Network wire connecting device

The utility model discloses a network wire connecting device which comprises a network wire connecting device shell. At least eight network wire connecting clamp groups are arranged in the shell. Each network wire connecting clamp group comprises a network wire clamp and a groove bottom support which is arranged on a lower end of the network wire clamp and matches with the network wire clamp. An upper end of the network wire clamp is arranged outside the shell. The lower end of the network wire clamp is provided with an inverted-mountain-shaped groove. The groove bottom support is a protuberance which is arranged on a groove bottom and corresponds to a groove. The device has the following advantages that the two network wires are directly connected through a pressing clamp; cost is low, the service life is long and connection is stable; problems that wiring is not firm and a crystal head is easy to be oxidized when the crystal head is used are avoided; reliable connection of the network wires is guaranteed.
