Description
Technical Field
[0001] The utility model belongs to the technical field of measuring devices, and particularly relates to a measuring device for stable power supply of automobiles. Background Technique
[0002] The power supply system of an automobile is a key component to ensure the normal operation of the vehicle. It is mainly responsible for providing necessary power for vehicle starting, ignition, lighting, electronic devices, and various sensors. The power supply system usually includes a storage battery, a generator, a voltage regulator, a starter, and related wires and connectors. The stability of the automobile power supply is the key to ensuring the normal operation of the automobile. The current stability is to measure the magnitude of the output current multiple times within a certain period of time, and then calculate the magnitude of the current stability.
[0003] In the measurement experiment, the current is measured once every minute, and the measurement time lasts for one hour. The clamp ammeter can measure the magnitude of the current in the wire without opening the circuit. For the commonly used clamp ammeter, after opening the opening, the wire to be measured is sent into the clamp ammeter for measurement. Since the loop hole of the clamp ammeter is relatively large, the wire can move freely inside after being sent in. Therefore, it is necessary to hold the clamp ammeter by hand to prevent it from moving. However, due to the long measurement time, tools are needed to clamp and fix the clamp ammeter during measurement. Summary of the Utility Model

The mutual inductance assembly 4 generates a mutual inductance current. By measuring the magnitude of the mutual inductance current generated by the mutual inductance assembly 4, the magnitude of the current in the output wire can be measured. If the mutual inductance current generated by the mutual inductance assembly 4 is stable, it can reflect the stability of the automobile power supply. When the output wire passes between the shell 11 and the U-shaped shell 12, the wire clamping assembly 6 can clamp the wire, and then clamp the device on the output wire for convenient real-time measurement.
[0022] As Figure 3 and 4As shown, the connecting component 2 includes a sleeve 21 fixedly connected to one end of the U-shaped shell 12, the sleeve 21 is movably sleeved on one end of the shell 11, a V-shaped groove 22 is provided at the bottom end of one side of the sleeve 21, a C-shaped clamp 23 is provided inside the V-shaped groove 22, both ends of the C-shaped clamp 23 are provided with folded edges 24, and a slide groove 25 is provided at the top of the other side of the sleeve 21. The positioning component 3 includes a cylinder 31 fixedly connected to one end of the shell 11, a clamping column 32 is slidably connected inside the cylinder 31, a second spring 35 is fixedly connected inside the clamping column 32, one end of the second spring 35 is fixedly connected to one end of the inner wall of the cylinder 31, the clamping column 32 passes through one side of the shell 11, one end of the clamping column 32 is fixedly connected to a reducing rod 33, one end of the reducing rod 33 is fixedly connected to a round handle 34, the outer diameter of the clamping column 32 is equal to the inner diameter of the C-shaped clamp 23, and the width of the opening of the C-shaped clamp 23 is equal to the diameter of the reducing rod 33.
[0023] According to the above structure, when measuring, the U-shaped shell 12 is first opened to place the wire between the U-shaped shell 12 and the shell 11, and then the clamping column 32 opens the opening of the C-shaped clamp 23 and squeezes into the interior of the C-shaped clamp 23 when the U-shaped shell 12 is pressed down, so that the sleeve 21 is clamped at one end of the shell 11. The setting of the folded edge 24 makes it easier for the clamping column 32 to squeeze the opening of the C-shaped clamp 23.
[0024] like Figure 4 As shown, one end of the U-shaped shell 12 is fixedly connected to an end plate 13 , one end inside the shell 11 is fixedly connected to a support plate 14 , and a first spring 15 is fixedly connected between the end plate 13 and the support plate 14 .

[0026] like Figure 1 and 2 As shown, the mutual inductance component 4 includes a first U-shaped iron core 41 and a second U-shaped iron core 42. The first U-shaped iron core 41 is fixedly connected to the inside of the U-shaped shell 12, and the second U-shaped iron core 42 is fixedly connected to the top of the shell 11. A mutual inductance coil winding 43 is arranged at the bottom of the second U-shaped iron core 42. The mutual inductance coil winding 43 is electrically connected to the ammeter 5. Both ends of the first U-shaped iron core 41 are fixedly connected with an insert 44, and the two inserts 44 are movably mounted on the two ends of the second U-shaped iron core 42 respectively.
[0027] According to the above structure, after the U-shaped shell 12 is closed, the inserts 44 at both ends of the first U-shaped core 41 are respectively sleeved on both ends of the second U-shaped core 42, so that the first U-shaped core 41 and the second U-shaped core 42 form a closed loop. When the wire is energized, the mutual inductance coil winding 43 will generate an induced current, and the ammeter 5 can measure this induced current.
[0028] like Figure 2 and 4 As shown, the wire clamping assembly 6 includes two symmetrically arranged wire clamping plates 61, which are respectively fixedly connected to the top end of the inner side of the shell 11 and the bottom end of the inner side of the U-shaped shell 12, and are provided with semicircular grooves 62 distributed equally.

[0030] The working principle of the utility model is as follows: when measuring, the U-shaped shell 12 is first opened to place the wire between the U-shaped shell 12 and the shell 11, and then the clamping column 32 opens the opening of the C-shaped clamp 23 and squeezes into the interior of the C-shaped clamp 23 when the U-shaped shell 12 is pressed down, so that the sleeve 21 is clamped at one end of the shell 11. The setting of the folded edge 24 facilitates the clamping column 32 to squeeze the opening of the C-shaped clamp 23. When opening the U-shaped shell 12, it is only necessary to press the round handle 34 inward to make the reducing rod 33 pass through the opening of the C-shaped clamp 23. Under the elastic force of the first spring 15, the U-shaped shell 12 is automatically lifted up and opened. After the U-shaped shell 12 is closed, the first U-shaped The inserts 44 at both ends of the iron core 41 are respectively sleeved on the two ends of the second U-shaped iron core 42, so that the first U-shaped iron core 41 and the second U-shaped iron core 42 form a closed loop. When the wire is energized, the mutual inductance coil winding 43 will generate an induced current, and the ammeter 5 can measure this induced current. When the wire passes through the opening between the U-shaped shell 12 and the shell 11, it will enter between the two clamping plates 61, and then slide the wire between the corresponding two semicircular grooves 62 according to the diameter of the wire.
