Description

Technical Field

[0001] This utility model relates to a testing device for the connection line of a microphone and receiver, belonging to the technical field of testing equipment. Background Technology

[0002] Currently, shipboard internal communication systems are installed in all main compartments, but not all compartments are equipped with the main communication equipment. This results in crew members being unable to conduct internal voice communication in some compartments, or experiencing limitations due to insufficient length of the transceiver cable. A common solution to this problem is to modify and extend the transceiver cable.

[0003] Due to the lack of onboard facilities for modification work, operators typically bring the transceivers to be modified back to the control room. However, some control rooms lack prototype shipboard internal communication equipment, making it impossible to connect the modified transceivers to the main unit for testing. This necessitates bringing them back to the ship for testing, posing varying degrees of safety risks to the shipboard main unit. Furthermore, if an incorrect connection is detected, the transceivers must be brought back to the control room for modification again, significantly reducing the efficiency of modification and maintenance. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a testing device for the connection lines of transmitters and receivers, so that the connection lines of transmitters and receivers after the operation room has been modified can be tested at any time, which effectively improves the efficiency of the modification and maintenance of the connection lines of transmitters and receivers.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A device for testing the connection line of a transmitter and receiver includes a power supply body, an aviation socket, an indicator, and a limit switch. The aviation socket is provided with at least a first socket and a second socket adapted to the aviation plug connected to the transmitter and receiver.

[0007] The first jack and the indicator are connected in series to form a first detection branch. The first detection branch is connected to both ends of the power supply body and is used to detect the microphone of the transmitter and receiver after the aviation plug is inserted into the aviation socket.

[0008] The second socket is connected in series with the limit switch to form a second detection branch. The second detection branch is connected to both ends of the power supply body and is used to detect the speaker of the transmitter and receiver after the aviation plug is inserted into the aviation socket.

[0009] As a further technical solution of this utility model, the first socket is equipped with a first terminal and a ninth terminal. When the aviation plug is inserted into the aviation socket, the first terminal and the ninth terminal are connected.

[0010] As a further technical solution of this utility model, at least two second detection branches are provided, and the two second detection branches respectively detect the left speaker and the right speaker of the headset.

[0011] As a further technical solution of this utility model, the second socket is equipped with a third terminal and a fourth terminal. When the aviation plug is inserted into the aviation socket, the third terminal and the fourth terminal are connected to detect the left speaker of the headset.

[0012] As a further technical solution of this utility model, the second socket is also equipped with a fifth terminal and a sixth terminal. When the aviation plug is inserted into the aviation socket, the fifth terminal and the sixth terminal are connected to detect the right speaker of the headset.

[0013] As a further technical solution of this utility model, the second detection branch is provided with at least three branches, two of which are grouped together to detect the left and right speakers of the headset microphone; the remaining branch is used to detect the speaker of the handheld microphone.

[0017] As a further technical solution of this utility model, it also includes a housing, on which the power supply body, aviation socket, indicator and limit switch are all mounted.

[0018] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0019] A first detection branch is formed by connecting the first socket of the aviation connector in series with an indicator. This first detection branch is connected between the positive and negative terminals of the power supply unit. It is used to test the microphone of the transmitter / receiver after the aviation plug is inserted into the aviation connector. When the tester presses the PTT (Push to talk) button of the transmitter / receiver, the complete circuit formed between the first detection branch and the power supply unit is connected. By observing whether the indicator emits an indication signal, it can be detected whether the connection cable corresponding to the microphone of the transmitter / receiver is connected correctly. A second detection branch is formed by connecting the second socket of the aviation connector in series with a limit switch. This second detection branch is connected between the positive and negative terminals of the power supply unit. It is used to test the speaker of the transmitter / receiver after the aviation plug is inserted into the aviation connector. When the tester closes the limit switch, the complete circuit formed between the second detection branch and the power supply unit is connected. By listening to whether the speaker of the transmitter / receiver emits a current sound, it can be detected whether the connection cable corresponding to the speaker of the transmitter / receiver is connected correctly. Therefore, the transmitter and receiver, after being modified in the control room, can be tested for connection at any time without having to take them to the actual work site for testing. This not only eliminates safety hazards but also effectively improves the efficiency of transmitter and receiver connection modification and maintenance. Attached Figure Description

