Description

[Technical field]

[0001] The present invention relates to a cable connector which is attached to the tip of a wire pulling tool for pulling in a lead wire or the like, and is connected to one end of a cable such as an optical drop cable for use in cable pulling operations. [Background technology]

[0002] Conventionally, cable connectors are used to pull cables such as optical drop cables that connect trunk cables stretched between utility poles and communication devices in buildings into buildings. As such cable connectors, for example, a cable connector has been proposed that includes a linear main body, a substantially spherical tip disposed at one end of the main body, and a connecting part that connects one end of the optical drop cable to the other end of the main body, the bending rigidity of the main body being smaller than that of the optical drop cable, and the length of the main body being 900 mm to 1200 mm (see, for example, Patent Document 1). This patent document describes that the connecting part and one end of the optical drop cable are connected using vinyl tape, a crimp sleeve, or the like. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2008-187762 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the cable connector described in the above-mentioned Patent Document 1 had a problem in that when vinyl tape was used to connect the connector to one end of the optical drop cable, the work of wrapping and peeling off the vinyl tape was time-consuming.

[0005] Also, when connecting with a crimp sleeve, the crimp sleeve is clamped with pliers or the like, the support wire portion is clamped with the crimp sleeve, and then the crimp sleeve is covered with a thermo-compression tube and heated to connect the optical drop cable and the cable connector. Therefore, the work of clamping with the crimp sleeve and heating with the thermo-compression tube is time-consuming, and when removing it, it is necessary to heat it again and expand the crimp sleeve with pliers or the like, which is very time-consuming and a large workload.

[0006] Therefore, the present invention has been made in consideration of the above problems, and aims to provide a cable connector that makes it easy to connect and detach a cable between a wire pulling tool and one end of a cable, and that can improve the work efficiency of cable pulling operations, etc. [Means for solving the problem]

[0007] In order to solve the above problems, the cable connector of the present invention is a cable connector that is attached to the tip of a wire pulling tool and to which one end of a cable is connected, the cable connector having a wire pulling tool connecting portion at the rear end to which one end of the wire pulling tool is connected and a cable one-end hook portion at the tip end to which one end of the cable is hooked, and a cable presser body that is provided on the outside of the cable connector body and presses one end of the cable hooked on the cable one-end hook portion from the side, The cable one-end hooking portion has a cable fold-back accommodating portion in which one end of the cable is folded back and accommodated, a cable hooking protrusion that is surrounded by the cable fold-back accommodating portion and protrudes and to which the folded back one end of the cable is hooked, and a side opening that exposes the sides of the one-end fold-back accommodating portion and the cable hooking protrusion. It is characterized by: In addition, in the cable connector of the present invention, the cable fold-back accommodating portion is formed to be wider as it approaches the wire pulling tool connection portion so as to increase the distance between the cables, and is curved and folded back to allow the folded-back portion of one end of the cable to pass through.The cable pressing body is arranged to be slidable in its axial direction relative to the connector main body, and is characterized in that when it slides to press one end of the cable from the side, it presses down the folded-back portion of one end of the cable. In addition, in the cable connector of the present invention, the cable presser is formed in a cylindrical shape through which the connector main body passes, and a locking claw is provided on its inner peripheral surface, while the outer peripheral surface of the connector main body is provided with a locking claw guide groove portion into which the locking claw of the cable presser fits to guide the movement of the cable presser relative to the connector main body, and the locking claw of the cable presser is guided by the locking claw guide groove portion so that when the cable presser covers and presses from the side one end of the cable hooked on the cable one end hook portion, the locking claw of the cable presser is engaged. Locking protrusion It is also characterized by the provision of: Furthermore, in the cable connector of the present invention, the cable holder is formed in a cylindrical shape through which the connector main body passes, and its inner surface is provided with a female threaded portion that screws into a male threaded portion provided on the outer circumferential surface of the connector main body, and the female threaded portion of the cable holder screws into the male threaded portion of the connector main body and moves to cover and press from the side one end of the cable hung on the cable one end hanging portion. Effect of the Invention

[0008] In the cable connector of the present invention, one end of a cable is inserted and hooked on the cable one-end hooking portion, and after the hooking, the cable one end hooked on the cable one-end hooking portion is held down by the cable presser so that it does not come off to the side, thereby making it possible to easily and quickly connect the cable pulling tool to the cable one end. Also, the cable one end can be removed from the cable one-end hooking portion by releasing the cable presser that has been holding down the cable presser. This facilitates the connection and disconnection of one end of the cable to the wire pulling tool, thereby improving work efficiency. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, first and second embodiments of the cable connector according to the present invention will be described with reference to the drawings. Note that the first and second embodiments described below are merely examples of the present invention, and the present invention is not limited to the following first and second embodiments, and can be modified as appropriate within the scope of the technical concept of the present invention.

