The signal cable insertion tool (10) of the present invention includes a cylindrical main body (20), a detent member (30) projecting outward from the outer periphery of the main body (20), and an inner periphery of the main body (20). A signal cable holding member (40) projecting inwardly.

  As a specific example, the main body (20) can be formed of a resin such as plastic, and can be exemplified by a cylindrical shape having an opening (22) on the base end side. The signal cable (60) is inserted from the opening (22) on the proximal end side.

  As shown in FIGS. 1 and 2, the tip of the main body (20) does not get caught in the through hole (70) (see FIG. 7 etc.) during the wiring work, and the signal cable insertion tool ( 10) It is desirable to reduce the diameter of the tip so that it can pass through. Further, it is desirable to close the tip in order to prevent dust from entering the inside of the main body (20) from the tip of the main body (20).

  As shown in FIGS. 1 to 3, the detent member (30) protrudes outward from the outer periphery of the main body (20) and has a shape that widens toward the base end side of the main body (20). It is desirable to do. The detent member (30) can be made of a flexible material. When the main body (20) is made of resin, it can be molded integrally with the main body (20).

  In the illustrated embodiment, the detent member (30) is inclined obliquely outward from the trunk portion near the proximal end of the main body (20) toward the proximal end, and the distal end extends substantially parallel to the main body (20). It has a different shape. In the embodiment shown in the figure, eight detent members (30) are formed, but the number is not limited to this. Further, for example, the detent member (30) can be formed in a skirt-like cylindrical shape that spreads outward toward the base end side of the main body (20).

  Formed so that at least a part of the outer periphery of the detent member (30) protrudes to contact the inner surface of the through hole (70) when the signal cable insertion tool (10) is passed through the through hole (70). It is desirable to do.

  As shown in FIGS. 2 and 3, the signal cable holding member (40) protrudes inward from the inner periphery of the main body (20). The signal cable holding member (40) can be made of a flexible material, and when the main body (20) is made of resin, it can be molded integrally with the main body (20).

  The signal cable holding member (40) is configured to project to the inner side of the outer diameter of the signal cable (60) through which it passes. The protruding end of the signal cable holding member (40) holds the signal cable (60) so that it does not easily come off (see FIG. 4).

  In the illustrated embodiment, the signal cable restraining member (40) is inclined inwardly from the inner surface of the base end of the main body (20) toward the distal end, and the distal end is bent outward. When the inserted signal cable (60) is removed from the signal cable insertion tool (10) by bending the tip outward, the signal cable (60) and connector (62) are attached to the signal cable restraining member (40). It can be prevented from being caught.

  In the embodiment shown in the figure, the number of signal cable holding members (40) is eight, but the number is not limited to this. In addition, for example, the signal cable holding member may be formed in a skirt-like cylindrical shape that decreases in diameter from the base end side to the tip end side of the main body (20).

  Furthermore, as shown in FIGS. 1 and 2, an annular hook member (50) can be formed at the tip of the main body (20). In this case, it is possible to easily perform the wiring work by previously passing a cable body such as a wire through the through hole (70), binding the cable body to the hook member (50), and pulling the cable body from the other. it can.

  Also, when the signal cable insertion tool (10) stops moving in the middle of the through hole (70), insert a jig with a hook-shaped tip and hook the jig on the hook member (50). The signal cable insertion tool (10) can be pulled out.

  A signal cable (60) is inserted into the signal cable insertion tool (10) configured as described above from the proximal end opening (22) of the main body (20) as shown by the arrows in FIGS. Since the signal cable holding member (40) protrudes inward from the signal cable (60), the signal cable (60) bends the signal cable holding member (40) outward as shown in FIG. Become. Thereby, the signal cable holding member (40) can hold the signal cable (60) firmly.

  As shown in FIGS. 1, 2 and 4, when the connector (62) is connected to the tip of the signal cable (60), the signal cable (60) is inserted into the main body (20) first. The connector (62) passes between the signal cable holding members (40), and then the signal cable (60) enters while bending the signal cable holding member (40) outward.

  In this specification, the signal cable (60) includes a cable for transmitting and receiving signals between devices and a cable for supplying power to the devices. Examples of the signal cable (60) include a single wire, a stranded wire, a coaxial cable, and an optical fiber. Moreover, the cable by which the signal cable was quad twisted may be sufficient as these.

  Further, it is desirable that the connector (62) is connected to the tip of the signal cable (60) so that the signal cable (60) can be easily electrically connected.

  As shown in FIG. 4, the signal cable insertion tool (10) is held in the signal cable insertion tool (10) and the signal cable insertion tool (10) is inserted into the wiring hole (70). It is.

