Background technology:
The watertight load that neutral buoyancy optical cable watertight load connector is mainly used in the systems such as underwater towing platform, unmanned remotely controlled submersible vehicle, neutral buoyancy towed body between neutral buoyancy optical cable connects, because these systems all need to guarantee floating any depth location in the seawater, and pulled by neutral buoyancy optical cable and connector, front end sensor measuring and back end signal processing controls need multi-channel optical fibre to transmit, therefore neutral buoyancy optical cable watertight load connector need meet connecting fiber 6 ~ 24 core, and density is at 1.01g/cm
3~ 1.03g/cm
3between, external diameter is no more than φ 35mm, and be suitable for cable outer diameter φ 5mm ~ φ 15mm, tensile strength is not less than 60% requirement such as grade of optical cable breaking load.
At present, prior art has the neutral buoyancy optical cable watertight load connector of two kinds of structures, the neutral buoyancy optical cable watertight load connector of the first structure, as shown in Figure 1, be divided into plug and socket, plug comprises glass microballoon a2, tailstock a3, pad a4, sealing-plug a5, hold out against ring a6, support a7, bonding cover a8, plug body a9, set nut a10, plug baffle plate a11, plug core body a12, optical fiber ceramic lock pin a15, lock pin spring a16 and optical fiber ceramic sleeve pipe a17, socket comprises glass microballoon b2, tailstock b3, pad b4, sealing-plug b5, hold out against ring b6, support b7, bonding cover b8, socket blocking plate b13, jack housing b14, optical fiber ceramic lock pin b15 and lock pin spring b16.Pad a4 in plug, sealing-plug a5, hold out against ring a6, support a7 and bonding cover a8 is all positioned at plug body a9, bonding cover a8 is used for bonding with optical cable c1, bonding cover a8 is connected with support a7, support a7 holds out against with holding out against ring a6, sealing-plug a5 utilizes tailstock a3 and pad a4 to be pressed on and holds out against ring a6 side, tailstock a3 is connected with plug casing a9, tailstock a3, pad a4, sealing-plug a5 and hold out against ring a6 and be locked on optical cable c1 outside surface, plug casing a9 outside surface is bonded with the glass microballoon a2 that counterweight is good, screw is used to connect between plug baffle plate a11 and plug core body a12, optical fiber ceramic lock pin a15 utilizes plug baffle plate a11 and plug core body a12 to be fixed on support a7, lock pin spring a16 withstands between plug baffle plate a11 and optical fiber ceramic lock pin a15.Glass microballoon b2 in socket, tailstock b3, pad b4, sealing-plug b5, to hold out against ring b6, support b7, bonding cover b8, socket blocking plate b13, jack housing b14, the annexation of optical fiber ceramic lock pin b15 and lock pin spring b16 and position relationship the same with plug, in socket, namely jack housing b14 has the effect of shell a9, also possesses the function of plug core body a12 simultaneously, optical fiber ceramic lock pin b15 first utilizes plug baffle plate b13 and is fixed on support b7, then is withstood between socket blocking plate b13 and optical fiber ceramic lock pin b15 by lock pin spring b16.Optical fiber ceramic lock pin a15 in the plug of said structure neutral buoyancy optical cable watertight load connector and the optical fiber ceramic lock pin b15 in socket utilizes the optical fiber ceramic sleeve pipe a17 in plug and set nut a10 to carry out butt coupling, O type circle c18 and sealing-plug a5, b5 is utilized to carry out water-pressure sealed, bonding cover a8, b8 is utilized to carry out bondingly making it can bear certain pulling force to optical cable c1, utilizing glass microballoon a2, b2 to be bonded in connector shell on the surface to reach when greatly increasing displacement of volume, playing the effect reducing connector global density.Bonding glass microballoon be the small hollow glass spheroid of a kind of size, be made up of Inorganic Non-metallic Materials, diameter range is generally at 10 ~ 180 microns, and bulk density is 0.1 ~ 0.25 gram/cc.
The physical construction of the neutral buoyancy optical cable watertight load connector of the second structure is substantially identical with the neutral buoyancy optical cable watertight load connector of the first structure, but the not bonding hollow glass micropearl in its surface, but the global density reducing connector by reducing density of material.The all parts of connector all adopt low density non-metallic materials processing, such as ABS, nylon, teflon etc., the density of such material is well below density metal, and the connector global density therefore processed can meet the neutral buoyancy requirement of density close to seawater.
The thinking of the neutral buoyancy optical cable watertight load connector of the first structure is that connector weight is constant, by adopting the method for bonding hollow glass micropearl, when weight increases few, greatly increase the volume of connector, thus reduce the density of connector, the density of final connector is controlled by the volume controlling bonding hollow glass micropearl.The neutral buoyancy optical cable watertight load connector of the first structure of prior art has following four shortcomings: the increase of (1) bonding volume can only be realized by the increase of length or external diameter, and the significantly increase of length can be unfavorable for the folding and unfolding of optical cable, the increase of external diameter then can increase resistance and noise under water greatly, is unfavorable for underwater towing and detection sensing; (2) because hollow glass micropearl that optical cable is bonding with the afterbody that connector combines can not play the function of water-pressure sealed, when the sealing-plug in connector lost efficacy, will cause the seal failure of connector entirety, sealing reliability significantly reduces; (3) hollow glass micropearl uses bonding agent to be bonded in connector shell and optical cable root outside surface, under long duration of action, may peel off, thus destroy the density performance of connector; (4) technological operation of bonding hollow glass micropearl controls comparatively complicated, is difficult to the density requirement meeting connector accurately.
The thinking of the neutral buoyancy optical connector of the second structure is under the prerequisite of connector shape invariance, uses the nonmetallic materials that density is lower, and connector density is reduced greatly.But the intensity of nonmetallic materials generally will lower than the intensity of metal material, and therefore the physical strength of nonmetal connector is not high, can not be subject to too high pressure, pulling force and shearing force, cannot meet the requirement of underwater towing.Therefore, the neutral buoyancy optical connector of the second structure has following four shortcomings: (1) if connector shell uses the nonmetallic materials of easily processing, then can cause outer cover intensity greatly to reduce, and can not play the effect that protection is inner; (2) processing due to connector shell is comparatively complicated, if use high strength nonmetallic materials, then can greatly improve difficulty of processing and processing cost; (3) the bonding cover of connector uses process for un-metal material, bonding agent adhesive effect can be caused bad, thus greatly reduce optical cable pulling-out force in the connectors; (4) can there is slow catabiosis in nonmetal most of material, also cannot meet the requirement of system Long-Time Service.
Summary of the invention:
