Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a combined structure of a mutual inductor and a sensor. Background Art

[0002] A transformer, also known as an instrument transformer, is a general term for current transformers and voltage transformers. It is a primary device that connects primary and secondary electrical systems. A sensor is a device that can sense and measure changes in physical, chemical, or biological parameters and convert them into readable or processable signals.

[0003] In the existing technology, transformers and sensors are two separate products. Customers purchase transformers or sensors, or both products according to their business needs, and they need to be installed separately during installation. In addition, the total purchase cost is higher, and the installation space of the two products is larger. Utility Model Content

[0004] Based on the existing sensor technology problems, the utility model proposes a combined structure of a mutual inductor and a sensor.

[0005] The utility model proposes a combined structure of a mutual inductor and a sensor, comprising a mutual inductor and a sensor, wherein the mutual inductor and the sensor are detachably fixed, the mutual inductor comprising a mutual inductor plastic shell, the sensor comprising a sensor upper cover and a sensor lower cover, a first conical hole penetrating the mutual inductor plastic shell is provided on one side of the top of the mutual inductor plastic shell, four second conical holes penetrating the sensor upper cover are equidistantly provided on the top of the sensor upper cover, four third conical holes penetrating the sensor lower cover are equidistantly provided on the top of the sensor lower cover, and a first cylindrical copper busbar is plugged and fixed inside the first conical hole, the third conical hole and the second conical hole.

[0006] Preferably, the first conical hole, the third conical hole and the second conical hole are the same in size and appearance, and the central axes of the first conical hole, the third conical hole and the second conical hole are consistent with the central axis of the first conical hole, the upper part of the first conical hole and the foot of the first cylindrical copper busbar are a clearance fit, and the lower part of the first conical hole and the foot of the first cylindrical copper busbar are an interference fit.

[0007] Through the above technical solution, the central axes of the first conical hole, the third conical hole, the second conical hole and the first conical hole are all consistent. The same aperture and consistent central axis ensure that the mutual inductor and the sensor can be accurately aligned during assembly, reducing assembly errors and improving the overall accuracy of the product. The upper part of the first conical hole and the foot of the first cylindrical copper busbar are clearance fit, which is convenient for assembly and disassembly; the lower part of the first conical hole and the foot of the first cylindrical copper busbar are interference fit, which ensures a tight connection between the copper busbar and the hole position and improves the stability and reliability of the connection.

[0008] Preferably, a PIN needle is fixedly provided on a side of the mutual inductor plastic shell opposite to the first conical hole, and the PIN needle passes through the second conical hole and the third conical hole to the outside of the bottom of the sensor lower cover.

[0009] With the above technical solution, since the PIN needle is fixed inside the transformer plastic shell, during assembly, it is only necessary to align the sensor upper cover and the sensor lower cover with the transformer plastic shell, and the PIN needle will automatically align, which simplifies the assembly steps and makes it easy to assemble the sensor and transformer.

[0010] Preferably, a second card slot is provided at the top inner side of the sensor upper cover, a first card slot is provided at the bottom of the mutual inductor plastic shell, and a card block is fixedly provided at the middle of the first card slot.

[0011] Through the above technical solution, by setting the first card slot, the card block and the second card slot, the assembly between the mutual inductor plastic shell and the sensor cover becomes simple and quick. It only needs to insert the card block into the second card slot, and the protruding end of the sensor cover is inserted between the card block and the first card slot to complete the fixation without the need for complicated screws or other fixing devices. In addition, due to the structure of the first card slot, the card block and the second card slot, the mutual inductor and the sensor can be easily separated, which is convenient for maintenance, replacement or upgrading.

[0012] Preferably, the clamping part of the mutual inductor plastic shell is set to be F-shaped, and the clamping part of the sensor upper cover is set to be T-shaped.

[0013] Through the above technical solution, the F-shaped and T-shaped clamping structures provide more contact areas and locking points, making the connection between the transformer plastic shell and the sensor cover more secure and not easy to loosen.

[0014] Preferably, the mutual inductor and the sensor can be detached and used separately.

[0015] Through the above technical solution, users can choose whether to use the transformer and sensor at the same time, or use one of them alone, according to specific application requirements, which increases the flexibility of use. In addition, using the transformer or sensor alone can adapt to different working environments or circuit requirements, making the product have a wider range of applications.

[0016] The beneficial effects of the present invention are:

[0017] 1. The design of the conical hole, cylindrical copper busbar, first slot, block, and second slot enables quick and precise assembly, simplifying disassembly and assembly and facilitating maintenance and component replacement. The first, second, and third conical holes are identical in size and appearance, and their central axes are aligned, ensuring smooth and accurate insertion of the copper busbar and improving assembly efficiency.

