Description
Technical field
The present invention relates to fields of communication technology, and in particular to a kind of cable splice closure.
Background technology
Cable splice closure is by two or more cable connection and the component of protection, is the important device in lightguide cable link
One of material.It is widely used in communication, network system, closed-circuit TV monitoring system etc..Cable splice closure in existing finished product is general
Using plastic manufacturing, such as ABS etc. also has the cable splice closure using material preparations such as makrolon.And optical cable outer layer is general
Using polypropylene material, joint uses metal material, due to these cable components and the coefficient of thermal expansion of cable splice closure
Difference, under different stress or thermal environment, the hot contracting properties of a variety of materials also gap causes different inside and outside connector box
The temperature difference and generate the phenomenon of expansion or shrinkage unevenness, may will produce elastic difference etc. in connector box so as to cause optical cable and ask
Topic.
Therefore, it is necessary to be improved to Hafu-type connector box in the prior art, can overcome because of temperature change
When larger, caused by cable loosen the problem of.
Invention content
The present invention is in view of the deficiencies in the prior art, it is proposed that a kind of novel cable splice closure is particularly suitable for
The cable splice closure made of engineering plastics, has many advantages, such as that pressure-bearing is strong, water resistance is strong.
In order to solve defect existing in the prior art, the technical solution adopted in the present invention is：A kind of cable splice closure,
Include the upper casing and lower casing connected by connector, opposite upper semi-circle is respectively equipped on the longitudinal side wall of the upper casing and lower casing
Hole and lower half circular hole, the upper half circular hole and lower half circular hole form circular optical cable and connect hole, the lateral sidewalls of the upper casing and lower casing
On have the hole being arranged in order, be fixedly installed ventilating pad at the corresponding hole of madial wall of the upper casing and lower casing
Layer, the ventilation bed course from outside to inside respectively light shield layer, waterproof ventilative layer and metal net layer.
Inventor has found by concentrating on studies, and the cataclysm of temperature is one of the main reason for loosening at fiber cable joint,
Therefore, how the influence by temperature shock to cable splice closure is the important topic studied, and by way of increasing and breathing freely, it can
To solve the above problems to greatest extent, it is not limited to theoretical constraint, when environment temperature generates cataclysm, due to cable splice closure
" non-tight state " and generate the circulation of gas and exchange so that the temperature difference inside and outside connector box is not too large, so reduce
The phenomenon of expansion or shrinkage unevenness that generates of the different temperature difference, and avoid optical cable and lead to the problem of loosening in joint.
But with and the problem come is function that cable splice closure after trepanning loses waterproof, therefore, in the present invention
Preferred waterproof ventilative layer is PTFE air-filtering membranes.The PTFE air-filtering membranes utilize the unique chemistry of polytetrafluoroethylene film
The performance of soda acid corrosion resistance and permeable watertight has achieved the purpose that obstruct liquid water or steam.In bed course of ventilating, first
Layer uses light shield layer, main purpose to be that shading and the filtering to granule foreign in air, second layer waterproof ventilative layer are main
For carrying out waterproof and ventilative, the skeleton rigidity of third layer metal net layer bed course primarily to holding is ventilated.
In a preferred embodiment of the present invention, the ventilation bed course by bonding or screw be fixed to the upper casing and
The madial wall of lower casing.Preferably, the ventilation bed course is screwed the madial wall to the upper casing and lower casing.
In a preferred embodiment of the present invention, between the upper casing and the lower casing using fasten, riveting or
It is bolted.Preferably, the upper casing be respectively set fluted on the joint surface of the lower casing, set respectively in the groove
It is equipped with sealing ring.
In a preferred embodiment of the present invention, the optical cable connects the inner circumferential in hole and is provided with rubber spacer.
The beneficial effects of the invention are as follows：
1, cable splice closure of the invention is compared with cable junction box in the prior art, can be with by the way that hole is arranged
Gas exchanges are carried out between environment, can be balanced the temperature difference between outside inside cable junction box, be avoided because of temperature shock
The phenomenon that fiber cable joint that is uneven and generating that expands with heat and contract with cold of the material brought loosens.Further, by being set at hole
Set the ventilating pad of special construction so that it still keeps good water resistance while with excellent venting capability, avoid because
Seepage problem caused by trepanning.
2, cable splice closure of the invention is provided with rubber seal portion between the joint surface that circular optical cable connects hole and upper and lower shell
Part further increases the performance of waterproof.
3, cable splice closure of the invention is simple in structure, and manufacturing cost is low, is suitble to industrialized production and large-scale application.
