Description

[Detailed description of the invention] This invention relates to a terminal device that tightens and connects electric wires by tightening screws, and is equipped with a spring presser foot to improve the tightening force of the electric wires and prevent the screws from loosening. The purpose is to

The present invention will be explained below with reference to the drawings showing one embodiment of the present invention. Reference numeral 1 denotes a terminal fitting, which is composed of an upper plate 2 and a lower plate 3 corresponding to the upper plate 2Vc.

Incidentally, the upper and lower plates 2 and 3 are connected by a side plate 4.

Reference numeral 5 denotes a tightening screw screwed into the upper plate 2, 6 an insertion opening for the electric wire T provided in the side plate 4, and 7 an insulating material stand to which the upper plate 2 is fixed.

3 is a horizontal U-shaped presser foot made of conductive spring material, and upper and lower pieces 9 are biased in a direction in which their tips approach each other
10, and its tips 9a and 10b face toward the wire insertion port 6, and the lower plate 3 of the terminal fitting 1 is interposed between the upper and lower pieces 9 and 10.

The upper piece 9 is coupled to the lower end 5a of the screw 5 while allowing the screw 5 to rotate, and moves up and down as the screw 5 moves forward and backward.

As described above, the present invention comprises a horizontal U-shaped presser foot 8 consisting of upper and lower pieces 9° and 10, each of which is biased by a spring force in a direction in which the ends of the presser foot 8 approach each other using conductive spring material. Upper and lower pieces 9,
Place the upper and lower pieces 9, 1 with the tips of 10 facing the wire insertion port 6.
The lower plate 3 of the terminal fitting 1 is interposed between the upper piece 9 of the presser foot 8 and the lower plate 3 of the terminal fitting 1, and the upper piece 9 is rotatably connected to the lower end 5a of the tightening screw 5. Since the electric wire T inserted between the
It moves up and down with the rotation of the wire T to hold down the wire T, and the spring force of the spring material improves the tightening force of the wire and also prevents the screw 5 from loosening.

Further, since the screw 5 and the presser foot 8 are connected, the presser foot 8 will not shift or come off when the electric wire is inserted, and the screw 5 can be prevented from falling off during transportation.
