient member (11) which is arranged between the abutment member (10) and the clamping member (12) is described. The clamping member (12) extends in the direction toward the busbar (7) and has a resilient clamping edge (8) for clamping an electrical conductor which is introduced between the clamping member (12) and the busbar (7) in a conductor insertion direction (L). The busbar (7) has a clamping edge (6) which together with the resilient clamping edge (8) forms a clamping location for the electrical conductor which is intended to be clamped. The busbar (7) has a groove-like recess (14) in the conductor insertion direction (L) upstream of the clamping location adjacent to the clamping edge (6).

Configurations for push wire connectors and for electrical wiring devices that mate with or connect to the push wire connectors are disclosed. The push wire connectors have a housing and one or more contact assembly positioned within the housing. Each contact assembly has one or more contact openings to allow wires to pass through, and the housing has one or more wire entry openings that are angled so that wires that pass through the wire openings and the contact openings before engaging the contact assembly are angled.

A terminal block includes an insulating casing defining a recess receiving a conductive bar and a retaining spring. The conductive bar includes a base portion, a support leg attached to the base portion and a cooperating leg attached to the base portion. In a mounted position of the conductive bar and the retaining spring within the recess, the support leg engages with a support part of the retaining spring, and the cooperating leg is positioned to engage with a conductor inserted into a plug of the terminal block.

A cable connector for decreasing signal return loss includes a front cap, a base, and a connecting terminal. A first hole is formed on the front cap, and a second hole is formed on the base. A second front side of the base connects to a first back side of the front cap. The connecting terminal includes an elastic clamping part, a wire connection part, and a lead part. A back side of the clamping part is a free end, and a front side of the clamping part is connected to the wire connection part. The lead part is mounted in front of the wire connection part. The connecting terminal is mounted in the base, and the lead part pierces the front cap covering the connecting terminal through the first hole.