[0011] Embodiment 1. <Configuration of the cable connector 1 according to the first embodiment of the present invention> The cable connector 1 of the first embodiment according to the present invention is a synthetic resin cable connector that is attached to the tip of a wire pulling tool 2 such as a lead wire and to which one end of an optical drop cable 3 is connected, and is composed of a connector body 11 and a cable presser 12, and may further include an adapter 13 if necessary. In other words, the adapter 13 is an additional component and is an optional configuration.

[0012] (Connector body 11) The connector body 11 has a wire pulling tool connection portion 11a at its rear end to which the tip end of the wire pulling tool 2 is connected, and a cable one-end hook portion 11b at its tip end to which one end of the optical drop cable 3 is hooked. On the outer peripheral surface between the wire pulling tool connection portion 11a and the cable one-end hook portion 11b, there are provided a locking claw guide groove portion 11c, a locking protrusion 11d when released, and a locking protrusion 11e when the cable is held down.

[0013] (Wiring tool connection part 11a) In many cases, the wire-pulling tool connecting portion 11a is provided with a wire-pulling tool side connecting portion 21 having a female thread portion (not shown) formed at the tip portion of the wire-pulling tool 2, and therefore a male thread portion 11a1 is provided in accordance with the female thread portion (not shown) of the wire-pulling tool side connecting portion 21. In the case of a wire-pulling tool side connecting portion 21' having a male thread portion 21a' formed at the tip portion as shown in Fig. 12(a) described later, the wire-pulling tool side connecting portion 11a is connected to the male thread portion 21a of the wire-pulling tool side connecting portion 21 via an adapter 13 having female thread portions 13a, 13b formed on both sides as shown in Fig. 12(b).

[0014] The cable one-end hooking portion 11b has a cable fold-back accommodating portion 11b1 in which one end of the optical drop cable 3 is folded back and accommodated, a cable hooking protrusion 11b2 that is surrounded by the cable fold-back accommodating portion 11b1 and protrudes to hook one end of the folded back optical drop cable 3, and a side opening 11b3 that exposes the sides of the cable fold-back accommodating portion 11b1 and the cable hooking protrusion 11b2.

[0015] The cable fold-back accommodating section 11b1 is a passage for passing one end of the optical drop cable 3 folded back in a U-shape, and is formed in a U-shape, with a side opening 11b3 exposing the upper side, which is the side of the cable fold-back accommodating section 11b1 in Figure 4(a).

[0016] The cable hooking protrusion 11b2 is surrounded by the cable fold-back accommodating portion 11b1 formed in a U-shape and protrudes from the connector body 11. The closer it is to the wiring tool connection portion 11a, the wider it becomes so as to increase the distance between the optical drop cables 3 at the tip cable hooking protrusion 11b2 of the optical drop cables 3.

[0017] The side opening 11b3 is an opening that exposes the cable fold-back accommodating portion 11b1 and the cable one end hanging portion 11b from the side (top in Figures 3 and 4) of the connector main body 11, exposing the cable fold-back accommodating portion 11b1 and the cable one end hanging portion 11b.

[0018] The locking claw guide groove portion 11c is provided in the axial direction (longitudinal direction) of the connector body 11 on the outer peripheral surface between the wire-passing tool connecting portion 11a and the cable one-end hook portion 11b, and is a groove portion into which the locking claw 12b of the cable holder 12 fits to guide the axial (longitudinal) movement of the cable holder 12 relative to the connector body 11, thereby guiding the cable holder 12 between the locked state and the released state relative to the connector body 11.

