Description

Technical Field

[0001] The utility model relates to the field of electrical equipment, in particular to a non-pin type cable plug and socket. Background Art

[0002] The hydraulic automatic grab beam used in the gate-type gate hoist of a hydropower station is often used in a humid underwater environment to grab and open the gate. It is very important to ensure that the underwater pin movement, arrival signal and other various action signals of the grab beam are normal. Failures in the electrical signal system of the grab beam directly affect the safe and normal opening and closing of the gate. Failures that occur during underwater work may even require diving operations with higher safety risks. Defects in the grab beam cable plug socket account for a large proportion of failures in the electrical signal system of the grab beam. The existing grab beam cable plug socket adopts a multi-core pin type. The internal conductor plug of the pin-type cable plug socket adopts a cylindrical metal pin with a smaller diameter. During the plug-in and unplugging process, it is easy for the pin to be deformed and tilted by external force, resulting in mismatch between the pin and the socket of the plug socket. In severe cases, the tiny pin is prone to breakage. Utility Model Content
