Description

[Technical field]

[0001] The utility model relates to a novel joint. [Background Technology]

[0002] In the existing connectors, the male connector and the female connector are generally connected by interference fit. Therefore, after multiple plugging and unplugging, the male connector and the female connector are easy to loosen, resulting in poor contact. At the same time, it takes certain skills to press the buckle to separate the male connector and the female connector. In addition, the product is not foolproof, and it is easy to reverse the plug and cause a short circuit. In order to ensure that users use it correctly and conveniently, training is required, which not only generates certain educational costs but also hinders the application and promotion of the product. On the other hand, there is a gap between the male connector and the female connector after they are plugged in, and water vapor can easily enter through the gap and accumulate into water droplets, causing a short circuit. During production, the connector and the plastic shell combination of the pin and the wire can only be inserted one by one manually, and automated production cannot be achieved.
