Description
Technical field
The utility model relates to a kind of for installing the sealed part of bunch of cables in fuel tank, especially fuel tanker,
Bunch of cables can be sealingly fixed on the fuel tank floor of aircraft by it.
Background technique
The bunch of cables of more tanlc-aircrafts is when passing through fuel tank sealing floor, due to the gap between the cable in bunch of cables,
There can be the problem of cannot being fully sealed, leading to leakage in fuel tank.Currently, mainly using four kinds of modes in order to avoid above-mentioned interior leakage:
First, casing is arranged in bunch of cables overall length, it is sealed by casing.The program installs and uses inconvenience, and deposits
Complicated problem is replaced after casing damage.
Second, realizing sealing by using electric connector at floor in bunch of cables by electric connector itself, needing passing through
Bunch of cables is disconnected when sealing floor, and the electric connector cooperation on the installation of the both ends of disconnection electric connector, with floor.The party
The major defect of case is, is easy to produce spark, and there are security risks；Electric connector poor reliability；And it is expensive.
Third, bunch of cables is made to pass through prefabricated rubber hole, this is to realize to seal by the cooperation in electric wire and rubber hole, is needed
By every cable all separately through a rubber hole.The program installs and uses inconvenience, and leakproofness is poor.
Fourth, the program passes through glue filling opening to bunch of cables and part through walls in bunch of cables by using part through walls at floor
Encapsulating between inner wall, encapsulating process is complex, and sealant easily flows out cavity, is not easy firm holding, influences leakproofness.?
At present in aircraft in this way, there is leakage in serious in multi rack, leads to that fuel tanker can not be added to full oil condition, aircraft adds
Volume read-out limitation need to be carried out when oily to each fuel tank, the alarm of left and right fuel tank un-balance oil amount, the sliding race of each aircraft may be triggered
A series of problems, such as with being needed before flight to each fuel tank progress Fuel Check.
In view of the above problems, aircraft electrical can be made according to sealed part a kind of known to 10241811 A of document CN
Harness passes through airtight bulkhead and bonding, but larger according to the inner cavity of the sealed part of the prior art, is equipped with and fills
Glue hole, plastic hole and it is not set so that glue is maintained at intracavitary structure, and can not easily judge whether encapsulating is completed, only exist
Sealant could stop pouring into sealant when flowing out from plastic hole, and this time difference easily causes glue to be lost in encapsulating, together
When will affect leakproofness.
Utility model content
Be directed to the problems of in the prior art, the purpose of this utility model is that, propose it is a kind of for fuel tank,
Bunch of cables, can be sealingly fixed to the fuel tank rib of aircraft by the sealed part of installation bunch of cables especially in fuel tanker
On plate.The sealed part can make the bunch of cables convenience of aircraft, sealingly extend through the fuel tank floor of aircraft, corresponding in application
Installation method in the case where, can conveniently, effectively realize bunch of cables inside and the encapsulating between bunch of cables and part through walls.
For this purpose, sealed part according to the present utility model includes by two semicircular part case half pairing shapes through walls
At, columnar part ontology through walls, wherein have cavity in the part case half internal structure through walls, the cavity is at two
In the part body interior formation encapsulating chamber through walls and in the outer circle of the part ontology through walls when part case half pairing through walls
Flange and annular fixing groove are configured on week, wherein being respectively provided at the axial ends portion of the part ontology through walls prevents
The encapsulating baffle of sealant outflow, and the encapsulating baffle is being installed and can be from the part through walls after sealing glue solidifying
It is removed on ontology.It is capable of forming closed encapsulating chamber by the pairing and the encapsulating baffle of part case half through walls, thus
Glue filling opening and plastic hole are eliminated, structure is simplified and can prevent the sealant in encapsulating from flowing out from part through walls, simultaneously
Improve the leakproofness of encapsulating chamber after encapsulating.
Furthermore according to the utility model, each encapsulating baffle includes two semicircular encapsulating baffle half portions, the encapsulating
Baffle half portion is separately positioned at the axial ends portion of the part case half through walls, in two part case half pairings through walls
When, two encapsulating baffle half portions are correspondingly combined to form the encapsulating baffle.This split type construction of the encapsulating baffle
The first encapsulating that can be realized sealed part according to the present utility model, the mounting means installed again, so as to effectively keep away
Exempt from sealant to flow out and improve leakproofness.
Preferably, the encapsulating baffle can be made of the material of soft materials, and the encapsulating baffle is pasted onto institute
At the both ends for stating part ontology through walls.Therefore, the encapsulating baffle can closely surround bunch of cables by plastic deformation, thus
It realizes sealing effect, prevents sealant from flowing out.
According to the utility model, location hole and positioning are respectively equipped on the contact surface of described two part case halfs through walls
Pin, to make two part case half pairing positioning through walls.Preferably, on the contact surface of described two part case halfs through walls
It is respectively equipped with two location holes and two positioning pins.
According to the utility model, the annular fixing groove utilizes institute for installing circlip and retaining ring, the sealed part
It states flange to stick on the fuel tank floor of aircraft and be fixed on the fuel tank floor by the circlip and retaining ring, realize most
Whole installation positioning.Therefore the sealed part ensures that bunch of cables passes through the sealing installation of fuel tanker floor
The basic functional principle of the utility model is as follows: inside the harness for first passing through the position at fuel tank floor to bunch of cables
Encapsulating processing is carried out, after adhesive curing to be sealed, bunch of cables is made to pass through the fuel tank floor of aircraft, completes preliminary arrangement；Later, two
Sealant is filled in the cavity of a part case half through walls respectively and is utilized respectively encapsulating baffle half portion at both ends and blocks sealing
Glue；Next so that two part case halfs through walls is combined to form part ontology through walls and include bunch of cables, on part ontology through walls
Positioning pin and location hole by cooperation carry out pairing positioning, at the same time, encapsulating baffle half portion is correspondingly combined to form encapsulating
Baffle and closely surround bunch of cables；The sealed part formed after pairing is set to pass through the mounting hole on fuel tank floor, it is described
Sealed part is sticked on fuel tank floor and using retaining ring and circlip using its flange is fixed on the sealed part
On fuel tank floor；Finally, the sealant in part through walls to be sealed takes encapsulating baffle off again after being fully cured.
Compared with prior art, the sealed part of the utility model is other than having the advantages that the prior art, moreover it is possible to
It is enough it is more efficient, facilitate filling sealant, prevent sealant from flowing out and guarantee the leakproofness between part and cable through walls.
