Description

Technical Field

[0001] This utility model relates to the field of continuity tester technology, and in particular to a continuity tester for automotive wiring harness testing. Background Technology

[0002] A continuity tester is used to verify that automotive wiring harnesses meet conductivity standards. When using the continuity tester, the automotive wiring harness is connected to the main body of the tester. A certain current is applied to the cable to be tested, and the voltage and current values ​​at the cable endpoints are measured. The tester internally uses Ohm's law to convert these measurements into an accurate resistance value. This resistance value is then compared with the user-defined resistance value to determine whether it meets the user's specifications. The result is displayed on the tester as "pass" or "fail".

[0003] The inventors discovered in their daily work that continuity testers still have at least the following problems: When using a continuity tester, the automotive wiring harness is connected to the main body of the testing device. A certain current is applied to the cable to be tested, and then the voltage and current values ​​at the cable endpoints are measured. The tester internally uses Ohm's law to convert these measurement results to obtain an accurate resistance value. This resistance value is then compared with the resistance value set by the user to determine whether it meets the user's specifications, and the result is displayed on the tester in the form of "pass" or "fail". However, in actual use, because the connecting cable is located on one side of the testing device, it may be dragged during transportation, which to some extent affects the handling and storage of the testing device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a continuity tester for automotive wiring harness testing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a continuity tester for automotive wiring harness testing, comprising a tester body, a display screen on one side of the tester body, an operation panel on one side of the tester body, a connecting wire on one side of the tester body, and a storage device on the top of the tester body, the storage device comprising a connecting rod, the connecting rod being fixedly connected to the top of the tester body, and a rubber cylinder being fixedly connected to the surface of the connecting rod.

[0006] The effect achieved by the above components is that when using the storage device, the connecting wire is simultaneously wrapped around the surface of the connecting rod on the side away from the main body of the tester, which makes it easier to confine the connecting wire to the top of the main body of the tester.

[0007] Preferably, a rotating block is rotatably inserted into the top of the main body of the tester, a first damping rod is fixedly connected to the top of the rotating block, a connecting block is fixedly connected to the top of the first damping rod, a first spring is sleeved on the surface of the first damping rod, one end of the first spring is fixedly connected to the top of the rotating block, the top of the first spring is fixedly connected to the bottom of the connecting block, a sliding frame is provided on one side of the connecting block, and the sliding frame is sleeved on the surface of the rubber cylinder.

[0008] The effect achieved by the above components is as follows: the rotating block is manually controlled to rotate to a suitable position, and then the sliding frame is fitted onto the surface of the connecting rod at the end of the connecting line away from the main body of the tester. Then, the connecting block is pulled towards the top of the main body of the tester by the first spring, which makes it easy to restrict the connecting line to the surface of the connecting rod by the sliding frame.

[0009] Preferably, a second damping rod is fixedly connected to one side of the connecting block, the end of the second damping rod away from the connecting block is fixedly connected to one side of the sliding frame, a second spring is sleeved on the surface of the second damping rod, one end of the second spring is fixedly connected to one side of the connecting block, and the end of the second spring near the sliding frame is fixedly connected to one side of the sliding frame.

[0010] The effect achieved by the above components is that after the sliding frame is fitted onto the surface of the connecting rod, the second spring is stretched, which can effectively fit the sliding frame onto the surface of the connecting rod at various positions.

[0011] Preferably, a rotating rod is rotatably inserted into the top of the connecting block, an extrusion strip is fixedly connected to the bottom of the rotating rod, a rubber sleeve is fixedly connected to the top of the connecting block, the rubber sleeve is fitted onto the surface of the rotating rod, and the top of the rubber sleeve is pressed against the bottom of the extrusion strip.

[0012] The effect achieved by the above components is that the manual control of the extrusion bar drives the rotating rod to rotate, thereby causing the extrusion bar to press against the end of the connecting wire away from the main body of the tester, thus confining the connecting wire to the top of the main body of the tester.

[0013] Preferably, a support device is provided at the bottom of the main body of the tester. The support device includes a support plate. A groove is provided at the bottom of the main body of the tester. A first round rod is fixedly connected to the inner wall of the groove. The support plate is rotatably sleeved on the surface of the first round rod.

[0014] The effect achieved by the above components is that when using the support device, the support plate can be manually rotated on the surface of the first round rod, so that the end of the support plate away from the first round rod is placed on the table, which can effectively support one side of the main body of the tester.

[0015] Preferably, a second round rod is fixedly connected to the inner wall of the end of the support plate away from the first round rod, and a rotating strip is rotatably sleeved on the surface of the second round rod, with a rubber plate fixedly connected to one side of the rotating strip.

[0016] The effect achieved by the above components is that the rotating bar is manually controlled to rotate on the surface of the second round rod, thereby pressing the rubber plate against the tabletop, which can prevent the support plate from sliding on the tabletop to a certain extent.