[0033] Example 1

[0034] This embodiment is the first embodiment of this utility model. Please refer to [link / reference]. Figures 1 to 4 This embodiment provides a transmitter and receiver connection line detection device. The transmitter and receiver can be used in different fields, including aviation communication, ship communication and medical communication. The transmitter and receiver mentioned in this application are mainly adapted to the host of ship communication equipment.

[0035] The receiver / transmitter connection testing device specifically includes a power supply body 3, an aviation socket 2, an indicator 4, and a limit switch 5, wherein multiple limit switches 5 can be provided.

[0036] Please see Figure 2The aviation socket 2 provided in this embodiment is used to connect the transmitter and receiver to be tested and is compatible with the aviation plug connected to the transmitter and receiver. The aviation socket 2 is provided with at least a first socket 201 and a second socket 202 that are compatible with the aviation plug.

[0037] In particular, please see Figure 4 In this embodiment, the first jack 201 is connected in series with the indicator 4 to form a first detection branch, and the first detection branch is connected between the positive and negative terminals of the power supply body 3, for detecting the microphone of the receiver after the aviation plug is inserted into the aviation socket 2.

[0038] Therefore, when the tester presses the PTT (Push to talk) button on the microphone, the complete circuit formed between the first detection branch and the power supply body 3 is completed. At this moment, by observing whether the indicator 4 emits an indication signal, it can be detected whether the connection cable corresponding to the microphone of the microphone is connected correctly.

[0039] In particular, please continue reading Figure 4 In this embodiment, the second socket 202 is connected in series with the limit switch 5 to form a second detection branch, and the second detection branch is connected between the positive and negative terminals of the power supply body 3, for detecting the speaker of the receiver after the aviation plug is inserted into the aviation socket 2.

[0040] Therefore, when the tester closes the limit switch 5, the complete circuit formed between the second detection branch and the power supply body 3 is connected. At this moment, by listening to whether the speaker of the transmitter or receiver emits a current sound, it can be detected whether the connection wire corresponding to the speaker of the transmitter or receiver is connected correctly.

[0041] It should be noted that you should refer to [link / reference]. Figure 2 and Figure 3 In this embodiment, both the first socket 201 and the second socket 202 can be configured as multiple units, and they are arranged in pairs. Specifically, the first socket 201 is configured with a first terminal 2011 and a ninth terminal 2012 that can cooperate with the first terminal 2011. The second socket 202 is configured with a third terminal 2021, a fourth terminal 2022 that can cooperate with the third terminal 2021 to conduct electricity, a fifth terminal 2023, a sixth terminal 2024 that can cooperate with the fifth terminal 2023 to conduct electricity, a seventh terminal 2025, and an eighth terminal 2026 that can cooperate with the seventh terminal 2025 to conduct electricity.

[0042] Further, please refer to Figure 4Since the first jack 201 provided in this embodiment is equipped with a first terminal 2011 and a ninth terminal 2012, when the aviation plug is inserted into the aviation socket 2, the two terminals of the microphone of the transmitter and receiver are connected to the first terminal 2011 and the ninth terminal 2012 respectively. The first terminal 2011 and the ninth terminal 2012 are conductive, which means that the microphone of the transmitter and receiver is connected to the first detection branch. When the tester presses the PTT button of the transmitter and receiver, the first detection branch is powered on. If the indicator 4 emits an indication signal at this time, it indicates that the microphone of the transmitter and receiver has been correctly connected to the line.

