Description

Technical Field

[0001] This utility model relates to the field of suspension hardware string technology, specifically an extended optical cable single-coupled double-line clamp suspension hardware string. Background Technology

[0002] A single-pair double-wire clamp suspension hardware string for optical cables is a metal accessory used to fix and protect optical cables. It is mainly used to suspend the optical cable from poles and towers, bearing the vertical load of the cable. It is widely used in various power and communication lines, effectively supporting and protecting the optical cable and ensuring its stable operation.

[0003] Existing conventional optical cable clamp strings have a relatively limited scope of application, mainly suitable for fixing and protecting optical cables in standard spans and ordinary environments. Their use has certain limitations, and in special environments, such as heavy icing areas, their mechanical strength and protective performance may be insufficient, potentially leading to reduced operational safety and reliability of the optical cable, making them inconvenient to use. Therefore, we propose an extended optical cable single-pair double-clip suspension clamp string. Utility Model Content

Their use has certain limitations, and in special environments, such as heavy icing areas, their mechanical strength and protective performance may be insufficient, which may lead to a reduction in the safety and reliability of optical cable operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An extended optical cable single-pair double-clamp suspension hardware string includes a trunnion mounting plate.

A ZBD mounting plate is bolted to the bottom of the PD mounting plate. A second right-angle mounting plate is bolted to the bottom of the ZBD mounting plate. A connecting plate is bolted to the bottom of the second right-angle mounting plate. Pre-twisted double-suspension clamps are symmetrically bolted to the bottom of the connecting plate. A cable is placed inside each pre-twisted double-suspension clamp. A parallel groove clamp for use with the cable is located on the outside of the cable. A grounding wire is placed inside the parallel groove clamp. The pre-twisted double-suspension clamps support the cable, avoid stress concentration, reduce the risk of cable damage, and thus provide good protection for the cable.

[0007] Preferably, the first right-angle mounting plate and the second right-angle mounting plate have the same specifications. The same specifications of the accessories mean that different parts can be interchanged, which improves the maintainability and durability of the equipment.

[0009] Preferably, the bolt has a slot inside, and a limit pin is detachably connected inside the slot. The limit pin can prevent the bolt and the connector from separating, thereby increasing the safety of the connection.

[0010] Preferably, the outer side of the limiting pin is provided with an arc-shaped protrusion, which can prevent the limiting pin from disengaging from the inside of the slot.

[0011] Preferably, the pre-stranded double suspension clamp is made of forged aluminum alloy, which has the advantages of being lightweight, high-strength, and corrosion-resistant, thus improving the service life of the pre-stranded double suspension clamp.

[0012] This utility model provides an extended single-pair double-clip suspension hardware string for optical cables. Compared with the prior art, it has the following advantages: This extended single-pair double-clip suspension hardware string for optical cables, by increasing the length of the clamps, can better support and fix the cables.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 3 This utility model provides a technical solution:

[0019] The extended optical cable single-pair double-clamp suspension hardware string includes a trunnion mounting plate 1. A first right-angle mounting plate 2 is bolted to the bottom of the trunnion mounting plate 1. A PD mounting plate 3 is bolted to the bottom of the first right-angle mounting plate 2. A ZBD mounting plate 4 is bolted to the bottom of the PD mounting plate 3. A second right-angle mounting plate 10 is bolted to the bottom of the ZBD mounting plate 4. A connecting plate 5 is bolted to the bottom of the second right-angle mounting plate 10. Pre-twisted double-suspension clamps 6 are symmetrically bolted to the bottom of the connecting plate 5. A cable 9 is placed inside the pre-twisted double-suspension clamps 6. The outer side is equipped with a parallel groove clamp 7 for use with it, and the grounding wire 8 is placed inside the parallel groove clamp 7. The parallel groove clamp 7 can connect the grounding wire 8 and the cable 9 together to ensure smooth current transmission, effectively prevent the wire from loosening and slipping, and ensure a stable connection. The pre-twisted double suspension clamp 6 can support the cable 9. The combination of the inner and outer spiral pre-twisted wires of the pre-twisted double suspension clamp 6 can effectively disperse the stress on the cable 9, avoid stress concentration, reduce the risk of damage to the cable 9, and thus play a good protective role for the cable 9.

[0020] Furthermore, the first right-angle mounting plate 2 and the second right-angle mounting plate 10 have the same specifications. The same specifications of accessories mean that different parts can be interchanged, which improves the maintainability and durability of the equipment.

[0021] Furthermore, each bolt is provided with a nut 12 on its outer side for use with it. The nut 12 can be used with the bolt to facilitate the assembly of the device.

[0022] Furthermore, the bolt has a slot 14 inside, and a limit pin 11 is detachably connected inside the slot 14. The limit pin 11 can prevent the bolt and the connector from separating, increasing the safety of the connection. When the limit pin 11 is inserted into the slot 14, the two ends of the limit pin 11 are pushed together, so that the limit pin 11 can pass through the slot 14. After passing through, the two ends of the limit pin 11 are released, and the limit pin 11 will move and reset due to elasticity, and then be placed inside the slot 14.

[0023] Furthermore, the outer side of the limiting pin 11 is provided with an arc-shaped protrusion 13, which can prevent the limiting pin 11 from disengaging from the inside of the slot 14.

[0024] Furthermore, the pre-stranded double suspension clamp 6 is made of forged aluminum alloy, which has the advantages of being lightweight, high-strength, and corrosion-resistant, thus improving the service life of the pre-stranded double suspension clamp 6.

[0025] Working principle:

[0026] In use, the grounding wire 8 and the cable 9 can be connected together by the parallel groove clamp 7, ensuring smooth current transmission, effectively preventing wire loosening and slippage, and ensuring a stable wire connection. The pre-twisted double suspension clamp 6 can support the cable 9. The combination of inner and outer spiral pre-twisted wires in the pre-twisted double suspension clamp 6 can effectively disperse the stress on the cable 9, avoid stress concentration, reduce the risk of damage to the cable 9, and thus provide good protection for the cable 9 and facilitate its use.
