The present patent application provides a kind of transducing signal conveying rotatable hermetically sealed connector of cable, its structure composition includes plug casing, connection bolt, nut and cable seal set, the cable seal set revolves core for cable, nut inner wall is equipped with a ring platform, the cable side of land is correspondingly formed annular groove, on cable rotation core, protrude from core surface and be equipped with a positioning pin, positioning pin revolves core with cable and falls into annular groove by the notch that the holding locating pin in land passes through.The technical program effectively avoids operating personnel and gives clear and definite information when that can not observe connector inner case, to prevent excessively rotation from spraining, twisting off the generation of the phenomenon of internal core, and the scene of realizing need not disassemble connector, accurately and rapidly complete plug grafting technical purpose, ensure that high ferro, petrochemical industry, aircraft it is safe for operation.
Description
Technical field
The detection environment that present patent application is related to by small and closes is by sensing measurement signal, such as temperature pick-up signal, speed
The connector that the inserting modes such as pick-up signal, pressure inverting signal are drawn.
Background technology
Transducing signal leading-out connector is that sensing measurement signal, such as temperature change are delivered letters from detection environment that is small and closing
Number, the connection product drawn by plugs and sockets mode such as speed transmitting signal, pressure inverting signal, be widely used in high ferro,
The technical fields such as marine electrical motors, power station motor, petrochemical industry.By taking high ferro wheel tooth shaft case as an example, temperature or velocity sensor
Sensing pick-up signal need to convey cable and connector by it and draw axletree end gearbox, be transferred to external detection control
Unit, to implement accurate sensing control according to temperature and speed transmitting signal, ensures the safe operation of high ferro locomotive.It is existing
Cable connector is sensed, its structure is as shown in Figure 1, sensing cable end is fixed with rubber sealing boot 2, including rubber sealing boot 2 is consolidated
Level pressure enters to connect in bolt 3, is connected with 1 thread seal of nut, connects the plug end thread seal connection plug housing of bolt 3
12, the core 5 of cable is connected on the contact pin disk for being fixed on plug.Existing connector product when dispatching from the factory has possessed technical bid
Quasi- seal request, in installation, the sensor ends 16 of cable have been installed in place, but connector plug contact pin occurs in the live overwhelming majority
Work machine cavity terminal box between must just be rotated there are certain differential seat angle, connector after could with terminal box grafting, because even
Connect device and the fixed assembling of sensing conveying cable, installation personnel have to scene disassemble connection bolt 3 be fixedly connected with nut 1 and
The sealed connection of bolt 3 and rubber sealing boot 2 is connected, plug is connected with recovering again after terminal box grafting, can so cause two
Big technical problem：First, plug grafting rotates, core is driven with respect to cable torsion, more than length of the core in plug casing
Measure very little, it is difficult to which, it was observed that the twisting states of internal core, operating personnel's in-site installation is likely to repeatedly reverse, windup-degree
Several threads core therein is easily sprained, even twisted off by accumulation, because in-site installation operation causes great sensing detection connection peace
Full problem；Second, the installation operation disassembled to connector is haveed no alternative but at scene, the sealing technique performance of product is destroyed, greatly
Add safe to use hidden danger of the sensor in high ferro, Chemical Manufacture, military equipment.
The content of the invention
The goal of the invention of present patent application, which is to provide, a kind of has rotary structure to adapt to grafting differential seat angle and can
Limitation big angle rotary, protect internal core wide-angle twisting and not remain product sealing technique in above-mentioned rotation
It is required that transducing signal conveying the rotatable hermetically sealed connector of cable.The transducing signal conveying cable that present patent application provides is rotatable
Hermetically sealed connector technical solution, its main technical content are：A kind of transducing signal conveys the rotatable hermetically sealed connector of cable, it is tied
Structure composition includes plug casing, connects bolt, nut and cable seal set, connects the cable end of bolt and nut is screwed company
Connect, plug end is connected with plug casing thread seal, and cable seal set revolves core for cable, is affixed to signal conveying cable
The fixing seal set of line end, nut inner wall are equipped with a ring platform, and the cable side of land is correspondingly formed annular groove, cable rotation core
Above, protrude from core surface and be equipped with a positioning pin, the notch that positioning pin is passed through with cable rotation core by the holding locating pin in land
Annular groove is fallen into, after assembling, cable revolves core seam allowance outer end face and coordinates with being connected the sealing of bolt inner face, is equipped with annular groove
One coordinates positioning pin, position-limiting action in the fixed pin of cable rotation core.
In the above-mentioned technical solutions, its optimization technique means revolves the rotated sealing ring of core seam allowance outer end face with being connected for cable
The sealing of bolt inner face coordinates.
Transducing signal disclosed in present patent application conveys the rotatable hermetically sealed connector technical solution of cable, and cable revolves core in spiral shell
Rotatable and its rotation angle is made because of the setting of fixed pin and is defined in small angle range in cap, it is defined the rotation of angle
Rotation structure can be applicable in plug and the terminal box grafting differential seat angle for the machine cavity that works, but also effectively avoid operating personnel and exist
Give clear and definite information when can not observe connector inner case, to prevent excessively rotation from spraining, twisting off the phenomenon of internal core
Generation.The new structure of this product makes operating personnel to disassemble connector at the scene, still can accurately and rapidly complete
Plug grafting, original sealing performance when ensureing the complete of cable and not damaging, safeguard connector product export, ensure high ferro,
The field such as petrochemical industry, aircraft sensor signals cable be reliably connected with safe and accurate conveying, ensure that high ferro, oil
Chemical industry, aircraft it is safe for operation.
