The present invention relates to a reference signal source module resistant to an external vibration environment. The reference signal source module comprises: an oscillator which outputs a reference frequency signal; a printed circuit board on which the oscillator is mounted; a frame which has a rectangular shape, on which the printed circuit board is mounted, has a structure with an outer portion of a rectangular vertex and respectively forms a first groove to insert a screw at the cut portion; a body which has a rectangular shape, has a structure enclosing the frame, forms a second groove, respectively, to insert a screw at the inner portion of the rectangular vertex and has a structure physically separated from the frame; and four buffer connectors which connect the body and the frame. An embodiment of the present invention can provide a reference signal source module resistant to an external vibration environment which can provide stable performance under a vibration by improving the structure which has trouble in the reference frequency circuit structure and is vulnerable to external environment (vibration/shock). |
