[0013] According to one aspect of this application, a resistance testing apparatus is provided, including the resistance testing fixture described above.
[0014] The beneficial effects of this application are as follows: Unlike existing technologies, this application provides a resistance testing fixture, including a base, a fixing block, a first sliding assembly, a second sliding assembly, a first probe, and a second probe. The fixing block, the first sliding assembly, and the second sliding assembly are disposed on the base. The fixing block is used to fix the device under test. The first sliding assembly and the second sliding assembly are respectively located on both sides of the fixing block. The first probe is disposed on the first sliding assembly, which assists in moving the first probe relative to the base, allowing the first probe to move closer to and away from the fixing block.

In the process of testing the resistance of a component under test (DUT), a resistance testing fixture is placed on a resistance testing machine. The positive and negative terminals of the resistance testing machine are connected to the first and second probes, respectively. The DUT is fixed to a fixed block. The first probe is moved closer to the fixed block until it touches one end of the DUT, and the second probe is moved closer to the fixed block until it touches the other end of the DUT. This allows for a relatively quick completion of the resistance test, and the contact points between the first and second probes and the DUT are relatively fixed, reducing the likelihood of deviation and resulting in good consistency of the test results. Therefore, the resistance testing fixture of this application can improve the efficiency of resistance testing for metal products and the consistency of the test results. Attached Figure Description

[0031] Resistance testers can detect the resistance of components. Some components are metal products. In the process of detecting their resistance, the metal product is mainly fixed by a fixture, and then the positive and negative terminals of the resistance tester are manually held to contact the two ends of the metal product. However, manual testing is inefficient, and the contact points between the manual positive and negative terminals and the metal product are prone to deviation, resulting in poor consistency of the test results.
[0032] The resistance testing fixture of this application can improve the efficiency of resistance testing of metal products and the consistency of test results.
[0033] To facilitate the reader's understanding of the concept of this utility model, the specific structure of the resistance testing fixture is described below:
[0034] Please see Figure 1The resistance testing fixture 100 includes a base 1, a fixing block 2, a first sliding assembly 3, a second sliding assembly 4, a first probe 5, and a second probe 6.

The first sliding assembly 3 and the second sliding assembly 4 are located on opposite sides of the fixing block 2. The first probe 5 is disposed on the first sliding assembly 3, which assists the first probe 5 in moving relative to the base 1, allowing the first probe 5 to move closer to and away from the fixing block 2. The first probe 5 abuts against one end of the component under test. The second probe 6 is disposed on the second sliding assembly 4, which assists the second probe 6 in moving relative to the base 1, allowing the second probe 6 to move closer to and away from the fixing block 2. The second probe 6 abuts against the other end of the component under test. During the resistance testing of a component under test (DUT), the resistance testing fixture 100 is placed in a resistance testing machine.

The first probe 5 is moved closer to the fixing block 2 until it touches one end of the DUT, and the second probe 6 is moved closer to the fixing block 2 until it touches the other end of the DUT. This allows for a faster resistance test, and the contact points between the first probe 5, the second probe 6, and the DUT are relatively fixed, reducing the likelihood of deviation and resulting in good consistency of the test results.

The first clamping member is provided with a first notch, and the second clamping member is provided with a second notch. The first notch and the second notch are connected. A portion of the first probe abuts against the first notch, and another portion of the first probe abuts against the second notch, so that the first clamping member and the second clamping member clamp the first probe.
5. The resistance testing fixture according to claim 4, characterized in that, One end of the first clamping member is provided with a third notch, a first protrusion, and a second protrusion. The first protrusion and the second protrusion are respectively located on opposite sides of the third notch. The first sliding assembly also includes a first fixing pin. One end of the first fixing pin is fixed to the first protrusion, and the other end of the first fixing pin is fixed to the second protrusion. One end of the second clamping member is provided with a third protrusion. The third protrusion is located in the third notch and is rotatably disposed on the first fixing pin, so that the second clamping member can rotate relative to the first clamping member. The first sliding assembly further includes a first screw connector, one end of which abuts against the other end of the second clamping member, and the other end of the first screw connector is screwed to the other end of the first clamping member.
6. The resistance testing fixture according to claim 1, characterized in that, The second sliding assembly includes a second slide rod and a second slider. The second slide rod is fixed to the base, the second slider is slidably disposed on the second slide rod, and the second probe is disposed on the second slider.
7. The resistance testing fixture according to claim 6, characterized in that, The base is provided with a second groove, the second slide rod is fixed to the second groove, and at least a portion of the second slider is located within the second groove.
8. The resistance testing fixture according to claim 6, characterized in that, The second sliding assembly further includes a third clamping member and a fourth clamping member. The third clamping member is fixed to the second slider, and the fourth clamping member is fixed to the third clamping member. The third clamping member is provided with a fourth notch, and the fourth clamping member is provided with a fifth notch. The fourth notch and the fifth notch are in communication. A portion of the second probe abuts against the fourth notch, and another portion of the second probe abuts against the fifth notch, so that the third clamping member and the fourth clamping member clamp the second probe.
9. The resistance testing fixture according to claim 8, characterized in that, The third clamping member has a sixth notch, a fourth protrusion, and a fifth protrusion at one end.
