Abstract
The utility model provides a shielding protection integrated sensor comprising a sensing probe, a cable portion, a sealed connecting flange. The flange seat of the sealed connecting flange is fixedly installed on a box body in which the sensing probe is disposed. A sealing bushing is detachably fixed on the chassis of the flange seat. The outer end of the sealing bushing is in threaded connection with a pressing cover. A sealing sleeve is arranged between the pressing cover and the flange seat. A cable portion passes through the box body, the flange seat, a sealant sleeve, and a cable hole of the pressing cover. The sealing sleeve is extruded by screwing the pressing cover so as to have a sealing effect. According to the technical scheme, the connector connecting structure of a signal transmission cable connector is eliminated and a transmission cable is guaranteed to be provided with continuous and complete shielding protection. Therefore, the transmission cable may reliably operate in operating environment with heavy vibration and strong interference.
Description
Technical field
The utility model relates to sensor handling cable lead-in wire placement technique, in particular handling cable lead-in wire placement technique in working in undesired signal environment such as being full of electromagnetism, multiple detection limit integrated sensor.
Background technology
Take the axle integrated sensor of bullet train adapted as example, its sensing probe is arranged on the axle head of axle box inside, and inside is integrated with temperature sensing portion and velocity pick-up portion, and in handling cable, wire harness lead-in wire is many, signal-transmitting cable and axle box outer cable in axle box, the electric connector on axle box connects.Because integrated sensor is in bullet train high-speed cruising state, continuing can affect grafting joint switching performance with strong vibrations, cause contact loose contact, stability and reliability variation, and adapter connector is poorly sealed close, cause the interior grease of axle box to enter connector and polluted contact, cause detection signal extremely to jeopardize traffic safety.More crucial is; because electric locomotive electric power system is to flow to track through current transformer, transformer finally by axle box wiping dish, carbon brush, wheel to form closed-loop path; sensor probe and signal transmission cable thereof are operated in the axle box space that is full of complicated electromagnetism, spark jamming; therefore to guarantee accurately normal outwards conveying of detection signal, just must guarantee that sensing probe and handling cable have complete continual shielding protection structure.But adopt the prior art of connector connecting structure, joint area becomes the interruption link of shielding protection, comprise the undesired signals such as electromagnetism thus inductive coupling enter in circuit, serious interference the detection of normal signal, make it depart from actual detected value, cause detecting in real time inefficacy, abnormal; Secondly, in axle box, handling cable corner structure is also the hidden danger position that shielding is leaked.
Summary of the invention
Goal of the invention of the present utility model be for signal-transmitting cable provide the protection of reliable electromagnetic screen and sealing property good, provide a kind of shielding protection type integrated sensor.The integrated sensor technology scheme of shielding protection type that the utility model provides, its main technical content is: the integrated sensor of a kind of shielding protection type, comprise sensing probe, cable portion and the flange that is tightly connected, in being fixedly mounted on, establishes on the casing of sensing probe the flange seat of flange of being tightly connected, Sealed casing pipe is detachably fixed on flange seat chassis, the Sealed casing pipe outer end gland that is threaded, built-in sealing shroud between gland and flange seat, cable portion is through casing, flange seat, the cable aperture of seal rubber sleeve and gland, sealing shroud plays sealing function through screwing gland extruding.
In above-mentioned overall technical architecture, described sealing shroud is cylinder cartridge type seal rubber sleeve.
The integrated sensor technology scheme of the disclosed shielding protection type of the utility model, abandon signal-transmitting cable adapter connector syndeton, signal-transmitting cable can completely be drawn casing by casing, guarantee that handling cable has continuous and complete shielding protection, screw crush seal cover by gland, by crowded swollen sealing shroud seal flange and signal-transmitting cable, improve the shielding protection performance of integrated sensor, guarantee that signal-transmitting cable wears the sealing property of casing simultaneously, enabled to work in reliably in strong vibration and strong jamming working environment.