[0017] Preferably, a limiting groove is formed on one side of the main body of the tester, and an L-shaped plate is slidably connected to the inner wall of the limiting groove. The end of the L-shaped plate away from the limiting groove is located on the side of the support plate away from the groove.

[0018] The effect achieved by the above components is as follows: when the support plate is set on one side of the groove, the end of the L-shaped plate away from the limiting groove is set on the side of the support plate close to the groove, thereby restricting the support plate outside the groove. When the support device is not used, the support plate is set inside the groove, and the end of the L-shaped plate away from the limiting groove is set on the side of the support plate away from the groove, which makes it easier to restrict the support plate inside the groove.

[0019] Preferably, a third damping rod is fixedly connected to one side of the inner wall of the limiting groove. The end of the third damping rod near the L-shaped plate is fixedly connected to one side of the L-shaped plate. A third spring is sleeved on the surface of the third damping rod. One end of the third spring is fixedly connected to one side of the inner wall of the limiting groove, and the end of the third spring near the L-shaped plate is fixedly connected to one side of the L-shaped plate.

[0020] The effect achieved by the above components is that the L-shaped plate is pressed towards the groove by the third spring, so that the end of the L-shaped plate away from the limiting groove can be set at the bottom of the tester body.

[0021] In this invention, by setting up a storage device, when using the storage device, the connecting wire is simultaneously wound around the surface of the connecting rod on the side away from the main body of the tester, which makes it easy to confine the connecting wire to the top of the main body of the tester.

[0027] Example 1, as Figure 1-4 As shown, a continuity tester for automotive wiring harness testing includes a display screen 2 and an operation panel 3 on one side of the main body 1, a connecting cable 4 on one side of the main body 1, and a storage device 5 on the top of the main body 1. When using the continuity tester, the automotive wiring harness is connected to the main body of the tester. A certain current is applied to the cable to be tested, and the voltage and current values ​​at the cable endpoints are measured. The tester internally uses Ohm's law to convert these measurement results to obtain an accurate resistance value. This resistance value is then compared with the resistance value set by the user to determine whether it meets the user's specifications. The result is displayed on the tester as "pass" or "fail".

[0028] Reference Figure 2 and Figure 3The storage device 5 includes a connecting rod 501, which is fixedly connected to the top of the tester body 1. A rubber sleeve 502 is fixedly connected to the surface of the connecting rod 501. When using the storage device 5, the connecting wire 4 is simultaneously wound around the side of the connecting rod 501 away from the tester body 1, which helps to confine the connecting wire 4 to the top of the tester body 1. A rotating block 503 is rotatably inserted into the top of the tester body 1. A first damping rod 504 is fixedly connected to the top of the rotating block 503. A connecting block 506 is fixedly connected to the top of the first damping rod 504. A first spring 505 is fitted onto the top of a rotating block 503, and the top of the first spring 505 is fixedly connected to the bottom of a connecting block 506. A sliding frame 507 is provided on one side of the connecting block 506, and the sliding frame 507 is fitted onto the surface of the rubber cylinder 502. The rotating block 503 is manually rotated to a suitable position, and then the sliding frame 507 is fitted onto the surface of the connecting rod 501 at the end of the connecting line 4 away from the main body 1 of the tester. Then, the connecting block 506 is pulled towards the top of the main body 1 by the first spring 505, which facilitates the movement of the sliding frame 507. 7. The connecting line 4 is constrained on the surface of the connecting rod 501. A second damping rod 508 is fixedly connected to one side of the connecting block 506. The end of the second damping rod 508 away from the connecting block 506 is fixedly connected to one side of the sliding frame 507. A second spring 509 is sleeved on the surface of the second damping rod 508. One end of the second spring 509 is fixedly connected to one side of the connecting block 506, and the end of the second spring 509 near the sliding frame 507 is fixedly connected to one side of the sliding frame 507. After the sliding frame 507 is sleeved on the surface of the connecting rod 501, the second spring 509 is stretched, which can effectively control the sliding frame 501. The moving frame 507 is fitted onto the surface of the connecting rod 501 at various positions. A rotating rod 510 is rotatably inserted into the top of the connecting block 506. An extrusion strip 511 is fixedly connected to the bottom of the rotating rod 510. A rubber sleeve 512 is fixedly connected to the top of the connecting block 506. The rubber sleeve 512 is fitted onto the surface of the rotating rod 510. The top of the rubber sleeve 512 presses against the bottom of the extrusion strip 511. The extrusion strip 511 is manually controlled to drive the rotating rod 510 to rotate, thereby causing the extrusion strip 511 to press against the end of the connecting line 4 away from the main body 1 of the tester. This can restrict the connecting line 4 to the top of the main body 1 of the tester.

