[0084] The probe 110 has a detection part 111 and a fixing part 112 disposed opposite to each other. The detection part 111 and the fixing part 112 can be integrally formed to reduce production costs. The detection part 111 is used to test the sample under test. When the probe assembly 10 is used to test the parameters of the sample under test, the detection part 111 of the probe 110 contacts the sample under test to perform the test. Understandably, the detection part 111 can transmit the electrical signal from the sample under test to the electrode device, thereby acquiring and analyzing the electrical signal to test the parameters of the sample under test.

Understandably, the clamp 120 fixes the positions of the fixing part 112 and the conductive connection part 131, thereby ensuring stable electrical signal exchange between the fixing part 112 and the conductive connection part 131 during testing.
[0086] The probe assembly 10 also includes a wire 130. When the probe assembly 10 is used to test the parameters of the sample under test using the probe holder 1, the probe 110 is electrically connected to the current device 40 on the probe holder 1 via the wire 130, thereby realizing the exchange of electrical signals between the probe 110 and the current device 40. Understandably, the detection unit 111 conducts current to the sample under test via the wire 130 to test the parameters of the sample under test when receiving current. Understandably, the sample under test conducts electrical signals to the current device 40 via the wire 130 to achieve the acquisition and analysis of the electrical signals from the sample under test. The wire 130 includes a conductive connection part 131, which is electrically connected to the fixing part 112 to realize the electrical connection between the wire 130 and the probe 110.
[0087] To clearly illustrate the beneficial effects of the technical solution of this application, related technologies are introduced here. The probe assembly 10 in the related technologies operates in a test environment with a temperature between -269°C and 200°C. When the temperature of the test environment exceeds 200°C, the heat from the test environment will be conducted to the lead wire 130, causing the lead wire 130 to overheat and be damaged, interfering with the test results of the probe assembly 10 on the sample being tested. This also affects the service life of the lead wire 130 and the probe assembly 10.
[0088] The probe assembly 10 provided in this application includes a first heat insulation member 140. The first heat insulation member 140 is located on the outer periphery of the portion of the conductive body 132 near the conductive connection portion 131, and accommodates the portion of the conductive body 132 near the conductive connection portion 131. It is understood that the first heat insulation member 140 may be, but is not limited to, a tubular structure, sleeved on the outer periphery of the portion of the conductive body 132 near the conductive connection portion 131. When the probe assembly 10 is used to test the parameters of the sample under test in a high-temperature testing environment (e.g., 200℃~500℃), the first heat insulation member 140 can achieve thermal isolation between the conductive body 132 and the high-temperature testing environment, thereby preventing the conductive body 132 from overheating and being damaged, and increasing the service life of the wire 130 and the probe assembly 10. The first heat insulation member 140 may be an insulating first heat insulation member; optionally, the insulating first heat insulation member may be a ceramic first heat insulation member.
[0089] To clearly illustrate the beneficial effects of the technical solution of this application, the relevant technologies are described again here. In the relevant technologies, the electrical connection between the components of the probe assembly 10 is usually achieved by soldering during manufacturing. However, the solder in the soldering process is unstable at high temperatures. When the probe assembly 10 is continuously used to test the sample in a test environment of 200℃~500℃, the solder in the soldering process of the relevant technologies is prone to melting, causing damage to the probe assembly 10. The first high-temperature resistant fastening component 150 and the second high-temperature resistant fastening component 160 in the probe assembly 10 provided in this application have the characteristic of not easily melting at high temperatures, so that the probe assembly 10 can be used to test the sample in a test environment of 200℃~500℃. It can be understood that the probe assembly 10 provided in this embodiment has a wide temperature application range and can also be used in low temperature environment, normal temperature environment and high temperature environment. The temperature environment t of the probe assembly 10 provided in this embodiment satisfies: -269℃ <t≤500℃。
[0090] The first high-temperature resistant fastening assembly 150 is used to press-fit and fix the fixing part 112 to the clamp 120. It is understood that the first high-temperature resistant fastening assembly 150 may be, but is not limited to, a combination of a high-temperature resistant screw, a high-temperature resistant bolt, a combination of a high-temperature resistant screw and a high-temperature resistant nut, or a combination of a high-temperature resistant bolt and a high-temperature resistant nut. Optionally, the first high-temperature resistant fastening assembly 150 is correspondingly disposed with respect to the portion of the clamp 120 near the fixing part 112, and penetrates the clamp 120 to achieve the press-fit fixation between the clamp 120 and the fixing part 112. The electrical connection method of the first high-temperature resistant fastening assembly 150 and the press-fit fixation can avoid the melting of solder in the soldering process used in related technologies, thereby making the probe assembly 10 more stable and less prone to damage when tested in high-temperature testing environments.
[0091] The second high-temperature resistant fastening assembly 160 is used to press-fit and fix the conductive connection portion 131 to the clamp 120. It is understood that the second high-temperature resistant fastening assembly 160 can be, but is not limited to, a combination of a high-temperature resistant screw, a high-temperature resistant bolt, a combination of a high-temperature resistant screw and a high-temperature resistant nut, or a combination of a high-temperature resistant bolt and a high-temperature resistant nut. Optionally, the second high-temperature resistant fastening assembly 160 is correspondingly disposed to the portion of the clamp 120 opposite to the fixing portion 112, and penetrates the clamp 120 to achieve the press-fit fixation of the clamp 120 and the conductive connection portion 131. The electrical connection method of the second high-temperature resistant fastening assembly 160 and the press-fit fixation can avoid the melting of solder in the soldering process used in related technologies, thereby making the probe assembly 10 more stable and less prone to damage when tested in high-temperature testing environments.
[0092] In summary, the probe assembly 10 provided in this application includes a probe 110, a clamp 120, a wire 130, a first heat insulation member 140, a first temperature-resistant fastening assembly 150, and a second temperature-resistant fastening assembly 160. The probe 110 has a detection portion 111 and a fixing portion 112 disposed opposite to each other. The detection portion 111 is used to test the sample. The clamp 120 houses the fixing portion 112 to fix the probe 110; the clamp 120 presses and fixes the conductive connection portion 131 of the wire 130 to connect the wire 130 and the clamp 120. The conductive connection portion 131 of the wire 130 is connected to the fixing portion 112 to realize electrical signal exchange between the probe 110 and the wire 130. The first heat insulation element 140 is located on the outer periphery of the portion of the conductive body 132 near the conductive connection portion 131, and accommodates the portion of the conductive body 132 near the conductive connection portion 131, thereby reducing heat transfer between the portion of the conductive body 132 near the conductive connection portion 131 and the test environment, thus preventing the wire 130 from overheating and being damaged when the probe assembly 10 is used to test the parameters of the sample under high temperature conditions. The first high-temperature resistant fastening assembly 150 is used to press and fix the fixing portion 112 to the clamp 120, and the second high-temperature resistant fastening assembly 160 is used to press and fix the conductive connection portion 131 to the clamp 120. The first high-temperature resistant fastening assembly 150 and the second high-temperature resistant fastening assembly 160 and the pressing and fixing method make the probe assembly 10 more stable and less prone to damage when tested in high-temperature test environments.

