Embodiment 1

[0028] Referring to Figures 1-2, this embodiment includes a fixed piece 1 fixed to the busbar and a finger 2 arranged on one side of the fixed piece. A fixing hole 3 is arranged on the top, and the fork 2 is in the shape of a long strip, and a fixing hole 4 is arranged at the end. In this embodiment, the fixing hole 3 on the fixing piece 1 is arranged in the middle of the fixing piece 1 , and the fingers 2 are respectively arranged on both sides of the fixing hole 3 .

Embodiment 2

[0030] 3-4, the basic structure of this embodiment is the same as that of Embodiment 1, the difference is that an upward protrusion 5 is provided in the middle of the fixed piece 1, and a fixing hole 3 is provided on the protrusion 5, and the fingers 2 are respectively arranged on the protrusions. On both sides of the raised 5, the height of the protrusion 5 is the same as that of the fork 2.

Embodiment 3

[0032] Referring to FIG. 5 , the basic structure of this embodiment is the same as that of Embodiment 1, except that the fixing hole 3 on the fixing piece 1 is set at one end of the fixing piece 1 , and the fork 2 includes two groups, which are symmetrically arranged at the other end of the fixing piece 1 .

Abstract

The present invention provides an interdigital instrument terminal bus bar, which comprises a stator fixed with the bus bar, a strip finger fixed on one side of the stator and fixing holes on the stator. Wherein, fixing holes are arranged at one end of the finger. The finger is higher than a right angle of a corner while the stator is fixed. With a simple and rational structure, the present invention can not only effectively improve measuring precision of electric energy meters of different COS Phi but also eliminate impact amongst users of electric energy meters.

Description

(1) Technical field [0001] The invention relates to electric energy measurement and verification technology, in particular to an electric energy meter terminal. (2) Background technology [0002] At present, almost all terminal combinations used in energy meter products, including terminals, busbars and shunts, adopt a rectangular ring structure. When the COSΦ of the single energy meter with the combination structure of the rectangular ring terminal is different, the accuracy varies greatly. The multi-user electric energy meter with the combination structure of the rectangular ring terminal will also be affected by the household. Therefore, the structure of the meter terminal has a great influence on the accuracy of the electric energy metering device and the calibration device, and there is no meter terminal structure on the market that can overcome the defects of the rectangular ring structure. (3) Contents of the invention [0003] The purpose of the present invention...
