A coaxial cable performance detection method

Abstract

This invention discloses a method for testing the performance of coaxial cables. In use, first loosen the fixing nut, adjust the four sets of clamps, pass the cable body through the sleeve, and then fix it using the clamps. Next, tighten the fixing nut. When torsional strength testing is required, the first motor drives the two sets of sleeves to rotate in opposite directions. Under the action of the clamps, the two sections of the cable body rotate in opposite directions, thus testing the cable body's torsional resistance. When testing the cable body's tensile strength and resistance to frequent bending, first loosen the fixing knob, push the bearing plate downwards, causing it to slide downwards on the surface of the limiting rod. The limiting rod ensures the stability of the entire structure during adjustment. After adjustment, tighten the fixing knob. The second motor then lowers the fixing plate, pressing down on the cable body through the compression rod to test its tensile strength and resistance to frequent bending.

Description

Technical Field

[0001] This invention relates to the field of coaxial cable testing technology, specifically a method for testing the performance of coaxial cables. Background Technology

[0002] Coaxial cable is a type of cable consisting of an inner conductor surrounded by a conductive shield, and two separate dielectric materials (insulating materials). Many coaxial cables also have a protective jacket or sheath. The term "coaxial" refers to the shared geometric axis of the inner conductor and the outer shield. Coaxial cable is a transmission line used to transmit low-loss, high-frequency electrical signals. It is used in telephone trunks, broadband internet cables, high-speed computer data buses, cable television signals, and applications connecting radio transmitters and receivers to antennas. It differs from other shielded cables in that the dimensions of the cable and connectors are controlled to provide precise, constant conductor spacing, which is necessary for its effective use as a transmission line for radio frequency signals. Its applications include feeders connecting radio transmitters and receivers to antennas, computer network (e.g., Ethernet) connections, digital audio (S / PDIF), and distribution of cable television signals. One advantage of coaxial cable over other types of radio transmission lines is that, in an ideal coaxial cable, the electromagnetic field carrying the signal exists only in the space between the inner and outer conductors. This allows coaxial cable to be routed next to metal objects without the power loss seen in other types of transmission lines. Coaxial cables can also protect signals from external electromagnetic interference.

[0003] Before leaving the factory, coaxial cables need to undergo physical performance testing, including tensile strength, bending strength, and resistance to torsion. However, these three performance tests require three different devices, which is inefficient and impractical due to the need to frequently change equipment. Therefore, a coaxial cable performance testing method is needed that can perform all three performance tests without the hassle of frequently changing testing equipment. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a method for testing the performance of a coaxial cable, which employs a coaxial cable testing device. The coaxial cable testing device includes a base, on the top of which is a mounting frame. The base is a hollow shell, and a first motor is installed inside it. A first driving rod is installed at the power output end of the first motor. A first driven rod is rotatably installed inside the base and on top of the first motor. Pulleys are installed on the surfaces of both the first driving rod and the first driven rod, and the two sets of pulleys are connected by a belt drive. A power wheel is installed on the surface of the first driven rod. A second driving rod is provided inside the base and at the left end of the first driving rod.

[0005] Preferably, a first gear is installed at the middle position of the surface of the second driving rod, a rotating rod is provided inside the base and above the second driving rod, and a second gear is installed on the surface of the rotating rod. A second driven rod is installed inside the base and at the top of the rotating rod, and a third gear is installed at the middle position of the surface of the second driven rod. The first gear, the second gear, and the third gear mesh sequentially. A fixing frame is installed on the inner surface of the mounting bracket, and a sleeve is rotatably installed inside the fixing frame. A mounting plate is installed at the end of the sleeve, and a drive wheel is installed on the side surface of the sleeve opposite to the mounting plate.

[0006] Preferably, the mounting plate has an adjusting screw inside, and a fixing nut is threaded onto the surface of the adjusting screw on the left side of the mounting plate. An adjusting block is installed at the other end of the adjusting screw, and a clip is installed on the surface of the adjusting block. A cable body is installed inside the clip. Two sets of sliding rods are symmetrically installed on the top of the mounting frame, and a bearing plate is slidably installed on the surface of the sliding rods. Two sets of fixing knobs are symmetrically arranged on the front of the bearing plate.

