Description

Technical Field

[0001] The present invention relates to the technical field of signal generators, and particularly to a measurement system for a MAG signal generator and a calibration method therefor. Background Art

[0002] A signal generator is a device that can provide electrical signals with various frequencies, waveforms, and output levels. When measuring the amplitude characteristics, frequency characteristics, transmission characteristics, and other electrical parameters of various telecommunication systems or telecommunication devices, as well as when measuring the characteristics and parameters of components, it is used as a test signal source or excitation source. A signal generator is also known as a signal source or oscillator and has a wide range of applications in production practice and the scientific and technological fields. Various waveform curves can be represented by trigonometric function equations. A circuit that can generate multiple waveforms, such as triangular waves, sawtooth waves, rectangular waves (including square waves), and sine waves, is called a function signal generator. Function signal generators have very wide applications in circuit experiments and equipment detection. For example, in communication, broadcasting, and television systems, radio frequency (high-frequency) transmission is required. Here, the radio frequency wave is the carrier wave, and to carry out audio (low-frequency), video signals, or pulse signals, an oscillator capable of generating high frequencies is needed. Before use, a signal generator needs to be connected to a standard device for calibration, and among them, the MAG signal generator is widely used.

[0003] In the existing measurement system of a MAG signal generator, the transmission wires on it will have wear on the surface after long-term use. If the wear is severe and leakage occurs, the measurement accuracy will be reduced. There is a lack of a structure that can eliminate the error caused by the breakage and leakage of the transmission wires. Moreover, during the measurement process, the connection of the plug connectors is prone to looseness, resulting in unstable signal transmission and affecting normal use, and the practicability is poor. Summary of the Invention

Outside the connecting shaft, a spur gear is fixedly sleeved. The right end of the connecting shaft is fixedly connected with a second bevel gear. In the middle of the right side of the receiving box, a plug connector is fixedly arranged. On the upper and lower ends of the right side of the receiving box, a reinforcing connection column mechanism is fixedly arranged. The functional cylinder mechanism includes a functional cylinder. In the middle of the outside of the functional cylinder, a wear-resistant ring is fixedly sleeved. On the right side of the outside of the functional cylinder, a gear ring is fixedly sleeved. On the left side of the outside of the functional cylinder, a lamp ring is fixedly sleeved. On the right side of the inner cavity of the functional cylinder, a spiral sleeve is fixedly arranged. On the inner wall of the spiral sleeve, a number of leakage test beads are evenly fixedly arranged. On the left side of the inner cavity of the functional cylinder, a spiral rod is fixedly arranged. On the inner wall of the spiral rod, a number of flexible fibers are evenly fixedly arranged.

[0006] Preferably, on the right side of the MAG signal generator body and around each transmission wire, four limiting grooves are opened. The left side of the connecting shaft is rotatably connected to the left wall of the inner cavity of the receiving box.

[0007] Preferably, at the four corners of the left side of the receiving box, limiting columns are fixedly arranged. The four limiting columns are adapted to the corresponding limiting grooves. The wear-resistant ring rotatably penetrates through the left wall of the receiving box.

[0008] Preferably, the reinforcing connection column mechanism includes a reinforcing column. The left side of the reinforcing column is fixedly connected to the right wall of the receiving box. On the upper and lower ends of the reinforcing column, placing grooves are opened.

[0009] Preferably, on the left side of each placing groove, a long elastic piece is fixedly arranged. On the right part of the mutually remote sides of the two long elastic pieces, limiting protrusions are fixedly arranged.

[0010] Preferably, a magnetic ring is slidably sleeved on the outside of the reinforcing column. On the left and right sides of the outside of the reinforcing column, magnet rings are fixedly sleeved.

[0011] Preferably, the right end of the transmission wire passes through the spiral rod and the spiral sleeve and is wound around the outside of the reel, and the right end of the transmission wire is connected to the plug connector via a conductive wire.

[0012] Preferably, a plurality of the leakage test beads are electrically connected to the light ring via a wire, and a plurality of the leakage test beads are in contact with an outer wall of the transmission wire.

