PIPE JOINT FOR SQUARE ELECTRIC WIRE TUBE, AND CONNECTION STRUCTURE OF SQUARE ELECTRIC WIRE TUBE AND PIPE JOINT FOR SQUARE ELECTRIC WIRE TUBE

摘要

To provide a pipe joint for a square electric wire tube, and a connection structure of the square electric wire tube and the pipe joint for the square electric wire tube capable of connecting a small diameter part of the square electric wire tube with a female engagement part with simple structure without the need for a bolt and a nut, with a one-touch operation.SOLUTION: A pipe joint 1 for a square electric wire tube is primarily composed of a joint body 3 and a Π type fixing member 5. The Π type fixing member 5 is composed of a top surface part 7 and one pair of foot parts 9. A fixing portion 2 of a small diameter part is formed at one side of the joint body 3. The fixing portion 2 of a small diameter part is a part for fixing a small diameter part of the square electric wire tube explained below. A male joint 4 is formed at the other side of the joint body 3. The male joint 4 functions as a fixing portion of a female fitting part of the square electric wire tube explained below. A connection wall 34 perpendicular to the pipe axis direction of the joint body 3 is formed between the fixing portion 2 of a small diameter part and the male joint 4 of the joint body 3. That is, the fixing portion 2 of a small diameter part is connected to the male joint 4 by means of the connection wall 34.SELECTED DRAWING: Figure 1
