Description

Board card power connector and board card assembly Technical Field The invention relates to the technical field of semiconductor automatic test equipment, in particular to a board card power connector and a board card assembly. Background In semiconductor automated test equipment, the power supply process of the board card usually involves manually connecting the board card to the power line drawn from the bus bar beside the equipment after the board card is inserted into the test head. The traditional power supply connection mode has the obvious defects that when the board card is installed or detached, the plugging operation of the power supply line is needed to be completed, so that the process is tedious, and connection instability or equipment damage is easy to cause due to human error. Meanwhile, the power line is limited by the physical structure, the turning radius is larger, and the power line occupies too much space in the equipment, so that the equipment is loose in layout, low in space utilization rate, disordered in internal circuit and lack of simplicity in an operation interface, and the testing efficiency and the maintenance convenience are seriously affected. Disclosure of Invention The invention aims to provide a board power connector and a board assembly, which are used for reducing operation threshold and simplifying the front interface of a board. In order to solve the technical problems, the invention provides a board power connector and a board assembly. The invention relates to a power connector of a board card, which is used for being mounted on a front panel of the board card and comprises a connector body, and a first electric contact assembly and a second electric contact assembly which are arranged in the connector body and are electrically connected; The connector body is also provided with a fixed connection part which is used for fixedly connecting the connector body and the front panel of the board card; The first electric contact assembly is used for being electrically connected with a PCB of the board card; The second electrical contact assembly is capable of positional float in multiple directions relative to the connector body; The second electrical contact assembly is configured to automatically interface with and form an electrical connection with an outgoing power cord of a bus bar of a device when the board card is inserted into a device slot. Further, the second electrical contact assembly includes at least two conductive blocks and a resilient contact disposed on the conductive blocks. Further, the elastic contact piece is a reed.
