[0002] The non-contact three-phase phase detector adopts clamp-type non-contact measurement. There is no need to pull apart the wires or touch the high-voltage exposed live wires.

[0003] The inventor discovered during daily use of a contactless three-phase phase detector that the current connection between the connecting wire and the detector is fixed by a copper sheet inside the connection port. Due to the limited clamping force of the copper sheet, the connecting wire and the connection port are easily detached when the detector touches a high detection point, causing an impact. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and proposes an electric power indirect contact detection device.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an electric power non-direct contact detection device, including a detector, a display screen is arranged on the surface of the detector, an adjustment button is arranged on the surface of the detector, an anti-slip device is arranged on the upper top of the detector, a winding device is arranged on the side of the detector, an insulating clamp is arranged on the upper top of the detector, a connecting line is fixedly connected to one side of the insulating clamp, the anti-slip device includes a rectangular frame fixedly connected to the upper top of the detector, a card plate is slidably connected to the side of the rectangular frame, a rectangular plate is fixedly connected to the side of the card plate, a spring is fixedly connected to the side of the rectangular plate, the other end of the spring is fixedly connected to the side of the rectangular frame, and a conical block is fixedly connected to the surface of the connecting line.

When the detector needs to be used, the connecting wire and the connection port of the detector are fixed together through the anti-detachment device, and the insulating clamp is clamped on the cable that needs to detect electricity. The cable power information is collected by the insulating clamp and transmitted to the inside of the detector through the connecting wire for analysis and detection, and then the detection results are displayed on the display screen.

Under the action of the clamping ring, the connecting wire can be clamped and restricted inside the groove by the clamping ring after being inserted into the connecting port, thereby achieving the effect of preventing falling off.
[0013] Preferably, the winding device comprises an L-shaped rod fixedly connected to the side of the detector, and a limit strip is fixedly connected to the surface of the L-shaped rod.
[0014] The effect achieved by the above components is: under the action of the L-shaped rod, the connecting wire can be wrapped around the surface of the L-shaped rod, thereby achieving the effect of winding; under the action of the limit strip, the connecting wire will not be tangled on one side of the L-shaped rod, thereby achieving the effect of uniform winding.

[0020] The effects achieved by the above components are: under the action of the fixing ring, the insulating pliers can be fixed inside the elastic clamp, thereby achieving a fixing effect. After using the detector, the connecting wire is evenly wound around the surface of the L-shaped rod through the limit strip. After winding, the insulating pliers are clamped inside the elastic clamp. Under the action of the anti-sliding block, the insulating pliers will not be detached after being clamped inside the elastic clamp. Under the action of the fixing ring, the insulating pliers can be fixed inside the elastic clamp, thereby achieving a fixing effect, thereby achieving a winding effect.
[0021] Compared with the prior art, the advantages and positive effects of the utility model are:
[0022] In the utility model, an anti-dropping device is provided. When the connecting line needs to be prevented from dropping out, the connecting line is inserted into the connecting port. During the insertion process, the conical block fixed on the surface of the connecting line moves toward the inside of the rectangular frame, thereby squeezing the clamping plate to move to both sides. After the conical block is inserted into the rectangular frame, the clamping plate moves toward the middle under the action of the spring, thereby restricting the conical block inside the rectangular frame.