[0019] The release-time locking protrusion 11d is provided within the locking claw guide groove portion 11c so as to protrude toward the wire pulling tool connection portion 11a, and is a locking protrusion that, when the locking claw 12b of the cable holder 12 is locked, opens the cable holder 12 to a detachable state without covering the side opening 11b3 and without holding down one end of the folded-back optical drop cable 3 from the side, relative to the cable hanging protrusion 11b2.

[0020] The projection 11e for retaining the cable when it is held down is provided on the side of the cable one-end hook portion 11b within the locking claw guide groove portion 11c, and is a projection for retaining the cable when the locking claw 12b of the cable holder 12 is engaged as shown in FIG. 2(a), so that the cable holder 12 covers approximately 1 / 2 of the side opening 11b3 and holds down one end of the folded-back optical drop cable 3 from the side so that it cannot fall off.

[0021] (Cable holder 12) The cable presser 12 is made of synthetic resin and formed into a cylindrical shape as shown in Figures 5 and 6, just like the connector body 11. It is attached to the outside of the connector body 11 and covers one end of the optical drop cable 3, which is hung on the cable one-end hanging portion 11b, from the outside, and is folded back to prevent the one end from coming off to the side, or slides to a removable state. The cable presser 12 has a connector body passing portion 12a1 through which the connector body 11 passes, and a pair of locking claws 12b, 12b are provided by making cuts 12c, 12c of a predetermined width in the axial direction of the connector body 12a so as to face the axial center of the connector body 12a.

[0022] Since the cable holding body 12 is formed from synthetic resin, when the pair of locking claws 12b, 12b come into contact with the locking projection 11d for locking when released or the locking projection 11e for locking when holding the cable, they are configured to elastically deform and lock into the locking projection 11d for locking when released or the locking projection 11e for locking when holding the cable.

[0023] <Operation etc. of the cable connector 1 according to the first embodiment of the present invention> Next, the operation of the cable connector 1 according to the first embodiment of the present invention configured as above will be described with reference to the drawings.

[0024] First, as shown in FIG. 6, both ends of a spiral hanger 7 are fixed by hanger end clamps 6 to a support wire 5, such as a steel strand, suspended between utility poles 4. In order to pass an optical drop cable 3 (not shown in FIG. 6) through the spiral center of the spiral hanger 7 and pull it into a building, a worker connects a well-known shuttle runner 8 to the wire-pulling tool side connector 21 at the tip of a wire-pulling tool 2, such as a lead wire, and moves the shuttle runner 8 connected to the tip of the wire-pulling tool 2, such as a lead wire, toward one end of the optical drop cable 3.

[0025] When the shuttle runner 8 connected to the tip of the wire pulling tool 2 for pulling a lead wire or the like is moved to the vicinity of one end of the optical drop cable 3, the shuttle runner 8 is removed from the wire pulling tool side connecting part 21 at the tip of the wire pulling tool 2 as shown in Figure 7, and the cable connector 1 of embodiment 1 is connected to the wire pulling tool side connecting part 21 as shown in Figure 8(a).

[0026] In this state, the pair of locking claws 12b, 12b of the cable holding body 12 have slid toward the wire pulling tool side connection portion 21 at the tip of the wire pulling tool 2, and the pair of locking claws 12b, 12b of the cable holding body 12 are engaged with the release-time locking protrusion 11d of the connector main body 11 (see Figures 1 and 2, etc.).

[0027] Next, the worker folds back one end of the optical drop cable 3, and through the side opening 11b3 of the connector body 11 of the cable connector 1, stores the folded back end of the optical drop cable 3 in the cable fold back storage portion 11b1 and engages it with the cable hanging protrusion 11b2, as shown in Figure 8 (b).

[0028] Although this allows the tip of the optical drop cable 3 to be easily hooked onto the connector body 11 of the cable connector 1, the side opening 11b3 of the connector body 11 is open as shown in FIG. 8(b), so that the cable is likely to fall off.

[0029] Therefore, the cable presser 12 is slid in the direction of the arrow toward the optical drop cable 3. Then, the pair of locking claws 12b, 12b of the cable presser 12 climb over the locking projections 11d, 11d for locking when released of the connector body 11 and slide toward the optical drop cable 3 along the locking claw guide groove 11c, and the cable presser 12 stops when it is locked by the locking projections 11e, 11e for locking when the cable is held, as shown in Fig. 8(c).

