Description

Technical Field

[0001] The utility model relates to the technical field of connection, in particular to a quick-connect plug of a DC lamp tube. Background Art

[0002] When low-voltage 24V DC lamps are connected in series, the current is relatively large. In the prior art, when DC lamps are installed in series, the cables on the lamps are usually connected through plugs and sockets (male and female plugs). However, the male pins of the male and female plugs with anti-drop designs on the market are mostly round holes, and the contact area between the copper sheets is small. Therefore, their rated current is generally only 8-10A, which directly limits the number of DC lamps that can be connected in series. If you want to increase the number of series connections, you can only reduce the power of the lamp and reduce the working current. The brightness of the DC lamp can only be reduced accordingly, which cannot meet people's requirements for brightness. Therefore, it is necessary to invent a quick-connect plug with anti-drop\quick connection and a rated current of 25A-32A, and a cable with a corresponding wire diameter to ensure brightness while being able to connect more DC lamps in series.

[0003] In order to solve the problems in the background technology, the utility model provides a quick-connect plug for a DC lamp tube, and adds a redundant design to achieve compatibility with a variety of lamp tube fixings. At the same time, it solves the problem that the cable can easily be detached from the plug and socket due to many factors such as collision, vibration, and pulling of the cable during the use of the DC lamp tube, resulting in poor connection or disconnection.

[0004] This plug adopts multiple anti-drop designs, and with the help of automation, it can easily achieve error-free finished product assembly and rapid mass production. Summary of the invention
