Detailed Description

The above objects, features and advantages of the present invention will become more apparent from the following detailed description of the present invention with reference to the accompanying drawings, which are illustrated in fig. 1 to 9.

The special intelligent cable assembly for the in-pipeline detector adopted by the embodiment mainly comprises a connector male head 1, a connector female head 2, a circuit board 3, a shell 4 and a fastening pressing plate 5. The male connector 1 of the intelligent cable assembly is manufactured in an integral vulcanization mode, and the male connector 1 is connected with various probes of the detector in the pipeline through cables.

The female connector 2 is connected to a circuit board 3 and is integrally disposed in a housing 4 along with the circuit board. The circuit board 3 mainly comprises an isolation chip, an FPGA system and a peripheral circuit connected with the FPGA system, and comprises a power supply system and a clock system. The male connector 1 is inserted into the corresponding female connector 2, and the male connector 1 and the female connector 2 are fixed in a compression joint mode through the fastening pressing plate 5, so that the connection position of the male connector 1 and the female connector 2 is firmly prevented from being separated.

The connector female 2 and the circuit board 3 in this embodiment are connected as follows:

in this embodiment, 8 female seats with 8 cores are adopted as female heads of the connector, and the output end of the female seat with 8 cores is sequentially connected with the signal isolation unit, the FPGA system, the single-ended input-to-differential output unit and the female seat with 8 cores. The eight female connector heads 2 are used for receiving detection data of each probe of the in-pipeline detector, wherein four female connector heads 2 are connected with the first isolation chip U5, and the other four female connector heads 2 are connected with the second isolation chip U6. As shown in fig. 3-8, the SCK1_ N pin of the 8-core mother socket is connected to the Y3 pin of the first isolation chip U5, the MOSI1_ N of the 8-core mother socket is connected to the Y3 pin of the first isolation chip U5, and the remaining 7 8-core mother sockets have the same connection mode, which is not described herein again.

The output pins SCK1_ N and MOSI1_ N of the first isolation chip U5 are connected to IO81 and IO82 pins of the FPGA. Similarly, the output pin of the second isolation chip U6 is also connected to the IO terminal of the FPGA. DMOSI pins and DSCK pins of the FPGA are connected with a single-end input switching and inserting output unit (with the model number of FIN1027K8X), DMOSI _ N, DMOSI _ P, DSCK _ N and DSCK _ P pins of the single-end input switching and inserting output unit are connected with the input end of a single 8-core female socket, and the output end of the single 8-core female socket J4 outputs signals to an external component.
