Description

Be used for orbital quick binding post of lamp decoration and terminal box

Technical Field

The utility model relates to the field of lamp decoration track accessories, in particular to a rapid wiring terminal and a wiring box for a lamp decoration track.

Background

In the existing track lamp technology, a lamp decoration track structure formed by a series of track segments is generally adopted. Each track section is provided with a conducting strip, and one end of each track section is spliced with the junction box, so that the electricity taking function of the lamp is realized. The conductive strips are typically made of a metallic material and are mounted inside the track segments. In order to realize the contact conduction between the junction box and the conducting strip, a wiring terminal is arranged in the junction box. One end of the wiring terminal is electrically connected with an external power transmission wire, and the other end of the wiring terminal is in contact conductive connection with the conductive strip.

However, in the prior art, most terminals use screws to compress the external power wires to ensure a stable power connection. There are some problems with this approach. First, the pressure of the screw is not uniform or stable, which may cause an unstable electrical connection between the end of the external power transmission line and the connection terminal, thereby causing a problem of poor contact. This may result in an inability of the current to flow smoothly through the terminal and the strip, causing localized heating, arcing or spark generation, increasing the safety hazard of an electrical fire. Secondly, the end extrusion area of the screw is smaller, and virtual connection possibly occurs in the process of installing the external power transmission wire or only partial wire bundles connected with the external power transmission wire can be pressed tightly. In this case, current cannot flow through the wires and terminals as intended, and the risk of fire is increased as well.

Moreover, a broken connection or a failure to fully compress the wire may also increase the risk of electrical shock when people contact the wire and terminal. Accordingly, there is a need for further optimization and improvement of existing terminal blocks and terminals within terminal blocks.
