Description
Technical Field
The application belongs to the field of mechanical structure design, and particularly relates to a module connector mounting structure based on floating installation.
Background
The internal module of the radar scanner is interconnected with the interfaces of internal and external equipment through cables and connectors to transmit photoelectric signal data. The internal module is generally a self-contained drop cable. The connection of the cable to the connector is mainly in the following two ways:
the first method is as follows: and (5) field head retracting. After the internal module is installed inside the scanner shell, the length of the cable is specified on site according to the butt joint space position of the connector, and then the connector and the cable are welded. Due to the fact that the internal volume of the radar scanner is limited, the operation space for welding the connector and binding the cable is limited, and the man-machine efficiency is poor.
The second method comprises the following steps: and (4) pre-closing the head. After the internal module pre-estimates the cable size, the connector is soldered to the cable and then installed inside the scanner. Cable reserve length if the estimate is inaccurate, the cable is likely to be too long or too short. Meanwhile, the cable binding operation is limited by the size of the inner space of the scanner housing.
The two cable and connector mounting modes of the radar scanner module have the defects of complex module mounting and dismounting, poor module maintainability, low modularization and low integration degree.
