[0037] The present application provides Figures 1-7The utility model discloses a kind of wire clamps for track type electric energy meter detection device, including left handle 1 and the right handle 2 of being set in left handle 1 right side;

[0038] The sleeve 3 is arranged in the left side of the right handle 2, and the sleeve 3 is arranged in the center of the left handle 1 and the right handle 2. The left handle 1 and the right handle 2 are connected by the sleeve 4, and the left handle 1 can rotate outside the sleeve 3 through the sleeve 4.

[0039] The lower end of the right handle 2 is provided with a connecting line 13, and the end of the connecting line 13 is provided with a connecting plug 14. The end of the connecting plug 14 is provided with a plug rod 15, and an anti-loosening structure is arranged outside the plug rod 15. The anti-loosening structure includes an elastic claw arranged inside the plug rod 15 and an annular clamping groove arranged on the outer wall of the plug rod 15. The elastic claw is clamped into the annular clamping groove of the port of the detection equipment, ensuring the stability of the connection and avoiding the interruption of the connection caused by accidental pulling during the detection process, so as to ensure the stable transmission of the electric energy data to the detection equipment.

[0040] The top of the left handle 1 and the right handle 2 is provided with a metal clamp 5, which is made of copper alloy material with high conductivity and is coated with an anti-oxidation layer.

[0041] The connecting line 13 penetrates the inner groove 7 of the right handle 2, and the inner side of the two metal clamps 5 is provided with a plurality of meshing grooves 6. The connecting line 13 is connected to the metal clamp 5 by welding connection. The inner side of the left handle 1 and the right handle 2 is provided with an inner groove 7.

[0042] In this embodiment, when the user uses the wire clamp device for track type electric energy meter detection, it is first connected with the detection equipment and the track type electric energy meter. The specific operation is to pick up the device, accurately align the connecting plug 14 and the plug rod 15 at the lower end of the connecting line 13 of the right handle 2 with the corresponding connecting port of the detection equipment, and insert them with force. The elastic claw of the anti-loosening structure outside the plug rod 15 is clamped into the annular clamping groove of the port of the detection equipment, realizing stable physical connection and reliable electrical conduction with the detection equipment.

[0043] Subsequently, the metal clamp 5 is connected to the wiring terminal of the track type electric energy meter, and the left handle 1 and the right handle 2 are rotated around the sleeve 4, so that the plurality of meshing grooves 6 on the inner side of the metal clamp 5 tightly fit the surface of the electric energy meter wiring terminal. Since the metal clamp 5 is made of copper alloy material with high conductivity and is coated with an anti-oxidation layer, the contact resistance is reduced. This tight fit can ensure that the metal clamp 5 and the wiring terminal form a good electrical connection, so that the electric signals such as current and voltage of the electric energy meter can be smoothly conducted to the metal clamp 5.

[0044] When the wiring clamp is connected with the detection equipment and the electric energy meter, the detection process is formally started. The electric current, voltage and other electric signals generated by the electric energy meter in the running process are conducted to the connecting wire 13 through the metal clamp 5. The connecting wire 13 is composed of multiple soft copper wires and wrapped with an insulating rubber sleeve, has good conductivity and anti-interference ability, and stably transmits the electric signals to the connecting plug 14 and the plug rod 15, and then to the detection equipment. The detection equipment internally pre-sets various detection programs and standard parameters, and can collect, analyze and process the received electric signals. For example, the detection equipment compares the difference between the electric signal parameters and the standard parameters to judge the accuracy of the electric energy meter measurement, the stability of the running and other performance indicators. If abnormalities are found during the detection process, the detection equipment will feedback to the operator through the display device, alarm device and the like, so as to timely repair or debug the electric energy meter.

[0045] During the whole detection process, the components of the wiring clamp device work cooperatively. The metal clamp 5 is responsible for efficient collection of electric energy meter electric signals, the connecting wire 13 guarantees stable signal transmission, and the connecting plug 14 and the plug rod 15 realize reliable connection with the detection equipment.

[0046] As shown in Figures 1-5 , the outer part of the extension sleeve 8 is wrapped with a rubber pad, and the front and rear sides of the extension sleeve 8 are provided with round corners. The connecting wire 13 is composed of multiple soft copper wires and wrapped with an insulating rubber sleeve.

[0047] Optionally, during the whole detection process, the left clamp handle 1 and the right clamp handle 2 are integrally formed by high-strength engineering plastic, have good insulation performance, and prevent the operator from being electrocuted. The connecting wire 13 composed of multiple soft copper wires and wrapped with an insulating rubber sleeve has good flexibility and wear resistance, is convenient for wiring and use in complex environments, and provides all-round protection for the smooth progress of the detection work.

[0048] As shown in Figures 1-7 , the inner part of the left clamp handle 1 and the right clamp handle 2 is provided with a sliding groove 16. The front and rear ends of the sliding groove 16 are respectively provided with sliding rail blocks 12. The outer side of the sliding rail block 12 is provided with an extension sleeve 8. The inner side of the extension sleeve 8 and the sliding rail block 12 is provided with a sleeve block 11.

[0049] The top inner side of the extension sleeve 8 is provided with a fixed screw rod 9, and the top outer side of the fixed screw rod 9 is provided with a fixed nut 10. The plurality of sliding rail blocks 12 are connected with the left clamp handle 1 and the right clamp handle 2 by bolt connection. The sleeve block 11 is fixedly connected with the extension sleeve 8. The sleeve block 11 is connected with the sliding rail block 12 by sleeve embedding connection. The extension sleeve 8 can move in the sliding rail block 12 through the sleeve block 11. The fixed screw rod 9 penetrates the sliding groove 16 and the extension sleeve 8. The fixed nut 10 is connected with the fixed screw rod 9 by thread connection, and is pressed on the outer part of the extension sleeve 8.

[0050] Preferably, when different sizes of track-type electric energy meter need to be detected, the clamping range of the clamping handle can be adjusted according to the position and size of the electric energy meter terminal. Loosen the fixing nut 10, at this time the fixing effect of the fixing screw 9 on the extension sleeve 8 is released, and the extension sleeve 8 can move freely in the sliding rail block 12 through the sleeve block 11. The scale mark at the bottom of the sliding groove 16 can assist the operator to accurately control the movement distance of the extension sleeve 8. After adjusting to the appropriate length, tighten the fixing nut 10, and the fixing screw 9 holds the fixing nut 10 outside the extension sleeve 8, and the extension sleeve 8 is firmly fixed in the sliding groove 16. The rubber pad wrapped outside the extension sleeve 8 increases the friction force with the operator's hand, making it easy to hold, and also serves as a buffer to improve the operation feel. The rounded design on both sides of the extension sleeve 8 can prevent scratching the operator during operation.

[0051] After adjusting the clamping handle, the electric energy meter can be clamped. The operator holds the extension sleeve 8 with both hands, rotates the left clamping handle 1 and the right clamping handle 2 around the sleeve shaft 4, and makes the metal clamp 5 close to the terminal of the track-type electric energy meter. The multiple engagement grooves 6 on the inner side of the metal clamp 5 can match the shape of the terminal, increase the contact area, achieve tight clamping, effectively reduce the contact resistance, ensure the stability and accuracy of electric energy transmission, and avoid the influence of poor contact on the detection result. The connecting wire 13 is connected with the metal clamp 5 by welding, and penetrates the inner groove 7 of the right clamping handle 2, ensuring that electric energy can be smoothly transmitted from the metal clamp 5 to the detection equipment.
