Description

Technical Field

[0001] This utility model relates to cable communication testing equipment, specifically a portable continuity and line sequence tester. Background Technology

[0002] With the development of intelligent coal mining, the stability of product quality is becoming increasingly important. Cables serve as the bridge for all electrical connections in intelligent coal mining faces. Ensuring the continuity and accuracy of mine cables, as well as their operational stability, is crucial for ensuring safe and efficient intelligent coal mining. Currently, during testing, workers often use multimeters to check both ends of the cables, which is time-consuming and labor-intensive. Furthermore, incorrect wiring sequence checks are easily made, leading to errors and losses. Therefore, a portable testing device is urgently needed to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide a portable cable continuity and sequence tester to solve the problems mentioned in the background art.

[0004] To address the technical problems mentioned above, this utility model adopts the following technical solution:

[0005] A portable cable continuity and wiring sequence detector includes a transmitter and a feedback end. The transmitter is surrounded by a metal frame, and a battery is installed inside the metal frame. One end of the battery is electrically connected to a pulse signal modulation transmitter. One end of the pulse signal modulation transmitter is equipped with a frequency converter. A switch is electrically connected to one side of the frequency converter. An LED indicator is electrically connected to one end of the switch. A cable connection is installed on the other side of the battery.

[0006] The feedback terminal is surrounded by a metal frame, and a battery is installed inside the metal frame. One end of the battery is electrically connected to a pulse signal modulation feedback device, and one end of the pulse signal modulation feedback device is equipped with a frequency converter. A switch is electrically connected to one side of the frequency converter, and an LED indicator is electrically connected to one end of the switch. A cable is installed on the other side of the battery.

[0007] As a further improvement of this utility model, screws are installed on the outside of the metal frame, and the metal frame is connected to a metal shell by the screws.

[0008] As a further improvement of this utility model, there are 8 LED indicator lights, and the LED lights flash intermittently.

[0009] As a further improvement of this utility model, the cable connector has 4-8 connection ports inside, and the cable connector is plugged into the cable to be tested.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model discloses a portable continuity and wiring sequence tester, designed in two separate parts: a transmitter and a feedback unit. It uses a 9V battery for low power consumption, features a green indicator light, and has a SUS304 stainless steel casing. Its small size makes it easy to operate and carry, and it can test cables of various lengths. Simply connect both ends of the cable to the transmitter and feedback unit of the tester, turn on the power switch on the transmitter, and the transmitter will automatically send pulse signals to test each circuit according to the wiring sequence. When the feedback unit receives a pulse signal from the same wire core, it provides feedback on the cable continuity and wiring sequence test results through flashing lights. A sequential flashing of the lights indicates a correct wiring sequence and no internal open circuit in the cable; intermittent flashing indicates an incorrect wiring sequence; if the number of flashing lights does not match the number of wire cores in the cable, there is an open circuit. The sequence number of the lights that do not light up normally indicates an open circuit. This utility model allows engineers to quickly determine if there are problems with cables through flashing lights, improving work efficiency and reducing errors caused by human operation.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] like Figure 1 As shown in .2.3, a portable cable continuity and sequence detector includes a transmitter and a feedback end. The transmitter is surrounded by a metal frame 7, and a battery 2 is installed inside the metal frame 7. One end of the battery 2 is electrically connected to a pulse signal modulation transmitter 3, and one end of the pulse signal modulation transmitter 3 is equipped with a frequency converter 4. One side of the frequency converter 4 is electrically connected to a switch 5, and one end of the switch 5 is electrically connected to an LED indicator 6. The other side of the battery 2 is equipped with a cable connector 1.

[0021] The feedback end is surrounded by a metal frame 7, and a battery 2 is installed inside the metal frame 7. One end of the battery 2 is electrically connected to a pulse signal modulation feedback device 9, and one end of the pulse signal modulation feedback device 9 is equipped with a frequency converter 4. One side of the frequency converter 4 is electrically connected to a switch 5, and one end of the switch 5 is electrically connected to an LED indicator 6. A cable connection 1 is installed on the other side of the battery 2.

[0022] As a further improvement of this utility model, a screw 8 is installed on the outside of the metal frame 7, and the metal frame is connected to a metal shell through the screw 8.

[0023] As a further improvement of this utility model, the LED indicator 6 has 8 LEDs, and the LED indicator 6 flashes intermittently.

[0024] As a further improvement of this utility model, the cable connector 1 has 4-8 connectors 11 inside, and the cable connector 1 is plugged into the cable 12 to be tested.

[0025] The working principle of this utility model is as follows:

[0026] In use, simply connect both ends of the cable 12 to the transmitter and feedback end of the tester, and turn on the power switches 5 of the transmitter and feedback end. The transmitter will automatically send pulse signals through the pulse signal modulator 3, and test each circuit according to the wiring sequence. When the feedback end receives the pulse signal of the same core, it will feed back to the transmitter through the pulse signal modulator 9. At the same time, the flashing of the LED indicator lights provides feedback on the continuity and wiring sequence test results of the cable 12. If the LED indicator lights flash sequentially, it indicates that the wiring sequence is correct and there is no open circuit inside the test cable 12. If the LED indicator lights flash intermittently, the cable wiring sequence is incorrect. If the number of LED beads flashing in the LED indicator lights does not match the number of cores in the test cable 12, there is an open circuit in the cable. The LED beads in the LED indicator lights that do not light up normally are open circuits.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