[0029] Reference Figure 4The bottom of the tester body 1 is provided with a support device 6, which includes a support plate 603. A groove 601 is formed on the bottom of the tester body 1, and a first round rod 602 is fixedly connected to the inner wall of the groove 601. The support plate 603 is rotatably sleeved on the surface of the first round rod 602. When using the support device 6, the support plate 603 is manually rotated on the surface of the first round rod 602, so that the end of the support plate 603 away from the first round rod 602 is placed on the table. This can effectively support one side of the tester body 1. A second round rod 608 is fixedly connected to the inner wall of one end of the 02. A rotating strip 609 is rotatably sleeved on the surface of the second round rod 608. A rubber plate 610 is fixedly connected to one side of the rotating strip 609. The rotating strip 609 is manually controlled to rotate on the surface of the second round rod 608, thereby pressing the rubber plate 610 against the table, which can prevent the support plate 603 from sliding on the table to a certain extent. A limiting groove 604 is opened on one side of the main body 1 of the testing instrument. An L-shaped plate 607 is slidably connected to the inner wall of the limiting groove 604. The end of the L-shaped plate 607 away from the limiting groove 604 is set on the support plate 603. 3. On the side away from the groove 601, when the support plate 603 is placed on one side of the groove 601, the end of the L-shaped plate 607 away from the limiting groove 604 is placed on the side of the support plate 603 close to the groove 601, thus restricting the support plate 603 outside the groove 601. When the support device 6 is not used, the support plate 603 is placed inside the groove 601, and the end of the L-shaped plate 607 away from the limiting groove 604 is placed on the side of the support plate 603 away from the groove 601. This facilitates restricting the support plate 603 inside the groove 601, and the side of the inner wall of the limiting groove 604. A third damping rod 605 is fixedly connected. One end of the third damping rod 605 near the L-shaped plate 607 is fixedly connected to one side of the L-shaped plate 607. A third spring 606 is sleeved on the surface of the third damping rod 605. One end of the third spring 606 is fixedly connected to one side of the inner wall of the limiting groove 604. The end of the third spring 606 near the L-shaped plate 607 is fixedly connected to one side of the L-shaped plate 607. By pressing the L-shaped plate 607 towards the groove 601 through the third spring 606, the end of the L-shaped plate 607 away from the limiting groove 604 can be set at the bottom of the main body 1 of the testing instrument.

[0030] Working principle: When using the continuity tester, the automotive wiring harness is connected to the main body of the testing device. A certain current is applied to the cable to be tested, and then the voltage and current values ​​at the cable endpoints are measured. The tester internally uses Ohm's law to convert these measurement results to obtain an accurate resistance value. This resistance value is then compared with the resistance value set by the user to determine whether it meets the user's specifications. The result is displayed on the tester as "pass" or "fail". When using the storage device 5, the connecting wire 4 is simultaneously wound around the surface of the connecting rod 501 on the side away from the main body 1 of the tester. The rotating block 503 is manually controlled to rotate to the appropriate position, thereby placing the sliding frame 507 on the surface of the connecting rod 501 at the end of the connecting wire 4 away from the main body 1 of the tester. Then, through the first spring 50... 5. Pull the connecting block 506 towards the top of the tester body 1. This facilitates the restriction of the connecting wire 4 to the surface of the connecting rod 501 via the sliding frame 507. Manually control the extrusion bar 511 to drive the rotating rod 510 to rotate, thereby causing the extrusion bar 511 to press against the end of the connecting wire 4 away from the tester body 1. This restricts the connecting wire 4 to the top of the tester body 1. After the sliding frame 507 is fitted onto the surface of the connecting rod 501, the second spring 509 is stretched, which effectively fits the sliding frame 507 onto the surface of the connecting rod 501. When using the support device 6, the surface of the connecting rod 501 at each position is supported by manually rotating the support plate 603 on the surface of the first round rod 602. This causes the end of the support plate 603 away from the first round rod 602 to be placed on the table. The rotating bar 609 is also manually rotated on the surface of the second round rod 608, causing the rubber plate 610 to be pressed against the table. This helps to prevent the support plate 603 from sliding on the table to a certain extent, thus effectively supporting one side of the tester body 1. When the support plate 603 is placed on one side of the groove 601, the L-shaped plate 607 is moved away from the limiting groove 60. One end of the support plate 603 is positioned on the side of the support plate 603 near the groove 601, thereby restricting the support plate 603 outside the groove 601. When the support device 6 is not used, the support plate 603 is positioned inside the groove 601. The end of the L-shaped plate 607 away from the limiting groove 604 is positioned on the side of the support plate 603 away from the groove 601, which facilitates restricting the support plate 603 inside the groove 601. The L-shaped plate 607 is pressed towards the groove 601 by the third spring 606, so that the end of the L-shaped plate 607 away from the limiting groove 604 can be positioned at the bottom of the tester body 1.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process. The continuity tester mentioned in this case is model TH2882A-3.
