Embodiment
The preferred embodiments of the present invention are illustrated below in conjunction with accompanying drawing, it will be appreciated that preferred reality described herein
Apply example to be merely to illustrate and explain the present invention, be not intended to limit the present invention.
For problems of the prior art, by multi-party investigation and engineer testing, according to embodiments of the present invention, such as scheme
There is provided a kind of perfusion of cable bundle flange and encapsulating method shown in 1 and Fig. 2, specific solution is as follows：
(1) by the test of many times irrigated big 703 glue in south, encapsulating method, the height of every layer of perfusion and corresponding are specified
Curing and time.
According to the characteristic of silicon rubber, entered first in perfusion by aperture (the water conservancy diversion frock when aperture refers to encapsulating)
Row gummosis, reduces the infiltration of bubble；Require to be not more than 3mm (including 3mm) per thickness degree during perfusion, enter again after bottom solidification 24h
Row one layer of perfusion above (potting compound can be found in the potting compound 9 in Fig. 1, and bunch of cables can be found in the bunch of cables 8 in Fig. 1)；If filling
Envelope height is 3~5mm, after the normal temperature cure time is 24h, still needs to carry out high temperature drying in high-temperature cabinet, it is desirable to which temperature must not be high
In 40~50 DEG C, the time is 8h optimums.
Ring flange (such as ring flange 7) after perfusion, referring to Fig. 1.As seen from Figure 1, the solidification of ring flange perfusion glue, embedding body
Surface is smooth, bubble-free, without cross flow, silicone rubber seal meets the requirements；After the experiment examination of 100 DEG C of high temperature, embedding body without
Change.
(2) due to the poor sealing of the general bi-component epoxide-resin glue of JC-311, it is impossible to meet design requirement, filled
It is also flexible before note, it is necessary to carry out the encapsulation process of ring flange, it is contemplated that the good airproof performance of big 703 glue in south, with reference to instrument on bullet

10mm, this thickness is 2/3 or so of ring flange base thickness, referring to Fig. 2；Elongated slot and central aperture size are pressed, with big 703 silicon rubber in south
Sealing ring one is made, is filled out in groove；Wire hole in the middle of ring flange is the through hole of a rectangle, and the seal groove milled out is exactly one
Step, be in order to make rubber seal slot milling, that is, in Fig. 1 shade position；
2. embedding is carried out using big 703 silicon rubber in south in sealing area, to being carried out between flange tray bottom and cable after solidification
Layering perfusion solidification, is flushed until with ring flange inner surface；
3. because big 703 silicon rubber in south is nonpolarity structure, the general bi-component epoxide-resin glue of JC-311 used is irrigated
For polar structure, this two kinds of glue amalgamations are bad, therefore use 6mm steel plates to make one piece of cover plate (i.e. cover plate 3), in the middle of cover plate according to
Flange line outlet (i.e. flange wire hole 6) size mills out a threading hole (i.e. cover plate wire hole 2), and cover plate is arranged on homemade squeeze
On pressure seal ring (i.e. silicone rubber O-ring 1), reach that sealing (carries out leak stopping close referring to big 703 silicon rubber in south in crush seal circle
At envelope 5) effect while, big 703 glue in south is kept apart with JC-311 glue, makes this two kinds of glue Nian Jie with metal material；Cover plate
It can be fixedly connected between ring flange using screw (such as screw 4)；
4. to being sealed with wax between the wire and wire outside ring flange wire hole using No. 65 ceresine, it is desirable to which temperature of sealing with wax is
120~130 DEG C.
It is 1kPa to carry out maximum leakage amount in seal tightness test, 10min to the ring flange irrigated, meets design requirement.
The cable bundle flange perfusion of above-described embodiment and encapsulating method, take cable bundle flange to make sealing ring, line by oneself
Between the perfusion of sealing wax, sealing technology method, solve the technical barrier of bunch of cables air-tightness, realize the reliable of body instrument room
Sealing, greatly reducing body instrument room gas leakage causes the risk of instrument, cable failure, improves the flight reliability of guided missile.
