[0024] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.

[0025] Seen in Figure 1-7 This embodiment provides a Rogowski coil connector assembly, which includes a Rogowski coil body 1 and an assembly housing 2. The assembly housing 2 includes a first housing 21 and a second housing 22 that are mated together to form a mating cavity 23. The assembly housing 2 has a fixed connection hole 24 and a movable connection hole 25 on both sides in the width direction for inserting both ends of the Rogowski coil body 1. A mating connector 3 is provided at the end of the Rogowski coil body 1 that is inserted into the movable connection hole 25. A limiting member 4 that moves in the width direction is provided in the mating cavity 23. A mating groove 31 is formed on the side wall of the mating connector 3. The limiting member 4 is used to abut against the mating groove 31 after the mating connector 3 is inserted into the movable connection hole 25.

[0026] According to the solution provided in this embodiment, one end of the Rogowski coil body 1 is inserted into the fixed connection hole 24 and fixedly connected to the component housing 2, and the other end is detachably connected to the movable connection hole 25. By inserting the mating connector 3, the limiting member 4 is mated with the mating groove 31, thereby achieving a fixed mating between the end of the Rogowski coil body 1 near the mating connector 3 and the component housing 2, and thus enabling the Rogowski coil body 1 to be wound around the cable to be tested. When it is necessary to remove the Rogowski coil body 1, it is only necessary to separate the limiting member 4 from the mating groove 31, so that the Rogowski coil body 1 can be pulled out of the movable connection hole 25.

[0027] Furthermore, the mating connector 3 includes an integrally formed insertion part 32 and abutment part 33, both of which are cylindrical. The diameter of the insertion part 32 is smaller than that of the abutment part 33. A mating groove 31 is formed in the insertion part 32. In use, when it is necessary to install a Rogowski coil, the insertion part 32 is inserted into the movable connection hole 25, and the abutment part 33 abuts against the movable connection hole 25.

[0028] In this embodiment, the first housing 21 forms a first mounting groove 211 along its width direction. The first mounting groove 211 is used to slide with the limiting member 4. The limiting member 4 is provided with a first spring 5 on the side near the first mounting groove 211. The first spring 5 is used to keep the limiting member 4 away from the first mounting groove 211. A button 44 is provided at the end of the limiting member 4 away from the mating hole 42. A through guide hole 221 is provided at the second housing 22. The guide hole 221 slides with the button 44. A mating cover 222 is rotatably provided on the side of the second housing 22 located at the guide hole 221. The mating cover 222 is used to cover the button 44, thereby preventing accidental activation of the button 44 during use.

[0029] In use, when the mating connector 3 needs to be mated with the limiting member 4, press button 44 to make the limiting member 4 compress the first spring 5. At this time, insert the insertion part 32 of the mating connector 3 into the movable connecting hole 25. When the abutting part 33 abuts against the movable connecting hole 25, release button 44 to make the limiting member 4 abut against the mating groove 31, so as to achieve a fixed mating between the mating connector 3 and the limiting member 4. At this time, the first spring 5 is compressed. When the mating connector 3 needs to be separated from the limiting member 4, press button 44 to separate the limiting member 4 from the mating groove 31 of the mating connector 3, and the mating connector 3 can be pulled out.

[0030] The limiting component 4 includes a component body 41, one end of which forms a mating hole 42 for mating with the first spring 5, and a mating strip 43 formed on the side wall of the component body 41 for inserting into the mating groove 31.

[0031] In this embodiment, the Rogowski coil body 1 includes a wire 11, and a first silicone tube 12 is sleeved on the outer wall of the wire 11. A spiral coil 13 is provided on the outer wall of the first silicone tube along the length direction. One end of the spiral coil 13 near the abutment part 33 is connected to the wire 11. A second silicone tube 14 is also provided on the outer wall of the first silicone tube 12. The second silicone tube 14 is used to wrap the spiral coil 13.

[0032] The insertion part 32 is provided with a second mounting groove 321 at the end away from the abutment part 33. A circular circuit board 323 is provided at the second mounting groove 321. A first wire hole 322 for the wire 11 to pass through is formed at the bottom of the second mounting groove 321. The wire 11 is welded to the circuit board 323 to achieve a fixed fit between the Rogowski coil body 1 and the mating connector 3.

[0033] Furthermore, a spring mounting groove 212 is provided at the first housing 21, and a second spring 6 is provided at the mounting groove. The second spring 6 is used to keep the mating joint 3 away from the spring mounting groove 212. A fixing groove 213 is provided below the spring mounting groove 212. The fixing groove 213 is used to fix the Rogowski coil body 1 away from the mating joint 3.

[0034] The second spring 6 can push the mating joint 3 to move away from the spring mounting groove 212 when the mating joint 3 is separated from the limiting member 4, thereby facilitating the separation of the limiting member 4 from the movable mounting hole.

[0035] In this embodiment, the bottom of the component housing 2 is provided with a second wire hole 26, and a lead wire 15 is provided at the second wire hole 26. The lead wire 15 is connected to the wire 11, thereby better realizing the transmission of the current signal at the Rogowski coil body 1 to the measuring device for processing and analysis.

[0036] Working principle:

[0037] Once the cable to be measured is determined, bring the component housing 2 close to the cable and wrap the Rogowski coil body 1 around it, so that the cable is in the loop of the Rogowski coil. Press and hold button 44 and insert the insertion part 32 of the mating connector 3 into the movable connection hole 25. When the abutting part 33 abuts against the movable connection hole 25, release button 44, so that the mating strip 43 is inserted into the mating groove 31, thereby achieving a fixed fit between the mating connector 3 and the limiting member 4. Then rotate the mating cover 222 to cover button 44, thereby completing the installation of the Rogowski coil. When it is necessary to remove the Rogowski coil, first turn the mating cover 222 to expose button 44, then press button 44 to separate the mating connector 3 from the limiting member 4, and then pull the mating connector 3 out of the movable connection hole 25 to remove the Rogowski coil.

[0038] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the embodiments shown are only part of the embodiments of the present invention. The actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
