Conversion cable for connecting wet plugging interface temperature-salinity-depth instrument and standard interface transmission cable

Abstract

The invention belongs to the field of marine science investigation, and particularly relates to a conversion cable for connecting a wet plugging interface temperature-salinity-depth instrument and a standard interface transmission cable. A wet plugging female interface and a standard male interface are respectively connected to two ends of the cable through a rubber vulcanization method, the wet plugging female interface is provided with two wire holes, the standard male interface is provided with a thin wire pin and a thick wire pin, the cable comprises two mutually insulated wires, and eachwire hole is in conduction connection with one wire pin through one wire; positioning devices are correspondingly arranged on the wet plugging female interface and the wet plugging male interface of the SBE type temperature-salinity-depth instrument of the wet plugging interface connected with the wet plugging female interface; and the wet plugging female interface is sleeved with a wet plugging interface fixing cover, and the standard male interface is sleeved with a standard interface fixing cover. According to the invention, the original transmission cable does not need to be damaged, the wet plugging transmission interface of the temperature-salinity-depth instrument can be rapidly changed into a standard transmission interface of the temperature-salinity-depth instrument, marine scientific investigation is facilitated, and the industrialization prospect is wide.

Description

technical field [0001] The invention belongs to the field of marine scientific investigation, in particular to a conversion cable for connecting a temperature, salt and depth meter with a wet plug interface and a transmission cable with a standard interface. Background technique [0002] Driven by the national ocean strategy and the deep sea development plan, various marine disciplines have gradually developed and moved towards the ocean. The temperature and salinity depth instrument is used to measure the changes of seawater temperature, salinity and other parameters with depth, which is of great significance to the research of ocean flow field, seawater chemical properties and marine ecosystem. The SBE9 CTD produced by Sea-Bird (Flying Bird) Company of the United States is the most accurate and most commonly used temperature, salinity and depth instrument in ocean observation. Instruments are relatively common, so the signal transmission cable used to connect the temperat...
