Description

TECHNICAL FIELD

[0001] The utility model relates to underwater communication and underwater detection equipment technical field especially is related to a pressure cabin body sealing combination. BACKGROUND

[0002] In the field of underwater communication and underwater detection, the underwater acoustic transducer is the main equipment for emitting and receiving acoustic signals, and its performance is crucial to the whole communication and detection system. Under normal circumstances, the underwater acoustic transducer is designed with multiple groups of array elements in a certain array pattern, and the outgoing lines of each array element inside it are then gathered together, and after external polyurethane vulcanization, a water-tight cable with a water-tight plug is formed. The underwater acoustic transducer is usually used with a pressure cabin body, which contains a series of power supply, control and processing circuits inside, and the pressure cabin body usually has a water-tight socket designed on one side end cover. After the underwater acoustic transducer and the pressure cabin body are connected through the water-tight plug and the water-tight socket, the circuit inside the cabin can control the transducer, and functions such as emission, reception, processing and storage of underwater acoustic signals can be realized.

[0003] With the continuous development of underwater communication and detection technology, in order to improve the communication distance or improve the detection accuracy, the number of array elements of the underwater acoustic transducer is increasing. The increase of the number of array elements directly leads to the increase of the number of outgoing lines of the underwater acoustic transducer, which increases the diameter of the water-tight cable from the underwater acoustic transducer, and the minimum bending radius also increases accordingly; at the same time, due to the increase of the number of outgoing lines, the size of the water-tight plug on the underwater acoustic transducer and the water-tight socket on the pressure cabin body also increases accordingly. This increase in size has a great impact on some products with strict diameter size requirements. Due to the limitation of product diameter size, the bending radius of the water-tight cable installed on the water-tight socket of the transducer end cover is less than the minimum bending radius allowed by itself, which reduces the long-term reliability of the water-tight cable.
