Technical Field
[0001] This utility model relates to the field of explosion-proof electrical testing technology, and in particular to a quick-connect device for testing explosion-proof electrical parameters. Background Technology
[0002] Explosion-proof areas refer to areas in industrial production that are specially designed and maintained to prevent explosion accidents. These areas typically involve the handling or storage of flammable and explosive substances, such as chemicals, dust, or gases. Regularly checking the power parameters of explosion-proof areas is an important measure to ensure safety. During the power parameter check, the power cord needs to be connected to the explosion-proof electrical parameter testing equipment using a quick-connect device.
[0003] Currently, for explosion-proof electrical parameter testing, the common practice is to use a clamp to connect the power cord of the explosion-proof location to the wire connected to the explosion-proof electrical parameter testing equipment. However, this connection is prone to loosening and disconnection, requiring re-clamping and fixation, resulting in poor testing effectiveness. Utility Model Content
[0004] This disclosure relates to a quick-connect device for testing explosion-proof electrical parameters, which solves the problem that current explosion-proof electrical parameter testing operations generally use a clamp to connect the power cord of the explosion-proof location to the wire connected to the explosion-proof electrical parameter testing equipment. This connection is prone to loosening and disconnection, resulting in poor testing performance.
[0005] In a first aspect, this disclosure provides a quick-connect device for testing explosion-proof electrical parameters, specifically comprising: an insulating shell, a conductive element, metal beads, a movable ring, a plastic bolt, a detection wire, and a copper stop; the conductive element is installed inside the insulating shell, a power cord is plugged into the insulating shell, a slot is provided inside the conductive element, and the conductor of the power cord is plugged into the slot; four metal beads are installed inside the conductive element, and a spring is installed inside the insulating shell; a movable ring is fitted outside the insulating shell and connected to the conductive element; a plastic bolt is connected to one end of the conductive element, the plastic bolt is located outside the insulating shell, and a through hole is provided inside the plastic bolt; the detection wire passes through the through hole, and the outer insulation layer of the detection wire is in contact with the plastic bolt; a copper stop is connected inside the conductive element, the conductor of the detection wire is connected to the copper stop, and the end of the detection wire is connected to an explosion-proof electrical parameter testing device.
[0006] Furthermore, the conductive component has a threaded groove inside, the plastic bolt is threaded into the threaded groove, the copper stop is located in the threaded groove, the copper stop is in contact with the plastic bolt, and the copper stop is located between the plastic bolt and the conductive component.
[0007] Furthermore, the insulating shell has an inner inclined surface arranged in a circumferential shape inside, the conductive component is slidably connected inside the insulating shell, and the conductive component has an outer inclined surface arranged in a circumferential shape outside.
[0008] Furthermore, the conductive component has a through hole arranged in a circumferential shape on the outer inclined surface. The through hole is connected to the slot, and the metal bead moves in the through hole. One end of the metal bead is in contact with the inner inclined surface, and the other end of the metal bead is in contact with the conductor of the power line.
[0009] Furthermore, the spring is fitted outside the conductive component, with one end of the spring in contact with the inner wall of the insulating outer shell and the other end of the spring in contact with the outer wall of the conductive component.
[0010] Furthermore, the movable ring is slidably connected to the outside of the insulating shell, the outside of the insulating shell is provided with a movable hole, and a linkage rod is provided in a circumferential shape on the inner side of the movable ring, the linkage rod being slidably connected to the movable hole.
[0011] Furthermore, the conductive component is provided with a linkage groove in a circumferential shape on its exterior, and the end of the linkage rod is located inside the linkage groove.
[0012] This utility model provides a quick-connect device for detecting explosion-proof electrical parameters, which has the following advantages:
[0013] When in use, tightening the plastic bolt causes the copper stop to move inward, making it come into close contact with the conductive component. This ensures a good conductive connection between the conductive component and the detection wire, thereby guaranteeing the stability of the connection between the conductive component and the explosion-proof electrical parameter detection equipment.
[0014] Furthermore, when the power cord of the explosion-proof location to be measured is inserted into the insulating shell, the conductor of the power cord is inserted into the slot. The conductive component moves under the influence of the spring force, reducing the distance between the inner and outer inclined surfaces. The metal bead moves inward under the influence of the force, so that the metal bead contacts the conductor of the power cord, thereby clamping and fixing the power cord and ensuring the conductive connection between the power cord and the conductive component. Key power parameters such as phase voltage, line voltage, and frequency of the power cord in the explosion-proof location can then be collected by the explosion-proof electrical parameter detection equipment.
[0015] In addition, after the power cord in the explosion-proof area has been tested, the movable ring is moved in the opposite direction. The movable ring drives the conductive parts to move in the opposite direction synchronously. The distance between the inner and outer inclined surfaces increases, and the metal beads can move outward without obstruction. This allows the conductor of the power cord to be separated from the slot, making the power cord testing in the explosion-proof area simpler and faster.

