Description

Technical Field

[0001] This utility model relates to the field of resistor testing technology, specifically to a resistor electrical testing device. Background Technology

[0002] With the development of science and technology and the progress of the times, resistors are usually simply called resistors. After a resistor is connected to a circuit, its resistance value is fixed. It basically consists of two leads and can limit the current through the branch it is connected to. After the resistor is manufactured, it needs to be tested by a testing instrument to check whether the resistance value is correct. Therefore, a resistor electrical testing device is needed to test the resistance value of the resistor.

[0003] A search revealed a Chinese patent publication number (CN 215813075 U) disclosing a testing device for resistor production. The device includes a fixed backplate, with a clamping frame body mounted externally at the front end of the backplate. A test meter body is clamped internally at the front end of the clamping frame body, and test pens are connected to both external ends of the test meter body. Extending crossbars are installed on both sides of the lower outer wall of the clamping frame body, with a central upright plate mounted at the outer end of each crossbar. The crossbars are telescopic columns. A fixed top plate and a fixed bottom plate are respectively installed on the upper and lower sides of the central upright plate. A pneumatic telescopic push rod is installed through the interior of both the top and bottom plates. An extended bottom plate is connected to the bottom end of each pneumatic telescopic push rod, and a positioning collar is installed on the side of the extended bottom plate, with a test pen fitted inside the positioning collar. This resistor production testing device eliminates the need for users to repeatedly remove and place the test meter pens during resistor testing, improving resistance testing efficiency.

[0004] The resistor testing equipment in the aforementioned patent still has some shortcomings. Most existing resistor electrical testing equipment requires workers to hold the wires and connect them to the multimeter head for testing. However, this method makes it difficult to stably connect the leads to the two ends of the resistor. Poor contact can easily occur due to worker errors, resulting in inaccurate test data. Furthermore, it is even more difficult to apply when resistors need to be tested in batches. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a resistor electrical testing device. It solves the problem that most existing resistor electrical testing devices rely on workers manually connecting the leads to the multimeter head. However, this method makes it difficult to stably connect the leads to the two ends of the resistor, and poor contact can easily occur due to worker errors, leading to inaccurate test data. Furthermore, this method is even less suitable when resistors need to be tested in batches.

[0006] This utility model provides the following technical solution: a resistor electrical testing device, including a support base, a mounting groove is provided at the top of the support base, a multimeter is provided in the mounting groove, two power leads are provided on the multimeter, a resistor testing auxiliary component is provided at the top of the support base, and a resistor body is provided on the resistor testing auxiliary component.

[0007] The resistor detection auxiliary component includes a bottom support block disposed at the top of the support base. A resistor placement slot is formed at the top of the bottom support block, and the resistor body is disposed within the resistor placement slot. A side connecting frame is provided on the side of the top of the bottom support block, and a contact connecting rod is inserted through the side connecting frame. A contact spring is fitted on the top of the contact connecting rod, with one end connected to the contact connecting rod and the other end connected to the side connecting frame. A resistor contact plate is rotatably connected to the bottom of the contact connecting rod. Two symmetrical side rotating slots are formed at the top of the support base, and a drive screw is rotatably inserted into each side rotating slot. A connecting block is inserted into each side rotating slot, with the drive screw threaded through the bottom of the connecting block. A resistor head contact sleeve is provided at the top of the connecting block, and a side insertion hole is formed on the side of the resistor head contact sleeve, into which a conductive rod is inserted.

[0008] Preferred technical solution 1: The end of the conductive rod passes through the side insertion hole, and the conductive rod is provided with a lead wire connection hole.

[0009] Preferred technical solution 2: A fixing screw hole is provided on the side wall of the lead wire connection hole, and a fixing screw is rotatably inserted into the fixing screw hole.

[0010] Preferred technical solution 3: A baffle is provided at the top of the abutting connecting rod.

[0011] This solution enables the abutment spring fitted on the abutment connecting rod to be blocked.

[0012] Preferred technical solution four: The bottom end of the resistor contact plate is arc-shaped, and the bottom end of the resistor contact plate abuts against the top surface of the resistor body.

[0013] This solution makes the contact between the resistor contact plate and the resistor body more stable.

[0014] Preferred technical solution five: The longitudinal section of both the connecting plug and the driving screw is rectangular.

[0015] This design ensures that the connecting block is limited in its sliding position within the side rotating groove, preventing it from rotating with the drive screw.

