3 binding posts 2 are provided with installation notch between the adjacent terminal 2 in same wiring group, and the depth of the installation notch is 2mm,
It is mounted therein with label 3, and installation notch are rectangular configuration, the label 3 includes board body 31 and is arranged in 31 both sides of board body
Support leg 33, the board body 31 match with installation notch, are rectangular configuration, the length of the support leg 33 and installation notch
Depth is identical, and support leg 33 is structure as a whole with board body 31, and the slot bottom of the installation notch is provided with threaded hole, the board body 31
The position of upper corresponding threaded hole is provided with through-hole 32, and bolt is tightened in after passing through the through-hole 32 on board body 31 in threaded hole, the board
The upper surface of body 31 is flushed with the upper surface of terminal plate 1.
A kind of above-mentioned current transformer is fixed on installation notch by opening up installation notch on terminal plate 1, and by label 3
Interior, connection is reliable, stablizes, and the upper surface of label 3 is flushed with the upper surface of terminal plate 1, does not affect wiring, in addition, logical
Reasonable layout binding post 2 is crossed, effectively improves security performance, it is simple in structure, be easily achieved.
Above example is to elaborate the basic principle and characteristic of the utility model, and the utility model is not by above-mentioned implementation
Example limitation, on the premise of not departing from the spirit and scope of the utility model, the utility model also has various changes, these
Changes and modifications are both fallen in claimed the scope of the utility model.The utility model requires protection scope is by appended right
Claim defines.
