The first step：Install cable end seals cap blank mould, and take low density polyethylene (LDPE) or medium density polyethylene or
High density polyethylene (HDPE), it is placed in injection machine and is melted；And it is molded and forms the first cap body and directly over the first cap body
And the second cap body being mutually tightly connected with the first cap body upper end, make the first cap body interior have first to hold cable hole, first
Cap body lower end is opening, the second cap body interior has second to hold cable hole, the second cap body upper end seals, first holds cable hole
Communicated with the second appearance cable hole, make the outer surface of the second cap body there are multiple annular grooves being parallel to each other；Form cable socket
Seal cap mould blank body；
Second step：Cable end seals cap semi-finished product mould is installed, will be put into by composite in another injection machine
It is well mixed and melts, and injection forms upper end and the first cap on the cable end seals hat cone tool blank body that the first step is formed
Multiple projections of bonding the first contraction wall body and the inner surface for protruding from the first contraction wall body firmly in body upper end lower surface
Part, first shrinks between wall body and the side wall of the first cap body formed with aeration tank；Second fixed component 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 madial wall formation in cable hole
Diameter is less than the diameter that first that the first inner surface for shrinking wall body is formed holds cable hole；The protruding part is that ring logical first is received
The whole circle inwall 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 up 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-
15~30 parts of olefin elastomer；5~10 parts of polytetrafluoroethylene (PTFE)；3~5 parts of stearyl ester zinc；Diphosphorous acid pentaerythrite distearyl alcohol
0.3~0.6 part of ester；3~5 parts of Tissuemat E；1~3 part of sulphur；5~10 parts of polyethylene glycol；Aluminium hydroxide：10~20 parts；It is maximum
Size is not more than 0.03mm glass fibre：5~15 parts；2~4 parts of carbon black；
3rd step：The step of installing valve inside：The cable end seals cap semi-finished product of second step formation, thorn are punctured with instrument
Tear is located on aeration tank, punctures the first cap body upper end face downwards from the first cap body upper end face, takes a valve inside, will
Valve inside lower end position in aeration tank enters into aeration tank and mutually fixed with the second fixed component, and the first fixed component is fixed on
Valve inside upper end, and the first fixed component is located on the upper surface of the first cap body upper end；Make aeration tank externally airtight；
Complete the making of cable end seals cap.
As simplified structure, in of the invention, can not have protruding part completely；In this case, the aeration tank
Other places in addition to valve inside are not communicated with surrounding；It ensure that and valve inside can be inflated from outside, so as to
Extrude the first contraction wall body and be close to the oversheath of cable socket, reach after pressing, carry out appropriate heating, 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, moisture is seted to ensure that the block-water performance of cable from entering cable or cable interior, meanwhile, have in cable or optical cable
During center reinforcemen, center reinforcemen is extend into the second appearance cable hole, will not damage cable end seals cap, therefore for cable
Or the protecting effect that blocks water of optical cable is more excellent；Certainly, when there is protruding part, it is possible to achieve the optical cable termination of wide range of diameters
Fixation, i.e., be suitable for from less diameter to larger diameter, and to obtain optical cable termination multiple close for multiple protruding parts
Envelope protection, it can be equally fixed on by the way of the additional pyrocondensation of inflation outside cable socket.In the present invention, annular groove is deposited
So that the second cap body can compress or stretch, and can usually be compressed, because cable or optical cable contraction or expansion cause
When cable or optical cable reinforcer stretch out, stretching out power can extend the second cap body, but will not puncture the second cap body, reach
The mesh of effective protection optical cable or cable has, and makes the block-water performance of optical cable or cable more excellent；The present invention is easy to make, and can use
Integrally formed method manufacture, and it is simple in construction, practical；In the present invention, aeration tank in addition at valve inside, not with external aeration；When
So, valve inside is valve inside commonly used in the prior art, as can be with bicycle, automobile tire etc..
Use of the invention in cable end seals, is realized using following methods step：First by optical cable or electric end
Termination is truncated；Then optical cable or electric end termination are extend into cable end seals cap first is held in cable hole, and makes optical cable or electricity
Hold the gap of 10~50mm of distance holding between termination and the upper end inwall of the first cap body；Then using aerating device to valve
Core is inflated, and makes the inner surface of the first contraction wall body（During without protruding part）Or the outer shield of protruding part and optical cable or cable
Set is mutually close to；Taking heating tool again, circumferentially heating makes the first cap body be close to be contracted in optical cable or cable in the first cap body exterior
Surface of outer sheath, be cooled to room temperature, complete the sealing of optical cable or electric end termination.
Therefore, the present invention has following main beneficial effect：Be simple to manufacture, be simple in construction, be versatile, used in cable or
During 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 will be appreciated that design of the invention can be by other a variety of shapes
Formula is implemented to use, and they are also fallen within protection scope of the present invention.
