Description

  The present invention relates to a tubular protective tube connector provided with a connecting portion for connecting a corrugated protective tube in which wiring and piping materials are disposed at both ends.

  The corrugated protective tube that protects the wiring and piping material in the double ceiling or wall is flexible, so it can be stored in a wound state and can be bent flexibly along the piping route. The protective pipe piped along the pipe path was fixed to the wall surface with a saddle or the like at predetermined intervals.

  On the other hand, it is necessary to connect this corrugated protective tube as necessary, and for this purpose, a protective tube connector for connecting protective tubes to each other has been proposed.

  FIGS. 6A to 6D are diagrams illustrating a protective tube connector that is a background art of the present invention, among such fixtures and protective tube connectors.

  The protective tube connector 20 shown in FIG. 6A is described in Patent Document 1, and is a cylindrical one provided with a receiving port 11 into which a corrugated protective tube is inserted, and is inserted into the receiving port 11. A locking portion 13a that locks the protective tube in a retaining state by movement in the radial direction (inside and outside of the receiving port 11) to the outer periphery of the protective tube, and a release operation that enables the locking to be released The latching operation part 13 which consists of the part 13b is provided.

  With such a configuration, the protective tube connector 20 can be prevented from being detached by simply inserting the corrugated protective tube into the receiving port 11. On the other hand, when the protective tube is desired to be extracted, the release operation unit 13 b is operated. Can be easily extracted.

  However, in order to fix the protective tube connected by the protective tube connector 20 to a wall or the like, it is necessary to separately fix it with a fixture called a saddle or the like.

  The protective tube connector 30 of FIG. 6 (b) is described in Patent Document 2, and has a cylindrical shape, and projects a large number of gradient protrusions 21a each having a circumferential gradient surface on one side, and the other side. A joint body 21 provided with a connection male screw, a locking operation ring 22 provided rotatably on the gradient protrusion 21a side of the joint body 21 and provided with a locking portion 22a corresponding to the gradient protrusion 21a, a joint A connection ring 23 is provided that engages with a connection male screw of the main body 21.

  With such a configuration, the protective tube connector 30 can be prevented from being detached by simply inserting the corrugated protective tube into the locking operation ring 22 side. By rotating the ring 22 in the circumferential direction, the locking portion 22a is restricted by the circumferential gradient surface of the gradient projection 21a and spreads outward, so that the protective tube can be easily extracted.

  However, in the case of the protective tube connector 30 as well, in order to fix the connected protective tube to a wall or the like, it is necessary to separately fix the protective tube with a fixture called a saddle or the like.

  FIGS. 6C and 6D show a protective tube connector having a fixing function described in Patent Document 3, and FIG. 6C shows a state before the protective tube is connected by the protective tube connector. The side view to show, (d) is the external appearance perspective view which shows the state after a connection.

  The protective tube connector 40 has a saddle-like shape generally used for fixing a pipe, and the width of the saddle and the direction in which the pipe to be fixed extends are more than twice as wide as a normal one. It is made of a flexible material and is in contact with the main body 31 that contacts the peripheral edge of the pipe, and the wall surface side of the main body 31, and the fixing for fixing the connecting device 40 to the wall surface. Part 34.

  With such a configuration, as shown in FIG. 6 (c), the protective tube connector 40 has a smooth protective tube (the outer periphery is not wavy but smooth) with an opening on the fixed portion 34 side and placed on the wall surface W. In this case, the protective tube connector 40 is wrapped from the direction orthogonal to the axial direction thereof, and then the protective tube connector 40 is fixed to the wall surface by the fixing portion 34 as shown in FIG. It can be done.

  At this time, since the main body 31 is wide, the protective tube P to be connected to the main body 31 can be accommodated in a butted state. That is, according to the protective tube connector 40, the protective tube P can be connected and fixed to the wall surface W at the same time.

