Description

  The present invention relates to a conduit connector and a component with a conduit connector for connecting a corrugated tube used as a flexible conduit made of synthetic resin mainly used for indoor and outdoor wiring construction.

  Conventionally, when embedding an electric wire in a ceiling slab, floor slab, or wall of a double ceiling, a flexible resin tube made of synthetic resin has been widely used to protect the wire from concrete. A corrugated tube is used.

  The corrugated tube has a so-called bellows shape in which concave and convex shapes are continuously formed in the tube axis direction, is lightweight, and can be bent freely during wiring construction.

  A conduit connector is used to connect the corrugated tubes. In addition, when an electric wire embedded in a ceiling slab is pulled down to the space between the ceiling slab and the ceiling finishing material, an end cover is attached to the surface layer of the ceiling slab. A conduit connector is also used for connection with the buried electric wire.

  FIG. 16 is a perspective view showing a configuration of a conventional conduit connector.

  A conduit connector 100 shown in FIG. 1 includes a cylindrical conduit connector main body 101 and a cylindrical cap 102 having a diameter larger than that of the conduit connector main body 101.

  The strips 102a are formed at equal intervals in the circumferential direction on the inner peripheral surface of the cap 102, and the troughs of the corrugated tube 103 are formed at the tips of the strips 102a as shown in FIG. A claw portion 102b that can enter the portion 103a is formed.

  The outline of the connection and disconnection method of the corrugated tube using the conduit connector 100 is as follows.

a. When connecting the corrugated tube, the engaging convex portion 102c protruding from the inner peripheral surface of the cap 102 is aligned with the introducing portion 101b of the engaging concave groove 101a of the conduit tube connector main body 101, and the cap 102 is connected to the electric wire. Attached to the pipe connector main body 101.

  When the cap 102 is rotated in the direction of arrow A, the engaging convex portion 102c is fitted into the fixing portion 101c of the engaging concave groove 101a, whereby the cap 102 is coupled to the conduit connector main body 101.

  In this state, as shown in FIG. 17A, when the corrugated tube 103 is inserted rightward toward the back side of the cap 102, the corrugated tube 103 is smoothly inserted while pushing up the claw portion 102b. In this state, when the corrugated tube 103 is pulled out in the left direction, the corrugated tube 103 is prevented from coming off by the claw portion 102b engaged with the valley portion 103a.

b. Next, when removing the corrugated tube 103, when removing the corrugated tube 103, the cap 102 is turned in the direction opposite to the direction of the arrow A, so that the engaging convex portion 102c becomes the releasing portion 101d of the engaging concave groove 101a. Move.

  Since the release portion 101d is formed obliquely toward the inner side in the tube axis direction of the conduit tube connector main body 101, the cap 102 moves to the inner side of the conduit tube connector main body 101 via the engaging convex portion 102c. To do.

  At this time, since the tip of the strip 102a rides on the inclined surface 101e of the conduit connector main body 101 and is expanded in diameter (see FIG. 17B), the corrugated tube 103 can be detached from the conduit connector 100 ( For example, see Patent Document 1).

  However, in the above-described conventional conduit connector, the operation procedure of the cap 102 when connecting or disconnecting the corrugated tube is complicated, and specifically, how much the cap 102 is rotated in which direction. There is a problem that it is difficult to know whether it is possible to connect and to be able to cancel the connection. Moreover, the direction of the force required to pull out the corrugated tube from the conduit connector is different from the direction of the force required to release the conduit connector, and the connection release operation becomes complicated.

  In particular, in a work environment where sufficient illumination cannot be obtained, there is a problem that workability is poor even if the operation method is indicated by characters or symbols on the cap 102 or the conduit connector main body 101.

  Further, there is a problem that the cap 102 is forgotten to be returned to the original connection state after the release work.

The diameter of each engaging claw is expanded so as to run on the outer peripheral surface of the inner cylinder when And summarized in that in a state in which are held in the annular groove.

  In the present invention, being slid in a relatively close direction means that the operating body is slid in the corrugated tube insertion direction relative to the conduit body, and the conduit body is moved relative to the operating body. The case of sliding in the direction opposite to the corrugated tube insertion direction is included.

  Examples of the corrugated tube include a PF tube (Plastic Flexible Con-duit) as a synthetic resin flexible electric wire tube having flame resistance, and a CD (Combined Duct) as a synthetic resin flexible electric wire tube having no flame resistance. Pipes are included, and each pipe is classified according to the flame retardant composition, with polyethylene, polypropylene, etc. as the main material.
