They need to be connected to other computers and other devices through network cable connectors to achieve more functions and requirements. And because the network cable connector is generally arranged at the bottom of the printer, there is a phenomenon of short circuit caused by water ingress, which brings troubles to users and greatly affects the satisfaction of users with the product.

The Chinese patent application number is 201520236970.1, which provides a waterproof network connector plug, including a plug body, an end cover and a network connector. The aforementioned plug body is hollow in the axial direction. The plug also includes a card seat and a sealing cylinder. The aforementioned card seat has a hollow axial cavity. The arrangement of clamping claws constitutes that the sealing cylinder is hermetically built into the axial cavity of the card holder, and the data line of the network connector passes through the axial cavity. Although this kind of network joint improves the waterproof performance of the joint by setting the sealing cylinder and the network cable sealing setting, the overall connector has the following problems: 1. The sealing between the increased plug body, end cover, card seat and snap ring is really difficult to guarantee , and the waterproof structure is relatively complicated, and the waterproof structure of the plug part requires four or five parts; 2. There are devices that need to set the corresponding network cable interface to a structure that matches the plug body, which limits the design of the device; 3. After the waterproof structure is installed, it is difficult to pull out the plug, and it is impossible to manually touch the shrapnel of the plug to remove the plug; 4. The waterproof performance of the port position of the network cable has not been solved.
