Description

A web interface with fool-proof features

technical field

The utility model relates to the technical field of improved design of a network interface, in particular to a network interface with foolproof function.

Background technique

The network crystal head we usually refer to refers to the RJ45 crystal head, which is a connector with 8 pins, "RJ" means the registered jack, and "45" means the serial number of the interface standard. RJ45 crystal plugs are usually terminated on Ethernet cables and are used to connect various network devices such as computers, routers, switches, etc. The crystal head of the telephone line refers to the RJ11 crystal head, which is very similar to the RJ45 crystal head, but only has 4 pins. It is a connector developed by Western Electronics Company and is often used to connect telephones and modems. The difference between the RJ45 crystal head and the RJ11 crystal head is that the structure is different. The RJ45 crystal head is a connector with 8 grooves and 8 contacts (8p8c), while the RJ11 crystal head usually only has 6 grooves and 4 contacts (6p4c). Therefore, the volume of the RJ45 crystal head is larger than that of the RJ11 crystal head. The RJ11 crystal head can usually be inserted into the RJ45 interface, and vice versa, but it is strongly recommended not to use the RJ11 crystal head for the RJ45 interface, so as not to prevent the metal terminal conductor arm in the RJ45 interface from being damaged by the RJ11 crystal head.

In the prior art, the patent application number CN201020668307.6 discloses a new and practical anti-misplug computer network interface kit, including a new type of plug and socket, which can effectively prevent wrong connection of computers between different networks. The new plug and the new socket are designed with matching guiding and limiting features, and can be inserted into each other; the new plug cannot be inserted into the RJ45 socket, and the RJ45 crystal head plug cannot be inserted into the new socket; the shape, position, size, and quantity of the limiting and guiding features of the new interface kit can be determined according to the needs, and interface kits of various specifications can be produced to meet the requirements of preventing misplugging between various networks. The new plug and socket use common network cable manufacturing and testing tools, so that the cost of network transformation is small, and the use is convenient and flexible.

In the above technical solution, it is necessary to re-determine the shape, position, size, and quantity of the limit and guide features of the new interface kit, and make interface kits of various specifications to meet the anti-mis-insertion requirements between various networks. It is relatively complicated for the anti-mis-insertion operation between the RJ45 crystal plug and the RJ11 crystal plug and the corresponding interface.

In order to solve one of the above problems, the present application provides a network interface with foolproof function.
