[0058] In order to better understand the above technical solution, the example embodiments of the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. It should be understood that the present application is not limited to the exemplary embodiments described here.

[0059] In order to adapt to the high-temperature testing scenario of the workpiece, the existing electromagnetic ultrasonic detection device is generally designed as a three-section structure, namely, a probe 1, a high-temperature connecting rod 2 and a detection instrument 3, and, in order to facilitate the replacement of the high-temperature connecting rod, the two ends of the high-temperature connecting rod 2 are detachably connected to the probe 1 and the detection instrument 3 respectively.

[0060] Please combine Figure 1 and Figure 2 , Figure 1 and Figure 2 For the existing three-stage electromagnetic ultrasonic detection device, the two ends of the high-temperature connecting rod need to be fixedly installed with circuit boards 4 respectively, and then, a docking socket 5 (male or female) is respectively arranged on the outside of each circuit board 4, one of which is used for plugging and installing with the docking socket 5 (male or female) of the detection instrument 3, and the other docking socket 5 is used for plugging and installing with the docking socket 5 (male or female) of the probe 1; at this time, the docking socket 5 is used for plugging and connecting at two places (i.e., the two outer ends of the high-temperature connecting rod 2).

[0061] Furthermore, considering the electrical connection inside the high temperature connecting rod, a cable 6 having a length greater than that of the high temperature connecting rod 2 is usually provided inside the high temperature connecting rod 2, and then, one end of the cable 6 is welded to the circuit board 4, and the other end is plugged into the docking socket 5 on the inner side of the circuit board 4 through the docking socket 5, such as Figure 2 or both ends of the cable 6 are connected to the docking socket 5 on the inner side of the circuit board 4 through the docking socket 5, such as Figure 1 As shown; it can be seen that, in this case, the electromagnetic ultrasonic detection device as a whole uses at least three plug-in connections of the docking socket 5, or at least three pairs of male / female plug-in connections.

[0062] However, frequent plugging and connecting of the docking socket will not only lead to technical problems such as severe signal interference and poor signal quality, but also cause problems such as unstable electrical connection and easy interruption of the electrical connection.

[0063] In response to the above situation, an embodiment of the present application discloses a high-temperature electromagnetic ultrasonic probe, the electrical connector inside the high-temperature electromagnetic ultrasonic probe can be electrically connected (for example, welded) to the coil excitation circuit board and the interface board at both ends respectively, without having to use a docking socket plug-in connection method. Only a pair of docking sockets need to be used when installed with the electromagnetic ultrasonic detection instrument, thereby reducing the number of docking socket plug-in connections, thereby solving the above-mentioned technical problems.

[0064] Figure 3 This is a cross-sectional structural diagram of a high-temperature electromagnetic ultrasonic probe. Figure 3A high-temperature electromagnetic ultrasonic probe comprises a probe shell 10 extending along a first direction X, a coil excitation circuit board 20 and an interface board 30 respectively mounted at two ends of the probe shell 10, and an electrical connector 40 disposed inside the probe shell 10; wherein a first docking socket 31 is provided on a side of the interface board 30 facing away from the coil excitation circuit board 20; one end of the electrical connector 40 is electrically connected to the first docking socket 31, and the other end of the electrical connector 40 is electrically connected to the coil excitation circuit board 20, so that after the first docking socket 31 is plugged and installed with the second docking socket at the end of the electromagnetic ultrasonic detection instrument 200, the coil excitation circuit board 20 is electrically connected to the electromagnetic ultrasonic detection instrument 200.

[0065] In general, the high-temperature electromagnetic ultrasonic probe of this embodiment is plugged and installed with the electromagnetic ultrasonic detection instrument to form a two-stage structure, that is, a first docking socket is provided at one end of the probe shell of the high-temperature electromagnetic ultrasonic probe, and a second docking socket is provided at the end of the electromagnetic ultrasonic detection instrument. In this way, when the high-temperature electromagnetic ultrasonic probe is plugged and installed with the electromagnetic ultrasonic detection instrument, the first docking socket and the second docking socket are plugged and installed to form an electrical connection; and the electrical connector inside the high-temperature electromagnetic ultrasonic probe of this embodiment can be directly welded to the coil excitation circuit board and the interface board at both ends thereof, and the interface board is, for example, an interface circuit board, that is, the interior of the high-temperature electromagnetic ultrasonic probe does not need to use a docking socket for plug-in connection, thereby reducing the number of docking socket plug-in connections.

[0067] The two ends of the probe housing 10 are respectively provided with a coil excitation circuit board 20 and an interface board 30, that is, the interface board is fixedly installed at one end of the probe housing for docking with the electromagnetic ultrasonic detection instrument, and the coil excitation circuit board is installed at the other end of the probe housing; for example, the interface board can be fastened and installed by screws, etc.; and it can be understood that the end of the probe housing on which the coil excitation circuit board is installed should also be provided with a magnet and a high-frequency coil, etc. The specific installation method of the magnet, the high-frequency coil and the coil excitation circuit board can be found in the relevant description below, and is not limited here.

