Description

  The present invention generally relates to a cable retainer used when a communication line such as an optical cable or a telephone line is drawn from a utility pole to a building.

  A fastener body (generally made of resin) that protrudes from a retaining ring (generally formed in an annular shape that forms a steel wire) that hooks on a receiving material (hook) provided on a building or utility pole. There is one in which a plurality of protrusions each having a collar piece at the tip are arranged in parallel on one side (for example, Patent Documents 1 and 2).

Japanese Utility Model Publication 3-47399 JP-A-10-288711

  In the conventional structure, a support wire is wound around a protrusion to hold a communication line (optical cable or telephone line). In the holding operation, the hard steel wire constituting the support wire is bent to make the protrusion. Since the work is complicated and complicated, it requires skill.

  The present invention has been devised for the purpose of providing a cable retainer capable of easily performing a retaining operation, paying attention to the drawbacks of such a conventional example.

  A fastener body provided at one end with a latching part that latches on a receiving material provided on a building or a utility pole, and a clamping piece that is fastened to each other by a bolt and a nut that is screwed onto the fastener body. It is set as the structure which provided the clamping groove | channel of the supporting line of a cable in the end along the longitudinal direction of the opposing surface of a clamping piece and the said holding | maintenance main body.

  According to the present invention, it is possible to perform a holding operation by simply pinching between a main body and a holding piece without bending and deforming a support wire, and therefore it is possible to provide a cable holding device that can easily perform a cable holding operation. can do.

  FIG. 1 is a front view, FIG. 2 is a bottom view, FIG. 3 is a left side view, and FIG. 4 is a sectional view taken along line aa in FIG. 5 is an exploded bottom view, FIG. 6 is a rear view of the clasp main body, FIG. 7 is a front view of the clamping piece, and FIG. 8 is a front view showing a use state.

  In the present invention, the holding device main body 1 and the holding piece 2 are overlapped with each other to hold the support wire 3a of the cable 3, and the holding state is held by the bolt 5 and the nut 6 screwed to the cable 3 to hold the cable 3 Is intended to be retained.

  The clasp main body 1 is provided with a fitting protrusion 4a formed by raising an intermediate portion of the surface 4 'facing the sandwiching piece 2, and at the end of the resin block body 4 in the longitudinal direction. A steel rod-made retaining rod 7 provided with an annular retaining portion 7a is provided to project. Then, at one end along the longitudinal direction of the block body 4, the holding groove 8 having a semicircular cross section for engaging the support wire 3 a of the cable 3 is recessed so as to be positioned at the base of the fitting protrusion 4 a. In the holding groove 8, locking protrusions 8 a that are long in the direction perpendicular to the longitudinal direction of the holding groove 8 are arranged in parallel along the longitudinal direction.

  Further, the opposed surface 4 ′ of the block body 4 and the outer surface 4 ″ opposite to the opposed surface 4 ′ are communicated with an intermediate portion in the longitudinal direction of the fitting projection 4 a of the block body 4. A pair of holes are arranged side by side along the longitudinal direction, one of which is a through hole 9 that is assembled by penetrating the bolt 5, and the other is a guide hole 10. A raised portion 11 surrounding the through hole 9 is provided around the side surface 4 ″ side, and the non-circular (hexagonal in the embodiment) head 5a of the bolt 5 communicating with the through hole 9 on the raised portion 11 is provided. The non-circular holes 11a that are engaged with each other are provided (these non-circular shapes can prevent the bolts from rotating together when the nut 15 is tightened).

  The clamping piece 2 is made of a synthetic resin body having the same width and the same length as the block body 4 of the clasp main body 1, and the fitting protrusion 4 a is fitted to the facing surface 2 ′ with the block body 4. A recess 2a is provided, and a clamping groove 12 having a semicircular cross section facing the clamping groove 8 of the block body 4 is provided on one side along the longitudinal direction, which is an edge of the fitting recess 2a, and the block body 4 side The holding groove 12 is provided with locking ridges 12a similar to the locking ridges 8a provided in the holding groove 8 along the longitudinal direction. is there.

  The locking ridges 8a and 12a are positioned so as to face each other when the block body 4 and the sandwiching piece 2 are overlapped, but are alternately arranged along the longitudinal direction of the block body 4 and the like. In addition, it is not necessary to limit to the embodiment. In short, unevenness is provided on the surface of the holding grooves 8 and 12, and the unevenness is partly in contact with the peripheral side of the support wire 3 a engaged between the holding grooves 8 and 12 and between the holding grooves 8 and 12. Any material that does not easily come off can be used.

  The clamping piece 2 is also provided with a through hole 13 at a position corresponding to the through hole 9 on the block body 4 side in the fitting recess 2a, and a guide rod 14 protruding at a position corresponding to the guide hole 10. It is.

  Then, the block body 4 and the sandwiching piece 2 of the clasp body 1 are opposed to each other on the facing surfaces 4 ′ and 2 ′, and the guide rod 14 on the sandwiching piece 2 side is inserted into the guide hole 10 on the block body 4 side. On the other hand, the bolt 5 is passed through the through-holes 9 and 13 matched with each other from the one through-hole 9 side, and the nut 15 is loosely screwed to the tip of the bolt 5 protruding from the other through-hole 13 side; (At this time, the block body and the clamping piece 2 are in a state where the bolt 5 and the guide rod 14 are combined in a so-called two-axis state, so that the block body and the holding piece 2 do not rotate around the axis and are in a stable combined state. In this state, when the support wire 3a of the cable 3 is interposed and engaged between the holding grooves 8 and 12, and the nut 15 is tightened, the block body 4 and the holding piece 2 come close to each other and the holding groove 3 8 and 12, the support wire 3a is sandwiched, and the retaining member is the support wire 3 In this state, the hooking portion 7a of the clasp body 1 is hooked to a predetermined receiving material (hook) 16 so that the cable 3 to the building h in which the receiving material 16 is installed can be connected. Retention work can be performed.

  The cable is an optical cable in which the support wire 3a, the optical fiber wires 3b and 3b, and the holding wire 3c are arranged and covered with a synthetic resin so as to be integrated. It is not necessary to limit the cable to only such a cable, but it is effective for retaining a so-called self-supporting cable. For example, it is applicable even when a cable is retained in combination with a support wire separate from the cable. There is no inconvenience.
