High density polyethylene (HDPE) is placed in injection molding machine and is melted；And it is molded and to form the first cap ontology and be located at right above the first cap ontology
And the second cap ontology being mutually tightly connected with the first cap ontology upper end, make the first cap body interior have first to hold cable hole, first
Cap ontology lower end is opening, the second cap body interior has second to hold cable hole, the second cap ontology upper end seals, first holds cable hole
It is communicated with the second appearance cable hole, makes the outer surface of the second cap ontology that there are multiple annular grooves being parallel to each other；Form cable socket
Seal cap mold blank body；
Step 2: installing cable end seals cap semi-finished product mold, will be put by composite material in another injection molding machine
It is uniformly mixed and melts, and injection molding forms upper end and the first cap on the cable end seals hat cone tool blank body that the first step is formed
Bonding first firmly in ontology upper end lower surface shrinks multiple protrusions of wall body and the inner surface for protruding from the first contraction wall body
Component is formed with aeration tank between the first contraction wall body and the side wall of the first cap ontology；Second fixation member is located in aeration tank,
For the inner surface of first contraction wall body around the first appearance cable hole is formed, second holds the second appearance cable hole of the inner sidewall formation in cable hole
The diameter in the first appearance cable hole that the inner surface that diameter shrinks wall body less than first is formed；The protruding part is that ring logical first is received
The whole circle inner wall distribution of contracting wall body；Aeration tank is externally air-locked；Form cable end seals cap semi-finished product；It is described compound
Material is made of the raw material of following parts by weight: 25~35 parts of polyphenylene oxide resin；15~25 parts of binary nitroso-fluoro-elastomers；It is poly-

Glass fibre of the size no more than 0.03mm: 5~15 parts；2~4 parts of carbon black；
Step 3: the step of installation valve inside: puncturing the cable end seals cap semi-finished product of second step formation, thorn with tool
Tear is located on aeration tank, punctures the first cap ontology upper end face downwards from the first cap ontology upper end face, takes a valve inside, will
Valve inside lower end position in aeration tank enters into aeration tank and mutually fixes with the second fixation member, and the first fixation member is fixed on
Valve inside upper end, and it is located at the first fixation member on the upper surface of the first cap ontology upper end；Keep aeration tank externally airtight；
Complete the production of cable end seals cap.
As simplified structure, in the present invention, can not have protruding part completely；In this case, the aeration tank
Other places other than valve inside are not communicated with surrounding；Ensure that can be inflated valve inside from outside, thus
It squeezes the first contraction wall body and is close to the oversheath of cable socket, reach after pressing, carry out heating appropriate, make cable socket
Seal cap is shunk by heating power and gas pressure is tightly placed on the oversheath of cable socket, ensure that cable or optical cable and outside
Isolation, makes moisture not and can enter cable or cable interior, ensure that the block-water performance of cable, meanwhile, have in cable or optical cable
When center reinforcemen, center reinforcemen is extend into the second appearance cable hole, and cable end seals cap will not be made to damage, therefore for cable
Or the protecting effect that blocks water of optical cable is more excellent；Certainly, when there is protruding part, the optical cable end of wide range of diameters may be implemented
Fixation, i.e., be suitable for from lesser diameter to biggish diameter, and to obtain optical cable end multiple close for multiple protruding parts
Envelope protection can be equally fixed on outside cable socket by the way of inflating additional pyrocondensation.In the present invention, annular groove is deposited
Allowing the second cap ontology to compress or stretch, can usually compressed, since cable or optical cable contraction or expansion cause
When cable or optical cable reinforcer stretch out, stretching out power can be such that the second cap ontology extends, but will not puncture the second cap ontology, reach
The mesh of effective protection optical cable or cable has, and keeps the block-water performance of optical cable or cable more excellent；The present invention is easy to make, and can be used
Integrally formed method manufacture, and structure is simple, practical；In the present invention, aeration tank other than at valve inside, not with external aeration；When
So, valve inside is valve inside commonly used in the prior art, as can be on bicycle, automobile tire etc..
Present invention use in cable end seals, is realized using following methods step: first by optical cable or electric end
End is truncated；Then optical cable or electric end end are extend into the first of cable end seals cap to hold in cable hole, and makes optical cable or electricity
Hold the gap of 10~50mm of distance holding between end and the upper end inner wall of the first cap ontology；Then using air charging system to valve
Core is inflated, and makes the inner surface (when no protruding part) of the first contraction wall body or the outer shield of protruding part and optical cable or cable
Set is mutually close to；Taking heating tool in the first cap body exterior again, circumferentially heating makes the first cap ontology abutting be contracted in optical cable or cable
Surface of outer sheath, be cooled to room temperature, complete the sealing of optical cable or electric end end.
Therefore, the present invention have following main the utility model has the advantages that be simple to manufacture, structure is simple, it is versatile, be used in cable or
When optical cable end seals, block-water effect is excellent, itself is hardly damaged；The present invention is easy to seal optical cable or cable socket.
The present invention is not limited to above-mentioned preferred forms, it should be understood that design of the invention can be by other various shapes
Formula is implemented to use, they also fall in protection scope of the present invention.
