Description
Technical field
The invention belongs to underwater sound equipment technical field, and in particular to a kind of longitudinal water of cable and underwater sound equipment connection structure
Decryption method.
Background technology
Underwater sound equipment in water long-term work when cable and the connection structure of underwater sound equipment face the danger of infiltration, once it is electric
The connection structure of cable and equipment is damaged, and water will be entered in the underwater sound equipment being connected with cable by connection structure, and equipment is made
Into irreversible infringement.The direction waterproof of cable can ensure when locally breakage occurs for cable, water will not be by cable inside
Penetrate into underwater sound equipment, it is only necessary to local route repair is carried out to it, the damage without causing equipment.
Direction waterproof is ensured by the dual-seal between insulator and housing and between insulator and contact.Insulation
Sealing between body and housing can be sealed by O-ring, irrigate the various ways such as sealing to realize.And insulator and contact
Between sealing be a critical technological point, and realize the key of direction waterproof.
The direction waterproof method of current watertight connection structure mainly has glass sintering, inlays compression seal and irrigates sealing
The methods of.Glass sintering method is that the glass for making molten condition by high temperature molten glass infiltrates metal surface, glass and metal
Oxide layer occurs chemical bond and reaches the effect of sealing.The encapsulating method is in infiltration hermetically sealed connector and hermetic seal connector neck
There is substantial amounts of application in domain.But glass sintering method has the species of metal material more harsh requirement, only certain several gold
Belong to and realize sealing-in between material energy and glass；Glass sintering complex process, operation difficulty are big；Above all glass sintering is completed
After can not dismantle, cause great obstacle for the later period maintenance of equipment.
It is by by the contact of cable and insulator compression molding, with the mode for inlaying plastic compression to inlay compression seal method
Insulating materials and contact are combined together.The advantages of this method be contact and insulator can be combined into one it is whole
Body, sealing performance are preferable.Defect is that contact and insulator will select the material of expansion coefficient similar, limits optional material
Scope.At the same time in order to ensure the quality of contact and insulating materials combination, it is necessary to carry out corresponding pre-treatment to contact, when
The heavy workload when quantity of contact is more.
Perfusion encapsulating method is between being filled up completely between contact, insulating part and housing by the mobility of perfusion materia
Gap, reaches the effect of sealing after curing.The defects of this method, is non-dismountable, and maintenanceability is poor.
