Hermetic seal and the water-stop of radio frequency co-axial cable subassembly comprise paired connector be connected between sealing and the sealing of junction between connector and cable, wherein between connector, adopt of sealing seals at matching connector inserting position more, easy realization, and the sealing more complicated between connector and cable, it is important that hermetically-sealed construction and measure seem especially, and existing water-stop and air-tight structure and measure are realized by fluid sealant and injection moulding sebific duct usually.
Sealant sealing structure as shown in Figure 1, filling with sealant in the gap 4 that outer conductor 1 and outer conductor 2 are formed, the outer conductor 3 contacted with cable 6 oversheath designs seal groove 3, filling with sealant in seal groove 3, after adhesive curing to be sealed, again at outer conductor 1, the coated heat-shrink tube 5 of pyrocondensation outside outer conductor 2 and cable 6 oversheath, realize the sealing between cable and connector, in this encapsulating method, fluid sealant is fluid, affect greatly by artifact during encapsulating, fluid sealant loading is inconsistent, poor stability, glue affects larger by temperature factor simultaneously, curing time is long, working (machining) efficiency is low, after colloid solidification, cable assembly is when alternating bending, fluid sealant can not be fitted with the case of bending of cable, between there is gap, seal failure, equipment is caused normally to work or to damage.
Mould-injection tube seal structure as shown in Figure 2, directly carries out fitting tightly injection moulding sebific duct 7 thus realizing sealing purpose at cable 3 crust and connector outer conductor 1.This sebific duct processing cost is high, and kind is many.When cable bend, produce gap between sebific duct and cable, seal failure, cable can produce distortion simultaneously, and affect electric property, poor stability, this kind of encapsulating method is generally used for harder cable assembly.
Utility model content
The utility model provides a kind of hermetically-sealed construction of radio frequency co-axial cable subassembly, to solve the poor sealing that prior art exists, complicated operation, and the problem of cost height and consistency difference.
The utility model device solves the technical scheme that its technical problem adopts:
A kind of hermetically-sealed construction of radio frequency co-axial cable subassembly, comprise connector, welding body, tailstock, cable, sealing ring, seal and heat-shrink tube, connector front end internal cavity arranges outside groove, welding body is step column, two ends arrange open lumen, left end cylindrical dimensional is greater than right-hand member cylindrical dimensional, the welding inner chamber body of body is welded with the screen of cable and is fitted, welding body end face and connector front end inner chamber body end joined, tailstock two ends arrange open lumen, the left end inner chamber of tailstock with weld column right side, body front end and engage, the cavity right side of tailstock and sealing ring are fitted, seal is annular tubular, closely be coated on tailstock profile rear end and cable sheath, heat-shrink tube is annular tubular, closely be coated on connector front end right-hand member, on tailstock and cable sheath.
Above-mentioned sealing ring is two, and be respectively tailstock inner chamber left side and the sealing ring welding in the middle part of the sealing ring and tailstock outer surface that arrange between body right side and between the groove that connector front end inner chamber is outside, these two sealing rings are O type ring-type, silicon rubber material.
The beneficial effects of the utility model are: by the multi-sealed measure to connector inside and connector and cable connecting part position, well achieve water-stop and hermetic seal, sealing reliability is high; Sealing ring, seal material selection silicon rubber, good springiness, when cable assembly bends, silicon rubber can keep fitting with cable sheath and connector, does not cause gap; Silicon rubber is inertia, high-low temperature resistant stability, and weatherability is strong, can be applicable to most cable assembly; Cable assembly assembling is simple, and easy to operate, the used time is short, and efficiency is high; Sealing ring and seal are standard component, and processing is simple, and specification is many, and cost is low.