  In addition, the protective tube connector 40 is assumed to fix the inflexible smooth protective tube P, and is not particularly provided with a movement restricting means in the axial direction of the protective tube P, but instead of the protective tube P. It seems that the other end is fixed in the same manner, cannot move in the axial direction, and cannot be bent, so that the protective tube P can be fixed so as not to come off.

However, in the case of a corrugated protective tube that can be bent, the fixing method using the protective tube connector 40 cannot prevent extraction. Moreover, in this protective tube connector 40, since it fixes and connects simultaneously, it cannot connect in the state which fixed the connector 40 to the wall surface etc.

  Hereinafter, embodiments (examples) of the present invention will be described with reference to the drawings.

  FIG. 1 shows an example of a protective tube connector according to the present invention. (A) is a plan view thereof, (b) is a front view thereof, (c) is a side view thereof, and (d) is a side view thereof. AA sectional drawing, (e) is an enlarged detail drawing of the elastic locking operation part of (d).

  This protective tube connector 5 has a cylindrical shape provided at both ends with connecting portions 2 for connecting a corrugated protective tube in which wiring and piping materials are disposed. A receiving port 1 is provided for receiving the protective tube to be connected by movement in the axial direction (direction indicated by a double-headed arrow in FIG. 1 (d)) with one side portion in contact with the wall surface.

  Further, the protective tube connector 5 is provided at a position other than the abutting side to the wall surface W of the connecting portion 2 (indicated by a two-dot chain line in FIG. 1B and FIG. 1C). A locking operation that locks the protective tube inserted in the receiving port 1 in a radial direction (inside / outside direction) so that the protective tube is prevented from coming off and can be released. Part 3 is provided.

  In such a basic configuration, the protective tube connector 5 is configured such that the contact surface 4a extending from the contact side of the connection portion 2 to the wall surface W toward the wall surface W and the corresponding contact surface 4a are applied to the wall surface W. A fixing portion 4 having a fixing hole 4b for fixing the protective tube connector 5 to the wall surface with a nail, a screw B, or the like in a state of being in contact is provided. This will be described in more detail below.

  The inner diameter of the receiving port 1 corresponds to the outer diameter of the corrugated protective tube, and the protective tube can be received and connected as it is. In this example, there is only one receptacle 1, but as illustrated in FIG. 3, two may be arranged in parallel, or three or more may be arranged in parallel.

  As shown in FIG. 1 (e), the locking portion 3 a of the elastic locking operation portion 3 is provided with a corrugated protective tube at the tip of a beam portion 3 c formed in a cantilever state on a part of the peripheral wall of the receiving port 1. A protrusion 3d is provided so as to enter the trough on the outer periphery of the.

  The projection 3d is inserted into the protective tube insertion side in contact with a crest on the outer periphery of the waved protective tube to be inserted to bend the beam portion 3c within the elastic deformation range, and the projection 3d is received in the receiving port 1. The insertion guide 3e is moved outward.

  Even if the opposite side of the protrusion 3d to the protective tube insertion side is pressed in contact with the crest of the outer periphery of the corrugated protective tube to be extracted, no force is generated to bend the beam portion 3c. Thus, the extraction preventing portion 3f is maintained so as to maintain the state of the protrusion 3d entering the valley.

  On the inner side of the base end side of the beam portion 3c, a bending recess 3g that makes the beam portion 3c more flexible is provided. The bending recess 3g is easy to bend in both cases where the beam portion 3c is bent to the inside of the receiving port 1 and to the outside. However, when the beam 3c is bent to the outside, it is easy to bend. The function to perform is demonstrated more greatly.

  The release operation portion 3b has a beam shape extending longer and away from the beam portion 3c in the base direction from the tip of the beam portion 3c of the locking portion 3a.

  Therefore, when the release operation portion 3b is pressed to the receiving port 1 side with the hand, the distal end side of the beam portion 3c of the locking portion 3a is bent outwardly within the elastic deformation range of the receiving port 1, and the protruding portion of the locking portion 3a The locking between 3d and the outer periphery of the corrugated protective tube that has been inserted can be released.

