Outdoor optical cable lightning protection rackTechnical field
The utility model relates to optical cable machine cabinet technical field, particularly relates to a kind of outdoor optical cable lightning protection rack.
Background technology
Outdoor cabinet is generally all arranged on remoter position, much in high mountain minefield, has installed very important communication facilities in rack, require very high for lightning protection, the approach that thunder and lightning is introduced has three approach usually, and one is steel tower itself, has independent steel tower lightning protection measures in communication engineering.Second is that power supply line can may introduce thunder and lightning, A level and the lightning protection of B level can be done separately in communications equipment room, the third may be incorporated into thunder and lightning in machine room/rack is exactly optical cable, optical cable itself is nonconducting insulator, but the intensity of optical fiber own is very poor, together with general meeting meets with metal steel wire, this steel wire serves the effect strengthening physical strength, and also handlebar thunder and lightning introduces the hidden danger of machine room/rack simultaneously.
Given this, the defect overcome existing for the prior art is the art problem demanding prompt solution.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of outdoor optical cable lightning protection rack, solves in prior art because optical cable employs technical matters thunder and lightning being introduced rack that metallic strength member causes.
The utility model adopts following technical scheme:
A kind of outdoor optical cable lightning protection rack, for carrying out lightning protection to the optical cable wire harness with metallic strength member, this lightning protection rack comprises:
Equipment compartment;
Be positioned at the lightning protection storehouse bottom equipment compartment; And
Be located in described lightning protection storehouse, with the lightning proof ground of the casing insulation of this lightning protection rack and arrange, described lightning proof ground row has at least one cable fixed part;
The described optical cable wire harness with metallic strength member is divided into metallic strength member and optical cable fibre core at tail end, and described optical cable fibre core stretches into equipment compartment from the perforate at top, lightning protection storehouse, and described metallic strength member is arranged by cable fixed part ground connection.
Preferably, described cable fixed part comprises a through wires hole and a wire harness clip gripping members.
Preferably, be also provided with one between described equipment compartment and described lightning protection storehouse for fixing the fixed bin of described optical cable fibre core, the static line be provided with in described fixed bin for fixing optical cable fibre core is arranged.
Compared with prior art, the beneficial effects of the utility model are: lightning protection mechanism of the present utility model is provided with lightning protection storehouse in the bottom of equipment compartment, optical cable wire harness is divided into metallic strength member and optical cable fibre core at tail end, optical cable fibre core stretches into equipment compartment from the perforate at top, lightning protection storehouse, metallic strength member is arranged by cable fixed part ground connection, effectively achieves the lightning protection of metallic strength member ground connection.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of outdoor optical cable lightning protection rack that the utility model embodiment 1 provides.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In addition, if below in described each embodiment of the utility model involved technical characteristic do not form conflict each other and just can mutually combine.
The utility model embodiment provides a kind of outdoor optical cable lightning protection rack, and for carrying out lightning protection to the optical cable wire harness with metallic strength member, compared with prior art, its difference is, this lightning protection rack comprises:
Equipment compartment;
Be positioned at the lightning protection storehouse bottom equipment compartment; And
Be located in described lightning protection storehouse, with the lightning proof ground of the casing insulation of this lightning protection rack and arrange, described lightning proof ground row has at least one cable fixed part;
The described optical cable wire harness with metallic strength member is divided into metallic strength member and optical cable fibre core at tail end, and described optical cable fibre core stretches into equipment compartment from the perforate at top, lightning protection storehouse, and described metallic strength member is arranged by cable fixed part ground connection.
Particularly, above-mentioned lightning protection rack is specially provided with lightning protection storehouse, carries out ground connection setting, effectively achieve lightning protection to metallic strength member.
embodiment 1:
The utility model example 1 provides a kind of outdoor optical cable lightning protection rack, and for carrying out lightning protection to the optical cable wire harness with metallic strength member, as shown in Figure 1, this rack comprises: equipment compartment 1, fixed bin 2 and lightning protection storehouse 3.
Wherein, equipment compartment 1, fixed bin 2 and lightning protection storehouse 3 set gradually from top to bottom, lightning proof ground row 31 is provided with in lightning protection storehouse 3, the casing insulation of itself and this lightning protection rack, lightning proof ground row 31 has multiple cable fixed part, each cable fixed part is made up of a through wires hole and a wire harness clip gripping members, and the wire harness be arranged in through wires hole is fixed by both in cooperation.The static line row 21 for fixed beam is provided with in fixed bin 2.
The optical cable wire harness with metallic strength member is divided into metallic strength member 41 and optical cable fibre core 42 at tail end, optical cable fibre core 42 stretches into fixed bin 2 from the perforate at top, lightning protection storehouse 3, stretch into equipment compartment 1 again after fixing by static line row 21, metallic strength member 41 is arranged by cable fixed part ground connection.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