[0018] 2. The mutual inductor and sensor can be detached and used separately, making the product adaptable to different application scenarios. Users can choose to use mutual inductors, sensors or a combination of the two according to actual needs, which increases the flexibility and market applicability of the product.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-Figure 5A combined structure of a mutual inductor and a sensor includes a mutual inductor 1 and a sensor 2, wherein the mutual inductor 1 and the sensor 2 are detachably fixed, the mutual inductor 1 includes a mutual inductor plastic shell 101, the sensor 2 includes a sensor upper cover 201 and a sensor lower cover 202, a first conical hole 103 penetrating the mutual inductor plastic shell 101 is opened on one side of the top of the mutual inductor plastic shell 101, four second conical holes 206 penetrating the sensor upper cover 201 are opened at equal intervals on the top of the sensor upper cover 201, four third conical holes 204 penetrating the sensor lower cover 202 are opened at equal intervals on the top of the sensor lower cover 202, and a first cylindrical copper bus 102 is plugged and fixed inside the first conical hole 103, the third conical hole 204 and the second conical hole 206.

[0027] Further, refer to Figure 3 The first conical hole 103, the third conical hole 204 and the second conical hole 206 are the same in size and appearance, and the central axes of the first conical hole 103, the third conical hole 204 and the second conical hole 206 are consistent with the central axis of the first conical hole 103. The upper part of the first conical hole 103 and the foot of the first cylindrical copper busbar 102 are clearance fit, and the lower part of the first conical hole 103 and the foot of the first cylindrical copper busbar 102 are interference fit.

[0028] The central axes of the first conical hole 103, the third conical hole 204, the second conical hole 206 and the first conical hole 103 are all consistent. The same aperture and consistent central axis ensure that the mutual inductor and the sensor can be accurately aligned during assembly, reducing assembly errors and improving the overall accuracy of the product. In addition, the upper part of the first conical hole 103 and the foot of the first cylindrical copper busbar 102 are clearance fit, which is convenient for assembly and disassembly; the lower part of the first conical hole 103 and the foot of the first cylindrical copper busbar 102 are interference fit, which ensures a close connection between the copper busbar and the hole position and improves the stability and reliability of the connection.

[0029] Further, refer to Figure 3 A PIN needle 104 is fixedly provided on the side of the mutual inductor plastic shell 101 opposite to the first conical hole 103, and the PIN needle 104 passes through the second conical hole 206 and the third conical hole 204 to the outside of the bottom of the sensor lower cover 202.

[0030] Since the PIN needle 104 is fixed inside the transformer plastic shell, during assembly, it is only necessary to align the sensor upper cover 201 and the sensor lower cover 202 with the transformer plastic shell 101, and the PIN needle 104 will automatically align, simplifying the assembly steps and making it easy to assemble the sensor 2 and the transformer 1.

[0031] Further, refer to Figure 2 and Figure 4A second slot 205 is provided at the top inner side of the sensor cover 201 , a first slot 105 is provided at the bottom of the mutual inductor plastic shell 101 , and a card block 106 is fixedly provided at the middle of the first slot 105 .

The clamping block 106 only needs to be inserted into the second slot 205, and the protruding end of the sensor cover 201 is clamped between the clamping block 106 and the first slot 105 to complete the fixation. No complicated screws or other fixing devices are required. In addition, due to the structure of the first slot 105, the clamping block 106 and the second slot 205, the mutual inductor 1 and the sensor 2 can be easily separated, which is convenient for maintenance, replacement or upgrading.

[0033] Further, refer to Figure 4 The clamping part of the mutual inductor plastic shell 101 is set to be F-shaped, and the clamping part of the sensor cover 201 is set to be T-shaped, so that when the mutual inductor 1 and the sensor 2 are fixed, the protruding part of the sensor cover 201 above the second clamping slot 205 is clamped between the top of the clamping block 106 and the top of the first clamping slot 105, and the clamping block 106 is simultaneously clamped into the inside of the second clamping slot 205, making the fixation of the mutual inductor 1 and the sensor 2 more stable.

[0034] The F-shaped and T-shaped clamping structures provide more contact areas and locking points, so that the connection between the mutual inductor plastic shell 101 and the sensor upper cover 201 is more secure and not easy to loosen.

[0035] Preferably, refer to Figure 1 and Figure 3 The mutual inductor 1 and the sensor 2 can be detached and used separately, and when the sensor 2 is used alone, its four third conical holes 204 and second conical holes 206 can be connected to one to four second cylindrical copper busbars 203 according to usage requirements.

[0036] During use, users can choose whether to use transformer 1 and sensor 2 simultaneously, or use one of them alone, according to specific application requirements, which increases the flexibility of use. In addition, using transformer 1 or sensor 2 alone can adapt to different working environments or circuit requirements, making the product have a wider range of applications.

A PIN needle 104 is fixedly provided on one side of the mutual inductor 1 and the sensor 2, so that the PIN needle 104 passes through the second conical hole 206 and the third conical hole 204 to the outside of the bottom of the sensor lower cover 202, and then the first cylindrical copper busbar 102 is inserted between the first conical hole 103, the second conical hole 206 and the third conical hole 204, so that the mutual inductor 1 and the sensor 2 are further fixed; when the mutual inductor 1 and the sensor 2 are used separately, the four third conical holes 204 and the second conical holes 206 set on the sensor 2 can be connected to one to four second cylindrical copper busbars 203 according to usage requirements.