  In other words, the elastic locking operation unit 3 holds the protective tube in a state where it is prevented from coming off after the locking portion 3a is elastically deformed by insertion of the protective tube, and is elastically deformed by operation of the release operation unit 3b. Thus, it is configured to use elasticity that enables the locking portion 3a to be released from the retaining state.

  The abutting surface 4a of the fixing portion 4 is for bringing the connecting portion 2, that is, the protective tube connector 5, into contact with the wall surface W, that is, the surface to be fixed. This relationship may be such that there is no step on both surfaces as in this example, or there may be a step such as the relationship between the contact surface 4e in FIG. 5 and the outer peripheral surface of the connecting portion 2B.

  In other words, the abutting surface extends from the abutting side to the wall surface or the like of the connecting portion toward the wall surface, and may be any material suitable for attaching the protective tube connector to the wall surface or the like.

  The fixing hole 4b is for inserting a nail, a screw B or the like to fix the protective tube connector 5 to the wall surface W, and is not limited to one place as in this example. .

  A central partition projection 5a that contacts the outer peripheral side of the inserted protective tube is provided at the center of the inner peripheral wall of the receiving port 1 on both sides of the protective tube connector 5 provided with the connection port 2 facing the port. The protective tube is prevented from being inserted any further. The central partition projection 5a does not interfere with the insertion of the wiring / pipe material that is passed through the protective tube.

  The material of the protective tube connector 5 is preferably a flexible synthetic resin with good moldability, for example, an ABS (acrylonitrile butadiene styrene copolymer) resin.

  In particular, when a flame-retardant ABS resin is used as the material, it is possible to prevent the protected internal wiring / piping material from being affected by the fire in the event of a fire or the like.

  Further, since this ABS resin has appropriate mechanical strength and flexibility, the function of the elastic locking operation part 3 for achieving locking and unlocking of the protective tube inserted by the elasticity of the material is suitable. Guarantee that it will be demonstrated.

  Hereafter, the usage method of the protection tube connector 5 of the above structures, that is, the connection method for connecting the corrugated protection tube SP using the protection tube connector 5 will be described.

  2A and 2B illustrate a method of using the protective tube connector of FIG. 1, wherein FIG. 2A is a front view showing a state before connection, and FIG. (C) is a cross-sectional view showing a state in which the elastic locking operation portion is bent by a protective tube further inserted from (b), and (d) is a wavy state where insertion is completed.

  Even if it is attempted to pull out the corrugated protective tube SP in this state, the pull-out preventing portion 3f of the elastic locking operation portion 3 prevents the pull-out, and therefore cannot be pulled out.

  On the other hand, when the release operation portion 3b of the elastic locking operation portion 3 is pressed with the hand H, as shown in FIG. 2 (e), the locking portion 3a is bent to the outside of the receiving port 1, and the protrusion 3d at the tip thereof is It comes to be located outside the outer periphery of the protective tube SP, and the protective tube SP can be easily extracted, that is, disconnected.

  At this time, at least the elastic locking operation portion (locking operation portion) 3 is provided at a position other than the contact side to the wall surface W of the connection portion 2 as shown in FIG. The wall surface W does not become an obstacle to the operation.

  Further, since the protective tube connector 5 is fixed to the wall surface W or the like by the fixing portion 4, there is no need to separately fix the protective tube SP portion, and this fixing portion 4 can be protected tube even in a fixed state. There is no hindrance to SP connection and disconnection.

  Thus, according to this protective tube connector 5, the corrugated protective tubes SP disposed along the wall surface W and the like are connected to each other in a retaining state and can be fixed to the wall surface W. Even if it remains, the protection tube SP can be connected.

  Also, in this example, a locking operation that allows the protective tube inserted into the receiving port to be locked in a detachable state by moving in the radial direction and to release the lock. As an example of the part, the elastic locking operation part 3 including the locking part 3a using the elasticity and the release operation part 3b is shown, but the locking operation part is not limited to this.