[0030] Therefore, as shown in Figure 8 (c), the cable holder 12 covers approximately 1 / 2 to 1 / 3 of the side opening 11b3 of the connector main body 11, and laterally covers approximately 1 / 2 to 1 / 3 of the folded back end of the optical drop cable 3 that is accommodated in the cable fold-back accommodating portion 11b1 and hooked onto the cable hooking protrusion 11b2, thereby making it possible to easily connect the optical drop cable 3 to the cable connector 1 in a non-detachable state.

[0031] This allows the lead wire or other wiring tool 2 to be easily and quickly connected to one end of the optical drop cable 3 via the cable connector 1 of the first embodiment by simply sliding the cable holder 12, as shown in FIG.

[0032] Then, as shown in FIG. 10, the worker pulls the wire pulling tool 2 such as a lead wire in the direction of the arrow, which is toward the building, to pull one end of the optical drop cable 3 close to the building, and then, as shown in FIG. 11, removes the wire pulling tool 2 such as a lead wire from the cable connector 1 of embodiment 1, and then removes the cable connector 1 of embodiment 1 from one end of the optical drop cable 3 and connects one end of the optical drop cable 3 to a drop wire (not shown) extending from the building, thereby completing the work.

[0033] In the above explanation, it is described that a female thread portion (not shown) is formed on the wire pulling tool side connecting portion 21 provided at the tip of the wire pulling tool 2 for example, such as a lead wire. However, if a male thread portion 21a' is formed on the wire pulling tool side connecting portion 21' provided at the tip of the wire pulling tool 2 for example, such as a lead wire, as shown in Figure 12(a), then the wire pulling tool connecting portion 11a of the cable connector 1 of embodiment 1 also has a male thread portion 11a1 formed thereon, and therefore the connecting portion main body 11 of the cable connector 1 cannot be directly connected to the wire pulling tool side connecting portion 21' of the wire pulling tool 2.

[0034] Therefore, for example, as shown in Figure 12(b), the connecting portion main body 11 of the cable connecting device 1 and the connecting portion 21 of the wire pulling tool 2 are connected to each other via an adapter 13 having female threaded portions 13a, 13b formed on both sides, i.e., the male threaded portion 11a1 of the wire pulling tool connecting portion 11a of the cable connecting device 1 screws into the female threaded portion 13a of the adapter 13, while the male threaded portion 21a' of the wire pulling tool side connecting portion 21' of the wire pulling tool 2 screws into the female threaded portion 13b of the adapter 13.

[0035] <Summary of the cable connector 1 according to the first embodiment of the present invention> As described above, the cable connector 1 of embodiment 1 of the present invention has a connector body 11 having a wire pulling tool connecting portion 11a at its rear end to which the wire pulling tool side connecting portion 21 of the wire pulling tool 2 is connected, and a cable one end hooking portion 11b at its front end to which one end of the optical drop cable 3 is hooked from the side opening 11b3, and a cable holder 12 that is attached to the outside of the connector body 11 and covers from the outside one end of the optical drop cable 3 that is folded back so that the one end of the optical drop cable 3 hooked on the cable one end hooking portion 11b does not come off to the side.

[0036] Therefore, one end of the optical drop cable 3 is inserted through the side opening 11b3 and hooked onto the cable one-end hooking portion 11b, and after hooking, the side opening 11b3 is covered with the cable holder 12 to prevent the one end of the optical drop cable 3 hooked onto the cable one-end hooking portion 11b from coming off to the side, thereby making it possible to easily and quickly connect the wire pulling tool 2 to the one end of the optical drop cable 3. At the same time, the cable holder 12 covering the side opening 11b3 and the cable one-end hooking portion 11b is shifted to release the one end of the optical drop cable 3 from the cable one-end hooking portion 11b, thereby allowing the one end of the optical drop cable 3 to be removed.

[0037] As a result, the operation of connecting and disconnecting one end of the optical drop cable 3 to the wiring tool 2 can be performed easily and quickly, thereby improving the work efficiency.

