Description

Transducing signal conveys the rotatable hermetically sealed connector of cable

Technical field

Present patent application is related to by small and closed detection environment 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 delivered letters from small and closed detection environment by sensing measurement signal, such as temperature change 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 ensures the safe operation of high ferro locomotive to implement accurate sensing control according to temperature and speed transmitting signal.It is existing Cable connector is sensed, 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 connect with 1 thread seal of nut, connects the plug end thread seal connection plug shell of bolt 3 12, the core 5 of cable is connected on the contact pin disk for being fixed on plug.Existing connector product in manufacture has had technical bid Quasi- seal request, in installation, the sensor ends 16 of cable have been installed in place, but the live overwhelming majority will appear connector plug contact pin 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 sensing conveying cable fix assembling, installation personnel have to scene disassemble connect bolt 3 be fixedly connected with nut 1 and The sealed connection for connecting bolt 3 and rubber sealing boot 2, will restore to connect again, can lead to two in this way after plug and terminal box grafting Big technical problem：First, plug grafting rotates, drive core with respect to cable torsion, more than length of the core in plug casing Measure very little, it is difficult to observe that the twisting states of internal core, operating personnel's in-site installation are likely to repeatedly reverse, windup-degree Several threads core therein is easily sprained, is even twisted off by accumulation, because in-site installation operation leads to great sensing detection connection peace Full problem；Second is that scene haves no alternative but, to having connected the installation operation of device dismantling, destroy the sealing technique performance of product, greatly Increase safe to use hidden danger of the sensor in high ferro, Chemical Manufacture, military equipment.

Invention content

The goal of the invention of present patent application, which is to provide, a kind of having rotary structure to adapt to grafting differential seat angle and can Limitation big angle rotary protects internal core wide-angle twisting and not remain product sealing technique in above-mentioned rotation It is required that transducing signal convey the rotatable hermetically sealed connector of cable.The transducing signal conveying cable that present patent application provides is rotatable Hermetically sealed connector technical solution, main technical content are：A kind of transducing signal conveying rotatable hermetically sealed connector of cable, knot Structure composition includes plug casing, connects bolt, nut and cable seal set, connects the cable end of bolt and nut is screwed company It connects, plug end is connect with plug casing thread seal, and cable seal set is that cable revolves core, 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, and cable revolves core Above, it protrudes from core surface and is 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 the sealing of bolt inner face is connect, and is equipped in annular groove One cooperation positioning pin, position-limiting action revolve the fixed pin of core in cable.

In the above-mentioned technical solutions, optimization technique means be cable revolve core seam allowance outer end face through rotating seal ring with connect The sealing cooperation of bolt inner face.

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, is defined the rotation of angle Rotation structure can be applicable in the terminal box grafting differential seat angle of plug and the machine cavity that works, but also effectively avoid operating personnel and exist Give specific information when can not observe connector inner case, to prevent from excessively rotating strain, twist off the phenomenon that internal core Generation.The new structure of this product makes operating personnel be not necessarily 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 fields such as petrochemical industry, aircraft sensor signals cable be reliably connected with safe and accurate conveying, ensure that high ferro, oil The operational safety of chemical industry, aircraft.
