It will appear the phenomenon that armouring wire pulls failure to deep-sea umbilical cables.
Summary of the invention
In view of the above-mentioned problems, can be applied to deep-sea the object of the present invention is to provide one kind and umbilical cables armouring can be prevented
Steel wire pulls the umbilical cables U-shaped terminal fitting of failure.
To achieve the above object, the present invention takes following technical scheme: a kind of umbilical cables U-shaped terminal fitting, feature exist
In, including fitting sleeve and pressing sleeve, wherein the fitting sleeve is formed by fixedly connecting by connector inner sleeve, connector housing and cover board
Tubular structure；The fitting sleeve uses the stair-stepping tubular structure of second order, institute for plugging fixed umbilical cables, the connector inner sleeve
The upper inside wall for stating connector housing offers annular groove, and it is recessed that the first ladder of the connector inner sleeve is fixedly connected with the annular
Slot, the second ladder and the annular groove of the connector inner sleeve constitute the accommodating space for placing the pressing sleeve, the pressure
The inner wall of set and the second ladder of the connector inner sleeve, which respectively correspond, is provided with several U-shaped protrusions and U-shaped groove, constitutes for solid
Determine the channel of umbilical cables armouring wire.
Further, the junction of the connector housing and the cover board is additionally provided with sealing ring.
Further, the connector housing offers the barrel-like structure of through-hole using top opening and bottom centre, described to connect
The diameter of head housing lower inner wall gradually tapers up.
Further, the cover board uses cyclic structure.
Further, the connector inner sleeve and the connector housing, the connector housing and the cover board and the pressing sleeve
Bolt is all made of between the connector inner sleeve to be fixedly connected.
The invention adopts the above technical scheme, which has the following advantages: in the present invention in the inner wall and connector of pressing sleeve
Second ladder of set, which respectively corresponds, is provided with several U-shapeds protrusion and U-shaped groove, the U-shaped protrusion and U-shaped groove at pressing sleeve inner wall with
U-shaped protrusion and U-shaped groove at second ladder of connector inner sleeve match, and constitute the channel for being capable of fixing armouring wire, U-shaped
Protrusion and U-shaped groove construction so that armouring wire insertion channel after in will not be drawn out easily, by bolt by pressing sleeve with connect
Head inner sleeve is fixed, and puts on outside connector and offers annular groove, secondary fixation can be carried out to pressing sleeve, to protect umbilical cables
Armouring wire at U-shaped terminal fitting is not pulled failure, and structure is simple, and easy for installation and reliable operation can be widely applied
In umbilical cables U-shaped terminal fitting.