[0069] Specifically, please combine Figure 3In this embodiment, a first docking socket is provided on the side of the interface board facing away from the coil excitation circuit board, and then the two ends of the electrical connection member (for example, a connecting cable) are respectively welded to the coil excitation circuit board and the first docking socket; it can be understood that in this way, after the first docking socket is plugged and installed with the second docking socket at the end of the electromagnetic ultrasonic detection instrument, the coil excitation circuit board is electrically connected to the electromagnetic ultrasonic detection instrument.

[0070] Of course, for easy operation, the length of the electrical connector should generally be greater than the length of the probe housing.

[0071] In one possible implementation, for example, an adapter may be provided on the side of the coil excitation circuit board facing the interface board, that is, one end of the electrical connector may be welded to the coil excitation circuit board by specifically welding it to the adapter of the coil excitation circuit board.

[0072] The embodiment of the present application provides a high-temperature electromagnetic ultrasonic probe and a high-temperature electromagnetic ultrasonic detection device. The high-temperature electromagnetic ultrasonic probe includes a probe shell, and a coil excitation circuit board and an interface board are respectively installed at two ends of the probe shell. An electrical connector is provided inside the probe shell, that is, the electrical connector is located between the coil excitation circuit board and the interface board; wherein, an adapter is provided on a side of the coil excitation circuit board facing the interface board, and a first docking socket is provided on a side of the interface board facing away from the coil excitation circuit board; and, the two ends of the above-mentioned electrical connector are respectively electrically connected to the adapter and the first docking socket; in this way, it can be understood that when the high-temperature electromagnetic ultrasonic probe is plugged and installed with the electromagnetic ultrasonic detection instrument, the first docking socket can be plugged and installed with the second docking socket at the end of the electromagnetic ultrasonic detection instrument, so that the coil excitation circuit board can be electrically connected to the electromagnetic ultrasonic detection instrument.

[0073] It can be seen that through the above-mentioned structural setting, the high-temperature electromagnetic ultrasonic probe of this embodiment can form a two-stage detachable structure with the electromagnetic ultrasonic detection instrument. Compared with the existing three-stage structure in which a high-temperature connecting rod is detachably set between the probe and the detection instrument, the two ends of the electrical connector in this embodiment can be directly electrically connected (for example, welded) to the adapter of the coil excitation circuit board and the first docking socket for plugging and installing with the electromagnetic ultrasonic detection instrument, respectively. There is no need to set docking sockets at both ends of the electrical connector, but only need to use the docking socket to install between the interface board and the electromagnetic ultrasonic detection instrument, which reduces the number of plug-in connections of the docking socket, thereby solving the technical problem of severe signal interference and poor signal quality caused by a large number of plug-in connections of the docking socket.

[0074] Regarding the above-mentioned first docking socket 31 and adapter seat 21, in a possible implementation manner, the first docking socket 31 includes a docking portion 311 and a first pin 312, the docking portion 311 is arranged on the side of the interface board 30 facing away from the coil excitation circuit board 20, the first pin 312 penetrates the interface board 30 and is protruded relative to the side of the interface board 30 facing the coil excitation circuit board 20, so that one end of the electrical connector 40 is electrically connected to the first pin 312; the adapter seat 21 includes an adapter portion 211 and a second pin 212, the adapter portion 211 is arranged on the side of the coil excitation circuit board 20 facing the interface board 30, and the second pin 212 is exposed from the adapter portion 211, so that the other end of the electrical connector 40 is electrically connected to the second pin 212.

[0075] That is, on the one hand, see Figure 3 The first docking socket can be welded to the interface board through the first pin, for example, wherein the docking portion of the first docking socket is located on the side of the interface board facing away from the coil excitation circuit board, and the first pin penetrates the interface board and is protrudingly arranged, so that one end of the electrical connector can be conveniently welded to the first pin.

[0076] On the other hand, combined Figure 3 and Figure 4 The adapter can be soldered to the coil excitation circuit board through the second pin, wherein the adapter portion of the adapter is located on the side of the coil excitation circuit board facing the interface board, and the second pin is exposed at the adapter portion, that is, also located on the side of the coil excitation circuit board facing the interface board. In this way, the other end of the electrical connector can be conveniently soldered to the second pin.

[0077] In one possible implementation, please combine Figure 3 and Figure 5 The probe housing 10 is provided with an end of the interface plate 30 and is installed with the electromagnetic ultrasonic testing instrument 200 through a detachable structure; wherein the detachable structure includes a screw structure 13 or a buckle structure; for example Figure 3 The screw structure 13 at the end of the probe housing 10 is shown; of course, it can be understood that the end of the probe housing can also be detachably connected to the electromagnetic ultrasonic testing instrument through a snap-fit ​​structure.