The wire 130 connects the clamp 120 and the current device 40 in the probe holder 1, but cannot fix the position of the probe assembly 10 and the current device 40. One end of the support rod 170 is spaced apart from the clamp 120, and the other end is used to connect to the displacement stage 30 in the probe holder 1. This allows for the fixation of the position of the probe assembly 10 and the displacement stage 30, providing support for the probe assembly 10.

Optionally, the second heat insulation element 190 is a ceramic tube heat insulation element. The second heat insulation element can reduce the heat transfer from the test environment to the support rod 170, and at the same time, it can also serve as insulation to prevent the current in the wire 130 from being conducted to the support rod 170 and damaging the probe assembly 10 when the probe assembly is used to test the characteristic parameters of the sample under test when a large current passes through it.
[0096] The probe assembly 10 further includes a transition member 180, which is located between the support rod 170 and the clamp 120, with one end of the transition member 180 connected to that end of the support rod 170. Understandably, the transition member 180 simultaneously accommodates the end of the support rod 170 facing the clamp 120 and the end of the second heat insulation member 190 facing away from the clamp 120. Optionally, the transition member 180 includes a first transition portion and a second transition portion. The first transition portion is fixedly connected to the support rod 170, and the second transition portion is fixedly connected to the second heat insulation member 190, thereby achieving a fixed connection between the support rod 170 and the second heat insulation member 190.

The portion of the second surface 122a facing the probe slot 121b can abut against the surface of the fixing part 112 facing the first fixing member 122, allowing the probe 110 to be stably fixed to the clamp 120. The detection portion 111 of the probe 110 extends from the probe slot 121b for testing the sample. Understandably, the base 121 and the first fixing member 122 cooperate to receive and fix the fixing part 112 of the probe 110. When the plurality of probes 110 and the clamp 120 are assembled, the probe slots 121b can further accurately determine the installation position of the probe 110.
