【Introduction of the new patent】A patch cord device for electric energy meter detection

Today, I will introduce a national invention authorized patent-a patch cord device for electric energy meter detection. The patent was applied for by the Electric Power Research Institute of Yunnan Power Grid Co., Ltd., and the authorization was announced on February 9, 2018.

The invention relates to the technical field of electric energy meter detection, in particular to a patch cord device for electric energy meter detection.

When testing the electric energy meter, it is necessary to contact the probe with the voltage and current terminals of the electric energy meter and the signal auxiliary terminal. Each probe corresponds to a terminal. The process of contacting the above-mentioned probe with various electric energy meter terminals is called electric meter connection. barge. After the electric meter is connected, various tests are performed on the electric energy meter. In the prior art, the number and arrangement of the terminals of different types of electric energy meters are generally different. The plug-in wiring device is generally designed according to the specific electric energy meter, and the versatility is not strong. .

In view of this, overcoming the above-mentioned defects in the prior art and providing a new patch cord device for electric energy meter detection has become a technical problem to be solved urgently in this field.

The purpose of the present invention is to provide a patch cord device for the detection of electric energy meters in view of the above-mentioned defects of the prior art.

The figure is a schematic diagram of the structure of the present invention

The technical solution adopted by the present invention is: the present invention provides a patch cord device for electric energy meter detection, including: a first detection component opposite to the voltage and current terminals of the electric energy meter; and opposite to the auxiliary signal terminal of the electric energy meter And a fixing part for supporting the detection part, the fixing part includes a bottom fixing block for supporting the first detection part, a middle fixing block provided on the bottom fixing block for supporting the second detection part, And a top fixed block slidably arranged on the middle fixed block for supporting the second detection part; the first detection part includes a first outer sleeve mounted on the fixed part and a first outer sleeve contained in the first outer sleeve and removed from the first outer sleeve The sleeve extends to contact the first contact end of the voltage and current terminal of the electric energy meter. The first contact end can move back and forth toward or away from the electric energy meter with respect to the first outer sleeve; the second detection component includes a fixed component installed The second outer sleeve is contained in the second outer sleeve and extends from the second outer sleeve to contact the second contact end of the auxiliary signal terminal of the electric energy meter, and the tip telescopic portion provided at the second contact portion .

Preferably, both ends of the bottom fixing block are respectively provided with a first mounting structure, and both ends of the middle fixing block are respectively provided with a second mounting structure that matches the first mounting structure. The middle fixing block is provided with a fixing plate extending vertically downward from the rear surface of the middle fixing block and matched with the rear surface of the bottom fixing block. The central fixing block includes a lower fixing structure connected to the bottom fixing block for supporting the second detection component, an upper fixing structure provided on the upper surface side of the lower fixing structure for supporting the second detection component, and a device On the other side of the upper surface of the lower fixing structure, the first joint is slidingly fitted with the top fixing block. The bottom of the top fixing block is provided with a second engaging portion slidingly fitted with the first engaging portion. The first joint portion includes a plate-shaped member. The second joint portion includes a vertical portion extending downward from the left and right edges of the lower surface of the bottom fixing block, a horizontal portion extending horizontally inward from the end of the vertical portion, and a horizontal portion bent upward from the end of the horizontal portion. The vertical portion, the bending portion and the lower surface of the bottom fixing block form a sliding groove that is matched with the edge of the plate-shaped member. The lower surface of the bottom fixing block is formed with at least one protrusion that abuts against the upper surface of the plate-shaped member. The fixing member is provided with a plurality of probe passing holes, and the first outer sleeve or the second outer sleeve is accommodated in the probe passing holes. The top fixing block is provided with a handle.

The fixing part used to support the detection part in the patch cord device for electric energy meter detection of the present invention includes a bottom fixing block used to support the first detection part, a middle fixing block and a top fixing block used to support the second detection part , Compatible with more types of electric energy meters, increasing versatility.
