Description

  The present invention relates to a cable support for suspending a cable from a messenger wire and an end connector thereof.

  Conventionally, when a cable is suspended and fixed to a messenger wire suspended between utility poles, a method in which a helical cable support is connected and fixed to the messenger wire in sequence and suspended is used. The supporting tool used is a connecting tool made of an aluminum cylindrical body, the ends of the supporting tools to be connected are inserted into the connecting tool, and the part is crushed with a crushing tool. Are fixed.

However, in the conventional method, the connecting tool and the support tool must be handled separately, and further, the fixing of the connecting part has to use a crushing tool.

  Hereinafter, the present invention will be described in detail with reference to the best mode for carrying out the invention shown in the drawings.

  In the first preferred embodiment for carrying out the present invention shown in FIGS. 1 to 17, reference numeral 1 denotes a cable support for suspending a cable 2 on a messenger wire 3, and the cable support 1 is a messenger wire. 3, a helical cable support body 4 that can be hung from the cable 3, and the cable 2 can be arranged on the inner side thereof, and a fixed base 5 that is caulked and fixed to one end of the cable support body 4. A female connector 7 formed by bending a metal plate, which is formed integrally with the distal end portion of the base 5 and has a cylindrical or substantially cylindrical inserted portion 6 in this embodiment; A fixed base 8 that is caulked and fixed to the other end of the cable support body 4, and an inserted portion 6 of the female connector 7 that is integrally formed at the distal end of the fixed base 8 in the axial direction. Insert at any angle A male connector 10 formed by bending a metal plate, and an engagement portion formed in the inserted portion 6 of the female connector 7. It is comprised with the fixing means 13 which consists of the joint protrusion 11 and the cyclic | annular engagement recessed part 12 formed in the insertion part 6 of the said male connection tool 10. FIG.

  As shown in FIGS. 1 and 2, the cable support body 4 is coated with a black polyethylene resin layer 15 for the purpose of anticorrosion on a core material 14 made of steel wire with a high-purity galvanized layer 14a. The surface that is formed in such a manner as to contact the messenger wire 3 or the like is configured to be a substantially flat surface 4a.

  As shown in FIGS. 3 to 9, the female connector 7 is formed using a metal having a strength sufficient to maintain the connection state with the male connector 10, for example, a stainless alloy. In addition, the female connector 7 is formed in a substantially cylindrical shape having a notch portion 7 a, whereby the male connector 10 is connected when the male connector 10 is connected, that is, the engagement formed in the inserted portion 6. When the male connector 10 passes over the mating protrusion 11, the male connector 10 is configured to be elastic enough to cause a slight deflection outward.

  As shown in FIGS. 10 to 15, the male connector 10 is formed in a cylindrical shape with the same material as the female connector 7. In addition, the process for tapering the said front-end | tip part by the cutting of three places is given to the front-end | tip part, for example.

As shown in FIG. 17 and the like, the fixing means 13 is formed by press molding or the like so that the engaging protrusion 11 protrudes into the inserted portion 6 of the female connector 7. The male connector 10 is formed near the tip of the male connector 10. Note that the fixing means 13 is in a smooth insertion state when the male connector 10 is connected to the female connector 7 and is not easily detached after connection. You may comprise by making the shape of the joint protrusion 11 into a wedge shape.
The female connector 7 and the male connector 10 to which such fixing means 13 are applied serve as an end connector of the cable support.

  As shown in FIG. 16, the cable support 1 having the above configuration is wound around and attached to a messenger wire 3 previously stretched between utility poles (not shown), and sent out in the direction of construction, and then the next cable support 1 female connector 7 (male connector 10) and the male connector 10 (female connector 7) of the previous cable support 1 are connected and connected.

  In this case, since the male connector 10 can be inserted into the female connector 7 at an arbitrary angle in the axial circumferential direction, the male connector 10 can be easily and easily affected by factors such as twisting of the cable support body 4. It can be connected.

  Such operations are repeated, and when a plurality of cable supports 1 are disposed between the utility poles, the end portions of the first cable support 1 and the last cable support 1 are fixed to each other by a fixing bracket (not shown). After fixing to the messenger wire 3 or the like, the cable 2 is inserted into the spiral of the cable support body 4 and extended.

  Unlike the prior art, the cable support 1 used in this way is only required to be connected by the male connector 10 and the female connector 7, so that the operation can be performed very easily.

  Further, since the female connector 7 and the male connector 10 are both formed by bending a metal plate, for example, unlike the case of cast molding, it is not necessary to use a complicated mold or the like. Therefore, the manufacturing cost can be reduced.

{Different forms for carrying out the invention}

  Next, different modes for carrying out the present invention shown in FIGS. 18 to 39 will be described. In the description of these different modes for carrying out the present invention, the same components as those in the best mode for carrying out the present invention are designated by the same reference numerals and redundant description is omitted. To do.

Even with the cable support 1 </ b> A using the fixing means 13 </ b> A composed of the above, the same operational effects as those of the best first embodiment for carrying out the present invention can be obtained.

  The third embodiment for carrying out the present invention shown in FIGS. 26 to 31 is mainly different from the best first embodiment for carrying out the present invention in that the insertion portion is formed in a cylindrical shape. The female connector 7B constituting 6A is used, and a plurality of notch grooves 15 are formed in the longitudinal direction of the tip, and the male connector 10B is provided with elasticity so as to be slightly bent in the axial direction. Even in the cable support 1B that constitutes the male connector 10B and the female connector 7B, the same effects as those of the best mode for carrying out the present invention can be obtained.

  The fourth embodiment for carrying out the present invention shown in FIGS. 32 to 39 differs from the best first embodiment for carrying out the present invention mainly in the insertion portion of the female connector 7C. An engaging projection 11B formed by forming a plurality of grooves in the longitudinal direction in 6A is formed, and an engaging recess 12 is formed in the engaging projection 11B in the inserted portion 6A of this female connector 7C. The male connector 10C that is not connected to the cable support 1C using the female connector 7C and the male connector 10C is configured so that the male connector 10C can be press-fitted so as not to be detached. The same effects as those of the best first embodiment for carrying out the invention can be obtained.

  In each of the embodiments for carrying out the present invention, the female connector 7 and the male connector 10 have been described by bending a metal plate. However, the present invention is not limited to this. Alternatively, it may be formed of a plastic material or the like. In this case, since the female connector 7 and the male connector 10 have simple shapes, the shape of the mold serving as a mold can be simplified, and the manufacturing cost can be sufficiently considered.

  In each embodiment for carrying out the present invention, the cable support body 4 is formed by coating a core material 14 made of a steel wire subjected to high-purity galvanization with a black polyethylene resin. Although demonstrated, this invention is not restricted to this, What kind of structure may be sufficient if it is a thing of the aspect which has intensity | strength and workability required in order to suspend the cable 2 to the messenger wire 3. FIG.

  The present invention is utilized in industries that produce cable supports and end fittings for suspending cables from messenger wires.