[0043] The indicator 4 includes a buzzer, LED indicator lights, etc. Taking the buzzer as an example, when the operator presses the PTT button of the transmitter and receiver, if the buzzer sounds, it means that the microphone of the transmitter and receiver has been correctly connected to the line.

[0044] It should be noted that you should refer to [link / reference]. Figure 1 The aforementioned limit switch 5 can be a V-156-1C25 type limit switch, including three terminals: NC (normally closed), NO (normally open), and COM (common). The V-156-1C25 type limit switch is widely used in automation equipment, mechanical equipment, electronic equipment and other fields, such as limit control, position detection, and safety protection. Its stable and reliable performance and wide applicability make it an indispensable and important component in the field of industrial automation.

[0045] For further information, please refer to [link / reference]. Figure 4 In this embodiment, at least two second detection branches are provided. In this embodiment, two branches can be provided. The two second detection branches can detect the left speaker and the right speaker of the headset respectively.

[0046] On one of the second detection branches, the second jack 202 is equipped with a third terminal 2021 and a fourth terminal 2022. Therefore, when the aviation plug is inserted into the aviation socket 2, the two terminals of the left speaker of the headset are connected to the third terminal 2021 and the fourth terminal 2022 respectively. The third terminal 2021 and the fourth terminal 2022 are conductive, which means that the left speaker of the headset is connected to this second detection branch. When the tester presses the push rod of the first limit switch 501, this second detection branch is energized. If a current disturbance sound is heard from the left speaker of the headset at this time, it indicates that the left speaker of the headset has been correctly connected to the line.

[0047] On another second detection branch, the second jack 202 is equipped with a fifth terminal 2023 and a sixth terminal 2024. Therefore, when the aviation plug is inserted into the aviation socket 2, the two terminals of the right speaker of the headset are connected to the fifth terminal 2023 and the sixth terminal 2024 respectively. The fifth terminal 2023 and the sixth terminal 2024 are conductive, which means that the right speaker of the headset is connected to this second detection branch. When the tester presses the push rod of the second limit switch 502, this second detection branch is energized. If a current disturbance sound is heard from the right speaker of the headset at this time, it indicates that the right speaker of the headset is correctly connected to the line.

[0048] Furthermore, the receiver connection line testing device provided in this embodiment also includes a housing 1, a power supply body 3, an aviation socket 2, an indicator 4, and a limit switch, all of which are mounted on the housing 1. The housing 1 can be made of magnesium-aluminum alloy or glass fiber reinforced resin-based composite material.

[0049] In addition, the power supply body 3 provided in this embodiment can be a DC power source such as a dry cell battery or a storage battery, or it can be an AC power source. However, the AC power source needs to be used with a transformer to supply power to the device.

[0050] Example 2

[0051] This embodiment is the second embodiment of the present invention. Based on embodiment 1, this embodiment provides a further solution for detecting whether the speaker circuit of a handheld microphone is correctly connected.

[0052] Please continue reading. Figure 4 In this embodiment, at least three second detection branches are provided, and correspondingly, three limit switches 5 are provided, including a first limit switch 501, a second limit switch 502, and a third limit switch 503. Two of the second detection branches are grouped together to detect the left and right speakers of the headset microphone, respectively; while the remaining second detection branch is used to detect the speaker of the handheld microphone.

[0053] In the remaining second detection branch, the second jack 202 is equipped with a seventh terminal 2025 and an eighth terminal 2026. Therefore, when the aviation plug is inserted into the aviation socket 2, the two terminals of the handheld receiver speaker are connected to the seventh terminal 2025 and the eighth terminal 2026 respectively. The seventh terminal 2025 and the eighth terminal 2026 are conductive, which means that the handheld receiver speaker is connected to this second detection branch. When the tester presses the push rod of the third limit switch 503, this second detection branch is energized. If a current disturbance sound is heard from the handheld receiver speaker at this time, it indicates that the speaker of the handheld receiver has been correctly connected to the line.