[0078] Regarding the specific structure of the above-mentioned probe shell 10, in one possible implementation, the probe shell 10 includes a first shell 11 and a second shell 12 extending along a first direction X; wherein the first shell 11 and the second shell 12 are fixedly installed; the interface board 30 is fixedly installed at one end of the first shell 11 away from the second shell 12, and a magnet 50 is installed inside the second shell 12, and a high-frequency coil 60 and a coil excitation circuit board 20 are respectively provided at both ends of the magnet 50 along the first direction X, and the high-frequency coil 60 is electrically connected to the coil excitation circuit board 20.

[0079] In this embodiment, for easy assembly, the probe housing 10 may be composed of a first housing 11 and a second housing 12 .

[0080] The interior of the first housing 11 corresponds to the above-mentioned connecting cable, that is, the electrical connector; the length of the first housing can be set according to actual needs. Generally speaking, refer to Figure 5 and Figure 6 The first shell can be provided with two lengths, namely, a normal type and an extended type, so as to meet various high temperature detection needs.

[0081] The interior of the second shell corresponds to the above-mentioned magnet, high-frequency coil and coil excitation circuit board; wherein, the two ends of the magnet along the first direction are the high-frequency coil and the coil excitation circuit board respectively, and the coil excitation circuit board is electrically connected to the high-frequency coil; that is, the coil excitation circuit board should be located at one end of the second shell close to the first shell.

[0082] Regarding the specific structure of the fixed installation of the first shell 11 and the second shell 12, in one possible embodiment, the second shell 12 includes an inner shell 121 and an outer shell 122 that are nested; wherein, the first shell 11 is provided with a plurality of mounting ears 111 at the circumferential end portion facing the inner shell 121, and the mounting ears 111 are used to be fastened to the inner shell 121 by screws after being plugged into and installed with the inner shell 121, so that the first shell 11 and the second shell 12 are fixedly installed; and, the outer shell 122 covers the position of the screws after being nested with the inner shell 121.

[0083] In this embodiment, the first housing 11 and the inner shell 121 of the second housing 12 may be installed first.

[0084] Specifically, see Figure 4 A plurality of mounting ears 111 are provided at the circumferential end of the first shell, and the first shell 11 and the inner shell 121 are plugged and installed. At this time, the mounting ears 111 are, for example, inserted into the inner shell 121, and then, the mounting ears 111 and the inner shell 121 can be fastened and installed by screwing in the radial direction, that is, the first shell 11 and the inner shell 121 are fastened and installed by screws.

[0085] Then, the outer shell 122 and the inner shell 121 are nested and installed.

[0086] Specifically, see Figure 4 The outer shell 122 and the inner shell 121 can be nested and installed, for example, through a threaded structure 123, that is, the outer shell can be screwed in. It should be noted here that after the outer shell is nested and installed with the inner shell, the outer shell should cover the screws for fastening the mounting ears and the inner shell.

[0087] That is to say, through the structure of hiding the screws, this embodiment does not intend to prompt the user to disassemble the first shell and the second shell during use.

[0088] Regarding the above-mentioned coil excitation circuit board 20, in one possible implementation, the coil excitation circuit board 20 includes a flexible circuit board; wherein a pressure plate 70 is fixedly installed at the end position of the first shell 11 close to the second shell 12, and the pressure plate 70 is used to abut against the flexible circuit board after the first shell 11 and the second shell 12 are fixedly installed, and the pressure plate 70 is provided with a first through hole 71 for the adapter 21 to pass through.

[0089] That is, in order to facilitate the electrical connection with the high-frequency coil, the above-mentioned coil excitation circuit board can be, for example, a flexible circuit board; further, in this embodiment, a pressure plate can be set at the end position of the first shell close to the second shell. In this way, it can be understood that after the first shell 11 and the second shell 12 are fixedly installed, the pressure plate 70 can be used to abut against the flexible circuit board. At this time, the pressure plate 70 should be provided with a first through hole 71 for the adapter 21 on the flexible circuit board to pass through.

[0090] Of course, in other embodiments, in combination with the plurality of mounting ears provided at the circumferential end of the first shell, if the radius of the pressure plate is larger than the circumferential radius of the mounting ears, the pressure plate 70 should also be provided with a second through hole 72 at the position corresponding to each mounting ear 111 for the mounting ear 111 to pass through.

[0091] In combination with the above embodiments, it can be seen that the assembly of the high temperature electromagnetic ultrasonic probe can be, for example:

[0092] The first step is to fasten the interface board to one end of the first housing;

[0093] Step 2: solder one end of the connecting cable to the first pin of the first docking socket on the interface board;

[0094] The third step is to assemble the magnet, the high frequency coil and the coil excitation circuit board and place them in the inner shell of the second shell;

[0096] Step 5: Install the first shell, the pressure plate and the inner shell by plugging them together, and fasten the mounting ears of the first shell to the inner shell;

[0097] Step 6: Screw it into the outer shell.
