Description

Technical Field

[0001] This invention relates to the field of waveguide switch performance testing technology, and in particular to a portable waveguide switch electrical continuity testing device and testing method. Background Technology

[0002] Waveguide switches are among the products manufactured and reworked. When assembling and testing the electrical performance of waveguide switches, a DC regulated power supply is needed to energize the motor on top of the switch, causing it to rotate forward and backward. This switches the signal propagation channels and controls the connection and disconnection of corresponding signals. However, in actual assembly and testing, due to the unique electrical connectors of the motors, three different types of motors with different electrical interfaces have been energized using a DC regulated power supply and two wires for a long time, without a corresponding energizing device.

[0003] How to quickly detect the forward and reverse rotation of waveguide switch motors and the continuity of electrical signals for waveguide switches with three different electrical interfaces JY27467T09B98S / JY27467T09B98P / JY27469Y11B98PN (hereinafter referred to as S-type, P-type, and PN-type electrical interfaces) in production sites and laboratory environments is a technical problem that urgently needs to be solved.

[0004] Currently, S-type and P-type electrical interfaces only require motor forward and reverse rotation, without testing electrical continuity. PN-type electrical interfaces, however, require not only motor forward and reverse rotation but also continuity testing of the corresponding path signal by switching the motor direction using a multimeter. This process relies on a DC regulated power supply and two wires. If rapid motor reversal is needed, the wiring sequence of these two wires must be adjusted multiple times, significantly reducing assembly and testing efficiency. If the DC regulated power supply and the two wires are not on-site, it severely impacts the assembly and testing process, and operations can only be performed near the power supply.

[0005] Therefore, current waveguide switch performance testing solutions rely on DC regulated power supplies and operate through two wires, which is not very safe. Furthermore, they need to adapt to various waveguide switch motor electrical interfaces and different states in the production process, which is not very versatile. In addition, testing the continuity of the circuit requires the use of a multimeter, which is not very convenient. Summary of the Invention

[0006] The purpose of this invention is to provide a portable waveguide switch electrical continuity testing device and method, which aims to solve the problems of safety, versatility and convenience in the assembly and testing of waveguide switch electrical performance indicators.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: On one hand, the present invention provides a portable waveguide switch electrical continuity test device, characterized in that it includes: a battery, a power switch, a power module, a toggle switch, a connector, an adapter cable, and a buzzer circuit; The battery is connected to the power module via a power switch and is used to provide power to the device; The power module is used to adjust the battery voltage to the rated operating voltage of the waveguide switch and adjust the battery current to the rated operating current of the waveguide switch. The toggle switch is used to control the forward / reverse detection and buzzer detection of different types of waveguide switches; The connector is used to match different models of waveguide switches; The adapter cable is used as an extension line for a PN waveguide switch; The buzzer circuit is used in conjunction with the corresponding toggle switch to detect the continuity of the circuit.

[0008] In some embodiments, the battery is a lithium battery with a voltage of 12V and a rated capacity of 18mAh; The battery is equipped with a battery charging port.

[0009] In some embodiments, the power module is a DC-DC adjustable DC regulated power module with a voltage adjustment range of 0.5~30V, a current adjustment range of 0~5A, and a maximum power of 35W.

[0010] In some embodiments, the toggle switches are all dual-position toggle switches; The toggle switch includes a first toggle switch, a second toggle switch, and a third toggle switch.

[0011] In some embodiments, the connector includes an S-type female connector, a P-type male connector, and a DB9 female connector; One end of the adapter cable is a DB9 male connector for connecting to a DB9 female connector, and the other end is a PN female connector for connecting to a PN waveguide switch.

[0012] In some embodiments, the buzzer circuit is used in conjunction with a third toggle switch to detect the continuity of the circuit. Before the buzzer circuit is used in conjunction with the third toggle switch for internal circuit continuity detection, it also includes: using a 7805 Zener diode to replace the rated voltage with the 5V buzzer operating voltage.

[0013] In some embodiments, the main body of the device is a metal box with a handle on the top. The device measures 160mm in length, 143mm in width, and 140mm in height, and weighs 3.5kg. The device is also equipped with a counterweight.

[0014] On the other hand, the present invention also provides a portable waveguide switch electrical continuity test method, applied to the aforementioned portable waveguide switch electrical continuity test device, comprising the following steps: Turn on the power supply to power on the device; Adjust the voltage and current on the power module to the operating range of the corresponding waveguide switch model; Connect the PN type waveguide switch to the DB9 female connector via an adapter cable, or connect the P type waveguide switch directly to the P type male connector, or connect the S type waveguide switch directly to the S type female connector. For PN type waveguide switches, toggle the first toggle switch to change the forward and reverse rotation of the motor, and toggle the second toggle switch to check the continuity of the internal circuit of the waveguide switch. If the buzzer sounds when the motor rotates forward or reverse, it means that the motor performance in the corresponding direction of the waveguide switch is qualified. For P-type or S-type waveguide switches, toggle the third toggle switch to change the forward and reverse rotation of the motor. If the motor immediately rotates when the third toggle switch is toggleed continuously, it indicates that the corresponding waveguide switch motor is of qualified performance. Power off the device and remove the adapter cable or corresponding connector.

[0015] The beneficial effects of this invention are: this invention enables waveguide switches of different models to be free from dependence on instruments such as DC power supplies during the testing process, and can improve the safety, versatility and convenience of the testing process.