  FIG. 5 is a sectional view of the vicinity of the shaft (72) of the elevator. As shown in the figure, the outer periphery of the shaft (72) is covered with a building wall (74), and the wall (74) has an opening (76) that serves as an entrance to and from the car. In the figure, a basket, an outer door, and the like are not shown.

  In the shaft (72), there is a signal cable (60) for electrically connecting the control panel for operating and controlling the car and the operation panel (78) and display device installed at the landing. As shown in FIG. 6, a plurality of signal cable groups (64) bundled by a binding band (66) or the like are arranged in the vertical direction along the shaft (72).

  As shown in FIG. 5, a through hole (70) is formed through the wall (74) of each landing. One or a plurality of signal cables (60) are drawn out from the signal cable group (64) as shown in FIG. 6, and the signal cable (60) passes through the through hole (70) as shown in FIG. Thus, it is electrically connected to an operation panel (78) installed outside the shaft (72).

  The wiring operation of the signal cable (60) using the signal cable insertion tool (10) of the present invention will be described with reference to FIGS. Note that a part of the signal cable insertion tool (10) is shown in cross section.

  First, as shown in FIG. 4 and FIG. 4, with the signal cable 60 attached to the signal cable insertion tool 10, the signal cable insertion tool 10 is routed as shown by the arrow in FIG. Insert into hole (70).

  After inserting the signal cable insertion tool (10) into the through hole (70), the signal cable insertion tool (10) is inserted into the through hole (70) by pushing the signal cable (60) into the through hole (70). Continue on 70). As shown in FIG. 8, when the tip of the signal cable insertion tool (10) protrudes from the through hole (70), the signal cable (60) is simply passed through the through hole (70). Can be passed through.

  Since the tip of the signal cable (60) is protected by the signal cable insertion tool (10), the signal cable (60) is not damaged. Even when the connector (62) is connected to the tip, the connector (62) is protected by the signal cable insertion tool (10), so it will not be damaged or get dusty. .

  The signal cable insertion tool (10) is provided with a detent member (30) even if the signal cable (60) is released during the wiring work or the signal cable (60) is pulled. Therefore, the detent member (30) is caught on the inner surface of the through hole (70) to prevent the signal cable (60) from returning, so that the signal cable wiring work efficiency can be increased as much as possible. it can.

  Therefore, the signal cable insertion tool (10) according to the present invention is particularly suitable for the work of passing through the through-hole (70) formed long because the wall (74) is thick, as shown in FIG. The elevator signal cable (60) for which sufficient space cannot be secured is suitable for use in wiring work.

  In order to further improve the wiring work efficiency, a cable or other cable body is passed through the through hole (70) in advance, and the cable body is tied to the hook member (50) at the tip of the signal cable insertion tool (10). The cable body may be pulled out from the other side.

  Also, when the signal cable insertion tool (10) stops moving in the middle of the through hole (70), insert a jig with a hook-shaped tip and hook the jig on the hook member (50). The signal cable insertion tool (10) can be pulled out.

  When the signal cable (60) completely penetrates the through hole (70), the signal cable insertion tool (10) and the signal cable (60) may be grasped and the signal cable insertion tool (10) may be pulled. Thereby, the holding state of the signal cable (60) by the signal cable holding member (40) is released, and the signal cable (60) is pulled out from the signal cable insertion tool (10), and as shown in FIG. The line work is completed.

  The signal cable (60) can be attached to and detached from the signal cable insertion tool (10) using a jig or the like.

  An example of such a jig is a jig that spreads the signal cable holding member (40) from the inside to the outside in a state where the signal cable (60) is inserted into the signal cable holding member (40).

  More specifically, the jig may include two semi-cylindrical resin materials whose inner diameters are larger than those of the signal cable (60) and the connector (62), and one of the long sides connected as a resin hinge. it can. When removing the signal cable (60) from the signal cable insertion tool (10), this jig fits one of the semicircular resin materials to the signal cable (60) and then attaches the other resin material to the signal cable ( Rotate to cover 60) to form a cylinder. In this state, the signal cable holding member (40) is expanded by pushing toward the signal cable holding member (40). Thereby, the signal cable (60) can be easily pulled out from the signal cable holding member (40).

  In addition, in order to make the signal cable (60) detachable from the signal cable insertion tool (10) without using a jig, for example, the signal cable insertion tool (10) itself is composed of a half body cut in the longitudinal direction. May be. When attaching the signal cable (60), the signal cable insertion tool (10) may be opened, pushed into the signal cable holding member (40) of one half, and covered with the other half. The halves can be locked so as to be opened and closed with, for example, a resin hinge, hook, screw, cap, rubber or string. When removing the signal cable (60), it is only necessary to release the latch and open the half.
