Cable and connector.At present, existing high pressure crosses sealing of the hole connector to Exterior cable typically bearing, high-voltage shielding line crust
Sealing-plug, plastics retainer plate composition, the sealing that high pressure is crossed between hole connector and connector casing use the knot of radial seal plug
Structure, the shielding that high pressure crosses hole connector is made up of metallic shield ring, metallic shield circle and elastic opening packing ring, metallic shield ring elder generation
Shielding line with high-tension cable is crimped together, then is crimped together with metallic shield circle, because it cannot be guaranteed that metallic shield circle with
Connector casing is fully contacted, and is adjusted contacting using elastic opening packing ring between metallic shield circle and connector casing,
Coupling box body wall thickness must reach more than 15mm.Current high pressure crosses hole connector and there is complex structure, many high costs of component,
Complex procedures production efficiency bottom, easily high-voltage shielding line endothelium is crushed during crimping metallic shield circle, causes the insulation of high-voltage line to drop
It is low, produce electric leakage.Wall thickness to connector casing is required, it is impossible to using in the position of coupling box body wall thickness.
The content of the invention
The purpose of this utility model and provides a kind of simple structure, peace aiming at the above-mentioned weak point of prior art
The dress reliable high pressure of easy to operate, closed shield convenient, with low cost, simple for assembly process crosses hole connector.
The technical solution of the utility model is：Including tubular hold-down support, the hold-down support inner chamber is step cylinder
Shape, including big hole portion, middle hole portion, the small hole portion being sequentially connected；The screen at hold-down support aperture size end is enclosed within for compressing returning
Cover the small retainer plate of head plastics of net；High-voltage shielding line crust sealing-plug, the high-voltage shielding line crust sealing-plug is loaded on macropore
Portion；The big retainer plate of afterbody plastics for fixing high-voltage shielding line crust sealing-plug, the big retainer plate of afterbody plastics is loaded on solid
Determine the big hole portion tail end of bearing.High-voltage shielding line by inner core, gauze screen, screen layer crust, be arranged at inner core and screen layer crust
Between rubber composition, peel off screen layer crust after gauze screen returning be enclosed within hold-down support aperture size end, it is small with head plastics
Retainer plate is compressed.
The big retainer plate of afterbody plastics is step tubular structure, including the small cylinder portion that big cylinder portion and big cylinder portion are connected,
Big cylinder portion outer wall is provided with elastic card claw, and the big hole portion outer wall of tubular hold-down support is provided with the projection for coordinating assembling with elastic card claw；
The small retainer plate of head plastics is identical with the structure of the big retainer plate of afterbody plastics.
The tubular hold-down support outer wall is provided with a circle fixed disk, and fixed side surface is provided with O-ring groove, O-ring ditch
Groove is built with O-ring.
The high-voltage shielding line crust sealing-plug outer wall is provided with zigzag projection, and big hole portion inwall is provided with and high-voltage shielding line
The groove that crust sealing-plug zigzag projection is engaged.
The utility model combines fixed close by hold-down support, high-voltage shielding line crust sealing-plug, afterbody plastics retainer plate
Envelope is sealed to Exterior cable.Sealing between the utility model and connector casing carries out axial static seal using O-ring.This reality
The shielding for crossing hole connector with novel high-pressure uses the plastic shielded retainer plate of head（The also referred to as small retainer plate of head plastics）, make cable
Screen layer tightly embrace hold-down support and form shielding.Hold-down support uses bolt presses to connector casing, casing
Wall thickness is in more than 7mm.
Brief description of the drawings
Fig. 1 is combination schematic perspective view of the present utility model.
Fig. 2 is longitudinal schematic cross-sectional view of the present utility model.
Specific embodiment
In Fig. 1,2, the high-voltage shielding line crust big retainer plate 1 of sealing-plug 2, afterbody plastics is loaded in the afterbody of hold-down support 3,
The head of hold-down support 3 loads O-ring 4, the small retainer plate 5 of head plastics, and high-voltage shielding line crust sealing-plug 2 loads hold-down support tail
Portion inner chamber, is fixed using the big retainer plate 1 of afterbody plastics, and the head of hold-down support 3 is connected with high-tension shielding cable shield, uses head
Plastics small retainer plate 5 in portion's is fixed, and is sealed using O-ring 4 between hold-down support 3 and connector external box of microvave.The afterbody of hold-down support 3
Outside dimension is consistent with the big internal diameter size of retainer plate 1 of afterbody plastics, and the tail section exterior of hold-down support 3 is provided with projection.Hold-down support 3
