Description
Technical field
The present invention relates to armored cable interconnection technique fields, and in particular to a kind of connector for armored cable.
Background technique
In nuclear radiation detection field, armored cable is widely used, and armored cable connector is also essential, convention connectors
It is made of plug body, tail folder, plug snap ring, plug insulator, plug insertion pin etc., though structure is simple, sealing performance one
As, and the running environment of many detectors is all relatively more severe at present, temperature, humidity variation are bigger, especially under accident conditions
The very strong high temperature that holds is needed to hold high pressure ability.Convention connectors have been unable to meet use demand, have the disadvantage in that and 1) work as spiral shell
When line screws, gasket will receive shearing force, so that seal break-off；2) swivel nut retaining ring is limited by connector construction, is non-closed
Structure is filled in swivel nut by squeezing, and circumferential direction deformation is uneven when stress, leads to cushion unbalance stress, destroys sealing, separately
Outside, often there is the case where being directly ejected swivel nut in retaining ring；3) after the completion of convention connectors sealing, by high/low temperature alternation and anti-
When shake impact, poor sealing performance；4) convention connectors tail folder only leans on welded seal, and after welding surface destruction, sealing cannot be protected
Card；5) contact pin is easy to retreat, and leads to poor contact；6) there are the air gaps between contact pin and shell, are easy sparking.
Summary of the invention
The object of the invention is to place in order to overcome the above-mentioned deficiencies of the prior art, provide a kind of for armored cable
Connector makes up convention connectors defect, improves the practicability of connector.
The technical solution used to solve the technical problems of the present invention is that: a kind of connector for armored cable, including card
Cover component, armouring adapter, armouring tail folder, plug body, insulator snap ring, plug insulator, plug insertion pin, armored cable tail
Portion sequentially passes through ferrule assemblies, armouring adapter, armouring tail folder, and armouring tail folder is fastened with armored cable welding, armored cable tail
The contact pin in portion is docked with plug insertion pin, and armouring tail folder is connect with plug body, and it is exhausted that plug is equipped between plug body and plug insertion pin
Edge, plug insulator are fixed on plug body by insulator snap ring.In order to avoid in connector seal washer because by
Circumferential shearing force causes sealing surface twisting to mill and destroy sealing, the armouring adapter and armouring tail press from both sides between, armouring
It is all made of swivel nut sealed connection between tail folder and plug body, is equipped with swivel nut retaining ring in swivel nut.It is solid with positioning tool in sealing
The mechanical parts for determining swivel nut two sides tighten swivel nut with torque spanner.
Further, connector is attached by plug body and external equipment, when connector plug does not come into operation
When, protection is sealed using plug.It is tightly connected between plug body and plug using swivel nut, swivel nut is equipped in swivel nut and is kept off
Circle.
In the above-mentioned technical solutions, the swivel nut retaining ring is closed loop configuration, is dish in non-stress, outside swivel nut retaining ring
Edge and swivel nut retaining ring inward flange are smooth structure, and tow sides have circumferential ripple among swivel nut retaining ring.Retaining ring is gradually driven plain
When, it is possible to provide very big restoring force, circumferential ripple come into contact with metal covering is squeezed, and increase confficient of static friction.Outside swivel nut retaining ring
Edge towards swivel nut place, swivel nut retaining ring inward flange towards connector shell (i.e. armouring adapter, armouring tail folder, plug body
The shell being in turn connected into) on positive stop lug boss, the internal diameter of positive stop lug boss of the swivel nut retaining ring internal diameter on connector shell with
Between outer diameter, swivel nut retaining ring outer diameter guarantees that swivel nut retaining ring will not influence company between swivel nut minimum diameter and swivel nut root diameter
The assembly of device is connect, and will not be ejected by screw thread pair axial force.Swivel nut retaining ring when screw thread pair screws locking, pressed by swivel nut retaining ring
It is flat and generate very big restoring force, therefore, even if in temperature and humidity acute variation, the inconsistent gasket of thermal expansion coefficient with it is close
Metal is sealed always by very big extruding force, thus intact sealing.It is very big that the restoring force that swivel nut retaining ring generates can give screw thread pair
Axial normal pressure, and circumferential direction ripple and squeeze the confficient of static friction that increases of metal face contact when swivel nut retaining ring flattens, the two
Collective effect allows connector to have shock-proof check.
In the above-mentioned technical solutions, the plug insulator is by forming on plug insulator and under plug insulator, plug
On insulator and plug insertion pin is wrapped up under plug insulator, by under insulator snap ring locking-type plug insulator, the plug
Contact pin periphery is equipped with a circle restriction protrusion, under close-fitting state, on plug insulator, under plug insulator engaging portion formed a circle with
The corresponding limiting groove of restriction protrusion on plug insertion pin, so that plug insertion pin can not be moved forward and backward；Plug insertion pin tail portion uses
Plug-in structure can be docked with armored cable contact pin, realize fast insert-pull form, convenient for safeguarding.Under plug insulator
Insulated part extend to envelope armored cable contact pin, make have insulation between armored cable contact pin and plug insertion pin and plug body
Body barrier, rather than air insulation is depended merely on, junction uses labyrinth circuitous configuration on insulator and under insulator, increases shell
The electric property of connector is effectively guaranteed in insulation distance between contact pin.
In the above-mentioned technical solutions, the plug body is split type structure, can facilitate the swivel nut gear of installation closed loop configuration
Circle, plug body are welded by the big end housing of plug and the small end housing of plug.
In the above-mentioned technical solutions, armouring adapter is increased in armouring tail folder tail portion to protect armouring tail folder and armouring electricity
The pad of cable avoids tail folder from locating to be damaged by corrosion in harsh environment for a long time with armored cable welding surface, armouring adapter one
End is sealed using screw bushing structure and armouring tail folder, and the other end is sealed using ferrule assemblies with armored cable, the design
Energy locking cable does not allow cable self weight tractive force to involve welding surface, welding surface, while the sealing at the structure both ends is effectively protected
Structure has very strong bearing capacity, and connector tail folder portion point is made to have double sealing effect.
The present invention is used for the connector of armored cable, can sufficiently make up the various defects of convention connectors, improves connection
The practicability and reliability of device.
