[0058] The following is a clear and complete description of the technical solution of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0059] like Figure 1 As shown, an embodiment of the present application provides a current detector 100, which includes a substrate 1, an adapter 2, and a current measuring component 3. The substrate 1, the adapter 2, and the current measuring component 3 do not need to be connected by cables, thereby improving the stability of signal transmission.

[0060] like Figure 2 As shown, the substrate 1 includes a first housing 11, a processing module 12 and a first contact 13, and the processing module 12 and the first contact 13 are both arranged in the first housing 11. Optionally, the processing module 12 includes an integrator and an analog-to-digital conversion module, which can process the detected signal. The first contact 13 is communicatively connected with the processing module 12, and the first contact 13 can transmit the signal to the processing module 12.

[0061] The adapter 2 includes a second shell 21 and a second contact 22, and the second contact 22 is disposed in the second shell 21. The second shell 21 is detachably connected to the first shell 11, and when the second shell 21 is connected to the first shell 11, the second contact 22 can abut against the first contact 13. For example, the top of the first shell 11 is provided with an opening, and the adapter 2 is inserted into the top opening of the first shell 11, the second shell 21 is connected to the first shell 11, and the second contact 22 abuts against the first contact 13.

[0062] The current measuring component 3 is connected to the adapter 2 in an abutting manner, at least one end of the current measuring component 3 is detachably connected to the adapter 2, and the current measuring component 3 is in communication connection with the second contact 22. The current measuring component 3 is used to detect the current signal of the measured conductor, and the signal detected by the current measuring component 3 is transmitted to the processing module 12 through the second contact 22 and the first contact 13. The processing module 12 is used to process the signal output by the current measuring component 3. For example, the processing module 12 is used to integrate, convert analog to digital, and perform parameter correction processing on the signal output by the current measuring component 3. Optionally, the current measuring component 3 is a Rogowski coil or a Hall effect sensor, the Rogowski coil is used to measure AC current signals, and the Hall effect sensor is used to measure DC or AC current signals.

[0063] The first contact 13 and the second contact 22 described above, as key components for circuit connection or signal transmission, are not limited to specific types in their specific forms. They can be probe-type contacts, which usually have a sharp tip and can accurately penetrate the object to be measured or the connection point to achieve precise electrical connection. At the same time, they can also be contact-type contacts, which are often designed as a plane or curved structure to establish an electrical connection by directly contacting the target surface. Regardless of the contact method adopted, the main purpose of the first contact 13 and the second contact 22 is to achieve a stable and reliable electrical connection, thereby ensuring the normal operation of the circuit or the accurate transmission of the signal. In one embodiment, one end of the current measuring part 3 is non-detachably connected to the adapter 2, and the other end of the current measuring part 3 is detachably connected to the adapter 2. In another embodiment, both ends of the current measuring part 3 are detachably connected to the adapter 2.

[0064] The base 1 , the adapter 2 and the current measuring component 3 of the current detector 100 of the present embodiment are connected by abutment, thus avoiding the use of flexible cables and improving the stability and reliability of signal transmission.

[0065] Conventional flexible cables are prone to damage or breakage when frequently bent, stretched or twisted, which affects the service life and reliability of the current detector.

[0068] The clamping portion 233 is slidably disposed in the first through hole 2321. After the clamping portion 233 is inserted into the first through hole 2321, one end of the clamping portion 233 is located outside the first through hole 2321. A clamping claw 2333 is provided at the end of the clamping portion 233 located outside the first through hole 2321. The number of the clamping claws 2333 is multiple, and the clamping claws 2333 can be retracted toward the axis of the clamping portion 233. The end of the current measuring member 3 can be inserted into the clamping portion 233. The side wall of the clamping portion 233 is provided with a clamping hook 2331 that is compatible with the clamping groove 2312 of the support portion 231.

The top of the inner wall of the through hole of the nut 234 is flared, and the nut 234 is rotated, and the nut 234 moves toward the direction close to the support part 231, and the nut 234 squeezes the clamping jaw 2333, and the clamping jaw 2333 shrinks toward the axis of the clamping part 233 to clamp the end of the current measuring member 3.

[0070] Insert the clamping part 233 into the first through hole 2321 of the plug-in part 232, and the clamping hook 2331 passes through the clamping sliding hole 2322. Insert the plug-in part 232 into the plug-in hole 2311 of the support part 231, and the clamping hook 2331 is clamped into the clamping slot 2312, thus completing the connection between the end of the current measuring part 3 and the adapter 2.

[0071] like Figure 4As shown, optionally, a fixing hole 2313 is provided at the end of the support portion 231 away from the plug hole 2311. A clamping structure 23 is provided on the second housing 21, and the fixed end of the current measuring member 3 is inserted into the fixing hole 2313 of the support portion 231 and is non-detachably connected to the support portion 231. The fixed end of the current measuring member 3 is communicatively connected with the second contact 22. The movable end of the current measuring member 3 is inserted into the clamping portion 233, and the movable end of the current measuring member 3 is clamped in the clamping portion 233. The clamping hook 2331 of the clamping portion 233 passes through the clamping sliding hole 2322 of the plug-in portion 232, and the plug-in portion 232 and the clamping portion 233 are integrally connected to the support portion 231 in a detachable manner.

[0072] The movable end of the current measuring member 3 is connected to the clamping portion 233. When measuring the wire, the plug-in portion 232 is inserted into the plug-in hole 2311, and the current measuring member 3 forms a measuring ring. The distance between the movable end and the fixed end of the current measuring member 3 is very small, for example, 1 to 3 mm, which can improve the measurement accuracy of the current measuring member 3. For different measured wires, the adapter 2 and the current measuring member 3 can be replaced at the same time without replacing the base 1.

[0073] After completing the measurement of the conductor, the clamping portion 233 is pushed toward the fixing hole 2313 , and the clamping hook 2331 abuts against the hole wall of the clamping sliding hole 2322 and then contracts toward the axis of the clamping portion 233 , and the clamping hook 2331 disengages from the clamping slot 2312 , and the plug-in portion 232 can be pulled out of the plug-in hole 2311 .

[0074] like Figure 5 As shown, in some embodiments, the plug-in portion 232 includes a large diameter portion 2323 and a small diameter portion 2324 connected to each other, and the clamping slide hole 2322 is located in the small diameter portion 2324. The small diameter portion 2324 can enter the plug-in hole 2311, and the outer diameter of the large diameter portion 2323 is larger than the hole diameter of the plug-in hole 2311. The shoulder between the large diameter portion 2323 and the small diameter portion 2324 can abut against the end surface of the support portion 231 to limit the plug-in portion 232 from being excessively inserted into the plug-in hole 2311.

[0075] Optionally, a positioning groove 2314 is provided on the hole wall of the plug hole 2311 , and a positioning column 2325 is provided on the outer wall of the small diameter portion 2324 . The positioning column 2325 is matched with the positioning groove 2314 to facilitate repeated positioning of the plug-in portion 232 and the support portion 231 .

[0076] Optionally, the end of the current measuring component 3 may be detachably connected to the adapter 2 by means of threads or magnetic adsorption.

[0077] like Figure 6As shown, both ends of the current measuring member 3 are detachably connected to the adapter 2. For example, two adapters are provided on the second housing 21, one end of the current measuring member 3 is magnetically connected to the first adapter 241, and the other end of the current measuring member 3 is magnetically connected to the second adapter 242. The first adapter 241 is connected to the second contact 22 via a cable so that the current measuring member 3 can be connected to the second contact 22.
