Abstract

PURPOSE:To prevent that an adhesive is squeezed out in a pipe and the fluid in the pipe is contaminated with the solvent of the adhesive by combining connection by using an adhesive with welding-connection by means of an electric heating coil. CONSTITUTION:A cylindrical surface 22 of a smaller diameter is formed on the apex of a spigot 21. An electric heating coil is wound around the cylindrical surface and the backward outer surface is coated with an adhesive 3. The spigot is thereafter pushed in a faucet 11 and the apex of the spigot is pressed against the step part of a stopper 12 formed at the inner part of the faucet 11. An electric current is sent to the electric heating coil drawn outside to heat both the inner surface of the faucet 11 and the apex surface of the spigot 21, which are thereby melted to fuse each other. As the connection with the adhesive is done only on the opening side of the faucet, the adhesive 3 is not squeezed out into a pipe from the inner part of the faucet 11 and the apex of the spigot 21 when the connecting operation is carried out. There is no possibility that the solvent of the adhesive is ooze out as the inner part of the faucet and the apex of the spigot are fused with each other.

するという問題があった。However, in the case of this adhesive connection, after applying the adhesive to the inner peripheral surface of the socket and the outer peripheral surface of the socket, when connecting by pushing the difference [] into socket [1], the inner circumference of the socket The adhesive applied to the surface may be scraped off and moved to the back of the socket, and the adhesive may leak into the pipe from between the back of the socket and the tip of the socket, and the solvent may ooze from this adhesive. There was a problem that the water was discharged and contaminated the washing water.

。(Means for Solving the Problems) The present invention provides for the connection between the inner peripheral surface of the opening side of the socket 11 and the outer peripheral surface of the socket 21 when inserting the socket 21 into the socket 11 and covering the connection. Adhesive bonding is performed with an adhesive 3 interposed between them. On the other hand, the inner circumferential surface of the deep part of the socket 11 and the outer circumferential surface of the tip of the spout 21, or the gap protruding from the deep part of the socket 11, the one-step part 12 and the spout 1.
A heating wire 3 is interposed between the end surface of the socket 11 and the end surface of the socket 1, and by energizing the heating wire 3 to reduce heat generation, the inner part of the socket 11 and the fourth socket 2 are connected.
1 and the leading end portion are welded and joined, thereby completely blocking contact between the adhesive 3 and the fluid in the pipe.

以下、本発明の具体的構成を実施例に阜づさ訂細に説明

It is formed to be slightly smaller than the outer diameter of. Further, a stopper stepped portion 12 having an inner diameter approximately equal to the inner diameter of the Plus Deck tube 2 is provided at the back of the socket 1'1. On the other hand, a round cylindrical surface 22 with a step and a small outer diameter is provided at the tip of the spout 21, and a heating wire 4 such as a nichrome wire is wound spirally around this cylindrical surface 22. There is.

First, a small-diameter cylindrical surface 22 is formed at the tip of the spigot 2-1, the heating wire 4 is wound around this cylindrical surface 22, and after IC is applied, the adhesive 3 is sprinkled on the outer periphery of this rear position to receive the cylindrical surface 22. Push it into the opening 11 and press the tip of the spigot 21 against the stopper step 12 provided at the back of the socket 11. Therefore, the heating wire 4 pulled out to the outside is energized to generate heat, and the inner peripheral surface of the inner part of the socket 11 and the spigot 21 are connected to each other.
At the same time, the tips of the two are melted and welded together.