[0038] In addition, in the cable connector 1 of embodiment 1 according to the present invention, the cable one-end hooking portion 11b has a cable fold-back accommodating portion 11b1 in which one end of the folded-back optical drop cable 3 is accommodated, and a cable hooking protrusion 11b2 which is surrounded by and protrudes from the cable fold-back accommodating portion 11b1 and in which one end of the folded-back optical drop cable 3 is hooked, and the cable hooking protrusion 11b2 is formed so as to become wider as it approaches the wiring tool connection portion 11a so as to increase the distance between the optical drop cables 3 at the tip cable hooking protrusion 11b2 of the optical drop cables 3.

[0039] Therefore, according to the cable connector 1 of embodiment 1 of the present invention, one end of the folded optical drop cable 3 can be easily accommodated in the cable fold-back accommodating portion 11b1 and can also be easily hooked onto the cable hooking protrusion 11b2, thereby improving work efficiency in this respect as well.

[0040] In addition, in the cable connector 1 of embodiment 1 according to the present invention, the cable holder 12 is provided with an engagement claw 12b, while the outer peripheral surface of the connector main body 11 is provided with an engagement claw guide groove portion 11c into which the engagement claw 12b of the cable holder 12 fits to guide the movement of the cable holder 12 relative to the connector main body 11, and a cable holding engagement protrusion 11e with which the engagement claw 12b of the cable holder 12 engages when the cable holder 12 covers and presses one end of the optical drop cable 3 hooked on the cable one end hook portion 11b from the side.

[0041] Therefore, according to the cable connector 1 of embodiment 1 of the present invention, by simply sliding the cable holder 12 along the locking claw guide groove portion 11c, the one end of the optical drop cable 3 hooked to the cable one-end hook portion 11b can be covered from the side, thereby easily and quickly connecting the wire pulling tool 2 to the one end of the optical drop cable 3, and the one end of the optical drop cable 3 can be removed by releasing the one end of the optical drop cable 3 from the cable one-end hook portion 11b, so that the connection and removal operations of the one end of the optical drop cable 3 to the wire pulling tool 2 can be performed easily and quickly, thereby improving work efficiency.

[0042] Embodiment 2. <Cable connector 1′ according to embodiment 2 of the present invention> In the cable connector 1 of the above-mentioned embodiment 1, a locking claw 12b is provided on the cable holder 12, and the locking claw 12b is guided by the locking claw guide groove portion 11c on the outer circumferential surface of the connector body 11 and slides to cover approximately 1 / 2 to 1 / 3 of the side of one end of the optical drop cable 3 hooked to the cable one-end hook portion 11b, or is opened to fix or remove one end of the optical drop cable 3. However, the cable connector 1' of embodiment 2 is characterized in that the cable holder 12 is configured to be slidable in its axial direction relative to the connector body 11 by the male thread portion 11f' and the female thread portion 12a'.

[0043] Figure 13 is a perspective view of a cable coupler 1' of embodiment 2, Figures 14(a) to (d) are a front view, left side view, right side view and plan view of a cable coupler 1' of embodiment 2 according to the present invention, Figure 15 is a perspective view of a coupler main body 11' constituting the cable coupler 1' of embodiment 2, Figures 16(a) to (d) are a front view, left side view, right side view and plan view of the coupler main body 11', and Figures 17(a) to (e) are a perspective view, front view, left side view, right side view and a cross-sectional view along line BB of a cable presser body 12' constituting the cable coupler 1' of embodiment 2.

[0044] 13 and 14, the connector body 11' constituting the cable connector 1' of the second embodiment is different from the connector body 11 constituting the cable connector 1 of the first embodiment in that it has a male thread 11f' instead of the locking claw guide groove 11c, the release locking projection 11d, and the cable locking projection 11e, while the cable holder 12' is configured to screw into the male thread 11f' of the connector body 11, slide in the axial direction of the connector body 11, and cover from the outside one end of the optical drop cable 3 that is hooked on the cable one-end hooking portion 11b' so that the one end of the optical drop cable 3 is not dislodged to the side. The connector body 11' and the cable holder 12' constituting the cable connector 1' of the second embodiment are manufactured by cutting out a metal such as brass.

[0045] Therefore, on the inner surface of the cable holder 12' constituting the cable connector 1' of embodiment 2, there is provided a female threaded portion 12a' which screws into the male threaded portion 11f' of the connector main body 11', and a cable holder 12b' which covers and holds one end of the folded-back optical drop cable 3 from the outside, as shown in Figures 17(a) to (e).

