Description

Technical Field

[0001] This utility model relates to the field of electronic sensor housing structure technology, and in particular to a current sensor housing and a current sensor. Background Technology

[0002] In industrial automation, power monitoring, and other scenarios, electronic current sensors need to adapt to diverse installation environments and functional expansion requirements. Traditional current sensor housings are typically fixed, single-unit structures with pre-configured dimensions, shapes, and functional interfaces, making it difficult to match different spatial layouts or multi-channel current monitoring needs. For example, when integrating multiple sensors into the same device, a custom-designed integral housing is often required, leading to increased installation costs, reduced space utilization, and limited maintenance efficiency.

[0003] Therefore, it is urgent to propose a current sensor housing and a current sensor to solve the above problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a current sensor housing, including at least two detachably connected housing units; the at least two housing units are stacked sequentially from top to bottom;

[0006] The housing unit includes a housing body and a connector; the housing body is provided with a mounting cavity for mounting a Rogowski coil or an extended coil; one side of the housing body extends outward to form a protrusion, and there is an operating space between the protrusion and the mounting cavity; the connector is installed on the side of the protrusion away from the mounting cavity.

[0007] Furthermore, the shell body has a ring-shaped structure.

[0008] Furthermore, the housing body is provided with wire holes for allowing the wires of the Rogowski coil or extended coil to pass through the housing body.

[0009] Furthermore, the housing body is made of insulating material.

[0010] Furthermore, the mounting cavity has a ring-shaped structure.

[0014] Furthermore, the connector is provided with feet for fixing the housing unit in the installation position.

[0015] Furthermore, a guide structure is provided between two adjacent housing units to align the two housing units.

[0016] In addition, this utility model also proposes a current sensor, including a current sensor housing as described above, and further including a Rogowski coil and an extended coil; the Rogowski coil and the extended coil are respectively installed in mounting cavities in different housing units.

[0017] Through the above technical solution, this utility model has the following beneficial effects:

[0018] With its detachable, stackable housing units, users can freely increase or decrease the number of housing units according to their actual needs. This not only meets the requirements of single-channel current detection scenarios but also enables multi-channel synchronous monitoring by stacking multiple housing units, significantly improving the flexibility and space utilization of equipment deployment.

Detailed Implementation

[0023] The following is a more detailed description of a current sensor housing and a current sensor according to the present invention, with reference to the accompanying drawings, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the present invention.

[0024] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0025] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a convenient and practical current sensor housing, including at least two detachably connected housing units 1; the at least two housing units 1 are stacked sequentially from top to bottom. By stacking at least two housing units 1, for example, the first layer of housing units 1 is used to install a Rogowski coil 2, and the remaining layers are used to install an extension coil 3, so users can freely increase or decrease the number of housing units 1 in the remaining layers according to actual needs, realizing rapid switching between single-channel or multi-channel current detection, significantly improving the flexibility of equipment deployment and space utilization; the disassembly and assembly process does not require complex tools, simplifying the maintenance process and reducing operation and maintenance costs.

[0026] Specifically, the housing unit 1 includes a housing body 11 and a connector 12; the housing body 11 has a mounting cavity 110 for mounting a Rogowski coil 2 or an extended coil 3; one side of the housing body 11 extends outward to form a protrusion 13, and there is an operating space 14 between the protrusion 13 and the mounting cavity 110; the connector 12 is installed on the side of the protrusion 13 away from the mounting cavity 110. The mounting cavity 110 provides a standardized interface, compatible with the quick installation of different types of coils; the protrusion 13 and the operating space 14 facilitate wiring and debugging operations, avoiding tool interference; the connector 12 and the housing body 11 have a separate structure, supporting the individual replacement of damaged parts and reducing maintenance costs.

[0027] The connector 12 is used to connect and fix the housing unit 1 to the external structure, thereby ensuring the stability of the current sensor in the installation position.

[0028] Preferably, the housing body 11 is a ring structure. The ring structure evenly distributes mechanical stress, enhances the overall pressure resistance and deformation resistance of the housing, and ensures the installation accuracy and long-term stability of the coil.

[0029] In one embodiment, the housing body 11 is provided with wire holes (not shown in the figure for simplicity) for the wires of the Rogowski coil 2 or the extended coil 3 to pass through the housing body 11. This avoids messy cable tangling, reduces the risk of electromagnetic interference, and improves the aesthetics and safety of the wiring.

