Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0035] like Figure 6-8The figure shows an existing cable clamp. This clamp includes two upwardly and inwardly curved clamping grooves 311 on either side of the clamp body 31, and two hinged pressure blocks 32 disposed between the two clamping grooves 311. Each clamping groove 311 and its corresponding pressure block 32 clamp a wiring harness 4. This clamp serves only as a mechanical connection for the wiring harness 4 and cannot monitor current status. This requires the installation of a transformer or clamp meter, which requires the wiring harness 4 to be removed from the parallel-groove clamp, increasing cost and complexity. Manual inspections or offline measurements result in data lag, making it difficult to detect overloads or poor contact issues in a timely manner.

[0036] Example 1

[0037] like Figure 1-Figure 5 As shown, an embodiment of the present invention provides a current detection device for a wire clamp, which is used to clamp a wire harness 4. The current detection device includes a clamping component and a detection component. The clamping component includes two clamping blocks 11 hinged at one end, a locking unit 12 arranged between the other ends of the two clamping blocks 11, and a fixing unit 13 arranged on the wire clamp so that any of the clamping blocks 11 can be detached. The wire harness 4 is passed between the two clamping blocks 11. The detection component includes a current sensor, a signal processing circuit and a data output unit. The current sensor, signal processing circuit and data output unit are integrated on at least one of the clamping blocks 11.

[0038] The current detection device of this embodiment includes a clamping assembly and a detection assembly. The clamping assembly is composed of two hinged clamping blocks 11, a locking unit 12 and a fixing unit 13. The detection assembly integrates a current sensor, a signal processing circuit and a data output unit on the clamping block 11.

[0039] The current detection device of the present invention utilizes an integrated design, integrating current monitoring functionality directly into the clamp structure. This eliminates the need for additional sensors, reducing device complexity and cost. The current detection device of the present invention enables real-time monitoring, collecting current data in real time through embedded sensors, improving monitoring efficiency. The current detection device of the present invention utilizes modular installation, with a removable clamp block 11 for easy maintenance and replacement.

[0040] In addition, the clamping block 11 can adopt a split structure to adapt to wire harnesses 4 of different diameters; the detection component can support multiple sensor interfaces and be compatible with different monitoring requirements.

[0041] Specifically, the output end of the current sensor is electrically connected to the signal processing circuit;

[0042] The signal processing circuit is arranged inside the clamp 11 and may include a filtering circuit and an amplifying circuit for conditioning the signal of the current sensor; the data output unit is connected to the signal processing circuit and is used to output the processed current data through a wired or wireless transmission module.

[0043] In some embodiments, the current sensor is a Rogowski coil or a Hall sensor.

[0044] The current sensor of the current detection device of this embodiment is a Rogowski coil or a Hall sensor. The Rogowski coil is suitable for high-frequency and high-current scenarios, while the Hall sensor is suitable for low-current and compact spaces, meeting diverse needs. Non-invasive measurement is achieved, and both sensors do not need to damage the wires to avoid introducing contact resistance. Hybrid sensor configurations (such as Rogowski coil + Hall sensor) are supported to cover a wider current range.

[0045] The sensor of this embodiment can be calibrated to adapt to different wire materials (such as copper, aluminum).

[0046] In some embodiments, each of the clamping blocks 11 has a semicircular groove 111 adapted to the wiring harness 4. When the current sensor is a Rogowski coil, the coil of the Rogowski coil includes two semicircular spiral coils 21. The two semicircular spiral coils 21 are respectively arranged in the semicircular grooves 111 of the two clamping blocks 11. When the two clamping blocks 11 are buckled together, the two semicircular spiral coils 21 can be assembled to form a spiral coil.

[0047] In this embodiment, the Rogowski coil consists of two semicircular spiral coils 21 embedded in a semicircular groove 111 of the clamping block 11, forming a complete spiral coil when fastened together. The closed coil structure of this embodiment ensures the integrity of current measurement and reduces magnetic flux leakage interference. The split coil design facilitates the opening and closing of the clamping block and allows installation without removing the wires.

[0048] When a Rogowski coil is used, the Rogowski coil includes two semicircular spiral coils 21, which are respectively embedded in the semicircular grooves 111 of the two clamping blocks 11. The ends of the two semicircular spiral coils 21 form a closed loop when the clamping blocks 11 are buckled together through conductive connectors.

One end of the other clamping block 11 has a protrusion 113 located between the two lugs 112, and the protrusion 113 has a first rotating shaft 1131 inserted into the insertion hole 1121.

[0054] In this embodiment, the clamping block 11 is hinged by the lug 112 , the protrusion 113 and the first rotating shaft 1131 , and has good mechanical stability. The hinged structure enhances the clamping force and prevents the wire harness from loosening.

[0056] In some embodiments, the locking unit 12 includes a second rotating shaft 121, a locking screw 122, a locking nut 123, and two locking base plates 124 constructed at the other end of the two clamping blocks 11. The two locking base plates 124 are each provided with a U-shaped groove 1241 with an opening facing away from the clamping block 11. Two opposite side walls of the U-shaped groove 1241 of any locking base plate 124 are provided with second insertion holes 1121. The second rotating shaft 121 is inserted into the second insertion hole 1121 and is connected to the locking screw 122. The locking nut 123 is locked to the locking screw 122 and is located on the side of the other locking base plate 124 facing away from the second rotating shaft 121.

[0057] The locking screw 122 is inserted into the U-shaped grooves 1241 of the two locking base plates 124 .

[0058] In this embodiment, the locking unit 12 is fastened using a U-shaped groove 1241, a locking screw 122, and a locking nut 123. The locking screw 122 and the locking nut 123 cooperate to achieve one-handed operation, thereby improving installation efficiency.

[0059] The locking unit 12 may be provided with an anti-loosening washer to prevent the locking nut 123 from falling off due to vibration.

[0061] In this embodiment, the fixing unit 13 secures the clamping block 11 to the wire clamp via a baffle 131, a locking bolt 132, and a locking seat 133. This ensures reliable fixation of the current detection device: the locking bolt 132 and the locking seat 133 provide multi-point fixation, preventing the device from shifting. The fixing unit 13 of this embodiment is highly adaptable and can accommodate different types of wire clamps, providing high versatility.

[0062] The locking seat 133 can be designed as a rotatable structure to adapt to different installation angles; the surface of the baffle 131 can be increased with anti-slip textures to improve friction.

[0063] Specifically, the locking bolt 132 passes through the through hole 1311 of the baffle 131 and is screwed into the locking hole 1331 of the locking seat 133 , so that the clamping block 11 and the wire clamp body 31 form a detachable connection.

[0069] The energy storage capacitor is connected to the output end of the inductive power unit to smooth the power output; the voltage conversion circuit converts the inductive power or battery voltage into the working voltage of the detection component.