[0016] Compared with the prior art, the present invention provides a resistor electrical property testing device, which has the following advantages:

[0017] (1) This utility model provides a multimeter and a resistor testing auxiliary component on a support base. The resistor placement slot in the resistor testing auxiliary component, together with the resistor contact plate, can limit and fix the resistor body. The two ends of the resistor body can be driven by the rotation of the drive screw, so that the drive screw drives the resistor head contact sleeve and conductive rod to contact the end of the resistor body. The user then inserts the power lead connected to the multimeter into the lead connection hole, thereby electrically connecting the multimeter and the resistor body. This makes it convenient for the user to perform resistance testing on the resistor body using the multimeter. This device makes it more convenient to limit and fix the resistor body, and the connection of the multimeter is more stable. This makes it easier for the user to perform batch testing on the resistor body, and the test data is more accurate and convenient for the user to use. Attached Figure Description

[0024] Please see Figure 1-4 ,

[0025] Example 1: A resistor electrical testing device includes a support base 1, a mounting groove 2 at the top of the support base 1, a multimeter 3 in the mounting groove 2, two power leads 4 on the multimeter 3, a resistor testing auxiliary component 5 at the top of the support base 1, and a resistor body 6 on the resistor testing auxiliary component 5.

[0026] The resistor detection auxiliary component 5 includes a bottom support block 501 set at the top of the support base 1. A resistor placement groove 502 is opened at the top of the bottom support block 501. The resistor body 6 is placed in the resistor placement groove 502. A side connecting frame 503 is set on the side of the top of the bottom support block 501. A contact connecting rod 504 is inserted through the side connecting frame 503. A contact spring 505 is sleeved on the top of the contact connecting rod 504. One end of the contact spring 505 is connected to the contact connecting rod 504. The other end of the contact spring 505 is connected to the side connecting frame 503. A resistor contact plate 506 is rotatably connected to the bottom end of the contact connecting rod 504.

[0027] The top of the support base 1 has two symmetrical side rotation slots 507. A drive screw 508 is rotatably inserted into the side rotation slot 507. A connecting block 509 is inserted into the side rotation slot 507. The drive screw 508 is threaded through the bottom of the connecting block 509. A resistor head contact sleeve 510 is provided at the top of the connecting block 509. A side insertion hole 511 is provided on the side of the resistor head contact sleeve 510. A conductive rod 512 is inserted into the side insertion hole 511. The end of the conductive rod 512 passes through the side insertion hole 511. A lead wire connection hole 513 is provided on the conductive rod 512. A fixing screw hole 514 is provided on the side wall of the lead wire connection hole 513. A fixing screw 515 is rotatably inserted into the fixing screw hole 514.

[0028] Example 2: The difference between this example and Example 1 is that a baffle is provided at the top of the connecting rod 504.

[0029] This causes the abutment spring 505, which is sleeved on the abutment connecting rod 504, to be blocked.

[0030] Example 3: The difference between this example and Example 1 is that the bottom end of the resistor contact plate 506 is arc-shaped, and the bottom end of the resistor contact plate 506 abuts against the top surface of the resistor body 6.

[0031] This makes the contact between the resistor contact plate 506 and the resistor body 6 more stable.

[0032] Example 4: The difference between this example and Example 1 is that the longitudinal sections of both the connecting plug 509 and the driving screw 508 are rectangular.

[0033] This limits the sliding of the connecting plug 509 within the side rotating groove 507, preventing it from rotating with the rotation of the drive screw 508.

[0034] In this embodiment, since most existing resistor electrical testing equipment involves workers manually connecting the lead wires to the multimeter head for testing, this method makes it difficult to stably connect the leads to the two ends of the resistor. Poor contact can easily occur due to worker error, resulting in inaccurate test data. Furthermore, this method is even more unsuitable when resistors need to be tested in batches.

[0035] In summary, during specific implementation, when the user needs to perform electrical testing on the resistor body 6, the multimeter 3 uses the Fluke 1 side rotating slot 507 model. The user can first place the resistor body 6 in the resistor placement slot 502 in the resistor testing auxiliary component 5. The side connecting bracket 503 is equipped with an abutment connecting rod 504, and an abutment spring 505 is sleeved on the abutment connecting rod 504. Under the rebound force of the abutment spring 505, the abutment connecting rod 504 can push the resistor abutment plate 506 to abut against the top of the resistor body 6, ensuring the stability of the resistor body 6 in the resistor placement slot 502.

[0036] At this time, by rotating the drive screw 508, which is rotatably set in the side rotation groove 507, the drive screw 508 drives the connecting plug 509 to move closer to the end of the resistor body 6, thereby driving the conductive rod 512 in the resistor head contact sleeve 510 to move closer to the end of the resistor body 6, so that the metal wire at the end of the resistor body 6 is inserted into the resistor head contact sleeve 510 and comes into contact with the end of the conductive rod 512 inserted in the resistor head contact sleeve 510.

[0037] Finally, the user can remove the multimeter 3 from the mounting groove 2 and insert the ends of the two connecting leads 4 connected to the multimeter 3 into the lead connection holes 513 respectively. By rotating the fixing screw 515, the ends of the connecting leads 4 are firmly inserted into the lead connection holes 513. Through the conductive rod 512 and the end of the resistor body 6, the multimeter 3 can more stably detect the resistance of the resistor body 6. Moreover, this device makes it more convenient to limit and fix the resistor body 6 and the connection of the multimeter 3 is more stable. This makes it easier for users to conduct batch testing of the resistor body 6, and the test data is more accurate and convenient for users to use.
