Rong Shi: a kind of transducing signal transmission line cable end sealing rotational structure, composition include line end closing collet, interior coupling sleeve and connection
Rotation ring is connect, the line end closing collet is the line end big envelope for transmitting cable, and the cut cable of interior coupling sleeve passes through connection rotation ring bottom
Annulate shaft hole and line end close collet, are closely plugged in the armouring sheath of transmission cable, and interior coupling sleeve outer end is in connection rotation ring
Rotatable, the core for transmitting cable is drawn by interior coupling sleeve pore, and connection rotation ring position opposite with line end closing collet, which is equipped with, to be limited
Opposite swing angle limited section of the swing angle less than 360 °.
The preferred embodiment of above-mentioned technical proposal, the swing angle limited section be line end close collet with couple revolve ring opposite end
Face cotter way is slidably matched mechanism, and the outer end face that line end closes collet is equipped with annular groove, and the sliding pin on the base ring outer end of connection rotation ring is sliding
Dynamic cooperation is placed in annular groove, annular groove cell wall at least one at for indentation annular groove and the recessed seam allowance that is formed.
The preferred embodiment of above-mentioned technical proposal, the swing angle limited section be line end close collet with couple revolve ring opposite end
Face cotter way is slidably matched mechanism, and the outer end face that line end closes collet 1 is equipped with annular groove, at least one in annular groove at be equipped with one and block, connection
The sliding pin connect on the base ring outer end of rotation ring is slidably matched and is placed in annular groove.
The utility model additionally provides that a kind of sensor union end, at least one end has the sensing in connector union end
The sensing cable of signal transmission line cable end sealing rotational structure.
Transducing signal transmission line cable end sealing rotational structure disclosed by the utility model and its sensing cable technique scheme,
It couples connection of the rotation ring for external sensor or connector, and transmission line cable end is sealed by interior coupling sleeve and line end closing collet
It closes, seals rotatable engagement between connection rotation ring and interior coupling sleeve, and rotation angle between the two is limited to by swing angle limited section
Within 360 °, smaller angle range can also be limited, it had both met external connection fitting and had transmitted the rotating requires between cable, also
The rotation is defined in the angle range of setting, effectively avoid installation personnel it is unknown to state in armouring sheath when it is excessive
Rotation occurs core and turns round damage, twists off, and leads to electric signal Joint failure, influences the detection and security control of integrated circuit system.This
Technical solution also has the reliability of the connection of simple structure, general warranty signal cable line, electrical connection.
