Description

External box and external device with same Technical Field The present invention relates to an external box, and more particularly to an external box with a display card and an external device with the external box. Background The notebook computer is limited by the internal space, and often cannot be provided with a high-performance display card to meet the requirements of users. In order to solve the problem, display card external devices are appeared on the market. The independent display card can be connected to the notebook computer in an external connection mode so as to improve the display efficiency. The display card external device on the market at present occupies a small space, but can only be used with a notebook computer or a computer host provided with a specific connection port, and the application of the display card external device is greatly limited. Disclosure of Invention The present invention provides an external connection box and an external connection device having the external connection box, so as to solve at least one of the above problems. The invention provides an external box which is suitable for installing a display card and a main board and is suitable for being connected to a computer device for operation. The external box comprises a shell and a circuit board. The circuit board is arranged at the bottom of the shell and comprises an external connector, a first connector and a second connector. The external connector is arranged at one edge of the circuit board and is suitable for being connected to a computer device. The first connector is arranged on the upper surface of the circuit board and is electrically connected with the external connector, and the first connector is suitable for mounting the display card. The second connector is arranged on the circuit board and is electrically connected with the first connector, and the second connector is suitable for installing the mainboard. The invention also provides an external device which is suitable for being connected to a computer for operation. The external device comprises a display card, a main board and an external box. The external box comprises a shell and a circuit board. The circuit board is arranged at the bottom of the shell and comprises an external connector, a first connector and a second connector.
