In addition, there is sufficient surface contact with the pressing surface and the locking piece, and there is no difference in level between the conductors.Therefore, the electrical connection is stable and disconnection of the wires can be prevented.

〔Example〕

An embodiment of the present invention will be described based on FIGS. 1 to 6. That is, this insulated trolley wire connection device has a conductor joint 1 and a pressure spring means 2.

The conductor joint 1 is a rod-shaped body having a U-shaped cross section, and has a pair of locking pieces 5.6 that protrude inward from the opening edge. The locking piece 5.6 is not parallel to the bottom piece 7, as shown in FIG. 4, but is inclined away from the bottom piece 7.

The pressure spring means 2 is disposed on the inner surface of the bottom piece 7 of the conductor joint 1 to raise a pressing surface 8 facing the inside of the locking pieces 5 and 6, and also to push the pressing surface 8 against the locking pieces 5 and 6. It develops a spring 9 that urges inward. The spring 9 in the embodiment is the fifth

A presser plate 10 is disposed on the front side of this leaf spring, and the front surface of the presser plate 0 serves as a pressing surface 8. and the center part 9a of the spring 9
is brought into contact with the bottom piece 7, and both ends are brought out from both ends of the conductor joint 10, and the pressing surface 8 of the holding plate IO is brought into elastic contact with the inside of the locking pieces 5 and 6 by the spring force of the spring 9. Further, both ends 13 of the presser plate 1o are connected to the insulating trolley #i13. It is curved toward the spring 9 side so that the conductors II and +2 of No. 4 can be easily inserted.

A pair of insulated trolley wires 3.4 are connected to both ends 1 of the conductor joint l.

While pressing the pressing surface 8 against the spring 9 of the conductor 11.1
2, while engaging the grooves I6 with the edges of the locking pieces 5, 6 of the conductor joint l.

In this case, even if the conductor 11.12 has a bend as shown in FIG. 14, the groove 16 is deformed in the direction of bending or elongation when pushed along the edge of the locking piece 5.6. Since it is straightened, the bend will disappear. As a result, conductor 1