[0030] In one embodiment, the housing body 11 is made of insulating material. The insulating material effectively isolates the current sensor from external conductive components, preventing leakage or short circuit accidents and ensuring the safe operation of the equipment in high-voltage environments.

[0031] In this embodiment, the mounting cavity 110 is a ring structure. The ring cavity matches the ring-shaped characteristics of the Rogowski coil 2, optimizing the magnetic field induction path, reducing measurement errors, and improving current detection accuracy.

[0032] In this embodiment, the mounting cavity 110 is provided with a fixing slot (not shown in the figure for simplicity) and a wiring terminal (not shown in the figure for simplicity). The fixing slot enables quick positioning and mechanical locking of the coil to prevent displacement; the wiring terminal provides a standardized electrical interface, simplifies the connection steps between the coil and the external circuit, and reduces installation complexity.

[0033] In one embodiment, the connector 12 has a first mounting hole 120; the protrusion 13 has a second mounting hole 130 that mates with the first mounting hole 120; the connector 12 is installed to the housing body 11 by bolts 15 passing through the first mounting hole 120 and the second mounting hole 130. The bolt connection method balances installation firmness and disassembly convenience, avoiding the problem of easy loosening of traditional snaps; the standardized hole settings improve the precise alignment between multiple housing units 1, improving assembly efficiency.

[0034] In this embodiment, the length of the connector 12 is greater than the length of the protrusion 13, which facilitates the setting of subsequent mounting holes.

[0035] In one embodiment, the connector 12 has a stepped structure. The stepped structure forms a multi-level limiting surface, which helps to vertically align adjacent housing units 1, prevents installation misalignment, and disperses stress at the connection point, thereby extending the service life of the connector 12.

[0036] Preferably, a guide structure (not shown in the figure for simplicity) is provided between two adjacent housing units 1 to align the two housing units 1. The guide structure enables rapid self-alignment of multiple housing units 1, reduces manual alignment errors, improves the coaxiality of the stacked housings, and enhances measurement consistency.

[0037] As an example, the wire structure includes protrusions and grooves, with protrusions and grooves respectively provided at the edges of one housing unit 1 and another adjacent housing unit 1. By matching the protrusions and grooves, the adjacent housing units 1 can be quickly aligned.

[0038] In this embodiment, the connector 12 is provided with feet for fixing the housing unit 1 in the installation position.

[0039] In addition, continue to refer to Figures 1-3 As shown, this embodiment also proposes a current sensor, including a current sensor housing as described above, and further including a Rogowski coil 2 and an extension coil 3. The Rogowski coil 2 and the extension coil 3 are respectively installed in mounting cavities 110 within different housing units 1. More specifically, the Rogowski coil 2 is installed in the mounting cavity 110 of the housing unit 1 for detecting current signals; the extension coil 3 is optionally installed in the mounting cavity 110 of another housing unit 1 for extending the measurement range or function of the current sensor.

[0040] In this embodiment, such as Figure 2 As shown, a Rogowski coil 2 or an extended coil 3 is embedded in the annular mounting cavity 110 of each housing unit 1, allowing a single housing unit 1 to independently complete the magnetic field induction of a single-channel current. When it is necessary to expand the detection channel, multiple housing units 1 can be vertically stacked, for example, by connecting them with bolts 15, to form a multi-layer independent detection unit, such as... Figure 3 As shown. After stacking, the axes of each layer of coils automatically remain coaxial (ensuring this through a guiding structure), ensuring spatial consistency of the multi-channel magnetic field signals. Since each housing unit 1 is relatively independent, when a fault occurs in a housing unit 1 or its internal coil, the problematic component can be quickly located. Only the relevant combination bolts 15 need to be unscrewed to separate the faulty housing unit 1 for replacement or repair; the entire sensor does not need to be disassembled, significantly shortening maintenance time, reducing maintenance costs, and effectively improving equipment availability and maintenance efficiency.

[0041] In summary, the current sensor housing and current sensor proposed in this utility model have the following advantages:

[0042] With its detachable, stackable housing units, users can freely increase or decrease the number of housing units according to their actual needs. This not only meets the requirements of single-channel current detection scenarios but also enables multi-channel synchronous monitoring by stacking multiple housing units, significantly improving the flexibility and space utilization of equipment deployment. The housing units are rigidly connected via connectors and protruding structures, simplifying the assembly process (disassembly and assembly can be completed without complex tools) while improving the overall structural stability of the assembled housing. This effectively solves the problems of low installation efficiency and difficult maintenance associated with traditional fixed housings.

[0043] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
