Description

Technical Field

[0001] This utility model belongs to the field of sensor technology, specifically relating to a current sensor housing structure. Background Technology

[0002] The main function of a current sensor is to convert the current signal in a circuit into a measurable voltage or digital signal, enabling real-time monitoring, control, and protection of the current. The current sensor is installed on a support frame near the car battery. The car current sensor monitors the charging and discharging current of the battery in real time to prevent overcharging or over-discharging and extend battery life.

[0003] For example, in the Chinese utility model with announcement number CN217360040U, entitled "A Current Sensor Housing Structure for a High-Precision Electricity Meter", although the rounded corners at the edges of the top and bottom covers facilitate production, save space, and increase the sealing when the top and bottom covers are joined, if a car drives on a bumpy road, the current sensor will vibrate, and prolonged vibration will cause the internal components of the current sensor to fall off. Utility Model Content

[0004] The purpose of this utility model is to provide a current sensor housing structure that is simple in structure and reasonably designed in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A current sensor housing structure includes a sensor body, a buffer assembly fixedly connected to the bottom of the sensor body, and a wire through hole on the side of the sensor body, through which a data line electrically connected to the sensor body passes.

[0007] As a further optimization of this utility model, the sensor body has several heat dissipation holes on its side, and a second connecting plate is fixedly connected to the side of the sensor body. The second connecting plate is fixedly connected to the buffer assembly by screws.

[0008] As a further optimization of this utility model, the buffer assembly includes a support plate fixedly connected to the second connecting plate, a base is provided on the outside of the support plate, springs fixedly connected to the bottom of the inner wall of the base are fixedly connected to the four corners of the bottom of the support plate, and a plurality of dampers rotatably connected to the bottom of the inner wall of the base are rotatably connected around the support plate.

[0009] As a further optimization of this utility model, a plurality of first connecting plates are fixedly connected to the outer side of the base, and each of the plurality of first connecting plates is provided with a fixing hole.

[0010] As a further optimization of this utility model, a filter screen located on the side of the heat dissipation hole is fixedly connected to the side of the sensor body by screws.

[0011] As a further optimization of this utility model, the upper surface of the support plate is provided with several holes, and a cavity is provided between the base and the support plate.

[0012] The beneficial effects of this utility model are as follows: When the sensor body vibrates, the upper and lower forces are buffered by the cooperation of the base, support plate and spring. Then, the left and right forces are buffered by the cooperation of the support plate, rotating part, damper and base. This prevents the internal components of the sensor body from falling off due to long-term vibration and extends the overall service life of the sensor body. Attached Figure Description

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1

[0020] like Figure 1 , Figure 2 and Figure 4As shown, a current sensor housing structure includes a sensor body 1. A wire hole is provided on the side of the sensor body 1, through which a data cable 3 passes. The data cable 3 is electrically connected to a battery (not shown in the figure). The sensor body 1 monitors the battery in real time to prevent overcharging and extend battery life. Several heat dissipation holes 4 are provided on the side of the sensor body 1 to dissipate heat and prevent overheating that could damage internal components. A filter screen 5 is fixedly connected to the side of the sensor body 1 by screws. The filter screen 5 is located next to the heat dissipation holes 4 and blocks external dust and other debris from entering the sensor body 1 and damaging its internal components.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, a second connecting plate 6 is fixedly connected to the side of the sensor body 1. The second connecting plate 6 is fixedly connected to the support plate 202. The second connecting plate 6 and the support plate 202 are fixed with screws, which facilitates the installation and disassembly of the sensor body 1 and facilitates subsequent maintenance and replacement of the sensor body 1. A base 201 is provided on the outside of the support plate 202. The base 201 protects the internal components and prevents stones or other debris from colliding with the components inside the base 201, which would affect the service life of the components. Several holes are opened on the upper surface of the support plate 202 to dissipate heat from the sensor body 1 and prevent heat from accumulating at the bottom. A cavity is provided between the base 201 and the support plate 202. Springs 203 are fixedly connected to the four corners of the bottom of the support plate 202. The springs 203 are fixed to the base 202. The bottom of the inner wall of the base 201 is fixedly connected. When the sensor body 1 vibrates, the spring 203 buffers the vertical force. Several dampers 204 are rotatably connected around the support plate 202. The dampers 204 are rotatably connected to the bottom of the inner wall of the base 201. In this embodiment, there are four dampers 204. The specific number can be changed according to the actual situation. The dampers 204 buffer the front, back and left and right sides of the sensor body 1 to avoid the movement of the internal components of the sensor body 1 due to vibration, which would cause problems with signal transmission. Several first connecting plates 205 are fixedly connected to the outside of the base 201. Each of the first connecting plates 205 has a fixing hole. The first connecting plates 205, fixing holes and screws facilitate the overall installation and disassembly, and also facilitate the subsequent maintenance of the whole.

[0022] It should be noted that, in use, the current sensor housing structure is fixed to the mounting bracket (not shown in the diagram) inside the car by the operator using screws and the first connecting plate 205. Then, it is connected to the battery (not shown in the diagram) via the data cable 3 to test the battery. When the sensor body 1 is working, it dissipates heat through the heat dissipation holes 4 and blocks external debris through the filter screen 5. If vibration occurs, it is buffered by the cooperation of the spring 203 and the damper 204 to prevent the internal components of the sensor body 1 from falling off due to prolonged vibration, thus extending the service life of the sensor body 1.

[0023] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