[0013] The present invention also provides a calibration method for a measurement system of a MAG signal generator, the specific method comprising the following steps:

[0014] Step 1: Hold the container box and pull the limit column out of the limit slot, then hold the crank handle and rotate it, and the shaft and the reel will rotate accordingly. Use the other hand to slowly pull the transmission wire outward to adjust the length of the transmission wire outside the container box. After adjusting to the required length, insert the plug connector into the connection end of the standard device, and insert the reinforcement column into the limit hole on the standard device at the same time;

[0015] Step 2: During the process, when the reinforcement column moves into the limit hole, the magnetic ring will be pushed to the left, so that the right end of the long spring piece is not restricted by the magnetic ring. The long spring piece bends and tilts under the action of its own elasticity, and contacts the inner wall of the limit hole, so that the reinforcement column is stably connected to the limit hole, thereby stably connecting the plug connector to the standard device. After the connection is completed, observe the display screen and operate the adjustment button for calibration;

[0016] Step 3. After the proofreading is completed, hold the containing box and pull it hard to the left to release the plug connector, reinforce the connection between the connecting column mechanism and the standard instrument, then hold the crank handle with your hand and rotate it in the opposite direction, the rotating shaft and the reel will rotate accordingly, and the external transmission wire will be rolled up and wrapped around the outside of the reel. During the process, the first bevel gear rotates driven by the rotating shaft, and the second bevel gear and the spur gear rotate at the same time. Since the spur gear is engaged with the gear ring, it drives the functional cylinder to rotate, and the transmission wire passes through the inside of the functional cylinder. The spiral rod and the flexible fiber rotate to promptly remove the dust adhered to the surface of the transmission wire, and then the transmission wire with a clean surface passes through the spiral sleeve, and the leakage test bead contacts the surface of the transmission wire. When the damaged part on the surface of the transmission wire contacts the leakage test bead, the circuit between the leakage test bead and the light ring will be connected, and the light ring will light up in time to indicate that there is damage and leakage on the surface of the transmission wire.

[0017] Preferably, the front end of the second bevel gear is meshed and connected with the rear end of the first bevel gear, and the front end of the gear ring is meshed and connected with the rear end of the spur gear.

4. A calibration method for a measurement system implementing the MAG signal generator according to claim 3, characterized in that: This method comprises the following steps: Step 1: Hold the accommodation box (61) by hand to pull out the limiting column (613) from the limiting groove (7), then hold the crank (65) by hand to rotate, the rotating shaft (62) and the reel (63) rotate accordingly, and use the other hand to slowly pull out the transmission wire (5) outward to adjust the length of the transmission wire (5) outside the accommodation box (61). After adjusting to the required length, insert the plug connector (611) into the connection end of the standardizer, and at the same time, insert the reinforcement column (6121) into the limiting hole on the standardizer; Step 2: During the process, while the reinforcement column (6121) moves into the limiting hole, the magnetic ring (6125) will be pushed leftward, so that the right end of the long elastic piece (6123) is not restricted by the magnetic ring (6125). The long elastic piece (6123) bends and warps under the action of its own elasticity and contacts the inner wall of the limiting hole, so that the reinforcement column (6121) is stably connected to the limiting hole, thereby enabling the plug connector (611) to be stably connected to the standardizer. After connection, observe the display screen (2) and operate the adjustment button (3) for calibration; Step 3: After the proofreading is completed, hold the accommodation box (61) and pull it hard to the left to release the connection between the plug connector (611), the reinforcement connection column mechanism (612) and the standard device. Then, hold the crank (65) with your hand and rotate it in the reverse direction. The rotating shaft (62) and the reel (63) will rotate accordingly, and the external transmission wire (5) will be wound up and wound around the outside of the reel (63). During this process, the first bevel gear (64) rotates driven by the rotating shaft (62), and the second bevel gear (610) and the spur gear (69) rotate simultaneously. Since the spur gear (69) meshes with the gear ring (663), the function cylinder (661) is driven to rotate.
