WIRE CONNECTION TERMINAL APPARATUS
Field of the Invention
The present invention relates to a wire connection terminal apparatus, and in particular to a wire connection terminal apparatus comprising a quick release/attachment mechanism, and to a method of producing the same
Background
Electrical wire connection terminals are known in various forms, for example as box terminals, circuit board terminals, terminal blocks or as conductor connection terminals in other electrical devices.
Conventional wire connection terminals can however be located in restricted spaces and can be difficult to access and to connect each wire to the desired location. Furthermore, the wires may need to be connected to respective connectors using screws, which require the user to use a screwdriver to release and to secure the wire from the connector. The operation of releasing and/or securing a wire with the respective connector within the wire connection terminal may therefore be time consuming.
There is therefore a need for a wire connection terminal apparatus which is easy to access and to release/secure wires to the corresponding connector within the 25 apparatus without the need for additional tools to be used. There is a need for a quick release wire connection terminal apparatus.
Prior Art
GB2552971 discloses an electrical connection apparatus comprising a chassis, and one or more electrical connection devices carried thereon, wherein the, or each, electrical connection device comprises a lever-operated mechanism by which a wired electrical connection may be made thereto, and the, or each, electrical connection device is carried on the chassis in a substantially fixed manner relative thereto. The electrical connection device may comprise a lever-operated wire-retention or wiretapping mechanism.
EP3018760 discloses a wire connection terminal structure including a seat body and a conductive clip disposed therein. One end of the seat body has an extending side and a recessed side, and a slope formed between the extending side and the recessed 5 side. The conductive clip has a holding mouth. The slope is formed with a wire plug-in opening aligned with the holding mouth. A wire plug-in protection wall is formed on an edge of the recessed side. The wire plug-in protection wall protrudes in a direction as an extending direction of the extending side. The slope and the wire plug-in protection wall define a recessed configuration on the end of the seat body. The wire plug-in 10 protection wall on the outer edge of the wire plug-in opening provides a shielding effect so that the conductive wire or contact pin can be easily aimed at and plugged into the wire plug-in opening.
EP2956992 discloses a conductor terminal described having an insulating material housing and having at least one spring-loaded clamping connection in said insulating material housing and having at least one actuation element that is pivotably accommodated in the insulating material housing and is designed to open in each case at least one associated spring-loaded clamping connection.
The present invention arose in order to overcome problems suffered by existing devices.