[0007] In use, first loosen the fixing nut, adjust the four sets of clamps, pass the cable body through the sleeve, and then use the clamps to fix it. Then tighten the fixing nut. When torsion test is required, the first motor drives the two sets of sleeves to rotate in opposite directions. At this time, under the action of clamp tightening, the two sections of the cable body rotate in opposite directions, thereby testing the torsion resistance of the cable body. When testing the tensile strength and resistance to frequent bending of the cable body, first loosen the fixing knob and push the bearing plate down, so that it drives the fixing plate to slide down on the surface of the limit rod. The function of the limit rod is to ensure the stability of the entire structure during the adjustment process. After the adjustment is completed, tighten the fixing knob. Under the action of the second motor, the fixing plate is driven down, and the cable body is pressed down by the extrusion rod to test its tensile strength and resistance to frequent bending.

[0008] Preferably, a support frame is mounted on the top surface of the bearing plate, a second motor is mounted on the back of the support frame, an eccentric wheel is mounted on the power output end of the second motor, a connecting rod is hinged to the surface of the eccentric wheel, a fixing plate is hinged to the bottom end of the connecting rod, a limit rod is mounted on the inner surface of the mounting frame, and a pressing rod is mounted on the bottom surface of the fixing plate.

[0009] Preferably, the base has a partition installed inside, and the first driving rod and the second driving rod are connected as a whole through the partition. One end of the first driven rod is rotatably installed on the inner wall of the base, and the other end is rotatably installed on the surface of the partition.

[0010] Preferably, a drive wheel is installed on the left side of the surface of the second driven rod, and the drive wheel on the surface of the second driven rod and the drive wheel on the surface of the sleeve are connected by a transmission belt.

[0011] Preferably, the fixing frame is equipped with a bearing that matches the sleeve, and the sleeve is rotatably mounted inside the fixing frame via the bearing.

[0012] Preferably, the mounting plate has two sets of rectangular slots adapted to the adjusting screws inside, and each set of rectangular slots is provided with an adjusting screw. The adjusting screws extend through the mounting plate to the outside, and the adjusting block is installed at the end of the extension section.

[0013] Preferably, the adjusting block has a movable groove inside, and two sets of actuating rods are provided inside the movable groove. The actuating rods pass through the adjusting block, and the clamps are installed at the ends of the adjusting block.

[0014] Preferably, the power output end of the second motor is equipped with a round rod, which passes through the support frame and extends to the front of the support frame, and an eccentric wheel is installed on the surface of the extended section.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. This invention improves upon commonly used testing equipment, allowing the device to operate by first loosening the fixing nut, adjusting the clamp, passing the cable through the sleeve, securing it with the clamp, and then tightening the fixing nut. When torsional strength testing is required, a first motor drives two sets of sleeves to rotate in opposite directions. Under the clamping action, the two sections of the cable body rotate in opposite directions, thus testing the cable's torsional resistance. When testing the cable's tensile strength and frequent bending resistance, a second motor drives an eccentric wheel to rotate. The eccentric wheel causes the compression rod to descend, pressing down on the cable body. This tests both the cable's tensile strength and its ability to withstand frequent bending. Furthermore, the device has a simple structure and is easy to operate.

[0017] 2. This invention, through its clamp and its adjustment and locking structure, allows for the loosening of the fixing nut during use. The clamp's position can be adjusted longitudinally by adjusting the screw, and laterally by adjusting the lever. After adjustment, the fixing nut is tightened. This not only securely clamps the cable but also allows for adjustment according to different cable specifications, ensuring the accuracy of the test data. It also greatly increases the applicability of the device, making it highly practical and possessing broad development potential and significant promotional value.

[0018] 3. This invention, through the setting of a sliding rod, a bearing plate, and a fixing knob, allows the fixing knob to be loosened during use, and the bearing plate to be pushed down, causing the fixing plate to slide downward on the surface of the limiting rod. The function of the limiting rod is to ensure the stability of the entire structure during the adjustment process. After the adjustment is completed, the fixing knob is tightened. Under the action of the second motor, the fixing plate is driven to descend, and the cable body is pressed down by the extrusion rod to test its tensile strength and resistance to frequent bending.
