[0004] However, the types of installation connectors of existing power detectors are complex, and the installation methods of contacts on different electrical equipment in the same distribution cabinet are also different. This requires engineers to install connectors according to the contacts at the detection points for the designated wiring terminals on the wiring harness when performing power detection, resulting in inconvenience in use.

[0005] Based on this, the utility model designs a multifunctional connector for power quality detection to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a multifunctional connector for power quality detection to solve the above technical problems.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: comprising a connecting wire, one end of which is fixedly provided with a connecting joint, a mounting block is fixedly provided on the connecting wire, a connecting sheet is fixedly provided on the mounting block, the other end of the connecting wire is fixedly provided on the connecting sheet, a contact hole is provided on the mounting block, the contact hole is provided on a side of the mounting block away from the connecting joint, a movable block is rotatably provided on the mounting block; a yield hole is provided on the movable block, a branch line is fixedly provided in the yield hole, a detection joint is fixedly provided on the branch line, a spring is sleeved on the branch line, the spring is located on a side of the branch line away from the detection joint, the spring is fixedly provided on the movable block, a contact ball is fixedly provided on the other end of the branch line, the contact ball is fixedly provided on the spring, the contact ball is placed in the contact hole, and the contact ball abuts against the connecting sheet; a plurality of yield holes are provided.

[0008] By adopting the above technical solution, when a different detection joint needs to be used, it is only necessary to rotate the movable block so that the contact ball corresponding to the detection joint contacts the connecting piece, thereby achieving the purpose of quickly replacing the detection joint.

[0009] Preferably, insulating material is sprayed on the spring.

[0010] By adopting the above technical solution, it is avoided that the springs in the movable block contact each other, causing the idle detection connector to be connected to the connecting piece, resulting in abnormal detection results.

[0011] Preferably, a contact block is fixedly provided on the contact ball, and the contact block abuts against the connecting sheet.

[0012] By adopting the above technical solution, the contact area between the contact ball and the connecting piece is increased, so that the transmission effect of the connecting line is improved.

[0013] Preferably, a guide groove is provided on the contact hole, and a plurality of guide grooves are provided.

[0014] By adopting the above technical solution, when the movable block is rotated, the contact ball can be smoothly disengaged from the clearance hole to avoid affecting the rotation of the movable block.

[0015] Preferably, a support block is fixedly provided on the movable block, and the spring is placed in the support block.

[0016] By adopting the above technical solution, the spring is restricted in the supporting block during the rotation of the movable block, thereby preventing the springs from being entangled with each other after deformation, thereby preventing damage to parts.

[0017] In summary, the present application has the following beneficial technical effects: through the setting of the movable block, different detection connectors are set on the movable block.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The following is combined with Figure 1 —4 Provide further details of this application.

[0027] A multifunctional connector for detecting power quality comprises a connecting wire 1; a connecting connector 2 is fixedly arranged at one end of the connecting wire 1.

[0028] A mounting block 3 is fixedly arranged on the connecting wire 1, a connecting piece 4 is fixedly arranged on the mounting block 3, and the other end of the connecting wire 1 is fixedly arranged on the connecting piece 4; a contact hole 5 is opened on the mounting block 3, and the contact hole 5 is opened on the side of the mounting block 3 away from the connecting joint 2, and a guide groove 6 is opened on the contact hole 5, and two guide grooves 6 are opened; a movable block 7 is rotatably arranged on the mounting block 3.

[0029] The movable block 7 is provided with a clearance hole 8 , in which a branch line 9 is fixedly arranged, and a detection joint 10 is fixedly arranged on the branch line 9 ; the movable block 7 is fixedly provided with a support block 11 .

[0030] A spring 12 is sleeved on the branch line 9, and an insulating material is sprayed on the spring 12; the spring 12 is placed in the support block 11; the spring 12 is located on the side of the branch line 9 away from the detection joint 10, and the spring 12 is fixedly set on the movable block 7, and a contact ball 13 is fixedly set on the other end of the branch line 9, and the contact ball 13 is fixedly set on the spring 12; a contact block 14 is fixedly set on the contact ball 13, and the contact ball 13 is placed in the contact hole 5, and the contact block 14 abuts against the connecting piece 4; a plurality of clearance holes 8 are provided.

[0031] The implementation principle of this embodiment is as follows: when in use, the connecting joint 2 is plugged into the detection device, and then after selecting the appropriate detection joint 10, the movable block 7 is rotated to offset the position of the support block 11 and the mounting block 3; when the movable block 7 is rotated, the contact ball 13 placed in the contact hole 5 is driven by the support block 11, and moves along the guiding action of the guide groove 6 toward the direction close to the support block 11, and squeezes the spring 12; until the contact ball 13 is completely out of contact with the contact hole 5, at which time the connecting joint 2 is disconnected from the detection joint 10; the movable block 7 is continued to be rotated, so that the contact ball 13 connected to the appropriate detection joint 10 moves toward the contact hole 5, and in the process of approaching the connecting piece 4 along the guide groove 6, the spring 12 rebounds and stretches to push the contact ball 13 close to the connecting piece 4, until the contact block 14 is pressed against the connecting piece 4, at which time the appropriate detection joint 10 is connected to the connecting joint 2 for detection.

[0032] By setting the movable block 7, different detection connectors 10 are set on the movable block 7. When a specific detection connector 10 is needed, the purpose of replacing the detection connector 10 can be achieved by simply rotating the movable block 7 so that the contact block 14 on the specific detection connector 10 contacts the connecting piece 4. This has the advantage of being easy to use.
