The invention provides a connector and an underwater cable assembly using the connector. The cable assembly comprises a wire and a connector connected onto at least one end of the wire, wherein the tail part of the connector is provided with a connection section. The cable assembly also comprises a sheath sleeving the connection section and in pressing connection with the connection section via the connector; and the outer peripheral surface of the connection section is provided with a groove for enabling the sheath to be submerged when the sheath is radially pressed. Through convex-concave matching between the sheath and the groove, the friction between the sheath and the connection section is increased, falling prevention between the sheath and the connection section is facilitated, and the sealing performance between the sheath and the connection section is also improved.
Description
Technical field
The present invention relates to a kind of connector and use the underwater cable assembly of this connector.
Background technology
Along with the development of electrical engineering, underwater connector obtains as a kind of conductive connecting device and applies more and more widely, and as the conductive connecting device be applied under water, the whether excellent of its sealing property is the key determining underwater electrical connector performance.
The Chinese invention patent that application publication number is CN103618280A, Shen Qing Publication day is 2014.3.5 discloses a kind of filling type insulated enclosure beamline construction that can be widely used in underwater electrical connector, this sealed beam line structure comprises the tail nut and linkage section that are connected to connector shell rear end, the rear end of tail nut is arranged with Sealed casing pipe and sheath, Sealed casing pipe is tightened by steel band and connector and is sealedly connected on tail nut, wire is positioned at Sealed casing pipe, oil-filled insulating oil in Sealed casing pipe, prevents outside moisture from entering.In order to improve the bonding strength between Sealed casing pipe and tail nut, prevent Sealed casing pipe from departing from from tail nut, the rear end of tail nut from front to back external diameter becomes large gradually, like this when steel band and Sealed casing pipe, relative to tail nut, relative displacement occurs backward, because the internal diameter of steel band is constant, what sealing shroud can be restrained by steel band more and more enters, and realizes the anticreep of Sealed casing pipe and tail nut.But smooth engagement between the tail nut outer peripheral face of this sealed beam line structure and the internal face of Sealed casing pipe, when insulating oil in Sealed casing pipe enters between the contact-making surface of Sealed casing pipe and tail nut, just greatly reduce the frictional force between two contact-making surfaces, like this when Sealed casing pipe under tension is larger, Sealed casing pipe is still easy to depart from from tail nut, and it is unreliable to connect.
Summary of the invention
The object of the present invention is to provide a kind of connector, be connected insecure problem in order to solve existing tail nut with Sealed casing pipe; Meanwhile, present invention also offers a kind of underwater cable assembly using this connector.
In order to solve the problems of the technologies described above, connector of the present invention adopts following technical scheme: a kind of connector, comprise the linkage section for being set with for sheath being located at tail portion of connector, the outer peripheral face of described linkage section is provided with at sheath by the groove supplying sheath to submerge during radial compaction.
Described linkage section is isometrical tubular structure.
Described groove is the annular groove coaxially arranged with linkage section.
Described annular groove has multiple and axially spaced-apart to arrange.
Underwater cable assembly of the present invention adopts following technical scheme: a kind of cable-assembly, comprise wire and be connected to the connector of wire at least one end, the afterbody of described connector is provided with linkage section, described cable-assembly also comprises and is enclosed within linkage section and compresses with described linkage section the sheath be connected by connector, the outer peripheral face of described linkage section be provided with sheath by during radial compaction for the groove that sheath submerges.
When described sheath deforms at connected piece radial compaction, crushed element submerges in described groove.
Described linkage section is isometrical tubular structure.
Described groove is the annular groove coaxially arranged with linkage section.
Described connector is that ring is located at sheath periphery and sheath is pressed on the pressure ring of linkage section outer peripheral face.
The two ends of described wire are all connected with connector, and the two ends of described sheath are connected on the linkage section of two connectors, are filled with insulating oil in the inner chamber that sheath and two connectors surround.
The linkage section outer peripheral face of the tail portion of connector of underwater cable assembly of the present invention is provided with groove, when sheath is enclosed within linkage section and connected piece compresses, sheath can submerge in the groove of linkage section outer peripheral face, the frictional force between sheath and linkage section is increased like this by the male-female engagement of sheath and groove, be conducive to the anticreep realizing sheath and linkage section, also improve the sealing between sheath and linkage section simultaneously, not only prevent outside moisture from entering in sheath, and the frictional force avoided the insulating oil in sheath to enter the gap between sheath and linkage section and reduce between sheath and linkage section, substantially increase the bonding strength of sheath and linkage section.
Further, when sheath deforms at connected piece radial compaction, the crushed element of sheath submerges in the groove of linkage section, the tightness degree of the Contact of sheath and linkage section is ensure that like this by the strain of sheath, improve sealing effectiveness, increase the frictional force between sheath and linkage section.
Further, linkage section is isometrical tubular structure, like this when sheath is enclosed within linkage section, easy for installation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment one of underwater cable assembly of the present invention;
Fig. 2 is the schematic enlarged-scale view at A place in Fig. 1.
Embodiment
The embodiment one of underwater cable assembly of the present invention: as shown in Figure 1-2, comprise wire 4 and the connector 1 being connected to wire 4 two ends, wire 4 and connector 1 are welded to connect.Underwater cable assembly also comprises for being wrapped in by wire 4 interior with the sheath 2 itself and water segregation sealed, and the two ends of sheath 2 are tightly connected with the connector 1 at wire 4 two ends respectively.
Connector 1 side opposing with wire 4 is front end inserted terminal, and the rear end of connector 1 is provided with the linkage section 10 for connecting sheath 2.Linkage section 10 is axially isometrical tubular structure, and its endoporus is used for for wire 4 passes from back to front and is connected with connector 1, and sheath 2 is enclosed within the outside of linkage section 10 and is pressed on by pressure ring 3 on the outer peripheral face of linkage section 10.
In the present embodiment, on the outer peripheral face of linkage section 10, axially spaced-apart is provided with multiple annular groove 100, annular groove 100 and linkage section 10 are coaxially arranged, diameter is constant in the axial direction for the internal face of sheath 2, sheath 2 to be enclosed within linkage section 10 and by pressure ring 3 radial compaction time, sheath 2 is that radial strain occurs, and the part of strain is submerged in annular groove 100.Like this by the male-female engagement of the annular groove 100 on the elastic part of sheath 2 and linkage section 10, the anticreep between sheath 2 and linkage section 10 effectively can be realized.Simultaneously, because radial strain occurs sheath 2, so between sheath 2 and linkage section 10, there is larger clamping force, this part clamping force not only substantially increases the frictional force between sheath 2 and linkage section 10, sheath 2 is not easily departed from from linkage section 10, and also improves the sealing effectiveness between sheath 2 and linkage section 10.
