Description

Technical Field

[0001] This utility model belongs to the field of conference machine testing technology, and in particular relates to a conference machine cable testing device. Background Technology

[0002] To quickly achieve the goal of rapidly clamping and positioning the cable, a manually operated quick clamp is more advantageous than a telescopic cylinder, offering both ease of operation and enhanced safety. However, the quick clamp's stroke is fixed, requiring adjustment of its installation height via a bolt through a long, round hole. Furthermore, the quick clamp can still experience downward displacement during use, necessitating adjustment and maintenance, which can be inconvenient. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a conference machine cable testing device that uses a pressure bar with an elastic structure to compensate for the accuracy of the quick clamp stroke.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a conference machine cable testing device, comprising a test platform, a vertical plate, a first guide rod, a quick clamp, a pressure plate, a carrier plate, test probes, a pressure rod, and a spring. The upright plate is fixedly installed on the test bench, the quick clamp is fixedly installed on the upright plate, and positioning blocks are fixedly installed on the left and right sides of the upright plate. The upper and lower ends of the first guide rod are fixedly connected to the positioning blocks and the test bench, respectively. The pressure plate is slidably installed on the first guide rod, and the pressure plate is fixedly connected to the quick clamp pressure head. The test stand is also fixedly equipped with an elastic positioning pin, a second guide sleeve, and a test probe. The bottom surface of the carrier plate is fixedly connected to the upper end of the elastic positioning pin, and a second guide rod is also fixedly installed on the bottom surface of the carrier plate. The second guide rod is slidably installed in the second guide sleeve. The pressure rod is slidably installed inside the pressure plate. A first limiting ring and a second limiting ring are fixedly sleeved on the pressure rod. The first limiting ring and the second limiting ring are located at the upper and lower parts of the pressure plate, respectively. A spring is sleeved on the pressure rod, and the upper and lower ends of the spring act on the pressure plate and the second limiting ring, respectively. The top surface of the carrier plate has a positioning groove, and a through hole that mates with the test probe is provided in the positioning groove. The pressure rod is located directly above the positioning groove.

[0005] Preferably, a rubber head is screwed onto the bottom of the pressure rod.

[0006] Preferably, the upright plate is provided with a waist-shaped hole in the vertical direction, and the quick-clamp screw is used to fix the device in the waist-shaped hole of the upright plate.

[0007] Preferably, a first guide sleeve is fixedly installed on the pressure plate, and the pressure plate is slidably mounted on the first guide rod through the first guide sleeve.

[0008] Compared with the prior art, the advantages of this utility model are: Even after the carrier plate and pressure bar are pressed to their limit positions, the pressure plate can still compress the spring and continue to move downwards until the quick clamp is pressed to its limit position. Therefore, it can reduce the requirements for the stroke and installation position accuracy of the quick clamp. Through the elastic force of the spring, it can ensure that the pressure bar presses and positions the cable tightly.

[0009] The elastic positioning pin pushes the carrier board upward, and at this time the contacts of the ribbon cable are not in contact with the test probe, thus avoiding scratches on the circuit or contact surface of the test probe and the ribbon cable during non-testing processes.

[0013] Figure 3 yes Figure 1 Enlarged structural diagram at point M. Detailed Implementation

[0014] The present invention will now be described in detail with reference to specific embodiments: like Figures 1 to 3 The conference machine cable testing device shown includes a test platform 1, a vertical plate 2, a first guide rod 22, a quick clamp 3, a pressure plate 4, a carrier plate 5, a test probe 8, a pressure rod 9, and a spring 92. The upright plate 2 is vertically fixed on the test bench 1, the quick clamp 3 is fixedly fixed on the upright plate 2, and the positioning blocks 21 are fixedly installed on the left and right sides of the upright plate 2. The upper and lower ends of the first guide rod 22 are fixedly connected to the positioning blocks 21 and the test bench 1 respectively. The pressure plate 4 is slidably sleeved on the first guide rod 22, and the pressure plate 4 is fixedly connected to the pressure head of the quick clamp 3. The test bench 1 is also fixedly installed with an elastic positioning pin 71, a second guide sleeve 72, and a test probe 8. The bottom surface of the carrier plate 5 is fixedly connected to the upper end of the elastic positioning pin 71. A second guide rod 7 is also fixedly installed on the bottom surface of the carrier plate 5. The second guide rod 7 is slidably installed in the second guide sleeve 72. The pressure rod 9 is slidably installed inside the pressure plate 4. A first limiting ring 93 and a second limiting ring 94 are fixedly sleeved on the pressure rod 9. The first limiting ring 93 and the second limiting ring 94 are located at the upper and lower parts of the pressure plate 4, respectively. A spring 92 is sleeved on the pressure rod 9. The upper and lower ends of the spring 92 act on the pressure plate 4 and the second limiting ring 94, respectively. The top surface of the carrier plate 5 has a positioning groove, and a through hole that mates with the test probe 8 is provided in the positioning groove. The pressure rod 9 is located directly above the positioning groove.

[0015] A rubber head 91 is screwed to the bottom of the pressure rod 9. The rubber head 91 has a soft structure, which can prevent the cable 10 from being crushed or scratched.

[0016] The upright plate 2 is provided with a waist-shaped hole 211 in the vertical direction. The quick clamp 3 is screwed and fixedly installed in the waist-shaped hole 211 of the upright plate 2. The installation height of the quick clamp 3 can be adjusted by the waist-shaped hole 211 and the bolt, thereby adjusting the downward stroke of the pressure head of the quick clamp 3.

[0017] A first guide sleeve 41 is fixedly installed on the pressure plate 4. The pressure plate 4 is slidably mounted on the first guide rod 22 through the first guide sleeve 41. The pressure plate 4 is thin and has poor guiding performance. The first guide sleeve 41 can improve the straightness of the pressure plate 4 when it moves up and down.

[0018] During testing, the quick clamp 3 is lifted, causing the combination of pressure plate 4 and pressure rod 9 to move upward along the first guide rod 22. The ribbon cable 10 is placed in the positioning groove of the carrier plate 5. Under the action of the elastic positioning pin 71, the carrier plate 5 is pushed upward. At this time, the contact of the ribbon cable 10 is not in contact with the test probe 8. The quick clamp 3 is pressed down, and its pressure head pushes the combination of pressure plate 4 and pressure rod 9 downward. After the rubber head 91 at the bottom of the pressure rod 9 contacts the ribbon cable 10 on the carrier plate 5, it pushes the combination of carrier plate 5 and second guide rod 7 to compress the elastic positioning pin 71 and move downward along the second guide sleeve 72 until the carrier plate 5 contacts and is positioned with the second guide sleeve 72. At this time, the pressure head of the quick clamp 3 continues to push the combination of pressure plate 4 and pressure rod 9 downward. Since the rubber head 91 has already contacted the ribbon cable 10 and cannot move, the pressure plate 4 compresses the spring 92 and continues to move downward until the quick clamp 3 is pressed down to the limit position. The ribbon cable 10 is then functionally tested through the test probe 8.
