Technical Field

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

Background

In the existing track lamp technology, a lamp rail is a lamp decoration track, the structure of the lamp rail is generally composed of a series of track sections, and the length of each track section can be adjusted according to requirements. And each track section is provided with a conducting strip so as to realize the electricity taking function of the lamp. The conductive strips are typically made of a metallic material and are mounted inside the track segments. In order to realize the contact electricity taking of the lamp and the conducting strip, a wiring terminal is arranged in a power box of the track lamp. One end of the wiring terminal is electrically connected with an external power transmission wire, and the other end of the wiring terminal is electrically connected with the conducting strip. In the prior art, the connection terminals compress the conductive strips by screws to ensure stable electrical connection. The position of the conducting strip can be adjusted by rotating the screw so as to adapt to track lamps with different length specifications. However, there are some problems with using screws to compress the conductive strips. First, the screw adjustment and tightening process is relatively cumbersome, requiring specialized tools and techniques. This results in inconvenience of assembly and waste of time. Particularly when the conductive strips of different length specifications need to be replaced, the screws need to be adjusted repeatedly, which increases the complexity and time consumption of the work. Secondly, the way in which the conductive strip is screwed may also lead to poor contact problems. The pressure of the screw is uneven or unstable, which may result in weak electrical connection between the conductive strip and the connection terminal. This may lead to a poor or interrupted current transmission, affecting the proper operation of the track light fixture. In addition, the use of screws to fix the conductive strips may also negatively impact the production efficiency of the power supply box. Because of the need for manual adjustment of the screws, each power box in the production process needs to be operated separately, increasing production time and cost.

In summary, although the conductive strips are pressed by the screws in the prior art to realize the electrical connection of the lamp, the assembly is inconvenient, the contact is poor, and the production efficiency is low. Therefore, the existing lamp decoration tracks and wiring terminals need further optimization and improvement.
