Description

A kind of hard-packed cable based on cruciform skeleton

Technical field

The utility model relates to field of cable technology, specially a kind of hard-packed cable based on cruciform skeleton.

Background technique

In order to avoid thunder point attacks the damage to cable directly, drain wire will be installed in cable.Drain wire can in cable Broken by lightning degree is reduced, and reduces the lightning current for flowing into cable, and lightning stroke fuel factor and machinery on cable can be mitigated The energy that effect generates.According to the requirement of production, the specification of drain wire is not identical.

In production, drain wire is normally between twisted pair and sheath, in some cables using cruciform skeleton, When not only containing cruciform skeleton and drain wire in cable structure, but also containing other shielded layers or band, cable after forming Diameter is excessive, and consumptive material is big in production for excessively thick cable, and installation footprint also increases.

Utility model content

The purpose of this utility model is to provide for a kind of hard-packed cable based on cruciform skeleton, so that cable Internal structure is more compact, saves the waste of the clad in production on the outside of twisted pair, while can save the installation of cable Space.

In order to achieve the above-mentioned object of the invention, the utility model uses following technical scheme: one kind being based on cruciform skeleton Hard-packed cable including cruciform skeleton, twisted pair and the sheath for being set in outer layer further include drain wire, described ten Glyph skeleton is equipped with through-hole, and the drain wire is located inside through-hole.

Compared with prior art, using the hard-packed cable with cruciform skeleton of above-mentioned technical proposal, tool Some has the beneficial effect that

1, using the hard-packed cable based on cruciform skeleton of the utility model, so that cable inner structure is more It is compact, reduce the form diameter of forming cable.

2, the stranding diameter in the utility model reduces, and the material loss amount of the clad of be coated on outer layer also synchronizes phase It should reduce, save production cost.

3, after stranding diameter becomes smaller, the installation space of cable can be reduced, be easily installed and construct.

Preferably, the cruciform skeleton is equipped with the opening for entering through-hole for drain wire, the opening and through-hole phase Connection.

Preferably, the one side wall of the opening is outwardly protruding, another side wall of opening and recess from protrusion to adaptation, it is described The channel for entering through-hole for drain wire is formed between opening two sidewalls, the channel is distance identical bending channel everywhere.

Preferably, the side wall of the opening is outwardly protruding, is formed to enter for drain wire between the opening two sidewalls and be led to The channel in hole, the intermediate distance in the channel are less than the distance at both ends.

Preferably, the through-hole is located at the middle part of cruciform skeleton, and the opening is located at the corner of cruciform skeleton.

Preferably, the cruciform skeleton will be divided into four positioning areas inside sheath, and twisted pair is equipped with multipair, Yi Duishuan Twisted wire is located in corresponding positioning area.

It preferably, further include filling line, when twisted pair quantity is less than positioning area quantity, filling line is located at vacant positioning In area.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of hard-packed cable embodiments of the utility model based on cruciform skeleton；

Fig. 2 (a)-(b) is the enlarged drawing in Fig. 1 at A.

Appended drawing reference: 1, cruciform skeleton；11, through-hole；12, it is open；2, twisted pair；3, sheath；31, positioning area；4, it arranges Streamline；5, filling line.

Specific embodiment

The utility model is described further with reference to the accompanying drawing.

It is as shown in Figure 1 the sectional view of the hard-packed cable based on cruciform skeleton, the sheath 3 on the outside of cable will be whole In a cable is coated on.It include cruciform skeleton 1 in cable, the space in sheath 3 is divided into four to determine by cruciform skeleton 1 Position area 31, is equipped with a pair of of twisted pair 2 in a positioning area 31.As shown in fig. 1, have in four positioning areas 31 in sheath 3 Three positioning areas 31 are equipped with twisted pair 2, and in order to keep cable structure, a filling line is equipped in another vacant positioning area 31 5。

In order to enable cable inner structure is more compact, one is equipped with for accommodating drainage at the middle part of cruciform skeleton 1 The through-hole 11 of line 4, such drain wire 4 are located among cruciform skeleton 1, are not take up other spaces outside cruciform skeleton 1.Ten The corner of glyph skeleton 1 is equipped with the opening 12 for entering through-hole 11 for drain wire 4.(a) and (b) is two kinds of openings in Fig. 2 12 structures.The one side wall of Fig. 2 (a) split shed 12 is outwardly protruding, be open 12 another side wall and recess from protrusion to adaptation, opening The channel for entering through-hole 11 for drain wire 4 is formed between 12 two sidewalls, channel is distance identical bending channel everywhere.Fig. 2 (b) The side wall of split shed 12 is outwardly protruding, and the opening forms the channel for entering through-hole 11 for drain wire 4, institute between 12 two sidewalls The intermediate distance for stating channel is less than the distance at both ends.In the present embodiment, it is selected according to the specification of the diameter of through-hole 11 and drain wire 4 With different 12 structures of opening, when the diameter of drain wire 4 and the diameter of through-hole 11 have big difference, opening 12 is using in Fig. 2 (a) Structure, the channel that opening 12 is formed are spacing identical channel everywhere, and the drain wire 4 in through-hole 11 is difficult from opening 12 Abjection, guarantees the stable structure of cable inner；When the diameter of drain wire 4 is suitable with the diameter of through-hole 11, using in Fig. 2 (b) Structure, the spacing at the channel both ends that opening 12 is formed is greater than intermediate spacing, so that drain wire 4 is in into and out through-hole 11 When can more easily, the structure of cruciform skeleton 1 itself will not be destroyed.The drain wire 4 of different size should cooperate in production Different 12 structures of opening.

The above makes preferred embodiments of the present invention, does not depart from for those of ordinary skill in the art Under the premise of the utility model principle, several variations and modifications can also be made, these also should be regarded as the protection of the utility model Range.
