Description of the invention: [Technical field to which the invention pertains] [1] The present invention relates to a detecting device, and more particularly to an electromagnetic interference detecting device. [Prior Art] [_ t sub-products must be tested by electromagnetic interference (EUctr. netic Interference, EMI) before they appear in court, and they are qualified products. In addition, in the early stage of development of electronic products such as circuit boards, it is necessary to pass through small parts. Detecting to find problems in the design, especially to find out the specific location and radiation intensity of the noise signal source in the board, in order to improve as soon as possible. Conventional flaw detection devices typically include a detector, a signal receiving device, and a signal display device. In the measurement process of small parts, the noise signal, especially the low frequency noise signal, is generally weak. To ensure effective measurement, it is often necessary to directly connect the detector to the signal receiving device to transmit signals. However, the use of wired transmission of signals is inconvenient for EMI detection of small components, wasting wires and has a limited working range. If wireless transmission is used, a signal amplifier and a transmitting antenna are installed in the detector. The detector in the detector contacts the signal source, transmits the signal to the signal amplifier, and then converts the noise signal into a corresponding wireless. The signal is sent by the transmitting antenna. The wireless transmission mode can expand the working range, but requires a signal amplifier, which has a complicated structure and high cost.

The portion of the wire wound around the transmitting portion 113 is the antenna end 121, which is equivalent to a transmitting antenna, and transmits the wireless signal converted by the wire 12. In order to increase the number of windings and ensure the strength of the wireless signal, in the present embodiment, a transmission portion 122 is added between the antenna end 121 and the probe 13, and is wound around the extending portion 112 of the insulating rod 11. To avoid signal loss, the wire 12 is preferably made of a conductor having a high electrical conductivity. In the present embodiment, the wire 12 is made of metallic silver. [0011] The probe 13 is connected to one end of the wire 12 and extends from one end of the insulating rod 11 in a direction away from the insulating rod 11.

September. 30 days to replace the page pin 13 The signal source 40 in the small component is contacted, and the noise signal is amplified and transmitted to the antenna terminal 121 by the transmission unit 122. The antenna terminal 121 amplifies the noise signal again and sends the signal, and the signal receiving device 20 receives the noise. After the signal is transmitted, it is directly transmitted to the signal display device 30. The target noise signal source 40 can be found by the frequency and intensity of the noise signal displayed by the signal display device 30. Since the probe 13 has a small contact surface, it can be applied to a place where the noise signal source 40 is dense.
