Abstract

The invention discloses an electric heating fusion connecting piece for connecting smooth wall plastic pipes. The electric heating fusion connecting piece comprises a plastic pipe, and electric heating wires for connecting are uniformly distributed in the plastic pipe; a notch is formed in one side of the plastic pipe in the axial direction, an electric heating wire for sealing is arranged in theportion, at one side of the notch, of the plastic pipe, and sealing convex nails are arranged on the other side of the plastic pipe; and the electric heating wire for connecting and the electric heating wire for sealing are both connected to a wiring head. The connecting piece has the advantages of being easy to sleeve, free of gaps and simple in construction.

Description

technical field [0001] The invention relates to a connecting piece for connecting plastic pipes, in particular to an electric hot-melt connecting piece for connecting smooth-walled plastic pipes. Background technique [0002] The electrofusion connector is one of the most commonly used connectors for plastic pipe connections at present. Its main principle is to pre-embed the heating wire inside the connector. After the connector is connected to the plastic pipe, the heating wire is heated to make the connector and The contact surface of the plastic pipe melts to make them blend together, and the connection can be completed after cooling. The connection is highly sealed and strong. [0003] However, there are currently two types of hot-melt connectors. One is a full-circle connector whose inner diameter is consistent with the outer diameter of the plastic pipe. On the pipe, at the same time, due to the fixed size, a small gap will be formed after the contact surface is melte...