[0030] This utility model discloses a quick-connect device for detecting explosion-proof electrical parameters, comprising: an insulating shell 1, a conductive element 2, metal beads 3, a movable ring 5, a plastic bolt 6, a detection wire 7, and a copper stop 8; the conductive element 2 is installed inside the insulating shell 1, and a power cord is plugged into the insulating shell 1; a slot 21 is provided inside the conductive element 2, and the conductor of the power cord is plugged into the slot 21; four metal beads 3 are installed inside the conductive element 2, and springs 4 are installed inside the insulating shell 1; a movable ring 5 is fitted outside the insulating shell 1 and is connected to the conductive element 2; a plastic bolt 6 is connected to one end of the conductive element 2, and the plastic bolt 6 is located outside the insulating shell 1, with a through hole 61 inside the plastic bolt 6; the detection wire 7 passes through the through hole 61. Inside, the outer insulation layer of the detection wire 7 contacts the plastic bolt 6; a copper stop 8 is connected inside the conductive component 2, and the conductor of the detection wire 7 is connected inside the copper stop 8. The end of the detection wire 7 is connected to the explosion-proof electrical parameter detection equipment; a threaded groove 25 is provided inside the conductive component 2, and the plastic bolt 6 is threaded into the threaded groove 25. The copper stop 8 is located inside the threaded groove 25 and contacts the plastic bolt 6. The copper stop 8 is located between the plastic bolt 6 and the conductive component 2; tightening the plastic bolt 6 causes the plastic bolt 6 to move the copper stop 8 inward, making the copper stop 8 in close contact with the conductive component 2, ensuring the conductive connection between the conductive component 2 and the detection wire 7, thereby ensuring the stability of the connection between the conductive component 2 and the explosion-proof electrical parameter detection equipment.
[0031] In this embodiment, the insulating shell 1 has an inner inclined surface 11 arranged in a circumferential shape inside, the conductive component 2 is slidably connected to the inside of the insulating shell 1, the conductive component 2 has an outer inclined surface 22 arranged in a circumferential shape outside, and a through hole 23 is arranged in a circumferential shape at the position of the outer inclined surface 22 of the conductive component 2. The through hole 23 communicates with the slot 21, the metal bead 3 moves in the through hole 23, one end of the metal bead 3 contacts the inner inclined surface 11, and the other end of the metal bead 3 contacts the conductor of the power line. The spring 4 is fitted on the outside of the conductive component 2, one end of the spring 4 contacts the inner wall of the insulating shell 1, and the other end of the spring 4 contacts the outer wall of the conductive component 2.
[0032] Using the above technical solution, when the power cord of the explosion-proof location to be measured is inserted into the insulating shell 1, the conductor of the power cord is inserted into the slot 21. The conductive element 2 moves under the influence of the spring 4, reducing the distance between the inner inclined surface 11 and the outer inclined surface 22. The metal bead 3 moves inward under the influence of the pushing force, so that the metal bead 3 contacts the conductor of the power cord, thereby achieving the effect of clamping and fixing the power cord and ensuring the conductive connection between the power cord and the conductive element 2. Thus, key power parameters such as phase voltage, line voltage, and frequency of the power cord in the explosion-proof location can be collected by the explosion-proof electrical parameter detection equipment.
[0033] In this embodiment of the present disclosure, the movable ring 5 is slidably connected to the outside of the insulating shell 1, the outside of the insulating shell 1 is provided with a movable hole 12, the inner side of the movable ring 5 is provided with a linkage rod 51 in a circumferential shape, the linkage rod 51 is slidably connected to the movable hole 12, the outside of the conductive component 2 is provided with a linkage groove 24 in a circumferential shape, and the end of the linkage rod 51 is located in the linkage groove 24.
[0034] Using the above technical solution, after the power cord test in the explosion-proof area is completed, the movable ring 5 moves in the opposite direction. The movable ring 5 drives the conductive part 2 to move in the opposite direction synchronously. The distance between the inner inclined surface 11 and the outer inclined surface 22 increases, and the metal bead 3 moves outward without obstruction. This allows the conductor of the power cord to be separated from the slot 21, making the power cord test in the explosion-proof area simpler and faster.
[0035] The working principle of this embodiment is as follows: First, tighten the plastic bolt 6. The plastic bolt 6 drives the copper stop 8 to move inward, making the copper stop 8 in close contact with the conductive part 2, ensuring the connection effect between the conductive part 2 and the explosion-proof electrical parameter detection equipment. Next, insert the power cord of the explosion-proof location to be measured into the insulating shell 1. The conductor of the power cord is inserted into the slot 21. The conductive part 2 moves under the influence of the spring 4, reducing the distance between the inner inclined surface 11 and the outer inclined surface 22. The metal bead 3 moves inward under the influence of the pushing force, making the metal bead 3 contact the conductor of the power cord, thus clamping and fixing the power cord. The key power parameters such as phase voltage, line voltage, and frequency of the power cord in the explosion-proof location can then be collected by the explosion-proof electrical parameter detection equipment. Finally, move the movable ring 5 in the opposite direction. The movable ring 5 drives the conductive part 2 to move in the opposite direction synchronously. The distance between the inner inclined surface 11 and the outer inclined surface 22 increases, and the metal bead 3 moves outward without obstruction. This separates the conductor of the power cord from the slot 21, making the power cord detection in the explosion-proof location simpler and faster.
