[0020] All features disclosed in this specification, and / or all steps of any methods or processes disclosed in this specification, can be combined in any manner, except where features or steps are mutually exclusive.

[0021] Any feature disclosed in this specification, unless stated otherwise, can be replaced by any equivalent or similar feature, or by a feature that is technically equivalent or similar in function. That is, each feature is one example only of a range of equivalent or similar features.

[0022] As Figs. 1-3 The utility model discloses a connector's detection equipment with test port, including equipment host computer, the equipment host computer includes PCB mainboard 6, 26PIN socket 5, 26PIN plug 3, voltage display 2, switch 4 and casing 1. 26PIN plug is connected with the test port of PCB mainboard through 26PIN socket, and the PCB mainboard is used to detect the state of equipment, and voltage display is electrically connected with the PCB mainboard and is used to show the voltage state of equipment, and the casing is used to cover PCB mainboard, 26PIN plug, 26PIN socket and voltage display to protect the internal structure of equipment and prevent external environment interference.

[0023] The switch is used for controlling the selection of detection channel, and a user can switch the conduction state of relay by manually operating the switch, thereby selecting different detection channels. A relay control module is arranged on the PCB mainboard, and the relay control module includes a plurality of relays (RLY1, RLY2, RLY3, RLY4). By controlling the conduction and disconnection of the relays, the switching of different voltage detection channels is realized. For example, when the switch is closed, the relay is turned on, the voltage detection channel is activated, and the voltage signal can be transmitted to the voltage display for real-time display.

[0024] To ensure the stability of the voltage signal, the equipment host computer further includes rectifier diodes (such as D1~D15), which are connected in series in the circuit and are used for rectifying the voltage input signal to ensure the stability and accuracy of the voltage detection signal. By the unidirectional conduction characteristic of the rectifier diode, reverse current interference to other detection channels can be effectively prevented, the independence between the detection channels is ensured, and the accuracy of the voltage detection result is ensured.

[0025] The device host further comprises a plurality of voltage indication modules corresponding to different detection channels.

[0026] To protect the safe operation of the device host under overvoltage conditions, the device host further comprises a voltage protection module composed of a pressure-sensitive resistor (MOV1) and a gas discharge tube (GDT1). When the input voltage exceeds the normal working range, the pressure-sensitive resistor will quickly absorb the surge current to reduce the voltage impact, and at the same time the gas discharge tube will quickly conduct under overvoltage conditions to discharge excess voltage, thereby protecting the subsequent circuit from damage. This protection design can ensure the long-term stable operation of the device host in complex power environments.

[0027] In addition, the device host further comprises a power voltage conversion module that converts the input voltage through a voltage stabilizing power supply (U1, URB4812ZP-6WR3). The power voltage conversion module converts the input power voltage (such as 12V) into a stable output voltage for the PCB mainboard and voltage display, ensuring stable power supply for the entire circuit system. The application of the power voltage conversion module enables the device host to maintain a stable working state under voltage fluctuations, avoiding inaccurate detection results caused by unstable power supply.

[0028] The housing of the device host comprises an upper housing 11 and a lower housing 12, which are connected by screws or buckles to form a closed structure for covering the PCB mainboard, 26PIN plug, 26PIN socket and voltage display and other components.

[0029] The utility model discloses a relay control module realizes the switching of different detection channels, ensures the stability of detection signal through rectifier diode, shows the state of equipment through voltage indication module, guarantees the security of circuit through voltage protection module, and provides stable power supply through power voltage conversion module, finally realizes the voltage detection of equipment under the electrified state quickly and safely. This detection equipment has reasonable structure, and simple operation can satisfy the demand of equipment state real-time monitoring and fault diagnosis.

[0030] As Fig. 3As shown, the utility model can detect under the condition of uninterrupted power supply, and the input voltage protection and stability are realized by the combination of key elements such as pressure sensitive resistance (MOV1), gas discharge tube (GDT1) and voltage stabilizing module (U1) in circuit design, ensuring the safe operation of the circuit under the live state. The pressure sensitive resistance MOV1 is used to absorb the sudden overvoltage surge, and the gas discharge tube GDT1 rapidly conducts and discharges the excess voltage under the overvoltage condition, thereby protecting the subsequent circuit elements. Through the voltage stabilizing power module U1 (URB4812ZP-6WR3), the input voltage is stably converted into 12V DC voltage, providing stable power supply for the PCB mainboard and each functional module. In addition, the relay module (RLY1, RLY2, RLY3, RLY4) cooperates with the control switch (SW1, SW2), and the switching and isolation of different voltage detection channels are realized through the rectifier diode (D1~D15), ensuring no interference between channels and guaranteeing the accuracy and stability of the detection signal. The user can quickly switch the detection channel under the control of the relay by operating the switch SW1, SW2, without interrupting the power supply of the equipment, and the detection signal is fed back in real time through the voltage display (D4, D8, D12, D15), thereby realizing the uninterrupted detection of the equipment state. In addition, the rectifier diode not only realizes signal rectification, but also reversely isolates the circuit, preventing mutual interference between different channel voltages, and the orderly switching of the relay between different channels further guarantees the continuity and safety of the detection. Therefore, through the organic cooperation of the input voltage protection module, the voltage stabilizing power supply module, the relay switching module and the voltage display module, the utility model can realize the detection of the equipment state under the live state, improving the safety, convenience and stability of the detection.

[0031] The above is only a specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any change or replacement without creative labor should be covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be limited to the protection scope defined in the claims.