[0046] The configuration other than the male thread portion 11f' of the connector body 11' and the female thread portion 12a' of the cable presser 12' is the same as that of the cable connector 1 of the first embodiment, and therefore description thereof will be omitted.

[0047] Therefore, in the cable connector 1' of embodiment 2, the worker folds back one end of the optical drop cable 3, and then, as shown in Figure 18(a), stores the folded back one end of the optical drop cable 3 in the cable fold back storage portion 11b1 through the side opening 11b3' of the connector body 11' of the cable connector 1', engages it with the cable hanging protrusion 11b2, and then rotates the cable holder 12'.

[0048] Then, since the female threaded portion 12a' of the cable holder 12' is screwed into the male threaded portion 11f' of the connector body 11', the cable holder 12' slides toward the optical drop cable 3, covering approximately 1 / 2 to 1 / 3 of the side opening 11b3' of the connector body 11' and covering approximately 1 / 2 to 1 / 3 of the folded back end of the optical drop cable 3 that is housed in the cable fold-back housing portion 11b1' and hooked on the cable hooking protrusion 11b2' from the side, thereby easily connecting the optical drop cable 3 to the cable connector 1 in a non-detachable state.

[0049] As a result, as in the case of the cable connector 1 of embodiment 1, as shown in Figure 8, a wire pulling tool 2 such as a lead wire and one end of an optical drop cable 3 can be easily and quickly connected by simply sliding the cable holder 12.

[0050] <Summary of the cable connector 1' according to the second embodiment of the present invention> Therefore, the cable connector 1' of embodiment 2 according to the present invention, like the cable connector 1 of embodiment 1, has a wire pulling tool connecting portion 11a' at the rear end to which the wire pulling tool side connecting portion 21 of the wire pulling tool 2 is connected, and has a connector body 11 having a cable one end hanging portion 11b' at the front end to which one end of the optical drop cable 3 is hung from the side opening 11b3'.This makes it easy and quick to connect and disconnect one end of the optical drop cable 3 to the wire pulling tool 2, thereby achieving effects such as improved work efficiency.

[0051] In particular, in the cable connector 1' of embodiment 2 of the present invention, the inner surface of the cable holder 12' is provided with a female threaded portion 12a' which screws into the male threaded portion 11f' provided on the outer surface of the connector main body 11', and the female threaded portion 12a' of the cable holder 12' screws into the male threaded portion 11f' of the connector main body 11 and moves to cover and press one end of the optical drop cable 3 hooked on the cable one-end hook portion 11b' from the side.Although this takes more time than the locking claw guide groove portion 11c, the release locking protrusion 11d, and the cable locking protrusion 11e of the cable connector 1 of embodiment 1, the male threaded portion 11f' and the female threaded portion 12a' can be screwed together to connect one end of the optical drop cable 3 more reliably.

[0052] Incidentally, the cable connector 1 of the above embodiment 1 has been described as being made of resin, and the cable connector 1' of the above embodiment 2 has been described as being made of metal such as brass or aluminum, however, the present invention is not limited to this, and it is of course also possible to manufacture the cable connector 1 of the above embodiment 1 from metal and the cable connector 1' of the above embodiment 2 from resin, and there is no particular restriction on the materials used for the cable connectors 1, 1' of the above embodiments 1 and 2.

[0053] In addition, in the cable connectors 1, 1' of the cable connectors 1, 2 of embodiments 1, 2, the cable holders 12, 12' are configured to be cylindrically shaped and slide to cover and press one end of the optical drop cable 3 hooked to the cable one-end hooking portion 11b, 11b' from the side, but the present invention is not limited to such cylindrically shaped and sliding cable holders 12, 12', and may of course be configured to cover and press or release one end of the optical drop cable 3 hooked to the cable one-end hooking portion 11b, 11b' from the side by a lever or the like whose base is rotatably provided on the side of the connector main body 11, 11'.

[0054] In addition, in the explanation of the cable connectors 1 and 2 of the first and second embodiments, an optical drop cable 3 having an optical cable as the core wire has been used as an example of the cable, but the present invention is not limited to this, and it may of course be used to connect cables other than drop cables, such as optical drop cables.
