Description

Technical Field

[0001] This utility model relates to the field of electrical measuring instrument technology, and more specifically, to a multi-channel electrical measuring instrument. Background Technology

[0002] Electrical measuring instruments are instruments that compare measured electrical quantities or parameters with electrical standards or provide accurate ratios. A large number of measuring instruments used in scientific research, measurement transfer, and industrial testing fall under the category of electrical measuring instruments. They have a wide range of applications and occupy an important position in the field of metrology and testing.

[0003] Existing electrical measuring instruments only have one socket, so they can only measure multiple electrical devices at a time and cannot measure multiple electrical devices simultaneously. This results in long measurement times and low efficiency. Furthermore, when not in use, the socket is exposed to the outside environment, which may cause water or dust to enter and damage the device. Also, when connecting the socket and the plug, accidental contact may cause the plug to detach, affecting subsequent measurement results. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5This utility model provides a multi-channel electrical measuring instrument, including a housing 1. An electrical measuring connection component 2 is provided inside the housing 1. Through the electrical measuring connection component 2 inside the housing 1, the measuring equipment is connected and working, ensuring that there is no loosening after insertion. This allows for the measurement of multiple electrical devices, improving overall efficiency. An upper groove 3 is provided at the top front end of the housing 1. A sealing cover 5 is rotatably installed in the upper groove 3 via a rotating shaft 4. Rubber sealing strips 6 are adhered to both sides of the sealing cover 5. A lower sealing groove is installed at the bottom front end of the housing 1. Rubber pads 7 are provided on both sides of the inner wall of the lower sealing groove. The sealing cover 5, connected via the rotating shaft 4, works with the rubber sealing strips 6 to seal and protect the front end of the housing 1, preventing damage from water stains or dust when not in use. A power acquisition component 8 is installed on the back of the housing 1, which provides power while simultaneously acquiring information.

[0023] Please refer to the instruction manual appendix. Figure 2 As shown, the electrical connection component 2 includes an inner connection groove 9 formed inside the housing 1. An electrical connection hole 10 is provided inside the inner connection groove 9, and a clamping electrical component is provided inside the electrical connection hole 10. Abutment limiting components 11 are provided on both sides of the inner wall of the inner connection groove 9. After the plug is inserted through the electrical connection hole 10 inside the inner connection groove 9, the clamping electrical component ensures that the metal contacts on the plug will not loosen or fall off, achieving a dual positioning effect in conjunction with the abutment limiting components 11.

[0024] Please refer to the instruction manual appendix. Figure 3 As shown, the contact limiting component 11 includes inner through holes 12 formed on both sides inside the inner connecting groove 9. A contact block 13 is slidably disposed within the inner through hole 12. Adjustment grooves 14 are symmetrically formed on the housing 1 and communicate with the inner through holes 12. A fixing block 15 is fixedly connected to one end of the contact block 13 located within the inner through hole 12. An adjusting threaded post 16, penetrating the adjusting groove 14, is fixed to the fixing block 15. A limiting nut 17 is threaded onto one end of the adjusting threaded post 16 located outside the adjusting groove 14. By loosening the limiting nut 17, the adjusting threaded post 16, under the action of the fixing block 15, causes the contact block 13 to extend out of the inner through hole 12, thereby achieving a contact support effect for the plug.

[0025] Please refer to the instruction manual appendix. Figure 4As shown, the clamping energizing component includes metal clamping plates 18 located inside the housing 1. A U-shaped elastic metal sheet 19 is integrally connected between the bottom ends of the metal clamping plates 18, and an electrical contact groove is formed between the two metal clamping plates 18 within the U-shaped elastic metal sheet 19. Insulating rubber plates 20 are fixedly connected to the outer walls of each metal clamping plate 18.

Abutment springs 21 are symmetrically arranged between the insulating rubber plate 20 and the abutment baffle 22. By inserting the metal piece from the plug of the electrical device between the metal clamping plates 18, the U-shaped elastic metal sheet 19 is abutted by the abutment springs 21. Under the force applied to the metal clamping plates 18, inserting the metal piece between the two metal clamping plates 18 allows the metal piece to maintain a stable state through a reaction force. The insulating rubber plate 20 provides external insulation.

[0026] Please refer to the instruction manual appendix. Figure 5 As shown, the power acquisition assembly 8 includes an open-type insulating box 23, which is integrally connected to the housing 1. A partition plate 25 is fixed inside the open-type insulating box 23. A power supply battery 24 is installed on one side of the partition plate 25. A control button 29 connected to the power supply battery 24 is provided on the open-type insulating box 23. A control circuit board 26 is installed on the side of the partition plate 25 away from the power supply battery 24. A data acquisition card 27 and a signal processing module 28 are installed on the control circuit board 26. The data acquisition card 27 includes multiple individual channels. The power supply battery 24 supplies power to the control circuit board 26, enabling the data acquisition card 27 and the signal processing module 28 to perform data detection. Simultaneously, the signal processing module 28 processes and analyzes the received electrical signals. The data acquisition card 27 has multiple individual channels, enabling multi-channel electrical measurement.

[0027] In practical applications, the electrical connection component 2 installed inside the housing 1 ensures stable connection between the electrical measuring equipment and the device, preventing loosening after insertion. This allows for the measurement of multiple electrical devices, improving overall efficiency. The sealing cover 5 connected via the rotating shaft 4, in conjunction with the rubber sealing strip 6, seals the front end of the housing 1, preventing damage from water or dust when not in use. The power acquisition component 8 provides power while simultaneously collecting information. This invention features a simple structure, ease of use, and ensures stable connection with electrical equipment, preventing loosening. It also enables simultaneous testing of multiple devices, improving testing efficiency and providing excellent protection.
